How the Colorado Itemization Requirement Works

Colorado’s security deposit rules live in the Colorado Revised Statutes at C.R.S. § 38-12-101 through § 38-12-104. At the center of those rules sits a single document requirement: whenever a landlord keeps any portion of a deposit, the landlord must deliver to the tenant a written statement that lists the exact reasons for the retention. That statement is the itemization. It is not a courtesy summary and it is not optional; it is the specific paperwork the statute conditions the entire right to withhold upon. An itemization is the accounting schedule — the deposit held on one side, each lawful charge broken out on the other, and the balance that results. If you also need the cover page that transmits the schedule to the tenant, pair this worksheet with our Colorado security deposit return letter, which carries the same math into a mailable format.

The reason the itemization matters so much is structural. The deposit is the tenant’s money that the landlord merely holds, so the burden sits entirely on the landlord to justify keeping any part of it. A precise, itemized schedule is how a landlord carries that burden. A vague note that says cleaning and repairs, four hundred dollars does not carry it; a schedule that names oven and range cleaning at ninety dollars, carpet stain repair in the second bedroom at one hundred sixty dollars, and unpaid final-month utilities at one hundred fifty dollars does. The specificity is what turns a contested deduction into a documented one. Colorado’s broader framework is covered in our Colorado security deposit laws guide, which sets the itemization inside the full statute.

The One-Month Delivery Deadline (C.R.S. § 38-12-103(1))

Under subsection (1), a landlord must return the full deposit — or the balance after lawful deductions, together with the written itemization — within one month after the lease terminates or after the tenant surrenders and the landlord accepts the premises, whichever happens last. A written lease may extend that window, but never beyond sixty days. If the lease is silent, the one-month deadline governs by default, and a landlord cannot assume the longer period without lease language to support it. The itemization and the refund travel together: delivering the money without the statement, or the statement without the money, does not satisfy the subsection.

The clock starts at surrender of possession, not at the lease’s calendar end date and not when the last repair invoice arrives. In practice the deadline often lands before every final invoice is in hand. The correct response is to build the itemization with good-faith estimates and deliver on time, because the 2026 amendments expressly treat estimates as acceptable supporting documentation. Waiting for a final number and blowing the deadline is the worst possible trade. If the tenancy is ending early, our guide on how to terminate a lease early explains how surrender fixes the date the itemization clock runs from.

What the 2026 Amendments Changed (HB25-1249)

House Bill 25-1249 took effect on January 1, 2026 and tightened the statute in ways that change how an itemization must be built. The delivery deadline itself did not move, but what a landlord may list, and what a landlord must be able to produce, changed substantially. Every line on the schedule below should be read against the amended law.

• No wear-and-tear or preexisting lines. A landlord may not itemize a deduction for normal wear and tear or for damage or a defective condition that existed before the tenancy began.
• Only reasonable, documented amounts. Withholding is limited to reasonable sums for unpaid rent, unpaid utilities, other lawful charges named in the lease, and necessary repairs for damage exceeding normal wear that did not preexist the tenancy.
• Documentation on demand. If the tenant asks, the landlord must provide all supporting documentation in their possession — photographs, inspection forms or reports, receipts, invoices, or estimates — within fourteen days of the request.
• Carpet and paint limits. A landlord generally cannot itemize a full carpet replacement or full repaint where only part is damaged, and carpet that was not replaced with new carpet within the prior ten years cannot be deemed substantially and irreparably damaged.
• A 125 percent red line. An amount retained is presumed to unreasonably exceed the actual damages if it reaches one hundred twenty-five percent or more of the documented actual damages.

Anatomy of a Compliant Itemization Statement

A defensible itemization is built from a fixed set of elements. Missing any one of them is the most common way an otherwise fair deduction package fails when a tenant challenges it. Treat the schedule the generator produces as a checklist as much as a calculator.

Parties and property identification

Name every tenant on the lease, the landlord or property manager, the rental address, and the tenant’s forwarding address. The forwarding address is where the itemization and any refund must go; collecting it in writing at move-out removes a frequent excuse for late or misdirected delivery.

The deposit held, stated exactly

State the security deposit and any refundable pet deposit precisely. If a last-month rent credit was collected as prepaid rent rather than as a deposit, keep it out of the deposit total so the accounting reflects only deposit money. The generator on this page subtracts a last-month credit for you so the net figure is clean.

Each deduction as its own line

List every charge separately with a specific description, a category, and an amount. Bundling several repairs into one lump sum invites a challenge because the tenant cannot test any single figure against a receipt. One line, one charge, one number, one piece of proof is the standard to aim for.

The arithmetic, shown

Total the deductions, subtract them from the net deposit, and state the resulting refund — or, where the charges exceed the deposit, the balance the tenant still owes. Showing the math is not decoration; it is how the tenant, and later a judge, confirms that the numbers add up.

Forfeiture: A Late Itemization Costs Everything (Subsection (2))

Subsection (2) is blunt: the failure of a landlord to provide the written statement within the required time works a forfeiture of all rights to withhold any portion of the security deposit. There is no partial credit and no good-faith exception for a late statement. A landlord genuinely owed a legitimate amount for unpaid rent, but who delivers the itemization one day late, loses the right to keep even that legitimate amount and must return the entire deposit.

This is why the deadline dominates every other consideration on the schedule. A flawlessly itemized statement delivered late is worth nothing under subsection (2); a plainly documented statement delivered on time protects the entire deduction package. Treat the calendar, not the paperwork polish, as your first priority, and use certified mail so you can prove the delivery date. When a repair invoice is still pending, itemize the estimate and deliver on time rather than holding the statement for a final number.

Treble Damages, Attorney Fees, and the 7-Day Notice (Subsection (3))

Subsection (3) supplies the financial teeth behind the itemization requirement. A landlord who willfully retains a deposit in violation of the statute is liable for treble — three times — the amount wrongfully withheld, together with reasonable attorney fees and court costs. The trebling applies to the wrongfully withheld portion, so a single over-aggressive line can multiply into a much larger judgment once fees are layered on. A deposit of two thousand dollars withheld in bad faith can become a six-thousand-dollar exposure before the tenant’s legal fees are even counted.

The statute builds in one procedural step that favors landlords: before filing suit, the tenant must give the landlord at least seven days written notice of the intention to file legal proceedings. That seven-day window is a genuine chance to cure — a landlord who receives such a notice and promptly returns the disputed amount can often avoid the treble exposure entirely. Landlords who want the wider liability picture should review our landlord retaliation guide, since deposit disputes and retaliation claims frequently travel together.

Lawful Deduction Categories vs. Normal Wear and Tear

The line between a lawful itemized charge and non-deductible wear is where most disputes are won or lost. Colorado treats normal wear and tear as deterioration that occurs, based on the intended use of the unit, without negligence, carelessness, accident, or abuse by the tenant, the tenant’s household, or their guests. Everyday aging of a unit is the landlord’s cost of doing business and cannot appear on the itemization; damage from misuse can.

Generally Deductible (documented, exceeds wear)

• Unpaid rent owed through the end of the tenancy.
• Unpaid utilities the tenant was responsible for under the lease.
• Repair of holes, breaks, burns, or stains that exceed normal wear and did not preexist the tenancy.
• Cleaning needed only where the unit is left excessively dirty beyond ordinary use.
• Other lawful charges expressly listed in the lease, such as an agreed key-replacement fee.

Never Deductible (normal wear and tear)

• Minor scuffs, nail holes, and faded paint from ordinary occupancy.
• Carpet worn in high-traffic paths from everyday walking, or carpet older than ten years.
• Minor scratches on floors and worn spots on countertops.
• Any condition that already existed when the tenant moved in.

Common Mistakes on Colorado Itemizations

Most deposit judgments trace back to a small number of avoidable itemization errors. Reviewing them before you finalize the schedule is the cheapest insurance available.

• Lumping charges together. A single line reading repairs and cleaning defeats the whole point of an itemization; break every charge out.
• Counting from the wrong date. Starting the clock at the lease end date instead of the surrender date can silently blow the one-month deadline.
• Assuming the sixty-day window. The longer period applies only if the lease actually says so in writing.
• Itemizing wear and tear. A line for faded paint or path-worn carpet is exactly the deduction the 2026 amendments prohibit.
• Padding above documented cost. Any line at or above one hundred twenty-five percent of the real, provable cost is presumptively unreasonable.
• Keeping no proof. Without photos, invoices, or estimates, a line cannot survive a tenant’s fourteen-day demand or a courtroom.

Best Practices for a Defensible Itemization

1. Document move-in condition with a dated move-in inspection and photographs so preexisting conditions are provable and never itemized.
2. Collect the tenant’s forwarding address in writing at move-out.
3. Conduct a move-out walk-through; either party may request an inspection under the 2026 law.
4. Photograph any damage before you repair it, and keep every receipt, invoice, and estimate keyed to its line.
5. Complete this schedule, let the form total the deductions, and double-check the resulting balance.
6. Deliver the itemization and any refund by certified mail with return receipt before the deadline.
7. Keep a full copy of the signed itemization and its documentation package for your records.

Building the Documentation Package Behind Each Line

An itemization is only as strong as the evidence stacked behind it. Because the 2026 amendments let a tenant demand every supporting document within fourteen days, the practical rule is to assemble the package as you build the schedule, not after a demand arrives. For each line, keep the item that proves it: a paid invoice for completed repair work, a written third-party estimate for work not yet done, dated before-and-after photographs, and the relevant page of the move-in and move-out inspection records. Label each piece with the line it supports so that producing the package is a matter of copying a folder rather than reconstructing a case.

The discipline pays off twice. First, a tenant who receives a clean itemization backed by matching proof rarely files, because the deduction is visibly defensible. Second, if the matter does reach small claims court, the burden is on the landlord to prove each deduction, and a pre-assembled package is exactly that proof. Our rental property inspection guide walks through the photo and checklist habits that make this package come together almost automatically at move-out.

The Move-Out Walk-Through Inspection

The 2026 amendments formalized a walk-through inspection right that experienced landlords already used as best practice, and it feeds directly into a clean itemization. Upon a request by either the landlord or the tenant, and where reasonable and practicable, the parties may conduct a joint inspection of the unit to identify any damage that exceeds normal wear and tear. The inspection can be in person or, where the parties agree, virtual. The value of this step is not the ceremony but the record: a shared, contemporaneous account of the unit’s condition removes most of the ambiguity that later fuels a deposit fight.

For the itemization specifically, the walk-through is an early test of every line you plan to enter. If the tenant sees the same gouged door or stained carpet you intend to charge for, that line becomes far harder to dispute later. Conversely, if a condition you assumed was tenant damage turns out to be a preexisting defect on your own move-in paperwork, you learn that before you enter an unlawful line that could trigger forfeiture of the whole schedule. A tenant who declines the offered inspection cannot later claim surprise at a well-documented deduction.

The 125 Percent Presumption in Practice

One of the sharpest tools the 2026 law hands tenants is a presumption aimed straight at inflated line items. If the amount a landlord retains on any basis reaches one hundred twenty-five percent or more of the documented actual damages, the retention is presumed to unreasonably exceed those damages. In plain terms, padding a line beyond the real, provable cost is now presumptively unreasonable, and unreasonable retention is exactly the conduct that leads to treble-damage exposure. The presumption shifts the practical burden onto a landlord who has stretched a number.

The lesson for the itemization is discipline on every line. Each entry should map to a receipt, an invoice, or a good-faith written estimate, and the amount should sit at or near the documented cost rather than a comfortable margin above it. If a repair genuinely costs two hundred dollars, itemize two hundred dollars and attach the proof, not two hundred sixty. Resist the temptation to round up, to bundle vague charges, or to add a cushion for inconvenience. The generator keeps your arithmetic honest by summing only the amounts you enter, but the reasonableness of each amount is a judgment you must make against real documentation.

When Deductions Exceed the Deposit

Sometimes the lawful charges genuinely exceed the deposit held — months of unpaid rent plus real damage can easily outrun a one-month deposit. The itemization does not stop being required in that situation; it becomes even more important. Deliver the full itemized schedule on time, show every line, and state the balance the tenant still owes after the deposit is fully applied. The deadline and forfeiture rules still bite: a landlord who is owed money but never delivers the statement can still forfeit the right to apply the deposit at all, converting a partial loss into a total one.

Once the deposit is exhausted and a balance remains, that balance is an ordinary debt the landlord may pursue separately, typically in small claims court, subject to the same documentation burden. The generator flags this case for you: when deductions exceed the net deposit, the summary switches from a refund figure to a balance-owed figure and the PDF states the amount the tenant still owes. Keep the itemization and its proof package intact, because the same evidence that justified withholding the deposit is what supports a claim for the remainder.

A Worked Example: Reading the Schedule End to End

Walking one deposit through the schedule makes the mechanics concrete. Suppose a landlord held a security deposit of one thousand five hundred dollars and a refundable pet deposit of three hundred dollars, and that no last-month rent credit was collected as a deposit. The net deposit to account for is one thousand eight hundred dollars — that figure, not the security deposit alone, is what the itemization must reconcile. Everything else on the schedule works down from there.

Now suppose three lawful lines. The tenant left owing four hundred fifty dollars in final-month rent, which is entered as an unpaid-rent line at four hundred fifty dollars and backed by the ledger. A cracked interior door from a slammed handle, exceeding normal wear, costs one hundred eighty dollars to replace on a paid invoice, entered as a damage-beyond-wear line. And the oven and range required professional cleaning beyond ordinary move-out condition at ninety dollars, entered as an excessive-cleaning line with the cleaner’s receipt. The three lines total seven hundred twenty dollars. Subtract that from the net deposit of one thousand eight hundred dollars and the refund due to the tenant is one thousand eighty dollars. The generator produces exactly that number, and the PDF states it as the refund due.

Change one fact and the schedule flips. If instead the tenant left owing two thousand one hundred dollars in unpaid rent, that single line already exceeds the one thousand eight hundred dollar net deposit. The schedule now shows total deductions of two thousand one hundred dollars against a net deposit of one thousand eight hundred dollars, so no refund is due and a balance of three hundred dollars remains owed by the tenant. The summary switches its label to balance owed and the PDF states three hundred dollars as the amount the tenant still owes. The itemization is still required and still must go out on time; the landlord simply pursues the three hundred dollar remainder as an ordinary debt, backed by the same rent ledger that supported the line.

Deposit Caps and Pet Deposits Colorado Landlords Should Know

The itemization only ever accounts for money the landlord was entitled to hold in the first place, so the front-end deposit rules matter to the accounting. Colorado law limits a residential security deposit to no more than the equivalent of two months rent. A refundable pet deposit is capped separately and may not exceed three hundred dollars, and any pet-related rent surcharge is likewise constrained. Because these caps changed with recent legislation, confirm the current figure for your situation before relying on a specific number; the safe practice is to never collect more than the current statutory maximum, since an overcollected deposit invites its own claim independent of the itemization.

The practical link to the itemization is that a refundable pet deposit is deposit money and belongs on the schedule, while a non-refundable fee, where permitted, is not deposit money and does not. Keep the categories separate at collection so the accounting at move-out is clean. If you collected a distinct pet deposit, enter it in the pet-deposit field so the net deposit the schedule reconciles is complete; a pet deposit quietly left off the accounting is a common way landlords underreport what they were holding, which surfaces badly if the tenant produces the original lease showing the larger sum.

Multiple Tenants and Apportioning One Deposit

When several tenants share a lease, they typically share a single deposit, and the itemization accounts for that one deposit rather than splitting it by person. The statement is delivered to the tenants jointly at the forwarding address they provide, and any refund is likewise one figure. Landlords sometimes feel pressure to divide a refund among departing roommates, but the deposit is a single obligation under the lease; unless the lease or a written agreement among the tenants directs otherwise, the cleanest course is to return the single balance to the tenants together and let them settle any internal division among themselves.

Where roommates leave at different times, the deposit obligation does not reset with each departure; it runs from the end of the tenancy as a whole. A landlord who returns a portion to an early-leaving roommate and then faces damage caused later can find the accounting muddled and the deadline mismeasured. The disciplined approach is to hold the full deposit until the tenancy actually ends, then build one itemization against the surrender date. If your leases frequently involve roommates, our landlord move-out checklist helps standardize the surrender documentation that fixes the itemization clock for the group.

Certified Mail and the Evidence of On-Time Delivery

Because subsection (2) forfeits the entire right to withhold when the statement is late, proving the delivery date is nearly as important as the contents of the itemization. Colorado does not mandate certified mail, but certified mail with return receipt is the simplest way to fix the date in evidence. Mail the itemization and any refund to the tenant’s written forwarding address, keep the certified receipt and the tracking record, and photograph the sealed envelope with its postmark. If you deliver by hand or by a method the lease authorizes, document the date and manner the same way. The goal is that, months later, you can show a neutral record of when the statement went out.

Timing discipline also means working backward from the deadline rather than forward from the repairs. Calendar the surrender date, count the one-month window (or the sixty-day window only if the lease actually grants it), and set an internal target several days early to allow for mail transit and a returned envelope. A statement that arrives on day thirty-one is late even if it was mailed on day twenty-nine, so build in margin. If a repair invoice will not arrive in time, itemize the good-faith estimate and deliver on schedule; a later corrected figure is a manageable problem, while a missed deadline is a total forfeiture.

Interest, Transfers, and Returned Refunds

Colorado’s statewide statute does not impose a general interest requirement on residential security deposits, though a landlord should always check for any local ordinance in the specific municipality, since a handful of jurisdictions add their own rules on top of state law. The deposit is the tenant’s money held for the performance of the lease, and the cleanest practice is to keep it segregated and untouched until the itemization is complete. When ownership of the property changes hands, the deposit obligation moves with it under a sixty-day transfer window, so a departing owner cannot strand the sitting tenants and an incoming owner inherits the accounting duty. If a refund check is later returned undelivered or uncashed, the landlord is expected to hold the funds rather than treat them as forfeited and to disburse them promptly on the tenant’s later request. A returned refund does not end the obligation the itemization created.

Why the Category on Each Line Matters

The schedule asks for a category on every line — unpaid rent, unpaid utilities, damage beyond wear, excessive cleaning, or another lawful lease charge — because the category is what ties each entry to the specific statutory basis that permits it. Colorado does not allow a landlord to withhold for any reason that feels fair; it allows withholding only for a defined set of lawful bases, and naming the category forces each line to declare which one it rests on. A charge that cannot be honestly assigned to a lawful category usually should not be on the itemization at all, which makes the dropdown a quiet compliance check as much as a formatting choice.

Categorizing also makes the statement easier for a tenant, and later a court, to read and accept. An unpaid-rent line points to the lease ledger; an unpaid-utilities line points to the lease clause assigning that utility to the tenant and the final bill; a damage-beyond-wear line points to the before-and-after photographs and the repair invoice; an excessive-cleaning line points to the move-out photographs and the cleaner’s receipt. When the category and its natural proof line up on every entry, the itemization reads as a coherent, documented accounting rather than a list of assertions. That coherence is what turns a schedule into an exhibit that resolves a dispute instead of starting one.

When the Tenant Leaves No Forwarding Address

A tenant who moves out without giving a forwarding address does not excuse the landlord from the itemization requirement, and it does not pause the deadline. The obligation to prepare the written statement and account for the deposit runs from surrender regardless of whether the tenant has provided an address, so the safe practice is to build the itemization on time and send it to the last known address the landlord has — typically the rental unit itself or any address on file from the application or lease. Sending it, and keeping proof that you sent it, preserves the record that you met the deadline even if the mail is later returned undelivered.

If the statement and refund come back because the tenant cannot be located, hold the funds rather than treating them as forfeited to the landlord, and keep the returned envelope unopened as evidence of the delivery attempt. The tenant’s money remains the tenant’s money; when the tenant later surfaces with a valid address, disburse promptly. Documenting the attempt matters because a tenant who reappears and claims the itemization was never delivered is met with a certified-mail receipt and a returned envelope showing a good-faith, on-time effort. The lesson is that an uncooperative or vanished tenant increases, rather than decreases, the value of meticulous delivery records.

Itemization vs. Return Letter: Two Documents, One Accounting

Landlords sometimes ask whether the itemization and the cover letter are the same thing. They are related but distinct. The itemization is the accounting schedule: the deposit held, each lawful line, the totals, and the resulting balance — the written statement of exact reasons the statute requires. The cover letter is the transmittal that wraps around it, addressed to the tenant, explaining what is enclosed and directing the refund to the forwarding address. A landlord can satisfy the statute with the itemization alone, since the statement of reasons is what subsection (1) demands, but pairing the schedule with a short cover letter is cleaner practice and reads better if a dispute arises.

The two documents share one set of numbers, which is why building the itemization first keeps everything consistent. Generate the itemization here, confirm the arithmetic, then carry the identical figures into the Colorado security deposit return letter so the cover page and the schedule never disagree. A mismatch between a letter that promises one refund and a schedule that computes another is exactly the kind of inconsistency a tenant will seize on, so let the itemization be the single source of truth and the letter simply transmit it.

If the Tenant Disputes: The Seven-Day Notice and Small Claims

Most itemization disputes that reach a courtroom land in small claims court, where the process is designed to be navigable without a lawyer. Before a tenant can pursue treble damages, subsection (3) requires them to serve the landlord with at least seven days written notice of an intent to file legal proceedings. That notice is not a formality to be ignored; it is the landlord’s last clear chance to return a wrongly withheld amount and cap the exposure before trebling and fees attach. A landlord who receives such a notice, reviews the challenged lines honestly, and refunds any that cannot be documented often ends the matter for a fraction of the potential judgment.

When a case does proceed, the burden is on the landlord to prove that each deduction was lawful, which is precisely why the itemization and its evidence package decide the outcome. A landlord who can lay down an on-time, line-by-line statement matched to receipts, invoices, estimates, and dated photographs almost never loses, because every number is testable. A landlord who offers a lump sum and a verbal explanation almost always struggles, because there is nothing for the court to verify. The itemization is not paperwork for its own sake; it is the exhibit list for a case you hope never to try. Understanding the wider set of obligations, including the Colorado habitability rules that can surface as tenant counterclaims, keeps you from walking into a dispute you did not anticipate.

It also helps to understand what willful means in this context. The trebling in subsection (3) attaches to willful retention, not to an honest arithmetic slip or a good-faith line later found unpersuasive. A landlord who itemizes carefully, documents each line, and delivers on time demonstrates good faith even where a court ultimately disallows a particular charge. The danger zone is the deduction taken with no documentation, the number padded well past its provable cost, or the statement delivered late — each of which a court can read as the kind of conduct the treble remedy exists to deter. Care in building the itemization is, in a real sense, the landlord’s insurance against the willfulness finding.

The Move-In Baseline That Protects Every Line

Every lawful line on a move-out itemization is really a comparison: the unit’s condition at surrender measured against its condition when the tenant took possession. That comparison only works if the move-in condition was documented, which is why the strongest itemizations are built long before move-out. A dated, photographed move-in inspection, ideally signed by the tenant, establishes the baseline that separates tenant-caused damage from a preexisting defect the 2026 amendments forbid you from charging. Without that baseline, a tenant can plausibly claim that the gouge, the stain, or the broken fixture was there all along, and the landlord has no record to rebut it.

Treat the move-in record as the first half of the itemization even though it is created at the start of the tenancy. Photograph each room, note existing wear on a checklist, and have the tenant acknowledge the condition in writing. At move-out, the same rooms are photographed again, and the difference between the two sets of images is the evidentiary heart of each damage line. Our guide to the move-in inspection lays out a repeatable process, and pairing it with the move-out walk-through gives you a clean before-and-after for every charge you enter. A landlord who does this consistently rarely faces a serious itemization challenge, because each disputed line answers itself in the photographs.

Frequently Asked Questions: Colorado Itemization FAQ

What exactly is the itemization statement?

It is the written statement of exact reasons for retention that C.R.S. § 38-12-103(1) requires whenever any part of the deposit is withheld — the line-by-line accounting schedule, distinct from the cover letter that transmits it.

How long do I have to deliver it?

One month after the lease terminates or the tenant surrenders the premises, whichever is last, unless the written lease specifies a longer period up to sixty days (C.R.S. § 38-12-103(1)).

What if the itemization is one day late?

Under subsection (2), a late statement forfeits all right to withhold, so you must return the entire deposit even if some lines were legitimate.

How bad are the penalties?

Willful over-withholding exposes you to treble damages plus reasonable attorney fees and court costs under subsection (3).

Can I itemize repainting or new carpet?

Only where the damage is substantial and exceeds normal wear; you generally cannot charge a full replacement for partial damage, and carpet older than ten years carries a specific restriction under the 2026 amendments.

What documentation must back each line?

Photographs, inspection forms or reports, receipts, invoices, or estimates — and you must provide them within fourteen days if the tenant asks.

What if my deductions are larger than the deposit?

Still deliver the full itemization on time, apply the deposit to the balance, and pursue any remaining amount separately; the form shows the balance owed for you.
