Hawaii Rent Increase Laws: The Landlord and Tenant Guide
No Statewide Cap · 45-Day Written Notice · No Mid-Term Increase · Termination Rules · Retaliation and Fair-Housing Limits
Hawaii is a free-market rent state: there is no statewide cap on how much a landlord may raise the rent, and no county has adopted rent control. But “no cap” does not mean “no rules.” The Hawaii Residential Landlord-Tenant Code, Hawaii Revised Statutes chapter 521, controls how and when a raise is delivered — most importantly a 45-day written-notice requirement on a month-to-month tenancy under Hawaii Revised Statutes section 521-21. On top of that sit a no-mid-term-increase rule, anti-retaliation protection under section 521-74, source-of-income and fair-housing limits, and the possibility of an emergency rent freeze. Get the amount right but the notice or the timing wrong, and the increase does not take effect. This guide walks the whole framework end to end, in plain English, with every rule tied to a concrete action.
The stakes are practical. Because Hawaii sets no dollar limit, the fight is almost never about how much — it is about whether the raise was delivered lawfully. An increase served with too few days, imposed in the middle of a fixed lease, or timed right after a tenant complaint is defective, and a tenant can keep paying the old rent or use the defect against a later eviction. And because rent-control bills are proposed in the Legislature from time to time and emergency proclamations can freeze rents in a disaster area, treat every rule here as a starting point and verify the current law for the property’s island and county before you serve anything.
Below, a detailed overview video summarizes the Hawaii framework; the sections that follow break down each piece — why there is no cap, the 45 and 15-day notice rules, when you may raise rent at all, the termination-notice tie-in, retaliation, fair housing and source of income, emergency freezes, and a step-by-step landlord playbook — plus a Hawaii-specific FAQ.

No Statewide Cap: What Hawaii Does and Does Not Limit
The first thing to understand about Hawaii rent-increase law is what is not there. Hawaii has no statewide rent cap and no rent control. The Residential Landlord-Tenant Code does not set a maximum percentage or dollar amount, and no formula ties an allowable increase to inflation the way some mainland states do. For most rentals, a landlord may set a lawful increase at whatever the market will bear — the legal questions are about the notice, the timing, and the reason, not the size.
Why There Is No Cap, and Where a Cap Could Come From
Hawaii’s Legislature has considered rent-control and rent-stabilization bills in various sessions, but none has become law, so the free-market default stands. Two narrow paths could still produce a limit. First, a county could adopt a local rent-control or rent-stabilization ordinance under its own powers; Hawaii Revised Statutes section 666-20 is a savings clause that preserves such an emergency ordinance from being overridden by the landlord-tenant code rather than an affirmative grant of that power, and the enabling statutes it originally referenced have been repealed. As of 2026, no Hawaii county — Honolulu, Hawaii, Maui, or Kauai — has enacted one, but that could change. Second, during a declared state of emergency the Governor or a mayor may restrict price increases, including rent, under the state’s emergency-management law. Because both paths can shift with an election cycle or a disaster, confirm the current status for the specific island before relying on the no-cap rule.
“No cap” is not “no limit”
It is easy to read “Hawaii has no rent control” as “a landlord can do anything.” That is wrong. The absence of a cap answers only the how much question. The how and why questions — proper written notice, no mid-term increase without lease authority, no retaliation, no discrimination, no violation of an emergency freeze — are fully regulated. A raise that flunks any of those is unlawful no matter how modest the dollar figure.
Watch for pending legislation and county action
Rent-stabilization proposals surface in the Hawaii Legislature from session to session, and a bill that passes could impose an annual cap or a first-year freeze on new tenancies. Similarly, a county could adopt its own rent-control ordinance. Do not assume last year’s free-market answer still holds; check for a newly enacted state law or county ordinance before you set a number.
Takeaway
Hawaii has no statewide rent cap and no rent control, so the amount of an increase is generally unrestricted. The real compliance work is in the notice, the timing, and the reason — and a county rent-control ordinance or an emergency proclamation could add a limit, so verify current law first.
Notice: The 45-Day Rule and How to Serve It
The single most important rule in Hawaii rent-increase law is the notice period. Even an increase the tenant would happily pay fails if it is delivered with the wrong notice. Hawaii Revised Statutes section 521-21 sets the written-notice period, and it turns on the length of the rental period.
| Type of tenancy | Minimum written notice before the increase | Statute |
|---|---|---|
| Month-to-month | At least 45 consecutive days before the effective date | Hawaii Revised Statutes section 521-21 |
| Less than month to month (for example, week-to-week) | At least 15 consecutive days before the effective date | Hawaii Revised Statutes section 521-21 |
| Fixed-term lease, during the term | No increase unless the lease expressly permits it | Hawaii Revised Statutes section 521-21 |
The statute is specific: for a month-to-month tenancy, the rent “shall not be increased by the landlord without written notice given forty-five consecutive days prior to the effective date of the increase.” The word consecutive means calendar days, weekends and holidays included, and the count runs to the effective date, so a raise meant to take effect on the first of a month must be delivered in writing at least 45 days earlier. For a tenancy shorter than a month, the same subsection cuts the period to 15 consecutive days.
What a Proper Notice Contains and How to Serve It
A defensible rent-increase notice is in writing and states, at minimum, the tenant’s name and the property address, the current rent, the new rent, and the effective date — with enough lead time to satisfy the 45-day (or 15-day) requirement counted from delivery. A verbal announcement, a text message, or an email the tenant never agreed to accept as a delivery method is not proper notice and does not start the clock. Serve it by a provable method — certified mail with return receipt, or personal delivery with a signed acknowledgment — and keep a copy of both the notice and the proof of delivery. If you serve by mail, build in extra transit days so the tenant still receives the full statutory period before the effective date.
Count the days from delivery, not from the date you wrote the notice
The 45 days run from when the tenant actually receives proper notice, not from the date typed at the top of the letter. If you mail the notice, the days the letter spends in transit do not count against the tenant. The safe practice is to serve well ahead of schedule and confirm the tenant has the full 45 consecutive days before the new rent begins. A notice that is a few days short simply does not raise the rent on the intended date.
A lease or a housing program can require longer
Section 521-21 sets a floor, not a ceiling. If a lease, a recorded regulatory agreement, or a subsidized-housing program requires a longer notice period than 45 days, the longer period controls. Federally subsidized and voucher-assisted tenancies frequently layer on extra notice and approval steps before a rent change takes effect, so a notice that satisfies the state minimum can still fall short of a program rule.
Takeaway
Give at least 45 consecutive days written notice on a month-to-month tenancy, or 15 days for a shorter period, under Hawaii Revised Statutes section 521-21. Put it in writing with the current rent, new rent, and effective date, serve it by a provable method, and count the full days from delivery.
When You Can Raise the Rent at All
The notice rule only matters once you actually have the right to raise the rent. That right depends on the tenancy.
During a Fixed-Term Lease: Generally Locked
While a fixed-term lease is running, the rent is set at the agreed amount for the whole term. Under Hawaii Revised Statutes section 521-21 the rent is payable as the parties agreed, and a landlord cannot raise it mid-term unless the lease itself contains an explicit clause that permits the change. Absent that clause, the tenant is entitled to the agreed rent through the end of the term, and a mid-term increase notice has no effect.
At Renewal or on a Month-to-Month Tenancy
The two ordinary windows to raise rent are when a fixed term ends and the parties negotiate a new term, and during a month-to-month tenancy, where a landlord may change the rent going forward by serving the required 45-day written notice. On a month-to-month, the increase takes effect only after the full 45 consecutive days run; the tenant can accept the new rent and stay, or serve a 28-day termination notice and move out. Because Hawaii sets no cap, the negotiation at renewal is where the market amount is really set — the statute governs the process, not the price.
A mid-term increase without authority is void
Trying to raise rent partway through a fixed-term lease with no lease clause does not simply fail quietly — the increase is unenforceable, and a tenant who keeps paying the original rent is in the right. Do not treat a tenant’s silence as agreement. Wait for the term to end, or move to a lawful month-to-month process with a proper 45-day notice, before adjusting the rent.
Takeaway
You may raise rent at renewal or on a month-to-month tenancy with the proper 45-day notice, but never mid-term on a fixed lease unless the lease expressly allows it. The tenancy type decides whether you even have the authority; the notice rule decides how.
The Termination-Notice Tie-In
Rent increases and tenancy terminations are linked, because a tenant who does not want to pay a raise has a way out. Hawaii Revised Statutes section 521-71 sets the notice periods for ending a month-to-month tenancy, and they mirror the rent-increase timeline.
| Who is ending the month-to-month tenancy | Minimum written notice |
|---|---|
| Tenant | At least 28 days before the intended termination date, with rent owed through the 28th day |
| Landlord | At least 45 days before the anticipated termination date |
The practical link is this: when a landlord serves a 45-day rent-increase notice, a tenant who rejects the new rent can serve a 28-day notice to terminate and be gone before the raise ever takes effect, paying the old rent through the move-out date. A landlord who instead wants to end the tenancy — rather than raise the rent — must give the tenant at least 45 days written notice. Understanding both notice tracks keeps a rent increase from turning into an accidental, defective termination.
Do not use a rent increase as a back-door eviction
A steep increase aimed at forcing a specific tenant out, rather than a genuine market adjustment, invites both a retaliation defense and, if a protected class or a housing voucher is involved, a fair-housing claim. If the real goal is to end the tenancy, use the 45-day landlord termination notice under section 521-71 and the proper eviction process, not an outsized rent hike. See our guide to Hawaii eviction notice laws and Hawaii lease termination laws for how those notices work.
Takeaway
Under Hawaii Revised Statutes section 521-71, a tenant ends a month-to-month tenancy with 28 days written notice and a landlord with 45 days. A tenant who rejects a raise can move out before it takes effect, so a rent increase should never be used as a substitute for a lawful termination.
Retaliation: A Raise Can Be Illegal Even Without a Cap
Hawaii’s strongest limit on rent increases is not a dollar figure — it is the ban on retaliation. Hawaii Revised Statutes section 521-74 makes it unlawful for a landlord to demand an increase in rent, recover possession, decrease services, or cause a tenant to quit involuntarily in retaliation for a tenant’s exercise of a protected right.
What Counts as Protected Tenant Activity
The statute protects a tenant who has, in good faith: complained to the landlord, the Department of Health, the building department, the Office of Consumer Protection, or another governmental agency about a condition that violates a health law or a provision of the Landlord-Tenant Code; had a government agency file a notice or complaint of such a violation; or requested repairs or the landlord’s compliance with the Code under Hawaii Revised Statutes sections 521-63 or 521-64. If a rent increase, a service cut, or an eviction move follows one of these acts, it can be challenged as retaliatory.
The presumption and the burden shift
When an increase or other adverse action lands shortly after protected activity, it is generally treated as presumptively retaliatory — courts commonly look at conduct within about a year of the tenant’s good-faith complaint — and the burden shifts to the landlord to show a legitimate, non-retaliatory business reason. The safest practice is to time increases to the ordinary schedule, such as a renewal or an annual anniversary, and to document the market and cost reasons behind the number. A tenant who is unlawfully dispossessed under section 521-74 may recover damages, the cost of suit, and reasonable attorney’s fees.
Timing is everything with retaliation
Because Hawaii has no rent cap, a landlord cannot defend a suspicious raise by pointing to a numeric limit — the only defense is a legitimate reason and clean timing. A raise issued a few weeks after a habitability complaint or a repair request is exactly the fact pattern section 521-74 targets. If a genuine market increase happens to fall near protected activity, document the business justification carefully before you serve it.
Takeaway
Under Hawaii Revised Statutes section 521-74, a rent increase is unlawful if it is retaliatory — issued after a good-faith repair request or code or health complaint. An increase soon after protected activity is presumptively retaliatory, shifting the burden to the landlord, who may owe damages and attorney’s fees. Time raises to the ordinary schedule and document the reason.
Fair Housing and Source of Income
A rent increase also cannot be used to discriminate, and Hawaii’s protections go beyond the federal baseline. An increase that clears the notice and retaliation rules is still unlawful if it targets a protected class or a lawful source of income.
Protected Classes Under Federal and Hawaii Law
The federal Fair Housing Act bars housing discrimination based on race, color, religion, national origin, sex, familial status, and disability. Hawaii’s own fair-housing law, Hawaii Revised Statutes chapter 515, goes further, protecting against discrimination based on race, sex (including gender identity or expression), sexual orientation, color, religion, marital status, familial status, ancestry, disability, age, and human immunodeficiency virus infection. A rent increase used to push out, or to avoid renting to, a member of any protected class is unlawful regardless of the notice given.
Source-of-Income and Voucher Protection
Hawaii also protects source of income. A state law effective May 1, 2023 (Act 310, codified at Hawaii Revised Statutes chapter 368F) makes it unlawful to refuse to rent, or to impose different terms, because a tenant participates in a housing-assistance program such as the Section 8 Housing Choice Voucher. The protection applies to landlords who own more than four rental units, with some exemptions, and violations carry fines. Using a rent increase to price out a voucher holder can therefore violate both this source-of-income law and the federal Fair Housing Act.
Consistency is your best defense
Increases applied evenly across comparable units on a regular schedule are far easier to defend than a one-off raise aimed at a single household. A selectively applied hike — or one that lands right after a complaint or that targets a voucher tenant — invites both a retaliation defense and a fair-housing claim, even though Hawaii sets no dollar cap. Treat every tenant the same and keep records of why each increase was made.
Takeaway
A Hawaii increase is unlawful if it is discriminatory under the federal Fair Housing Act or Hawaii Revised Statutes chapter 515, or if it targets a lawful source of income such as a Section 8 voucher under the 2023 law that covers landlords owning more than four units. Apply increases consistently and document the reason.
Emergency Rent Freezes
One more limit can appear without warning. Hawaii’s emergency-management law, Hawaii Revised Statutes chapter 127A, allows the Governor or a county mayor to restrict price increases — including rent — during a declared state of emergency. When such a proclamation is in force for an area, it can override the ordinary no-cap rule and temporarily freeze or limit rents there.
This is not theoretical. After the 2023 Maui wildfires, emergency proclamations restricted rent increases in the affected communities to protect displaced residents from price gouging. Outside a declared emergency, no statewide freeze applies. Before raising rent on a property in an area touched by a hurricane, flood, wildfire, or other disaster, check whether an active emergency proclamation covers it — a raise that violates a proclamation can carry penalties well beyond an ordinary notice defect.
Takeaway
During a declared emergency, an emergency proclamation under Hawaii Revised Statutes chapter 127A can freeze or limit rents in the affected area, overriding the no-cap default. Confirm no active proclamation covers the property before you raise the rent.
The Hawaii Landlord Playbook
Put the whole framework into a repeatable sequence and a rent increase becomes routine instead of risky. Follow these steps every time.
Confirm your authority to raise rent now
Check the tenancy type. On a fixed-term lease you generally cannot raise rent mid-term without a lease clause; wait for renewal or use a lawful month-to-month process.
Check for any cap, ordinance, or emergency freeze
Hawaii has no statewide cap, but confirm no county rent-control ordinance and no active emergency proclamation limits the increase for the property’s island.
Screen the timing for retaliation
Make sure the increase is not landing shortly after a repair request or a health or code complaint. If it is near protected activity, document the legitimate market reason first.
Serve the correct written notice
Give at least 45 consecutive days for a month-to-month tenancy, or 15 days for a shorter period, under section 521-21. State the current rent, new rent, and effective date in writing, and count the days from delivery.
Document everything
Keep a copy of the notice, the proof of delivery, and a note of the market and cost reasons behind the increase. Consistent, documented, on-schedule increases are the ones that hold up.
Need the notice itself?
A ready-to-fill notice keeps the required fields in place. See our free Hawaii rent increase notice form, and the Hawaii lease agreement form if you need a fresh renewal term or a clause that addresses mid-term changes. Always tailor the numbers to your unit and verify current law.
Common Scenarios, Quickly Answered
✓ Usually Defensible
- Month-to-month raise with 45-day notice. A written notice served at least 45 consecutive days before the effective date, counted from delivery.
- Renewal increase. A negotiated new rent when a fixed term ends, delivered with proper notice for the going-forward tenancy.
- Market reset at turnover. Setting a new market rent for a new tenant after the prior one moves out.
- Consistent annual adjustment. The same schedule applied across comparable units with documented reasons.
✕ Likely Unlawful
- Mid-term hike, no clause. Raising rent during a fixed lease with no clause that permits it.
- Short notice. A month-to-month increase served with fewer than 45 consecutive days before the effective date.
- Post-complaint increase. A raise issued soon after a repair request or code complaint — presumptively retaliatory under section 521-74.
- Verbal or targeted. A spoken or texted increase, or one aimed at a protected class or a voucher tenant.
Rent Increases Go Smoother With the Right Tenant
The tenants who fight every lawful increase are often the ones who show red flags on screening. Comprehensive credit, income, and eviction-history reports catch the mismatch before you ever sign a lease.
Frequently Asked Questions
How much can a landlord raise the rent in Hawaii?
There is no statewide cap on the dollar amount or percentage of a rent increase in Hawaii. The state has no rent control, so a landlord may set a lawful increase at any amount the market will bear, as long as the correct written notice is given, the increase is not raised in the middle of a fixed-term lease without lease authority, and it is not retaliatory or discriminatory. No Hawaii county has enacted rent control; any county ordinance would rest on the county’s own powers, and Hawaii Revised Statutes section 666-20 only preserves an existing emergency rent-control ordinance from being overridden by the landlord-tenant code rather than granting counties that power. As of 2026 none impose a cap. During a declared state of emergency, an emergency proclamation can temporarily restrict rent increases. Verify current state and county law before you set an increase.
How much notice must a Hawaii landlord give before raising rent?
Under Hawaii Revised Statutes section 521-21, a landlord may not increase the rent on a month-to-month tenancy without giving the tenant at least 45 consecutive days written notice before the effective date of the increase. For a tenancy shorter than month to month, such as a week-to-week tenancy, at least 15 consecutive days written notice is required. A verbal announcement, a text, or an email the tenant never agreed to accept is not proper notice and does not start the 45-day clock.
Can a landlord raise the rent in the middle of a lease in Hawaii?
Generally no. During a fixed-term lease the rent is locked at the agreed amount for the whole term unless the lease itself contains a clause that expressly permits a mid-term increase. A landlord may raise the rent when the fixed term ends and the parties negotiate a renewal, or on a month-to-month tenancy by serving the required 45-day written notice under Hawaii Revised Statutes section 521-21. Absent a lease clause, the tenant is entitled to the agreed rent through the end of the term.
Does Hawaii have rent control?
No. Hawaii has no statewide rent-control statute and no statewide cap on how much rent may rise. no Hawaii county has adopted rent control, and Hawaii Revised Statutes section 666-20 is only a savings clause that preserves an existing emergency rent-control ordinance from being overridden by the landlord-tenant code, not an affirmative grant of county rent-control power, so most rentals are free-market subject only to the notice, anti-retaliation, and fair-housing rules. Rent-control bills are proposed periodically in the Legislature, and an emergency proclamation can freeze rents during a declared emergency, so confirm the current status for the property’s island and county.
How much notice must a tenant give to end a month-to-month tenancy in Hawaii?
Under Hawaii Revised Statutes section 521-71, a tenant on a month-to-month tenancy must give the landlord at least 28 days written notice before the intended termination date, and remains responsible for rent through the 28th day. A landlord ending a month-to-month tenancy must give the tenant at least 45 days written notice. This matters after a rent increase because a tenant who does not want to pay the new rent can serve a 28-day notice and move out rather than accept the raise.
Can a Hawaii landlord raise rent in retaliation?
No. Hawaii Revised Statutes section 521-74 prohibits a landlord from demanding a rent increase, recovering possession, decreasing services, or causing the tenant to quit involuntarily in retaliation after the tenant has, in good faith, complained to the landlord or a government agency such as the Department of Health or the Office of Consumer Protection about a code or health violation, or requested repairs under sections 521-63 or 521-64. When an increase follows soon after protected activity, courts generally treat conduct within about a year of the complaint as presumptively retaliatory, shifting the burden to the landlord to prove a legitimate reason. A tenant who is unlawfully dispossessed may recover damages, costs, and reasonable attorney’s fees.
Is there a limit on rent increases during a state of emergency in Hawaii?
There can be. Hawaii’s emergency-management law, Hawaii Revised Statutes chapter 127A, lets the Governor or a mayor restrict price increases, including rent, during a declared state of emergency. After the 2023 Maui wildfires, for example, emergency proclamations limited rent increases in the affected area. Outside a declared emergency there is no statewide cap. Check whether an active emergency proclamation covers the property before raising rent.
Can a Hawaii landlord refuse a Section 8 voucher or raise rent to avoid one?
Generally no, for covered landlords. A Hawaii law effective May 1, 2023 prohibits source-of-income discrimination, making it unlawful to refuse to rent, or to set different terms, because a tenant uses a Section 8 Housing Choice Voucher or other rental assistance. The protection applies to landlords who own more than four rental units, with some exemptions. Using a rent increase to push out a voucher holder can violate both this law and the federal Fair Housing Act, so treat voucher tenants the same as any other applicant.
What makes a Hawaii rent increase notice valid?
A defensible notice is in writing and states the tenant’s name and the property address, the current rent, the new rent, and the effective date, and it gives at least the full 45 days required for a month-to-month tenancy under Hawaii Revised Statutes section 521-21, counted from proper delivery. Serve it by a provable method such as certified mail or personal delivery with a signed acknowledgment, and keep a copy of both the notice and the proof of delivery. A spoken or texted increase does not satisfy the statute.
Can a rent increase be illegal even though Hawaii has no cap?
Yes. Even with no dollar cap, a Hawaii rent increase is unlawful if it uses the wrong notice period, is imposed mid-term without lease authority, is retaliatory under Hawaii Revised Statutes section 521-74, is discriminatory against a protected class under the federal Fair Housing Act or Hawaii Revised Statutes chapter 515, targets a lawful source of income such as a Section 8 voucher, or violates an active emergency proclamation. The absence of a cap limits the amount question, not the how and why questions.
What is the safest way for a landlord to raise rent in Hawaii?
Confirm you have the right to raise rent now, at renewal or on a month-to-month tenancy and never mid-term without a lease clause, then serve a clear written notice giving at least the full 45 days required by Hawaii Revised Statutes section 521-21 by a provable method. Avoid timing the increase right after a repair request or complaint, apply increases consistently, check for any active emergency proclamation or county ordinance, and keep a copy of the notice and proof of delivery. A documented, on-schedule increase is the one that holds up.
