Security Deposit Limits in Massachusetts
Maximum amount landlords can collect
Under Massachusetts law, the maximum security deposit landlords can collect is 1 month rent. Maximum security deposit is 1 month’s rent. Last month’s rent (in addition to deposit) may also be collected but must earn interest.
- Standard Limit: 1 month
- Details: Maximum security deposit is 1 month’s rent. Last month’s rent (in addition to deposit) may also be collected but must earn interest.
- Legal Reference: MA Gen Laws ch. 186, § 15B
Before becoming a landlord or screening tenants, understanding deposit limits is essential for legal compliance. Overcharging can expose you to liability and tenant lawsuits.
While you’re allowed to charge up to 1 month, consider the local rental market. Setting deposits too high may deter qualified applicants, while setting them too low doesn’t adequately protect your investment. Most landlords find 1-1.5 months’ rent strikes the right balance.
🔍 Screen Tenants Before Collecting Deposits
The best protection isn’t a larger deposit—it’s finding responsible tenants. Our comprehensive screening includes credit, criminal, and eviction history.
Collecting Security Deposits
Best practices for move-in
When collecting security deposits in Massachusetts, follow these best practices to protect yourself and comply with state law:
Move-In Documentation
Document the property’s condition thoroughly before the tenant moves in. This creates a baseline for comparison when evaluating damage at move-out.
📋 Move-In Checklist for Massachusetts Landlords
- Complete a detailed move-in inspection with the tenant
- Take date-stamped photos of every room
- Note any existing damage or wear on inspection form
- Have tenant sign the inspection report
- Provide tenant with a copy of the inspection
- Document all appliance conditions and serial numbers
- Test smoke detectors and note results
- Record utility meter readings
- Provide written receipt for security deposit
- Store copies of all documents securely
Receipt Requirements
Provide tenants with written documentation of their security deposit payment, including the amount paid, date received, and where the funds will be held.
Under Massachusetts law (MA Gen Laws ch. 186, § 15B), landlords must:
- Accept payment via check, money order, or cashier’s check
- Provide written receipt upon request
- Include deposit amount in the lease agreement
- Follow any local ordinances that may impose additional requirements
Holding Requirements
How to properly store deposits
Interest required at 5% per year OR the actual interest earned (whichever is greater). Must be paid annually and at end of tenancy.
Interest required at 5% per year OR the actual interest earned (whichever is greater). Must be paid annually and at end of tenancy.
Massachusetts requires landlords to hold security deposits in a separate account. Do not commingle deposit funds with your personal or operating accounts.
Best Practices for Holding Deposits
- Keep deposits in a dedicated account separate from operating funds
- Maintain clear records of each tenant’s deposit amount
- Track any interest earned if required by law
- Never use deposit funds for personal expenses or property operations
- Keep documentation accessible for end-of-tenancy accounting
Allowable Deductions
What you can and cannot deduct
Massachusetts landlords may deduct from security deposits for legitimate reasons, but cannot charge tenants for normal wear and tear. Understanding the difference is crucial to avoid disputes.
✅ Allowable Deductions
- Unpaid rent or late fees
- Damage beyond normal wear and tear
- Cleaning to restore unit to move-in condition
- Unpaid utility bills (if landlord-paid)
- Unreturned keys or access devices
- Damaged or missing appliances
- Unauthorized alterations
- Early termination fees (if in lease)
❌ Normal Wear and Tear (Cannot Deduct)
- Faded paint or wallpaper
- Worn carpet in high-traffic areas
- Small nail holes from pictures
- Minor scuffs on walls
- Worn finishes on floors
- Loose door handles or hinges
- Faded window treatments
- Minor plaster cracks
Calculating Depreciation
When deducting for damaged items, consider depreciation. You generally cannot charge full replacement cost for items that were already partially worn.
If carpet has a 10-year lifespan and was 6 years old when damaged:
- Replacement cost: $1,500
- Remaining useful life: 4 years (40%)
- Maximum deduction: $600 (40% × $1,500)
Charging the full $1,500 would be improper and could expose you to penalties.
Before making deductions, review our guide on verifying tenant income upfront—proper screening helps you find tenants who will maintain your property.
🛡️ Avoid Deposit Disputes with Better Screening
Most deposit disputes stem from renting to the wrong tenants. Comprehensive screening reveals fake references and fraudulent income before they become your problem.
