Boston's Rental Property Rules: The Rules That Matter

Every city handles rental property rules a little differently. In Boston, Massachusetts, there are 11 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Security Deposit Rules

MGL Ch. 186 §15B caps Boston security deposits at one month's rent, requires interest-bearing escrow in a Massachusetts bank, mandates written receipts, and triggers triple damages if a landlord commingles funds or fails to return deposit within 30 days of tenancy end.

Key details: Citation: MGL Ch. 186 §15B. Deposit cap: One month's rent. Return deadline: 30 days post-tenancy. Penalty: Triple damages plus fees. Annual interest: 5% or bank rate.

Commingling, missing receipts, late return, or unitemized deductions trigger automatic triple damages plus attorney fees. The penalty applies even for technical paperwork errors.

Compared to other cities, Boston takes a harder line on security deposit rules. The enforcement and penalty structure reflects that.

No-Fault Evictions

Massachusetts allows no-fault termination of tenancies-at-will with 30 days or full rental period notice under MGL Ch. 186 §12. Boston has no local just-cause eviction ordinance, though a Home Rule petition for tenant protections remains pending state approval.

Key details: Citation: MGL Ch. 186 §12. Notice required: 30 days minimum. Boston just-cause: Not currently in effect. Court process: Summary process required.

Self-help eviction, lockouts, utility shutoffs, or removing tenant belongings without a court order trigger MGL Ch. 184 §18 penalties of three months' rent plus attorney fees.

Section 8 Voucher Acceptance

The Boston Housing Authority (BHA) administers the federal Section 8 Housing Choice Voucher program and the state Massachusetts Rental Voucher Program (MRVP). Landlords must pass HUD Housing Quality Standards inspection and execute a HAP contract before BHA will subsidize rent.

Key details: Administering agency: Boston Housing Authority. Inspection standard: HUD HQS. Lead paint trigger: Pre-1978 buildings. MA voucher program: MRVP, AHVP.

Charging the voucher tenant more than the approved tenant share, side payments, or unauthorized lease addenda violate the HAP contract and federal law.

Tenant Anti-Harassment

MGL Ch. 184 §18 and Ch. 186 §14 prohibit landlords from using lockouts, utility shutoffs, threats, or harassment to force tenants out. Violations carry treble damages, attorney fees, and possible criminal liability under Boston housing court enforcement.

Key details: Civil penalty: Treble damages. Criminal penalty: Up to six months jail. Citation: MGL Ch. 186 §14. Lockout statute: MGL Ch. 184 §18.

Shutting off heat in winter, changing locks, removing doors, or threats designed to force a tenant out trigger criminal penalties plus three-times-rent civil damages.

This is one of the stricter rules in Boston's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Eviction Moratorium History

Massachusetts enacted the nation's strictest pandemic eviction moratorium under Ch. 65 of the Acts of 2020, expiring October 2020. A subsequent state law preserved continuance protections through 2024. Boston tenants today rely on the standard summary process and Right to Counsel pilot.

Key details: State moratorium: Apr-Oct 2020. Statute: Ch. 65, Acts of 2020. Continuance protections: Ch. 257, Acts of 2020. Boston RTC pilot: Launched 2024.

Filing or prosecuting an eviction in violation of an applicable moratorium during its effective period exposed landlords to penalties under MA consumer-protection law (Ch. 93A).

Source-of-Income Discrimination

Massachusetts MGL Ch. 151B §4 prohibits Boston landlords from refusing tenants based on use of housing subsidies including Section 8, MRVP, or veterans' benefits. Source-of-income discrimination is a civil rights violation enforced by the MA Commission Against Discrimination.

Key details: Citation: MGL Ch. 151B §4(10). Enforcing agency: MCAD. Building threshold: Three or more units. Damages: Plus attorney fees.

Refusing applicants because they hold a voucher, advertising 'no vouchers,' or applying income tests that disqualify subsidized tenants violates state civil rights law.

This is not one of those rules that cities tend to ignore. Boston actively enforces its source-of-income discrimination requirements.

Relocation Assistance

Boston has no general relocation-assistance ordinance for displaced tenants. Limited statutory rights apply for code-condemned units (MGL Ch. 79A) and federally funded relocations (Uniform Relocation Act). The 2024 Home Rule petition seeking broader tenant protections remains pending.

Key details: General requirement: None statewide. Condemnation statute: MGL Ch. 79A. Federal trigger: Uniform Relocation Act. Boston ordinance: Pending Home Rule petition.

Failing to provide statutorily required Ch. 79A or URA payments after a public-action displacement is grounds for a tenant claim plus interest and attorney fees.

Boston is more permissive than most cities when it comes to relocation assistance. That said, there are still limits.

Council District Preference

Boston's Inclusionary Development Policy and BHA waitlists apply local-preference points for current Boston residents and city employees. HUD requires preferences to be applied without disparate-impact discrimination, periodically reviewed under fair-housing reporting.

Key details: Authority: BPDA IDP, BHA. Preference categories: Resident, worker, veteran. Federal oversight: AFFH 2020 settlement. Lottery system: MetroList Boston.

Preference policies that produce significant disparate impact on a protected class without legitimate justification can violate the Fair Housing Act and state Ch. 151B.

Just Cause Eviction

Massachusetts does not have a statewide just cause eviction law, and Boston does not have a local just cause ordinance. Landlords may decline to renew tenancies with proper notice. However, evictions require court proceedings, and tenants have procedural protections under MGL c.239 (summary process). Retaliatory and discriminatory evictions are prohibited.

Key details: Just Cause Required: No — not in Boston or MA. Notice Period: 30 days for month-to-month. Court Process: Required for all evictions (MGL c.239). Retaliation Ban: MGL c.186 §18. Self-Help Eviction: Illegal — treble damages.

Self-help evictions (lock changes, utility shutoffs) are illegal and carry treble damages under MGL c.186 §14. Retaliatory evictions carry penalties including costs and attorneys' fees. Eviction without proper court process is void. Landlords face contempt of court for violating eviction procedures.

Rent Control

Massachusetts banned municipal rent control statewide through a 1994 ballot initiative (Question 9). Boston, which previously had rent control since 1970, cannot regulate rents or impose rent stabilization measures. There are no caps on rent increases for market-rate units in Boston.

Key details: Status: Banned statewide since 1994. State Law: MGL c.40P — Question 9 (1994). Previous Control: 1970–1997 in Boston. Decontrolled Units: ~28,000 in Boston. Rent Increase Limit: None — market rate.

Not applicable — there are no rent control provisions to violate in Boston. Landlords may raise rents by any amount with proper notice (30 days for month-to-month tenancies). Discriminatory rent increases may violate fair housing laws.

Boston is more permissive than most cities when it comes to rent control. That said, there are still limits.

Rental Registration

Boston requires all rental properties to be registered with the Inspectional Services Department. Owners must obtain a Certificate of Occupancy and comply with the state sanitary code (105 CMR 410). Multi-unit residential buildings require regular ISD inspections. Boston's rental registration helps track housing conditions and enforce code compliance.

Key details: Registration: Certificate of Occupancy required. Heat Standard: 68°F minimum Sept 15–June 15. Inspections: Proactive for multi-unit buildings. Property Manager: Required for 6+ unit buildings. Lead Paint: Abatement required with children under 6.

Operating rental units without a Certificate of Occupancy carries fines up to $300 per day. Sanitary code violations must be corrected within the timeframe specified by ISD — emergency conditions (no heat, no water) require immediate response. Lead paint violations carry fines up to $1,000 per day. Failure to register carries escalating fines.

This is not one of those rules that cities tend to ignore. Boston actively enforces its rental registration requirements.

The Bottom Line

Boston is tougher than many cities when it comes to rental property rules. Out of the 11 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Boston, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

Keep in mind that Boston can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
