Short-Term Rentals in Brookline, MA: What Residents Actually Need to Know

If you live in Brookline or are thinking about moving there, short-term rentals are one of those things you probably won't think about until they affect you directly. Brookline has 6 specific rules on the books covering different aspects of short-term rentals, and some of them might surprise you.

Occupancy Limits

Brookline's Short-Term Rental General By-Law (Article 17, approved at the May 2021 Annual Town Meeting) caps overnight occupancy at 2 guests per bedroom up to a maximum of 8 guests, and any occupancy above 3 persons not within the second degree of kindred to the operator must comply with State Building and Sanitary Code requirements for sleeping-room occupancy, ventilation, egress, and life-safety devices.

Key details: Bylaw: Article 17 (Town Meeting 2021). Per-Bedroom Cap: 2 guests per bedroom. Overall Cap: 8 guests maximum. Unrelated Threshold: Above 3 must meet state/local code. Annual Day Cap: 90 days (180 by Select Board).

Renting to more than 2 guests per bedroom or to more than 8 guests total violates Article 17 and is enforced by the Town's Inspectional Services / STR inspection team. Operating without a current Certificate of Registration, exceeding the 90-day (or Select Board-approved 180-day) annual cap, or hosting unrelated occupants beyond 3 without code-compliant sleeping rooms can lead to fines, suspension, modification, or revocation of the STR Certificate of Registration. Each day of violation may be treated as a separate offense.

Compared to other cities, Brookline takes a harder line on occupancy limits. The enforcement and penalty structure reflects that.

Insurance Requirements

Brookline Short-Term Rental General By-Law Article 17 requires every STR operator to notify their insurer that the unit is being used as a short-term rental and to maintain liability insurance of not less than $1,000,000, mirroring the statewide minimum imposed on STR operators under MGL c. 64G as amended by 2018 Mass. Acts c. 337.

Key details: Bylaw: Article 17. Liability Minimum: $1,000,000. State Backstop: MGL c. 64G / 2018 Mass. Acts c. 337. Insurer Notice: Required before listing. Certificate Fee: $275 (up to 5 yrs, non-transferable).

Operating an STR in Brookline without the Article 17 $1M liability minimum or without notice to the insurer is a bylaw violation. Combined with operating without a Certificate of Registration, the Town's STR inspection team and Inspectional Services Department may pursue fines, suspension, modification, or revocation of the Certificate. The Town may also notify the platform under MGL c. 64G enforcement provisions, which can result in delisting.

This is not one of those rules that cities tend to ignore. Brookline actively enforces its insurance requirements requirements.

Noise Rules

Short-term rental guests in Brookline are subject to all noise regulations under Article 8.15. No separate STR quiet hours exist; the background-noise-based limits and strong enforcement in this dense, progressive community apply to all occupants.
