Before You Build in Weymouth, MA: Permit & Rule Checklist (2026)

In Weymouth, fences 6 feet and under do not require a building permit. Fences over 6 feet require a permit from the Building Department. Pool enclosure fences always require a permit.

Massachusetts General Law Chapter 49 §21 governs shared fence obligations between neighbors. Weymouth does not have a specific local fence neighbor-dispute ordinance. Disputes about fence placement require a property survey.

Weymouth requires a building permit for fences over 6 feet. Fences and plantings within 30 feet of a corner street intersection may not exceed 3 feet above curb level (Zoning §120-46). Commercial/industrial property fences abutting residential uses must be at least 5 feet high.

Private swimming pools in Weymouth are accessory uses in residential districts and must conform to all zoning yard setback requirements. Building permits are required for pools over 24 inches deep. MA Building Code (780 CMR) and state sanitary code apply.

Above-ground pools in Weymouth over 24 inches deep require a building permit and must meet the same zoning setback and barrier requirements as in-ground pools. Shallow portable pools are generally exempt.

Weymouth pool fencing must comply with Massachusetts Building Code (780 CMR) — minimum 48-inch (4-foot) barrier height. Gates must be self-closing and self-latching with latches at least 54 inches above ground. Pool enclosure fences require a building permit.

Weymouth Town Council passed ADU Ordinance Amendment (Measure 24-119) adding Article 29 to Chapter 120. ADUs are allowed by right on single-family lots up to 900 sq ft or 50% GFA. Lots under 5,000 sq ft are ineligible.

Garage conversions to ADUs in Weymouth are permitted under the 2025 ADU ordinance (Article 29). Conversions require a building permit, Site Plan Approval, and design review. The converted ADU must comply with the 750–900 sq ft size limit and setback requirements.

Weymouth treats carports more flexibly than most accessory structures. Under Weymouth Code § 120-54 (Confinement of accessory uses to rear yard), private garages and carports are explicitly exempted from the general rule that accessory uses must be confined to the rear yard - though they still may not be placed within the required front yard setback. Permits are issued by the Department of Municipal Licenses and Inspections under 780 CMR (Massachusetts State Building Code, Tenth Edition), and dimensional standards in Article XV of Chapter 120 control side and rear setbacks.

Weymouth's zoning ordinance requires accessory structures (other than private garages) to be located in the rear yard. A one-story accessory structure may be built no closer than 5 feet to a side or rear lot line.

Weymouth is not on the Massachusetts year-round open burning ban list. Open burning is permitted seasonally with a $25 permit from the Weymouth Fire Department. Season runs January 15 to May 1; burning hours are 10 AM–4 PM with daily authorization required.

Fire pits in Weymouth used for non-cooking purposes are subject to MassDEP open burning rules and require a seasonal fire department permit. Cooking fires have more flexibility. Burning clean, dry firewood is required; trash burning is prohibited.

Weymouth does not have a comprehensive private-property tree trimming ordinance. Property owners must maintain trees to prevent hazards to public ways. The Weymouth Conservation Commission regulates work near wetlands under MGL c. 131 §40.

Weymouth is served by the MWRA regional water system. During MassDEP drought declarations, mandatory outdoor watering restrictions apply. No permanent year-round odd/even watering schedule was found in Weymouth's published code.

Weymouth does not have a comprehensive private-property tree removal permit ordinance. Removal near wetlands (within 100 feet) requires Conservation Commission review. Public shade tree removal requires Tree Warden approval.
