The Rear Addition That Needed More Than a Building Permit
A contractor signs a fixed-price contract to build a 14 ft x 22 ft one-story family-room addition on the rear of a 1958 ranch in a Massachusetts R-1 district. The lot is 9,000 sf. Zoning requires a 25 ft rear setback and 30% maximum lot coverage. The existing house covers 27.5% of the lot and its rear wall stands 32 ft from the rear lot line, so the addition would leave 18 ft of rear yard and raise coverage to about 30.9%. The town's building inspector reviewed a plot plan and issued the building permit. Three weeks later, after footings were excavated, the abutting neighbor filed an appeal with the zoning board of appeals. The homeowner says the neighbor 'always does this' and wants the crew to keep framing.
1. Was the building permit the only approval this project needed? Identify the relief required, the deciding body, and the findings the applicant would have to make.

No. A building permit is a construction-code approval (780 CMR); zoning compliance is a separate determination, and the inspector's issuance of the permit is itself a zoning decision that can be appealed.
Two dimensional nonconformities are created:
- Rear setback: 18 ft where 25 ft is required.
- Lot coverage: 30% of 9,000 sf = 2,700 sf cap. Existing = 2,475 sf. The 308 sf addition lands at 2,783 sf - 83 sf over.
The relief is a dimensional variance from the ZBA (MGL c.40A, s.10), which requires findings that (1) special circumstances relate to soil conditions, shape, or topography of the lot, (2) literal enforcement would be a substantial hardship, financial or otherwise, and (3) the relief can be granted without substantial detriment to the public good and without nullifying the zoning intent.
Reasoning check: the hardship here is self-created - the owner is choosing a larger addition on an already near-cap lot - which is the classic weak variance case. Note also that the c.40A, s.6 protection for pre-existing nonconforming structures only covers alterations that do not increase the nonconformity; this increases both.
Practical fix: coverage is solvable by design - a 14 ft x 16 ft footprint (224 sf) lands at 2,699 sf, just under the cap. The setback cannot be solved without moving the footprint, so the real choice is redesign versus variance.
2. What is the status of the permit and the work while the appeal is pending, and what must the contractor do about the open footing excavation?
Read the worked answer
An aggrieved person may appeal the building inspector's decision to the ZBA within 30 days of the permit's issuance (MGL c.40A, s.15). Filing the appeal does not by itself revoke the permit, but the ZBA may annul it after hearing - so continuing to frame means the contractor proceeds at risk of a stop-work order and removal of work.
Separate and non-negotiable: the open excavation is a safety and property-protection problem that does not wait for the zoning process. It must be barricaded and either backfilled, covered with rated plates, or otherwise stabilized, especially with an abutting neighbor now actively hostile and inspecting.
Business judgment:
- Read the contract for who bears the risk of obtaining zoning and permit approvals. Absent a clause, approval risk generally sits with the owner, but the contractor must give written notice and get written direction to stop or proceed.
- If the contractor is directed to stop, document standing time, equipment, and demobilization for a delay claim; if directed to proceed, confirm that direction in writing.
- Do not let the homeowner's assurance substitute for a decision by the ZBA.
3. The ZBA grants the variance. What happens next, and what deadline governs when the contractor can safely start building?
Read the worked answer
The variance decision must be filed with the town clerk, and it is not final until the appeal period runs: a ZBA decision may be appealed to the Land Court or Superior Court within 20 days after filing with the town clerk (c.40A, s.17). Building before that runs - and before any conditions in the decision are satisfied - is the same risk as before.
Sequence the contractor should follow:
- Obtain a copy of the filed decision and read every condition (planting screens, drainage, height limits, as-built survey requirements).
- Confirm the 20-day appeal window has expired with no appeal filed, or obtain counsel's written clearance.
- Confirm the building permit is still valid and matches the approved footprint; if the footprint changed during the process, the permit must be revised before construction resumes.
- Calendar the variance's exercise deadline - rights authorized by a variance typically lapse if not exercised within a year, with a limited extension available from the board.
The estimate and schedule should be rebaselined for the delay, and the excavation that sat through the appeal should be re-inspected before footings are poured.
