Start Here: Boston ADU Zoning Checklist for Homeowners
Before you design or hire a contractor, align your plan with local requirements. Use this checklist to guide early decisions for an accessory structure or an added living unit.

Feasibility & Site Review Checklist
Run a feasibility pass before investing in detailed drawings. First, map your lot to evaluate required distances from property lines, structures, and easements.

Review existing trees, drainage patterns, and any shared boundaries that could affect grading Attached ADU Boston or foundation placement. Check utility capacity for water, sewer, and electrical service, and note whether upgrades are anticipated. If your plan involves expanding an existing structure, include a clear description of the addition area and how it integrates with ventilation, egress, and fire safety needs.

If your plan involves an attached unit, treat compliance as a design requirement, not an afterthought. Prepare for review of building code requirements, including egress pathways, smoke detection, and ceiling height or insulation considerations. Confirm that your layout supports safe circulation and bathroom placement, and that any shared walls meet required construction standards. Ensure your contractor understands documentation expectations, since consistent drawings reduce the chance of resubmittals. Compile proof for lot and dwelling details, plus contractor credentials where required. Address neighborhood fit by planning for exterior appearance, drainage control, and any alterations that affect parking or landscaping, so the final package reads as a complete, coherent project.
