Show smoke/CO upgrades: Most residential additions in Groton require updating alarms throughout the home. Address egress and safety: Bedrooms need proper egress windows, and garage conversions must address fire separation. Energy compliance matters: Show U-factors for windows, R-values, and mechanical efficiency on your plans. Document existing conditions: Photos and basic as-builts can clarify tie-ins for home expansion services. Communicate with neighbors: Especially for tight setbacks or staging needs. Choose the right team: A general contractor for additions with local experience reduces plan review cycles and inspection issues.

Special Considerations: Garage Conversions and Second Stories Garage conversion Groton projects

Fire separation: Maintain the required fire-rated assemblies between garage and living space if any portion remains a garage.

Parking: Zoning may require maintaining a minimum number of off-street spaces.
