Garage conversion rules in Babylon, NY — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions to habitable space require a Babylon building permit, zoning review, and compliance with NY State Residential Code for habitable rooms (ceiling height, egress, insulation, HVAC, smoke/CO alarms). Converting a garage often requires replacing required off-street parking with an alternative space. Unpermitted conversions are a common code enforcement target.
Town zoning typically requires two off-street parking spaces per dwelling; removing a garage eliminates those spaces unless replaced. Illegal garage conversions create safety hazards and are frequent complaint source. Legal conversion requires building permit, electrical permit, plumbing permit if added, egress windows, proper insulation, and final certificate of occupancy amendment. Suffolk County Health Department approval needed if bathroom or bedroom added and property is on septic.
Illegal conversion: fines $500-$5,000, stop-work order, order to restore garage or obtain permits. May trigger tax assessment increase.
