Garage conversion rules in Rochester, NY — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions to living space in Rochester require a building permit and must meet NYS Residential Code standards. The property must maintain required off-street parking after the conversion. If creating a separate unit, ADU regulations apply.
Converting a garage to habitable space requires a building permit and must comply with the NYS Residential Code. Requirements include minimum ceiling height, egress windows, insulation, electrical, plumbing, and HVAC. The garage door must be properly enclosed. Off-street parking requirements for the property must still be met after conversion. If the conversion creates a separate dwelling unit, it must comply with ADU and zoning regulations.
Unpermitted garage conversions face fines of $500–$2,000, mandatory permit acquisition (double fees), and may need to be restored to garage use if code requirements cannot be met.
