Garage conversion rules in Oro Valley, AZ β sometimes called garage-to-ADU or accessory living unit conversions β govern permits, ceiling height, egress, and parking replacement.
Oro Valley requires a building permit for garage conversions. Converted garages must meet IRC habitability standards, and off-street parking minimums must still be satisfied.
Converting an attached or detached garage to living space in Oro Valley requires a building permit from the Town Development Services Department. The conversion must comply with the International Residential Code as adopted by the Town, including minimum ceiling height of 7 feet, natural light equal to 8 percent of floor area, and emergency egress windows in bedrooms. Electrical, plumbing, and HVAC upgrades must meet current code. The Zoning Code requires a minimum of two off-street parking spaces per single-family dwelling, so converting a two-car garage typically requires adding a compliant driveway pad or carport to maintain required parking. HOA CC&Rs in most Oro Valley subdivisions impose additional restrictions or outright prohibit garage conversions, particularly in communities governed by the Vistoso, Rancho Vistoso, and Sun City architectural review committees.
Work without a permit may result in a stop-work order, fines up to $2,500 per day of violation, and mandatory reversal of unpermitted construction. HOA violations may trigger separate fines and lien authority.
