Garage conversion rules in Pearl City, HI — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage into living space in Pearl City is treated as an ADU under the Land Use Ordinance, requires building permits, and usually requires replacement off-street parking.
ROH Sec. 21-5.720 treats garage-to-living-space conversions in Pearl City as accessory dwelling unit creation. Conversions must meet ADU standards including minimum lot size, replacement off-street parking for the displaced garage, and compliance with setback and height limits. Building permits are required under ROH Sec. 18-3.2. After-the-fact permit provisions are available for garage conversions completed before September 14, 2015 without permits. Because Pearl City lots are often smaller and near Pearl Harbor military housing, replacement parking is a common challenge.
Unpermitted garage conversions, failure to provide replacement parking, or short-term rental of converted space may trigger fines and abatement.
