Garage conversion rules in Washoe County, NV — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage or accessory structure into livable space turns it into a dwelling unit subject to the county's ADU rules. Installing both a kitchen and a toilet automatically makes it a dwelling unit.
Washoe County treats a converted garage as an accessory dwelling once it contains independent living facilities. Under WCC 110.306.10(h), installing both a kitchen (as defined in Article 902) and a toilet in a detached accessory structure renders it a dwelling unit subject to Article 306's ADU standards. Any detached accessory structure connected to water or sewer must record a deed restriction stating it will not be converted to an ADU unless legally permitted. An attached ADU may be created by converting part of an existing single-family dwelling (Sec. 110.306.20(e)), but any exterior entrance to the ADU cannot share the same wall as the main entrance. City of Reno/Sparks conversions follow municipal codes.
Unpermitted conversions creating an unauthorized dwelling unit are code violations under Article 910 and may require removal of kitchen/plumbing or ADU permitting.
