Summary
Rowan County lets a detached accessory dwelling unit be built inside a garage, workshop, or similar accessory structure rather than as a stand-alone building. County Code Sec. 21-56(1)d(3) still requires that structure to meet the accessory-structure setbacks in Sec. 21-285 and every other ADU standard in Sec. 21-56(1)d.
3.A detached accessory dwelling unit may be contained within a garage, workshop, or similar accessory structure. The accessory structure must comply with the setback standards in section 21-285.
Full Breakdown
The provision sits inside the same ADU standards discussed at Sec. 21-56(1)d, but subsection 3 addresses the specific case of building or converting a garage, workshop, or similar accessory structure into living space rather than a separate detached unit. Choosing that route does not exempt the structure from the county's accessory building rules: it still has to comply with the accessory-structure setback standards, which for the Rural Agricultural (RA) and Rural Residential (RR) districts require, per the Sec. 21-84 dimensional table, thirty feet from the front property line and ten feet from the side and rear yard for a garage-type accessory structure, plus the ADU-specific requirement in Sec.
21-56(1)d(6) that its setbacks match the principal dwelling's, whichever is more restrictive. The garage-turned-ADU still cannot exceed 1,000 square feet, must remain smaller than the main house, and counts as the property's one allowed ADU. A manufactured home converted into a detached garage-style structure does not qualify, since Sec. 21-56(1)d(4) bars manufactured homes from ADU status outright. As with any ADU, the converted structure needs a wastewater and water supply connection approved either by a municipality or the Rowan County Environmental Health Department before Planning & Development will sign off on the site plan required under Sec. 21-52.
Violations & Fines
A garage converted to living space without meeting accessory-structure setbacks, exceeding the 1,000-square-foot ADU cap, or lacking an approved wastewater and water connection is enforced the same way as any other zoning violation: a Sec. 21-13 notice of violation with a correction period, followed by escalating Sec. 21-14 civil penalties of $25.00, $50.00, and $100.00 for the first, second, and third citations, plus $100.00 per day thereafter.
