Full Breakdown
Raleigh's Unified Development Ordinance treats the Tiny House as its own residential building type under Sec. 8, not merely an accessory shed. The definition caps a Tiny House at an 800-square-foot building footprint and 1,200 square feet of gross floor area, built to hold one or two principal dwelling units on a single lot; a series of tiny homes may also be grouped as a cottage court on one lot. Minimum lot size scales with the residential district: 40,000 square feet in R-1, 15,000 in R-2, 7,500 in R-4, 3,000 in R-6, and just 2,000 square feet in R-10 -- a twenty-fold range across the same building type.
Lot width minimums run from 100 feet in R-1 down to 25 feet in R-10, and lot depth from 100 feet down to 45 feet. Principal building setbacks also shrink by district, from 20 feet off the primary street in R-1/R-2/R-4 to 10 feet in R-6/R-10, and 30 feet off the rear line in R-1 through R-4 versus 10 feet in R-6/R-10. Height is uniform: 26 feet or two stories in every district. When a Tiny House serves as an accessory structure rather than the principal dwelling itself, Sec.
C sends the setback question to the general accessory-structure table in Sec. 2, which sets a 5-foot minimum from side and rear lines for small structures and a 6-foot separation from other buildings on the same lot. A manufactured home can qualify as a Tiny House only if it carries a roof pitch of at least 5:12, eave projections of at least 10 inches, first-story exterior walls at least 7 feet 6 inches tall, non-reflective siding, code-compliant foundation skirting, and a gross floor area no larger than 600 square feet.
Violations & Fines
Development Services and the Zoning Administrator enforce Tiny House standards through the UDO's general civil-penalty process at Sec. 10.4.2: a UDO violation carries a $100 civil penalty unless a higher amount applies elsewhere, with continuing violations penalized separately, and unpaid citations converted to a civil debt action. Criminal violations remain a misdemeanor under N.C. Gen. Stat. § 14-4.
