Tiny home rules in Hendersonville, TN — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Tiny homes in Hendersonville must comply with the Tennessee-adopted 2018 IRC (including Appendix Q for dwellings 400 sq ft or less). A site-built tiny home on a permanent foundation is either the principal single-family dwelling (must meet zone's minimum lot size and principal-building setbacks) or an accessory dwelling subject to Ch. 10.4 ADU rules (30,000+ sq ft lot, CUP, family-only occupancy, 1,200-1,800 sq ft cap). Tiny homes on wheels classified as RVs or travel trailers cannot be used as a residence in residential zones. Tennessee does not preempt local tiny-home rules.
Hendersonville follows the Tennessee-adopted 2018 IRC, which incorporates IRC Appendix Q standards for dwellings 400 sq ft or less (minimum room sizes, ceiling heights, loft access by ladder or alternating-tread device, emergency escape and rescue openings, sleeping loft minimums). A site-built tiny home on a permanent foundation in a Hendersonville residential zone is either: (1) the principal single-family dwelling, in which case it must meet the dimensional standards of its zoning district under the Zoning Ordinance — typical lot/setback standards in Hendersonville's SR-1 and SR-2 districts include substantial minimum lot sizes (consult the Zoning Map and Ch. 10.3 for the specific district), front setbacks typically 30-40 ft, side setbacks 10-15 ft, and rear 20-30 ft, varying by district; or (2) an accessory dwelling subject to the full Accessory Dwelling rules in Ch. 10.4 — which require the lot be at least 30,000 sq ft, a Conditional Use Permit ($250) from the Board of Zoning Appeals, owner-occupancy, family-only occupancy, design matching the principal dwelling, 20-ft side/rear setbacks, and size caps from 1,200 sq ft (lots 30,001-43,559 sq ft) up to 1,800 sq ft (lots over 3 acres). Tiny homes on wheels (THOW) classified as RVs, travel trailers, or park model RVs cannot be used as a primary or accessory dwelling in residential zones — Hendersonville's Zoning Ord. and Codes Department treat RVs as vehicles, not dwellings. They may be stored on private property subject to applicable storage rules and HOA covenants but cannot legally be occupied as a year-round residence. Permanent placement of a manufactured/HUD-code tiny home requires the same building permit, foundation, anchorage, utility connections, and inspections as any single-family residence. Tennessee state law does NOT preempt local zoning of tiny homes (unlike, e.g., California's ADU laws). Hendersonville has not enacted a tiny-home overlay district or pocket-neighborhood ordinance as of 2026.
Living in an RV-classified tiny home in a residential zone is a Ch. 10 zoning violation enforceable by the Building Codes & Zoning Compliance office: order to vacate, city general penalty under Municipal Code § 1-407, and possible referral to Municipal Court. Building a site-built tiny home without permits triggers stop-work, IRC enforcement, and double permit fees.
