Tiny home rules in Delaware County, PA — 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.
Delaware County sets no tiny-home rule. Whether a tiny house on a foundation is allowed is decided by your municipality's zoning ordinance, and it must meet the Pennsylvania Uniform Construction Code. Movable tiny homes on wheels are usually treated as RVs.
There is no county tiny-home ordinance. Under the PA Municipalities Planning Code (§603), each borough or township zoning ordinance controls minimum dwelling size, lot requirements, and whether a tiny house is a permitted principal or accessory dwelling. A tiny home on a permanent foundation must also comply with the Pennsylvania Uniform Construction Code (which in 2018 adopted the IRC Appendix Q tiny-house standards) and requires local building permits. A tiny house on wheels is typically classified as a recreational vehicle and cannot be used as a permanent dwelling unless zoning specifically allows it. Confirm both zoning and building-code treatment with your municipality.
Occupying an unpermitted tiny home, or one not allowed by local zoning, can bring zoning enforcement, a UCC order, and fines set by the municipality.
