Summary
Montgomery County has no tiny-home rule. Whether a tiny house on a foundation is allowed depends on your borough or township zoning and minimum-dwelling standards, plus the statewide Uniform Construction Code. A tiny home on wheels is usually treated as an RV.
Zoning ordinances... may permit, prohibit, regulate, restrict and determine:... Size, height, bulk, location, erection, construction, repair, maintenance, alteration, razing, removal and use of structures.
Full Breakdown
The county does not zone residential land, so tiny-home legality is a municipal question under MPC Section 603(b), which lets local ordinances regulate 'size, height, bulk... and use of structures' and set minimum dwelling sizes and density. A tiny house on a permanent foundation must meet local zoning (lot size, setbacks, minimum floor area) and get a Pennsylvania Uniform Construction Code building permit. A tiny house on wheels is generally classified as a recreational vehicle and cannot be a permanent residence except where a municipality allows RV/park-model living. Confirm both the zoning classification and building-permit path with your borough or township before buying or building.
Violations & Fines
Placing or living in a tiny home that violates local zoning or lacks a UCC permit is a municipal violation; the borough or township can bar occupancy, require removal, and impose fines. The county does not enforce this.
