Tiny home rules in Round Rock, TX — 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.
A tiny home on wheels is titled as a travel trailer under Texas Transportation Code Section 501.002 and is not used as a permanent dwelling. A tiny home on a foundation with plumbing needs an OSSF septic permit.
Texas counties cannot zone, so unincorporated Williamson County sets no minimum house size. Classification depends on construction. A tiny home built on a trailer chassis meets the Transportation Code definition of a travel trailer, designed for temporary living quarters and not used as a permanent dwelling, and it is registered and titled as an RV rather than a house. A tiny home placed on a permanent foundation with a kitchen or bathroom needs an on-site sewage (OSSF) permit under Health & Safety Code Section 366.051. HOA deed restrictions commonly set minimum square footage that excludes tiny homes.
Living permanently in a titled travel trailer conflicts with its temporary-use classification. Placing a foundation tiny home on septic without an OSSF permit violates Chapter 366; HOA size minimums are enforced by the association.
