Tiny home rules in Plano, 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.
Plano has no dedicated tiny home ordinance. Site-built tiny houses must meet IRC and zoning minimum dwelling size rules. Tiny homes on wheels are treated as RVs and cannot be used as permanent residences.
Plano regulates tiny homes through its existing Zoning Ordinance and adopted International Residential Code rather than a specific tiny home provision. Site-built tiny houses on a permanent foundation must meet all IRC residential standards including the 2021 IRC Appendix AQ for tiny houses when locally adopted, which allows homes of 400 square feet or less with reduced ceiling height and loft standards. However, zoning district minimum dwelling sizes and Planned Development requirements typically exceed 400 square feet in Plano single-family districts, effectively limiting site-built tiny homes to ADU Backyard Cottage status (400 to 1,100 sq ft). Tiny homes on wheels (park model RVs and THOWs) are treated under Texas law as recreational vehicles and cannot be used as a permanent residence in Plano residential zoning districts. Manufactured homes are limited to designated manufactured home districts. Contact Plano Planning at 972-941-7151 to discuss specific proposals.
Zoning and building violations: citation, fines up to $500 per day, removal order for noncompliant dwellings, and cessation of illegal occupancy. RVs used as permanent residences are subject to separate enforcement.
