Texas Tiny House Zoning Laws Overview

Texas handles tiny housing differently from ADU‑forward states. There is no statewide ADU mandate, and most counties lack general zoning authority under Local Government Code Chapter 231. As a result, land‑use decisions are primarily made by cities (and sometimes within their ETJs), while counties regulate specific development items in unincorporated areas—floodplain, drainage, subdivision, on‑site sewage (OSSF), and access permits. For permanent tiny homes on foundations, the TDLR Industrialized Housing & Buildings program establishes statewide codes for modular units, and local jurisdictions adopt and enforce building codes. For tiny houses on wheels (THOWs), the Transportation Code treats them as trailers/vehicles; unless a local ordinance explicitly allows movable tiny homes as dwellings, they’re typically limited to licensed parks or temporary use. The practical path: confirm jurisdiction (city vs. county), check any ADU allowance, and work with the county’s development office on utility and safety requirements before you buy, build, or tow.

permanent residential status requires a specific local allowance. Begin with jurisdiction lookup

(city vs. county/ETJ), then coordinate with Development Services on utilities, fire access, and

drainage.

through city zoning. When built on a foundation to residential code, small homes can fit within

local ADU provisions where those exist. THOWs generally fall under vehicle/RV rules; permanent

residential status requires a specific local allowance. Begin with jurisdiction lookup (city vs.

county/ETJ), then coordinate with Development Services on utilities, fire access, and drainage.

through city zoning. When built on a foundation to residential code, small homes can fit within

local ADU provisions where those exist. Movable tiny houses (THOWs) are usually handled as travel

trailers; without a local ordinance, they aren’t dwellings. First confirm jurisdiction and zoning,

then verify floodplain, OSSF/septic, driveway, and utility requirements with the county.

Hutchinson County, Texas – Allow Tiny Homes?

Gray

than through city zoning. Foundation tiny homes follow locally adopted building codes; ADUs, where

allowed by the city, are the cleanest path to legality. Movable tiny houses (THOWs) are usually

handled as travel trailers; without a local ordinance, they aren’t dwellings. Start by confirming

whether the parcel is inside a city/ETJ, then check setbacks, utilities, floodplain, and access

standards.

Jack County, Texas – Allow Tiny Homes?

Gray

permanent residential status requires a specific local allowance. Begin with jurisdiction lookup

(city vs. county/ETJ), then coordinate with Development Services on utilities, fire access, and

drainage.

Matagorda County, Texas – Allow Tiny Homes?

Gray

In unincorporated parts of Matagorda County, development is reviewed at the county level rather than

through city zoning. Permanent tiny homes should be designed to residential code; if a city allows

ADUs, that’s often the most predictable route. Movable tiny houses (THOWs) are usually handled as

travel trailers; without a local ordinance, they aren’t dwellings. Begin with jurisdiction lookup

(city vs. county/ETJ), then coordinate with Development Services on utilities, fire access, and

drainage.

Webb County, Texas – Allow Tiny Homes?

Gray (ADUs via city; county regulates development in unincorporated areas)

In unincorporated parts of Webb County, development is reviewed at the county level rather than

through city zoning. Permanent tiny homes should be designed to residential code; if a city allows

ADUs, that’s often the most predictable route. THOWs generally fall under vehicle/RV rules;

permanent residential status requires a specific local allowance. Begin with jurisdiction lookup

(city vs. county/ETJ), then coordinate with Development Services on utilities, fire access, and

drainage.

Wharton County, Texas – Allow Tiny Homes?

Gray

Because Texas counties have limited zoning authority, Wharton County focuses on development permits

in unincorporated areas. Foundation tiny homes follow locally adopted building codes; ADUs, where

allowed by the city, are the cleanest path to legality. A tiny house on wheels (THOW) is typically

treated as a trailer/vehicle under the Transportation Code unless a local ordinance says otherwise.

Start by confirming whether the parcel is inside a city/ETJ, then check setbacks, utilities,

floodplain, and access standards.

Wheeler County, Texas – Allow Tiny Homes?

Gray

In unincorporated parts of Wheeler County, development is reviewed at the county level rather than

local ADU provisions where those exist. Movable tiny houses (THOWs) are usually handled as travel

trailers; without a local ordinance, they aren’t dwellings. First confirm jurisdiction and zoning,

then verify floodplain, OSSF/septic, driveway, and utility requirements with the county.
