Read this before you act on anything below. This is my researched starting point for Garza County, TX, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesGarza County, TX

Zoning & raw-land occupancy
Generally allowedTexas law gives zoning authority only to cities, not counties, so Garza County has no countywide zoning ordinance for unincorporated land. Only the city of Post could have its own zoning within city limits. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Garza County document was found setting minimum dwelling size or rules for tiny homes and RVs. This is not confirmed either way; call the county clerk's office directly.
Building permits & codes
Varies locallyThe Garza County Clerk's office lists a Construction Permit Application Process, so some permitting exists, but whether it applies countywide or mainly to platted subdivisions isn't clear from the official page. source
Septic & composting toilets
Generally allowedSeptic systems (OSSFs) are regulated statewide by TCEQ; it's not confirmed whether Garza County is an Authorized Agent or whether permitting defaults to the TCEQ Region 1 Lubbock office. A statewide exemption may apply for tracts of 10 acres or more meeting specific conditions. source
Greywater reuse
Unclear - verifyNo standalone Garza County or TCEQ greywater rule was found; greywater is generally addressed within the state's OSSF/septic regulations rather than as its own permit track. source
Rainwater harvesting
Generally allowedNo Garza County ordinance restricting rainwater harvesting was found, and Texas state policy generally supports it for domestic use.
Private wells & water rights
RestrictedGarza County lies within the Garza County Underground Water Conservation District, which has adopted its own rules on drilling permits, well spacing, and waste under Chapter 36 of the Texas Water Code. source
Living disconnected from utilities
Unclear - verifyNo official Garza County ordinance requiring utility connection was found for unincorporated areas; any such rule would likely apply only inside Post's city limits, and no official Post municipal code was located to confirm.
