The local rulesSan Saba County, TX
Zoning & raw-land occupancy
Generally allowedTexas counties, including San Saba County, lack general zoning authority over unincorporated land, so raw land use outside town limits is largely unrestricted at the county level. The City of San Saba does zone within its own limits and ETJ. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county rule on minimum dwelling size, tiny homes, or RVs was found for unincorporated land; the City of San Saba regulates structures within its own limits via its Code of Ordinances. Confirm with the county directly. source
Building permits & codes
Unclear - verifyNo general residential building code was confirmed for unincorporated San Saba County; the county's permits page emphasizes right-of-way and underground crossing permits, while the City of San Saba has its own floodplain development permitting. source
Septic & composting toilets
Generally allowedSan Saba County administers its own On-Site Sewage Facility (OSSF) program as a TCEQ-authorized agent, following state rules under 30 TAC 285, with local design review through the county's adopted order. source
Greywater reuse
Unclear - verifyNo standalone county greywater ordinance was found; greywater is likely handled within the same OSSF/septic framework as the rest of Texas, but this is not separately confirmed. Ask the county's OSSF office. source
Rainwater harvesting
Generally allowedNo county restriction on rainwater harvesting was found, consistent with the general Texas state policy of encouraging rainwater collection.
Private wells & water rights
Unclear - verifyTexas's default rule of capture likely applies, but whether San Saba County falls within an active groundwater conservation district was not confirmed in official sources; check with the Texas Water Development Board or a neighboring district. source
Living disconnected from utilities
Generally allowedNo county ordinance requiring hookup to electric, water, or sewer utilities was found for unincorporated San Saba County; any such requirement would come from a town's own code inside its limits.
