The local rulesLampasas County, TX
Zoning & raw-land occupancy
Varies locallyLampasas County has no general zoning authority over unincorporated land, a common limit on Texas counties. Zoning applies only inside city limits/ETJ, administered by the City of Lampasas Building and Planning Department. source
Dwellings, tiny homes & RVs
Unclear - verifyNo standalone county ordinance on minimum dwelling size or RV occupancy was confirmed; manufactured home communities in subdivisions must follow nuisance, floodplain, and septic rules. Confirm specifics with Lampasas County directly. source
Building permits & codes
Unclear - verifyNo countywide building code was confirmed for unincorporated land. Inside the City of Lampasas, the Building and Planning Department enforces adopted building and trade codes. source
Septic & composting toilets
RestrictedLampasas County is the TCEQ-authorized OSSF permitting authority and has adopted rules stricter than the state minimum under 30 TAC 285.10, including specific minimum-acreage and flow provisions for RVs. source
Greywater reuse
Unclear - verifyNo standalone county greywater ordinance was found; it appears to be handled under the county's OSSF order following the state's 30 TAC Chapter 285 framework. Not independently confirmed.
Rainwater harvesting
Generally allowedNo county restriction on rainwater harvesting was found, so it appears to follow the state's generally permissive, TWDB-supported baseline.
Private wells & water rights
RestrictedMost of Lampasas County lies within the Saratoga Underground Water Conservation District, which requires well registration/permitting under Texas Water Code Chapter 36. A small portion of the county may instead fall under the Central Texas GCD, so confirm which district covers your land. source
Living disconnected from utilities
Generally allowedNo county rule requiring connection to electric, water, or sewer utilities was found for unincorporated land. Mandatory hookup rules, if any, would come from a city within its limits or ETJ.
