The local rulesBurnet County, TX
Zoning & raw-land occupancy
Unclear - verifyBurnet County has no countywide zoning; its authority over unincorporated land is mainly subdivision platting review under its Subdivision Regulations. Real zoning districts and setbacks apply only inside municipalities like the City of Burnet. source
Dwellings, tiny homes & RVs
Unclear - verifyNo countywide ordinance on dwelling size, tiny homes, or RV occupancy was found for unincorporated Burnet County; RV/trailer camp restrictions are confirmed only inside City of Burnet limits. Confirm with county Development Services for unincorporated land. source
Building permits & codes
Varies locallyBurnet County Development Services requires a building permit application for residential, manufactured home, and nonresidential construction, but no specific adopted county residential code was confirmed on an official page. source
Septic & composting toilets
RestrictedBurnet County has adopted the state's OSSF rules (30 TAC Chapters 285 and 30) by reference and permits septic systems through its Environmental Services Department as TCEQ's local agent; permits can be withheld for lots in noncompliant unrecorded subdivisions.
Greywater reuse
Unclear - verifyNo standalone Burnet County greywater ordinance was found; greywater appears to fall under the same adopted state OSSF framework as septic. Not confirmed as a distinct county rule.
Rainwater harvesting
Unclear - verifyNo Burnet County ordinance addressing rainwater harvesting permits or requirements was located on official sources; not confirmed at the county level.
Private wells & water rights
RestrictedThe Central Texas Groundwater Conservation District, coextensive with Burnet County, regulates well permitting for non-exempt wells, though about 85 percent of county wells are exempt from permitting as household wells. source
Living disconnected from utilities
Unclear - verifyNo Burnet County ordinance requiring connection to electric, water, or sewer service for unincorporated land was found; any hookup mandate would be city-specific inside municipal limits.
