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 rulesRoberts County, TX
Zoning & raw-land occupancy
RestrictedRoberts County has adopted a formal countywide Zoning Ordinance dividing unincorporated land into districts, including a Town District for Hammer and Victor, with a Zoning Administrator who enforces permit requirements. This is a county-level rule, unusual for rural Texas. source
Dwellings, tiny homes & RVs
Varies locallyThe Town District (Hammer and Victor) permits single-family homes including modular and manufactured housing. Treatment of tiny homes and RVs outside the Town District was not confirmed; ask the county Zoning Administrator. source
Building permits & codes
RestrictedThe county Zoning Ordinance requires a permit before starting work, with penalty fees for skipping it. Whether a specific building code like the IRC has also been adopted was not confirmed. source
Septic & composting toilets
Generally allowedSeptic (OSSF) systems are regulated statewide by TCEQ under Health & Safety Code Ch. 366 and 30 TAC 285, with an exemption available for qualifying 10+ acre single-dwelling properties. Whether Roberts County itself administers OSSF permits or defers to a TCEQ regional office was not confirmed. source
Greywater reuse
Unclear - verifyNo standalone county or state greywater-specific rule was found; greywater is generally handled within the broader OSSF framework. Not confirmed for Roberts County specifically, so ask TCEQ or the county. source
Rainwater harvesting
Generally allowedNo Roberts County restriction on rainwater harvesting was found, and Texas generally encourages the practice at the state level.
Private wells & water rights
RestrictedRoberts County falls under the Panhandle Groundwater Conservation District, which manages aquifer monitoring and planning countywide. Specific permitting, fees, or spacing rules were not confirmed in research and should be checked directly with PGCD. source
Living disconnected from utilities
Unclear - verifyNo Roberts County ordinance requiring utility hookup for occupancy in unincorporated areas was found, consistent with the usual Texas pattern of such mandates coming from towns rather than counties, but this was not directly confirmed for Roberts County.
