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 rulesCoke County, TX
Zoning & raw-land occupancy
Unclear - verifyTexas counties generally lack zoning authority over unincorporated land under Local Government Code Chapter 211; no Coke County zoning ordinance or department was found, so this likely defaults to no zoning, but that's not confirmed specifically for Coke County.
Dwellings, tiny homes & RVs
Unclear - verifyNo Coke County ordinance on tiny homes, minimum dwelling size, or RV occupancy was found. Counties gained limited authority to set residential construction standards in unincorporated areas in 2009, but no evidence Coke County has adopted such rules.
Building permits & codes
Unclear - verifyTexas has no statewide building code, and no evidence was found that Coke County has adopted its own for unincorporated areas. Confirm with the Commissioners Court. source
Septic & composting toilets
Generally allowedSeptic systems (OSSFs) are permitted statewide under Texas Health & Safety Code Chapter 366 and TCEQ rules in 30 TAC Chapter 285, requiring an approved plan and permit. Whether Coke County itself is the authorized permitting agent or the TCEQ regional office handles it directly was not confirmed. source
Greywater reuse
Unclear - verifyNo separate greywater permit category was found for Coke County; greywater appears to be handled within the same state OSSF framework rather than as its own rule.
Rainwater harvesting
Generally allowedNo Coke County restriction on rainwater collection was found, and the state (via the Texas Water Development Board) generally encourages the practice.
Private wells & water rights
RestrictedThe Coke County Underground Water Conservation District requires well registration (Notice of Intent to Drill) and compliance with its own rules for non-exempt wells, in addition to state driller licensing requirements. source
Living disconnected from utilities
Unclear - verifyNo state or Coke County law was found mandating utility hookups in unincorporated areas; any such rule would come from a municipality like Robert Lee or Bronte, not the county.
