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 rulesComanche County, TX
Zoning & raw-land occupancy
Varies locallyComanche County has no countywide zoning ordinance since Texas counties lack zoning authority, but county subdivision regulations apply to platted land, and the City of Comanche has its own separate zoning ordinance for land inside city limits. source
Dwellings, tiny homes & RVs
Unclear - verifyNo standalone county ordinance on tiny homes or RVs was found; subdivision rules limit habitable structures to one per septic system on platted lots, but rules for unplatted acreage are not confirmed. Inside Comanche city limits, dwellings are subject to city zoning and permitting. source
Building permits & codes
Varies locallyNo evidence of a countywide building permit requirement for unincorporated Comanche County, but the City of Comanche requires a building permit application, fee, site plan, and multi-step review for anything inside city limits. source
Septic & composting toilets
Generally allowedSeptic (OSSF) systems are permitted and regulated under the standard Texas TCEQ framework, with Comanche County's subdivision regulations requiring systems that meet state and county standards and are inspected by a licensed sanitarian, engineer, or TCEQ agent. source
Greywater reuse
Unclear - verifyNo Comanche County-specific greywater ordinance was found; it likely falls under the same state OSSF framework referenced for septic, but this is not confirmed and should be checked with the county or TCEQ. source
Rainwater harvesting
Generally allowedNo county ordinance restricting rainwater harvesting was found, so it appears to follow the general Texas state baseline, which is permissive, though this is not separately confirmed at the county level.
Private wells & water rights
Varies locallyComanche County lies within the Middle Trinity Groundwater Conservation District, which regulates well drilling and production locally rather than leaving it to the state's default rule of capture; well owners should contact the District directly. source
Living disconnected from utilities
Generally allowedNo ordinance requiring connection to electric or water utilities in unincorporated Comanche County was found; the only clear mandatory connection is to an approved septic or sewer system within platted subdivisions. source
