Read this before you act on anything below. This is my researched starting point for Montague County, TX, not legal advice and not a guarantee. 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 rulesMontague County, TX

Zoning & raw-land occupancy
Generally allowedTexas commissioners courts generally lack authority to regulate land use, building bulk, or size on unincorporated land, and Montague County is mostly unincorporated. The county does enforce subdivision regulations for platting and a floodplain development ordinance. source
Dwellings, tiny homes & RVs
Unclear - verifyNo countywide minimum house size, tiny-home, or RV occupancy rule was confirmed; the county has adopted rules for manufactured home rental communities specifically. Incorporated towns may have their own stricter codes, so ask the town if you're inside city limits. source
Building permits & codes
Varies locallyNo general countywide building code was confirmed, but a Floodplain Development Permit is required for construction in a mapped Special Flood Hazard Area, administered by the county's Floodplain Administrator. source
Septic & composting toilets
RestrictedMontague County's Sewage Inspector is the authorized local agent under the state OSSF program, handling permits, inspections, and complaints for on-site sewage facilities per TCEQ rules. source
Greywater reuse
Unclear - verifyNo standalone county or TCEQ greywater ordinance was found; it is presumably handled through the OSSF/septic permitting process, but this is not confirmed. Ask the county Sewage Inspector directly.
Rainwater harvesting
Generally allowedThe Upper Trinity Groundwater Conservation District, which covers Montague County, actively promotes and has funded rainwater harvesting projects, and no county restriction was found.
Private wells & water rights
RestrictedThe Upper Trinity Groundwater Conservation District requires registration of wells drilled since 2009, with additional permitting, metering, and fees for non-exempt wells; registering an exempt well also protects spacing rights.
Living disconnected from utilities
Generally allowedNo countywide requirement to connect to electric, water, or sewer utilities was found; any such requirement would come only from a specific incorporated town's code, not the county.
