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 rulesHall County, TX
Zoning & raw-land occupancy
Generally allowedTexas law gives zoning authority only to cities, not counties, so Hall County has no zoning ordinance for unincorporated land. It's not confirmed whether the county has adopted narrower rules like floodplain or subdivision regulations.
Dwellings, tiny homes & RVs
Unclear - verifyNo Hall County ordinance on tiny homes, RVs, or minimum dwelling size was found; Texas has no statewide minimum size and counties have only limited construction-standard authority. Confirm with the county directly.
Building permits & codes
Unclear - verifyNo official record shows whether Hall County has adopted a building code for unincorporated areas; Texas has no statewide building code. The City of Memphis would have separate rules if the property is within city limits. source
Septic & composting toilets
Generally allowedSeptic systems (OSSFs) are regulated statewide by TCEQ under Health and Safety Code Chapter 366 and 30 TAC 285, typically enforced through a county-level authorized agent; it's not confirmed whether Hall County has its own agent or defers to the TCEQ regional office. source
Greywater reuse
Unclear - verifyNo separate Hall County or TCEQ greywater rule was found; greywater appears to fall under the general OSSF septic framework rather than its own program.
Rainwater harvesting
Generally allowedNo Hall County restriction on rainwater harvesting was found, and Texas state policy generally supports it.
Private wells & water rights
RestrictedWells in Hall County fall under the Mesquite Groundwater Conservation District, which handles siting, water quality, and rules for the area; small domestic/livestock wells on larger tracts may be exempt, but check with the district before drilling. source
Living disconnected from utilities
Unclear - verifyNo Hall County requirement to connect to electric, water, or sewer utilities was found; any mandatory hookup rule is more likely to come from the City of Memphis if inside city limits.
