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 rulesNavarro County, TX
Zoning & raw-land occupancy
Varies locallyNavarro County has no countywide zoning ordinance except within 5,000 feet of the Richland-Chambers Reservoir shoreline, where a 1987 ordinance created nine zoning districts. Outside that lakeshore area, raw-land use is not restricted by county zoning. source
Dwellings, tiny homes & RVs
Varies locallyPlatted subdivisions require a minimum one-acre residential lot per county subdivision rules, and RVs used as dwellings within the lakeshore zoning district need a Specific Use Permit from the county. Countywide rules outside subdivisions and the lakeshore zone are not confirmed; ask Planning & Development. source
Building permits & codes
Generally allowedThe Navarro County Office of Planning and Development issues building permits, with the application depending on proximity to Richland-Chambers Lake, and floodplain development permits with engineer-sealed plans required near the lake. source
Septic & composting toilets
Generally allowedTexas requires an OSSF permit statewide under TCEQ rules to build, alter, or operate a septic system; Navarro County appears to administer its own OSSF permitting locally, but the specific local process is not fully confirmed, so check with the county. source
Greywater reuse
Unclear - verifyNo Navarro County greywater ordinance was found; the state addresses greywater within its OSSF rules rather than as a standalone program, and it's not confirmed whether the county has added anything separate. source
Rainwater harvesting
Generally allowedNo county-specific rainwater rule was found, so this inherits the generally permissive Texas state baseline for rainwater harvesting.
Private wells & water rights
Generally allowedNavarro County lies outside any Groundwater Conservation District, so the state rule of capture applies and TDLR handles well construction and driller licensing rather than a local permit; note incorporated towns like the City of Navarro have their own separate well permit rules within city limits.
Living disconnected from utilities
Unclear - verifyNo Navarro County ordinance was found requiring hookup to electric, water, or sewer utilities in unincorporated areas; any such mandate would come from an incorporated town's own rules, not the county.
