Read this before you act on anything below. This is my researched starting point for Parker 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 rulesParker County, TX

Zoning & raw-land occupancy
Generally allowedParker County's own permitting page states there are no zoning requirements in unincorporated areas of the county. Cities like Weatherford zone within their limits and ETJ, and private deed restrictions can still apply. source
Dwellings, tiny homes & RVs
Unclear - verifyNo standalone county ordinance on tiny homes or RV occupancy was found; the county's Subdivision Rules govern platting and groundwater certification for new subdivisions. Confirm with the county Platting Office and check city ETJ rules if near a municipality. source
Building permits & codes
Generally allowedThe county issues building-related permits and plan review, including a Certificate of Compliance process under state Local Government Code provisions; commercial/multifamily projects also route through the Fire Marshal. Confirm the currently adopted code edition directly with the county. source
Septic & composting toilets
Generally allowedParker County is a TCEQ Authorized Agent administering OSSF permits under state law, including a statewide exemption for single-family homes on 10+ acre tracts meeting setback and nuisance conditions. Composting toilets aren't separately addressed and likely fall under the same process. source
Greywater reuse
Unclear - verifyNo standalone Parker County greywater ordinance was found; greywater appears to be handled within the general OSSF/state framework. Ask the Permitting Department how they treat greywater systems tied to septic permits.
Rainwater harvesting
Generally allowedTCEQ and the Texas Water Development Board provide guidance encouraging rainwater harvesting, and the local Upper Trinity Groundwater Conservation District runs a grant program and resource hub for it. No county permit threshold for tanks was found. source
Private wells & water rights
Varies locallyParker County falls under the Upper Trinity Groundwater Conservation District, which permits and registers new wells rather than leaving groundwater purely to rule-of-capture; new subdivisions on well water also need groundwater availability certification through the county. source
Living disconnected from utilities
Generally allowedNo county ordinance requiring utility connection in unincorporated areas was found, and the absence of zoning supports self-supplied power, well, and septic setups outside city limits. Cities and their ETJs may impose their own connection requirements. source
