Read this before you act on anything below. This is my researched starting point for Comanche County, OK, 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 rulesComanche County, OK

Zoning & raw-land occupancy

Varies locallyNo countywide zoning ordinance was found; incorporated towns like the City of Comanche have their own Planning & Zoning Commission, but unincorporated county land's status is not confirmed. Call the relevant municipal planning office or Comanche County government directly. source

Dwellings, tiny homes & RVs

Unclear - verifyNo Comanche County or municipal rule on tiny homes, minimum square footage, or RV occupancy was found; this is not confirmed either way.

Building permits & codes

Varies locallyConfirmed at the municipal level (e.g., City of Comanche issues building permits and certificates of occupancy); no official Comanche County building department page was found for unincorporated land. source

Septic & composting toilets

RestrictedSeptic systems are permitted through the Oklahoma DEQ's On-Site Sewage Program, a state authority, with local support from Comanche County Health Department sanitarians. Composting toilets are not separately addressed, so the state's restricted approach applies. source

Greywater reuse

Generally allowedNo Comanche County ordinance modifies the state's general allowance for residential greywater reuse for irrigation; this is inherited from Oklahoma state rules.

Rainwater harvesting

Generally allowedNo county-specific rainwater ordinance was found; rooftop non-potable rainwater collection is governed by state law without added county permitting.

Private wells & water rights

Generally allowedDomestic wells fall under state rules (Oklahoma Water Resources Board domestic exemption), with water testing support from Oklahoma DEQ's State Environmental Lab; no county-specific well ordinance was found. source

Living disconnected from utilities

Unclear - verifyNo official Comanche County or municipal page was found addressing mandatory utility hookups tied to occupancy; this is not confirmed either way, so ask local building officials directly.
