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

Zoning & raw-land occupancy

Varies locallyNo official Caddo County zoning ordinance or map was found; some sources direct residents to their city's planning department instead, suggesting zoning may be handled town-by-town. Whether unincorporated land is zoned at all is not confirmed. source

Dwellings, tiny homes & RVs

Unclear - verifyNo Caddo County rule on tiny homes, RVs, or minimum dwelling size was found; any such standard would likely come from a specific town, not the county. Not confirmed.

Building permits & codes

RestrictedUnincorporated Caddo County permits (including septic and renovation work) are filed through the County Clerk's Office; Anadarko has its own Building Inspector for in-town work. No distinct county building code page was found, so the state baseline likely applies. source

Septic & composting toilets

RestrictedOklahoma DEQ's Environmental Complaints and Local Services Division administers septic permitting statewide, including Caddo County, and requires a soil test before installing a subsurface system. The county health department refers septic questions directly to DEQ. source

Greywater reuse

Generally allowedNo Caddo County-specific greywater ordinance was found; the county appears to follow Oklahoma's general allowance for small-scale residential greywater reuse.

Rainwater harvesting

Generally allowedNo Caddo County ordinance restricting rooftop rainwater collection was found; the state baseline, which is permissive, appears to apply.

Private wells & water rights

Generally allowedThe Caddo County Health Department refers well and drinking water questions to Oklahoma DEQ; the state's domestic-use well exemption under OWRB rules is the applicable baseline, with no separate county rule found. source

Living disconnected from utilities

Unclear - verifyNo official Caddo County document addresses whether occupancy requires a grid electric or municipal water/sewer hookup. This is not confirmed and should be checked directly with the County Clerk.
