The local rulesCoconino County, AZ
Zoning & raw-land occupancy
Varies locallyCoconino County Community Development administers a countywide Zoning Ordinance for unincorporated land with density and use rules that vary by zone; electrical service is not permitted on vacant land without a permitted structure. source
Dwellings, tiny homes & RVs
Generally allowedTiny houses (600 sq ft or less), site-built ADUs, and manufactured homes are permitted under county rules with foundation and plan review requirements; using an RV as a residence requires a case-by-case county application. source
Building permits & codes
Generally allowedCoconino County is its own Authority Having Jurisdiction with its own adopted building code cycle; owner-builders are allowed to build their own home if plans are submitted and approved. source
Septic & composting toilets

Greywater reuse
Generally allowedGreywater reuse is allowed under both ADEQ's state rules and Coconino County's own Gray Water Guidelines, reviewed by the county's Environmental Quality division. source
Rainwater harvesting
Generally allowedCoconino County has adopted code allowing rainwater catchment to serve as a potable water source, beyond the state's non-potable baseline, though certain roofing materials require potability lab testing before use. source
Private wells & water rights
RestrictedPrivate wells are regulated at the state level by the Arizona Department of Water Resources, which requires a Notice of Intent to Drill; the county does not appear to add its own separate well-permitting layer, though this is not fully confirmed. source
Living disconnected from utilities
RestrictedLiving off-grid on a permitted, code-compliant home with solar and well/septic is acceptable and even promoted by the county's Sustainable Building Program, but the county explicitly prohibits electrical service to vacant, unpermitted land. source
