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 rulesMohave County, AZ
Zoning & raw-land occupancy
Varies locallyMohave County has a countywide Zoning Ordinance with zones like A-R, R-E, and R-RV that set different rules for occupancy; a limited agricultural exemption exists for some large parcels but zoning is not absent countywide. Confirm your parcel's zone with the county's Planning & Zoning Division. source
Dwellings, tiny homes & RVs
Varies locallyRVs can get a one-year renewable temporary residential permit in A-R or R-E zones, but permanent RV dwelling generally requires an R-RV zone, RV park, or approved manufactured home park section. Appendix Q tiny-home adoption is not confirmed for the county. source
Building permits & codes
RestrictedBuilding permits are required countywide (effective since 2007), with an owner-builder option allowed by the state Registrar of Contractors; small unpowered sheds under a size threshold are exempt. Electric service to a property is tied to the first building permit, per the county's Building Division FAQ. source
Septic & composting toilets
Generally allowedMohave County Development Services handles septic permitting under authority delegated by ADEQ, covering conventional and some alternative systems; composting toilets appear to be reviewed case-by-case rather than automatically approved. source
Greywater reuse
Generally allowedNo Mohave County-specific greywater ordinance was found beyond Arizona's state ADEQ tiered general permit, which is the baseline that applies here.
Rainwater harvesting
Generally allowedNo county ordinance restricting residential rooftop rainwater harvesting was found; this appears to follow the statewide no-permit baseline.
Private wells & water rights
Generally allowedMohave County is outside Arizona's Active Management Areas, so exempt domestic wells (35 gpm or less, capped annual use) are generally available via an ADWR Notice of Intent to Drill; the county coordinates well-to-septic separation distances. source
Living disconnected from utilities
Varies locallyThere's no state or county mandate to connect to the grid, but per the county's Building Division, electric service to a property is granted through the first building permit and is not permitted on vacant land, tying off-grid solar setups to the permit process for habitable structures. source
