Read this before you act on anything below. This is my researched starting point for Davis County, UT, 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 rulesDavis County, UT

Zoning & raw-land occupancy

Varies locallyUnincorporated Davis County zoning (Title 15.20) sets permitted and conditional uses by zone, like Agriculture Estate; incorporated cities have their own separate zoning that overrides county rules within city limits. Raw-land occupancy in tents or yurts isn't addressed, so treat it as unconfirmed. source

Dwellings, tiny homes & RVs

RestrictedDavis County's unincorporated code requires detached dwellings to be at least 600 square feet and allows only one dwelling structure per lot; tiny-home-on-wheels or RV-as-residence use is not clearly authorized, so check with County Planning or your city. source

Building permits & codes

RestrictedDavis County Community Development issues building permits under Utah's statewide construction code and can use third-party inspectors under state law when needed. source

Septic & composting toilets

RestrictedThe Davis County Health Department's Environmental Health Division permits onsite wastewater systems under state rule R317-4, and properties within 300 feet of public sewer may be required to connect instead. source

Greywater reuse

RestrictedNo Davis-specific greywater ordinance was found; it inherits the statewide rule (R317-401), administered by the same county Environmental Health office that handles septic permits. source

Rainwater harvesting

Generally allowedNo Davis County restriction on rainwater harvesting was found beyond the statewide law allowing it, so the state baseline applies as-is.

Private wells & water rights

RestrictedWell drilling permits come from the state Division of Water Rights; Davis County Health only recommends, not requires, water quality testing, but a well feeding a septic system must be approved before the county issues an OWS permit. source

Living disconnected from utilities

Unclear - verifyNo explicit Davis County rule was found on whether full grid disconnection is allowed; the clearest constraint is the county/state rule requiring sewer connection if a property sits within 300 feet of public sewer. source
