Towns in Davis County: Layton, Bountiful, Clearfield.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Davis County has 75 FIRM panels, the newest effective September 2022; coastal V zones, where waves add to the flood, are mapped along its shore.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Davis house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Utah Geospatial Resource Center (UGRC), statewide parcels from county recorders and assessors, so a Davis lot shows the same lines the county assessor draws. Davis County covers about 207,936 acres of land and 198,727 acres of water.
Mapped lines are approximate. The Davis County assessor keeps the parcel record (Davis County website); a licensed surveyor sets the true corners.
Zoning
Davis County zones its unincorporated land, and Layton, Bountiful, Clearfield each zone the land inside their limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning and zoning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Utah's County Land Use, Development, and Management Act (Utah Code Title 17, Chapter 79), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Davis lot can add one depends on its district; the county planning and zoning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Setbacks
Setbacks in Davis County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the county zoning office gives them for the lot's district, and Layton, Bountiful, Clearfield for land inside their limits.
