Kane County, UT zoning map, flood zone and property lines by address
Free, no account. Or open the Utah map and tap a lot.
Towns in Kane County: Kanab.
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 has 11 FIRM panels covering Kane County, the newest effective September 2010; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Kane 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 Kane lot shows the same lines the county assessor draws. Kane County covers about 2,556,250 acres of land and 72,363 acres of water.
Mapped lines are approximate. The Kane County assessor keeps the parcel record (Kane County website); a licensed surveyor sets the true corners.
Zoning
Kane County zones its unincorporated land, and Kanab zones the land inside its 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 Kane 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.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Kane County is soil survey area UT642, Kane County Area, Utah, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Kane County needs a permit from the local health department that serves Kane County (under Utah DEQ onsite wastewater rules, R317-4).
Setbacks
Setbacks in Kane 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 Kanab for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a Kane lot and the Forest Service wildfire hazard rating at it.
