Towns in Apache County: Eagar, Chinle, Fort Defiance.
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 Apache County has 238 FIRM panels, the newest effective September 2007; 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 an Apache 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 Arizona county parcel layers (each county publishes its own), so an Apache lot shows the same lines the county assessor draws. Apache County covers about 7,166,970 acres of land and 13,327 acres of water.
Mapped lines are approximate. The Apache County assessor keeps the parcel record (Apache County website); a licensed surveyor sets the true corners.
Zoning
Apache County zones its unincorporated land, and Eagar 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 Arizona's county zoning law (Arizona Revised Statutes Title 11, Chapter 6, Article 2, starting at 11-811), local governments can allow an accessory dwelling unit on a lot with a house. Whether an Apache 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. Apache County is soil survey area AZ635, Apache County, Arizona, Central Part, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Apache County needs a permit from the Apache County environmental services or health department, under authority delegated by the Arizona Department of Environmental Quality.
Setbacks
Setbacks in Apache 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 Eagar for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near an Apache lot and the Forest Service wildfire hazard rating at it.
