Towns in Santa Fe County: Santa Fe, Eldorado at Santa Fe, La Cienega.
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 Santa Fe County has 85 FIRM panels, the newest effective December 2012; 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 Santa Fe 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 New Mexico county parcel layers (each county publishes its own), so a Santa Fe lot shows the same lines the county assessor draws. Santa Fe County covers about 1,222,643 acres of land and 653 acres of water.
Mapped lines are approximate. The Santa Fe County assessor keeps the parcel record (Santa Fe County website); a licensed surveyor sets the true corners.
Zoning
Santa Fe County zones its unincorporated land, and Santa Fe 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 New Mexico's zoning law for counties and municipalities (NMSA 1978, Chapter 3, Article 21, starting at 3-21-1), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Santa Fe 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. Santa Fe County is soil survey area NM687, Santa Fe County Area, New Mexico, last updated September 2026, on Web Soil Survey.
A new or changed septic system in Santa Fe County needs a permit from the New Mexico Environment Department Onsite Wastewater Bureau, through its field office for Santa Fe County.
Setbacks
Setbacks in Santa Fe 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 Santa Fe for land inside its limits.
Hazards that apply
