Arizona land feasibility & buildability

In Arizona the decisive questions are legal access and water. Cheap desert parcels are routinely landlocked, unserved by utilities, or sited in an unmapped wash.

Statewide rules that decide buildability in Arizona

  • Recorded legal access is the most common failure point on inexpensive rural parcels.
  • Well permits and assured water supply rules govern whether a home can be served.
  • County flood control districts regulate wash crossings and sheet flow.
  • Septic permits are issued at the county level under ADEQ rules.

What LotAnalyst checks automatically

  • Parcel area versus the zoning district minimum lot size, including legal non-conforming lots of record.
  • Front, side, and rear setback envelope and the resulting buildable footprint.
  • USGS 3DEP slope profile and grading implications.
  • Sewer availability versus septic feasibility and perc evidence.
  • FEMA flood zone, wetlands indicators, and stream or riparian buffers.
  • Road frontage and legal access, including landlocked parcels.
