Prescott is Arizona's one sourced construction application: of 3 sourced local nodes in the state, only Prescott carries an adopted book. The city took up the 2024 IWUIC on 2026-05-12, which makes what applies to your house a local code question rather than a model-code default.
An adopted book still arrives with open ends. The official map, the hazard class, the boundary, and the sign-off for your project all sit with the city, and what we can't tell you yet names each one instead of rounding them off.
For the yard, Prescott resolves to USDA half-zone 7b, where 383 of Arizona's 453 documented plant records apply — living here picks that thread up.
What applies to your house here
Prescott 2024 IWUIC application, adopted 2026-05-12, is the construction answer here.

Prescott 2024 IWUIC application
Prescott declares its entire incorporated city boundary a WUI, applies its amended 2024 IWUIC there, and uses City predictive modeling and GIS to assign extreme/IR1, high/IR2, or moderate/IR3 construction; boundary, project, risk-class, effective-date, and official checks remain open.
Arizona has 3 sourced local nodes;
1 has a sourced construction application.
Adoption is not statewide by implication: Flagstaff, Sedona have none sourced here.
These checks stay open because the sourced instrument leaves them to the official record, not because this page skipped them:
Whether the instrument is in force for this project's date.
The official boundary that would put a parcel inside the application.
Confirmation from the building official for this project.
The official hazard class for the lot.
The official hazard or WUI map for the lot.
Whether this project type is in scope of the instrument.
