ADU Design in Mosquero, NM

ADU Design in New Mexico: what governs your project

New Mexico has no statewide ADU statute; casitas and accessory dwellings are regulated by each city and county. Albuquerque, Santa Fe, and Las Cruces each maintain their own ADU standards within their zoning codes.

Energy code

Permitting varies by jurisdiction: typical local rules address size caps relative to the primary home, setbacks, and utility connections. Rural and county areas often have simpler review paths than the larger cities.

Permitting & plan check

The state's Construction Industries Division (CID) is the building authority across much of New Mexico, with Albuquerque, Las Cruces, and a few other cities running their own permitting. Because CID covers so much territory, state-level submittal standards apply on most projects.
