Albuquerque permits ADUs (locally called 'casitas') under the Integrated Development Ordinance (IDO, adopted 2018) Section 14-16-4-3(D)(4). Casitas are permitted by-right in all residential zones (R-A, R-1, R-MH, R-T, R-ML, R-MH). One ADU per single-family lot. Permits route through Planning Department via the Online Permit Portal. New Mexico has the Casita Rule (HB 252, 2023) that further preempts restrictive local rules.
Albuquerque IDO Section 14-16-4-3(D)(4) governs accessory dwelling units (casitas). One casita is permitted by-right on every residential lot in R-A, R-1, R-MH, R-T, R-ML, and R-MH zones. Dimensional standards: maximum 750 sq ft for detached casitas; maximum 600 sq ft for attached/interior casitas; maximum height 18 feet (matching surrounding accessory structure scale); setbacks per underlying zone (typically 5 feet side, 10 feet rear). Casitas may be detached, attached, or interior conversions. No minimum lot size requirement specifically for the casita. Required permits: building permit, electrical permit, plumbing permit, and mechanical permit through Albuquerque Planning Department Online Permit Portal. New Mexico HB 252 (2023) - the 'Casita Rule' - preempts municipal restrictions on ADUs of 750 sq ft or less on single-family lots, and Albuquerque's existing IDO largely complies. The Historic Preservation Division reviews casitas in Old Town, Huning Highland, Spruce Park, and other designated districts. Desert climate requires adobe-compatible construction in pueblo-style HOA neighborhoods.
Unpermitted casita construction violates IDO Section 14-16-6-1 with civil penalties up to $500 per day per violation. Building Safety may issue stop-work orders and demolition orders for unsafe structures. The City Attorney may seek injunctive relief. Liens may be placed on the property for unpaid fines and corrective work.
