Frequently Asked Questions
Can I build an ADU on my Albuquerque property?
Yes. Albuquerque's Integrated Development Ordinance (IDO) allows ADUs by right in R-1 zones — one of the more straightforward ADU approval processes in New Mexico. Detached ADUs are limited to 750 sqft. You need a building permit from Albuquerque Development Services. ABCWUA (water utility) connection fees apply for new utility service. No state-level ADU preemption exists in New Mexico, but Albuquerque's local IDO is supportive of ADU development.
What is the Integrated Development Ordinance (IDO)?
The IDO is Albuquerque's main zoning code, adopted in 2017. It replaced the previous Development Code and combined zoning, subdivision, and development standards into a single document. The IDO introduced by-right ADU allowances in R-1 zones, streamlined approval processes for many projects, and created mixed-use corridor zones along transit routes. The IDO is administered by the Albuquerque Planning Department.
Are short-term rentals (Airbnb) allowed in Albuquerque?
Yes, with an STR license ($150/year). Both owner-occupied and non-owner-occupied STRs are allowed. New Mexico Gross Receipts Tax (GRT) and Bernalillo County Lodgers Tax must be collected on all STR stays. Platforms like Airbnb collect and remit applicable taxes. Noise ordinance and occupancy limits apply. Your license number must appear on all booking platform listings.
How good is solar in Albuquerque?
Excellent. Albuquerque has approximately 310 sunny days per year and sits at 5,312 ft elevation — high altitude increases solar intensity. This makes Albuquerque one of the best solar markets in the US. PNM net metering credits solar generation at retail rate. New Mexico property tax exemption prevents assessment increases for solar installations. No permit is particularly complicated — contact Albuquerque Development Services for the electrical permit process.
Is my property near the Rio Grande bosque?
The Rio Grande bosque (cottonwood riparian forest) runs north-south through central Albuquerque. Properties within the bosque corridor have additional development restrictions — arroyo buffers, riparian setbacks, and floodplain regulations from both the city and the U.S. Army Corps of Engineers. Check the FEMA Flood Map (msc.fema.gov) and the City's GIS mapping at cabq.gov/planning/zoning to determine your property's flood zone and proximity to the bosque.
Does Albuquerque have historic district restrictions?
Yes. Albuquerque has 4 locally designated historic districts: Old Town, Barelas, Huning Highland, and Martineztown-Santa Barbara. If your property is in one of these districts or is a designated landmark, exterior alterations require a Certificate of Appropriateness from the Historic Preservation Commission before building permits are issued. Old Town is particularly significant — a Spanish colonial plaza area founded in 1706 with strict design standards.
