City and state leaders promote Accessory Dwelling Units (ADUs), or casitas, as a promising solution to Albuquerque’s housing shortage. Yet very few are actually built because the cost to build one vastly outweighs the value it adds to the property.
Because an ADU cannot be separated from the primary home’s land, conventional lenders view it as a secondary amenity rather than an independent asset. Appraisers can assign value only to the structure itself - the land remains tied to the main residence. Homeowners cannot obtain standard financing to build them, restricting construction to those with deep pockets. Custom builds also mean paying top retail rates with no economies of scale.
Albuquerque’s neighborhoods with alleyways are ideal locations for ADUs. A casita with rear access can have its own entrance, parking, and utilities while preserving the front streetscape and the primary home’s privacy and use. This configuration supports gentle density without neighborhood disruption.
New Mexico should authorize “ADU-to-condo” conversions. By allowing homeowners to convert their property into a two-unit condominium regime, the land remains intact - avoiding conflicts with existing mortgage holders - while the casita gains its own legal title, ideally facing the alleyway. This enables independent financing and sale as an affordable starter home.
The city must also cut construction costs, by promoting prebuilds which are craned in and standardized caps on utility connection fees to protect homeowners from surprise tap fees running into tens of thousands of dollars.
Zoning changes only grant permission to build. Until we fix the underlying financing, valuation, and scale problems, casitas will stay a luxury option rather than a practical solution for working families.
