Code Compliance & Inspections
Work on your ADU Construction in Sandoval County will be inspected to ensure full compliance with the current New Mexico Building Code.
Concurrent Permits & HOAs
For Sandoval County residents, we recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Homeowners associations often maintain stricter rules regarding materials and dimensions for your ADU Construction than the county itself.
Zoning & Cost Factors
New Mexico zoning combines modern municipal codes in cities with historical preservation overlays, particularly regarding adobe architecture in places like Santa Fe. Fortunately, New Mexico maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What happens if I build a ADU Construction without a permit in Sandoval County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own ADU Construction permit in New Mexico?
Yes. New Mexico generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the New Mexico Building Code.
How much does a ADU Construction permit cost in Sandoval County?
Permit fees vary by jurisdiction and by your project's valuation, so Sandoval County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
How long does it take to get a ADU Construction permit in Sandoval County?
Processing time in Sandoval County varies by season and current application volume at the building department; contact Sandoval County Development for a current estimate.
