Local Project Overview
Fence Installation · Union County, New Mexico
Set by local rules
In New Mexico, there is no single statewide rule for a Fence Installation; whether you need a permit is decided locally in Union County.
Fences are governed mainly by local zoning, not a statewide building permit. Cities set height limits (commonly 3-4 ft in front yards and 6 ft in back and side yards), setbacks, and corner sight-line rules, and many require a zoning permit for any fence. Most jurisdictions exempt fences up to 7 ft from a building permit (IRC R105.2) and require one above that. Replacing a fence at the same height, material, and location usually needs no permit; a fence used as a pool barrier always does. Because New Mexico leaves this to local jurisdictions, the reliable answer comes from Union County Clerk's Office. Zoning setbacks apply either way.

Installing a new fence can improve privacy and property value. However, most counties require a permit if the fence exceeds 6 feet in height or is located in the front yard.
With a population of around 4,013 residents, Union County generally runs a more streamlined permitting process than major urban hubs.
Code Compliance & Inspections
Work on your Fence Installation in Union County will be inspected to ensure full compliance with the current New Mexico Building Code.
Local Zoning & Setbacks in Union County
Regardless of the state permit rule above, Union County still enforces property-line setbacks and local zoning for your Fence Installation. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Union County Clerk's Office before building.
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 Fence Installation without a permit in Union 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 Fence Installation 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 Fence Installation permit cost in Union County?
Permit fees vary by jurisdiction and by your project's valuation, so Union 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 Fence Installation permit in Union County?
Processing time in Union County varies by season and current application volume at the building department; contact Union County Clerk's Office for a current estimate.
