Doña Ana County, NM Parking Rules: RV & Boat Parking (2026)

Section 350-502B(6) of the Unified Development Code treats travel trailers and recreational vehicles as a use that belongs in a licensed RV park, not a residential yard or driveway, unless the property owner secures a temporary use permit. The first path applies when the owner is building or remodeling a site-built home: with a valid building permit in hand, the county can issue a temporary use permit letting the family live in the RV or mobile home on site. That permit runs six months and can be renewed once for another six months if construction is still progressing, but the exception disappears automatically 30 days after the new house receives its certificate of occupancy.

The second path covers stays longer than seven days for any other reason; either way, the code caps occupancy at one travel trailer or recreational vehicle per property, so a second unit parked in a side yard or on a driveway pad is not permitted even under a valid temporary permit. Owners in a FEMA-mapped special flood hazard area face an added layer: § 350-604G(5) applies specific floodplain placement and anchoring standards on top of the general parking limit. Because the rule sits inside the general-to-all-zones article, it reaches every residential, agricultural and mixed-use zoning district in the unincorporated county alike; Las Cruces, Sunland Park, Mesilla and Hatch each administer this question under their own municipal codes, not this section.
