Do you need a building permit in Eddy County, New Mexico?

A residential building permit is required for work in Eddy County covered by the New Mexico Residential Code, and the New Mexico Construction Industries Division (CID) issues the permit for unincorporated areas because Eddy County has no local building department¹². Listed exceptions include certain one-story detached tool sheds, storage sheds, playhouses and similar accessory buildings no larger than 200 square feet, but separate plumbing, electrical or mechanical permits may still be required¹. Covered residential construction follows the 2021 New Mexico Residential Building Code, while energy, electrical, plumbing, mechanical and other codes may also apply to the work¹². A homeowner may apply to build, alter, repair or improve a residence, but must sign the application and a notarized Homeowner's Responsibilities Form; the homeowner route cannot be used when a GB-2 or GB-98 contractor is acting as general contractor⁶. Required inspections still apply¹³.

Who issues building permits in Eddy County, and how do you reach them?

There is no Eddy County building department: the New Mexico Construction Industries Division issues residential building permits for unincorporated Eddy County, and the Las Cruces District Office is at 505 South Main Street, Las Cruces, NM 88001, phone 575-524-6320¹⁴². A homeowner submission requires county planning and zoning approval, two complete sets of plans, the Multi-Purpose State Building Application and payment of the fee provided by CID³. CID says a complete homeowner package is issued within 5 working days and residential permits are generally processed in 3 to 4 working days³. Eddy County Planning & Development is at 101 W Greene Street, Suite 228, Carlsbad, NM 88220, phone 575-887-9511¹⁵. Construction permit fees vary with the work, square footage, materials and construction cost¹⁶. Applications may also be completed through CID's online permitting portal¹⁷.

Does Eddy County have zoning?

Eddy County regulates land use countywide through its Land Use ordinance (O-02-41) and Subdivision Regulations (O-13-76), administered by Planning & Development⁵. New Mexico law lets a county adopt zoning for any territory not already inside a municipality's own zoning jurisdiction, which is the authority behind Eddy County's ordinance¹⁸. The same office also administers Eddy County's own ordinances on manufactured-home placement, floodplain management, and work-force camps and recreational-vehicle parks, so a project touching any of those needs a look at county rules on top of the state building permit¹⁵. We could not confirm Eddy County's specific setback or minimum-lot-size rules for a typical rural parcel, so confirm those with Planning & Development at 575-887-9511 before you build¹⁵.

How do septic permits work in Eddy County?

Septic (on-site liquid waste) systems in Eddy County are permitted by the state New Mexico Environment Department rather than the county, and applications go to NMED's local Carlsbad field office at 406 N Guadalupe, Suite C, Carlsbad, NM 88220, phone 575-885-9023⁴¹⁹. New Mexico law bars installing or modifying an on-site liquid waste system, and bars building, modifying, or moving a dwelling onto a lot that needs one, until NMED issues the permit and the fee is paid²⁰. NMED generally acts within 10 working days of a complete conventional-system application, though review can extend further when more stringent requirements may be necessary²⁰. USDA soil survey data rates only 27.2% of Eddy County's soils as free of severe limits for a conventional septic drain field, so plan on a real site evaluation and possibly an engineered system on much of the county's land⁷. New Mexico also lets a homeowner install a simple conventional septic system after passing a qualification test, which is worth asking NMED about if you want to do the work yourself²¹.

Can you live in an RV or tiny home on your land in Eddy County?

Eddy County has its own Work Force Camps and Recreational Vehicle Parks Ordinance, but that ordinance governs RV parks and workforce camps as a land use, not whether you personally can park and live in a single RV on your own parcel, so don't read it as an answer to that question¹⁵. New Mexico's Residential Code separately allows a tiny house of up to 400 square feet, excluding lofts, to be used as a single dwelling unit if it meets the code's Appendix AQ and is inspected, but a tiny house still sitting on a chassis with its axle attached is treated as an RV instead and must meet RV codes and licensing⁸. A manufactured home needs its own state installation permit before it can be occupied, and Eddy County has its own Manufactured Home Placement ordinance on top of that state permit²²¹⁵. We could not confirm Eddy County's specific rule on long-term RV occupancy on a private rural parcel; ask Planning & Development at 575-887-9511 before you buy¹⁵.

Building a home in Eddy County: the steps, in order

Get county planning and zoning approval from Eddy County Planning & Development, 575-887-9511; that approval is part of a homeowner permit submission³¹⁵.
Prepare two complete sets of plans and the Multi-Purpose State Building Application, then submit them with the CID-provided fee³. If you will do the work yourself, sign the homeowner application and notarized responsibilities form⁶.
Apply through the CID online portal or contact the Las Cruces District Office at 575-524-6320¹⁷¹⁴.
Apply for the septic permit through NMED's Carlsbad field office at 575-885-9023 before placing a dwelling on a lot that needs an on-site liquid waste system¹⁹²⁰.
Get a New Mexico Department of Transportation access permit before building or changing access to a state highway²³.
Request the required building inspections as work progresses, with final trade inspections before the final general construction inspection¹³.

What to check before you buy land in Eddy County

Confirm the parcel's zoning under Eddy County's Land Use ordinance and whether it sits in a mapped floodplain, since Eddy County requires its own floodplain permit before construction or fill in a Special Flood Hazard Area⁵²⁴. Ask NMED's Carlsbad field office whether the parcel can pass a septic site evaluation; countywide, only 27.2% of soils rate free of severe limits for a conventional drain field, and Eddy County sees severe drought in roughly 41.4% of years, so water and soil questions deserve real scrutiny before you buy⁷²⁵¹⁹. If you are buying more than 35 acres that has been used for agriculture for the preceding 3 years, that sale may be exempt from New Mexico's Subdivision Act review⁹. Eddy County's typical home value is about $253,886 and its effective property tax rate is about 0.5%, for a median tax bill near $995 a year, well below many rural counties²⁶¹⁰¹¹. The nearest city of 100,000 or more people is about 117 miles from the county's center, and federal land covers 58.6% of the county²⁷²⁸.

Watch-outs

Eddy County's Work Force Camps and Recreational Vehicle Parks Ordinance regulates RV parks as a land use; it does not by itself establish whether you can live in a single RV on your own private parcel, so confirm that separately with Planning & Development¹⁵.
A New Mexico homeowner construction permit still requires county planning and zoning approval, plans, the state application, the CID-provided fee, and a notarized responsibilities form³⁶.
We could not confirm that the New Mexico Construction Industries Division's Las Cruces office is formally assigned to Eddy County; call 575-524-6320 before you drive there¹⁴.

county building authorityLimited
New Mexico counties that qualify as an authority having jurisdiction may administer permitting, inspection, and enforcement for residential construction in unincorporated areas and enforce applicable New Mexico construction codes.
- A county must have a full-service building department employing a full-time certified building official and have permitting, inspection, and enforcement authority over general construction, electrical, and mechanical-plumbing trades.
- A county established as an authority having jurisdiction before July 1, 2009 may continue with authority over specified trades without a full-service building department until it relinquishes that authority.
- Construction work subject to the Construction Industries Licensing Act and applicable rules requires the applicable permit before construction or specified installation, alteration, repair, maintenance, or demolition work begins, unless an applicable statute or rule provides otherwise.
- The statewide rule is effective March 10, 2022, unless a later date is cited at the end of a section.

Water rights & wells in Eddy County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Mexico’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellPermit required (issued by right)

Nearly all developed New Mexico lies inside an OSE 'declared' underground water basin, but a household 72-12-1.1 domestic well is a by-right permit the State Engineer issues even in closed/over-appropriated basins (metering can be required). The by-right amount is cut to 0.25 acre-ft/yr in a declared Domestic Well Management Area, and a few basin-specific orders cap it further (Gallup Order 197, Zuni Order 199) or stop issuing new domestic permits entirely (Hot Springs Order 198).

Limit: 1 acre-ft/yr by right (NMSA 72-12-1.1); 0.25 acre-ft/yr in a declared Domestic Well Management Area

Roswell Artesian Basinpartial of county
Pecos-connected artesian/shallow aquifer 'closed for an indefinite period' to new appropriations (State Engineer Order 7, 1937) and adjudicated under the Lewis decree; a new home cannot get a non-domestic right, but a 72-12-1.1 household domestic well is still issued (often meter-waived).
NM OSE Roswell Basin Guidelines (2005) ↗
Carlsbad Underground Water Basinpartial of county
OSE-declared Article-7 groundwater basin; new non-domestic (72-12-3) appropriations require an OSE permit showing unappropriated water. The 72-12-1.1 household domestic well remains by-right — no Domestic Well Management Area is declared in New Mexico. Lower-Pecos alluvial/Capitan aquifers hydraulically connected to the Pecos River, administered under the Pecos River Compact; effectively fully appropriated — new non-domestic supply by transfer/offset.
NM OSE Article 7 (Declared Underground Water Basins) ↗
Capitan Underground Water Basinpartial of county
OSE-declared Article-7 groundwater basin; new non-domestic (72-12-3) appropriations require an OSE permit showing unappropriated water. The 72-12-1.1 household domestic well remains by-right — no Domestic Well Management Area is declared in New Mexico. Capitan Reef aquifer in SE NM, largely brackish (oilfield/industrial supply).

Prior-appropriation state (first in time, first in right). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the New Mexico state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
