The New Mexico Environment Department handles septic permits5.

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

Unincorporated Valencia County requires a state building permit for construction work covered by statute or rule.

Unincorporated Valencia County requires a state building permit for construction work covered by statute or rule1. The state Construction Industries Division issues the permit, while Valencia County requires its own zoning and flood review before construction begins on any structure 120 square feet or larger2,6. State permit exceptions include a one-story detached tool or storage shed no larger than 120 square feet and a fence no higher than 6 feet, but separate trade permits may still apply12. Covered residential work follows the New Mexico Residential Building Code, which adopts and amends the 2021 International Residential Code8. Start with Valencia County Planning & Zoning, then complete the state permit application before beginning covered work12.

Who issues building permits in Valencia County, and what do they cost?

Start with the Valencia County Planning & Zoning Department at 444 Luna Avenue in Los Lunas; its page provides the county permit application and the state homeowner application.

Start with the Valencia County Planning & Zoning Department at 444 Luna Avenue in Los Lunas; its page provides the county permit application and the state homeowner application13. County applications require scaled plans showing parcel dimensions, existing and proposed structures, intended uses, dwelling units and surrounding land relationships14. The state Construction Industries Division handles inspections through its Albuquerque office3,6. Valencia County Code Enforcement handles county zoning review and issues floodplain certificates for buildings in designated floodplain areas15. State building-permit fees cover plan review, the permit notice and required inspections; CID calculates the fee from project valuation, accounting for construction type, square footage, materials and costs, and payment is required before issuance12,16.

Does Valencia County have zoning?

Yes.

Yes. Valencia County administers zoning on unincorporated land, while incorporated municipalities may have separate rules4. The published county zoning code includes agricultural-preservation, Outland, rural-residential, suburban-residential, commercial, industrial, planned-development and overlay districts17. Unincorporated land without an identified district is treated as Outland, but the comprehensive plan warns that its district map is for general planning only15. In RR-1 and RR-2, newly created parcels generally require 1 acre and 2 acres, respectively, subject to stated exceptions10. Both districts use a 30-foot front setback and 15-foot side and rear setbacks10. Dwelling height is capped at 30 feet; lot coverage is capped at 20% on parcels from 1 acre to under 10 acres and 15% on parcels under 1 acre10. Ask Planning & Zoning to identify the parcel's current district and overlays before applying those standards because district designations can change13,15.

How do septic permits work in Valencia County?

The New Mexico Environment Department's Onsite Wastewater Bureau administers septic permits in Valencia County.

The New Mexico Environment Department's Onsite Wastewater Bureau administers septic permits in Valencia County5. Submit the liquid-waste permit application to the local NMED field office before installing an onsite system7. A complete application may require ownership proof, a site diagram, a floorplan and a plat or survey; after approval and payment, the Permit to Construct is valid for 1 year unless the department grants a written extension18. A homeowner may install a simple conventional system only after passing the required written test18. Request the installation inspection at least 48 hours, or 2 business days, ahead and do not cover the system before inspection7. An approved final inspection produces a Permit to Operate7. Valencia County has 48.7% of soils rated without severe limits for a conventional drain field, but the specific site evaluation controls the design19.

Can you live in an RV, tiny home or manufactured home on your land in Valencia County?

In Valencia County's RR-1 and RR-2 districts, one RV may be parked with a principal dwelling and used for temporary guests for no more than 180 total days in a year.

In Valencia County's RR-1 and RR-2 districts, one RV may be parked with a principal dwelling and used for temporary guests for no more than 180 total days in a year10. An RV cannot serve as the principal dwelling or be rented unless the necessary permits, septic disposal and dwelling setbacks have been obtained10. The New Mexico building code recognizes a tiny house of up to 400 square feet, excluding lofts, when it provides complete living facilities, complies with the residential code and sits on a permanent foundation9. A tiny house on a chassis with a permanent axle is treated as an RV9. A manufactured or mobile home in unincorporated Valencia County generally must have at least 840 square feet of heated area, although a parcel-specific variance may be available11. A manufactured home also needs a state installation permit and final inspection; county standards require a permanent foundation inspected by CID or Manufactured Housing and approved by the County Building Inspector before occupancy, plus skirting after occupancy11,20. We could not confirm county zoning approval for tiny-home occupancy, a general minimum size for site-built homes or temporary camping; ask Valencia County Planning & Zoning about the proposed use13.

What are the steps to build and occupy a home in Valencia County?

Ask Valencia County Planning & Zoning to confirm the parcel's current district, overlays and whether the proposed home is allowed.

  1. Ask Valencia County Planning & Zoning to confirm the parcel's current district, overlays and whether the proposed home is allowed13,15.
  2. Prepare scaled plans and obtain county zoning and flood review before starting a structure 120 square feet or larger6,14.
  3. If the parcel needs onsite wastewater, apply to the New Mexico Environment Department for a liquid-waste permit7.
  4. Choose a licensed contractor or determine whether you qualify for a homeowner permit, which is limited to qualifying work on the owner's primary residence1.
  5. Submit the state building-permit application and pay the fee calculated from the project's valuation12,16.
  6. Build to the New Mexico Residential Building Code and request the required state inspections3,8.
  7. Complete required inspections and corrections; do not occupy the building until the appropriate inspector issues a certificate of occupancy or approved final inspection, as applicable3.

What should you check before buying land in Valencia County?

Confirm the current zoning district and overlays with Planning & Zoning rather than relying on a listing.

Confirm the current zoning district and overlays with Planning & Zoning rather than relying on a listing13,15. For an RR-1 or RR-2 homesite, verify legal, safe and passable access: the parcel must directly abut at least 30 feet of public road or use a qualifying private easement at least 30 feet wide10. Ask Code Enforcement whether the site falls in the Floodplain Overlay District because development there requires a floodplain permit before construction starts21. For a property with an existing septic system, the seller must obtain a qualified evaluation before transfer22. Valencia County averages 10.1 inches of precipitation annually and has experienced severe drought in 33.4% of years, so identify and verify the water source before closing19. We could not confirm the well-permit path or a countywide water-connection rule; ask the Office of the State Engineer about a proposed well and Planning & Zoning about connection requirements13.

Watch-outs

  • Valencia County has no building department of its own — the state Construction Industries Division issues the building permit, so budget time for both the county's zoning and flood review and a separate state permit application6.
  • A driveway onto a state highway needs its own access permit from the New Mexico Department of Transportation before you build it, separate from any county zoning approval23.
  • The RV, lot-size, setback, coverage, height and access standards apply specifically to RR-1 and RR-2; ask Planning & Zoning which district and overlays govern the parcel10,13.

New Mexico rules that apply here

  • Owner-builder exemptionConditional

    A New Mexico property owner constructing or altering the owner’s single-family primary residence, including permitted appurtenant structures, under a homeowner’s permit.

    • The exemption is limited to construction or alteration of the owner’s primary residence; other use cancels the current permit and can result in denial of later homeowner permits.
    • The homeowner must comply with CILA, NMAC rules, applicable standards and codes, and may act as the general contractor only when the major portion of the work, based on dollar amount, is completed by the homeowner.
    • A permit is required for all construction-related work for which a permit is required by statute or rule; the rule does not exempt the owner-builder from state permitting or inspections.
    • Homeowner permits are limited to single-family dwellings and appurtenant structures such as private garages, carports and sheds, require proof of ownership, and are subject to AHJ approval.
    • The application requires an AHJ-approved application, signed and notarized responsibility sheet, acknowledgement of the homeowner-permit instructions, local zoning approval, floodplain determination, proof of identity and ownership, and payment of required fees.
    • Separate homeowner permits may be issued for general building construction, mechanical/plumbing and electrical work; each is limited to the primary residence and does not apply to rental property, other owned property, or commercial work or property.
    • The homeowner is responsible for requesting inspections, correcting code violations, and requesting re-inspections for a certificate of occupancy or final inspection. Subcontractors remain responsible for permits, inspections and corrections for plumbing, mechanical and electrical work they perform.
    • The homeowner may perform authorized work personally or with W-2 employees, or subcontract part of the work while self-performing a significant portion. Subcontracted work must be performed by licensed contractors who obtain their own permits and pass required inspections.
    • A homeowner permit is invalid for a project managed, supervised or acted on as general contractor by a GB-2 or GB-98 contractor; that contractor must obtain the appropriate permits and assumes responsibility for the site work.

    • A homeowner-permit project may not be placed on the market for sale while under construction; doing so automatically voids the permit and may lead to unlicensed-contracting charges.
    • No more than one homeowner permit for a single-family dwelling may be issued to the same property owner within any 12-month period.
    • The cited rule section states an adoption/replacement date of March 10, 2022.

Water rights & wells in Valencia 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).
