Zoning, building permits and septic rules in Ruidoso Downs, New Mexico

Building a home in Ruidoso Downs, New Mexico takes two permits: the city's Planning & Zoning Department signs off first, the state Construction Industries Division (CID) issues the construction permit, and the city then issues its own permit12. Zoning is the city's own, under Chapter 155 of the city code3. Septic permits come from the New Mexico Environment Department, not the city4.

Do you need a building permit in Ruidoso Downs, New Mexico?

Yes. Ruidoso Downs requires permits for new construction, additions, remodels and manufactured or modular houses inside city limits1. Construction may proceed only after permits are issued1.

The one exemption worth knowing: a detached residential or commercial accessory structure of 120 square feet or less, with the minimum required separation, does not need a construction permit, though it may still need a land development permit6. The small-structure exemption does not apply in flood zones6.

Who issues building permits in Ruidoso Downs, and how do you reach them?

The state issues the construction permit, and the city adds its own. All construction permits in Ruidoso Downs are issued through the New Mexico Construction Industries Division, and builders must first get sign-off from the city's Planning & Zoning Department8. After the state permit arrives, the city issues its city permit2.

Inspections are also a state job: Ruidoso Downs no longer has building inspectors, so inspection requests and permitting questions go to CID58. Reach CID's Albuquerque office at (505) 222-98009. Reach the city's Planning & Zoning Department at 575-378-13428. We could not confirm the city's permit fees; ask the Planning & Zoning Department.

Does Ruidoso Downs have zoning?

Yes. Ruidoso Downs has its own zoning under Chapter 155 of the city code, and the rules apply to all property inside city limits3. The city is divided into districts shown on an official zoning district map, including R-1 single-family, R-2 two-family and R-3 multiple-family residential districts10.

We could not confirm the lot sizes, setbacks, height limits, minimum dwelling size, or whether RVs, tiny homes or accessory dwellings may be lived in for any district. Those sit in the code's district regulations, so ask the Planning & Zoning Department which district a parcel is in before you buy8. Land divisions inside the city fall under the city's Chapter 156 subdivision rules11.

How do septic permits work in Ruidoso Downs?

Septic permits come from the New Mexico Environment Department, which sends applications to its local field office4. For Ruidoso Downs addresses, that is the NMED Ruidoso office at 575-258-327212. A permit is required before a system is installed or modified13. A conventional system up to 1,000 gallons per day carries a $225 fee, and NMED must inspect before the system is covered1314.

We could not confirm whether a given lot inside the city must connect to city sewer instead of using a septic system. Ask the city's Planning & Zoning Department about sewer availability before planning a septic field8.

Can you live in an RV or tiny home in Ruidoso Downs?

We could not confirm the city's rules on living in an RV, camping, tiny homes, manufactured homes or accessory dwellings on a lot inside Ruidoso Downs. The answer depends on the zoning district and on the city's code, so call the Planning & Zoning Department before parking or placing anything on a lot8.

One state-level fact applies: a tiny house on a permanent foundation must comply with the New Mexico Residential Code, and a tiny house on a chassis with a permanent axle is treated as a recreational vehicle15.

Building a home in Ruidoso Downs: the steps, in order

  1. Ask the city's Planning & Zoning Department which zoning district the parcel is in and whether it sits in a special flood hazard area87.
  2. Get planning and zoning sign-off from the city1.
  3. Apply for the state construction permit through the Construction Industries Division29.
  4. Receive the city permit once the state permit is issued2.
  5. Get the septic permit from NMED's Ruidoso office, or confirm sewer service with the city412.
  6. Call CID for inspections, since the city has no building inspectors5.

What stays with Lincoln County, and what to check before you buy

Inside Ruidoso Downs, the city handles zoning and its city permit, the state handles construction permits and inspections, and NMED handles septic. Land outside city limits follows Lincoln County rules, not the city's.

Driveways onto a state highway need an access permit from the New Mexico Department of Transportation16. Street cuts in city right-of-way need a city permit from Public Works at 575-378-616217. Wells require a permit to drill from the State Engineer18. Lincoln County's effective property tax rate is 0.5%19.

Watch-outs

  • Lot size, setback, height and RV rules for each Ruidoso Downs zoning district are unconfirmed, so get them in writing from the Planning & Zoning Department before you buy8.
  • Construction in a special flood hazard area must follow specific provisions, and the small-structure permit exemption does not apply in flood zones76.
  • A homeowner permit for building your own primary residence is available statewide through CID, but we could not confirm how the city applies it; ask CID and the Planning & Zoning Department20.
