Does La Junta, Colorado have zoning, and what does it mean for RVs and tiny homes?

Yes. La Junta's municipal code refers to residential zones R-S, R-1A, R-1, R-2 and R-3, plus commercial, agricultural and industrial zones⁵. The City of La Junta Engineering Department manages planning, zoning and variances for the city¹. Zone changes, lot splits, variances and conditional use permits are separate applications, each with its own form on the Engineering page¹.

For RVs, the code allows parking a trailer or RV on private property in a residential zone only in set situations: in a trailer park, with the landowner's consent, in a rear yard, or in enclosed storage⁶. No one may maintain living quarters in an RV for more than 48 hours outside a properly zoned trailer camp or park⁶.

For tiny homes, Colorado's Division of Housing says its regulated tiny homes are approved for long-term living⁸. We could not confirm whether La Junta's zoning accepts a tiny home on a given lot, so ask the Engineering Department before you buy. We also could not confirm minimum lot sizes, setbacks or minimum dwelling size for any district.

Do you need a building permit in La Junta, and who issues it?

The City of La Junta Engineering Department handles building permits inside city limits, and it reviews plans and checks building code compliance¹. The city's page says a building permit is required before anyone constructs, enlarges, alters, repairs, removes, converts or replaces regulated electrical, gas, mechanical or plumbing systems¹. The city has adopted the 2018 International Residential Code, with amendments, for detached one- and two-family dwellings and townhouses³.

We could not confirm a fee schedule, inspection steps, a certificate of occupancy rule or an owner-builder exemption for the city, so ask the Engineering Department. Colorado's statewide owner exemption covers only repair or maintenance work on your own property, and only in counties with a contractor-licensing program, so it does not clearly cover a new house in the city⁹.

The county's building rules do not apply inside the city. Land outside city limits falls under Otero County.

Who do you contact about building permits and zoning in La Junta?

Contact the City of La Junta Engineering Department at 719-384-5991, in the Municipal Building at 601 Colorado, La Junta, CO 81050¹. The department says that is the number for questions about building permits or zoning requirements¹.

Do not go to the Otero County Land Use Office or Building Department in Rocky Ford for a lot inside city limits; those offices serve unincorporated Otero County¹⁰. The city's page also lists forms for the planning commission, including zone change, lot split, variance and conditional use applications¹.

How do septic permits work in La Junta?

Septic permits come from Otero County, not the city. The county's Health Department Environmental Health Services pages carry the onsite wastewater treatment system permit application⁴. Colorado requires a permit to construct, alter, install or repair an onsite system where a building is not served by a sewage treatment works, and a final inspection by the local public health agency¹¹¹².

Inside La Junta, many lots will not use septic at all. City code requires premises on a street with an established sewer, or within 400 feet of one, to be equipped with sanitary plumbing fixtures, and the City Council can require connection¹³. We could not confirm which lots may use septic instead, or the city's water connection rule. Ask the Engineering Department whether a sewer reaches your lot, then ask the Otero County septic inspector if it does not¹⁴.

Wells need a state permit, because every new groundwater-diverting well in Colorado needs one¹⁵.

Building a home in La Junta: the steps, in order

1. Call the City of La Junta Engineering Department to confirm your lot's zone district and whether your plan fits it¹.
2. Ask whether a sewer line serves the lot; if none does, plan for county septic review¹³⁴.
3. Apply for the building permit with the plan-submission checklist the city publishes, and build to the 2018 International Residential Code as amended¹³.
4. If you need a driveway opening through a city curb, get a written permit from the City Engineer first; new-construction plot plans must show proposed driveways⁷.
5. If the lot lies in a flood hazard area, check the city's flood damage prevention rules (Chapter 15.52) before you design¹⁶.
6. For electrical, plumbing or gas permits, the city points to the State of Colorado¹.

What stays with Otero County, and what should you check before buying in La Junta?

Septic permits and the septic inspector stay with Otero County⁴. For land outside city limits, the county's own building permit and zoning rules apply instead of the city's¹⁷¹⁰. See the Otero County page for that land.

Before buying inside the city, check four things. First, the zone district, because RV and trailer rules depend on it⁶. Second, flood hazard status: an RV in a flood area must be on site fewer than 180 consecutive days, be licensed and highway-ready, or meet manufactured-home permit, elevation and anchoring rules¹⁶. Third, sewer availability¹³. Fourth, access: a driveway through a city curb needs a written City Engineer permit⁷. At the county level, Otero County's effective property tax rate is 0.3%¹⁸.

Watch-outs

• Living quarters in an RV on private property inside La Junta are limited to 48 hours outside a properly zoned trailer camp or park⁶.

• Camping on public property inside La Junta is unlawful unless the governing authority specifically authorizes it¹⁹.
