Unincorporated Mesa County, Colorado requires a building permit for construction, issued by the county's Community Development building division1. Every parcel in the unincorporated county is zoned under the 2020 Mesa County Land Development Code2. Mesa County Community Development also administers septic systems -- formally on-site wastewater treatment systems, or OWTS -- and only 5.7% of the county's soil is rated without severe limits for a conventional drain field34.

Do you need a building permit in Mesa County, Colorado?

Yes. The Mesa County Building Department issues building permits and requires plan review for residential construction in the unincorporated county1. Colorado is a local-control state: county building-code adoption, permit requirements and inspection procedures are set locally rather than by a single statewide code10. Colorado law lets a board of county commissioners adopt a building code for unincorporated areas outside any city or town, require permits for construction, reconstruction, alteration or remodeling in the designated area, and it generally exempts buildings used solely to shelter agricultural implements, farm products, livestock or poultry11. We could not confirm a Mesa County owner-builder exemption from contractor licensing, so ask the Building Division before assuming one applies1213.

Who is the Mesa County building department, and how do you reach them?

Community Development is Mesa County's building, planning and septic department, housed together in the county's Central Services building13. The county's permit page provides plan-submittal requirements, permit-clearance requirements and application forms; permit issuance is limited after 4:30 p.m., and the office will not issue multiple permits after that time14. Reach Community Development at 970-255-7169, at 200 South Spruce Street, Grand Junction, CO 81501, Monday through Friday, 8:00 a.m. to 5:00 p.m.13. For roads, driveway access onto a county road, or floodplain questions, contact the Public Works Division at 970-244-1765, also at 200 S. Spruce Street, Grand Junction, CO 8150115.

Does Mesa County have zoning?

Yes. All parcels in unincorporated Mesa County are zoned and regulated under the 2020 Mesa County Land Development Code, administered by the Planning Division of Community Development2. The county publishes zoning districts under that code, and development must be consistent and compatible with the uses allowed in the parcel's applicable district16. Colorado law allows county zoning to regulate building location, height, lot coverage, lot size, density and land use in unincorporated territory17. District-specific dimensions and uses vary, so ask Planning to confirm the parcel's district, setbacks and proposed use before you buy18. Colorado's accessory-dwelling-unit mandate applies only in defined subject jurisdictions, so ask Planning whether it reaches a parcel near Grand Junction rather than assuming it applies to rural land1918.

How do septic permits work in Mesa County?

Mesa County's Public Health Board designated Community Development to administer on-site wastewater treatment systems, or OWTS, under county regulations that incorporate Colorado requirements3. Sewer availability from a municipality or special district can affect whether the county will issue an OWTS permit3. During installation, the tank and soil-treatment area must be inspected before they are covered, concealed or backfilled; deficiencies require correction and another inspection, and final OWTS approval comes before a certificate of occupancy where applicable20. Soils are a serious constraint: only 5.7% of Mesa County soil is rated without severe limits for a conventional drain field, so start the site evaluation early and be prepared for an engineered or alternative design4.

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

Colorado allows tiny homes for long-term living, but only after the Colorado Division of Housing approves the unit's plans for the specific site, and the unit must still meet local zoning7. A tiny home approved for one site in Colorado is not automatically approved elsewhere -- moving it to another site can require new design review7. Manufactured (HUD-code) homes can be installed anywhere in Mesa County that local zoning allows, once installation is certified and inspected under Colorado Division of Housing rules; local jurisdictions may require site work for wind and snow loads, but that cannot change the construction of the home itself8. We could not confirm Mesa County's rule for long-term RV living on a private rural parcel outside a campground, so ask Planning before moving a camper onto the land18.

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

  1. Confirm your parcel's zoning district, allowed use and dimensional limits with Community Development's Planning Division before you buy or design1618.
  2. Ask Community Development whether sewer availability affects the parcel, then apply there for an OWTS permit if septic is appropriate; soils here often need extra evaluation, so start early34.
  3. Apply for a well permit through the state Division of Water Resources before drilling; complete applications can take up to 49 days to review6.
  4. Use the county's plan-submittal, permit-clearance and application materials to prepare the building-permit filing14.
  5. If your driveway will connect directly to a state highway, apply for a CDOT access permit; a single-family or agricultural Level 1 permit costs $509.
  6. Have the OWTS tank and soil-treatment area inspected before covering them, correct any deficiencies, and obtain final approval before occupancy where applicable20.
  7. For anything involving a floodplain, or access onto a county road instead of a state highway, check with the Public Works Division15.

What to check before you buy land in Mesa County

Mesa County is remote: about 186 miles from the nearest large city, with a population density of about 48 people per square mile, though the county's own city, Grand Junction, provides services much closer than that2122. Roughly 73.2% of the county is federal land -- BLM and national forest, mostly in its mountainous and high-desert terrain -- so check whether a parcel borders public land and what that means for access23. Only 48.1% of the county sits at 15% slope or less, and 45.9% is wooded, so plenty of land here is steep or rocky enough to complicate a driveway, septic field or building pad2425. Soils are a real constraint for septic too: just 5.7% are rated without severe limits for a conventional drain field4. The county has been in severe drought roughly 28.5% of years on record, with only about 16.7 inches of precipitation annually, so a water plan -- well yield, storage, or a hauling budget -- matters here2627. Typical home values run around $438,449, and the effective property tax rate is about 0.4% for a median annual bill near $1,357282930. If you're considering renting the property short-term, Colorado leaves short-term rental regulation to counties, so confirm Mesa County's current licensing rules before you count on that income31.

Watch-outs

  • We could not confirm a Mesa County owner-builder exemption from contractor licensing; ask the Building Division before assuming one applies1213.
  • Soils in Mesa County rate only 5.7% free of severe limits for a conventional septic drain field, so most rural parcels should budget for a site evaluation and likely an engineered or alternative system4.
  • Colorado's new statewide ADU mandate generally does not reach ordinary unincorporated rural land in Mesa County; it targets larger jurisdictions inside a metropolitan planning organization19.

    • Applicants must complete the appropriate application and pay the associated fee.
    • Statutory exemptions and additional Denver Basin or Designated Basin rules may affect the requirement or permit conditions.
    • In many areas, a well may also require an augmentation plan if its priority is not sufficient to divert in priority.

    complete-application review time: <= 49 days (DWR states review of complete new and replacement applications may take up to 49 days)

    “Every new well in the state that diverts groundwater must have a well permit.”
  • Mandatory utility hookupConditional

    Residential or other occupied structures statewide that are not serviced by a sewage treatment works.

    • Colorado law conditions building and occupancy permitting on either service by a sewage treatment works or an approved OWTS process.
