Do you need a building permit in Moffat County, Colorado?
Yes. Moffat County requires a building permit for a structure larger than 200 square feet, a fence higher than 6 feet or a retaining wall greater than 4 feet1. The county administers the 2018 International Codes11. A building used exclusively to shelter agricultural implements, farm and ranch products, livestock or poultry may qualify for an agricultural exemption, but storage for passenger or recreational vehicles, unrelated construction equipment and workshops does not qualify12. Before occupying a completed home or business, the owner must obtain a certificate of occupancy; the basic conditions include approved electrical and sewage systems, working plumbing and heat, a posted address and no hazardous condition in the occupied area13.
Who is the Moffat County building department, and how do you reach it?
The Craig/Moffat Regional Building Department handles Moffat County building-permit information and also issues county septic permits1415. Call 970-826-2013 or email [email protected]; published office hours are 8:00 AM-5:00 PM15. The Planning & Zoning Department is the separate first stop for a parcel's district, allowed uses, setbacks and land-use applications7. Its office is at 1198 W. Victory Way, Ste. 107 Craig, CO 81625, and its phone number is (970) 824-91487. For a driveway that connects to or affects a county road, the Road and Bridge Department issues the required permit from 822 E. 1st Street1617.
Does Moffat County have zoning?
Yes. The Moffat County Zoning Resolution covers county zoning requirements, while the rules for uses, setbacks, lot size, conditional uses, variances and zone changes depend on the applicable district3. For example, the Agriculture District has a 5-acre minimum lot size, while the Rural Residential District requires 3 acres with individual water and septic, 2 acres with either community water or sewage, and 1 acre with both community water and sewage18. Dwelling-size rules also vary by district; the cited district provision sets a 200-square-foot minimum rather than establishing one countywide minimum19. Setbacks are likewise district-specific, so have Planning & Zoning confirm the parcel's designation and standards before choosing a building site57.
How do septic permits work in Moffat County?
Moffat County requires a septic permit, charges a $100 permit fee and requires septic systems to be engineered; the Craig/Moffat Regional Building Department issues the permit46. The building application plot plan must show the well, septic system, proposed construction and property-line distances, with at least 100 feet between a well and the septic system or leach field20. Colorado also requires a final on-site wastewater inspection after permitted work is complete and before the system is used, and approval is required before an OWTS-served building receives occupancy approval21. Only 23.2% of county soils are rated without severe limitations for a conventional drain field, so site suitability and engineering can materially shape the project22.
Can you live in an RV or tiny home on your land in Moffat County?
We could not confirm a countywide Moffat County rule for long-term RV occupancy or private-land camping, so ask Planning & Zoning about the specific parcel and proposed duration before moving an RV onto the site7. The agricultural building exemption does not turn RV storage or use into an exempt agricultural purpose12. Colorado approves qualifying tiny homes for long-term living on permanent or temporary foundations, but plans must receive state approval before construction and the unit must still satisfy local zoning8. Moffat County's minimum dwelling area is district-specific, with a cited 200-square-foot standard in specified districts rather than one rule for every parcel19. Confirm the zoning district, allowed dwelling type and occupancy path with Planning & Zoning before ordering a unit7.
Building a home in Moffat County: the steps, in order
- Ask Planning & Zoning to identify the parcel's district, allowed residential use, minimum lot size and setbacks37.
- Confirm legal access; a driveway affecting a county road requires a Road and Bridge permit, while direct access to a state highway requires a CDOT access permit1623.
- Apply to the state Division of Water Resources before drilling a new groundwater well10.
- Have the septic system engineered and obtain the $100 county septic permit4.
- Submit a signed building application, two sets of building plans and a plot plan showing buildings, well, septic, proposed work and property-line distances20.
- Complete required inspections and obtain the certificate of occupancy before moving into the home13.
What should you check before buying land in Moffat County?
Start with water, septic feasibility, legal access, zoning and flood exposure. Every new groundwater well needs a state permit, while county septic permitting requires engineering104. The county averages 14.9 inches of precipitation annually and has experienced severe drought in 26.5% of years, so verify the realistic water source and yield before relying on a homesite2425. About 51.9% of the land has a slope of 15% or less, and only 23.2% of soils are rated without severe limits for a conventional drain field2622. About 57.2% of Moffat County is federal land, so verify recorded access rather than assuming an adjoining public route serves the parcel27. Floodplain development standards apply where mapped hazards affect the site; ask the building office to confirm the local review path2815.
Watch-outs
- A building used to store recreational vehicles or to serve as a workshop does not qualify for Moffat County's agricultural building-permit exemption12.
- Only 23.2% of Moffat County soils are rated without severe limitations for a conventional septic drain field, and the county requires engineered septic systems224.
- Moffat County requires a certificate of occupancy before anyone moves into a home or business13.
- We could not confirm the county's private-land RV occupancy rule; ask Planning & Zoning before using an RV as a residence7.
