Do you need a building permit in Logan County, Colorado?
Yes. Logan County requires a building permit for construction in unincorporated areas through the county's Planning, Zoning and Building Department in Sterling1. Site-built work receives footer, foundation, framing, drywall and final inspections; agricultural buildings, oil and gas operations, and some utilities are excepted from required county inspections but may be inspected on request17. Electrical and plumbing inspections are performed by the State of Colorado, and county inspection requests generally need at least 24 hours' notice18. A new building generally cannot be occupied until the county completes its final inspection and issues a Certificate of Occupancy; accessory structures are excepted19. Reach the department at 970-522-7879 or visit 315 Main Street, Suite 2, in Sterling2.
Who is the Logan County building department and how do you reach them?
The Logan County Planning, Zoning and Building Department is at 315 Main Street, Suite 2, in Sterling2. Office hours are 8 to 5 Monday through Friday except holidays2. Call 970-522-78792. The department's official page provides building, zoning-use, variance, floodplain-development and right-of-way applications2201021. Published county fees vary by application; a county right-of-way driveway request costs $50 and goes through Planning and Zoning to the Board of County Commissioners2212. Some zoning-use applications require submission at least 20 days before the Board of Adjustment hearing, plus public, posted and nearby-owner notice, so ask the department which review path applies before setting a construction schedule23.
Does Logan County have zoning?
Yes. Logan County zoning applies outside incorporated cities and regulates unincorporated land by district; municipal zoning may apply inside a city38. The published districts are EP, A, RE, RS, RM, CH, CC and I, and the use grid classifies uses as by right, conditional or subject to a special-use permit24. Minimum lot size, setbacks and height limits vary by district and use252627. A zoning permit is also required before a utility is built, installed, hooked up or placed in service unless an approved variance applies28. Ask the Planning, Zoning and Building Department to identify the parcel's district and applicable use and dimensional standards before fixing a site plan20.
How do septic permits work in Logan County?
Any building in Logan County that creates wastewater flow and is not connected to a city sewer system needs an onsite wastewater treatment system (OWTS), or septic, permit from the Northeast Colorado Health Department, and any new system or repair of an existing one requires that permit before work begins69. NCHD's office for this program is at 700 Columbine Street in Sterling, reachable at (877) 795-06466. Soils here are relatively favorable by the standards of this dataset: about 43.9% of Logan County's soils are rated without severe limitations for a conventional septic drain field, well above many rural counties, though that still leaves more than half the county where a standard system may not work and a site evaluation matters29. Colorado law backs this permit requirement statewide: no one may construct, alter, install or use an OWTS without first applying for and receiving a permit from the local public health agency, and a final inspection is required before the system can be placed in use3031. A building permit for a home not served by a sewage treatment works cannot move forward until the OWTS permit is issued, and occupancy approval waits on the final septic inspection, so plan your septic application early32.
Can you live in an RV or tiny home on your land in Logan County?
Colorado permits a Division of Housing-approved tiny home to be used as a long-term residence only after its plans receive state approval and the home complies with local zoning15. We could not confirm a Logan County rule that clearly resolves tiny-home or private-land RV occupancy, so ask the Planning, Zoning and Building Department about the parcel's district before placing either unit20. In specified districts, a manufactured home used as temporary living quarters while a permitted house is built requires a Zoning Use Permit; the permit expires after 365 days unless renewed in exceptional circumstances, and the unit must be removed within 30 days after the house receives its Certificate of Occupancy33. County rules separately limit stays in regulated camping areas to three consecutive months, but that provision does not establish a general right to camp on any private parcel34.
Building a home in Logan County: the steps, in order
- Confirm the parcel's zoning district, allowed residential use, minimum lot size and setbacks with the Logan County Planning, Zoning and Building Department at 970-522-787922526.
- Apply to the Northeast Colorado Health Department for an OWTS permit if the home will not connect to municipal sewer; building approval and occupancy depend on septic approval and final inspection632.
- Apply to the Colorado Division of Water Resources if the project needs a new groundwater well14.
- Submit the building-permit application and determine whether flood-hazard-area development also requires county floodplain approval135.
What to check before you buy land in Logan County
Confirm the zoning district and allowed use before buying because Logan County applies district-specific use, setback, height and minimum-lot-size standards8252627. A proposed land split may require one of the county's published subdivision review processes36. Arrange a septic evaluation because only 43.9% of county soils are rated without severe limitations for a conventional drain field29. Check the flood map because development in a county flood-hazard area requires a permit35. Confirm legal and physical access because county right-of-way driveway requests need approval12. Logan County receives about 16.2 inches of precipitation annually and experiences severe drought in about 19.3% of years, making water planning especially important3738.
Watch-outs
- Logan County has adopted zoning outside incorporated cities, so do not assume a rural parcel is unrestricted; confirm the district and its use, setback and dimensional rules before planning a build78.
- We could not confirm a general right to live in an RV on rural Logan County land; ask the Planning, Zoning and Building Department before relying on RV occupancy20.
- Only 43.9% of Logan County's soils are rated free of severe limitations for a conventional septic drain field, so budget for a site evaluation before assuming a standard system will work29.
