Building permits, zoning and land rules in Sedgwick County, Colorado

Unincorporated Sedgwick County requires a building permit before a building is erected, occupied, moved or structurally altered¹. The building-permit fee is $50 for structures costing $2,000 or more; cheaper structures still require an application but have no building-permit fee². Submit building plans and the requested property, zoning, use, builder, setback, cost and completion information². Inside Julesburg, apply to the town building inspector before building alterations; septic permits still come from Northeast Colorado Health Department^4,6. For local building rules inside Ovid or Sedgwick, the county directs applicants to the respective town clerk¹.

Sedgwick County Planning & Zoning handles the county building permit at the Assessor's Office, 315 Cedar St., Suite 200 in Julesburg; call 970-474-2531 or email assessor@sedgwickcountygov.net¹. Sedgwick County does not have a building code ordinance, and the county says it has no licensed building inspector^1,2. The county fee schedule also lists house-moving, subdivision-exemption, right-of-way and road-crossing applications; ask Planning & Zoning which apply to your project². We could not confirm who performs county building inspections or whether a certificate of occupancy is required, so ask Planning & Zoning before scheduling construction¹.

For unincorporated land, Sedgwick County administers zoning districts, including residential, agricultural, mobile-home, recreation, tourist, commercial, industrial, unclassified and commercial-highway districts³. Standard residential and mobile-home yards are 30 feet in front, 7 feet at the side and 20 feet at the rear, while supplementary rules and exceptions can change the result³. The Mobile Home district also caps building height at 30 feet; other district-specific height rules may apply³. Principal uses in agricultural districts generally require 2 acres, and residential minimum lot area varies with subdivision status and public water and sewer service³. Ask Planning & Zoning to identify the parcel's district and any special-use, subdivision or floodplain review before designing the site^1,3. Inside Julesburg, town zoning applies; Northeast Colorado Health Department remains the septic authority^5,6.

The Northeast Colorado Health Department issues Sedgwick County OWTS permits, including in unincorporated areas and municipalities within its district⁶. Sedgwick County requires the separate NCHD septic permit before construction to install, alter or repair a sewage-disposal system². NCHD also requires permits for expansion and generally cannot issue one where public sewer service is available unless service is infeasible or the sewer provider authorizes it⁶. Colorado requires a final inspection of the system by the local public health agency or its designated engineer after construction¹⁰. The published fee is $500 for either a new system or a repair⁷. A landowner of record may install one OWTS per year for private use without a Systems Contractor License, but the permit, department inspection and other OWTS rules still apply⁶. About 34.3% of county soils avoid a severe USDA limitation rating for a conventional drain field, so make the site evaluation an early contingency¹¹.

We could not confirm whether unincorporated Sedgwick County allows long-term RV occupancy on private land, so ask Planning & Zoning about the parcel and proposed duration before relying on an RV as housing^1,3. The county's campground provision covers overnight rather than weekly campground use in the Recreation district; it does not answer residential RV living on private land³. Colorado-regulated tiny homes intended for long-term living require state plan approval and must also satisfy local zoning⁸. A tiny home regulated as a dwelling unit under Sedgwick County zoning must contain at least 400 square feet of floor area measured at the outside walls; meeting that minimum alone does not establish approval for the parcel³.

1. Ask Planning & Zoning to confirm the parcel's zoning district, allowed dwelling type, setbacks, lot area and floodplain status³.
2. If the site will not use public sewer, obtain the OWTS permit from Northeast Colorado Health Department before installing the system².
3. If you need groundwater, apply to the Colorado Division of Water Resources for the well permit⁹.
4. Submit the county application with building plans and the requested site and project information².
5. If access connects directly to a state highway, secure the Colorado Department of Transportation access permit¹².
6. Ask Planning & Zoning what inspections and occupancy documentation apply because we could not confirm those requirements¹.

Start with zoning, legal access, flood exposure, water and septic feasibility. Sedgwick County limits construction in inundation areas and requires county-commissioner approval before covered structures are built there³. Direct access from a house to a Colorado state highway requires a state access permit¹². Every new groundwater-diverting well needs a state permit, subject to statutory and basin-specific exceptions⁹. Only 34.3% of county soils avoid a severe USDA limitation rating for conventional septic drain fields¹¹. The effective property-tax rate is about 0.5%, and the median annual property-tax bill is $671¹¹.
