Who handles building applications and zoning questions in the Town of Julesburg?

Does the Town of Julesburg have zoning, minimum lot sizes and setbacks?

Julesburg has its own zoning, with district-specific use, lot, dwelling-size and setback rules; confirm the parcel’s district before choosing a house plan.² In Julesburg’s A district, a one-family dwelling needs a lot of at least 6,000 square feet and a dwelling area of at least 850 square feet, measured outside.⁷⁵ In the B district, a one-family residence needs at least 4,500 square feet of lot area; a residence with a basement apartment for two families needs 6,000 square feet.⁸ Ask the town building inspector for the setbacks that apply to the actual district and proposed structure.²

How do septic permits work inside the Town of Julesburg?

Northeast Colorado Health Department’s onsite wastewater rules cover municipalities within Sedgwick County, including Julesburg.³ Where a municipality or special district provides public sewer service, a septic permit generally cannot be issued unless service is infeasible or the municipality or district authorizes it.³ Ask about sewer service before budgeting for a septic installation.³ For an eligible onsite system, NCHD requires a plot plan and a site evaluation to determine suitability and system size.¹³ Colorado law requires onsite wastewater approval before building or remodeling approval for a structure without sewage-treatment service, and final system inspection and approval before occupancy approval.¹⁴

Can you live in an RV or tiny home in the Town of Julesburg?

We could not confirm a general rule allowing RV living or temporary camping on a private Julesburg lot; ask the town building inspector about the proposed use and district before buying an RV for housing.¹² A Colorado Division of Housing-regulated tiny home intended for long-term living must satisfy state approval requirements and local zoning.⁹ Julesburg’s A district requires a one-family dwelling of at least 850 square feet, outside measurement.⁵ Julesburg’s A-1 district requires at least 1,400 square feet, outside measurement, a pitched roof of at least 4:12 and a garage or an equivalent approved by the building inspector.⁶ State tiny-home approval therefore does not by itself establish that a small unit fits either district’s dwelling requirements.⁹⁵⁶

What are the steps to building a home in the Town of Julesburg?

1. Ask the town building inspector to confirm the zoning district, permitted dwelling type, lot requirements and setbacks for the parcel.²
2. Resolve wastewater service: if public sewer is unavailable and an onsite system is eligible, obtain NCHD’s septic approval before building approval.³¹⁴
3. Contact the town building inspector about the building application and obtain the required building permit before covered work begins.¹⁰
4. Ask the town inspector which final inspections and occupancy documents your project requires; we could not confirm a general town certificate-of-occupancy requirement.¹²

For a proposed private groundwater well, Colorado’s Division of Water Resources administers well permits, with exemptions and basin-specific rules affecting the answer.¹⁵

Watch-outs

• Julesburg’s district-specific dwelling requirements still apply to state-approved tiny homes.⁹⁵⁶
• NCHD publishes revised onsite wastewater regulations effective 6/15/2026; ask NCHD which current requirements and fees apply before filing.¹⁶
• We could not confirm a town owner-builder exemption; ask the Julesburg building inspector before treating owner-performed work as exempt from building approval.¹²
