Rollinsville has no town government and no building department. It is a census-designated place of 194 people at 8,668 feet, and every permit for every project here goes through the Gilpin County Building Division in Central City. That makes it one of the more straightforward permitting situations in the county — and one of the more complicated development situations, for a reason that has nothing to do with permits.
Who Permits Your Project in Rollinsville
All construction permitting for Rollinsville runs through Gilpin County Community Development, in the Old Courthouse at 203 Eureka Street in Central City. Since March 1, 2023 the county has issued all permits directly. Inspections are scheduled on Mondays and Wednesdays; septic inspections run Tuesdays and Thursdays. Every contractor is required to register with Community Development before applying for a permit or performing work — a step that catches out-of-county contractors regularly.
Because there is no municipal layer here, there is also no local design review and no second approval to sequence. The county’s process is the whole process. The tradeoffs are the county’s timelines: applications submitted after September 1 may not be approved before frost, which effectively sets the deadline for starting a season’s work.
The Water Constraint in the Commercial Core
Rollinsville’s commercial core does not have sufficient water capacity for firefighting. Timberline Fire Chief Paul Ondr put it plainly: “We basically have a commercial area with no water available for fire fighting.” Gilpin County, with JVA Consulting Engineers, has been running a Rollinsville Infrastructure Study and Area Specific Plan — projecting roughly 3,300 gallons per day of train-rider use and about 9,000 gallons per day of residential use — because development in the commercial core cannot move forward without a water solution.
For a residential owner this matters in two ways. It signals that infrastructure here is thin and that new service connections are not assumptions to make. And it means projects on or near the commercial corridor may face questions that a similar project a few miles away would not. We check the specific parcel’s water and wastewater situation before scoping, rather than after.
A Small, Spread-Out Community on 1.4 Square Miles
Rollinsville covers 904 acres — about 1.412 square miles — with a population of 194 as of 2020, up from 181 in 2010, a 7.2% increase. That works out to roughly 137 people per square mile: rural density on a small footprint, at an elevation of 8,668 feet, in ZIP code 80474.
Housing here is a mix of older mountain construction and newer builds on acreage, with most parcels on private well and onsite wastewater rather than municipal service. Gilpin County requires a septic inspection and a Use Permit before a property transfers in the unincorporated county, and adopted Colorado Regulation 43 in its entirety plus local additions effective March 13, 2026. Most private property in the county is zoned rural residential or residential suburban, allowing one primary dwelling plus one accessory dwelling unit per parcel — which is the governing constraint on anyone thinking about adding a second living space.
Building Conditions at 8,668 Feet
Gilpin County adopted the 2024 International Codes effective April 1, 2026, along with the 2024 IWUIC with local amendments and the 2025 Colorado Wildfire Resiliency Code. Most of the county is wildland-urban interface: 30 feet of defensible space for new construction, ignition-resistant materials, reflective address markers, and Class F or better roofing. Prescriptive residential design is generally insufficient here, so a licensed structural engineer is involved in almost every project. A driveway permit is required before grading and must be posted at the entrance, and a grading permit is triggered at 3,000 square feet of disturbance or more than 50 cubic yards.

Common Questions
Who issues permits in Rollinsville?
Gilpin County Community Development, at 203 Eureka Street in Central City. Rollinsville is an unincorporated census-designated place with no town government or building department, so there is no municipal permit and no local design review — the county process is the entire process.
Can I add an accessory dwelling unit?
Most private property in Gilpin County is zoned rural residential or residential suburban, which allows one primary dwelling and one accessory dwelling unit per parcel. Whether a specific parcel can support one also depends on the septic system’s capacity and the well, which are usually the real limits rather than the zoning.
Do I need a septic inspection before selling?
Yes. Gilpin County requires a septic inspection and a Use Permit before a property transfers in the unincorporated county. Septic inspections are scheduled Tuesdays and Thursdays. Owners who leave this to the last two weeks of a transaction are the ones who end up paying for expedited repairs.
Does my contractor need to be registered?
Yes. Gilpin County requires all contractors to register with Community Development before applying for permits or performing work. This is checked, and it is a common reason an out-of-county contractor cannot start when promised.
Is there a deadline for starting work in a given year?
Effectively, yes. The county advises that applications submitted after September 1 may not be approved before frost. At 8,668 feet, that is a real constraint on foundation and excavation work, and it makes early submittal the difference between building this year and next.
