Do you need a building permit in Fraser, CO?

Yes. Building work inside the Town of Fraser needs a building permit¹. The exemptions are narrow: one-story detached accessory structures up to 120 sq ft, fences up to 6 ft, at-grade walks and driveways, and agricultural buildings¹. Separate plumbing, electrical and mechanical permits are still required for exempted items unless they are otherwise exempt¹.

Fraser builds under the 2021 International Residential Code with local amendments¹³. The permit application must include documentation from the Water and Sanitation District of an approved water and sewer utility plan, which may mean paying tap fees¹⁴. New foundations need an Improvement Location Certificate and a Setback & Elevation Certificate before the rough framing inspection, and a permit expires 24 months after issue unless work starts within 180 days¹⁵. Fraser also charges a 4% municipal use tax on building materials bought without Fraser sales tax³.

We could not confirm whether Fraser offers an owner-builder exemption or what the permit fees are; ask the Winter Park-Fraser Building Division¹⁶.

Who issues building permits in Fraser, and how do you reach them?

The Town of Fraser and the Town of Winter Park operate a combined building department through an intergovernmental agreement³. Winter Park administers building permits, plan review and inspections on behalf of Fraser³. Fraser Town Hall does not run its own building department³.

Contact the Winter Park-Fraser Building Division at 970-726-8081 or [email protected], and include the full address with the town and a short description of the work¹⁶. Zoning questions go to the Town of Fraser Planning & Zoning Department, which administers the Fraser Land Development Code¹⁷. Septic is a separate office, covered below.

These are Fraser rules. For land outside town limits, use the Grand County page, where the county runs its own building and zoning offices.

Does Fraser have zoning, and what are the lot sizes and setbacks?

Yes. Fraser administers its own zoning, with districts that include OS, RD, LDSF, LDMF, MDSF, MDMF, HDMF, B, RW and TI². Always find the district for the exact parcel first, because the numbers change by district.

In the Rural Density District (RD), the minimum lot area is 2 acres and the minimum lot width is 200 ft¹⁸, with setbacks of 30 ft front, 10 ft side and 20 ft rear¹⁹. In the Low Density Single-Family district (LDSF), the minimum lot is 6,000 sq ft and 50 ft wide²⁰, with setbacks of 20 ft front, 7 ft side and 10 ft rear²¹. In the Medium Density Single-Family district (MDSF), a detached house needs 5,000 sq ft²², with a 20 ft front setback and 10 ft rear setback²³.

A 30 ft stream setback applies in these districts, and review can require up to 150 ft¹⁹. Maximum height is 35 ft in RD, LDSF and MDSF²⁴. The principal structure must be at least 500 sq ft in each of those districts⁸.

Can you live in an RV or tiny home in Fraser?

RV living is limited in Fraser. RV occupancy inside the town is allowed only in permitted campgrounds and RV parks, which are conditional uses⁶. Stays may not exceed four weeks, and each space must be at least 500 sq ft and 20 ft wide with a central water supply and sewage disposal system⁶. We found no Fraser rule that lets you live in an RV on a residential lot, so ask the Planning & Zoning Department before parking one on land you own¹⁷.

We did not find a tiny-home provision in the Fraser code. A tiny home built as a dwelling still has to meet the 500 sq ft minimum floor area in RD, LDSF and MDSF⁸.

An accessory dwelling unit may be approved as listed on the Schedule of Uses⁷. It must be at least 200 sq ft and no larger than 50% of the principal dwelling or 1,200 sq ft, whichever is less, with a kitchen, bathroom and separate entry⁷. An ADU may be licensed as a short-term rental, but the ADU and the main house cannot both be licensed²⁵.

How do septic permits and wells work in Fraser?

We could not confirm who issues septic permits inside Fraser town limits. Colorado requires a permit to build or alter an onsite wastewater system for any structure not served by a sewage treatment works⁴, and a Fraser building permit application must show an approved water and sewer plan from the Water and Sanitation District¹⁴. Ask the district whether your lot can connect to sewer before planning a septic system.

In unincorporated Grand County, the county Building & Sanitation Division acts as the Sanitarian, reviewing designs, issuing permits and conducting field inspections under the county onsite wastewater regulations²⁶. Call it at 970-725-3255 to confirm whether it handles any address in Fraser²⁶.

If you will use a septic system, note that only 3.4% of soils in Grand County rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system²⁷. Every new well in Colorado needs a state well permit, subject to exemptions¹².

How do you build a home in Fraser? The steps, in order

Confirm the zoning district and lot standards for the parcel with the Planning & Zoning Department¹⁷.

What stays outside Fraser, and what should you check before you buy?

Fraser's rules apply only inside town limits. Land outside the town falls under Grand County, which has its own answers on the Grand County page.

Inside mapped flood hazard areas with base flood elevation data, new construction must have the lowest floor elevated 1 ft above base flood elevation¹¹. A driveway directly onto a Colorado state highway needs a state access permit²⁸.

Grand County's effective property tax rate is 0.3%²⁹, and the median property tax bill is $1,763 a year³⁰; those figures are county-wide, not specific to Fraser.
