Does Frisco, Colorado have zoning, and what does it mean for lot size and setbacks?

Yes. The Town of Frisco adopts zoning districts in its Unified Development Code, Chapter 180, and that code applies to land inside town limits1. We reviewed two residential districts; the town's other districts are not covered here9.

In the Residential Traditional Neighborhood (RN) district, a detached single-household lot must be at least 3,000 sq ft and no more than 7,000 sq ft5. Setbacks are 10 ft front and 10 ft rear for the main building10. Maximum lot coverage is 70%11 and maximum height is 30 ft6.

In the Residential Low Density (RL) district, the minimum lot is 10,500 sq ft4. Setbacks are 20 ft front, 15 ft side and 10 ft rear12, coverage tops out at 50%13, and height is capped at 30 ft7. Find your parcel's district with the Community Development Department before you make an offer2.

Do you need a building permit in Frisco, and who issues it?

Inside Frisco town limits, the town's Community Development Department handles permits: its building and planning divisions help customers obtain permits for development and give zoning information on properties2. The department takes both planning and building permit applications online through CommunityCore2.

Planning review and building review are separate tracks, so a new home or an addition can need both. We could not confirm Frisco's building code edition, permit fees, inspection steps or owner-builder rules; ask the Community Development Department at 970-668-52762.

Summit County's Building Inspection Division serves unincorporated land, so the county's permit rules do not govern a lot inside Frisco. For land outside town limits, see the Summit County guide.

How do septic permits work in Frisco, Colorado?

Summit County, not the town, runs the septic permit program: the Environmental Health Department issues onsite wastewater treatment system (OWTS) permits and inspects new installations and repairs across Summit County3. Colorado requires an OWTS permit from the local public health agency whenever a building is not served by a sewage treatment works14. Contact Summit County Public Health at (970) 668-916115.

We could not confirm whether a particular Frisco lot is on public sewer or would need a septic system; ask the Community Development Department and Environmental Health before you buy.

Soil matters too. Only 2.6% of Summit County's soils are rated not limited for a conventional drain field, so a septic lot usually needs a site evaluation and often an engineered system16.

Can you live in an RV or tiny home on a lot in Frisco?

We could not confirm whether Frisco allows RV living or camping on a private lot, or how it treats tiny homes. The town's camping rules we reviewed cover town parks and the Dillon Reservoir area, not private property. Ask the Community Development Department before you buy a lot with that plan2.

One rule is confirmed. In a Special Flood Hazard Area inside Frisco, an RV must be on site fewer than 180 consecutive days or be ready for highway use17. Accessory dwelling units are permitted in the RL district within the same building and alongside a principal dwelling, as stated in the district's criteria for developments of three or more units; other ADU rules were not reviewed18.

Building a home in Frisco: the steps, in order

  1. Confirm your parcel's zoning district and its lot, setback, coverage and height limits with the Community Development Department2.
  2. Check whether the lot is in a Special Flood Hazard Area; a new home there needs its lowest floor one foot above base flood elevation17.
  3. Ask whether the lot is served by public sewer; if not, apply to Summit County Environmental Health for an OWTS permit3.
  4. If you plan a well, Colorado requires a permit for every new groundwater well8.
  5. File planning and building permit applications online with the town2.

What stays with Summit County, and what to check before you buy in Frisco?

Septic permits stay with Summit County Environmental Health3, and well permits come from the state8. Land outside Frisco's limits falls under the county rules on the Summit County page.

For a sense of cost, Summit County's typical home value is about $985,00019 and the effective property tax rate is 0.3%20. Typical home insurance runs about $3,071 a year21. These are county-level figures, not Frisco-only.

Watch-outs

  • Frisco's building code edition, permit fees and owner-builder rules were not confirmed; ask the Community Development Department at 970-668-52762.
  • Only two of Frisco's residential districts were reviewed, so confirm your parcel's district and its standards with the town9.
  • Septic permits come from Summit County Environmental Health even for a lot inside Frisco; confirm sewer service before you buy3.
  • A lot in a Special Flood Hazard Area needs its lowest floor one foot above base flood elevation17.
