Does Town of Yampa have zoning and setbacks?

Town of Yampa has its own Land Development Code and zoning map governing land inside town limits.2 In Yampa’s O Open District, minimum yards are 50 feet front, 15 feet side and 25 feet rear; accessory buildings and ADUs have five-foot minimum side and rear setbacks.13 Those dimensions describe the O Open District, so ask the Town Planner to identify the parcel’s district before laying out a building.1311 Yampa allows an ADU only as an accessory to a single-family dwelling, with applicable dimensional, building, architectural and parking standards and a maximum habitable floor area of 1,000 square feet.8

How do septic and water connections work in Town of Yampa?

Town of Yampa prohibits on-site wastewater treatment systems inside town limits.4 All development in Yampa must connect to the Town’s central water distribution and wastewater systems; improvements to those systems require an improvements agreement.3 A septic system therefore cannot substitute for the required Town sewer connection on a Yampa development parcel.43 Start water and sewer connection questions with Town Hall.14 For a parcel outside Yampa in unincorporated Routt County, septic permitting goes through Routt County Environmental Health.15

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

An RV on any Yampa lot, parcel or tract cannot be inhabited for any period without adequate sewage disposal consistent with the Town’s land-development standards.6 Yampa RV parks require site-plan review and approval, and each RV space must connect directly to sanitary sewer.6 Adequate sewage disposal alone does not establish permission for permanent RV living; ask the Town Planner about your proposed use and duration.611 We could not confirm a Yampa-specific tiny-home occupancy rule or general minimum dwelling size; ask the Town Planner before choosing a design.11 Yampa allows manufactured homes conditionally, requiring state approval or Town-adopted IRC compliance, permanent foundation attachment and residential design standards.7

Building a home in Town of Yampa: what are the steps?

  1. Ask the Town Planner to confirm the parcel’s zoning and applicable development standards.211
  2. Arrange Town water and sewer connections, including an improvements agreement for system improvements.3
  3. For floodplain development, submit the required application to Yampa’s Town Floodplain Administrator.16
  4. Submit the construction application electronically to the regional building department with construction documents, a special-inspection statement, geotechnical report and other required data; the Building Official may waive materials unnecessary for code-compliance review.121
  5. Schedule building inspections through the county CityView portal and ask the regional department about final occupancy approval.10

What should you check before buying land in Town of Yampa?

Before buying a Yampa parcel, ask the Town Planner to confirm the district and whether your proposed home, ADU or manufactured home meets Town standards.287 Ask Town Hall about water and sewer connection arrangements because Town development requires both connections and septic systems are prohibited.1434 Floodplain development requires an application to the Town Floodplain Administrator, who reviews applications and inspects development during construction.16 We could not confirm Yampa-specific owner-builder, agricultural building exemption or general private-driveway permit requirements; ask the regional building department and Town Planner before relying on an exemption or access plan.1011

Watch-outs

  • Yampa’s Town water and sewer requirements and septic prohibition apply inside town limits; county septic rules do not provide an alternative sanitation route for Town development.34
  • Yampa’s RV sewage-disposal rule is a necessary condition for habitation, not confirmation that permanent RV occupancy is permitted on a particular parcel; ask the Town Planner.611
  • O Open District setbacks are district-specific; confirm the parcel’s zoning with the Town Planner before using those dimensions.1311
