Do you need a building permit in the Town of Hayden, CO?

Hayden sends building and trade permit applications to the Routt County Regional Building Department, which serves residential and commercial buildings and structures inside town limits.8 The department reviews building, electrical, mechanical, gas, plumbing, deconstruction, solar, sign, pool/spa/hot tub, and grade and fill permits.8 Hayden contracts with the regional department for inspections as well as building permits.1 Ask that department which approvals your specific project needs before scheduling work.8

Who handles Town of Hayden building permits and zoning?

Start zoning and development questions with Town of Hayden Planning and Zoning; the Hayden Development Code guides development within town limits.1 Start building applications by registering on the Regional Building Department website, completing the application and submitting draft plans online.1 Town Hall can help with completing the building application.1 Hayden keeps its adopted building and trade permit fee schedule on file with the town clerk; the reviewed code section does not supply dollar amounts, so request the current schedule for your project.9

Does the Town of Hayden have zoning for ADUs and small homes?

Hayden applies its own Development Code inside town limits.1 Hayden allows accessory dwelling units in any zone district when the applicable standards are met, on lots with an existing single-family dwelling and on the same lot or a contiguous lot under the same ownership.6 Hayden limits an ADU to 800 square feet of habitable space and no more than one ADU per lot.6 We could not confirm Hayden’s minimum dwelling size, lot size or principal-home setbacks; ask town Planning and Zoning for the parcel’s district standards before choosing a house plan.1

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

Hayden’s residential temporary-camping provision covers RVs, travel trailers, pop-up campers and tents, but the site must be associated with a permitted permanent residential structure.10 Hayden permits temporary camping for no more than 14 consecutive days per permit, with an annual maximum of 42 days and only one camping permit per residential lot or site at a time.5 Colorado Division of Housing-regulated tiny homes may be approved for long-term living, but must meet state standards and local zoning requirements.11 We could not confirm where Hayden allows tiny-home occupancy; ask town Planning and Zoning about the proposed unit and address.1

How do septic permits work inside the Town of Hayden?

Colorado requires an OWTS permit from the applicable local public health agency for construction, alteration, installation, repair or use of a septic system where a building is not served by sewage treatment works.3 Routt County Environmental Health runs a program issuing permits for construction, use and repair of on-site wastewater treatment systems.4 We could not confirm that program’s jurisdiction for every Hayden address; ask Environmental Health to confirm the permitting authority, and ask town Planning and Zoning about the proposed property’s sewer arrangements before budgeting for septic.41

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

  1. Ask Hayden Planning and Zoning to review the proposed use under the town’s Development Code before settling on a design.1
  2. Address flood constraints early: Hayden requires residential new construction and substantial improvements in special flood-hazard areas to meet its elevation standard where base-flood data are provided; floodway encroachments require an engineer’s no-increase certification.12
  3. Resolve wastewater approval with the applicable local public health agency if the building will not be served by sewage treatment works.3
  4. Register with the Regional Building Department, complete the building application and submit draft plans online; that department also performs Hayden inspections.1

For a property outside town limits, use the Routt County guide: the county’s Unified Development Code governs unincorporated land.2

Watch-outs

  • Hayden temporary residential camping requires a site associated with a permitted permanent residential structure; do not assume the camping provision allows living on a vacant lot while building.5
  • Hayden prohibits using a mobile home, recreational vehicle or travel trailer as a short-term rental.13
  • We could not confirm a Hayden owner-builder exemption or certificate-of-occupancy requirement; ask the Regional Building Department before planning owner-performed construction or moving in.1
