Do you need a building permit in the Town of Bayfield, Colorado?

Yes. A building permit must be obtained before covered work begins inside Bayfield town limits.1 Even when the project falls outside the building-permit requirement, the Bayfield Land Use Code still applies.1 Bayfield has adopted the 2018 International Residential Code, subject to town amendments, along with related international codes and the current electrical code identified by the Town.5

The Town of Bayfield Building Division, rather than La Plata County's unincorporated-area building office, handles in-town construction permitting and inspection.2 Submit the applicable application packet and plans before work, and allow at least 20 business days for review; resubmittals extend that timeline.9

Who issues building permits in the Town of Bayfield?

The Town of Bayfield Building Division issues building permits and inspects construction and development projects within town limits.2 Applications go to [email protected], and the Building Division can be reached at 970-884-9544 ext. 212 at Town Hall, 1199 Bayfield Parkway.2

New residential and commercial or multifamily projects require digital plan submittals.9 Deposits are due with the application, while the remaining fees are due after reviews are complete and the building permit is issued.9 Required inspections should be scheduled with at least 48 hours' notice.9 After residential permit work is complete, final inspections, payment of outstanding charges and a Public Works final inspection precede the Town's certificate of occupancy.10

Does the Town of Bayfield have zoning?

Yes. Bayfield applies its own Land Use Code inside town limits, including zoning, height, setback and landscaping requirements during building review.3 Those requirements can apply even when a building permit is not required.1 Ask the Community Development Department to identify the parcel's zoning district and any additional planning process before submitting building plans.3

The Town's confirmed accessory-dwelling standard sets a minimum floor area of 300 square feet; an accessory dwelling unit is also capped at the lesser of 700 square feet or half of the primary residence's floor area.8 That accessory-unit rule is not a minimum size for every principal home.8 We could not confirm complete district-specific lot size, setback, lot coverage or height figures, so obtain the parcel-specific standards from Community Development before relying on a listing or sketch.3

How do septic permits work inside the Town of Bayfield?

La Plata County Public Health Department is the onsite wastewater authority throughout La Plata County, including properties inside Bayfield that use an onsite system.4 A county septic permit is required before constructing, altering or repairing an onsite wastewater treatment system.6 Applications may be emailed to the OWTS team or delivered to the Public Health office.6

Only 5.1% of La Plata County soils are rated without severe limitations for a conventional septic drain field, so an unsewered site's soil evaluation belongs early in the buying and design process.11 Most septic-served properties in La Plata County also require an inspection before sale, subject to listed exemptions.12 Contact the county OWTS team at 970-828-8842 or [email protected].13

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

Bayfield lists recreational vehicles as a temporary use in all zoning classifications, requires a temporary-use permit, and sets the stated temporary RV period at 7 days.7 Approved campgrounds and mobile-home-permitted districts are treated as exceptions to that temporary-use entry.7 The confirmed rule does not establish a right to use an RV as a permanent residence, so ask Community Development about the parcel, proposed duration and utility arrangement.3

Colorado approves qualifying tiny homes for long-term living only when they meet state requirements and local zoning.14 Bayfield publishes a tiny-home building-permit category, but we could not confirm the complete occupancy, dimensional and siting rules for a tiny home inside town limits; ask both Community Development and the Building Division before buying or ordering a unit.32

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

  1. Ask Bayfield Community Development to confirm the parcel's zoning district, allowed dwelling type and any planning approval needed before the building application.3
  1. Design to Bayfield's adopted 2018 residential code and town amendments.5
  1. If the site will use an onsite wastewater system, obtain the required La Plata County septic approval before construction of that system.6
  1. Submit the completed Town application and digital plans, pay the deposit, and allow at least 20 business days for review.9
  1. Obtain the building permit before starting covered work and schedule inspections at least 48 hours ahead.19
  1. Complete final inspections, settle outstanding charges and obtain the Town's certificate of occupancy before treating the home as complete.10

What should you check before buying land in the Town of Bayfield?

Confirm that the parcel is inside Bayfield town limits, then have Community Development identify its zoning district and applicable use, setback, lot, height and planning requirements.3 Ask the Town whether municipal water and sewer serve the site; if an onsite wastewater system is proposed, contact La Plata County Public Health before assuming the soil can support a conventional drain field.1311

For mapped special flood hazard areas, Bayfield requires compliance with its flood-damage rules; where base-flood-elevation data exists, residential construction must elevate the lowest floor and service facilities at least 1 foot above base flood elevation.15 Direct access from a house to a state highway requires a Colorado access permit.16 We could not confirm Bayfield-specific rules for a private well or an ordinary in-town driveway, so ask the Town and the applicable water or road authority before closing.3

Watch-outs

  • Do not use La Plata County's unincorporated-area building or zoning rules for a parcel inside Bayfield; the Town handles in-town building and planning review, while the county handles onsite wastewater.234
  • Bayfield's 7-day temporary RV provision does not establish permanent RV occupancy on an ordinary parcel.7
  • A Colorado-approved tiny home must still satisfy local zoning, and Bayfield's complete tiny-home occupancy and siting rules remain unconfirmed.143
