Do you need a building permit in Dolores County, Colorado?

Dolores County is identified as not requiring a general building permit and has no county building department.1 We could not confirm the rule for every ordinary residential project, the adopted residential code, general inspections or a certificate of occupancy. Ask the Dolores County Board of County Commissioners to confirm the answer for the parcel and project before ordering materials. Colorado leaves most building-code adoption and land-use decisions to local government rather than imposing one uniform process on ordinary private projects.9 Separate approvals can still control the job: county land-use review may require water, wastewater, access, floodplain and development-improvement approvals.2

Who handles building and land permits in Dolores County?

Dolores County does not list a county building department, so start with the Board of County Commissioners for land-use and subdivision questions.1 The Board acts as the Board of Health and adopts subdivision regulations; its office is at 409 N. Main St. in Dove Creek and can be reached at 970-677-2383.10 The Assessor's Office says an Improvement Notice must be completed before any construction and returned with the applicable fees.11 That notice covers new homes, businesses, manufactured homes, additions and agricultural buildings.11 The notice is not proof that a general residential building permit or inspection is required, so ask the Commissioners which project approvals apply and use the Assessor for the Improvement Notice.1

Does Dolores County have zoning and land-use rules?

Yes. Dolores County has adopted development and land-use regulations and reviews land-use changes in the county.3 Residential subdivisions and mobile-home parks or subdivisions in unincorporated Dolores County require preparation, review and approval under county regulations, and a land development agreement or site-specific plan may also be required.12 Colorado law allows county zoning in unincorporated territory to regulate uses, building location and size, lot size, coverage, open space and density, but that statewide authority does not supply the parcel's actual limits.13 Numeric setbacks, minimum dwelling size, minimum lot size, height and lot coverage could not be confirmed; ask the Commissioners for the standards tied to the parcel and proposed use.

How do septic permits work in Dolores County?

A new or altered onsite wastewater treatment system in Dolores County requires a county permit process that includes an application, site plan, soils evaluation, professional design, approval, final inspection and final permit.4 The new-system permit fee is $400, including the $23 state surcharge, and a repair or alteration permit costs $300.4 Construction must remain uncovered until the Dolores County Board of Health Inspector performs the required final inspection.5 Only 7.8% of mapped county soils avoid a severe conventional drain-field limitation, so make the site and soil evaluation an early feasibility step rather than assuming a standard field will work.14 Colorado also prohibits new cesspools and requires adequate sanitary sewage disposal for occupied structures not served by a sewage treatment works.15

Can you live in an RV or tiny home in Dolores County?

Dolores County's rule for residential or long-term RV occupancy on private land could not be confirmed, so ask the Board of County Commissioners before using an RV as a dwelling or while building. The state rule for camping in state parks does not answer what is allowed on private property.16 A Colorado-regulated tiny home intended for long-term residential occupancy requires state plan approval before construction, compliance with applicable state codes and standards, and compliance with local zoning.6 Dolores County has land-use regulations, so a small footprint alone does not bypass local review.3 The county's minimum dwelling size and tiny-home occupancy standards could not be confirmed; take the unit plans, foundation type, wastewater plan and parcel information to the Commissioners before purchase or placement.

Building a home in Dolores County: what are the steps?

  1. Ask the Board of County Commissioners to identify the land-use, subdivision, floodplain and development approvals for the parcel.2
  1. Confirm with the county whether the specific home needs any construction approval despite Dolores County being identified as not requiring a general building permit.1
  1. File the required Improvement Notice with the Assessor's Office before construction.11
  1. Apply for the OWTS permit, complete the soils evaluation and engineering, and obtain design approval before installing septic.4
  1. Secure a county-road driveway permit through county addressing, or a state access permit if the house connects directly to a Colorado state highway.1718
  1. Leave the OWTS uncovered for final inspection and obtain the final septic permit before use.5

What should you check before buying land in Dolores County?

Check wastewater feasibility first: only 7.8% of mapped soils avoid severe limits for a conventional septic drain field.14 Confirm legal and practical access; a county-road driveway requires a county permit, while direct house access to a state highway requires a Colorado access permit.1718 Check the flood map because development in a mapped special flood-hazard area of unincorporated Dolores County requires a permit.8 A new groundwater well generally needs a permit from the Colorado Division of Water Resources, subject to exemptions and basin-specific rules.7 The county's effective property-tax rate is about 0.2%, with a median annual bill of $558, but verify the actual parcel assessment and taxing districts with the Assessor.1920

Watch-outs

  • No county building department does not mean no paperwork: the Assessor requires an Improvement Notice before construction.111
  • Do not backfill a new or altered septic system before the required final inspection.5
  • Development in a mapped special flood-hazard area of unincorporated Dolores County requires a floodplain permit.8
  • RV occupancy, minimum dwelling size and numeric setbacks could not be confirmed; ask the Board of County Commissioners before relying on a seller's description.10
