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

Yes. Eagle County requires a building permit to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure anywhere in the unincorporated county1. Colorado law allows counties to adopt building codes and require permits outside incorporated cities and towns, with a possible exception for structures used solely to shelter agricultural implements, farm products, livestock or poultry10. Owner-builders and general contractors do not need registration or a license to build in unincorporated Eagle County, but plumbers and electricians need active Colorado credentials, architects and engineers must be Colorado-licensed, and septic installers need an Eagle County license4. Before drafting plans, call the Planner On Duty to identify parcel-specific limits such as floor area ratio, lot coverage, height, and ridgeline or stream setbacks6.

Who is the Eagle County building department, and how do you reach them?

The Eagle County Building Division reviews plans and performs inspections for unincorporated Eagle County construction, and the office is open Monday through Friday, 8 a.m. to 5 p.m.11. Call 970-328-8761, or mail correspondence to 500 Broadway, Eagle, CO 8163111. The county publishes building permit fees by project valuation; each application also carries a plan-review charge equal to 65% of the permit fee, and a reinspection costs $10012. Before designing, call 970-328-8746 and ask for the Planner On Duty to verify zoning and parcel constraints6. Floodplain development, road cuts, grading and county-road access permits go through Engineering at 970-328-3560 or [email protected]13. These county contacts and fees apply to unincorporated land, not projects governed by a town.

Does Eagle County have zoning?

Yes. Eagle County administers its own Land Use Regulations governing zoning and land use in unincorporated areas2. Regulatory control over land use planning goes back to 1964, when the county commissioners adopted procedures to subdivide property in unincorporated areas, and zoning regulations followed in the mid-1970s6. Colorado law backs this local authority broadly: a county zoning plan can regulate building location, height, bulk, lot coverage, lot size, open space and density across unincorporated territory14. A HUD-code manufactured home can be installed anywhere in Colorado only where local zoning allows it, so confirm your parcel's zoning district before you plan around one15. Colorado's 2024 accessory dwelling unit law requires certain jurisdictions to allow at least one ADU by administrative approval starting June 30, 2025, but the law does not make every Colorado county area a covered jurisdiction, so ask Eagle County Planning whether your parcel qualifies16.

How do septic (OWTS) permits work in Eagle County?

Eagle County Environmental Health administers OWTS permits and contractor licensing, while Colorado Regulation 43 supplies statewide minimum standards for systems with flows of 2,000 gallons per day or less3. A county permit is required for every new OWTS installation, alteration or repair17. Every Eagle County OWTS must be designed by a Colorado Registered Professional Engineer and installed by an Eagle County-licensed installer; installers and cleaners also need a System Contractor license from Environmental Health17. Reach the department at 970-328-8755 or [email protected]18. State law requires an OWTS permit before construction, alteration, installation, repair or use where a building lacks sewer service, followed by final inspection before use1920. Only about 4.1% of Eagle County soils are rated without severe limits for a conventional drain field, reinforcing the need to price site evaluation and engineered design early21.

Can you live in an RV or tiny home on your land in Eagle County?

This guide could not confirm a county-specific rule allowing or barring RV living on a private rural parcel in unincorporated Eagle County; call the Planning line at 970-328-8746 and ask for the Planner On Duty before you plan around one for a specific parcel6. Don't rely on Colorado's state-park camping rules to answer this: those cover land Colorado Parks and Wildlife controls, not private land22. A tiny home has a clearer statewide path if it's built to Colorado Division of Housing standards: plans must be submitted to and approved by the Division before construction, the unit must meet Colorado-adopted codes, and it's certified for the specific site where it's installed23. A certified HUD-code manufactured home follows the same local-zoning gate as any home: it can go anywhere in Colorado only where local zoning allows it, which is why Eagle County's own building permit already covers manufactured and modular home placement151.

Building a home in Eagle County: the steps, in order

  1. Call 970-328-8746 and ask for the Planner On Duty to confirm your parcel's zoning district and constraints (floor area ratio, lot coverage, height, ridgeline and stream setbacks) before you design6.
  2. Check your access and floodplain status with the Engineering Department, since road cut, grading and access permits, plus floodplain development review, run through that office rather than Building13.
  3. Apply for a well permit through the Colorado Division of Water Resources if you're not on a water system; a complete application can take up to 49 days to review7.
  4. Apply for an OWTS (septic) permit with Eagle County Environmental Health if you're not on sewer; the system must be designed by a Colorado Registered Professional Engineer and installed by an Eagle County-licensed OWTS Installer17.
  5. Submit your building permit application to the Building Division at 500 Broadway in Eagle, or by mail, and design to the county's published structural criteria, including a winter design temperature of -20°F, a 48-inch frost depth, and ice-barrier underlayment required within 3 feet of eaves and valleys611.
  6. Build to your issued permit and schedule inspections with the Building Division, which reviews plans and inspects unincorporated-county construction11.

What to check before you buy land in Eagle County

Confirm which jurisdiction actually governs the parcel: Avon, Basalt, Eagle, Gypsum, Minturn, Red Cliff and Vail each have their own building departments and rules, and this guide's county-level answers apply only outside those town limits. Septic soils are a real constraint countywide, with only about 4.1% of Eagle County's soils rated free of severe limits for a conventional drain field, so budget for a site evaluation and likely an engineered OWTS21. If the parcel isn't on a water system, a new well needs its own permit from the Colorado Division of Water Resources, and review of a complete application can take up to 49 days7. Watch the OWTS regulation timeline: Eagle County updated its septic rules in March 2026, and a new OWTS Adequacy Review Permit with Transfer of Title inspections takes effect January 1, 2027, which can affect what a seller needs to have inspected before closing17. Federal land dominates this county, at about 79.3% of its area, which limits how much private rural land exists and can affect access and views near a parcel24. Property taxes run moderate for a high-value mountain county: Eagle County's effective rate is about 0.4%, with a typical annual bill near $3,33989. The county sits roughly 80 miles from the nearest city of 100,000 or more people, so plan on that drive for big-box shopping, a major airport or a hospital beyond what the Vail Valley itself offers25.

Watch-outs

  • Eagle County updated its OWTS (septic) regulations on March 6, 2026, and will add an OWTS Adequacy Review Permit requirement, including Transfer of Title inspections, on January 1, 2027; confirm current requirements with Environmental Health rather than an older summary17.
  • Avon, Basalt, Eagle, Gypsum, Minturn, Red Cliff and Vail each administer their own building and zoning rules inside town limits; this guide's answers apply only to unincorporated Eagle County6.
  • This guide could not confirm a specific county rule on living in an RV on a private rural parcel; call Eagle County Planning at 970-328-8746 and ask for the Planner On Duty before you count on one6.

    • After adoption of the building code, construction, reconstruction, alteration, or remodeling in the designated area requires a building permit, except for the agricultural-shelter exception.
    • The board must fix a reasonable schedule of building-permit fees; no permit fee may be charged unless a qualified inspector actually performs an inspection.
    • Plans must conform to the building code, and plans and specifications generally must bear the seal of a Colorado-licensed architect or engineer unless exempted by section 12-120-403.
    • Every county adopting or updating a building code must adopt and enforce an energy code meeting or exceeding one of the three most recent International Energy Conservation Code versions under section 30-28-211.
