Photovoltaic (Solar) Permit in Dillon, Colorado

Required for residential and commercial photovoltaic (solar) system installations in Dillon. A Town of Dillon Development Permit is required first (solar panels are explicitly listed among projects requiring a Development Permit). The Summit County Building Inspection Department then issues the PV permit; residential roof-mounted systems under 15kW may be issued over the counter if the submittal is complete, while larger, ground-mounted, and commercial systems require plan review.

Tips

  • A residential roof-mounted system under 15kW with a fully complete submittal can potentially be issued over the counter — have every required document (application, submittal requirements, checklist) ready to maximize the chance of same-visit issuance.
  • Ground-mounted systems always require plan review regardless of system size.

Dillon, Colorado has adopted: 2024 International Building Code (IBC) series with local amendments — Summit County Building Inspection Department completed adoption of the 2024 I-Code series; per the department's live announcement (checked 2026-07-06), all plans submitted on or after July 1, 2026 must comply with the 2024 I-Codes; 2024 International Residential Code (IRC) with local amendments — part of the same 2024 I-Code series adoption; 2024 International Energy Conservation Code (IECC) with amendments — replaces the former 'Summit County Sustainable Code' option for single-family homes; the Sustainable Code is no longer an energy-compliance pathway as of this adoption, per the department's own announcement; Appendix REMP (Renewable Energy Mitigation Program) — added with the 2024 code adoption, per Summit County Building Inspection Department announcement; Appendix BC (Accessory Dwelling Units for existing construction) — added with the 2024 code adoption, per Summit County Building Inspection Department announcement; Colorado Wildfire Resiliency Code — any permit applied for on or after May 4, 2026 is subject to the newly adopted fire codes, including the updated sprinkler square-footage threshold; the full code is published by the Colorado Division of Fire Prevention & Control (dfpc.colorado.gov/colorado-wildfire-resiliency-code); Sprinkler requirement: all new residential structures 4,500 sq ft or greater must have fire sprinkler systems installed, per the Colorado Wildfire Resiliency Code as adopted by Summit County; Town of Dillon Municipal Code, Chapter 18 — the Town has, 'in conjunction with Summit County... in general adopted the 2018 series of Building Codes with amendments' at the town-code level; however, the Summit County Building Inspection Department (which actually performs plan review/inspection for Dillon) has since moved forward to the 2024 I-Code series described above — this is a genuine, honestly-flagged discrepancy between the Dillon Municipal Code's own text (last referencing 2018) and the county department's current live practice (2024, effective July 1, 2026); applicants should confirm the currently-enforced edition directly with Summit County Building Inspection at time of submittal.
