Do you need a permit to replace a roof in Dillon, CO?

Town of Dillon, Colorado

city

275 Lake Dillon Drive, Dillon, CO

Most development and construction within Dillon town limits requires a Town of Dillon Development Permit and, in most circumstances, a companion Summit County Building Permit and/or a Grading and Excavation Permit. The town states that a Development Permit application and issuance are required prior to submitting to Summit County for the Building Permit; Summit County has its own separate application process and fee schedule. Rooftop solar has its own town permit path. Roofing is not called out as its own town permit type; the building-permit side of a reroof runs through Summit County.

Not required — The Town of Dillon does not maintain its own building code; it adopts the Summit County Building Code, and Dillon Municipal Code Chapter 18 carries only the Town's local modifications to it. Chapter 18 was reviewed in full and its modifications are confined to administrative and energy provisions, with no roofing amendment of any kind. The Summit County instrument itself, Summit County Resolution No. 2026-45, Exhibit A, adopting the 2024 I-Code series effective for plans submitted on or after July 1, 2026, contains no impact resistance or UL 2218 Class 4 provision. Neither half of the pair requires an impact rating.
