The Building Department page states the town "contracts with an independent company, called SAFEbuilt, to help with new construction, remodeling and development projects for both Residential and Commercial work," with applications and plans "processed through CommunityCore which is an online permitting system" (paper/PDF applications remain available; contractors request a CommunityCore company login from the Building Permits Technician). Municipal Code Sec. 18.02.010: "No structure shall be erected, moved or structurally altered without a building permit issued by the Building Official or other authorized persons." A roofing permit is required on the strength of that general permit-requirement language together with Chapter 18's adoption of the 2021 IBC/IRC (which regulate roof replacement); no roofing-specific town handout was found. The town also offers free Design Review Committee (DRC) meetings for project planning. Chief Building Official: Alejandro Pantoja (SAFEbuilt), 720-582-9850.

Municipal Code Sec. 18.04.010: "The International Building Code, 2021 Edition ... is adopted by reference" (adopted in full including appendices AI and AN only; Ord. 2024-07-15A). Sec. 18.13.010: "The International Residential Code, 2021 Edition ... is hereby adopted," applying "to the construction of, and renovations or additions to, all commercial and residential buildings within the Town." Chapter 18 also carries separate articles adopting energy, fire, electrical, mechanical, plumbing, fuel gas, existing-building, and swimming-pool codes. Code current through Ordinance 2026-04-20B (passed May 18, 2026).

Not required — The Town of Mountain View's codified Municipal Code, Chapter 18, Building Regulations, was read in full across its building, residential, existing-building, fire and permit articles. Section 18.04.010 adopts the 2021 International Building Code in full with Appendices AI and AN, Section 18.13.010 adopts the 2021 International Residential Code in full, and Section 18.12.010 adopts the 2021 International Existing Building Code in full with Appendix B, each by Ordinance 2024-07-15A of July 15, 2024, with later amendments by Ordinances 2024-11-18B and 2024-12-16A. Each article carries its own enumerated amendment list, read in full: sixteen to the Building Code, six to the Residential Code and two to the Existing Building Code, addressing permit exemptions and posting, surveyed site plans, stop-work orders, smoke and carbon monoxide alarms, flood hazard mapping, frost depth and excavation barriers, together with the deletion of the residential sprinkler section and a requirement that penthouse walls and roof construction carry the fire-resistance rating of the building's construction type. No amendment touches Chapter 9 of the Residential Code or the roof-covering sections of Chapter 15 of the Building Code. The 2021 International Fire Code is adopted at Section 18.05.010 as amended by the West Metro Fire Protection District; that is a fire code and is independent of impact rating. Neither the adopted codes nor any Town amendment requires impact-resistant roof coverings or names a UL 2218 or Class 4 standard. The only statewide instrument reaching reroofing is the Colorado Wildfire Resiliency Code, 8 CCR 1507-39, effective July 1, 2026 in areas designated wildland-urban interface under that code, which requires a Class A roof covering tested to ASTM E108 or UL 790 where 25 percent or more of the roof surface is replaced, at Sections 101.6 and 403.2; that is a fire classification independent of impact rating, and the code sets no impact-resistance requirement.

8.5 percent combined: 2.9 percent state, 0.50 percent Jefferson County, 1.0 percent Regional Transportation District, 0.1 percent Scientific and Cultural Facilities District, and 4 percent Town of Mountain View. The Town is state-collected. The Colorado Department of Revenue publication DR 1002 prints the Town at 4 percent with no service fee, and places all of Jefferson County inside both district boundaries without any carve-out -- the transportation district covers the "Counties of Denver, Boulder, and Jefferson" and the cultural district covers "All areas within the county boundaries of Adams, Arapahoe, Boulder, Jefferson, Denver and Broomfield." Separately, the Town collects a construction-materials use tax at building-permit issuance, calculated on 50 percent of the declared valuation. Two of the current Town documents state that use-tax rate differently. The Use Tax Calculation and Valuation Election form, which a contractor completes with the permit application, sets it at 3 percent, matching the use-tax figure DR 1002 prints for the Town; the Building Department frequently-asked-questions page instead describes the calculation as valuation times 50 percent times 4 percent, which is the general sales tax rate for the Town.
