Registration details
  • license: The Pull a Building Permit page states: "All contractors must register with CommunityCore AND be listed on the Building Permit before it will be issued." This is a permit-portal registration requirement rather than a City business license: per the City Clerk's Business/Sales Tax Licensing page, Ordinance 2023-3 (under SB22-032) limits Business/Sales Tax Licenses to brick-and-mortar businesses operating within the City only, and "NO OTHER BUSINESS is required to apply or renew their license."
Permit process note
The "Do I Need a Permit?" page lists, under both "Commercial Permits Required" and "Residential Permit Required": "Any re-roofing project or any roof repair that requires more than 25% of the roof to be replaced"; the residential list also separately includes "Re-roofing" alongside siding, room additions, and solar panels. "A building permit must be pulled through our online permit portal, CommunityCore, serviced through the city's Building Division, which is contracted through SAFEbuilt." Stated SAFEbuilt plan-review timeframes: residential 5 business days, minor projects (valuation under $2M) 10 business days, major projects ($2M or more) 20 business days. All permit drawings must be collated into a single Bluebeam-ready submittal, Black Hawk Fire Department review is required, and all fees are due at permit issuance (payable by card, check, or cash through CommunityCore).
Adopted code
The Adopted Codes and Design Criteria page states the City has adopted the 2021 I-Codes: the International Building, Fire, Residential, Mechanical, Plumbing, Energy Conservation, Existing Building, Fuel Gas, Property Maintenance, and Swimming Pool and Hot Tub Codes, all 2021 Edition (several with certain appendices), plus the 1997 Uniform Code for the Abatement of Dangerous Buildings, the most current state-adopted NEC (effective in Black Hawk one year after state adoption), and the "Wildfire Resiliency Code, 2025 Edition - Adopted April 1, 2026 - Effective July 1, 2026." Design criteria include a 77 psf commercial snow load, wind speeds per the Colorado Front Range Gust Map (2021 IBC 1609.3), and a 48-inch frost depth. Note: the City's separate "Do I Need a Permit?" page still states "The City of Black Hawk is currently under the 2015 Adopted I-Codes" - an internal inconsistency with the Adopted Codes page's 2021 listing.
Drip edge
Required — Not separately amended by the City of Black Hawk. § 18-6 (Amendments to International Residential Code, 2021 Edition, 12 numbered items, R101.1 through P2603.5.1, read in full and exhaustive) does not delete or modify R905.2.8.5, so the base 2021 IRC drip-edge requirement stands as adopted code. About drip edge
Ice & water shield
Required — Black Hawk Municipal Code § 18-6 item (9), Table R301.2(1) as amended: "Ice Barrier Underlayment Required: Yes." About ice & water barrier
Impact-resistant roofing
Not required — No City of Black Hawk amendment mandates Class 4 / UL 2218 impact-resistant roof coverings. All ten Article I code-amendment sections (Building, Fire, Residential, Mechanical, Plumbing, Energy, Existing Building, Fuel Gas, Swimming Pool/Spa, and Property Maintenance Code, §§ 18-4 through 18-13) were read and contain no UL 2218 or Class 4 reference anywhere.
Wind design criteria
Black Hawk Municipal Code § 18-6 item (9) amends Table R301.2(1) Climatic and Geographic Design Criteria: Ground Snow Load "55 psf"; Wind Design Speed "130 mph 3 Sec Gust"; Wind-Borne Debris Zone "No"; Seismic Design Category "B"; Weathering "Severe"; Frost Depth "48 inches"; Termite "Slight-Moderate"; Winter Design Temp "0°"; Flood Hazards "See Footnote G" (citing the FEMA Flood Insurance Study for Gilpin County, dated April 6, 2022); Air Freezing Index "2000"; Mean Annual Temp "45°." A "Table R301.2(1) - continued" block immediately follows with Roof Snow Load "38 psf," Wind Speed restated as "130 3 Sec Gust," Climate Zone "7."
Sales & use tax
6% City of Black Hawk sales tax (per DR1002's Home Rule Cities table, corroborated independently by Gilpin County's own Sales Tax Information page: "Black Hawk: 6.00%"), plus state 2.9% (Gilpin County itself levies no county sales tax — see gilpin-county entry) = 8.9% combined within Black Hawk city limits. Black Hawk is home-rule, self-collected (listed in DR1002's "Home Rule Cities For Which The State Does Not Collect Local Sales Tax" table). DR1002's own layout also carries a second "6%" marked with footnote 6 ("Use tax") on the same city row, indicating Black Hawk imposes its own 6% use tax as well, though this is not independently corroborated on a published City page. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
