Registration details
  • license: LaSalle Municipal Code Chapter 6 (Business Licenses and Regulations), Article II (Licenses), was read in full via the Municode API. Sec. 6-26 "General business license" requires "every person" to obtain an annual business license "before operating, conducting or carrying on any trade, profession or business... within the town" -- a general municipal license applying equally to any business, not a contractor-specific credential (no trade classes, ICC certification, or contractor-specific insurance requirement). Chapter 6's other articles license only Alcoholic Beverages, Amusement Devices, Burglar Alarms and Junkyards/Junk Dealers. Chapter 18 (Building Regulations), covering Articles I-XVI (the adopted International Building, Electrical, Plumbing, Mechanical, Residential, Energy, Fire, Fuel Gas, Property Maintenance, Existing Building, Swimming Pool/Spa, Electric/Solar Ready and Wildfire Resiliency Codes, plus Graywater Systems), was also read in full and contains no contractor licensing article.
Permit process note
"Roofs" are listed among the projects requiring a building permit. Building permit applications and plan review are processed by Town of LaSalle staff, and inspections are performed under contract by ProCode, Inc. (970-305-3161). Contractors and residents may also apply for permits and request inspections electronically through the town's Community Core online portal.
Adopted code
The Town of LaSalle has adopted and is currently enforcing the 2018 International Codes, the 2012 International Energy Conservation Code, and the 2020 National Electrical Code.
Drip edge
Required — Not separately amended by the Town of LaSalle. Municode Sec. 18-147, the full 2024 IRC amendments list (32 numbered items, R101.1 through P3103.1.1), was read in its entirety and does not delete or modify R905.2.8.5, so the base 2024 IRC drip-edge requirement stands as adopted code. About drip edge
Ice & water shield
Required — LaSalle Municipal Code Sec. 18-147(16)'s Table R301.2(1) amendment prints "Ice Barrier Underlayment Required" as "Yes" alongside the town's other climatic design values. About ice & water barrier
Impact-resistant roofing
Required — LaSalle Municipal Code Sec. 18-147(25): "IRC Section R905.2.4 (Impact resistance of asphalt shingles) is amended with the addition of the following after the first sentence: Asphalt shingles shall be Class 4 impact resistant, tested in accordance with UL2218, and installed in accordance with the manufacturer's installation instructions," subject to two exceptions permitting non-Class-4 replacement/repair shingles when matching an existing color or style for which Class 4 options are unavailable.
Repair permit threshold
LaSalle Municipal Code Sec. 18-147(4)(b) (Amendments to the International Residential Code, 2024 Edition, adopted by Ord. No. 19-2025, Section 9, 12-9-2025): "IRC Section R105.2 (Work Exempt from Permit) is amended by:... Building Exception #10 is deleted in its entirety and replaced with: 'Shingle repair or replacement work not exceeding one square (100 square feet in area) of covering per building.'" Shingle repair/replacement at or above 100 square feet therefore requires a building permit.
Wind design criteria
LaSalle Municipal Code Sec. 18-147(16) (Amendments to the 2024 IRC, Ord. No. 19-2025, Section 9, 12-9-2025): "IRC Table R301.2(1) is filled to provide the following: Table R301.2(1) Climatic and Geographic Design Criteria" -- Ground Snow Load "30 psf"; Wind Design Speed (V) "115"; Topographic Effects "No"; Seismic Design Category "B"; Weathering "Severe"; Frost Line "30 in."; Termite "Slight to moderate"; Winter Design Temp. "1" degrees F.; Flood Hazard "Map #s 08123C1726F 08123C1727F 08123C1730F 11/30/2023"; Air Freezing Index "1,000"; Mean Annual Temp. "43 F."
Sales & use tax
6.4% combined (state 2.9% + Weld County 0% + Town of LaSalle 3.5%; no RTD/SCFD/RTA district). Weld County levies no county-wide sales tax (see the weld-county record). Per CO DOR DR 1002's "State-Collected City Sales Taxes" table, LaSalle's row reads "Weld / 3.50% / 3.33% [service fee] / [no exemption] / 2% [use tax] / Motor Vehicles, Building Materials" (state-collected, not self-collecting home-rule). The DR 1002 use-tax figure (2%) matches the Town's own Building Permits page, which states a "2% use tax on the total cost of the material" is charged on building permits, corroborating that this DR 1002 row has not gone stale for LaSalle. 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.
