La Salle, Colorado has adopted: 2018 International Building Code (IBC) — per the Town of La Salle Building Permits page: 'The Town of LaSalle has adopted and is currently enforcing the 2018 International Codes, 2012 Energy Conservation Code, and 2020 National Electrical Code.'; 2018 International Residential Code (IRC); 2018 International Mechanical Code (IMC); 2018 International Plumbing Code (IPC); 2018 International Fuel Gas Code (IFGC) (bundled under the page's 'International Codes' reference; not itemized by individual code title on the live page); 2012 International Energy Conservation Code (IECC) — the live page names this specifically as '2012 Energy Conservation Code,' an older cycle than the 2018 base I-Codes it is paired with; 2020 National Electrical Code (NEC); 2025 Colorado Wildfire Resiliency Code (Colorado Division of Fire Prevention and Control model code, dfpc.colorado.gov/WRCB) — listed as adopted on the Town's Building Permits page; Model Colorado Electric and Solar Ready Code (Colorado Energy Office, energyoffice.colorado.gov/building-energy-codes-toolkit) — listed as adopted on the Town's Building Permits page; Note on document currency and code-cycle discrepancy: the Town's Municode-codified Chapter 18 (Building Regulations), as of this review, still recites the 2003 IBC/IRC/IPC/IMC/IFGC, 1999 NEC, and 1997 Uniform Code for Abatement of Dangerous Buildings, with a 1977/1978-vintage Colorado energy standard — none of which match the 2018 I-Codes / 2012 IECC / 2020 NEC the Town's actively-maintained Building Permits webpage states it is 'currently enforcing.' Consistent with this corpus's established pattern (e.g. Vail), the live, actively-maintained Building Permits page is treated as the current governing statement of adopted codes, since Municode codification frequently lags the underlying adopting ordinances and La Salle's own current-enforcement statement is unambiguous and specific (exact code years named). The codified Chapter 18 text is retained here only as a source of durable local AMENDMENT language (definitions, frost depth, sleeping-room rules, refund provisions, fee-authorization mechanism) that is very likely still in force, since local amendments of this kind are typically carried forward from cycle to cycle rather than dropped, but the umbrella code EDITIONS themselves follow the live page.; Note on HB22-1362 (statewide energy floor, window July 2023-July 2026): the Town's stated 2012 IECC base energy code edition does NOT itself meet HB22-1362's requirement that jurisdictions updating their code during this window adopt at least the 2021 IECC. However, the Town's Building Permits page separately lists the 'Model Colorado Electric and Solar Ready Code' as adopted alongside the 2025 Colorado Wildfire Resiliency Code — meaning La Salle appears to have layered on the HB22-1362 electric/solar-ready provisions as a standalone addition without upgrading its underlying energy-code base edition to 2021 IECC. This is reported honestly as observed; this file does not assume full HB22-1362 compliance, only that the electric/solar-ready model code specifically has been adopted per the Town's own published list.; MAJOR RE-CHASE UPDATE, 2026-07-23 — Municode reversal: this file's prior methodology (see the two notes above) treated the Town's Municode-hosted codification as a stale 2003-era snapshot and deferred to the live Building Permits webpage for current code editions. A direct re-chase of library.municode.com/co/lasalle on 2026-07-23 found this assumption is NO LONGER CORRECT: La Salle's Municode codification is now current through Ordinance No. 5-2026 (enacted 3-24-2026), online content updated 7-1-2026, and Chapter 18 was comprehensively overhauled by Ordinance No. 19-2025 (adopted 12-9-2025) — confirmed by reading each article's adoption section directly: Sec. 18-18 now adopts the 2024 IBC (not 2018), Sec. 18-43 the 2023 NEC (not 2020), Sec. 18-68 the 2024 IPC (not 2018), Sec. 18-93 the 2024 IMC (not 2018), Sec. 18-143 the 2024 IRC (not 2018), and Sec. 18-166 the 2024 IECC (not 2012 — which would also resolve the HB22-1362 gap flagged in the note above, since 2024 IECC exceeds the 2021 IECC statewide floor). Chapter 18 was also restructured into 16 articles, adding new Article IX (2024 International Fire Code), Article XI (International Property Maintenance Code), Article XII (International Existing Building Code), Article XIII (International Swimming Pool and Spa Code), and Article XVI (Graywater Systems) — none of which are reflected in the Town's own Building Permits webpage, which as of this same re-chase (2026-07-23) still states only '2018 International Codes, 2012 Energy Conservation Code, and 2020 National Electrical Code.' The two Town-controlled channels now directly conflict, and the codified ordinance (more recently dated, and the Town's actual governing law) appears to be the accurate one, while the informational webpage appears to be the stale one — the reverse of this file's original assumption. Local-amendment LANGUAGE spot-checked against the new codification (120 sq ft accessory-structure exemption, 180-day permit expiration/half-fee renewal, 80% refund provisions, sleeping-room definition) was found carried forward unchanged into the 2024-edition articles, so those specific amendment provisions remain reliable. However, a full re-verification of every permitType's code-edition citations, and of the five newly-added articles, was OUT OF SCOPE for this partial-chase pass (which targeted only fee/timeline gaps) and should be treated as a distinct, dedicated follow-up chase rather than assumed complete.

Yes. The Town's Building Permits page explicitly lists basement refinishes among the project types requiring a permit.
