Larkspur, Colorado has adopted: Town of Larkspur Ordinance 2022-11, Adopting Building Codes — the Town's Building Codes page (townoflarkspur.org/building-department/page/building-codes) names this ordinance as the governing building-code adoption instrument, alongside a companion document titled 'Building Codes at a Glance.'; CLOSED 2026-07-23 — Code-edition specificity, on a LIVE primary source: the SharePoint-hosted ordinance PDF remains behind a confirmed Microsoft OAuth authentication wall (re-tested 2026-07-23: all six 'Building Codes' page SharePoint share links, plus a seventh on the Fee Schedules page, still redirect straight to login.microsoftonline.com with no anonymous-view path — genuine, re-confirmed barrier). However, a NEW avenue closed the gap on a different live channel: Municode's hosted Larkspur Municipal Code (library.municode.com/co/larkspur), which the prior pass could not load (401/403 via curl against its Angular API), loads successfully in a real browser session and is the Town's official codified code, current through Supplement 15 (online content updated April 6, 2026). Chapter 18 — Building Regulations, Articles 1 through 11, all cite 'Ord. No. 2022-11' as their sole adopting/amending ordinance with no later amending ordinance for any article except Article 4 (Fire Code, also amended by Ord. No. 2023-01, § 1, 2-16-2023). The codified text gives the exact adopted edition for every code family: International Building Code (Art. 1) — 2018 Edition, Ch. 1-35 + Appendix Chapters E, I, N; International Plumbing Code (Art. 2) — 2018 Edition, Ch. 1-13, Ch. 15, Appendix Chapters C, E; International Mechanical Code (Art. 3) — 2018 Edition, Ch. 1-15 + Appendix Chapter A; International Fire Code (Art. 4) — 2018 Edition, Ch. 1-80 + Appendix B-N; International Fuel Gas Code (Art. 5) — 2018 Edition, Ch. 1-8 + Appendix Chapters A-D; International Residential Code (Art. 6) — 2018 Edition, Ch. 1-44 + Appendix Chapters A, E, G, H, J; International Energy Conservation Code (Art. 7) — 2018 Edition, Ch. 1-6 + Appendix RA (IRC Ch. 11 Energy Efficiency is separately deleted and replaced with the 2018 IECC per IRC amendment #28); International Property Maintenance Code (Art. 8) — 2018 Edition, Ch. 1-8 + Appendix A; National Electrical Code (Art. 9) — 2020 Edition (adopted per Title 31, Article 16, Part 2, C.R.S., 'as adopted, amended and updated to the most current edition by the Colorado State Electrical Board from time to time' — i.e. tracks DORA/State Electrical Board updates, consistent with this file's electrical-permit deferral finding); International Existing Building Code (Art. 10) — 2018 Edition, Ch. 1-16; International Swimming Pool and Spa Code (Art. 11) — 2018 Edition, Ch. 1-11.

Cross-verified against the Town's own Town Council Meeting Minutes of 4-21-2022 (media ID 2246, hosted directly on townoflarkspur.org, not SharePoint): 'Councilmember Mindy Kazurova made a motion to approve Ord..2022-11 an Ord. adopting by reference of the International Building Codes 2018 editions... Roll call vote Six (6) approved, zero (0) opposed, Mayor affirmed Motion Passed.'; Colorado is a home-rule state with no single statewide-mandated building code edition for municipalities generally; Larkspur, as a home-rule town, sets its own adopted code editions by ordinance (Ordinance 2022-11, 4-21-2022) rather than following a state-mandated cycle.; CLOSED 2026-07-23 — HB22-1362 (statewide energy code floor) applicability, on LIVE sources: HB22-1362 does not impose a flat statewide deadline; per its own trigger mechanism (confirmed via Colorado Energy Office / AIA Colorado / Southwest Energy Efficiency Project reporting), a jurisdiction is only required to adopt the 2021 IECC (or an equivalent/better code) when it next updates ANY of its other building codes, with a one-year transition window, and again by 7-1-2026 under the state's Model Low Energy and Carbon Code. Larkspur's only building-code action since HB22-1362's 2022 enactment is Ordinance 2022-11 itself (4-21-2022), which predates the bill and was not a post-enactment update; the live Municode codification (Supplement 15, current through 4-6-2026) shows no ordinance amending Chapter 18 Article 7 (Energy Code) or any other Article after Ord. 2022-11 (except the unrelated Fire Code amendment, Ord. 2023-01). Because Larkspur has not updated any of its building codes since HB22-1362 took effect, its 2021-IECC trigger has not yet activated, and the Town's 2018 IECC (adopted via Ord. 2022-11) remains its lawfully current energy code as of this research date. Source: https://library.municode.com/co/larkspur/codes/municipal_code?nodeId=CH18BURE_ART7INENCOCO (live).; Electrical permits: Larkspur's own website hosts a PDF titled 'Electrical Permit Fees' at https://www.townoflarkspur.org/media/2901 which, on direct inspection, is the Colorado Department of Regulatory Agencies (DORA) / Division of Professions and Occupations statewide Electrical Permit Fee Schedule (effective April 1, 2016; document letterhead address 1560 Broadway, Suite 1350, Denver, CO 80202, phone 303-894-2300, www.dora.state.co.us) — i.e. Larkspur does not run its own local electrical permitting program or set its own electrical fee schedule; it defaults to the Colorado State Electrical Board (DORA/DPO) fee structure per CRS 12-23-117(3), consistent with this project's Colorado-specific default rule. Larkspur is documenting/republishing the state's fee form rather than issuing an independent municipal fee schedule. CONFIRMED 2026-07-23 on the live Municode codification: Larkspur Municipal Code Sec. 18-9-10 formally adopts the National Electrical Code, 2020 Edition, 'as adopted, amended and updated to the most current edition by the Colorado State Electrical Board from time to time' — the code text itself directs to the state board's current edition rather than fixing a static local edition, matching the DORA-deferral finding above.; Plumbing permits: no evidence was found of a Larkspur-specific plumbing permit fee schedule or a locally-administered plumbing licensing/inspection program distinct from the general SAFEbuilt-administered Building Permit process; plumbing permit review appears to be folded into SAFEbuilt's general building-permit review (the 'PLUMBING ONLY' permit type appears on the Town's own permit-type list, issued through the same SAFEbuilt/CommunityCore process as other trade permits, not a standalone state-board deferral the way electrical is). Documented honestly as SAFEbuilt-administered under the general building permit umbrella rather than assumed to default to the Colorado State Plumbing Board absent direct confirmation of that specific deferral. PARTIALLY CLOSED 2026-07-23: the live Municode codification confirms this — Larkspur Municipal Code Sec. 18-2-10 adopts the International Plumbing Code, 2018 Edition, and Sec. 18-2-40(2) (IPC § [A]106.6.2, Fee schedule) is locally amended to read 'The fees for work shall be as indicated on the Town's Fee Schedule adopted by the Town Council,' cross-referencing Appendix A—Fee Schedule, which in turn lists Sec. 18-2-40 at a flat $30.00 Town administrative fee 'plus fees outlined in Exhibit C "Town of Larkspur Fee Table" in the professional service agreement between the Town of Larkspur and Safebuilt Colorado.' This explains, on a live authoritative source, why no itemized plumbing valuation-based fee table is published anywhere on the Town's own site: the actual dollar-amount schedule is Exhibit C of a private Town-SAFEbuilt services contract, not a document the Town routinely publishes — a structurally different (and confirmed-genuine) reason than the earlier SharePoint access-wall hypothesis, not merely an unresolved access barrier. The $30.00 base administrative fee is now a verified, live-sourced figure; the underlying SAFEbuilt Exhibit C valuation table remains unrecoverable through any public channel located in this pass.
