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.'; The Town's ordinance PDFs are hosted on SharePoint behind a Microsoft login — all six 'Building Codes' page share links, plus a seventh on the Fee Schedules page, redirect to login.microsoftonline.com with no anonymous-view path. Use Municode's hosted Larkspur Municipal Code instead: it 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. it tracks DORA/State Electrical Board updates, consistent with the electrical-permit deferral noted elsewhere in this entry; International Existing Building Code (Art. 10) — 2018 Edition, Ch. 1-16; International Swimming Pool and Spa Code (Art. 11) — 2018 Edition, Ch. 1-11. Source: https://library.municode.com/co/larkspur/codes/municipal_code?nodeId=CH18BURE. The Town Council Meeting Minutes of 4-21-2022 (media ID 2246, hosted on townoflarkspur.org rather than SharePoint) record the adoption: '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.; HB22-1362 (statewide energy code floor) does not impose a flat statewide deadline. Per its own trigger mechanism (as summarized by the Colorado Energy Office, AIA Colorado, and the Southwest Energy Efficiency Project), 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 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 activated, and the Town's 2018 IECC (adopted via Ord. 2022-11) remains its lawfully current energy code. Source: https://library.municode.com/co/larkspur/codes/municipal_code?nodeId=CH18BURE_ART7INENCOCO; 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: the Town publishes no Larkspur-specific plumbing permit fee schedule and no locally-administered plumbing licensing or inspection program separate from the SAFEbuilt-administered Building Permit process. Plumbing review is folded into SAFEbuilt's general building-permit review — the 'PLUMBING ONLY' permit type appears on the Town's own permit-type list and is issued through the same SAFEbuilt/CommunityCore process as other trade permits, rather than being deferred to a state board the way electrical is. 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.' That is why no itemized plumbing valuation-based fee table appears anywhere on the Town's own site: the dollar-amount schedule is Exhibit C of a private Town-SAFEbuilt services contract, not a document the Town routinely publishes. Budget the $30.00 Town administrative fee plus the SAFEbuilt Exhibit C amount, which you will need to get from the Town or SAFEbuilt directly.
