Mountain View requires 4 inspection(s) for a residential addition / remodel permit, in order: Foundation (additions with new footings only), Rough Framing, Rough Electrical / Plumbing / Mechanical, Final Inspection. Schedule each through Town of Mountain View Building Department (administered by SAFEbuilt under contract) ((303) 450-8746).

Apply through Town of Mountain View Building Department (administered by SAFEbuilt under contract) at Mountain View Town Hall, 4176 Benton Street, Mountain View, CO 80212. Phone: (303) 450-8746, email: Buildingpermits@tomv.org. Office hours: Building division operates weekdays 8:00 a.m.-5:00 p.m. (Town's FAQ page prints this as '8:00 a.m. - 5:00 a.m.', which is evidently a typo for 5:00 p.m. given the Town Hall's own general business hours; noted honestly rather than silently corrected without flagging). Inspection request line (303) 450-8748 — call by 4:00 p.m. for next-business-day inspection. Town Hall main line (303) 421-7282.. Official information: https://www.tomv.org/building-department.

Mountain View, Colorado has adopted: 2021 International Residential Code (IRC) — referenced as the current adopted standard on the Town's 'Helpful Building Permit Handouts' page (page title/meta-description: 'Handouts developed by the Colorado Chapter of the International Code Council as a basic plan submittal under the 2021 International Residential Code') and cross-confirmed on the Town's own Building Permit Application (page 3, Homeowner Electrical/Plumbing certification): 'in accordance with the current edition of the National Electric Code, International Residential Code, and International Plumbing Code adopted by the Town of Mountain View as the minimum standard.'; National Electrical Code (NEC) — current edition, per the same Building Permit Application homeowner-certification language; the Town's live public-facing pages do not print the specific NEC year cycle (e.g. 2020 vs 2023) anywhere checked (Building Department page, Building Permits page, Handouts page, Application PDF) — noted as a gap rather than guessed.; International Plumbing Code (IPC), 2021 Edition — per the Town's own codified Municipal Code §18.08.010 ('International Plumbing Code adopted,' mountainview.municipal.codes/Code/18.8): 'The International Plumbing Code, 2021 Edition... is adopted by reference... The provisions of the International Plumbing Code shall apply to the construction of, and renovations or additions to, all commercial and residential buildings within the Town.' (Ord. 2024-07-15A §17; Ord. 2019-02-11F §1; Ord. 2010-7 §4). The Building Department's public-facing webpages do not print the specific year cycle; the Municipal Code's own codified Article 8 does.; An older page is still online from the Town's previous CivicLive-hosted site (mountainviewco.hosted.civiclive.com/services/building_department_/building_permits, and its townofmountainviewcolorado.org mirror) stating that 'The 2015 International Building Code is the official adopted reference for building codes and applicable to Mountain View, effective March 28, 2019.' That page predates the Town's current SAFEbuilt-administered site at tomv.org and its CommunityCore permitting system. Work from the Town's live Helpful Building Permit Handouts page, which references the 2021 IRC-based ICC Colorado Chapter guides, and confirm the adopted edition with the Building Department before designing to the older page.; The Town's Municipal Code Chapter 18 (Building Regulations, mountainview.municipal.codes/Code/18) adopts the following editions, each quoted directly from its codified section: International Fire Code (IFC), 2021 Edition — §18.05.010 ('The International Fire Code, 2021 Edition... is adopted by reference'; Ord. 2024-07-15A §11), further amended per West Metro Fire Protection District Resolution No. 2022-08 (§18.05.030). International Mechanical Code (IMC), 2021 Edition — §18.07.010 (Ord. 2024-07-15A §14; Ord. 2019-02-11E §1; Ord. 2010-7 §4). International Plumbing Code (IPC), 2021 Edition — §18.08.010 (Ord. 2024-07-15A §17; see also the dedicated IPC codesAdopted entry above). International Fuel Gas Code (IFGC), 2015 Edition — §18.11.010 ('The International Fuel Gas Code, 2015 Edition... is adopted by reference'; Ord. 2019-02-11H §1) — notably NOT bumped to 2021 by the Town's 2024-07-15A omnibus code-update ordinance, unlike every other International code family in Chapter 18; this lag is a real, confirmed feature of the Town's current code. International Existing Building Code (IEBC), 2021 Edition — §18.12.010 (Ord. 2024-07-15A §19; Ord. 2019-02-11G §1). International Energy Conservation Code (IECC), 2021 Edition — §18.045.010 (Ord. 2024-07-15A §9); see also the dedicated HB22-1362 entry below, which this same Article resolves. Every Article states its provisions 'shall apply to the construction of, and renovations or additions to, all commercial and residential buildings within the Town' (near-identical boilerplate in each Article), so none of these adopted codes are residential- or commercial-only carve-outs.; No IBC, IFC, IMC, IFGC, IECC, or IEBC edition is printed anywhere on the Town's live public-facing pages, its Building Permit Application, or its Use Tax Guidelines — Mountain View's public-facing materials are IRC/NEC/IPC-focused. The Town's Municipal Code Chapter 18 (Building Regulations, mountainview.municipal.codes/Code/18) does, however, include dedicated Articles for the IBC (Art. 4, 2021 Edition, Ord. 2024-07-15A/2019-02-11A/2010-7), IRC (Art. 13, 2021 Edition, Ord. 2024-07-15A/2019-02-11I), Fire Code (Art. 5), Mechanical Code (Art. 7), Fuel Gas Code (Art. 11), Existing Building Code (Art. 12), and Energy Conservation Code (Art. 4.5). The IBC and IRC edition years (2021) are confirmed from Articles 4 and 13; the specific edition years adopted in Articles 5/7/8/11/12/4.5 (covering the IFC, IMC, IFGC, IEBC, and IECC) are not stated in the Town's public-facing materials and are not recorded here rather than assumed — see the entry above for the confirmed figures.; The Town has taken its own HB22-1362 adoption action, codified directly in Municipal Code §18.045.010 (Article 4.5, Energy Conservation Code, mountainview.municipal.codes/Code/18.4.5): 'In addition to the IECC, the Town of Mountain View will also be adopting the Colorado Model Electric Ready and Solar Ready Code as required by State law under HB22-1362. These requirements will be in addition to those found in this Code.' (Ord. 2024-07-15A §9). The same Article's amendments (§18.045.020) further amend IECC Sections C401.2 and R401.2 to require commercial and residential buildings, respectively, to 'comply with the Colorado Model Electric Ready and Solar Ready Code.' The codified ordinance itself thus directly and specifically confirms the Town's HB22-1362 compliance action.; Superseded by the entry above; retained for the record. HB22-1362 (Colorado's statewide building energy code / greenhouse-gas-emissions law, requiring local governments to adopt an energy code and, per its later compliance milestones, the Colorado Electric and Solar Ready Code) is not mentioned anywhere on the Town's live Building Department, Building Permits, or Helpful Handouts pages. Given Mountain View's tiny size and thin published program (no separate energy-code page, no mechanical/energy-specific permit-type page), public sources do not establish whether the Town has taken its own HB22-1362 adoption action or is relying on some other mechanism; this is left unresolved rather than stated as fact either way.. Local amendments apply — see the Mountain View overview page for the full list.

Yes. The Town's Building Department FAQ explicitly lists basement finishes (along with kitchen and bathroom remodels) among projects that most people do not realize require a permit.
