Codes adopted
Colorado has no statewide-mandated building code edition. Under the Colorado Constitution's home-rule provisions (art. XX, home rule for municipalities since 1902; home rule for counties since 1970), building codes and zoning are an enumerated home-rule charter power, so cities and counties adopt and amend their own construction codes independently — predominantly the I-Codes, with editions and local amendments varying by jurisdiction. The one statewide floor is for energy: HB22-1362 (2022) created the Energy Code Board (jointly appointed by the Colorado Energy Office and the Department of Local Affairs) and requires that, on or after July 1, 2023 and before July 1, 2026, any municipality or county that adopts or updates a building code must adopt and enforce an energy code achieving performance equivalent to or better than the 2021 IECC together with the board's Model Electric Ready and Solar Ready Code (which includes electric-ready, EV-ready, and solar-ready provisions); from July 1, 2026 onward the floor shifts to the board's Model Low Energy and Carbon Code or an equivalent. Electrical and plumbing permitting defaults to the Colorado State Electrical Board and State Plumbing Board (within DORA's Division of Professions and Occupations) — the state issues permits and inspects statewide except in counties/jurisdictions that operate their own certified Electrical or Plumbing Inspection Program, in which case the local program has authority instead. Always confirm the currently adopted code edition, local amendments, and inspection authority (state board vs. local program) with the specific jurisdiction before submitting plans.
- 2024 International Building Code (IBC), Chapters 1-35 — CONFIRMED 2026-07-23 directly from the Town's own codified ordinances (Sec. 18-2-10, 'Adoption', Chapter 18 — Building Regulations, Article II — Building Code): 'The International Building Code, 2024 Edition as published by the International Code Council, 4051 West Flossmoor Road, Country Club Hills, IL 60478, Chapters 1 through 35 inclusive...' Retrieved live via Municode Library (library.municode.com/co/platteville/codes/code_of_ordinances), Code of Ordinances Supplement 2, online content updated 2026-02-17, codified through Ordinance No. 2025-851 (enacted 2025-12-16) — the Dec-2025 code-adoption ordinance referenced in this corpus's Colorado research playbook.
- 2024 International Residential Code (IRC), Chapters 1-43 — CONFIRMED 2026-07-23 via Sec. 18-10-10 'Adoption' (Chapter 18, Article X — Residential Code): 'The International Residential Code, 2024 Edition as published by the International Code Council... Chapters 1 through 43 inclusive...' Corroborates the SAFEbuilt guide series' consistent '2024 IRC' heading with a second, independent, directly-codified source.
- 2024 International Mechanical Code (IMC), Chapters 1-15 — CONFIRMED 2026-07-23 via Sec. 18-3-10 'Adoption' (Chapter 18, Article III — Mechanical Code), live Municode text.
- 2024 International Fuel Gas Code (IFGC), Chapters 1-8 — CONFIRMED 2026-07-23 via Sec. 18-9-10 'Adoption' (Chapter 18, Article IX — Fuel Gas Code), live Municode text.
- 2024 International Fire Code (IFC), plus Appendix B-0 — CONFIRMED 2026-07-23 via Sec. 18-11-10 'Adoption' (Chapter 18, Article XI — Fire Code): 'chapters and appendices B-0 of the 2024 International Fire Code (the "IFC") are hereby adopted by reference as the Town of Platteville Fire Code...'
- 2024 International Property Maintenance Code (IPMC), Chapters 1-8 — CONFIRMED 2026-07-23 via Sec. 18-12-10 'Adoption' (Chapter 18, Article XII — Property Maintenance Code), live Municode text.
- 2024 International Existing Building Code (IEBC), Chapters 1-16 — CONFIRMED 2026-07-23 via Sec. 18-13-10 'Adoption' (Chapter 18, Article XIII — Existing Building Code); this code family was not previously identified in this file — new finding from the 2026-07-23 chase.
- 2024 International Energy Conservation Code (IECC), Chapters 1-6 Commercial [+ Residential provisions] — CONFIRMED 2026-07-23 via Sec. 18-14-10 'Adoption' (Chapter 18, Article XIV — Energy Conservation Code), which ALSO adopts by reference 'Appendix CK Colorado Model Electric and Solar Ready Code-Commercial and Appendix RM Colorado Model Electric and Solar Ready Code-Residential' — this is the direct, specific HB22-1362 electric-ready/solar-ready citation that could not be located in 2026-07-06's chase (only the generic 'State of Colorado Electric Ready Code' guide reference was found then). Sec. 18-14-30 'Amendments' further amends the IECC to replace all references to 'ICC Electrical Code' with 'National Electrical Code as adopted by the State.'
- National Electrical Code (NEC), 2023 Edition, exclusive of appendices — CONFIRMED 2026-07-23 via Sec. 18-5-10 'Adoption' (Chapter 18, Article V — Electrical Code): 'The National Electrical Code, 2023 Edition, exclusive of appendices, published by the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02169, is hereby [adopted]...' This RESOLVES the gap flagged in the 2026-07-06 pass ('The NEC edition... could not be independently re-confirmed... omitted rather than guessed') — Platteville does codify its own NEC edition (2023) in Chapter 18 Article V, notwithstanding that day-to-day electrical licensing runs through DORA contemporaneous review rather than a Town trade-license program (see localAmendments).
- All nine code-family adoptions above were retrieved 2026-07-23 from the Town's live, current Municode Library codification (library.municode.com/co/platteville/codes/code_of_ordinances), Supplement 2, online content updated 2026-02-17, 'Codified through Ordinance No. 2025-851, enacted December 16, 2025' — via that page's own full-text search API (localapi/search, clientId=19046, scoped to Platteville only), which returns live indexed section text. This is a second, independent, more authoritative confirmation of the 2024 cycle than the SAFEbuilt guide series alone, and definitively supersedes the stale 'Photovoltaic System Submittal Requirements' PDF (last revised 10.22.2021, citing '2020 NEC, 2018 International Codes') — that PDF's code-year language is now confirmed stale against the Town's own codified ordinances, not merely inferred against a differently-dated guide series.
- Colorado is a home-rule state with no statewide-mandated building code edition; Platteville's own codified Chapter 18 adoption ordinances (as amended through Ord. No. 2025-851, Dec. 16, 2025) are the direct governing source, corroborated by the SAFEbuilt guide series.
- HB22-1362 (Colorado's statewide minimum energy code floor for the July 2023-July 2026 window, requiring at least the 2021 IECC plus electric- and solar-ready / EV-ready provisions for jurisdictions issuing residential building permits) is satisfied and directly evidenced: Platteville's 2024 IECC adoption (Sec. 18-14-10) exceeds the 2021 IECC floor AND explicitly adopts by reference the Colorado Model Electric and Solar Ready Code Appendices CK (Commercial) and RM (Residential) — the specific state-mandated electric-ready/solar-ready provisions, confirmed 2026-07-23 directly from the ordinance text rather than inferred from a generic guide-page mention.
Permit types & fees
Residential Building Permit (New Construction)
Required for new single-family home construction in the Town of Platteville. Reviewed under the 2024 IRC as adopted; plan review and inspections are performed by SAFEbuilt on the Town's behalf, while the Town separately assesses its own utility and impact fees on the same combined application.
Residential Addition / Basement Finish Permit
Required for additions to single-family dwellings and residential basement finishes in Platteville. Reviewed under the 2024 IRC as adopted, per the Town's dedicated SAFEbuilt guides for each scope.
Electrical Permit
Required for electrical installation, alteration, or repair in Platteville. Platteville does not run its own local electrician licensing program; the Town instead performs contemporaneous review of each electrician's Colorado State Electrical Board (DORA) license per CRS 12-23-116, as its own published guidelines describe. Separately, the Town DOES codify its own technical electrical code: Chapter 18, Article V, Sec. 18-5-10 adopts the National Electrical Code, 2023 Edition (confirmed live 2026-07-23), which governs installation standards independent of the DORA licensing question.
Plumbing Permit
Required for plumbing installation, alteration, or repair in Platteville. Like electrical, Platteville does not run its own local plumber licensing program; the Town performs contemporaneous review of each plumber's Colorado State Plumbing Board (DORA) license per CRS 12-155-120(1) and HB19-1086.
Mechanical / HVAC Permit
Required for heating, cooling, and ventilation equipment installation or replacement in Platteville, reviewed under the 2024 IRC/IECC as adopted. Issued as part of the combined Building Permit Application (HVAC contractor field).
Re-Roof Permit
Required for residential re-roofing in Platteville, reviewed under the 2024 IRC as adopted per the Town's dedicated Residential Re-roofing guide.
Rooftop Solar / Photovoltaic Permit
Required for solar panel installation or replacement in Platteville. SAFEbuilt's Photovoltaic System Submittal Requirements document specifies structural and electrical plan requirements; the code-edition citation in this specific PDF is stale (2021) relative to the Town's current 2024 IBC/IRC/IECC and 2023 NEC as codified in Chapter 18 (CONFIRMED live 2026-07-23 directly from the Town's own ordinance text, not merely inferred from the guide series — see codesAdopted), and is flagged as such rather than treated as governing.
Demolition Permit
VERIFIED-NEGATIVE, confirmed 2026-07-23: Platteville has no dedicated demolition permit type. Not separately documented on the Town's SAFEbuilt Permits page or in any of the Town's published SAFEbuilt guide series; the Building Permit Application form's 'Type of Improvement' checklist does not include a distinct demolition category (it lists New Building/Structure, Addition, Accessory Structure, Remodel/Finish, Repair/Replacement, Mobile Structure, Sprinkler System, Fence, Water Heater, HVAC, and Other). This was further confirmed 2026-07-23 by a live full-text search of the Town's ENTIRE current Code of Ordinances (Municode Library, Code of Ordinances Supp. 2, updated 2026-02-17, codified through Ordinance No. 2025-851, Dec. 16, 2025) — searching 'demolition permit' across the whole live code returns only 2 hits, both in Chapter 7 (Health, Sanitation and Animals) listing an abandoned/partially-demolished structure as a NUISANCE condition (Sec. 7-1-30/7-1-40), not a permit requirement. Zero hits appear in Chapter 18 (Building Regulations) or Appendix A (Fee Schedule). A demolition project in Platteville would be captured under the standard Building Permit Application's 'Other' checkbox (or possibly under Chapter 18's adopted International Existing Building Code, which governs alteration/demolition of existing structures generically, without a Town-specific standalone demolition-permit process).
Deck, Patio Cover & Carport Permit
Required for uncovered decks/porches and for patio covers/carports in Platteville, reviewed under the 2024 IRC as adopted per the Town's two dedicated SAFEbuilt guides (Uncovered Decks & Porches; Patio Covers/Carports).
Accessory Structure Permit (Detached Garage, Shed, Pole Barn) & Accessory Dwelling Unit (ADU)
Platteville's published SAFEbuilt guide series covers Accessory Structures (garages, sheds) and Pole Barns generically under the 2024 IRC. RESOLVED 2026-07-23: Platteville DOES have a dedicated Accessory Dwelling Unit zoning framework — Chapter 16 (Zoning), Article III, Sec. 16-3-20 'Accessory Dwelling Units,' confirmed live via the Town's Code of Ordinances (Municode Library, Supp. 2, updated 2026-02-17, codified through Ordinance No. 2025-851, Dec. 16, 2025). Live-quoted: each ADU 'shall comply with the principal structure standards, except that each ADU shall be subordinate to and no larger than seventy-five percent (75%) of the square feet [of the principal dwelling unit]'; and 'no portion of a structure containing an ADU may have ownership different from the ownership of the principal dwelling unit' (an ADU cannot be sold or subdivided off from the primary residence). Sec. 16-2-40 'Agricultural/Holding (A-H) District' further confirms an 'Agricultural accessory dwelling unit/structure, limited to nine hundred (900) square feet per acre of land' as a permitted use in that zoning district specifically. A habitable ADU is therefore permitted by right in at least some Platteville zoning districts (subject to the 75%-of-principal-structure size cap and single-ownership rule), but which OTHER zoning districts (beyond A-H) allow ADUs, and any district-specific size/setback variations, were not independently enumerated in this pass — building-permit processing for an ADU is expected to follow the same combined Building Permit Application / SAFEbuilt review path as any other accessory structure or addition, under the 2024 IRC.
EV Charger / EVSE Permit
Platteville has no EV-charger-specific permit type or fee line. An EV charger (EVSE) circuit is electrical work and follows the Town's general Electrical Permit path: filed on the combined Building Permit Application's Electrician field, with the Town performing contemporaneous verification of the installing electrician's Colorado State Electrical Board (DORA) license per CRS 12-23-116, and billed under the Electrical line item on the SAFEbuilt-administered fee block. Appendix A of the Municipal Code IS now confirmed live and publicly reachable (2026-07-23, via the Browser pane against Municode Library) and carries no EV-charger-specific or standalone electrical-only dollar line — a verified-negative that Platteville does not price EV-charger electrical work separately. Colorado's HB24-1173, which mandates EV-charger permit checklists and a 3-business-day decision timeline, only applies to municipalities with 10,000+ residents; Platteville's population (roughly 3,000) is below that threshold, so the statewide mandate does not currently bind the Town. The technical NEC edition governing EVSE circuit installation is now confirmed: 2023 NEC (Chapter 18, Article V, Sec. 18-5-10).

Tips & gotchas
- Platteville contracts with SAFEbuilt for building plan review and inspections (the 'SAFEBuilt Permits' program), but applications, intake, and Town-specific fees (utility/impact fees) remain with Town Hall (400 Grand Avenue, 970-785-2245, kcampos@plattevillegov.org) — expect a split fee structure ('TOTAL SAFEbuilt Fees' vs. 'TOTAL Platteville Fees') on the same combined application.
- Electrical and plumbing permits in Platteville are NOT locally licensed trades — the Town instead performs contemporaneous verification of each contractor's Colorado DORA state license (CRS 12-23-116 for electricians; CRS 12-155-120(1) and HB19-1086 for plumbers) at application and again if the tradesperson changes mid-project. An inspector can fail an inspection at their sole discretion if they cannot verify the identity/licensure of the electrician or plumber who performed the work.
- RESOLVED 2026-07-23: the Town's own codified ordinances (Chapter 18, live via Municode Library, codified through Ordinance No. 2025-851, enacted 2025-12-16) confirm the FULL current code suite by direct citation: 2024 IBC, IRC, IMC, IFGC, IFC, IPMC, IEBC, and IECC (with Colorado Model Electric/Solar Ready Appendices CK/RM), plus 2023 NEC (Article V). This is a second, independent, directly-codified confirmation beyond the SAFEbuilt guide series, and definitively supersedes the stale Photovoltaic System Submittal Requirements PDF (10.22.2021, '2020 NEC, 2018 International Codes'). The NEC-edition gap flagged in the 2026-07-06 pass is now resolved: 2023 NEC.
- RESOLVED 2026-07-23: Appendix A of the Municipal Code IS reachable — the Municode Library page (library.municode.com/co/platteville/codes/code_of_ordinances) is a client-rendered SPA that returns only an empty shell to a raw `curl`, but renders real content in the Browser pane with no login wall. Live-quoted figures now on file: $50.00 residential zoning-compliance surcharge on the base Building Permit (Sec. 16-3-10); $500/$1,000 residential/commercial solar cap (Resolution 2011-26); $25.00 Fence/Hedge/Wall; $200.00 Appeal of Building Official Ruling; and a full development-impact-fee schedule (police/public facilities/parks/transportation/storm drainage/schools/PGFPD, each with real per-unit or per-sq-ft dollar figures). A live full-text search of the entire current Code of Ordinances additionally confirms (verified-negative) that no separate town-specific valuation-based dollar table exists for the base Building/Electrical/Plumbing/Mechanical permit fee beyond what's listed here — that base fee follows the adopted 2024 IBC's own fee schedule by reference through Chapter 18, not a locally-republished figure. Every fee field in this file remains honestly marked rather than invented; the ones now closed are cited to Appendix A or the entire-code search directly.
- No numeric plan-review turnaround (days or weeks) is published anywhere in the Town's materials, the SAFEbuilt guide series, or (re-confirmed 2026-07-23) the Town's entire live Code of Ordinances — every guide states only that review time depends on plan completeness, with no committed SLA. Colorado is home-rule with no statewide review clock.
- IMPORTANT jurisdiction-name caution for future research: 'platteville.org' is the City of Platteville, WISCONSIN — a completely different municipality with its own separate municipal code (including its own 'Chapter 23 Building Code'). Do not conflate WI Platteville sources with the Town of Platteville, COLORADO covered in this file; this mix-up appeared in general web search results during this review and was explicitly screened out.
- The Town's Residential Re-roofing guide explicitly notes that impact-resistant shingles are NOT required in Platteville, calling out that this requirement applies only in the (separate) Town of Timnath, another SAFEbuilt-served Colorado jurisdiction — a useful negative confirmation that shows the guide series is shared template content across SAFEbuilt's client towns, with jurisdiction-specific carve-outs called out where they differ.
- Two guides (Residential Re-roofing and Patio Covers/Carports) list an inspection-scheduling email of 'windsor@safebuilt.com' rather than a Platteville-specific address — almost certainly a leftover template artifact from another SAFEbuilt client jurisdiction (the Town of Windsor, CO). The Town's own primary contact (kcampos@plattevillegov.org, 970-785-2245) should be used instead.
- RESOLVED 2026-07-23: the Town's Municipal Code page confirms building/development regulations sit in 'Chapters 15-18' of the Municipal Code, and those chapters are now confirmed reachable and live-quoted via the Municode Library Browser-pane render (see codesAdopted for the specific Chapter 18 code-adoption ordinance citations, and Sec. 16-3-20 for the Chapter 16 Accessory Dwelling Units zoning section).
- HB22-1362's statewide energy-code floor (2021 IECC minimum, July 2023-July 2026 window) is satisfied and now DIRECTLY evidenced: Platteville's 2024 IECC adoption (Sec. 18-14-10, exceeding the 2021 IECC floor) explicitly adopts by reference the Colorado Model Electric and Solar Ready Code, Appendix CK (Commercial) and Appendix RM (Residential) — the specific state-mandated electric-ready/solar-ready provisions, confirmed 2026-07-23 directly from the ordinance text (previously only a generic 'State of Colorado Electric Ready Code' guide-page mention was found).
- Accessory Dwelling Units ARE a recognized, regulated zoning use in Platteville (Chapter 16, Sec. 16-3-20 — confirmed 2026-07-23), capped at 75% of the principal dwelling's square footage with a single-ownership requirement; the Agricultural/Holding (A-H) district additionally allows a 900-sq-ft-per-acre agricultural ADU (Sec. 16-2-40). See adu-permit.
- Platteville has confirmed NO dedicated demolition permit type (verified-negative via full-text search of the entire live Code of Ordinances, 2026-07-23) — see demolition-permit.
