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.

Permit types & fees
Residential Building Permit (New Single-Family / Two-Family / Multi-Family / Townhome)
Required for construction of new single-family dwellings, two-family dwellings, multi-family townhomes, and new accessory dwelling units in Lafayette. Reviewed under the 2021 IRC/IBC (as adopted by the 2023 Lafayette Colorado Building Code) plus the City's published Design Information (frost depth, snow load, wind speed). Submitted and reviewed entirely by email/electronic plan review; issued by the Planning & Building Department, Building Division.
Residential Addition / Remodel Permit
Covers small residential permits on existing structures/lots (basements, structural and non-structural remodels, decks, patio covers/pergolas, accessory structures, mobile home sets, residential additions under 750 sq ft, gas fireplace/firepit, swimming pools) as well as larger residential additions of 750 sq ft or more, which follow the longer new-construction-style review track. Reviewed under the 2021 IRC as adopted by the 2023 Lafayette Colorado Building Code.
Electrical Permit
Required for installation, alteration, or repair of electrical systems in Lafayette, excluding minor device replacement/repair which is exempt. Falls under the City's Quick Permit category (excluding solar or projects with engineered plans). Governed by the 2023 NEC as adopted. Electrical contractors must hold a Colorado Electrical Board (DORA) state license plus a City of Lafayette Electrical Contractor License (no City license fee).
Plumbing Permit
Required for installation, alteration, or repair of plumbing systems in Lafayette, excluding minor exempt work (same-size/style fixture swaps, leak/stoppage repairs). Falls under the City's Quick Permit category when it excludes engineered plans (grouped with Mechanical as 'Plumbing and/or Mechanical'). Governed by the 2021 IPC as adopted. Plumbing contractors must hold a Colorado Plumbing Board (DORA) state license plus a City of Lafayette Plumbing License.
Mechanical / HVAC Permit
Required for heating, cooling, and ventilation equipment installation or replacement in Lafayette, excluding exempt maintenance/repair work. Falls under the City's Quick Permit category ('Plumbing and/or Mechanical,' plus specifically listed AC and Heating/Furnace items). Governed by the 2021 IMC as adopted. Mechanical contractors must hold a City of Lafayette Mechanical License.
Roofing Permit (Reroof)
Required for any roof work involving one square (100 sq. ft.) or more of shingles in Lafayette. Falls under the City's Quick Permit category, billed at a flat $100 fee. Governed by the 2021 IRC/IBC local roofing amendments (Class 4 Impact Resistant Shingles, ice-and-water shield, drip edge, layer limits) detailed in the City's dedicated Roofing Code Information/Checklist.
Solar Photovoltaic (PV) Permit
Required for residential and commercial solar panel installations in Lafayette. The City is a certified Solar Friendly Community with a specific, published 3-business-day permit-issuance commitment, a flat $100 residential fee, and a detailed structural/electrical submittal checklist. Governed by the 2023 NEC, adopted without amendments for solar PV work.
EV Charger / EVSE Permit
Electric vehicle charging equipment (EVSE) installation in Lafayette is processed as ordinary electrical work under the City's 'Quick Permit' category (Electrical, excluding Solar or projects with engineered plans), governed by the 2023 NEC as adopted. The City's Building Permit Fee Schedule (Exhibit A, effective 1-1-26) lists a flat $100 fee only for a specific named list of residential categories (AC, Furnace, Fence, Roof, Sewer Repair, Shed, Siding, Solar PV, Water Heater, & Windows) — EV chargers/EVSE are NOT on that list, so a standalone EVSE circuit is billed under the general valuation-based fee table instead. Under Colorado's HB24-1173 (Electric Vehicle Charging System Permits Act), Lafayette qualifies as a 'covered municipality' (population over 10,000) and was required to take a compliance action by December 31, 2025; the City adopted Resolution No. 2025-74, electing to continue using its existing permitting review process rather than adopting the Colorado Energy Office's EV charger model land use code or a new expedited standards/review process.
Solar Thermal Permit
Required for solar thermal (hot water/hydronic) system installations in Lafayette. Distinct from the Solar PV permit, with its own submittal checklist, a published 3-working-day review commitment, and its own residential flat fee ($63) that the City states is significantly lower than many other Colorado communities.
Accessory Dwelling Unit (ADU) Permit
Required for construction of a new Accessory Dwelling Unit in Lafayette. New ADUs are classified with New Single-Family/Two-Family/Multi-Family permits under the City's longer new-construction review track, distinct from the faster Quick/Small Residential tracks. The City publishes separate checklists for detached ADUs (or ADUs requiring an addition) versus attached ADUs that do not require an addition.
Fence Permit
Required for residential and commercial fences in Lafayette, billed at the Exhibit A flat $100 fee alongside AC/Furnace/Roof/Siding/Solar PV/Water Heater/Windows. The City publishes a dedicated Fence checklist covering both residential and commercial fences.
Demolition Permit
Required for demolition, moving, or occupancy-change of any building or structure in Lafayette. Structures 50 years or older trigger mandatory Historic Preservation Commission (HPC) review, which may stay permit issuance for up to 90 days. Fees differ sharply depending on whether HPC review applies.

Tips & gotchas
- Lafayette is a home-rule city with its OWN Planning & Building Department (1290 S. Public Road) — it is NOT served by Boulder County's unincorporated permitting program.
- Lafayette publishes an unusually granular, explicit set of processing-time tiers by project category: Quick Permits (2 business days — electrical excluding solar/engineered plans, plumbing/mechanical excluding engineered plans, AC, heating/furnace, roofs [2-3 working days per the dedicated roofing checklist], water heaters, water/sewer repairs, siding/windows without structural changes), Small Residential Permits (2-3 weeks — basements, remodels, decks, patio covers/pergolas, accessory structures, mobile home sets, additions under 750 sq ft, gas fireplace/firepit, swimming pools), Residential new-construction-tier permits (8-12 weeks for first comments, 1-2 weeks per subsequent review — new single-family/two-family/multi-family/ADU and additions 750 sq ft or larger), Commercial Tenant Finish (2-4 weeks for first comments), and Commercial Addition/New Commercial/New Multi-Family (4-8 weeks for first comments, requiring Site Plan/Architectural and Civil CD approval BEFORE permit submittal).
- Solar PV remains Lafayette's fastest-turnaround permit category: a City-stated goal of 3-business-day issuance and a flat $100 residential PV fee, both confirmed on live City sources as of 2026-07-16 (Solar Permit Application Process PDF and the Exhibit A Fee Schedule). Note that solar is explicitly EXCLUDED from the general 2-business-day Quick Permit track, so the 3-business-day solar goal is its own separate figure. Caveats as of 2026-07-16: the City removed its solar webpages and consolidated them into PDFs, and three previously-published solar claims now survive on no live source — the $63 residential SOLAR THERMAL fee and its 3-working-day review figure (the City's current solar materials are photovoltaic-only, and the live Fee Schedule has no solar-thermal line), and the promotional '76% below the national average' / $500 COSEIA Solar Friendly Community discount claims. Treat those three as last-published rather than current, and confirm with the Building Division (303-661-1451).
- All plan submittals are ELECTRONIC-ONLY by email (or Dropbox/FTP for large files) to buildingpermits@lafayetteco.gov — paper copies are explicitly not accepted, and emails over 25MB will not be received.
- Contractor licensing is two-layer: a Colorado DORA state trade license (electrical, plumbing) PLUS a separate City of Lafayette contractor license via the MyGov portal. Notably, Lafayette charges NO City fee for the Electrical Contractor License itself (only requires the State license copies), while General (A/B/C), Mechanical, Plumbing, and Special licenses carry $100-$175 fees.
- Demolition of any structure 50 years or older triggers mandatory Historic Preservation Commission review, which can stay permit issuance for up to 90 days (appealable to City Council) — and roughly doubles the application fee ($300 + Public Hearing Fee vs. $150 without HPC review).
- Roofing has its own dedicated, highly detailed local rulebook: Class 4 Impact Resistant Shingles required since March 15, 2021, mandatory ice-and-water shield and drip edge, max two asphalt layers, and a distinctive ONE-final-inspection policy (no mid-roof inspection) with strict ladder/pitch/weather rules enforced by a $75 reinspection fee.
- Lafayette's Building Permit Fee Schedule (Exhibit A/B/C/D) is dated effective 1-1-26 and states all fees are 'subject to change without notice' — confirm current figures with the Building Division (303-661-1451) before quoting fees to a client.
- The City levies both a City Use Tax (3.87% of 60% of value) and a Boulder County Use Tax (1.335% of 60% of value) on top of the base permit fee — a combined use-tax burden that should be factored into total permit cost estimates.
- Old Town Lafayette carries its own overlay-district requirements (Old Town Neighborhood Overlay District Regulations and Dimensional Standards) layered on top of the base building code for additions, duplexes, garages, ADUs, and other accessory structures — always check whether a parcel falls in this district before finalizing plans.
- Colorado's Wildfire Resiliency Code (adopted statewide 2025) affects a specific, mapped 128 acres within Lafayette (44 acres of open space on the southeast edge, 84 acres near Nyland Way/Brittney Lane on the west side) — check the Resiliency Code Map before assuming a parcel is unaffected.
