Lakewood, Colorado Building Permits
Lakewood, CO building permit guide with fees, review timelines, zoning, required plans, inspections, wind, snow, flood and wildfire rules.
Wind
ASCE 7 basic wind speed: typically 115 mph ultimate for Risk Category II buildings in much of Lakewood; foothill, exposure, topographic and special wind-region effects must be verified site by site.
Snow Load
Ground snow load: commonly 30 psf in the Lakewood/Denver metro area, with roof snow load adjusted for exposure, drifting, unbalanced snow, roof slope and thermal factors. Higher site-specific design may be required in western or elevated areas.
Flood
Lakewood uses FEMA Flood Insurance Rate Maps and local floodplain regulations. Parcels near Bear Creek, Lakewood Gulch, Weir Gulch, Dry Gulch, Lena Gulch, Turkey Creek or other mapped drainageways may require floodplain development review, elevation certificates and flood-resistant construction measures.
Earthquake
Seismic Design Category: typically B for many standard Lakewood sites, subject to ASCE 7 mapped values, risk category and geotechnical site class. Essential facilities or poor soil conditions can change seismic design requirements.
Wildfire
Wildfire exposure is a meaningful concern in western Lakewood, Green Mountain and foothill/open-space interface areas. Projects may need to address ignition-resistant construction, Class A roofing, ember-resistant vents, defensible space, emergency access and local fire district recommendations, especially near wildland vegetation or steep terrain.

Approval Timeline
Over-the-counter or online trade permits may be issued same day or within several business days when complete. Residential decks, basement finishes, remodels and small additions commonly take 2-4 weeks for first review. New homes and larger additions often take 4-6 weeks. Commercial tenant improvements commonly take 3-6 weeks, while new commercial buildings, restaurants, medical uses, assembly occupancies or projects requiring fire, planning, engineering or outside-agency review may take 6-10+ weeks. Corrections and resubmittals extend the total timeline.
Common Requirements
Common Lakewood permit submittals include the permit application, project valuation, owner and contractor information, site plan, floor plans, framing plans, elevations, building sections, structural details, energy code compliance documents, mechanical/electrical/plumbing plans, equipment specifications and product approvals. New construction and additions usually require a site plan showing setbacks, easements, drainage, utilities, lot coverage and driveway or access information. Commercial submittals typically need a code summary, occupancy and construction type, accessibility details, egress plan, occupant load, fire-resistance assemblies, rated penetrations, emergency lighting, exit signage and fire sprinkler or alarm plans when required.
Zoning Information
Lakewood regulates land use through its zoning ordinance, zoning map and development standards for residential, mixed-use, commercial, industrial and public districts. Zoning review commonly checks use, setbacks, height, lot coverage, parking, accessory structures, landscaping and design standards. Properties in redevelopment areas, planned developments, floodplains, historic areas or hillside/wildland-interface locations may have additional review. A project that changes use, expands a building footprint or affects parking or site design may need planning approval before a building permit is released.
Permit Costs
Lakewood building permit fees are generally valuation-based and may include plan review fees, trade permit fees, use tax and separate fees for fire, zoning or engineering reviews. Simple trade permits may be about $50-$200. Residential remodels, basement finishes and decks often range from a few hundred dollars to more than $1,000 depending on valuation. Additions and new homes often cost several thousand dollars after all building, plan review and tax components are included. Commercial permit costs vary significantly by valuation, occupancy type and required life-safety systems.
Engineering Requirements
Engineer-stamped drawings are commonly required for structural work outside prescriptive IRC limits, removal or alteration of bearing walls, additions, foundation changes, retaining walls over code thresholds, complex decks, steel framing, engineered wood beams, commercial construction and projects with unusual soils, slopes or lateral-load conditions. Lakewood projects in western or hillside areas may need additional geotechnical, drainage or foundation engineering. Commercial construction generally requires Colorado-licensed architects and engineers unless a statutory exemption applies.
Local Code Adoption
Lakewood administers the 2021 International Building Code and 2021 International Residential Code with local amendments, together with related 2021 I-Codes and the electrical code edition adopted by Colorado and the city. Applicants should check Lakewood’s current adopted-code page for effective dates and amendments.
