Arvada, Colorado Building Permits
Learn Arvada, Colorado building permit steps, fees, timelines, code requirements, zoning reviews, and when engineered plans are needed for local projects.
Wind
ASCE 7 basic wind speed: commonly 115 mph Vult for Risk Category II in the Denver metro area, but Arvada sites near foothill wind zones, open exposure, or special wind regions may require higher site-specific design speeds and exposure analysis.
Snow Load
Ground snow load: typically 30 psf for Arvada-area design, with roof snow load calculated under the adopted code based on exposure, thermal condition, drifting, slope, and local amendments.
Flood
FEMA floodplain regulations apply in mapped Special Flood Hazard Areas, including areas near Ralston Creek, Leyden Creek, Little Dry Creek, Van Bibber Creek, and other drainage corridors. Projects in or near a floodplain may require floodplain review, elevation data, drainage studies, lowest-floor documentation, and compliance with FEMA and city flood damage prevention standards.
Earthquake
Seismic design category is typically B for ordinary residential sites, but the final category depends on the adopted code, mapped spectral response values, risk category, and site class from geotechnical information.
Wildfire
Western Arvada and properties adjacent to open space, grassland, or foothill interface areas can face elevated wildfire and grassfire exposure. Fire access, defensible space, ignition-resistant exterior materials, address visibility, hydrant access, and roof covering requirements may be reviewed by the city and fire authority depending on location and project type.

Approval Timeline
Simple residential trade permits are often issued same day to a few business days if the contractor is licensed and the scope is clear. Residential decks, basement finishes, remodels, additions, and new homes commonly take about 2-4 weeks for first review, depending on completeness and workload. Commercial tenant improvements often take about 3-6 weeks for first review, and new commercial buildings or projects requiring fire, engineering, utility, drainage, floodplain, or planning approvals can take longer. Resubmittals commonly add 1-2 weeks per review cycle.
Common Requirements
Typical Arvada permit submittals include a completed permit application, project valuation, contractor information, a dimensioned site plan, construction drawings, floor plans, elevations, wall sections, framing plans, structural details, energy-code compliance documentation, and manufacturer specifications for items such as trusses, beams, windows, mechanical equipment, fireplaces, solar systems, and prefabricated components. New homes and additions commonly require a foundation plan, soils report or foundation design information, drainage/grading information, and utility service details. Decks typically need a plot plan, footing sizes, beam and joist spans, guard/handrail details, stair details, and ledger attachment information. Commercial projects usually require code analysis, occupancy classification, construction type, accessibility details, life-safety plans, egress calculations, fire-resistance assemblies, mechanical/electrical/plumbing sheets, and sometimes fire sprinkler or alarm drawings.
Zoning Information
Arvada administers zoning through its Land Development Code, with residential, mixed-use, commercial, industrial, employment, open-space, planned development, and overlay districts. Zoning review generally checks allowed use, setbacks, lot coverage, building height, parking, accessory structures, ADUs, landscaping, historic or Olde Town requirements, and floodplain or drainage constraints. A building permit does not override zoning limits, private covenants, or HOA approvals.
Permit Costs
Arvada permit fees are generally based on project valuation, with separate plan review fees and possible city use tax, technology fees, state or county surcharges, and trade permit fees. Small trade permits may be roughly $75-$250. Decks, basement finishes, windows, and minor remodels often range from a few hundred dollars to $1,500 or more. Additions, ADUs, and major remodels may run $1,000-$5,000+, while new homes can exceed $5,000-$15,000 when building permit, plan review, use tax, utility, and impact-related charges are included. Final fees must be calculated by the city from the adopted fee schedule and declared valuation.
Engineering Requirements
Engineer-stamped plans are commonly required in Arvada for non-prescriptive structural work, new custom homes, additions with new foundations, significant beam or load-bearing wall changes, foundation repairs, retaining walls over about 4 feet or supporting surcharge, tall freestanding walls, unusual deck designs, commercial structural work, and projects affected by expansive soils, floodplain conditions, or site-specific geotechnical recommendations. Solar PV, rooftop equipment, and roof-mounted systems may require structural verification if loads or attachment conditions exceed prescriptive limits.
Local Code Adoption
Arvada currently enforces locally adopted International Codes with city amendments, commonly based on the 2021 IBC, IRC, IEBC, IMC, IPC, IFGC, IECC, and related codes, plus the Colorado-adopted National Electrical Code. Applicants should verify the current code cycle and amendments with the City of Arvada before design because local amendments and state electrical/plumbing rules can change.
Typical Projects
Common permitted projects in Arvada include basement finishes, decks and patio covers, kitchen and bathroom remodels, additions, ADUs, detached garages, window and door replacements, roof replacements, solar PV systems, EV chargers, furnace/AC/water heater replacements, tenant improvements, restaurant build-outs, office and retail remodels, and new single-family homes in infill and developing neighborhoods.
