Which forms does Boulder require for a basement finish permit?
Every Boulder building permit application needs a Scope of Work form for the type of home. The form comes in versions for detached homes, attached homes like townhomes and accessory structures. Basement jobs often add a plumbing fixture count form. That form is required whenever the number, type or location of plumbing fixtures changes. Keep a copy of every form with your permit records.
Applications go through the city's Customer Self-Service Portal. Boulder says submitting online cuts processing time by one to two business days. The city also offers a property information search that shows earlier permits on your home.
Does a Boulder basement finish need an asbestos test?
It does when the work disturbs suspect materials above set amounts. Boulder then needs an asbestos inspection report from a certified inspector. Your contractor arranges the test when it applies. The city warns that buildings of any age may contain asbestos.
Testing used to be regulated by the Boulder County Health Department. It is now part of the city's permit process. Older ceiling texture, joint compound and some flooring are common places to test before demolition.
How does Boulder's energy code affect a basement finish?
Most Boulder permits must show compliance with the city's 2024 energy conservation code, known as COBECC. The exceptions include qualifying repairs and unheated additions outside the thermal envelope, such as decks.
A basement finish creates heated living space, so energy compliance goes into the plan set. Your contractor downloads the city's energy code documents and completes them. Settle insulation and lighting choices early so they appear in those documents.
Is my Boulder basement in a floodplain?
Check the city's floodplain map or request a structure determination through the self-service portal. Projects in a regulatory floodplain need a floodplain development permit filed with the building permit.
Work in the conveyance or high hazard zones may need approval before the building permit application. Ask the city for a determination early. Wetlands, historic districts and individual landmarks can bring extra approvals too, so check each map layer before the design is final.
