Egress Windows in Morrison, Edgewater & Unincorporated Jefferson County

Last updated October 25, 2026

Morrison, Edgewater and unincorporated Jefferson County each have their own permit office, and all three require permits for egress or window-size changes.

Morrison (Town)

• Permit office: the Town of Morrison Building Department, run under contract by Charles Abbott Associates (Building Department).
• Apply with the online Building Permit Application. Inspection requests are due by 4:00 PM on the business day before (same page).
• The Town's application form lists "Remodel / Finish" and "Repair/Replacement", with fee lines for permit fee, plan review and use tax (application PDF).
• Code edition: Ordinance 563 (July 7, 2026) adopted the 2024 International Residential Code and 2024 International Building Code (Town Board packet; Morrison Municipal Code). The application form's "2015 IBC ADOPTED" header predates that ordinance.
• Fees: set by the town; see the official Fee Schedule for current amounts.

Edgewater (City)

• Permit office: City of Edgewater Community Development. Building division services are performed by SAFEbuilt, and applications go through the CommunityCore portal (Building & Planning FAQs).
• Permits are required for "Installation or replacement of windows or doors (required U-factor .30 U-factor or less)" and for any "Increase or decrease of window or door size", as well as basement finishes (FAQ).
• Fees: based on total project value; see the official 2024 Fee Schedule on Documents and Fees for current amounts.
• A homeowner permitting their own home doesn't need a contractor license. Any contractor they hire must be licensed with the city (FAQ).

Unincorporated Jefferson County (Conifer, Indian Hills, Lakeside-area unincorporated addresses)

• Permit office: Jefferson County Building Safety, 100 Jefferson County Parkway, Suite 3540, Golden, CO 80419; 303-271-8260; Mon–Thu 8 a.m.–5 p.m., appointments for plan review (Emergency Escape & Rescue Openings).
• Egress windows are listed among projects that need a Building Permit. Permits get a two-part review (Planning & Zoning plus Building Safety), and new bedrooms need both. Septic properties are limited by their On-Site Wastewater permit, and a basement finish with a kitchen may be reviewed as an ADU (Inside the Home).
• Code: the county's egress page quotes the 2024 IRC (R319) and states that new sleeping rooms in an existing basement need an escape opening, while other basement alterations do not (same EERO page).
• Fees: estimate with the county's Building Safety Fee Estimator. Unincorporated Jefferson County does not charge use tax (Fees).
• Evergreen has its own page: /evergreen-egress-windows/.

FAQ

• I'm in Edgewater replacing a basement window. Does U-factor matter? Yes. Edgewater's permit list sets a U-factor of 0.30 or less for replacement windows.
