Use Boise’s Decision Matrix with the actual property status
Boise’s Certificate of Appropriateness page describes a Decision Matrix based on district, property status and scope. It also explains contributing and noncontributing categories. Use those city resources to prepare a property-specific inquiry rather than assuming that a status label settles the route for a window change. Boise COA and Decision Matrix information.
Ask staff to confirm the relevant property information before following an example from another home. A nearby project may concern a different status or a different extent of work. Keep the actual address and proposal together, including any uncertainty about the existing designation.
Describe the window change beyond its product name
Describe the window beyond its product name. Identify the existing opening, frame, sash and surrounding trim, then state which parts would remain. If a proposed option changes size, material or style, say so explicitly rather than calling every option a repair of the same feature.
Use current photographs and a labeled comparison to discuss the work with a business. Keep an option to retain parts distinct from a complete replacement proposal, and ask what assessment is still needed. Do not select an installation method or infer concealed structural conditions from a picture; those questions belong with the appropriate professional.
Boise City project questions
Why does property status matter before a window change?
Boise’s matrix considers property status alongside district and scope. Ask staff how those factors apply to the actual proposal rather than treating a contributing or noncontributing label as a complete answer.
What should I ask if a Boise property is described as noncontributing?
Ask staff to confirm the property’s status and district, then explain which window parts stay and what size, material or style would change. Bring current photos. Use those facts with the city’s Decision Matrix; a noncontributing label alone does not settle the review route or authorize the work.

For a rented home, confirm who can authorize alterations. In a shared building, ask about access and work rules. A citywide construction period does not establish the age, condition or safety requirements of an individual home; check the property records and the specific project.
