Identify the window before choosing the intervention
Start with the identity of the window, not a replacement model. Ann Arbor’s historic-window resource distinguishes structure status and window installation history, and provides preservation contacts and window resources. Ask staff how those distinctions apply to the actual property before committing to a changed appearance or opening.
For the repair enquiry, label the frame, movable sash, glass and operating hardware separately. A photograph showing the whole elevation explains location; a close view of a failed joint or missing fitting explains the component. Mark what you hope to retain.
Build an assessment request around the part that fails
Describe the symptom in plain terms: the upper sash drops, the lower sash binds at one corner, or a catch no longer meets. Add whether the problem is constant or changes with weather. Ask the assessor to distinguish adjustment, component repair and any proposed alteration.
Keep an assessment request open enough for the condition to be examined. If a new opening is also desired, identify that as a separate proposal. Ask who would assess concealed deterioration and any hazardous finishes rather than assuming a general repair visit covers those questions.
Why does the installation period of a window matter in Ann Arbor?
The City’s resource considers both structure status and window history when discussing possible work. Give preservation staff any reliable information about when the window was installed; ask them to resolve uncertainty for that feature.
How should I separate sash work from a proposal to change the opening?
Use two labeled requests: one for the existing sash and its operating problem, another for the proposed opening dimensions and appearance. Ask for separate assessments so a price for one is not mistaken for the other.

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.
