Residential scenario
Historic district window replacement
In an older borough with a historic commission, the review is about what the window looks like from the street. The performance requirements do not go away because of it.

This page describes a representative scope for this project type. It is not a claim about a specific completed job, and no client, address, or date is implied.
What reviewers actually look at
Commissions tend to evaluate the visible geometry: how wide the frame reads from the sidewalk, where the horizontal division sits, whether the muntin pattern matches the original, and whether the glass sits at roughly the same depth in the opening.
A modern unit can meet these criteria, but only if the profile is selected for it. Choosing a system on price and then discovering the sightline is too heavy is the standard way this scope goes sideways.
Performance is not waived
A historic exemption, where it applies, is about appearance and material, not about egress. A bedroom window still has to provide a compliant clear opening, and the energy requirements still apply to the replacement scope unless the specific exception is formally granted.

Every project differs in opening count, condition, and timing. The quote form takes it from there.
