The Situations That Commonly Trigger Review

A permit is most often needed when the job is more than a simple unit-for-unit change. Any change that affects size, structure, or safety tends to move the project out of the "simple replacement" bucket.

The age and location of the house matter just as much as the scope of work. Homes subject to preservation review often need the replacement to match the original look closely enough that the street view stays consistent.

What Reviewers Look For In Historic And Older Homes

How Window Approval Usually Works In DC

Most delays come from missing details, not from the process being impossible. First comes the scope check, because the application for a repair is not the same as the one for a replacement or modification.
