How CHAP Changes The Rules For Window Replacement

For many rowhomes and older houses, the windows are part of the building's historic character, so the review process focuses on what stays visible from the street and how closely the new work matches the original look.

• Meeting rails, muntins, and grille patterns
• The trim and surrounding casing, if they are part of the historic facade
