How To Tell Whether Your Project Is Same-Size Replacement Or Structural Change

A few questions usually clarify the scope quickly.

• Will the rough opening stay the same size?
• Are you changing the header, sill, or jack studs?
• Does the opening need to meet escape requirements?
• Is the house in a historic district or under an HOA?
• Will exterior trim, masonry, or siding be disturbed?
