Window Replacement Permit
Window Replacement Permit Guide
Window permits depend on whether the opening changes, safety glazing is required, bedroom egress is affected, or energy-code documentation applies.
Permit likelihood
Often required when window size, structure, egress, safety glazing, or exterior weatherproofing details change.
Typical permit cost
$50-$300 for many replacement permits; plan review can cost more when openings are resized.
Planning timeline
Same day to three weeks depending on whether structural changes or energy documentation are required.
