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.
Reviewed July 26, 2026
Often required when window size, structure, egress, safety glazing, or exterior weatherproofing details change.
$50-$300 for many replacement permits; plan review can cost more when openings are resized.
Same day to three weeks depending on whether structural changes or energy documentation are required.
Cost and timing ranges are general planning examples, not local quotes. Verify the current fee schedule, review queue, and inspection availability with the offices serving the property.
