Replacing lead-painted windows
The EPA treats window replacement as covered renovation regardless of square footage, so an EPA-certified firm with a certified renovator does it, with the room sealed and the ground outside covered. Chula Vista’s Form 4551 exempts replacement windows from a building permit when they go into the existing opening with the same operating style and no change to the rough opening, and it notes that owners of eligible or designated historic resources should contact the city’s Historic Preservation Manager first. Where window work on a historical resource does need a building permit, the city code treats same-opening work as a minor alteration and a changed opening as a major one, both needing a certificate of appropriateness; work exempt from building permits needs none.
