Permits for window replacement
Grand Prairie Building Inspections says a residential window or door replacement permit is required for some replacements, and its page ties the requirement to light and ventilation, bedroom egress, keeping new openings no smaller than the originals, and changes to rough framing. The city lists processing at approximately 5 to 10 business days. The page does not mention lead, so the permit and lead-safe work are separate requirements; ask the city whether your job needs one.
Why sills matter in homes with children
Window sills sit at a small child’s height, and paint chips and dust collect on them. Federal lead rules single out children under six: housing that would otherwise be exempt from the renovation rule, such as a unit with no bedroom or housing reserved for older or disabled residents, comes back under it when a child under six lives there. If a child lives in or visits the house, say so in your request so sills are part of testing and cleanup. Health questions belong with your doctor.
If the siding and trim around those windows are failing too, read peeling exterior lead paint; to keep sound painted casings in place instead, read encapsulation and enclosure. Every service is listed on the Grand Prairie Lead Paint Removal homepage.
