Do I need a permit for window or exterior door replacement in San Antonio?
It depends. Whether window or exterior door replacement needs a permit in San Antonio comes down to the details of your project.
Straight like-for-like window and door replacements are exempt in some Texas cities (Austin, for example, exempts garage door replacements), but enlarging an opening, changing egress, or altering structure typically triggers a permit and a framing inspection. Requirements vary by city and are set locally under Texas Local Government Code Ch. 214, not by the state. Confirm the exact rules with your local building department. San Antonio's No Permit Required List exempts replacing an existing door and repairing a window by replacing broken glass only; installing new windows or altering an opening is treated as work on windows, doors, and walls that does need a permit. Adding or removing a structural wall around an opening requires a third-party engineering report and inspection, per the DSD Home Remodeling FAQ. In a Historic, Neighborhood Conservation, or Corridor District, the design and materials of windows and doors may be restricted and can require Office of Historic Preservation review even when a building permit would not otherwise apply. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule.
