DBI approves window infill permit amid ongoing litigation at 3621 De Visidero

The San Francisco City Council meeting on July 4, 2025, focused on a contentious building permit issue involving a property line window at 3621 De Visidero Street. The discussion centered around the permit issued by the Department of Building Inspection (DBI) that allowed for the infilling of a fire-rated window, which has drawn objections from the neighboring property owner at 3627 De Visidero.

The permit was granted to address a Notice of Violation (NOV) related to the window, which is a sealed steel frame that does not open. The work was completed without requiring access from the neighbor, in compliance with a court-ordered restraining order that prohibits communication between the parties involved. The owner of 3627 De Visidero expressed concerns about potential water intrusion and the adequacy of waterproofing, arguing for the complete removal of the window rather than just infilling it.

DBI representatives defended the permit, stating that the infill meets fire safety requirements and that the existing window frame serves primarily as a weatherproofing measure. They acknowledged the aesthetic concerns raised by the neighbor but emphasized that the current solution is legally compliant and addresses safety regulations.

The planning department noted that the property is a potential historic resource and clarified that the July permit did not trigger a review since it involved retaining the window rather than removing it. The discussion also touched on the broader implications of property line windows, including privacy and fire safety concerns, with DBI officials explaining that while the window may appear unsightly, it fulfills necessary building codes.

In conclusion, the council's deliberations highlighted the complexities of building regulations in residential areas, particularly when neighborly disputes and safety codes intersect. The outcome of the appeal remains uncertain, pending further discussions and potential resolutions between the involved parties.
