Quick Permits

Quick permits are trade-specific permits that can be issued without the need for a plan review. Structural work CANNOT be permitted as a quick permit.

Individual landmarks/historic districts

Roof permits and any other quick permits involving exterior work on an individual landmark or within a historic district cannot be issued online via e-permits. For these locations, submit via email after receiving approval from Landmark Preservation.

How to apply

For minor work requiring quick permits but introducing little to no visible change to a historic structure or property:

Quick review approvals may be issued by Landmark Preservation for the following existing exterior features providing that the applicable design guidelines and standards are met:

  • Rear-yard decks and porches (must demonstrate no change in size, height, materials and ornament)
  • Rear-yard fences (no change in height, openness, and materials)
  • 1-2 flat profile skylights on rear- or side-facing roofs
  • Sheds not on foundations (less than 100 square feet)
  • Exterior HVAC work (no change in geometry, demand, or materials)
  • Simple exterior electrical or mechanical work that is not visible from the public street
  • Reroofing (no change in materials, color, or installation pattern)

For more significant alterations, visit the Landmark Design Review webpage for guidelines and instructions on how to apply.
