Window Replacement Project

Follow this step-by-step guide to help you understand how to get a building permit to replace your existing windows.

Step 1: Check if the property is historic

Visit the Property Information Map

  • Begin typing an address in the search field at the top of the page – a list of pre-existing properties may appear to choose from, or you can continue entering the address – another option is to click a target location on the map below the search field.
  • After results appear, select "Historic Preservation" from the column on the left – the property will be categorized as A, A*, B, or C – to learn what these categories mean, see Standards & Recommendations for Window Replacement Appendix - Historic Designations.
  • If the property is Category A* (a City Landmark or in a Conservation District), you are not eligible for an over-the-counter approval. Instead, you may need to apply for an Administrative Certificate of Appropriateness or a Minor Permit to Alter. 

If you have questions, talk to a Preservation Planner at the Permit Center, SF Planning Counter or email pic@sfgov.org.

Step 2: Fill out the building permit form

Complete the Over-the-Counter building permit form, also known as Form 8 (the pink form).

If you want to expand an existing window or add a new window to the exterior of your building, you must include building plans and elevations with your Over-the-Counter (OTC) building permit application – see Submittal Guidelines for building plan requirements.

Step 3: Describe window replacement on Form 8

In this step, you need to explain your window replacement project on Form 8. Include these details:

  • How many windows you are replacing
  • Where the windows are located (for example, front of the building, side, or back)
  • What the new windows will be made of (wood, aluminum, steel, vinyl, etc.) and how they work (for example, sliding, double-hung, or fixed)

Here’s an example of what to write:  “Replacement of two windows on the second floor of the street façade with two new double-hung wood-sash windows.” 

It helps if you bring specific information about the new windows, such as a product sheet. You can get this from a window supplier or contractor. This can help City agencies review your project.

Step 4: Submit to the Permit Center

After you finish your application, you need to bring the application and materials to the Permit Center.

At the Permit Center, you will visit different stations, including:

  1. Permit Center Help Desk – They will help you get the forms and fill them out if you need help.
  2. Central Permit Bureau (CPB) – They will give you a building permit number, check if your application is complete, and send it to the right City agencies to review.
  3. San Francisco Planning Department Counter – They will check your window replacement to make sure it follows the Planning Code.
  4. San Francisco Department of Building Inspection (DBI) – They will check your project to make sure it follows the Building Code.

If a City agency has questions or needs more information, you may have to provide more documents.
