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.

If you plan to replace in-kind exterior windows or skylights to your residential or commercial building, learn more on how to apply online for a permit.

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.
