4. Permits and Review

Step 4 of the development review process is obtaining the proper review and permits before construction can start. For all the steps, visit the Development Process Overview. You can also start your permit process online at www.fairfaxcounty.gov/fido.


Fairfax County issues several different types of permits for construction projects: building permits, trade permits and land disturbance permits. A completed permit application is required to start the process. Applying for your permit can be done in person at 12055 Government Center Parkway, Suite 230, Fairfax, VA, or many permit types can be applied for online. 

 Fairfax Permit Q - Avoid the physical line for permits.  Get in line from home, the office or anywhere!

Drawings, plats, site-related plans and other documentation may be required. See "Review" section below for more details.


In order to determine if your project is in compliance with construction codes, the zoning ordinance and other county or state ordinances, other agency reviews may be necessary, depending on your project. Choose a review type below to learn more.
