What We Do

Development Support and Environmental Management (DSEM) is a group of divisions and programs within Leon County which provide one-stop permitting, review and approval of land development activities.  The primary mission of DSEM is to ensure the continued vitality of the County, including both the built and natural environments, by promoting awareness and compliance with the Board's adopted growth management regulations.

DSEM's offices are located on the second floor of the Renaissance Center at 435 N. Macomb Street.  For general information, or if you are unsure which division you need to contact with your questions, please click the "citizens connect" button above.   

 

Electronic Application Submittal Process (ProjectDox)

Leon County accepts and reviews applications electronically through ProjectDox, an electronic plan review program. Electronic submissions for a building permit application, site and development plan application or an environmental management permit application are accepted, but may have requisite requirements.
