Sign Code Design Standards

1. Overview

Regardless of whether or not a sign requires a permit, signs must comply with all associated regulations. Compliance shall be determined based on Florida Building Code, City Code, and Miami 21 Zoning Code including:

  • Size and area (Aggregate Area Calculation)
  • Location standards
  • Sign placement
  • Illumination regulations

You can view detailed information on the sign design standards by accessing Table 15 of the Miami 21 Zoning Code. Table 15 is located in Section 10.2 and illustrates in detail the sign design standards by sign types allowed within specific Transect Zones for signs requiring a permit. 

You can use the Zoning Interactive Tool to find out which Transect Zone your establishment is located in.

4. Sign Area 

The sign area includes a regular geometric shape, or combination of regular geometric shapes which form or approximate the perimeter of all elements in the display surface. The total sign area allowed can be determined by using the aggregate area calculation formula. 
Aggregate Area = (total linear frontage) X (Aggregate area ration) 

Monument Sign Area 

  • Monument signs may include up to two (2) display surfaces. 
  • The base of the sign structure is not considered into the display surface calculation.
