Ordinance No. 3971 is a municipal law of the City of Miami enacted on April 19, 1950, by Acting Mayor Robert L. Floyd and attested by City Clerk F. L. Correll (p. 364).

The ordinance mandates that land owners, operators, or authorized agents of Circuses or Carnivals must post a cash deposit before receiving a permit from the Building Division (p. 362). The minimum deposit is set at 100 for carnivals, though the Chief Building Inspector may adjust this amount based on the site area and value of public improvements (p. 363).

The primary purpose is to protect public property, such as pavements, trees, and sidewalks, from damage caused by heavy equipment and trucks, and to ensure the removal of rubbish and trash after the event (p. 362). If damage occurs or the site is not cleaned, the Chief Building Inspector may use the deposit to cover repair and cleanup costs after providing 48 hours’ notice to the permit holder (p. 363). Any unused portion of the deposit is refunded after final inspection by the Department of Public Service (p. 363).

Violations of this ordinance are punishable by fines up to $500 or imprisonment, at the discretion of the court (p. 363). The ordinance includes a separability clause and repeals conflicting laws (p. 364).

This ordinance is part of the broader regulatory framework detailed in 1935-Miami-Dade-Building-Code_p345_364.
