Full Breakdown
Detroit's zoning code applies operational performance standards to every non-residential use whose noise reaches nearby R1 through R6, B1 through B6, nonindustrial PD, P1, PC, PCA, TM, PR, or SD1 through SD5 districts. Beyond the City's general noise ordinance in Chapter 16, Section 50-14-587 bars outdoor paging systems and speakers within 150 feet of residentially zoned land or a school or licensed child care center's property line, unless the equipment is a face-to-face drive-up teller window under a porte cochere. The standards exempt machinery, equipment, and facilities on-site and compliant before December 22, 1968; anything added later must comply.
Violations & Fines
Violations are enforced by the Buildings, Safety Engineering and Environmental Department; absent a specific penalty, Section 1-1-9 sets a default fine up to $500.00, up to 90 days in jail, or both, with each day a separate offense.
