Outdoor Music

Detroit Code §36-1-2 restricts fixed outdoor speakers.

Construction Hours

Detroit Code Chapter 36 sets no clock-based construction-hour window. Construction is regulated only by the general reasonableness standard of §36-1-1(a). Site-specific construction-hour conditions are imposed through BSEED permit conditions rather than the Code itself.

Detroit is more permissive than most cities when it comes to construction hours. That said, there are still limits.

Amplified Music & Events

Amplified music is regulated by §36-1-1(a) (general reasonableness) and §36-1-1(b) (motor-vehicle audio audible past ten feet). Fixed outdoor speakers are separately restricted by §36-1-2. Permitted parades and public gatherings under §40-1-25 or §50-9-16 are exempt.

Leaf Blower Rules

Detroit Code Chapter 36 contains no leaf-blower or lawn-equipment ordinance. Gas and electric leaf blowers are governed only by the general reasonableness standard in §36-1-1(a). Detroit has no gas-blower ban and no fixed time-of-day window for leaf blowers.

A §36-1-1(a) violation is a misdemeanor under §36-1-6(a), punishable by up to $500 and 90 days in jail. Continuing violations may be cited each day they occur.

The rules around leaf blower rules in Detroit lean permissive, but that does not mean anything goes.
