Frequently Asked Questions

Can a contractor work at night near my house in Rohnert Park?
Not without a permit. Section 9.44.120 bars construction and repair noise within a residential zone, or within 500 feet of one, between 6 p.m. and 8 a.m. unless the contractor has first obtained a permit from the city's superintendent of public works.
What equipment counts under the construction-hours rule?
The section names pile drivers, power shovels, pneumatic hammers, derricks, and power hoists specifically, then adds "any other construction type device," so the after-hours restriction is not limited to that list.
Is there an exception for emergency repairs?
Yes. Section 9.44.120 exempts "emergency work," which § 9.44.020 defines as work needed to restore property after a calamity, protect people or property from imminent danger, or restore utility service, so utility crews and emergency contractors do not need a nighttime permit.
