Full Breakdown
Hanford Municipal Code § 9.10.070(H) carves out a narrow exemption: noise from generators required for medical purposes or during power outages is excused from Chapter 9.10's noise rules. Any other generator noise, for example, running one for a backyard party or ongoing convenience, gets no special pass and is instead measured against the general unreasonable-noise prohibition in § 9.10.050 and the per se prohibited-noise list in § 9.10.060. Enforcement runs through the city manager and police chief.
Violations & Fines
Non-exempt generator noise that violates § 9.10.050 is a misdemeanor under § 9.10.090, punishable by up to a $1,000 fine and/or six months in County Jail, with each day of continuing violation counted separately.
