Frequently Asked Questions

When does party noise become illegal in Redwood City?
When a gathering of three or more people generates noise more than 6 dB above the local ambient level between 8:00 p.m. and 8:00 a.m., measured either outside the property in a residential district or 3 feet inside a wall with windows and doors closed, under Sec. 24.20.
Can a party host be personally billed for police costs in Redwood City?
Yes. Under Sec. 24.22, once an Enforcement Officer has given written warning and the excessive noise continues within 12 hours, the host, or the parents of a minor host, become jointly and severally liable for police response, arrest and court-appearance costs, plus collection costs capped at $15,000.00.
Does Redwood City warn before citing a loud party?
Yes. Sec. 24.22 requires the Enforcement Officer to serve written notice to the property owner and the people allowing the gathering before cost liability attaches; only if the excessive noise continues after that notice does the liability and citation exposure under Sec. 24.21 kick in.
