Full Breakdown
San Jose Municipal Code § 20.100.450 sets the citywide construction-hours limit for sites within 500 feet of a residential unit: no construction activity before 7:00 a.m. or after 7:00 p.m. Monday through Friday, and none at all on Saturday or Sunday, unless a development permit or other planning approval expressly allows different hours. The rule applies whenever a development permit or other planning approval is required for the construction activity, per subsection C, and it works alongside any hour limits already written into that specific permit. City planning staff enforce it through the development permit process, not as a standalone noise citation.
Violations & Fines
Construction outside the allowed hours near a home breaches the site's development permit; the city can pursue code enforcement and can revoke or suspend the permit under Chapter 20.100's order-to-show-cause process.
