Summary
Unincorporated Santa Clara County requires a special event permit from the Director of Roads and Airports before any block party closes or restricts use of a county road, filed at least 15 days ahead.
Any person intending to conduct, organize, or set up a major or minor special event or block party on a road shall first obtain a special event permit from the Director. ... If the event is a festive gathering, which is stationary in nature and is usually characterized by a single neighborhood congregating to celebrate, and requires the closure of a road or otherwise restricts the general public use of the road then the procedures for obtaining a Special Event Permit for a block party shall be followed.

Full Breakdown
Sec. B3-147 requires anyone planning a block party, a festive gathering that closes a road or restricts public use of the right-of-way, to get a special event permit from the Director of Roads and Airports before the event. Block party applications must be filed at least 15 calendar days ahead under Sec. B3-149(b)(3), and the Director must approve, conditionally approve, or deny the permit within seven calendar days. The rule covers roads in unincorporated Santa Clara County only; a block party inside San Jose, Sunnyvale, or any of the county's other fourteen cities is permitted by that city, not the county.
Violations & Fines
Holding a block party on a county road without a permit is unlawful under Sec. B3-158(a) and subject to an administrative fine under Division A37 of the Ordinance Code.
