Overnight parking is generally permitted on public streets in San Diego, but it is governed by a strict 72-hour limit, after which a vehicle must be moved or face a fine of approximately $53.50. However, many specific districts have more restrictive rules; for example, many areas in La Jolla and Ocean Beach prohibit oversized vehicles or trailers from parking between 2:00 AM and 6:00 AM without a permit. In downtown "Hospitality Zones," meters are enforced until 8:00 PM, but you can leave your car overnight once the meter expires, provided you move it before enforcement begins at 8:00 AM the next morning. In 2026, San Diego has also expanded "tiered" pricing for city-managed lots, particularly near Balboa Park and the Zoo, where overnight rates can be significantly higher than street parking. Always check the curb color and posted signage: red means no stopping at any time, while white and yellow zones have specific loading windows that may be enforced 24/7 or only during business hours.
