2022 marks the 10th anniversary of Mayhem Mansion, San Francisco Heritage’s annual Halloween haunted-house event at the Haas-Lilienthal historic house museum. All proceeds benefit SF Heritage and support our mission to preserve the places that keep San Francisco special. SF Heritage members receive a special discount on tickets (see below for details)!

A benevolent host will gently guide you on a mysterious and informative tour through the magnificent manse, but you never know who, or what, is lurking in the dark corners and behind closed doors!

Before or after your tour, calm your nerves in our Ballroom saloon, the Spookeasy. Alcoholic (21+) and non-alcoholic beverages, as well as snacks, will be available for purchase. Don’t miss the complimentary candy cauldron!

Advance ticket purchase required. Children (9-13): $20 | Adults $30 | Group discounts available

**SF Heritage members receive $5 off the ticket price, and will be contacted starting October 1 with their unique discount code. If you are a member and didn’t receive your code, please email

In accordance with San Francisco’s current mandates, we will not require attendees to show proof of vaccination at check-in. Masks are optional.

The Haas-Lilienthal House continues to follow all city health mandates, and policies are subject to change at any time.
