The 10 best wedding venues in San Francisco

Rental alone covers an enormous range. A one-hour private ceremony at City Hall starts near $1,000 and a two-hour slot near $5,000, while a full evening buyout of the building runs $10,000 to $30,000. The ballrooms and historic halls sit in between — the Julia Morgan Ballroom has been quoted at $6,500 to $13,000 and the Fort Mason halls at $4,200 to $13,000, Gallery 308 being about $13,000 for a ten-hour block — and the Legion of Honor tops the list, starting at $15,000 for a four-hour rental. None of those numbers include food, and in San Francisco catering routinely exceeds the venue fee, so ask every venue whether its figure is a rental or an all-in package before comparing any two.

Yes. California requires no residency, no citizenship, no blood test and no waiting period. Both of you apply together in person at the County Clerk's office inside City Hall with government-issued photo ID; the public license is valid for 90 days, can be used anywhere in California, and needs at least one witness at the ceremony, after which your officiant returns it to the county. Check the current fee with the Clerk before you travel, as it is set locally. The ceremony you hold in San Francisco is a legally valid US marriage — you do not need to repeat it as a civil ceremony in California. Recognition at home is a separate matter: most countries will accept the California certificate once it carries an apostille from the Secretary of State, some require you to register it with your own authorities, and a few will not recognize a foreign ceremony at all unless you also complete a civil marriage at home, so confirm with your consulate before booking.

Peak-season Saturdays between May and October generally want nine to twelve months at the popular waterfront and ballroom properties, and the scarcest rooms go earlier still. City Hall works differently — civil ceremony slots open on a much shorter horizon and can sometimes be had within weeks, but private ceremony rentals and evening buyouts have their own limited calendar and go quickly. The venues tied to public institutions are the ones to approach first: the Legion of Honor and the Conservatory of Flowers can only host after closing hours, so they have far fewer usable slots per year than a hotel does.

It can genuinely change the day, and it is geographic rather than seasonal luck. The marine layer sits heaviest over the western and northern edges of the city — the Presidio, Lincoln Park, Golden Gate Park — through June and July, so a Legion of Honor lawn ceremony in midsummer may have no bridge in the background at all, while the Mission a few miles inland stays clear and warmer. Temperatures rarely climb past 70°F even in the best weeks, so plan for guests to be cold outdoors in the evening whatever the month. September and October are the safest bet for a clear, warm outdoor ceremony.
