Halloween boiler room at ERIA Marina
"is this the club ?" is turning a corporate event space in the Marina into a Boiler Room style party for one night. Start early, dress up, still make your Friday meeting. Mutuals listed RSVPs as closing Wednesday at 6pm, so check the page first.
RSVP on MutualsFriday, Oct 30
Cha Cha Challoween at Cha Cha Cha
A costume contest, special cocktails, Yerdrink "potions" and DJ LIVV, hosted by Adam, Lucy and Oz. Free with an RSVP, $100 without one, so RSVP.
RSVP on PartifulHaunted @ Brixton v2 at the Brixton
LUPFR Entertainment's second Halloween takeover of the Brixton: a haunted house-music dance floor, live DJs and best costume awards. Costume and ticket required.
Get ticketsLeCrew: Haunted
House and techno in the same warehouse as LeCrew's Wanted party. The dress code is costumes and they mean it: no attempted costume, no entry. About 40 of 400 spots were left on Wednesday.

Midnight Masquerade at the W San Francisco
Anthony Presents takes over the W's rooftop: masks encouraged, costumes welcome, dancing until midnight. The early one if you're doing two parties.
Get tickets on EventbriteCiaorigato Halloween party
House and afro house at the Italian-Japanese spot downtown, with Amiss, Dim The Sky, Reza b2b I Am Shlomi, and Erika Alkemiss closing. RA lists costumes as mandatory.
Get tickets on RAClub Viva x domi: After Dark at Macondray
Malki and Bozton on Polk Street. The Partiful list is full and entry is by approval, so join the waitlist and have a backup.
Join the waitlistCan you do two parties in one night?
On Saturday, yes, and it's the move. The W rooftop masquerade runs 8pm to midnight, and Ciaorigato runs 10pm to 3am about a 15 minute walk away, from 3rd St to Mason St. Leave the rooftop around 11 and you're downtown before most people are done with their first party.
Friday's three overlap, so pick the night you want:
- Free and social: Cha Cha Challoween on Haight. RSVP, or it's $100 at the door.
- A dance floor and costume awards: Haunted at the Brixton in Cow Hollow, $10 to $20.
- House and techno until 2am: LeCrew's warehouse, $49.69 at the door.
Staying north all weekend? ERIA on Chestnut (Thursday), the Brixton on Union (Friday) and Macondray on Polk (Saturday) are a short ride apart.
Before you go: notes from people who run parties
We've thrown events for more than 10,000 people. Here's what we'd tell a friend heading out this weekend.
- Screenshot your ticket or RSVP before you get in line. Service gets bad on a packed sidewalk, and the door won't wait for a QR code to load.
- Bring a physical ID and be ready to lift the mask. Most of these are 21+, and the door needs to match your face to your ID.
- "Costume required" means a real costume. At LeCrew, the Brixton and Ciaorigato, cat ears on a black outfit is a gamble. Wear something that reads from across the room.
- Buy early when there are tiers. The Brixton goes from $10 to $15 to $20, and Cha Cha Cha is $100 at the door without an RSVP.
- Check the event page the day of. Times, lineups and capacity change, and approval lists like Macondray's close.
- Pick a meetup spot and a ride home before midnight. Rideshare prices jump around 2am, and BART's last trains leave earlier than people think, so check the schedule if you're heading to the East Bay.
- Carry less. A small bag, and nothing in your costume you'd be sad to lose.
Throwing one next year? Steal these moves
Read this list as an organizer and the same few moves keep showing up:
- Free with an RSVP, expensive without one. Cha Cha Cha's $100 door price turns maybes into RSVPs, so the hosts know the headcount before the night.
- Tiered tickets. $10, then $15, then $20 at the Brixton gives people a reason to buy now and the promoter a reason to post.
- A real costume rule. Three of the seven are no costume, no entry. It makes the night feel like an event, not a regular Friday at the bar.
- Approval lists and waitlists. A full list at Macondray tells everyone it's the place to be.
- A weeknight slot. ERIA's Thursday, 6 to 10, gets the people who already have plans Friday and Saturday.
- A room that isn't a nightclub. A corporate event space, a restaurant on Haight, a hotel rooftop, an Italian-Japanese spot downtown, a cocktail bar on Polk.
The hard part is finding that room, and that's the part I do. Tell me your date and headcount and I'll find the room.
Throwing your own?
Every party on this list started with someone finding a room. If you're planning Friendsgiving, the team holiday party or a birthday, tell us the date, headcount and budget and we'll send back rooms that fit. Most SF bars and restaurants charge a food and drink minimum instead of a room fee, and December books up first.
Short notice works too: we pulled together a 250-person after-party at The Midway in a few hours.

Do I need a costume?
At three of them, yes: LeCrew, the Brixton and Ciaorigato say no costume, no entry. Everywhere else it's encouraged.
Where can I host my own Halloween or holiday party in SF?
Private rooms and buyouts at SF bars and restaurants usually run on a food and drink minimum instead of a room fee. Tell Conjunction your date, headcount and budget and we'll send options that fit.
Can you go to two Halloween parties in one night in SF?
On Saturday, yes. The W rooftop Midnight Masquerade runs 8pm to midnight and Ciaorigato runs 10pm to 3am, about a 15 minute walk away.
How far ahead should you book a venue for a Halloween party in SF?
Ideally in late summer, since the best rooms for Halloween weekend go first. Short notice can still work: we pulled together a 250-person after-party at The Midway in a few hours.
Details come from each event's page as of October 28, 2026. Plans change, so check the ticket page before you go.
