Capacity on a venue’s website is usually one number, and it is usually the biggest one the room can hold. The fire code does not read it that way. Under NFPA 101, as the Illinois State Fire Marshal explains it, a room becomes assembly use at 50 or more people, and the occupant load depends on how the floor is used: 15 square feet per person, net, for guests seated at dining tables, and 7 square feet for a dance floor or chairs set in rows. The same room holds roughly twice as many people for a ceremony as it does for dinner. Zola tells couples that maximum capacity is non-negotiable, and the couples who read that will ask.
So we write capacity by layout: ceremony, seated dinner, cocktail reception, and which of those can share one room on one night. It spares a couple of 180 a wasted drive to a room that seats 150 for dinner, and it gives search engines and AI assistants a specific answer to the question couples actually type.
Permits sit behind those numbers, and they change from city to city. New York City requires a Place of Assembly Certificate of Operation where 75 or more members of the public gather indoors, or 200 or more outdoors, including to eat and drink. Chicago requires a Public Place of Amusement license to rent out a facility for a party or event open to the public. It needs an occupancy placard from the Department of Buildings, runs for two years, and is not allowed within 200 feet of a church, school or hospital unless a reduction is granted. We do not advertise dates or headcounts a venue is not cleared to host.
Alcohol is the other rule that shapes the copy. A venue either holds its own license or works with licensed caterers. Texas, for one, grants the caterer’s permit only to businesses already holding a mixed beverage permit, and catered events at public facilities such as museums or community centers need a letter from the facility granting permission. Your site should say plainly which model you run, because it changes the quote and the vendor list a couple has to assemble. And if your ads mention the bar, Google’s alcohol policy applies: they must not target, or be designed to appeal mainly to, people under the legal purchase age.
