First off, the Helen Hayes (the smallest Broadway house) has 597 seats).
Second, I've answered this one a few times, so pardon me if I just cut and paste an earlier response:
"The designation of "Broadway" is actually just a determination of the League of American Theatres -- a tiny little exclusive club of the people who own the current Broadway houses and co-produce the Tonys every year. While, yes, all Broadway houses have at least 500 seats, it's not as if every theatrical venue in New York city with over 500 seats (Radio City, The Beacon, The Apollo, The Delacorte) is a Broadway house.
Look at the Delacorte -- it has 1900 seats and is dedicated solely to the production of professional legitimate theatre ...... but it's ONLY not considered a Broadway house because the League says it's not a Broadway house (and they principally don't include the Delacorte because it's purely not-for-profit and subsidized by the state and corporate donors -- the only people who get to be in their "Broadway" club are those who take the same sorts of finanicial risks that they do) .
THEY decide who gets to join their club and who doesn't, based on their own whims. 20 years ago, Porgy and Bess played at Radio City. Because it was an expensive for-profit venture (and some of their producer buddies were co-producing it), guess what? Radio City Music Hall became a Broadway, Tony-eligible house for that production (and that production only). The League does whatever they wants and makes all the rules and decisions which are in their best interest -- basically they can designate any theatre in NYC a Broadway house if they want to ...... as long as the owner (and the producers of the shows playing there) are willing to pay the price.
Additionally, certain specific contracts are negotiated with each Broadway theatre by each union (Equity, Local One, Local 802 etc.....).
Off-Broadway is sort of the default category for all those theatres that aren't deemed Broadway theatres. Most have 100 to 499 seats, but then BAM has two theatres (each with 1000+ seats), which are also considered off-Broadway. These theatres all also have contracts with the major theatrical unions, with minimums determined by the number of seats.
Off-Off-Broadway generally denotes theatres with fewer than 100 seats (there are hundreds of them in town, often called "black box theatres") as well as other venues which aren't exclusively dedicated to theatrical production (churches, outdoor spaces etc). The main thing that makes a theatre "Off-Off-Broadway" is the fact that it has no specific contracts with the major unions (though Equity showcase rules do apply).
