What's the biggest building you've seen on a .18 acre lot in the U.S.? I'm thinking multifamily, in terms of units and stories.

[{"id": "fw66kih", "text": "This is entirely dependent on the local zoning along with a myriad of other factors. In philly for instance, CMX4 is the second highest level of zoning for commercial mixed use properties and it allows for up to 700% FAR with bonuses and 100% occupied area. So on a 7,840SF lot, you could build a 54,880SF building. Roughly speaking that means that it would be a 7 story building because the footprint is 100% of the lot and then the max occupied area is just 7x that.\n\nCan you provide some other info about why specifically you\u2019re asking?", "replies": [{"id": "fw6ejjw", "text": "King_fish is right. In many places you might tap out at 1x the land area but in NyC that do 50x. Zoning laws control the limits. Building costs typically determine if the deal makes sense.
