Edit: Thanks for the folks that are in adjacent areas that got back to me and were kind, I was just curious as a laymen New Yorker.

UPDATE: One of my friends got back to me I guess they have blueprints and do drills and do drills and shit and that I’m not allowed to know the rest – whatever bitch tits, comments basically stated that

There’s quite a few things we do. We only have a limited area that we cover. In just about any paid department we have walk throughs that we do as a form of preplanning. Especially if it’s a high life hazard like assisted living facilities, we’ll walk through before and after it’s built to have a general idea of the layout, shelter in places, and high hazard zones.

We also have layouts of most large structures available to command that they can pull up. If we’re going in for a search or trying to reach the seat of the fire in one of these buildings, command can actually direct us in a way, and advise key features of the structure.

A lot of buildings are actually build in a very similar way, and you can tell a lot about a building just by looking at it. A lot of homes will have the master bedroom opposite the side of the house with the garage or carport in it for example. Bedrooms are generally around the bathrooms, which you can see where the ventilation is set up from the roof. Little things like that can tell us a lot.

Last point, we’re also just flat out trained to search in buildings that we don’t know the layout of. We have ways to orient ourselves and find our way out if needed, but we still need to be able to think tactically when it comes to our searches.
