they do inspections once a year for the smoke detectors, sprinklers n shit... they also come everyonce in a while to change the filter of the A/C.
2000 watts is kinda big for an apartment, if you're gonna be in a fiercly conservative area, ie Texas, Kentucky, Alabama, etc. think twice about it, judges don't care much for 'narcotics' and will sign warrants for shit....
while you might be able to get off because of technicalities, they can still seize you're property because of the loose definition of paraphernalia.
the wise choice would be to use CFL's. or maybe 1 or 2 150 watt HPS's.
big bulbs need big fans, fans make noise, and sleeping with a lot of noise is a bitch.
think about all of that, and remember that setting shit up is easy in brainstorm stage, when it's time to build, it's a different story, you need to keep it within you're skill set, within you're price range, and keep it smart.
a 2000 watt grow in an apartment seems dumb to me. totally doable, not too smart though...
