Get one of these:
Although it will probably set you back a few grand...
that thing is pretty dope actually!
FYI... ADA requires handicapped access via elevator but not all buildings are required to comply with ADA... Only "public" buildings. Private venues, clubs, halls are not always required to be ADA... Especially if they are old or historical.
I'm actually headed to a venue in a few minutes where I sold a wedding on Boathouse Row in Philly and I have to drag equipment up to the second floor. The first thing I told this client was "I'm not bringing the big sub"... The LS801 says home and I'll bring a KSub.
I'm going to have to take back what I said earlier, because I did have a Yacht Club gig on a floating clubhouse a few years ago where there was not only stairs, but practically everything else you can think of to make load in and out a nightmare.
I do this for a living and have a variety of subs - 15", 18", and 21" so I can really handle just about anything. But since ADA that's the only job I can remember out of hundreds of rooms that I couldn't just roll in.
I guess it's just a matter of knowing what you're going to be doing in your area. There was another guy in another forum who recently put up his nightmare gig - setting up on the other side of a freshly sodded 100' lawn upon which no vehicles or hand trucks were allowed to pass over. It all had to be brought in by hand.
2 story buildings are not required to have an elevator or escalator. I know dis cuz i was in da hotel biz for many a year. But um... man... I just don't know. You better get you a 23 wheel dolly and 43 strong muscular men (or women )
