Co-op bylaws

Hi, I am interested in purchasing a unit in your building but wanted to see if some of the residents/shareholders could help clarify few things:

1) Is the building mandated for 100% owner occupancy?
2) Is there a mandate for minimum down payment on the unit?
3) Is there an agreement with a local garage for parking? Said differently, are you guaranteed a spot if you purchase a unit in the building or do you have to be on a standby list. I previously lived relatively close to Aquitania (on Margate) and parking at night was a nightmare.
4) It seems to me assesments are relatively high even for an 80 year old building (almost 50% more then i expected). Is this a result of a recent special/reserve assesment or has this been a case for a while now?
5) What percentage of the advertised unit square footage is common space? For example, if the unit is 1000 sqft I usually expect about 10-15% of that to qualify as common space (building lobby, hallways etc), and measured (actual) square footage of the unit itself to be 850-900 sqft - is this the case at Aquitania as well?
6) Is it possible to get a copy of building bylaws and eligibility requirements for joining the co-op?

Thank you for any kind help and for creating this very useful website. You have a lovely building.

Regards,
Ivan
