Is the documentation manageable or are there so many Rules you need a lawyer to interpret them?
Your contract should provide for your entitlement to the documents that govern the property you are buying: the "decs" or Declaration of Condominium, the Rules, the Bylaws, the minutes and the budget. Those should be provided within 1 - 5 days of your offer. You should also provide in your contract (or in attorney review) that the contract is CONTINGENT ON APPROVAL OF ALL CONDO DOCUMENTS. Make sure you read through the documents. If you are not satisfied with the Rules (e.g. you can only have one pet and you already own two), the way the Board is run (decisions are made in the backyard instead of at real meetings with recorded minutes) consider whether this is really the place for you. You should look for the issues that would cause fines to arise. If it feels like you are joining a corporation, instead of locating a home, you may want to consider an alternative residence.
How are common areas addressed?
One of the advantages of a unit in a large condominium association, is that there are people to handle maintenance and security. But being part of such a large community generally comes with many rules to make it a comfortable living space for all - or most. You should consider whether the people in the building tend to be like-minded - for instance - is the need for a high level health club important to most of the people in the building? if so, it is likely it will be maintained and well-managed. Are there children in the building? Is the population older? The rules that are established will vary according to the personality of the unit holders - and the board - if the community is exceedingly divergent.
