Getting ripped off for fire alarm work!?

Is it okay for my next door neighbor to run a private business out of their unit?

Our building is reaching the 40 yr recertification deadline and the current board members fear that any critical findings will result in significant costs.

Board of directors is attempting to spend $200,000. They are trying to do this under maintenance to avoid a unit owner vote. Is this a capital expenditure?

Is it required that the association provide us with a working doorbell system. Is it legal for them to just leave the doorbell system non-functional?

Has anyone seen any specific rules banning the use of fireworks within a condo complex, especially in areas where they are legal?
