Is an Individual Owner Required?

Re: A letter describing a Special Assessment to "repipe the ENTIRE (my caps) building" was mailed to the owners of the Condo where I live. The majority of owners who voted approved the assessment.
I now find that I am going to have to also replace the pipes in my unit (under the sinks).
As required by law the assessment was described-the total amount of the assessment, the length of the assessment, the total amount to each owner. There was nothing in the letter that informed me that I would have to pay an additional sum to have my pipes replaced.
Because the letter stated that the money was used to re-pipe the ENTIRE building and did not specify only the common area and, inasmuch as there was no mention of any additional costs to me, the individual unit owner, I am wondering if I must replace the pipes under my sink.
Shouldn't the assessment letter have stated that there "could" be an additional charge to me for replacement of pipes within the individual unit?

context is everything, and i suspect most judges would not see the "contract" the same as you Jean. They would assume a contextual basis for the word "entire" based upon the previously established relationship, which is spelled out in your by-laws, codes, covenants, etc.. I doubt they would impose a legal obligation on the HOA for use of the word "entire" in their letter of notice to you, since they would feel it would refer to their previous contractual obligations, and not refer to a new contract agreement with you.
