GWW> Thanks, GWW> Garth It is likely to be a building code thing (depending when and where it was built), but the following has been in the IBC and BOCA (at least) for along time: "503.1.2 Buildings on same lot. Two or more buildings on the same lot shall be regulated as separate buildings or shall be considered as portions of one building if the height of each building and the aggregate area of buildings are within the limitations of Table 503 as modified by Sections 504 and 506. The provisions of this code applicable to the aggregate building shall be applicable to each building." The operative word is "lot". If the buildings are not the same lot, regardless of addresses and meet the other code criteria, it can be considered one building. -- Best regards, Dan Kaczor, Plans Examiner (but not a Guru to anyone) [EMAIL PROTECTED] _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
