AIA Document B105™–2007 is a standard form of agreement between owner and architect intended for use on a residential or small commercial project that is modest in size and brief in duration. AIA Document B105–2007 and A105™–2007, Standard Form of Agreement Between Owner and Contractor for a Residential or Small Commercial Project, comprise the Small Projects family of Document. B105–2007 is intended for use with A105–2007, which it incorporates by reference. B105 is extremely abbreviated and is formatted more informally than other AIA agreements. Although AIA Document A105 and B105 share some similarities with other AIA agreements, the Small Projects family should NOT be used with other AIA document families without careful side-by-side comparison of contents. NOTE: B155–1993 expired in 2009.
