AIA Document B109–2020 is a standard form of agreement between owner and architect for building design and construction contract administration for a multi-family residential or mixed-use residential project. B109–2020 contains terms and conditions that are unique to these types of projects. B109–2020 is based on AIA Document B103™–2017, Standard Form of Agreement Between Owner and Architect for a Large or Complex Project. AIA Document B109–2020 uses the traditional division of services into Basic and Additional Services but adds a Pre-Design Services article that includes items such as assessment of project feasibility, layout, and regulatory.
B109–2020 is not intended for use on residential projects that will include a residential condominium unless specifically set forth in the initial information. Otherwise, B109–2020 includes a representation by the Owner that the project will not include a residential condominium. If B109–2020 is used for residential condominium projects, users should review and consider modifications. AIA Document B509™–2020, Guide for Supplementary Conditions to AIA Document B109–2020, includes a discussion of potential risks that may be inherent in residential condominium construction and offers model language for inclusion in B109–2020 to better allocate these risks.
