To exempt exposing building faces and projections from exposing building faces of certain dwelling units facing detached garages or accessory buildings and of certain detached garages or accessory buildings facing a dwelling unit from the requirements of Sentences 9.10.15.5.(1) to (3), which would otherwise require certain limiting distances, on the basis that detached garages and accessory buildings are considered an integral part of a dwelling unit, and such structures are generally very small and the incidence of fires in such structures in relation to house fires is low. There is insufficient risk, therefore, to require the spatial separation of a house from its garage or carport.
