SDCI receives many multifamily and commercial short plat and lot boundary adjustment applications proposing ten-foot-wide vehicle access easements for lots with no street frontage.  These proposals base the width of the vehicle access on the number of parking spaces. However, Seattle’s Code (SMC 23.53.025) requires vehicle access widths to be based on the number of dwelling units being served, not the number of parking spaces being provided. (Under the code, the access requirements are distinct from driveway standards, which are based in part on the number of parking spaces served.)
