Summary: A legal building site is a lot that qualifies for separate development. To qualify, the lot must have been legally separated from neighboring properties, and can’t be needed to meet code standards for a development on a neighboring lot. Since 1972, the City of Seattle has required a formal platting action, such as a short subdivision, to legally separate properties. Prior to that, property owners could create separate lots as a result of separate deeds or site descriptions on building permits.
