Seattle DCI has recently clarified its interpretation of the Seattle Residential Code (SRC) requirements for accessory dwelling units (ADUs). (ADUs are separate living spaces within a house.). Our code requirements are different, depending on whether the ADU is in a new construction project, or it is a remodel of an existing space within a single-family residence.
Not all construction and demolition waste needs to end up in a landfill. In fact, much of that material can be recycled and even reused. With thoughtful consideration, developing a plan for how each material can be managed prior to the start of a project will help to ensure materials are handled in the most sustainable way. Therefore, new requirements for both the 2012 Seattle Building and Residential Codes ask that a Waste Diversion Plan is submitted with your application for all projects greater than 750 square feet. The plan should identify assumed waste materials, the hauler, and the receiving location for each material.
The draft Seattle Residential Code is available for public comment. DPD expects the 2012 Seattle Residential Code to take effect next summer or fall along with the other 2012 technical codes. The draft contains only the portions of the code for which amendments are being proposed.
