On July 1st, the Seattle City Council approved new legislation regarding the constructions of accessory dwelling units in the city.
The new law removes off-street parking requirements and also:
- Allows both attached and detached dwelling units in single-family zoning
- Introduces floor to area ratio limits in those single-family areas
- Removes the previous owner-occupancy requirements for construction
- Increases the maximum square footage from 800 to 1,000 square feet
- Adds more flexibility in maintaining existing trees
- Requires a demographic survey from future ADA/DADU owners and occupants
Here are two informative articles to learn more about these new changes to Seattle ADA/DADU regulations:
