Lot Coverage Exceptions (23.44.010D)
If any of your lot lines abut a dedicated alley, you may add half the area of the alley to your total lot area, up to a maximum of 10 percent of your lot area, when computing lot coverage. Certain structures are not counted in lot coverage.
These include:
- Pedestrian access bridges that are 5 feet wide or less (uncovered and unenclosed).
- Barrier-free access ramps or other access for the disabled or elderly meeting Washington State Building Code Chapter 11
- Decks or parts of decks which are not over 36 inches above the existing grade.
- Freestanding structures such as fences, bulkheads and freestanding walls, but not arbors.
- Underground structures or the underground portion of a structure.
