Seattle Zoning Ordinances

[Keyana Buckner]

Can anyone give me some good material to reference when it comes to zoning ordinances in Seattle(King County)?

For Example: What does "Zoned LR1" mean? 

Also curious because Im buying my first property to house hack and I want to be sure I know what I can and can't do on the land as far as Accessory Dwelling Units go.

LR1 is Lowrise 1 -  low density multifamily.   The rules have changed a bit since I became familar with them,  but it used to mean one unit per 1600sf of lot space with height and lot coverage / floor area ratio limits.   Now IIRC there is no unit count limit,  but the height and lot coverage ratio still apply.   A bunch of other factors impact the rules as well like urban village overlay,  proximity to transit,  and MHA fee zone.

Seattle's website has all this info:
