Make Sure Your Condominium Address is Valid
SDCI is the Addressing Authority for the City of Seattle. It is essential that assigned addresses are accurate so the property can reliably receive the following services: mail delivery, utilities, and emergency services. When King County records condominiums as part of the process to assign assessor parcel numbers, they sometimes assign addresses that do not match the addresses we have on record at SDCI. This is particularly prevalent in neighborhood residential (NR) zones with attached and detached accessory dwelling units.
