Affidavit of Owner - Occupancy

in either the principal dwelling unit or the accessory dwelling unit and the property owner must comply with the
general requirements for Accessory Dwelling Units as specified in the Kirkland Zoning Code. In other words, the
property must be owner-occupied.
“Owner-occupied” means the primary and permanent dwelling place of a person who has an ownership interest in it.
This person lives in such dwelling despite temporary absences, intends it to be his or her legal residence, and intends to
return despite temporary stays elsewhere.
I hereby acknowledge compliance with the owner-occupancy provisions of the Kirkland Zoning Code
, and with all other
general requirements for Accessory Dwelling Units as specified in the Kirkland Zoning Code.
I certify (or declare) under penalty of perjury under the laws of the State of Washington that the above answers are true
and complete to the best of my knowledge. I understand that the lead agency is relying on them to make its decision.
