Before there was an eviction moratorium in some locations local law already required notice if the owner wants to sell or move into the rental property. For example, Seattle and Burien require 90 days. Federal Way requires 120 days.
In Seattle and Burien, the landlord therefore must give 90 days notice(not 60 days’ notice).
In Federal Way, the landlord must give 120 days’ notice(not 60 days’ notice).
Also, the termination date must be the last day of a rental period (usually calendar months), not 90 or 120 days from the current date.
