Giving yard work notification?

[Chris Stromdahl]

I plan on maintaining the landscape of my rental properties, at least in the beginning.

As a courtesy, I intend of giving the tenants prior notice with my planned arrival date/time, but is it required by law that I do this?

I understand that I need to provide them with prior notice if I intend on entering the living spaces, but does the same hold true for the yard area?

The property is in Pierce County, Washington.

Thanks, Chris
