Can my landlord come in without asking in WA?

Not without written notice, except in an emergency. Inspections need 7 days' notice, 4 a year at most.

If a time does not suit, they must try to agree another. Advertising photos need your permission.

What to send

I think your notice for [date] does not meet section 46. Please send a valid notice with the day and a time that suits me.
