is the exterior of a building, yard, carport, porch considered part of a dwelling unit and subject to a 24 hour notice to enter a dwelling unit?
There probably are no clear definitions but the logic of the notice is that it is an invasion of privacy. But going onto the porch, into the backyard [especially if there is no gate, etc. are not going into an area that the public does not have easy access to, so it would seek no notice would be needed for the landlord to lgo there. After all, why should the owner have less access then the public.
