Comment:
Under subdivision (a), service must be made both by first class mail and delivery for service in the manner prescribed. It is expected that the officer serving the complaint will exercise due diligence when attempting personal service upon the tenant. This may be demonstrated by, among other things, attempting service at varying times of day, making a reasonable number of knocks upon the tenant's door, knocking at all available doors of the premises, or announcing the officer's presence. Posting is required in all cases to facilitate notice to an occupant of the property.
In actions where wage garnishment may be sought under Pa.R.Civ.P. 3311, the landlord may authorize the sheriff or constable to make personal service upon the tenant. The landlord may authorize the sheriff or constable to make additional attempts to effectuate personal service upon the tenant so the landlord can later prove such service if attempting to garnish wages under Pa.R.Civ.P. 3311. Additional service attempts by the sheriff or constable may result in additional fees.
