This type of service can only be done for 30/90-Day notices, not 3-Day notices. Then it depends on if the tenant signed for the notice himself or herself. If this is how you want to serve, or did serve, make sure you checked the box that said someone had to sign for the notice when you filled out the certified mail form. Also remember that the post office will attempt up to three times to deliver the notice before returning it to you, this can take up to 15 or more days for the procedure, and if it is returned as unclaimed, you have just lost those 15 days. If it’s signed by the tenant, it can be argued to be a personal service. If its signed by someone else other than the tenant-this is a little harder to prove as a substitute service because of age factors and such so it would be wise to try and personally serve the notice or posting of the property. If the notice comes back as never been received, definitely go and serve the notice by either personal, substitute, or posting and first class U.S. mail-Refer to section on Service
