Always have you or your representative there as well for two reasons.1) To protect your tenants belongings and privacy (There is no reason for a kitchensink repair to go into their bedroom etc)2) To prevent "Scope creep" with an issue.

You want a tenant who will respect your sister, her privacy, understanding her kids will be alone at times and is willing to protect them or look after them without having to be there right next to them.

Gotta use the corner of the garage for privacy because the neighbors love to watch!

I was told there was a report however by privacy laws not much info could be released other then one family member was the last to see them. 

You also need to look at what you are getting privacy from.

Home owner had bought the surrounding land for privacy many many years ago.

Well thank you all for your replys rude or not.but yes I am moving on and he have lived at the residence for 7 years and paid my rent on time every month.im not going to explain anymore but yes in the state of California the landlord can' not enter your property or residence unless it is a emergency and with a 24 hour or 48 hour notice he or she can not enter without your permission.and for them to break my locks and go into my garage taking pictures and pushing on my door making threats that he's gonna break it down or go threw my windows that's not right.thats breaking and entering and breach of quit enjoyment along with alot of other rules he had broke.it don't matter if he owns the place or not that's also invasion of privacy and another charge could be home invasion.also he entered the day after he said he was within the 24 or 48 hour notice so he should have givin me another notice to enter.just because a tenant holds rent or goes threw a eviction does not mean they don't deserve to be respected as people.landlords or owners think they can do what they want because they own the place.well they can't they gotta follow rules just like everyone else.renting out your property is just like the tenant has ownership of it untill either the tenant releases it back to the owner or the judge untill then they have no right to force entry or bring a lock smith to open your doors.when you rent out propertys comes issues at times and always should be prepared.landlords should be aware of the tenants rights.also they should be aware if a tenant gets hurt on the property or there guest the landlord is responsible for that and suppose make sure property is safe at all times.so I got a bullet in my door and went threw the hall to my bathroom and my 14 year old son was home alone thank God he was ok but that's a security issue with the neighbor Hood hoodlums.and they say I gotta replace the door.nope.i got so much to say were tenants need to fight for there rights and stand there ground because alot of landlords are bully's and are unfair.they can be the nicest to your face and evil behind your back.and for your landlords to be telling your neighbors your situation and making fun of your mental state and your financial situation and your means of living is not right.i believe that is slander and due to all that causes emotional and physical distress.so maybe people should takes some notes.there wrong not right to enter if it's not a emergency.i stand by my beliefs

The problem is the larger the ADU the more people you'll have close by.Dylan's right about separation too; build a wall etc for maximum privacy.
