Advice on Gate Entrance

[Tommy Cheng]

Hey all,

We're almost ready to launch our first STR/Airbnb using our ADU behind our primary house. We are thinking of having the guests enter through the side gate. This is an older wooden swing gate that has a sliding latch on the interior. There is a single handle on the outer part of the gate. Any advice on what type of lock or procedure to use for maximal efficiency and safety for guests? Should I change out the handles or the inner latch?
