How can I convince my mom to..? Options

How can I convince my mom to let me move out to the apartment in our backyard? We have this apartment in the backyard, it's above the garage, and it has a small kitchen, a living room/bedroom as one room, and a bathroom with a sink, toilet and a tub. It would be amazingly cool to live out there. But, my mom's only thing is that it's just us two and the dog living in our house now, and she just is afraid to sleep alone in the house at night because she's paranoid about burglars and stuff. How can I convince her that she's fine, and I'll be fine? I'm almost an adult, too. And pretty soon, I'll be moving out anyway.
