How to get a building permit without being a homeowner!

[Pei Lin]

Hello BiggerPockets!

I know how the title of this post may sound weird but bare with me. My parents own a property in Los Angeles, California. I've always wanted to convert the garage into an ADU, and I'm planning on clearing it out and getting a professional to design the ADU. My problem is that my parents live in Taiwan and they left me to manage the property. How can I get an ADU permit without my parents in the USA? Do I need to transfer the title of the home under my name? If so, how long will it take? Or can my parents just notarize the paperwork and get the building permit? My parents are 100% on board with this project but they're just not here.

Thank you for your time!
