Property tax for garage conversion in Los Angeles

[Xander Snyder]

Hi all,

I'm new to Bigger Pockets, and this is in fact my first post. So hi everyone!

I own a SFR that I live in, with a big garage that's going unused. I'm in the process of converting it into an Accessory Dwelling Unit (ADU), to rent it out as a studio apartment and get going on house hacking. I'm in the early stages, working with a designer to figure out the layout and getting quotes from contractors (so any other general thoughts on folks who have gone through a similar process in LA also very welcome).

My question is - I'm sure property taxes will increase once that becomes livable space. But how exactly does the city of Los Angeles assess that new livable space for tax purposes?
