House Hack ADU Tax Implications

[Jose Leanos]

Hello all,

I am wondering if anybody that has converted their garage into an ADU in CA has had any increases in their property taxes. I am reading the California real estate principles and it appears that the county assessor does have the right to raise property taxes when improvements are made.

Currently working on submitting ADU garage conversion plans for a SFR I own in Long Beach, CA and I wanted to know if my taxes would be changed in order to run my numbers correctly when calculating expenses. There will be no added square footage, just the conversion of the existing space.

Thanks in advance.
