Garage Conversion in Lancaster CA

[Lucy Caro]

Hello friends. I am an aspiring real estate investor. I just purchased my first home in Lancaster, Ca. It's a 3 bed 2 bath with a garage. I am currently living in the house and renting out two rooms. I would like to convert my garage into an ADU. Does anyone know how much is the minimum that I can realistically pay for permits, plans, materials, and labor? I would really appreciate any input.
