Building an ADU in San Fernando Valley for rental income.

[Ricardo Zuniga]

Looking for some advice. I have a 3bed 1 bath with a 2 car detached garage. Located in Lake Balboa Area of the Valley. I am looking into converting the garage into an ADU and rent it out for additional income. I am considering playing the long game with this property. Bought it in 2016 and has currently appraised $150K from the time I bought it. Eventually looking into renting out the entire property and moving into a new home. Can someone assist with the process of converting the garage into a rental unit and how to go about getting the permits for it. Also what would an approximate cost be for the conversion. It will have its own entry way. Garage already has its own door entry and windows on each side with 2 solar panels on the roof. Would like to keep it simple small standing shower. Any assistance or recomendations are greatly welcomed.
