The majority of W-2 workers that own rental property in California generally will not benefit from depreciation deductions (losses on rental properties). I won’t go into all the specifics, but unless you are a full time real estate professional you won’t be able to offset ordinary income with passive rental losses. There is an exception to this rule based on income limitations — however, those that own rentals in SoCal or the Bay Area are likely making too much money to realize the benefit.
