Housing here
1,537,034 housing units in Los Angeles city, California, of which 71% were built before 1980 and 19% before 1940. 64% of occupied homes are rented.
Why this is on the page: older housing has had longer to accumulate water events, and its plumbing and building envelope are closer to end of life — so age is a reasonable proxy for how often local firms meet older construction, not a statement about any individual property. It does not mean older homes have mold. With 64% of homes rented, a large share of water and mold problems here are a landlord repair duty before they are a contractor decision.
