Legal Question in Landlord & Tenant Law in California

Not necessarily. Depending on the reason it is uninhabitable the landlord will generally have time to effect repairs. This is sometimes called "yellow tagged" as opposed to "red tagged." If it is possible to repair the premises then most leases and rental agreements have provisions for how damage to the premises and repairs are handled. Generally if the property can be repaired in a reasonable time, only rent rebate for those days are owed, although by your zip code you may have additional rights under the L.A. rent ordinances. If the property cannot be repaired and/or the landlord fails to repair, then the owner does have to remove it from the market and the tenants are entitled to relocation assistance. Again, L.A. local law may give greater rights.
