Yes, in all likelihood. Lead was widely used in both interior and exterior house paint until 1978, when new laws greatly reduced the amount of lead allowed. For example, in San Francisco, 91% of homes were built before 1978, and most have older layers of lead-containing paint. So, there is a very good chance that your apartment or rental home contains lead - at some level. As long as it is properly contained, it will be OK for your child, but when paint chips, peels, chalks or when major renovation are done, you should insist that it be taken care of immediately.
