This document analyzes safe harbor laws for commercially sexually exploited children and provides recommendations for San Francisco. It finds that over 100,000 children in the US are victims of sex trafficking each year, and the San Francisco Bay Area is one of 13 areas with high rates. Existing laws treat these children as criminals, so states have implemented safe harbor laws to decriminalize youth prostitution and provide services. The document profiles 4 jurisdictions' laws, finding elements transferable to San Francisco. It recommends San Francisco update codes to decriminalize underage prostitution and implement coordinated services, training, data collection and funding for a safe harbor program.
