Law on Smoking Distance From a Building in California

California's legislature passed the law prohibiting smoking near public buildings because of the dangerous health effects of secondhand smoke. The law is designed to prevent secondhand smoke from entering the doors or windows of a building.

This law can only be enforced if signs that explain the smoking restrictions are posted. Locations are responsible for creating and funding their own signs.

California law also prohibits smoking inside public buildings, inside schools, within 25 feet of a playground and in vehicles with minors under the age of 18.
