California legislators passed a law allowing smoking bans in multifamily housing complexes.

"I think what this does is provide legal clarity putting [landlords] on solid legal ground if they choose to have those restrictions," said Craig Powell, whose Sacramento company Powell Properties LP owns several upscale apartment complexes.

The law, that went into effect Sunday, requires landlords to specify in their lease/rental agreements where smoking is prohibited on their properties, The Sacramento (Calif.) Bee reported.

State Sen. Alex Padilla, D-Los Angeles, authored the bill signed into law by Gov. Jerry Brown Sept. 6.
