Check out City of Oakland Muni Code Chapter 8.28 details exactly what the rules are. Getting code enforcement to do something- enough said on that. Pain looking this information up and letting the tenet or landlord know what rules are is a good first step I have done it. Pro-Bono public works, Code Enforcement ect. The City can back bill for service from when they started the business.

Shameful!

Why is the city of oakland not acting in this violation?
