For cannabis retailers
The Office of Cannabis is working with existing cannabis businesses to authorize adult-use cannabis business activity, including sales.
Required handout for existing retailers

All cannabis retailers selling adult-use cannabis must make the Safe Consumption of Cannabis Products handout available for customers.
Existing MCDs that receive authorization for adult-use sales will be required to comply with all of the requirements and prohibitions imposed on cannabis retailers under Article 16 of the Police Code (98 pages).
Permit and licensing fees
We’re still working out the fees for permits for cannabis businesses in San Francisco. California licensing fees are on the California Cannabis Portal.
