Marijuana will be big business in Portland a year from now, when the state plans to finally roll out recreational cannabis shops (you'll be able to buy limited quantities of pot from medical dispensaries in less than a month). But for entree into that market, would-be magnates are going to need to pony up some hefty costs.

As Portland City Council prepares to consider new city-specific marijuana licensing rules next week, the city's Office of Neighborhood Involvement (ONI) is floating a fee schedule that would see marijuana retailers handing the city nearly $4,000 just to get a shot at Portland customers. According to proposed fees, which ONI shared with the Mercury, pot retailers would have to pay $750 just to apply for one of the new licenses, and $3,000 if they were approved. Then they'd have to pay $3,000 a year to renew the thing.

That's by far the steepest rate the city's proposing. Operations that want to grow or process pot would pay a $500 application fee, and $2,000 for a license.

The fees are out of step with how the city regulates its liquor licensees, who pay $100 a year for applications and renewals. Here's the full schedule.

It's unclear if pot industry types will protest these fees, but expect some pushback this Wednesday. Dispensaries aren't pleased by ONI's recommendation marijuana dispensaries and retailers should only be allowed to operate from 7 am to 9 pm. The city agency stands by the hour limits.

"It will help to address any kind of nuisance acitivity in neighborhoods," says Victor Salinas, the city's marijuana program specialist.
