Buying a Triplex in Raleigh, NC . Can I rent all units on Airbnb

[Romeo Alcid]

I'm thinking of buying a triplex in Raleigh to Airbnb the units but I came across the regulations website and I'm seeing this statement there:

1. For any multi-unit living use, no more than 25 percent, or two dwelling units, whichever is greater, may be used for short-term rental in any single building.

Does this mean that I won't be able to rent any of the units out as a short term rental since 1 unit in the triplex is already 33% of the units? Does anyone have experience with these laws in Raleigh?
