Honolulu Mayor Rick Blangiardi said on Monday that he plans to sign Bill 41, legislation cracking down on short-term rental operators on Oahu.

The bill, which passed 8-1 at the Honolulu City Council last week, increases the minimum booking period for rentals in most areas of Oahu from 30 days to 90 days. Short-term stays would still be allowed in resort areas and in specific areas around resort zones.

The new law will also impose new restrictions, fees and fines on short-term rentals; prohibit unregistered operators from advertising daily rates; require non-conforming units in residential areas to limit visitors to four adults; and require off-street parking for rentals in residential areas.

The version of the bill passed by the council differs from what Blangiardi’s administration initially proposed, but the mayor said he still supports it.

“I’m very passionate about Bill 41,” he said. “We’ve said all along that we were going to step in and do something about illegal vacation rentals. We worked very closely and very long on this particular project, and I was very grateful to see that it passed 8-1, and I fully intend to sign it into law.”

The law will take effect 180 days after its approval.
