HONOLULU - Local Five, the hotel workers’ union took aim at online companies like air b-n-b, with a campaign to influence the outcome of legislation this session.

An ad launched this week, focuses on the booming number of housing units taken out of the long term-rental market and put into short term

 "This is Kailua. This is Waipahu. Now, add all the homes in both places together that's how many homes have turned into vacation rentals by companies like air b-n-b from the mainland. 33,000 homes now, 399 more each month, 9,000 in Maui alone," is the voice over.

"We don't have enough housing for our people to live. They say we need 30,000 homes to address that home shortage and here we are taking 30 thousand homes and turning our neighborhoods into hotel districts. We are against that," said Local Five union leader Eric Gill.

Lawmakers in both houses held hearings this week on bills that try to manage the online marketplace.

The House passed out two bills on the floor Friday that try and manage vacation rentals.

Some cautioned that the bills don't go far enough, or get into a problem of regulation that others think is a city and county problem.

"A lot of us in this Chamber have a lot of the illegal operators taking away housing from our local families," said Rep. Cynthia Thielen.

"We have 8.6 million tourists, where are they going to stay? There is not enough space in the hotels. This is a black market created out of the lack of understanding, response or being afraid to legislate otherwise what is a strong economic need," said Rep. Gene Ward.

Local Five believes there are more people renting out their homes now--than there are hotel rooms in Waikiki.

The Senate heard four bills this week including one to set up a task force to address the vacation rental issue.

 A bill proposed by air b-n-b was advanced by a joint Senate committee on Tourism and Consumer Protection.

It allows companies like air b-n-b, Home Away and VRBO to collect taxes owed to the state.

The governor supports the intent because the state needs the money.

But last year he vetoed a bill to do just that, because of the untended consequence of encouraging rentals, which clashes with the city's ability to regulate the booming industry.

"We need to have the ability to audit to make sure those properties are legal and authorized and paying their taxes, and we will continue to look for solutions that allow us to do that," said Gov. David Ige.

Vacation rentals, it was a hot button issue last year and so far, it shows no sign of cooling off.
