In 2022, Honolulu passed one of the strictest vacation rental laws in the country, and it worked exactly as written. Bill 41 pushed short-term rentals out of residential neighborhoods and into three resort pockets: Waikīkī, Ko Olina, and a small strip near Turtle Bay. Kailua, the neighborhood the bill's own sponsors named as the problem, lost its illegal Airbnb inventory almost overnight.
The housing problem the bill was supposed to fix did not go away. Kailua is still one of the two most expensive places to buy a home on Oʻahu, and its rents rank second in the state. If you are comparing windward neighborhoods and assumed the vacation rental crackdown would show up as a price break, the data says otherwise.
The Case Made For Bill 41
The argument for Bill 41 was straightforward and made in public testimony. Save Oʻahu Neighborhoods, the group that backed the bill, argued that homes used as vacation rentals were homes taken out of the long-term supply. Executive director Larry Bartley told the city council that
"those apartments were built for people to live in permanently or rent long-term"
and that pulling short-term rentals back into that pool would ease pricing pressure across the island. Mayor Rick Blangiardi framed it the same way when he signed off on the measure, arguing that residential neighborhoods had effectively been rezoned for tourism without anyone voting on it.
The mechanism behind that argument is simple supply-and-demand logic. Take units out of the vacation-rental pool, and owners either rent them long-term or sell them to someone who will live there. Either way, more housing becomes available to residents, and prices soften.
The Realtor Who Called It Early
Not everyone expected that mechanism to fire. Century 21 iProperties Hawaii Realtor Abe Lee, discussing Bill 41 with Hawaii Business Magazine in 2022, pointed out that Kailua owners already knew short-term rentals were illegal there under the 2019 predecessor law, Bill 89. Extending the minimum rental period from 30 days to 90, he argued, wasn't going to change much behavior that had already adjusted.
"I don't think it's as impactful as the other bill was."
Hawaii Business Magazine's own reporting backed him up before Bill 41 even passed. Looking back at what happened after Bill 89 took effect in 2019, the magazine found no sharp increase in for-sale or for-rent inventory in the neighborhoods known for illegal vacation rentals, and named Kailua specifically as one of them. The mechanism had already failed to show up once.
Three Years Later, By The Numbers
Here is what island-wide MLS data actually shows for Kailua's single-family market since the crackdown took full effect.
| Period | Median Sale Price | Sales Volume | Days on Market |
|---|---|---|---|
| November 2025 | $1,685,000 | 259 homes | 18 days |
| June 2026 | $1,735,000 | 251 homes | 19 days |
Prices rose 5 percent year over year through June 2026, active listings crept up to just 67 homes islandwide for the whole neighborhood, and homes were still selling in under three weeks. Kailua remains Oʻahu's second-highest-priced single-family market, trailing only Waialae-Kāhala.
Rents tell a similar story. The University of Hawaiʻi Economic Research Organization's 2026 Housing Factbook lists Kailua's median asking rent at $3,316 a month, using 2024 Census figures, the most recent year available. That ranks second in the state, just behind neighboring Hawaiʻi Kai at $3,501. If Bill 41 had converted a meaningful chunk of former vacation rentals into long-term housing stock, Kailua's rent ranking would be the first place you'd expect to see it soften. It hasn't.
Where The Units Actually Went
The gap between the policy's logic and its outcome comes down to what owners actually did once the vacation-rental income disappeared.
A parallel case makes the pattern clear. When Hawaiʻi County commissioned an economic impact study ahead of its own short-term rental restrictions, the study found that only 4 percent of surveyed owners said they would convert their properties to long-term rentals if restrictions took effect. Most owners weren't choosing between "rent nightly" and "rent for a year." They were choosing between "rent nightly" and "sell to someone who wants to live here full time," or simply holding the property as a second home.
That distinction matters because a sale to an owner-occupant does not add a rental unit to the market. It removes a listing from the for-sale pool and converts it directly to owner-occupied housing, which is exactly the outcome fair housing policy should want, but it does nothing to soften rents or resale prices in a neighborhood where buyer demand for that lifestyle is already high. Kailua's beach access, walkability, and town character were pulling in owner-occupants long before Bill 41 passed. Taking the vacation-rental option off the table didn't reduce that demand. It may have simply funneled more of it into ownership.
Financing adds another layer. Lenders underwriting a Kailua purchase now typically evaluate only long-term or 30-day-plus lease income when qualifying a buyer, which changes the math for anyone who bought expecting nightly-rate cash flow to carry part of the mortgage. Insurance has tightened too, with far fewer carriers on Oʻahu still willing to write coverage that includes short-term rental activity. Both changes discourage casual STR conversion, but neither one adds affordable inventory. They just make the old business model harder to run.
The Legal Wrinkle Still Working Through Court
Bill 41 also tried to raise the minimum stay for unpermitted units from 30 days to 90. A federal judge, Derrick Watson, blocked that specific piece in 2022 before it ever took effect, ruling that the rule swept in people who were never the intended target: residents mid-move between homes, patients in Oʻahu for medical treatment, and military families in transition between duty stations. That carve-out is not a footnote. If you are relocating on military orders and need 60 or 90 days of housing while you close on a home or wait for base housing to open up, the legal fight over how broadly Oʻahu can define a "vacation rental" is still relevant to your own housing options, not just to investors.
What This Means If You're Comparing Neighborhoods
If a headline about Kailua's vacation rental ban is part of why you assumed the neighborhood might be more affordable than its reputation suggests, the three years of data since the law took effect argue otherwise. Kailua's home prices and rents have both kept climbing on a track that looks a lot like the rest of Oʻahu's east side, regardless of the enforcement crackdown. The lesson isn't that the policy failed on its own terms. Fewer illegal rentals in residential streets was the actual, stated goal, and that goal was met. The lesson is that a supply-side housing argument and a quality-of-life argument were bundled into one bill, and only one of them delivered.
For a buyer weighing Kailua against Kāneʻohe, Hawaiʻi Kai, or the North Shore, that means judging the neighborhood on what it actually offers rather than on an assumption about future affordability that the numbers haven't supported yet.
Frequently Asked Questions
Does the vacation rental ban affect a regular home purchase in Kailua? Not directly for owner-occupants. The restriction targets nightly and short-term rental use, not primary residence or standard long-term leasing. It matters most if you were counting on rental income to offset the mortgage.
Can I still buy income property in Kailua? You can buy and rent long-term. Short-term rental use outside a small number of grandfathered, pre-1989 nonconforming permits is not legal in Kailua under current rules, and enforcement has continued into 2026.
Buying or selling on the windward side means reading past the headline on any given policy and into what the transaction data actually shows. That's the kind of read Tia Perez does for clients across Kailua and the rest of Oʻahu every day.
