A four-bedroom plantation cottage at 109 Baldwin Avenue closed for $1.3 million in February 2026. It measures 1,054 square feet, was built in 1939, and by any tape measure looks like a dozen other weathered Paia houses within shouting distance of the post office. Six comparable homes nearby sold for an average of $934,000. The gap between those two numbers, $366,000, has nothing to do with the roofline, the kitchen, or the lot size. It comes down to a zoning designation most buyers never think to ask about until they're already comparing two listings that look identical on paper.
That designation is B-CT, short for Country Town Business District, and in Paia it draws a line through the middle of town that quietly splits home values in two.
What B-CT Actually Allows
Maui County Code Chapter 19.15 created the B-CT designation to preserve the commercial character of small, remote communities like Paia while still permitting residential use on the same parcel. In plain terms: a house zoned B-CT can operate as a single-family home today and, without a zoning change, become a salon, spa, boutique, office, restaurant, or gym tomorrow. The same 1,000-square-foot cottage that houses a family this year could house a storefront next year, and the property doesn't need a variance or a rezoning application to make that switch.
Most of Paia is not zoned this way. The B-CT footprint is narrow, running along a stretch of Baldwin Avenue and the Hana Highway core near the post office and the public parking lot, the commercial spine that gives Paia Town its density of shops, galleries, and restaurants. Step off that spine onto a side street and the zoning reverts to standard residential, R-1 in most cases, where the only legal use is a single-family home.
Two houses can sit two hundred feet apart, both built in the plantation era, both needing the same amount of work, and only one of them can legally become a business without asking the county for permission first.
The Premium Shows Up on the Closing Statement
The 109 Baldwin Avenue sale isn't a one-off. Listing agents marketing B-CT parcels in Paia routinely lead with the zoning before they mention the square footage, because the zoning is what buyers are actually paying for. One nearby B-CT listing was marketed as a live-work opportunity where a family could keep the existing home and lease out an additional structure on the same lot to a business tenant, a use that isn't available to a neighbor on a straight residential parcel no matter how charming the house.
Part of the premium also comes from something more mundane: parking. Private, on-site parking is scarce in Paia Town, where most commercial traffic competes for a handful of public spaces near the post office. A B-CT parcel with its own driveway solves a problem that every future salon, boutique, or café owner in that corridor will eventually have to solve, and that scarcity gets priced in alongside the zoning flexibility itself.
Here's how the two Baldwin Avenue comps line up:
| 109 Baldwin Ave | Six-comp average nearby | |
|---|---|---|
| Zoning | B-CT | Mixed, mostly R-1 |
| Built | 1939 | Varies |
| Size | 1,054 sq ft | Varies |
| Sale price | $1,300,000 | $934,000 |
| Sold | February 2026 | Recent comparable sales |
Redfin's own automated valuation model actually placed the home's estimate at 69.8 percent above that six-comp average, higher than the closing price itself, which suggests the market may still be catching up to how much the zoning line is worth. The $366,000 gap between the actual sale and the comp average is the number a buyer can verify. The larger estimate is a signal that the premium hasn't fully settled yet.
Why the Line Doesn't Move on Demand
If B-CT zoning is worth that much, the obvious next question is whether a residential lot nearby can simply apply for the same designation. In practice, that's a harder path than it sounds.
A separate Baldwin Avenue property, currently zoned straight R-1 on a lot just under 10,000 square feet, is being marketed explicitly around its rezoning potential rather than its current use. The listing pitch is that with a successful application to R-3 or a multi-use designation, the land could support multi-tenant housing or retail. That's a bet on a future county decision, not a guarantee, and it's a meaningfully different transaction than buying a parcel that already carries B-CT rights.
Rezoning in Maui County runs through the county's community plan process, and B-CT districts specifically were created to implement provisions already written into those community plans for small, remote commercial areas. That means a rezoning application isn't just a paperwork exercise. It has to align with planning goals the county has already set for Paia as a whole, and there's no guarantee the outcome favors the applicant. Buyers treating a residential lot as a future B-CT parcel are pricing in county approval that hasn't happened and may not happen on their timeline.
This friction is exactly why the existing B-CT parcels command their premium. Supply is fixed by a zoning map drawn years ago, and expanding that footprint requires a public process rather than a private decision.
What This Means If You're Comparing Two Paia Listings
The practical takeaway for anyone shopping Baldwin Avenue or the Hana Highway core is simple: don't let the finishes decide the comparison before the zoning does. Two listings with nearly identical square footage, age, and condition can carry entirely different upside depending on which side of the B-CT line they sit on. Before you fall for a kitchen renovation or a mango tree in the backyard, ask your agent to pull the parcel's zoning designation directly, because it won't always be obvious from the listing photos or even the listing description.
It's also worth checking what a B-CT designation would actually let you do with a specific property, since permitted uses like a restaurant or spa can still trigger their own permitting requirements even when the underlying zoning allows them. Zoning tells you what's possible. It doesn't tell you what's simple.
This context matters more given where the broader Maui market sits right now. Across Maui County, the median single-family home price was $1,150,000 in July 2026, down 13 percent from a year earlier, with homes taking a median of 75 days to sell. In a market where overall prices are softening, a fixed-supply zoning advantage like B-CT is one of the few things holding its value independent of the broader trend, which is exactly why it's worth understanding before you write an offer rather than after.
Frequently Asked Questions
Is B-CT zoning unique to Baldwin Avenue? No, it applies to a defined commercial core within Paia Town, primarily along Baldwin Avenue and the adjacent stretch of the Hana Highway near the post office. The designation exists to protect the commercial character of small, remote Maui communities, so it's worth confirming a parcel's exact zoning rather than assuming based on the street name alone.
If I buy a B-CT property, do I have to run a business out of it? No. B-CT zoning permits a single-family residential use alongside the option for commercial use. You can buy the home, live in it, and simply hold the option to convert or lease it commercially later, which is part of why these parcels attract both homeowners and investors.
Can a residential lot near Baldwin Avenue eventually become B-CT? It's possible but not guaranteed, and it runs through Maui County's community plan and rezoning process rather than a simple paperwork request. Treat any listing marketed around future rezoning potential as speculative until county approval is actually in hand.
