Is Jomtien getting overbuilt?

Get all the data you need about the real estate market in Pattaya

Is Jomtien really building too many condos right now?

Yes. Jomtien is going through a condo-building wave large enough that overbuilding is now a real risk rather than a hypothetical one.

Jomtien was already Pattaya’s biggest condominium district before the latest cycle started. Colliers data showed that about 39.7% of the condo units offered across Pattaya since 2011 were in Jomtien. Pratumnak and central Pattaya were both below 19%.

Then came an unusually big burst of new projects. Colliers counted 13 Jomtien developments with 7,897 units launched during 2024. Several major towers from that cycle are still working their way toward completion. Aquarous Jomtien has 606 units. Seaspire has 451. Riviera Santa Monica has 447. Copacabana Coral Reef alone is close to 2,000 units.

Launches do not hit the market all at once, so 7,897 new units should not be read as 7,897 empty apartments sitting around today. Many are still under construction. But Jomtien is adding another large layer of supply on top of a condo base that was already much bigger than anywhere else in Pattaya.

That is enough to take the overbuilding question seriously.

Is Jomtien carrying too much of Pattaya’s condo supply?

Probably yes. Having around 40% of Pattaya’s long-run condo supply in Jomtien creates a concentration problem when developers keep choosing the same area for large new projects.

There are good reasons developers like Jomtien. The beach is long, there has historically been more land available than in Wongamat or central Pattaya, and developers can build large resort-style projects with pools, gardens and hundreds of apartments without paying the same land price as prime central locations.

But the same advantages keep attracting similar projects.

Copacabana Coral Reef, Aquarous, Riviera Santa Monica and Seaspire are different developments, yet all need buyers who want some version of the same thing: a Pattaya second home, sea access, resort facilities, rental potential or a relatively affordable Thai beach property.

Each project can make sense on its own while the area around it still ends up with too many comparable units.

That concentration is the part of the Jomtien story that is hardest to dismiss.

Are developers still flooding Jomtien and Pattaya with new condos?

No. Developers have already pulled back sharply from the previous launch pace, which lowers the chance that Jomtien turns into an uncontrolled supply spiral.

CBRE counted 3,377 new condo units launched across Pattaya in the first half of 2025. The number dropped to 1,716 in the second half, down almost half between the two periods. CBRE also noted that no project launched in the second half contained more than 320 units.

The latest broader EEC figures reinforce that change. REIC reported 1,433 units receiving land-allocation approval in the first quarter of 2026, down 45.5% from 2,629 a year earlier. REIC also found no new condominium construction permits in the EEC during that quarter.

Developers are clearly behaving more cautiously now.

This helps Jomtien because future supply can still be reduced. What developers cannot easily remove is the stock already under construction from the previous boom.

Supply measure	Earlier level	Later level	Change
Pattaya condo launches	3,377 units	1,716 units	H1 to H2 2025: -49%
EEC land-allocation units	2,629	1,433	Q1 YoY: -45.5%
EEC approved projects	30	21	Q1 YoY: -30%
New EEC condo construction permits	More than zero	None reported	Q1 2026

When will we really find out whether Jomtien is overbuilt?

The real test for Jomtien should come around 2027–2029, when several large projects start handing over apartments within a fairly short window.

Aquarous Jomtien currently expects completion in 2027. Copacabana Coral Reef also advertises 2027. Riviera Santa Monica is scheduled later, while Seaspire currently gives a completion date around 2029.

This is when presale supply becomes actual housing supply.

A condo bought off-plan does not compete for a tenant today. Once the keys are handed over, that same condo can immediately become a rental listing or resale. If hundreds of buyers in several nearby projects had the same investment plan, Jomtien can suddenly get a lot more available apartments without another tower being launched.

The completion calendar is more important now than the number of cranes visible from the beach.

Project	Approx. units	Current expected completion	Why we are watching it
Copacabana Coral Reef	~1,900	2027	Huge single-project addition
Aquarous Jomtien	606	2027	Large project entering the same cycle
Riviera Santa Monica	447	2028	Adds more resort-style inventory
Seaspire Jomtien	451	2029	Another major beachfront-oriented project

Are Jomtien condos actually struggling to sell today?

Not across the board. Jomtien still has enough buyers for good projects to sell, so this is not a market where demand has disappeared.

Luxury and beachfront projects have continued finding buyers even as Thailand’s wider housing market has weakened. Current listings for Aquarous, Seaspire and other new developments also show developers still asking large premiums over older Jomtien condos.

Jomtien is not sitting in obvious distress today.

The bigger issue comes after the first sale. An apartment sold by a developer can return to the market two years later as a resale or rental. Strong presales show that developers found investors; they do not necessarily show how easily those investors will later find tenants or buyers.

For Jomtien, secondary-market liquidity will tell us more about overbuilding than glossy presale percentages.

Is Jomtien becoming too dependent on condo investors?

Yes. A lot of new Jomtien supply is aimed at people buying a second home or an investment, and those buyers can disappear much faster than people who genuinely need somewhere to live.

Look at what developers are building. Aquarous starts with one-bedroom units around 35 square metres. Seaspire includes studios around 30 square metres. Riviera Santa Monica has 337 one-bedroom units out of 447 apartments, roughly three-quarters of the entire project.

Those layouts make sense for holiday use and rentals. They also mean several projects are chasing overlapping customers.

A Russian second-home buyer, Bangkok investor or European retiree can compare Jomtien with Phuket, Bangkok, Hua Hin, Dubai or other overseas markets. If yields disappoint or another destination becomes more attractive, that capital can move.

And within Jomtien itself, buyers can switch from one project to another. Four attractive towers do not create four times as many investors.

That is where the supply risk becomes much more serious: a growing number of similar apartments are competing for a buyer base that is highly mobile.

Can foreign buyers absorb Jomtien’s new condo pipeline?

Foreign buyers can absorb a lot of Jomtien supply, but current numbers are nowhere near strong enough to assume they will clear everything developers are building.

Chonburi remains one of Thailand’s main foreign-condo markets. Pattaya draws Chinese, Russian, European, Indian and other international buyers, while Jomtien is generally cheaper than prime Phuket or central Bangkok.

The latest foreign-transfer data are nevertheless weak. REIC reported 3,241 condo units transferred to foreigners across Thailand in the first quarter of 2026, down 17.3% from a year earlier. Transfer value fell 17.9% to THB 13.46 billion.

Chinese demand is the big concern. Chinese buyers remain the largest foreign nationality nationally, but REIC has repeatedly linked their slowdown to weaker economic conditions, liquidity problems and restrictions affecting overseas capital.

Russia has been much more supportive in Pattaya, while India and other markets are becoming more relevant. That diversity gives Jomtien some protection.

Still, a district delivering thousands of investor-friendly condos would ideally want foreign demand expanding strongly. Right now, the national data are moving in the opposite direction.

Foreign condo measure	Latest reading	YoY change
Foreign condo transfers in Thailand	3,241 units	-17.3%
Transfer value	THB 13.46B	-17.9%
Foreign share of national transfer value	23.9%	Still substantial
Biggest foreign nationality	Chinese	Still #1
Main Pattaya counterweight	Russian and more diverse foreign demand	Helps, but does not remove the risk

Can Thai buyers fill the gap if foreign demand stays weak?

Probably not. Domestic demand can help Jomtien, but a large part of the new condo pipeline is too discretionary to rely on ordinary Thai homebuyers.

Thailand still has high household debt, and mortgage rejection has been a major problem in the wider residential market. CBRE has specifically pointed to high rejection rates as one reason developers are becoming more selective about new condo launches.

Jomtien also has a product mismatch with everyday domestic housing demand. A THB 5 million, THB 8 million or THB 10 million sea-view investment condo is not solving a basic housing need for most Chonburi workers.

There are Thai holiday-home buyers and wealthier Bangkok residents who like Pattaya. They matter. But they are unlikely to absorb thousands of extra units by themselves if foreign purchases slow.

Jomtien works best when several buyer groups are active at once. Depending too heavily on any single one makes the pipeline harder to digest.

Are Jomtien condo prices already showing signs of oversupply?

A little, but the evidence looks more like weak pricing power than a crash.

REIC’s latest EEC condominium price index reached 103.1, only 0.5% higher than a year earlier. Chonburi itself also rose just 0.5%.

More revealingly, REIC said higher construction materials, labour costs and land prices helped push the index upward. Part of the increase came from condos becoming more expensive to build rather than buyers suddenly becoming much more willing to pay.

The current price picture is fairly soft.

At the same time, Jomtien is nowhere near a broad price collapse. New projects can still ask THB 130,000, THB 150,000 or more per square metre depending on the project and sea view.

The pressure is easier to see in the gap between new and old stock. Jomtien has plenty of older condos at a fraction of new-build prices. Buyers have a huge range of substitutes, and that makes it harder for every new tower to keep pushing prices higher.

Is the huge price gap between new and old Jomtien condos becoming a problem?

Yes. The bigger the new-build premium becomes, the harder developers have to work to convince buyers that a new pool, lobby and sea view justify paying multiples of what an older condo costs.

Older Jomtien studios can still appear around THB 1–2 million. New developments commonly start several million baht higher, with premium projects reaching well above THB 100,000 per square metre.

New towers obviously offer more. Buyers get newer interiors, better pools, gyms, rooftop facilities, landscaped grounds and, in some cases, much better sea views.

But tenants do not always value those differences as highly as buyers do.

Someone deciding between two rentals may happily choose an older building if it saves THB 8,000 or THB 10,000 a month. A resale buyer may prefer a renovated older condo that costs half as much.

Jomtien does not need a dramatic fall in headline prices for oversupply to hurt investors. Discounts, slower resales and weaker rents can do the damage more quietly.

Can Jomtien’s rental market handle thousands more condos?

Probably not at consistently attractive yields. Jomtien has real rental demand, but the market is seasonal and the next completion wave will give tenants even more choice.

Jomtien works well for retirees, long-stay visitors, remote workers and holiday renters. It is quieter than central Pattaya, has a long beach and has enough restaurants and services for people to stay for months rather than days.

The weakness is that rental demand changes a lot through the year.

Independent Pattaya rental trackers have estimated very strong occupancy during peak periods but much softer occupancy during parts of the low season. The exact percentage varies massively by building, unit and rental strategy, so there is no trustworthy single “Jomtien occupancy rate.”

What we can say with much more confidence is that adding hundreds of similar furnished one-bedroom units will make owners compete harder for the same tenants.

A rental investment does not need to sit empty all year to disappoint. A few extra vacant months, a lower monthly rent and higher agent commissions can turn an attractive advertised gross yield into something fairly ordinary.

That risk is higher now because so much new Jomtien stock has been sold using an investment story.

Can Airbnb and Pattaya tourism soak up the extra Jomtien condos?

No. Tourism gives Jomtien a huge pool of potential guests, but the latest Pattaya numbers show that even a busy tourist city can have too much accommodation competing for them.

CBRE counted 13.7 million visitors to Chonburi in the first half of 2025 and 13.8 million in the second half. Yet the second-half total was actually 0.6% lower than a year earlier.

Meanwhile, Pattaya’s hotel supply kept growing. CBRE counted 34,743 hotel rooms across 161 properties by the second half of 2025, up from 31,581 rooms across 141 properties in 2024. Hotel occupancy and average room rates both weakened in the later period.

Condo landlords are competing inside that accommodation market too.

There is also a legal issue with nightly rentals. Owners cannot simply assume that every condominium can operate like a hotel without considering Thailand’s hotel rules, building regulations and juristic-person policies.

Tourism definitely helps Jomtien. It just does not give every new investor an automatic tenant.

Pattaya tourism indicator	Earlier figure	Later figure
Chonburi visitors	13.7M in H1 2025	13.8M in H2 2025
H2 visitor growth YoY	—	-0.6%
Pattaya hotel rooms	31,581 in 2024	34,743 in H2 2025
Hotel properties	141 in 2024	161 in H2 2025
H2 hotel performance	—	Occupancy and ADR both declined

Are beachfront Jomtien condos safer from overbuilding?

Yes. Real beachfront sites and exceptional sea views have much better protection than generic Jomtien apartments because buyers cannot create more coastline.

That difference is easy to miss when people talk about “the Jomtien market” as though every condo competes equally.

Seaspire markets itself around an absolute beachfront position. AROM Jomtien also leans heavily on beachfront scarcity. Those properties have something that a tower several streets inland cannot reproduce, however good its swimming pool is.

Jomtien’s older inland inventory has the opposite problem. There are many buildings, many similar studios and plenty of units that can substitute for one another.

If supply pressure worsens, the adjustment should be uneven. Generic small units bought at high new-build prices should feel it first. Truly scarce beachfront property has a much stronger chance of holding buyer interest.

Will the upgraded Jomtien Beach create enough demand for all these condos?

No, but it should make the best Jomtien locations more attractive.

The Marine Department is currently carrying out the second phase of Jomtien’s beach nourishment project. The work covers about 2.85 kilometres and is designed to widen the beach to roughly 30–50 metres in the treated sections.

That is a meaningful improvement. A wider beach gives tourists and residents more usable space and improves the one feature that underpins Jomtien’s entire property market.

Still, the benefit spreads across the neighbourhood.

Someone living in an older condo can use the same improved beach as someone who just paid THB 8 million for a new unit. The project makes Jomtien better, but it does not suddenly make thousands of new condos scarce.

The biggest benefit should go to buildings that combine the improved beach with genuinely good access and views.

Will U-Tapao airport and the EEC save Jomtien from oversupply?

Not anytime soon. The EEC and U-Tapao can support Jomtien over the long run, but using unfinished infrastructure to justify today’s condo pipeline is too optimistic.

Chonburi has a real industrial economy. Logistics, manufacturing and EEC investment create jobs and bring more business activity into the province.

The connection to Jomtien condos is weaker than developers sometimes imply.

Someone working in an industrial estate does not automatically want a resort condo beside the beach, especially when cheaper housing sits closer to work. The expanded U-Tapao airport and associated infrastructure could eventually bring more visitors and residents, but the main airport expansion is still years away from expected commercial operation.

The same caution applies to the high-speed rail project linking the three airports. Its timetable has shifted repeatedly.

These projects are useful upside for Jomtien. We would not count their future users as today’s condo demand.

Are developers reacting quickly enough to avoid a serious Jomtien glut?

So far, yes. The sharp slowdown in new Pattaya launches suggests developers have noticed that the market cannot keep absorbing giant projects at the previous pace.

As seen above, Pattaya launches fell from 3,377 units in the first half of 2025 to 1,716 in the second half. The latest EEC approval data also show a much slower supply environment.

That is exactly what we would want to see if the market is getting too crowded.

Developers can postpone future projects, shrink them or wait for existing inventory to sell. Those decisions make a prolonged glut less likely than if launches were still accelerating today.

The uncomfortable part is timing. Much of Jomtien’s next supply wave was committed before developers started braking.

So the slowdown helps, but it arrived after several large projects were already on their way.

What would tell us that Jomtien has definitely become overbuilt?

Jomtien will look clearly overbuilt if completed condos start piling up faster than buyers and tenants can absorb them, especially after the 2027–2029 handovers.

The first place to watch is the resale market. If hundreds of owners receive keys and quickly list similar one-bedroom units, sellers will start competing directly with one another.

Rents are the second test. Falling asking rents, free months, unusually high agent commissions or much longer low-season vacancies would show that tenant demand is struggling to keep up.

Developer behaviour also matters. Heavy furniture packages, guaranteed-return schemes, extended payment plans and repeated price promotions can reveal weak demand before official price indices move much.

Foreign transfers are another important test. If international purchases remain weak while the current Jomtien pipeline completes, absorption becomes considerably harder.

No single one of these indicators would prove a glut. Several appearing together would.

What to watch	Normal market	Clearer overbuilding warning
Resale listings	Rise gradually	Jump after project handovers
Selling times	Relatively stable	Units sit for much longer
Rents	Hold reasonably well	Asking rents fall
Low-season vacancy	Manageable	Becomes noticeably longer
Developer incentives	Occasional	Persistent and aggressive
Foreign demand	Recovers	Remains weak
New launches	Stay disciplined	Another large wave begins

Is Jomtien getting overbuilt?

Yes, particularly in small investor-oriented condos, although Jomtien has not reached the point where the whole market looks badly oversupplied.

The evidence has become harder to ignore. Jomtien already held roughly 40% of Pattaya’s long-run condo supply before the latest boom. Then came nearly 7,900 units across 13 Jomtien projects in 2024, followed by several large developments that will hand over mainly during the next few years.

Demand is still there. Pattaya attracts millions of visitors, Jomtien remains popular with foreign buyers, and good beachfront property still has real scarcity.

But the current demand numbers do not look strong enough to make all that new supply harmless. Foreign condo transfers across Thailand recently fell 17.3% year over year. The latest EEC condo price index rose only 0.5%, with REIC saying rising construction and land costs helped drive even that modest increase. Pattaya hotels have also been adding rooms while occupancy and room rates softened.

Developers seem to understand the problem. New Pattaya condo launches fell sharply in the second half of 2025, and the latest EEC data show a much more cautious supply environment. That should prevent the situation from becoming much worse.

For now, the clearest risk sits with generic studios and one-bedroom investment units bought at high new-build prices. Jomtien already has plenty of alternatives, and several hundred similar units can hit the rental and resale market at almost the same time when a large tower completes.

Prime beachfront condos are a different proposition because their location is harder to copy.

So yes, Jomtien is getting overbuilt at the commodity end of the condo market. The area itself still has enough demand to avoid a blanket property glut, but buyers can no longer assume that simply owning a new Jomtien condo will produce easy appreciation or easy rental income. The next completion wave should make that distinction much more obvious.
