Skyline OC is a twin tower high rise condominium community at 9 MacArthur Place in Santa Ana, zip 92707, in the South Coast Metro district. The towers stand on the MacArthur Place campus just north of the 405, around a lake, with South Coast Plaza and the Segerstrom Center for the Arts across the freeway and John Wayne Airport a few minutes down MacArthur Boulevard. The county assessor carries a year built of 2008 on every residence that has traded here, and the master association holds 349 residences. The current offering is a condo transformation, and residences are identified by tower letter and floor plan letter, so a listing may read Residence N803, Plan E.
That combination is worth understanding before you shop here. The building is not new. What is new is the interior product and the way it is being brought to market. If you are comparing Skyline OC to genuinely new construction elsewhere in Orange County, compare the systems and the reserve position, not just the finishes.
Security is high rise grade: twenty four hour security, an automatic gate and card or code access, with assigned parking behind a controlled entrance. The life here is a full service building in the middle of the county's commercial center. You take the elevator down to the pool deck, walk to dinner at the Plaza, and get to the airport, the Irvine office parks or the 73 toward the coast in minutes. Nobody here mows a lawn.
Three buyers choose a high rise in South Coast Metro over a garden condominium at the coast. The first is the downsizer who is finished with a house in Irvine, Tustin or North Costa Mesa and wants everything on one floor with a doorman, a gym and a pool they never clean, and who treats the dues as the price of never calling a contractor again. They buy the two bedroom plans on the higher floors and they pay the floor premium willingly, because the view is the point. The second is the professional working the airport corridor, the Irvine business complex or the hospitals along the 405, who wants a lock-and-leave home ten minutes from the office and a direct shot to the terminal. They buy the large one bedroom plans and they are the most sensitive to the monthly carrying cost. The third is the buyer who wants square footage and a modern building and has done the math on what the same money buys in coastal Newport Beach, which is roughly half the square footage in a forty year old garden community. They buy whichever plan clears their budget with the dues included.
What separates Skyline OC from the communities it gets compared to is the building type, and everything follows from that. The gated garden communities on the Newport bluff, Villa Balboa and Villa Point among them, sell two and three story buildings, assigned garages and a coastal address, with dues that pay for grounds and a pool. The 1970s townhome communities on the Costa Mesa side of South Coast Metro sell an attached home with a patio and a garage at the lowest price per foot in the district. Skyline OC is a true high rise, which means elevators, structural insurance, a staffed lobby and a view that no low rise can offer, and dues that are a multiple of either comparison. The Skyline buyer is buying the tower and the service. The buyer who wants a patio and a garage door goes elsewhere.
South Coast Metro is the densest concentration of retail, dining and performing arts in Orange County, and Skyline OC sits inside it rather than near it. South Coast Plaza and the Segerstrom Center are minutes away. John Wayne Airport is close. The 405, the 55 and the 73 are all reachable quickly, which is the practical argument for this address over a coastal one at the same price.
The MacArthur Place setting also gives the towers something unusual for a high rise: a lake. Residences facing the lake carry lake views, and the other exposures look out over the city and to the mountains. Which direction a residence faces is a real pricing input rather than a marketing line.
Association dues at Skyline OC run from $1,341 to $1,429 per month across the residences currently in the MLS. That is the single most important number on this page, and here is why.
On a $649,600 one bedroom, $1,398 a month is $16,776 a year, or roughly 2.6 percent of the purchase price every year. For comparison, using the same math on the other communities I cover on this site:
That is not a criticism of Skyline OC. It is what a full service high rise costs to operate. Elevators, structural insurance, twenty four hour staffing, a pool deck, a gym and common area utilities in a twenty five story building are simply more expensive per unit than they are in a two story garden community. But it changes the arithmetic of what you can afford, and it changes what your carrying cost looks like in year ten. Underwrite the dues, not just the price.
What the dues cover:
Skyline OC is fee simple. There is no land lease here.
Through the autumn this building was handing out the cleanest piece of evidence I have found in any Orange County high rise: two residences on the market with the identical 1,198 square foot one bedroom plan, one on the fourth floor at $649,600 and one on the fourteenth at $724,480. Same plan, same square footage, $74,880 apart, which works out to roughly $7,500 a floor, or about $62.50 per square foot, purely for elevation.
Both have since left the market, so that pair is now a record rather than a shopping list. The four residences standing today are four different plans, so they do not isolate elevation the same way, but they point the same direction: $588 per foot on the third floor, $692 on the ninth, $751 on the fifteenth and $813 on the twentieth.
Use that. If you are choosing between a lower floor and a higher one, you now know what the building itself thinks the difference is worth, and you can decide whether you agree.
Price per square foot across the six MLS records runs from $520.07 to $692.04. That is dramatically below coastal Newport Beach, where the same money buys roughly half the square footage. Which brings up the other thing worth naming: the one bedroom plans here are 1,193 to 1,198 square feet. That is two bedroom square footage in a one bedroom layout. The low price per foot is real, but part of what you are buying is a lot of feet.
Only two sales closed through the MLS in the window: a one bedroom at $620,440 against a $635,440 list, and a two bedroom at $851,825 at full list. Both closed in under a month.
That thin closed record is itself the most useful thing to know about buying here. Most transactions at Skyline OC do not run through the MLS, because they are sold directly. Which means the automated value estimates you see on the portals for this building are built on almost no public data, and a comparable sale analysis using only MLS records will miss most of what has traded. If you are buying or selling here, the number that matters is the one the sales office has, not the one Zillow shows you.
Four residences are on the market as of November 1, 2026:
The whole board has turned over since September and the range has moved up at the top, from $999,999 to $1,298,250. What has not changed is the shape: the per foot number rises with every floor, from $588 on the third to $813 on the twentieth. The two with real market time on them, at 62 and 73 days, are the two lowest in the stack.
What are the HOA dues at Skyline OC?
Between $1,341 and $1,429 per month across the residences currently in the MLS. Confirm the figure for the specific residence you are considering.
Why are the dues so high?
Because it is a full service twenty five story high rise. Elevators, structural insurance, twenty four hour staffing, common area utilities and a full amenity deck cost more per unit than they do in a low rise community. On a $649,600 residence the dues work out to roughly 2.6 percent of value per year, against 0.6 to 0.9 percent at the Newport Beach communities I cover on this site.
When was Skyline OC built?
The county assessor carries 2008 on every residence that has traded. The current offering is a condo transformation, so the finishes are new even though the structure is not.
How many residences are there?
349 residences in the master association.
Where is Skyline OC?
9 MacArthur Place, Santa Ana, zip code 92707, in South Coast Metro near South Coast Plaza and the Segerstrom Center.
Is Skyline OC on a land lease?
No. Skyline OC is fee simple.
What amenities does Skyline OC have?
Pool, spa, sauna, fire pit, barbecue areas, a gym and exercise room, a clubhouse and meeting room, a dog park, a bocce ball court, storage, controlled access and twenty four hour security. Gas and trash are included in the dues.
Is Skyline OC secure?
Yes. Twenty four hour security, an automatic gate and card or code access, with assigned parking behind a controlled entrance.
What do residences cost at Skyline OC?
The four residences in the MLS as of November 1, 2026 are asking $685,987 to $1,298,250. The two that closed through the MLS in the window sold at $620,440 and $851,825.
What is the price per square foot?
Between about $520 and $692 across the six MLS records. That is well below coastal Newport Beach for comparable square footage.
How big are the one bedroom plans?
Around 1,193 to 1,198 square feet, which is unusually large for a one bedroom and is part of why the price per foot looks low.
Does the floor matter to price?
Yes, and it is measurable here. The same 1,198 square foot one bedroom plan is asking $649,600 on the fourth floor and $724,480 on the fourteenth. That is about $7,500 per floor.
Why are there so few sales on Zillow for this building?
Because most transactions here are sold directly rather than through the MLS. Public portals only see a fraction of what trades, so automated estimates for Skyline OC are built on very little data.
Are there lake views?
Yes. Residences facing the MacArthur Place lake have lake views, and the other exposures look out to the city and the mountains.
