Sea Summit, San Clemente's newest master-planned community above Marblehead, has been marketed with a number that catches the eye: model homes across its four neighborhoods opened with prices starting just under $1 million. That number is technically true. It is also close to useless for anyone trying to compare Sea Summit against the rest of San Clemente's housing stock, because it describes a starting point that most of the community has already moved past, and it says nothing about what a buyer actually pays every month after closing.
This matters right now because Sea Summit is no longer a construction site with a sales trailer. It is an active resale market, and recent listings across its Sapphire, Azure, and Indigo neighborhoods have priced from the low $2 million range up into the mid $5 millions. Anyone comparing that price range against a similarly priced resale home elsewhere in San Clemente needs to understand that two $2 million listings in this city can carry meaningfully different monthly obligations, and a different physical product, depending on which side of that comparison they're standing on.
Four Neighborhoods, One Community, Different Math
Sea Summit was built by national homebuilder Taylor Morrison across four distinct tracts on roughly 100 acres above Vista Hermosa, a short walk from the Outlets at San Clemente and Miramar Food Hall. Each tract has its own footprint and its own place in the pricing ladder:
- Aqua — 127 homes, ranging from about 2,214 to 2,649 square feet, in the northern corner of the community. A portion of this tract is built as small clusters where five homes share a single driveway off one cul-de-sac street.
- Sapphire — 77 homes, from about 3,460 to 3,923 square feet.
- Azure — 81 homes, from about 3,775 to 4,686 square feet, including view-oriented lots marketed under names like the Azure Viewpoint Collection.
- Indigo — the smallest and most expensive tract, 24 homes ranging from about 4,694 to 5,544 square feet.
That's 309 homes total, and the spread in square footage across the four tracts is the first clue that "Sea Summit pricing" was never one number. The second clue is what happens to the community's cost structure once a buyer moves past the purchase price.
Mello-Roos Is the Part the Sign Doesn't Mention
Every home in Sea Summit carries a Mello-Roos assessment on top of the base California property tax rate, which sits at about 1.01% of assessed value under Proposition 13. Sales office quotes for Sea Summit's total effective rate, once Mello-Roos is layered in, have put the figure close to 1.8% since the community's early sales phases, and current buyer guidance for San Clemente's newer master-planned developments continues to flag Mello-Roos as a standing cost on top of that base rate. On top of that, homeowners pay a separate monthly HOA fee for access to the Summit Club and the community's parks and trails. In the Aqua tract specifically, that fee currently runs about $250 a month plus the potential for special assessments.
None of this appears in the "starting under $1 million" headline. It appears on the closing disclosure, and then again on every property tax bill for as long as the buyer owns the home, because unlike a mortgage payment, a Mello-Roos assessment does not shrink over time in the way principal does. It is set by the underlying bond and typically runs for 20 to 30 years from the date the community's infrastructure was financed.
The Same Price, Three Different Bills
Here is where the comparison becomes genuinely useful for anyone deciding between San Clemente neighborhoods rather than just deciding whether to buy at Sea Summit.
| Neighborhood type | Effective property tax rate | Monthly HOA | Typical lot |
|---|---|---|---|
| Older San Clemente resale (Riviera District, Pier Bowl, southwest San Clemente) | About 1.01%, no Mello-Roos | Typically none | Standalone single-family lot |
| Talega | Averages near 1.5%, varies by sub-tract | Master HOA, plus a second HOA for condo communities | Mix of detached tract homes and attached condos across roughly 40 named neighborhoods |
| Sea Summit | About 1.8% | Roughly $200 to $250 (Aqua currently $250) | Detached in Sapphire, Azure, and Indigo; Aqua includes five-home clusters sharing one driveway |
Run the same $2 million purchase price through each row and the gap stops being abstract. At 1.01% with no HOA, the annual tax bill is about $20,200, or roughly $1,683 a month. At Sea Summit's roughly 1.8% effective rate plus a $200 to $250 HOA, the same $2 million home costs about $36,000 a year in tax, or $3,000 a month, plus the HOA, for a total closer to $3,200 to $3,250 a month. That's a difference of roughly $1,500 a month for two homes priced identically on paper.
That gap doesn't shrink as Sea Summit's remaining inventory climbs toward its upper tiers. It grows, because the Mello-Roos assessment is typically tied to the home's value or lot size, not fixed at a flat dollar amount. A buyer looking at a $5 million Indigo listing is paying that same proportional premium on a much larger base.
Talega Proves There's No Single Community Number
It would be a mistake to read the table above and assume every new San Clemente community carries a clean, quotable rate. Talega is the counterexample. Development there began in the late 1990s and produced roughly 40 distinct neighborhoods, from Cantobrio to Farralon to San Rafael, each tied to its own Community Facilities District and its own bond schedule. There is no single "Talega Mello-Roos number," which is exactly why the 1.5% figure above is an average and not a quote a buyer should rely on for a specific address.
This is the detail that separates a researcher's due diligence from a portal search. The listing price tells a buyer nothing about which CFD a specific parcel sits in, and two homes on the same street in Talega can carry different assessment schedules depending on when their phase was built.
What This Means If You're Cross-Shopping San Clemente
San Clemente's broader market has stayed tight through 2026, with the tightest pockets concentrated in specific geographies rather than spread evenly across the city. As of late April 2026, Southwest San Clemente and Talega were sitting under two months of supply in many price brackets, firmly in seller's market territory, while Forster Ranch and the southeast side had crept toward three to four months, giving buyers there slightly more room to negotiate. That asymmetry matters for this comparison, because a buyer willing to look at Forster Ranch or an older non-Mello-Roos pocket of the city instead of chasing new construction may find both a lower carrying cost and a little more negotiating leverage in the same search.
None of this is an argument against buying new construction in San Clemente. A Sea Summit HOA fee buys real amenities, and the Mello-Roos bond funds infrastructure that a 1920s-era Riviera District lot never had to pay for because it was built before any of this financing structure existed. The point is narrower and more useful: the purchase price on the sign is only one part of the comparison, and the other part, the monthly carrying cost and the physical product behind the price, doesn't show up until someone does the arithmetic or asks the right questions before writing an offer.
Frequently Asked Questions
Does Mello-Roos ever go away? Eventually, yes. Most Mello-Roos bonds run 20 to 30 years from when the district issued the debt, after which the assessment is retired. Buyers should ask for the specific bond's start date and remaining term for any parcel they're considering, since two homes in the same community can be at different points in that schedule.
Are all the homes in Sea Summit's Aqua tract sharing a driveway? Current MLS-sourced descriptions for the Aqua tract note that a subset of five homes on one cul-de-sac street share a single driveway, while the tract's other homes are configured separately. Anyone specifically prioritizing a fully detached driveway should confirm the exact lot configuration for any address under consideration rather than assuming it based on the tract name.
How do I find the exact Mello-Roos assessment for a specific San Clemente address? The precise figure is tied to the parcel, not the neighborhood name, and it appears on the property's tax bill and in the preliminary title report during escrow. For homes still under construction or recently delivered, the builder's sales office can typically provide the current-year figure, but that number should still be verified against the title report before removing contingencies.
Comparing a $2 million listing in Sea Summit against a $2 million listing in Forster Ranch or the Riviera District looks like an apples-to-apples decision until the tax bill and the HOA statement arrive.
