At ONE Carmel, the Twelfth Building Permit Matters More Than the Lot You Pick

ONE Carmel launched sales by the end of June 2026 on the 891 acres in Carmel Valley long known as September Ranch. Most of the coverage has been about the asking prices and the hillside views. For anyone planning to build, one condition attached to the project matters more. When the 12th market-rate building permit can be issued depends on progress on 22 inclusionary homes elsewhere in the subdivision. All 22 have to be finished before the 41st permit can be issued.

That makes ONE Carmel a different purchase from a resale in Carmel or Pebble Beach. A buyer here is buying into a 2010 entitlement. That entitlement fixes where the house can sit, where its water comes from, and how quickly the neighborhood around it can fill in. The lot itself is the smallest part of what the buyer agrees to.

Two Readings of the Same Condition

The rule linking affordable and market-rate construction has been described two ways in public records, about six years apart.

The first row comes from the Board of Supervisors report accepting the Phase 1 final map. The second comes from Monterey County NOW's account of the July 8 Planning Commission hearing. There, Marshall told commissioners that "half of all the inclusionary housing building permits must be issued prior to the 12th market-rate building permit."

Under either reading, the gate falls at the same two points. The County's July 2026 resolution adds another step. A "final and amended" Inclusionary Housing Master Development Agreement must exist before the final map for the affordable-housing parcel can be recorded. The public documents reviewed here don't show whether that amended agreement has been executed or what wording it ends up with. Monterey County NOW summed up the practical effect directly: how quickly the affordable units arrive "depends on how fast sales and permitting of the luxury units take place."

The 12th person to pull a market-rate permit depends on the affordable homes moving ahead on schedule. An early buyer who builds quickly may never run into the gate. A buyer who lands in the middle of the sequence could find their timing depends on a parcel they will never own.

How the Affordable Parcel Is Moving

The inclusionary homes, called ONE Grove, sit on a 4.47-acre parcel near Carmel Valley Road between Canada Way and Valley Greens Drive. The plan calls for 15 moderate-income units and 7 workforce units: 17 two-bedroom and 5 three-bedroom homes, ranging from 1,043 to 1,201 square feet, with two community playgrounds. Under the County's income definitions, moderate-income buyers can earn up to 120 percent of area median income and workforce buyers up to 150 percent.

The Planning Commission approved the designs 10-0 on July 8, 2026. That was a design approval and doesn't mean construction has started. The June 2026 staff report said the Phase 1A final map for the parcel was "concurrently being processed" and expected before the Board "in summer 2026." The approval as amended makes recording that map a condition of any building permit for the affordable homes. As of this writing, no public record reviewed here confirms that the map has been recorded.

The affordable parcel has to clear its own steps in order. The amended agreement comes first, then map recordation, then building permits, then construction. Only after that does the market-rate side pass its own 12th-permit point.

An Entitlement With a Long Paper Trail

The 2010 resolution the whole project rests on came out of more than a decade of contest. The Carmel Pine Cone has described September Ranch as "a hot-button topic in the early 2000s."

1. December 1, 1998. The County approved an earlier plan. Save Our Peninsula Committee and the Sierra Club challenged it, and the approval was later vacated after courts found the environmental review inadequate.
2. 2001. The Sixth District Court of Appeal affirmed that more analysis was needed on water-supply baseline, water rights, and growth-inducing effects.
3. December 12, 2006. The Board approved the current configuration of 73 market-rate lots and 22 affordable homes.
4. July 21, 2009. After a 2008 judgment requiring more analysis of water demand, the County rescinded that approval.
5. November 9, 2010. The Board certified the revised environmental report and approved the project under Resolution No. 10-312.
6. December 8, 2020. The Board accepted the Phase 1 final map, creating 33 market-rate lots.

Almost every turn in that sequence concerned water. That explains why the project's water system works differently from the rest of the Peninsula, and why it limits what an owner can build.

Water From the Property, Not From Cal Am

On most of the Monterey Peninsula, a buyer's first water question involves California American Water and the state cease-and-desist order. At ONE Carmel, Cal Am hookups are barred. The subdivision draws on wells in what is called the September Ranch Aquifer, outside the Carmel Valley Alluvial Aquifer. A 2012 Monterey Peninsula Water Management District staff report set the system's production limit at 57.21 acre-feet per year across 99 connections. Cal Am's later role was limited to operating the separate ONE Carmel Mutual Water Company.

This setup works in both directions. The subdivision doesn't wait in the Cal Am queue that limits remodels and new connections elsewhere. It also can't reach Cal Am supply later. Connecting would require changes to State Water Board limits, authorization from the California Public Utilities Commission, and a County-approved amendment to the project's water condition after discretionary review. Whatever a house is designed to use comes out of a shared, fixed allocation.

The Envelope Is the Lot

The listing headline gives acreage, from 2.5 to 12 acres, with homesites starting at $6 million. The County's conditions describe each lot differently. Every lot has a surveyed building and development envelope. The rest of the lot sits under conservation and scenic easements, and the County accepted those easement deeds when the Phase 1 map was approved. Envelopes account for slope, environmental constraints, and protected or screening trees, and they set maximum building dimensions, height, and placement to keep homes off ridgelines. Each lot needs its own design approval before a building permit.

So a 12-acre lot and a 3-acre lot may differ less in buildable area than their acreage suggests. The envelope and the driveway location decide where the house goes. The view, the tree screening, and the slope are all fixed inside that boundary. The rest of the acreage adds to the roughly 90 percent of the property that Monterey County NOW reports will stay permanently protected.

Buyers can choose move-in-ready residences designed by BAR Architects & Interiors starting at $15 million, or work with ONE Carmel's roster of architects on custom estate homes starting at $15 million or trophy compounds starting at $25 million, as Robb Report described the offering in June 2026. Every one of these figures is an asking or starting price. None is a recorded sale.

What the Public Record Hasn't Settled

Several facts that affect a buyer's timeline haven't appeared in any public source reviewed for this post:

• Subdivision improvements. In June 2025, project managers told The Pine Cone that roads, electricity, gas, and water for the 36 Phase 1 homes, built by the Don Chapin Company, should be done by early 2026. No later independent report confirms they were finished.
• The 2020 security arrangement. The County estimated improvements at about $12.3 million. The owner provided a $6.5 million cash deposit, and staff proposed securing the remaining roughly $6 million with a second deed of trust. A deed restriction, executed and slated for recording with the final map, would bar the sale of the property or any individual lots while that deed of trust stayed in place. The owner said it expected to fully bond the project once the map was recorded. Sales were under way by June 2026, but no document reviewed here shows how that arrangement was finalized or later resolved.
• Lot-level approvals. No design approvals or building permits for individual market-rate lots turned up, and neither did a public count of lots sold or in escrow.
• Amenities. The developer's plans for a restored equestrian center and the preserved red barn are still described as plans.

A preliminary title report, the recorded CC&Rs, the improvement agreement, and the amended inclusionary agreement are the documents that would answer each of these.

FAQ

Who is developing ONE Carmel? The County identifies Carmel Reserve LLC as the owner. Robb Report describes the project as led by Crystal Jiang, founder and chairman of Hong Kong-listed DL Holdings Group.

Does the Peninsula water moratorium apply here? The project doesn't draw from Cal Am, so the cease-and-desist order that governs Cal Am connections works differently here. The limit is instead the subdivision's own allocation of 57.21 acre-feet per year.

Can a buyer build anywhere on their acreage? No. Construction is limited to the surveyed envelope, and the rest of the lot is under recorded easements.
