"Two years to get this done." That was Piperton's city manager at the May 19, 2026 board meeting. He was describing how long the city has to find more sewer treatment capacity once it starts running over the amount it buys from Rossville, and it could get there within a year at its current pace of growth. If you're comparing a new build in Fayette County with a resale, that sentence matters more than any rendering in a sales office. It points to what's actually setting the county's new-home supply right now: pipes, treatment capacity, and a town policy in Oakland adopted this summer.
Piperton's sewer comes from a lagoon in Rossville
Piperton doesn't run its own sewer treatment. It buys treatment capacity from the Town of Rossville and buys water from Collierville. City Manager Steinbach told the board this was a deliberate choice to stay out of the water and sewer business. The deal dates to 2015. Rossville has a 2.5 million gallon lagoon, oversized for a town of fewer than 1,600 residents because it was built with Kellogg's in mind. That spare capacity let Piperton keep growing through neighborhoods like Ridgewood Grove, Greenbrier, Twin Lakes, and Shaw's Creek on Raleigh LaGrange.
Piperton's allocation under that deal is 80,000 gallons a day. On April 16, 2026, Rossville proposed raising it to 400,000 gallons a day. The terms included an $800,000 annual reserve capacity fee plus higher rates per thousand gallons. Steinbach recommended against accepting, noting that ten years of the fee would cover the cost of a treatment plant of Piperton's own. He also said he understood Rossville's wish to save capacity for its own growth.
Piperton's other option is a treatment plant it already owns. The Adair plant was built but never finished and has been mothballed. Renovating it was estimated at $8 to $9 million. Steinbach said servicing that debt would mean raising rates more than 100% for the city's small customer base. So the board approved up to $10,000 for Wauford & Company Consulting Engineers to study a lagoon instead. That route still needs TDEC approval, which a city staffer called "a steep hill to climb."
Flows are already close to the limit. In the February 2026 reporting period, Piperton reached 97.21% of its Rossville allowance. The city blamed water use during the snow event, so treat that as a weather-driven peak, not a normal month.
Meanwhile construction hasn't stopped. In May 2026, Piperton reported 69 homes under construction and eight new-home permits. Projects on the books include:
- Prestonwood: a five-phase planned development of about 82.75 acres with 237 proposed lots. The rezoning was approved, and Phase 1 adds 55 lots.
- Piper Hollow Phases 3 and 4: 20 lots and 19 lots, both given preliminary plat approval for Arbor View Investments in July 2026.
- Shaws Creek Phase 3: developer John Duke asked to rescind the development contract, and the city budgeted a refund of development fees.
Every one of those lots needs the sewer problem solved. That's why the city manager tied his two-year estimate directly to "the development proposals... on the table now."
Oakland has 4,000 approved lots and plans for fewer homes
Twenty minutes north, Oakland's treatment plant isn't the constraint. The town expanded it from 1 to 3 million gallons a day in a $28.8 million project. The town's wastewater page now lists 3 MGD of capacity against an average flow of about 1 MGD. July 2026 board minutes describe the project as signed off by state inspectors and more than 90% complete.
Oakland's problem is everything between that plant and a buildable lot. At the May 5, 2026 Planning Commission meeting, the town's planner said Oakland has about 4,000 vested lots and "no comprehensive plan to provide sufficient infrastructure to all the approved subdivisions." He estimated about a third of those lots won't be developed because the infrastructure they need isn't readily available.
On July 16, 2026, the Board of Mayor and Aldermen voted unanimously for Resolution 26-43. Until the town finishes a full review of infrastructure capacity, it won't support residential rezonings that allow lots smaller than the R-1 minimum of 15,000 square feet. Planned Developments can still be considered if they show strong site design and pay for adequate infrastructure. Vested lots, approved plats, and existing zoning aren't affected. The resolution names water distribution, sanitary sewer, roads, and stormwater among the systems those 4,000 lots will strain.
Put the two together. Oakland's near-term new homes will come almost entirely from lots already approved, and the town expects a meaningful share of those never to be built. Any new subdivision approved by rezoning outside a Planned Development will start at 15,000 square feet per lot.
Oakland's largest active subdivisions release lots as homes sell. Riverwood Gardens, for example, is a 468-lot subdivision whose phases go to D.R. Horton. The developer says future phases depend on how fast homes sell. Phase 7, with 55 lots, was forecast to finish in August 2026. We couldn't confirm whether it did.
The deed data shows the supply squeeze
The Memphis Area Association of Realtors tracks Fayette County deed sales. The August 2026 report shows how the year has gone through August:
| Fayette County, Jan–Aug | 2025 | 2026 | Change |
|---|---|---|---|
| New-home sales | 166 | 136 | -18.1% |
| New-home median price | $384,445 | $387,845 | +0.9% |
| Existing-home sales | 397 | 407 | +2.5% |
| Existing-home median price | $335,000 | $360,000 | +7.5% |
| All sales | 563 | 543 | -3.6% |
The key number is the gap between the two medians. Through August 2025, the median new home sold for about $49,400 more than the median resale. Through August 2026, the gap was about $27,800. New-home prices held flat while new-home sales fell. Resales picked up some of that demand, and their prices rose.
Use the year-to-date figures, because single months swing hard here. In July 2026, Fayette County total sales were down 31.4% from a year earlier. In August they were up 25.8%, and the August new-home median of $348,445 was down 8.3%. One month can reflect which subdivisions happened to close. Eight months makes the pattern clearer.
New construction hasn't collapsed. Census permit data shows Fayette County authorized 356 housing units in 2025, up from 225 in 2024. That count covers every structure type and doesn't track closings, but it fits what the town minutes describe. Building continues inside subdivisions that already have approvals and utilities. At Piperton's September 2025 board meeting, the mayor noted dirt work at Piperton Hills Phase 2, and staff said crews were laying base and grading lots at Lakes of Greenbrier Phases 3 and 4. City Manager Steinbach said several developers were looking at residential projects and that the city had discussed impact fees and infrastructure cost sharing with its Planning Commission. Who pays for infrastructure was already part of the conversation about any new project.
Where BlueOval City fits
Early talk about Fayette County housing assumed Ford would set the pace. In 2022, homebuilders and investors were watching the small towns around the megasite. Oakland was already among the faster-growing towns in the region, though, and that growth started well before Ford's announcement.
The plant's schedule has kept moving. According to Tennessee Lookout's July 2026 status report, BlueOval City still isn't producing, five years after the announcement and despite an original 2025 target. Ford dropped its electric pickup at the site and now plans gas-powered Built Ford Tough trucks at the renamed Tennessee Truck Plant starting in 2029. SK On Tennessee, which took full ownership of the battery plant in May, plans production from 2028. Both companies say they'll still meet the 5,800-job commitment, with hiring ramping up closer to production. Fayette County's population grew 2.2% from 2022 to 2024, short of the state's projections for counties around the site.
No local official or reporter we found has connected the 2026 drop in new-home sales to Ford's timeline. What the public record does show is a list of tighter local constraints: Piperton's sewer contract, Oakland's infrastructure gap, and a minimum lot size for new rezonings. If Ford hiring picks up toward 2029, it will run into the same constraints.
What to ask before you choose a new build
Here's how these constraints show up in a purchase:
- Which sewer system serves this lot, and how much capacity is left? In Piperton, this decides whether later phases happen on schedule. A subdivision where you're buying an early phase may depend on capacity the city hasn't secured yet.
- Is this phase on a recorded, vested plat? Oakland's resolution protects vested lots. Lots that still need rezoning face the 15,000-square-foot minimum or a Planned Development review.
- What does the builder say about later phases? When phases are released as homes sell, the street you buy on may look finished for a while, or it may stay under construction longer than you'd expect.
- How does the resale down the road compare? With the year-to-date gap near $28,000 through August 2026, an existing home in Oakland or Somerville with a larger lot and established landscaping is a closer comparison than it was a year ago.
- Could utility rates change? Piperton's own analysis puts the cost of financing new treatment on ratepayers. Ask what the current rate is and what decisions are pending.
Quick answers
Is Oakland under a building moratorium? No. Resolution 26-43 is a policy against approving smaller-lot rezonings, and it doesn't touch vested lots. Oakland's separate moratorium covers only mobile homes and mobile home parks, and it's been extended through February 2027.
Has Piperton stopped issuing permits? No. It reported eight new-home permits and 69 homes under construction in May 2026. The sewer deadline affects how fast future phases can move.
Are the MAAR days-on-market figures specific to Fayette County? The 56 average days on market and 5,056 active listings in MAAR's August 2026 release cover the whole MAAR region, not Fayette County alone.
