Donaldsonville's First New Subdivisions in Decades Are Arriving Ahead of the Steel Mill

November 12, 2026

The Advocate reports that nobody has built a new subdivision on the west bank of Ascension Parish in decades. Two are now moving through Donaldsonville City Hall. Both arrive as the RiverPlex Mega Park near Modeste prepares for two of the largest industrial builds in the region. The Advocate notes that the Hyundai steel mill's construction, permanent and indirect jobs together outnumber Donaldsonville's 2025 Census population estimate of 7,094.

That comparison makes a housing boom sound certain. But most of those jobs belong to construction crews who will be here for a few years, and Donaldsonville has written rules meant to house them outside the permanent market. For a buyer, seller or investor weighing the west bank, the timing of each wave of workers tells you more than the total does.

A Temporary Housing Site Can Go in Any Zoning District

Start with the friction most likely to surprise a buyer. Under the temporary workforce housing ordinance the Donaldsonville City Council passed this fall, temporary worker housing is allowed in any zoning district, as long as the council approves a permit. The Advocate's report on the ordinance lays out the main conditions:

  • The City Council approves each permit after a public hearing.
  • Notice runs in the official journal and is mailed to property owners within 300 feet of a proposed site.
  • A permit lasts 12 months at most. Extensions come in increments of up to six months, and no permit can run longer than three years.
  • Each site must hold at least 20 units. City Attorney Spencer Long said that keeps someone from putting "three temporary units" on a vacant lot around the corner.
  • The council may require shuttles, loading areas or other steps to limit traffic.
  • Applicants must submit a site plan and a plan for decommissioning, removal and restoration. Afterward the land goes back to whatever its zoning allows.

If you're buying a home in the city, the base zoning on the lots near you won't by itself tell you what could sit next door for up to three years. The 300-foot mailed notice is the warning system. Sellers should know that the same notice can reach a buyer mid-contract.

Mayor Leroy Sullivan has been clear that he does not want anything that looks like a "man camp" of modular buildings, trailers or shipping containers. He told The Advocate he would ideally like land used for temporary housing to become permanent subdivisions:

"My only concern is to make sure that whatever is done, when all of the industry is over, is that we're not left with a bunch of houses that are abandoned."

That goal shapes everything else in this post. The city wants the construction surge to leave behind infrastructure, not empty buildings.

The Workers Arrive in Waves, Years Apart

The headline job counts mix together workers who will be here on very different schedules.

Project Jobs reported Timing reported
CF Industries ammonia plant, $3.7 billion About 3,900 construction jobs Broke ground in August 2026; jobs spread over about four years
Hyundai-POSCO steel mill, $5.8 billion About 4,800 construction jobs at peak Ceremonial groundbreaking Sept. 4, 2026
Hyundai-POSCO steel mill, permanent About 1,300 direct jobs averaging $95,000 a year, plus an estimated 4,100 indirect jobs Mill completion anticipated in 2029

The first wave is the largest and the shortest-lived. WAFB reported that site preparation had begun at the September groundbreaking, but above-ground plant construction needed an air permit first. WBRZ reported on Oct. 28 that the Louisiana Department of Environmental Quality had approved that permit. The Advocate reports that the permit runs until Oct. 23, 2031.

Construction crews mostly need short-term places to sleep. The temporary housing ordinance exists for exactly that demand. Planning and Zoning Commission Chairman Carl Capone told The Advocate he had been talking with a West Virginia-based developer about a possible project of 400 to 1,200 units of about 900 square feet, each built for one or two people. He described the idea as land that could later become a subdivision because the water, gas and roads would already be in. That was a discussion at a commission meeting, not an application. It still shows how the city expects things to unfold. The construction wave pays for infrastructure, and the permanent wave inherits it.

The permanent wave is the one that buys houses, and the mill isn't expected to be complete until 2029. That gives Donaldsonville's for-sale market a few years to grow into the demand.

What the For-Sale Pipeline Actually Holds

Two subdivisions make up the visible permanent pipeline. On the numbers reported so far, they are modest in size and mostly at starter prices.

Cane Field Crossing is a roughly 46-acre development on Thibaut Drive from J. Breaux Enterprises, a Carencro-based company. The Donaldsonville City Council approved its development agreement, which lets the developer move on to preliminary plats and drainage and traffic studies. The Advocate reports about 130 single-family homes priced between $250,000 and $280,000. Most will be three-bedroom, two-bath, with some four-bedroom, two-and-a-half-bath plans. The developer agreed to install natural gas throughout, and Mayor Sullivan said the city will hook the gas up to the homes. The preliminary plat, filed for J. Breaux Enterprises by Quality Engineering & Surveying, was on the Planning and Zoning Commission's Nov. 2 agenda, according to the Pelican Post.

The Loop 945 subdivision is a proposed 187-lot project from Lyn Levy Land Company, a Baton Rouge-based developer. It sits on nearly 52 acres the council moved to rezone from commercial to residential. Final approval was set for Sept. 22, and WBRZ reported that the council unanimously approved a 52-acre rezoning that night. The developer has already finished its preliminary plat and its traffic and drainage studies. Lots are expected to be about 50 feet wide and 120 to 140 feet deep. No home prices or square footage have been provided.

Together that's roughly 317 homes against about 1,300 permanent mill jobs, before counting indirect jobs. The gap explains why officials keep returning to the idea of turning temporary sites into subdivisions later. Parish planners are thinking the same way. The Donaldsonville Chief described the draft West Bank Resilient Community Overlay as a plan to guide development, encourage housing in selected areas, account for a proposed Highway 3127 extension and preserve rural areas.

The roads are getting money as well. The Advocate's reporting on the Hyundai agreements lists about $66 million for roads supporting La. 1, $20 million for a connector from La. 405 to RiverPlex and $146 million for a rail overpass. These projects change which parts of the west bank are easy to reach from the plant gates. Over time, that affects which streets new subdivisions choose.

Ascension's September Numbers Show a Patient Market

If industrial news alone pushed prices up, the parish data would show it already. It doesn't. In September 2026, the Greater Baton Rouge Association of REALTORS® market report for Ascension Parish recorded:

  • 129 closed sales, up 15.2 percent from September 2025
  • A median sale price of $295,000, down 1.7 percent
  • 64 days on market, up 42.2 percent
  • 484 homes for sale, about four months of supply
  • 95 pending sales, down 15.2 percent
  • A year-to-date median of $314,065 through September, up 1.3 percent

Two readings follow. Homes are taking noticeably longer to sell and pending sales fell, so the parish heading into fall looks balanced, not overheated. Most of those sales are also on the east bank, in Gonzales, Prairieville and the communities around them. Donaldsonville's own market is small enough that parish figures can only frame it.

Cane Field Crossing's announced $250,000 to $280,000 range sits below the September parish median of $295,000. In practice, the first new west-bank construction in decades is aimed at entry-level and first-move buyers, many of whom may be weighing it against older resale homes in town and new construction across the river.

Questions to Settle Before Buying or Selling on the West Bank

  1. Is anything planned within 300 feet? Because temporary worker housing can be permitted in any zoning district, check the City Council's public hearing notices for parcels near the home you're considering.
  2. Which wave are you counting on? A rental investor betting on construction crews faces permitted temporary sites built for that demand. A buyer or seller looking to the permanent workforce is looking at a timeline tied to the mill's anticipated 2029 completion.
  3. How does the home compare with the new construction? A resale home priced near Cane Field Crossing's range is competing against new three-bedroom homes with natural gas service.
  4. How far is the commute to RiverPlex? The La. 405 connector and La. 1 road work are funded through the Hyundai agreements. A proposed Highway 3127 extension is part of the parish's west bank planning.
