Port St. Lucie keeps growing because it pairs available land with a planned jobs corridor along I-95 and a steady pipeline of new construction. The city added an estimated 9,131 residents in one year and sits about 31% above its 2020 population base. Jobs are still catching up, so it's important to separate planned projects from operating ones.

Why Is Port St. Lucie Growing So Fast?

Port St. Lucie is growing because it has room to build, a planned employment corridor along Interstate 95, and a steady supply of new-construction homes. Census estimates reported by CBS 12 put the city's population at 268,062 on July 1, 2025, up an estimated 9,131 residents in one year.

Rankings shift depending on the year and the population cutoff, so I'll stick to what the numbers show and what they mean if you're buying or selling.

Key Takeaways

• Port St. Lucie's estimated population reached 268,062 on July 1, 2025, after adding about 9,131 residents, or roughly 2.8%, in a single year.

• The city's 2025 estimate is about 31% above its 2020 base, indicating sustained growth over five years rather than a one-year spike.

• Recent local market data shows a median sale price of $389,000, a median of 12 days on market, and 2,442 active listings. Buyers have choices, while well-priced homes can still move quickly.

• Southern Grove, an approximately 8,200-acre employment area within the broader Tradition region, is planned for more than 22,500 jobs. That figure represents potential capacity, not current employment.

• On October 13, 2026, City Council approved site plans tied to a Costco project and the first phase of a Tradition Entertainment District. Approval does not mean those businesses are open.

How Fast Has Port St. Lucie Grown Over the Last Five Years?

Port St. Lucie's 2025 population estimate is about 31% above its 2020 base, according to CBS 12 News, citing U.S. Census Bureau estimates. This is the most recent data I'd call reliable as of October 2026, and it covers 2020 to 2025. It is not a 2026 headcount.

The latest single-year figure is just as telling. The city added an estimated 9,131 residents between July 1, 2024, and July 1, 2025, a gain of about 2.8%, according to the same Census-based reporting. St. Lucie County passed 400,000 residents in that estimate, and Port St. Lucie accounted for most of the countywide increase.

How Big Is Port St. Lucie Now?

The City of Port St. Lucie describes itself as Florida's sixth-most-populous city, covering roughly 121 square miles. The city also says it is not fully built out and expects more population growth. That is a municipal expectation, not a Census forecast, but it helps explain why new communities continue to open.

Is All of That Growth Inside the City?

No, and this matters if you're comparing towns.

The Port St. Lucie metropolitan area, which includes St. Lucie and Martin counties, was estimated at 568,721 residents in 2025. That regional number includes Stuart and Palm City. It is not the population of Port St. Lucie itself, so don't let anyone use it to inflate the city's growth figures.

What Is Driving Growth in Port St. Lucie, Tradition, and Southern Grove?

Three things drive growth: available land, a jobs corridor positioned along I-95, and housing priced below much of the coast. The first two are the parts people tend to overlook.

Why Does the Southern Grove Jobs Corridor Matter?

The city describes Southern Grove as an approximately 8,200-acre economic development area within the broader Tradition region. It is planned to attract manufacturing, logistics, research, health care, office, hotel, retail, and warehousing activity. The city identifies potential capacity for more than 22,500 jobs.

Location is a big part of the plan. The corridor sits along I-95 between the Tradition Parkway and Becker Road interchanges. The city's proposed Economic Development Element connects this location with logistics, distribution, and manufacturing uses.

Infrastructure funding has followed. The city reports a $3 million Florida Job Growth Grant awarded in 2018, a $3.5 million grant awarded in 2021, and $5.53 million in American Rescue Plan Act funding for roadway and utility improvements. Those are historical awards, not 2026 spending.

Which Projects Are Planned, Approved, or Operating?

Here's where I slow people down. An announcement is not a paycheck. When I talk through a move to this area, I sort every project into one of four categories: planned, approved, under construction, or operating.

• Planned: The city's Southern Grove page lists an Amazon delivery station planned for about 200 full-time jobs, an Accel International manufacturing facility associated with 125 positions, and an OCULUS Surgical expansion associated with 50 high-wage jobs.

• Projected: The city also reports that a Costco distribution center acquired 192 acres and was expected to create about 500 jobs. Treat that as a projection that depends on development.

• Approved: On October 13, 2026, City Council approved site plans connected with a Costco project and the first phase of a Tradition Entertainment District with restaurants and retail. Approval does not mean those businesses are open.

So, are jobs keeping pace with population? The honest answer is that the planning is ambitious and the buildout is still in progress. If your move depends on a local job, verify the employer's status before you commit.

What Does Port St. Lucie's Growth Mean for Buyers and Sellers?

It means more inventory, more new construction to compare against, and a market where pricing and condition influence how quickly a home sells.

Recent local market data shows a median sale price of $389,000 in Port St. Lucie, a median of 12 days on market, 2,442 active listings, and 1,533 homes sold over roughly the last 90 days.

Those are area-level figures. Your home's value depends on its condition, street, build year, and timing.

How Does Port St. Lucie Compare With Nearby Treasure Coast Areas?

Here is an at-a-glance comparison for the areas I work in most.

Area	Median Sale Price	Median Days on Market
Port St. Lucie	$389,000	12
Tradition	$411,950	41
Palm City	$649,950	50
Jensen Beach	$485,000	50
Fort Pierce	$289,000	28

Source: Aggregated public listing data, trailing 90 days, as of October 2026.

Notice the spread. Port St. Lucie homes are moving at a median of 12 days, while Tradition sits at 41 days and Palm City at 50 days. A faster median usually points to a larger share of homes that are priced and prepared well for the market, although it can also reflect the mix of homes selling during that period.

What Should Buyers Weigh Besides the Purchase Price?

When you're comparing markets, insurance and property taxes matter as much as the sticker price. A lower list price in a fast-growing city can still produce a different monthly payment once you add your actual insurance quote and any community fees.

Run those numbers for the specific home, not the area average.

New construction is a big part of Port St. Lucie's story, and I break down how it works in my guide to new construction homes in Port St. Lucie. If you're curious about the age-restricted side of the boom, I cover that in my article about the 55+ construction boom in Port St. Lucie.

If you're comparing against South Florida, my Fort Lauderdale versus Port St. Lucie cost-of-living breakdown is a good place to start.

What Does Growth Mean If You're Selling?

It means buyers have plenty to choose from, with thousands of active listings across the area. Your home competes with new builds and other resale properties, so presentation and pricing strategy carry real weight.

I walk sellers through that comparison before we ever list, because the right number depends on your home and your street, not the citywide median.

I made this kind of move myself, selling a longtime family home and moving into a new-construction home in a gated Port St. Lucie community. The biggest surprise was how much easier the decisions became once I had a clear picture of what my home would actually net and what I was buying next.

Because I'm also a licensed Florida mortgage broker, I can look at both sides of that picture at once.

I also keep this in mind: Port St. Lucie's growth story is still unfolding. Approvals, openings, and hiring will keep changing the map, so a plan that makes sense today should be reviewed again before you sign anything.

Frequently Asked Questions About Port St. Lucie's Growth

How Many People Live in Port St. Lucie Now?

The newest city-level Census estimate puts Port St. Lucie at 268,062 residents as of July 1, 2025. That is the latest figure available in the source, so the current number may be higher given the city's growth. The city's own webpages may still round to 260,000, which is an older figure.

Is Port St. Lucie Still One of Florida's Fastest-Growing Cities in 2026?

The most recent data shows continued growth, with about 2.8% added between mid-2024 and mid-2025 and a population about 31% above its 2020 base.

Rankings change with each Census release, so I wouldn't rely on a single list. The direction of growth is clear, and the city says it anticipates more growth.

What Major Employers Are Coming to Port St. Lucie?

The city's Southern Grove page lists an Amazon delivery station with about 200 planned full-time jobs, Accel International with 125 positions, an OCULUS Surgical expansion associated with 50 high-wage jobs, and a Costco distribution center expected to create about 500 jobs.

These are project figures, not current employment totals. Check each project's status before relying on the expected jobs.

What Is Driving Development in Tradition and Southern Grove?

Available land and an I-95 location are major factors. Southern Grove is an approximately 8,200-acre area within the broader Tradition region, positioned between the Tradition Parkway and Becker Road interchanges.

The city has supported the area with state and federal infrastructure funding. On October 13, 2026, City Council approved site plans for a Costco project and the first phase of a Tradition Entertainment District.

How Does Port St. Lucie Compare With Stuart, Palm City, and the Rest of the Treasure Coast?

Port St. Lucie's median sale price of $389,000 is lower than Palm City's $649,950 and Jensen Beach's $485,000, and higher than Fort Pierce's $289,000, based on the source's recent local market data.

Port St. Lucie's median days on market, at 12, is also shorter than those two areas. The metropolitan area covering St. Lucie and Martin counties has about 568,721 residents, so regional growth should not be confused with the population of Port St. Lucie itself.

Ready to See How This Affects Your Move?

The core takeaway: Port St. Lucie's growth is real and sustained, but jobs, retail, and amenities arrive in stages. Your decision should follow what is open and built, not just what is announced.
