Olympia, WA Population Trends and Real Estate Impact in 2026
Olympia, WA sits at roughly 56,000 residents spread across 18.2 square miles. Being the state capital brings a certain baseline of stability across all Olympia, WA zip codes, and the city has been growing steadily for over a decade - that growth has a very direct effect on what it costs to buy here and how fast you need to move when something hits the market.
If you're shopping for a home in Olympia, the demographic picture isn't just background noise. It explains why listings disappear quickly and why the numbers keep trending in one direction.
Current Population Size and Growth Rates
The US Census Bureau and the American Community Survey put Olympia's population somewhere between 55,951 and 56,271 people. Back in 2010, the city was closer to 47,000 - so the 18.1% increase over that decade wasn't subtle. From 2010 through 2024, the overall growth rate reached 19.6%, which works out to roughly 1.4% per year on average.
That's not explosive by some standards, but it's been consistent. And consistent population growth, when it keeps outpacing what's being built, is exactly what squeezes a housing market. As Thurston County keeps attracting new households, the pressure on local services and available homes doesn't let up.
Local authorities have laid out a 25-year growth target to account for all of this. The problem is that current building rates aren't keeping pace with the people arriving. That gap between population and supply is the single most important thing to understand about buying here right now.
How More Residents Affect the Housing Market
The median sale price in Olympia is sitting around $554,698, and homes are spending roughly 12 days on the market before going under contract. That's not a lot of time to think it over.
The city has been permitting an average of 370 new housing units per year over the last five years. According to municipal reports, that only covers about 60% of the housing needed to keep up with long-term growth targets. With roughly 2.5 months of supply available, you're not shopping in a buyer's market.
Buyer Demand and Local Inventory
Just over a third of homes in Olympia sell above their initial list price, and there are often fewer than 130 active listings across the entire city at any given time. When you find something that works for your budget, hesitation is expensive - the average sale-to-list ratio sits just over 100%, which tells you sellers are generally getting their full asking price.
Competing offers aren't an occasional surprise here. They're a regular part of the process.
New Construction and Planned Developments
Developers are working to close the supply gap, and there's real activity happening. Thurston County permitted 1,049 multifamily units in 2025, which made up 55% of all homes permitted that year. At the city level, Olympia approved a permit fee grant program in May 2025 specifically to support affordable housing projects.
Two projects worth knowing about: West Bay Yards is a planned development that would bring 478 market-rate rental units alongside retail and recreation space. On the single-family side, the city is reviewing plans for Green Cove Park, which would subdivide 50 acres into 181 residential lots. These are in the pipeline, not finished product - but they signal where density is headed.
Population Density and Infrastructure
Olympia's population density runs between 2,900 and 3,070 people per square mile, and keeping up with that concentration takes real infrastructure investment. The city's 2025-2030 Capital Facilities Plan allocates $8.3 million for wastewater upgrades, including work on the Old Port 1 and Miller and Ann lift stations.
Roads and transit are being updated too. The Fones Road Corridor improvement project is underway now, with construction scheduled to wrap in 2026. Downtown, the 4th Avenue Sewer Upgrades and ADA improvements are tackling aging pipes while updating sidewalks at the same time.
On the alternative transportation side, a new Westside Corridor bike route is planned for 2026 to connect northwest and southwest Olympia to Woodruff Park and Garfield Elementary. The State and Pacific Avenue Pedestrian and Bike Safety Project runs alongside that effort. None of this is glamorous, but it matters - infrastructure investment in a growing city is what keeps daily life functional as the headcount climbs.
Frequently Asked Questions
Is the population growth in Olympia, WA driving up local housing prices?
Yes. More residents, not enough homes to go around - that's the short version. With only about 2.5 months of inventory available, the median sale price is holding strong at approximately $554,698, and buyers are routinely paying at or slightly above asking price.
Which Olympia neighborhoods are seeing the most new residential development to handle population growth?
Development is spread across a few areas. The planned West Bay Yards project would add 478 rental units, and Green Cove Park is working through approvals to bring 181 single-family lots to market.
Are local infrastructure and school systems in Olympia keeping up with the recent influx of new residents?
The city is actively investing in infrastructure. The Fones Road Corridor improvements are underway, a new Westside Corridor bike route connecting to Garfield Elementary is planned for 2026, and the 2025-2030 Capital Facilities Plan dedicates $8.3 million to wastewater upgrades.
What is the projected population growth for Olympia over the next decade, and is it a good time to buy investment property?
Specific numerical projections for the next decade vary, but the city's own figures show that 370 new housing permits per year - the current average - only meets about 60% of long-term growth targets. That ongoing shortfall suggests demand for residential property isn't going anywhere.
