Danville, CA Population: 2026 Size, Growth, and What It Means for Homes

Danville's home prices are set less by population growth than by how rarely a settled town's homeowners sell. Only 141 homes of all types sold in the 90 days ending September 30, 2026.

Key Takeaway

Danville is a small, settled town of about 43,302 residents as of July 1, 2025 (Vintage 2025 Population Estimate), and that stability, not rapid growth, is what keeps houses scarce. Single-family homes had just 1.9 months of supply in the 90 days ending September 30, 2026. If you need more time to shop, townhouses and condos are the looser part of the market.

Who This Guide Is For

This guide is for anyone checking Danville's population to judge how big and how competitive the town is before deciding to buy or sell a home here.

Current Population Count in Danville, CA

The latest Census Bureau estimate puts Danville's population at 43,302 residents as of July 1, 2025. That is a slight dip from the 2020 Decennial Census count of 43,582. Legally, the municipality is the Town of Danville, in Contra Costa County. Annual estimates on Census QuickFacts are revised, so note the vintage year when you quote the figure.

The town holds roughly 16,004 housing units, so that quarter's sales were a tiny fraction of the stock. Buyers are chasing a very small pool of available homes.

Growth Trends and Housing Supply

Danville's population grows slowly. The town grew from 42,039 residents in 2010 to 43,582 in 2020. The California Department of Finance then estimated a slight dip to 43,190 (provisional) by January 1, 2026. The slow pace is tied to limited developable land and General Plan buildout limits.

With an 85.5% owner-occupied rate, new supply mostly comes from existing owners deciding to sell, not from large new subdivisions. The town's 2023-2031 Housing Element plans for a minimum of 2,241 new units to meet state mandates, but large-scale development remains limited.

Check the Town of Danville planning department's current project list before counting on any build timing for new construction.

How Population Size Affects Local Home Prices

Steady buyer demand meets a very small resale pool in Danville. Single-family homes recently had 1.9 months of supply, and 38.4% sold above the list price. Well-priced houses often draw multiple offers right away, so have your financing entirely settled before you tour anything.

For sellers, a correctly priced single-family house recently spent a median of 26 days on the market, so plan your selling timeline around a quick sale. Housing market trends shift month to month, so recheck these figures before you list or make an offer.

Choosing Between Single-Family Homes and Attached Units

Buyers face a clear choice: a detached house in the tightest segment, or an attached home with less competition. About 24.1% of townhouses (30 sales) sold above list price, well below the houses' share. Townhouses also had 2.3 months of supply, which gives you slightly more room to negotiate terms. Their median price per square foot was $652, compared with $703 for condos.

Attached homes come with monthly HOA dues that reduce your purchasing power. Before making an offer, ask the association for current monthly dues, planned special assessments and the latest reserve study.

Reading the Recent Condo Price Drop

Condos give you the most time to look and negotiate, with a median of 42 days on the market and 3.7 months of supply.

The median condo sale price fell 41.9% year over year (based on 11 condo sales). With a sample that small, the decline most likely reflects which specific units happened to sell rather than condos losing that much value. Don't use the citywide condo median to price an offer. Instead, ask for the last six to twelve months of sales in the specific complex.

Population Density and Daily Life in Town

Danville is a low-density community, with 2,410.8 people per square mile over 18.08 square miles of land in the 2020 Census. In practice, that means a town of mostly detached homes on residential streets, with attached homes making up a much smaller share of sales.

That spread-out layout shapes daily commutes and everyday living costs, so weigh both alongside the housing numbers.

If schools matter, confirm the attendance boundaries for a specific address with the San Ramon Valley Unified School District school locator, since boundaries can change.

Using These Market Numbers in Your Search

Start with property type. If a detached house is a must, the home-prices section shows how tight that segment is, so plan for heavy competition. If a townhouse or condo would work, the attached-homes section shows where supply is looser.

Next, decide how much new construction might widen your options. A built-out town adds few homes, so review the growth constraints above before waiting for new builds. Sellers should weigh the low days on market against their own timeline to move. A quieter, lower-density setting shapes the homes on offer, as the density section shows.

For example, a buyer who needs to move within 60 days might compare the tight house supply with the looser condo supply and realize that looking at attached homes buys them time.
