Placer And Yuba Lead California In Growth, And In New Housing

Population growth in Yuba and Placer County led California in 2025, but housing grew faster. See the state's figures for Yuba, Sutter, Butte and Placer rentals.

California as a whole lost a few residents last year. The four counties covered here did not. If you own a rental home in Roseville, Lincoln, Plumas Lake or Yuba City, the state's newest estimates are worth ten minutes of your time, because population growth in Yuba and Placer County was the fastest in California in 2025, and the number of homes grew even faster.

Both halves of that sentence matter. More residents can mean more people looking for a place to rent. More homes can mean more listings competing with yours. Here is what the figures say and how to use them.

How fast are Yuba, Sutter, Butte and Placer counties growing?

According to the California Department of Finance's estimates released May 1, 2026, Placer County grew 1.39 percent in 2025, the fastest rate of California's 58 counties, and Yuba County was second at 1.24 percent. The state as a whole slipped 0.14 percent, to about 39,593,000 people, and only 17 counties gained residents.

The Department of Finance's January 1, 2026 estimates for the four counties:

• Placer County: 434,823 residents, up 1.4 percent from 428,880 a year earlier.
• Yuba County: 87,692 residents, up 1.2 percent from 86,620.
• Sutter County: 101,679 residents, up 0.4 percent from 101,270. That was the eighth-fastest growth rate among California counties.
• Butte County: 208,941 residents, up 0.2 percent from 208,597.

The Department of Finance labels its newest January figures preliminary and revises earlier years as better data comes in, so treat them as estimates and not a head count.

Which local cities added the most residents?

Roseville added more residents than any other California city under 300,000 people. The Department of Finance estimates Roseville at 165,455 residents on January 1, 2026, up 4,293 in one year, or 2.7 percent. Growth elsewhere in Yuba-Sutter, Butte and Placer County was uneven, and several cities were close to flat.

The state's January 1, 2026 city estimates:

• Lincoln: 56,494, up 1.9 percent.
• Rocklin: 74,842, up 0.5 percent.
• Loomis: 6,822, essentially unchanged.
• Yuba City: 71,572, up 0.5 percent.
• Live Oak: 9,755, up 0.1 percent.
• Wheatland: 4,140, up 2.3 percent.
• Marysville: 12,679, down 0.4 percent.
• Chico: 108,113, up 0.1 percent.
• Paradise: 10,581, up 9.2 percent, which the Department of Finance attributes to housing production.

Most of Yuba County's gain came outside its two cities. The unincorporated part of Yuba County, everything outside Marysville and Wheatland, grew 1.5 percent to 70,873 residents.

Is new housing keeping up with population growth in Yuba and Placer County?

Yes, and in 2025 housing grew faster than population in both counties. The Department of Finance reports that Yuba County's housing stock grew 2.32 percent, the highest rate of any California county, to 32,770 homes. Placer County's grew 1.9 percent, to 191,225 homes, fourth highest in the state.

A few details behind those totals, from the same Department of Finance report:

• Roseville added 2,106 housing units in 2025, the sixth-largest gain of any California city, and 1,151 of them were single-family homes.
• Lincoln's housing stock grew 2.5 percent, to 23,033 homes.
• Unincorporated Yuba County's housing stock grew 2.8 percent, to 26,083 homes.
• Sutter County's housing stock grew 0.3 percent and Butte County's 0.9 percent.

For a rental owner, this is the part of the report that gets overlooked. When a county adds homes faster than it adds people, renters have more to choose from. A newly built house a mile away, offered for rent by its first owner, is direct competition for an older home. Our earlier post on what keeps renters coming to Yuba City and Marysville covers the demand side; the supply side deserves equal attention.

Where is the growth in Placer, Yuba and Sutter County coming from?

In Placer County, growth comes almost entirely from people moving in. The Department of Finance's county estimates for the year ending July 1, 2025 show Placer County gaining 5,323 residents, of which 4,968 came from net migration and 355 from births exceeding deaths. Yuba and Sutter counties drew on both sources.

The same state table, for July 1, 2024 to July 1, 2025:

• Yuba County: up 1,033 residents, with 413 from natural increase and 620 from net migration.
• Sutter County: up 573 residents, with 258 from natural increase and 315 from net migration.
• Butte County: down 114 residents. Deaths exceeded births by 315, which outweighed net migration of 201.

These mid-year figures cover a different twelve months than the January estimates above, which is why the totals don't match exactly. The practical point is that Placer County's demand depends heavily on people continuing to relocate there, while Yuba and Sutter counties have a steadier base of natural increase underneath.

Can a landlord raise the rent more because the county is growing?

No. Population growth doesn't change California's rent limits. Under Civil Code 1947.12, part of the Tenant Protection Act, an owner of a covered rental generally can't raise the rent over any 12-month period by more than 5 percent plus the percentage change in the cost of living, or 10 percent, whichever is lower.

Three points from Civil Code 1947.12 that matter in a growing area:

• Newer homes. Housing issued a certificate of occupancy within the previous 15 years is generally exempt from the cap, unless it is a mobilehome. Some homes in Plumas Lake, west Roseville and Lincoln are that new, but the exemption runs out as the home ages.
• Single-family homes and condos. A home that can be sold separately from any other unit can be exempt when the owner is not a corporation, a real estate investment trust or an LLC with a corporate member, and only if the tenants received the written notice the statute spells out.
• New tenancies. When a home turns over and no prior tenant remains, the owner sets the starting rent, and the cap applies to increases after that.

Any increase also needs proper written notice under Civil Code 827. Whether a particular home is covered depends on its facts, and an owner who collects more than the law allows can be liable to the tenant for the excess, so ask a California landlord-tenant attorney before relying on an exemption.

What should a rental owner do with these numbers?

Use population and housing estimates as background, and set rent from what similar homes nearby have actually leased for. County-wide growth says little about one street. A reasonable routine for an owner in Yuba-Sutter, Butte or Placer County:

1. Check the supply near you. Look at how many homes like yours are listed for rent within a few miles, including newly built ones.
2. Price from recent leases. Asking rents and county averages can mislead. Signed leases on comparable homes are the better guide.
3. Keep the home competitive. Where renters have newer options, condition, working appliances and prompt repairs matter more.
4. Value a good renewal. In a market adding homes, keeping a tenant who pays on time and cares for the property often costs less than a vacancy.
5. Screen every applicant the same way. Population data counts people; it says nothing about who should live in your home. According to the California Civil Rights Department, state fair housing law protects renters based on characteristics including race, national origin, familial status, disability and source of income, so apply one written set of criteria to everyone.

Questions Owners Ask About Local Growth Figures

How often does California update its population estimates?

The California Department of Finance produces city and county population estimates annually. The January 1, 2026 figures were released on May 1, 2026, and the Department revises prior years in each release.

Is Butte County growing or shrinking?

It depends on the twelve months measured. The Department of Finance shows Butte County up 0.2 percent for calendar year 2025 and down 114 residents for the year ending July 1, 2025. Either way, the county's population was close to flat.

Where can an owner look up the estimate for one city?

The California Department of Finance posts its E-1 report, with population and housing estimates for every California city and county, on its Demographics pages at dof.ca.gov. Each county's table lists its incorporated cities and one line for the unincorporated area.
