California Housing Market: Building More Homes, But Is It Enough?

California's housing market is a puzzle, and while we've seen a significant increase in new homes being built, it hasn't quite solved our affordability crisis. Even though the state's population hasn't grown much lately, the demand for housing continues to climb, largely due to shifting demographics and the fact that more people are forming smaller households.

California's Housing Market: Building More Homes, But Is It Enough?

It’s easy to look at the numbers and think we’re on the right track. Over the past six years, California has added a whopping 677,000 new housing units. Meanwhile, our population growth has been pretty tame, barely nudging up by about 39,000 people in the same timeframe. You’d think this would mean more empty buildings and prices dropping, right? Well, that's not exactly what's happening on the ground.

I’ve been following California’s housing scene for a while now, and what I’m seeing is that simply building more doesn't automatically mean relief for everyone. The Public Policy Institute of California (PPIC) has been doing some great analysis on this, and their findings echo what many of us feel: the problem is deeper than just the raw numbers of people moving in.

Vacancy Rates Aren't Skyrocketing

You'd assume that with so many new homes popping up and fewer new people arriving, the percentage of empty homes – the vacancy rate – would go up, giving people more options and driving down prices. But that hasn't been the case. In fact, for owner-occupied homes, the vacancy rate actually dropped from 1.2% to 0.8%. Rental vacancy rates have seen a slight bump, only going up by 0.2%.

Compared to the rest of the country, California’s vacancy rates are still quite low. The PPIC notes that the rental vacancy rate here was around 4.3% in 2024, while nationally it was closer to 5.9%. This tells me that these new homes are being snapped up pretty quickly, and the demand is still outstripping the supply.

So, What's Driving Demand If Not Population Growth?

This is where it gets really interesting, and a bit complex. The PPIC’s analysis highlights that changes in demographics are playing a bigger role than sheer population growth. The way people live is changing, and that’s creating demand for more housing units, even if the total number of people remains steady.

There are two main demographic shifts happening in California:

• Fewer Kids, More Adults: First, birth rates are continuing to fall. This means there are fewer households with children. Between 2019 and 2024, the number of households with children actually decreased by 82,000. On the flip side, households without children increased by a huge 722,000.
• An Aging Population: Second, California's population is getting older. As people age, especially those in their later years, they are more likely to live alone or with just one other person. With more seniors around, we're seeing more smaller households, and naturally, this creates a need for more, often smaller, housing units to accommodate them.

These changes mean that even if our population growth slows to a crawl or plateaus, California will still need a consistent flow of new housing simply to keep up with the way our households are forming and operating.

Housing Stress Isn't Going Away

This is the part that hits home for so many Californians. Even with higher average incomes, we continue to spend a much larger chunk of our money on housing than folks in most other states. The PPIC points out that an alarming 14% of homeowners in California spend more than half their income on housing, and a staggering 28% of renters are in the same boat.

These numbers are a clear sign that while we're building more, it’s not enough to make housing affordable for a large portion of the population. The cost of housing remains a huge burden, and it's a defining feature of life here.

A Glimmer of Hope: Young Adults Are Moving Out

Despite all the challenges, there is a positive trend emerging that gives me some cautious optimism. We're seeing a slight increase in household formation among young adults. For years, many young Californians have been stuck living with their parents, sharing apartments with many roommates, or even moving out of state because housing costs were just too high.

This small uptick in young adults establishing their own households is an early signal that, perhaps, the new housing being built might be starting to catch up, even just a little, with the demand from this group. It’s a tentative sign, but a welcome one.

The Big Picture: Progress, But a Long Way to Go

The story of California's housing market lately is definitely not a simple one. It's not as easy as saying “we're building enough” or “nothing is working.” We have made genuine progress in adding new housing supply, and that supply is being used.

However, as the PPIC's analysis suggests, the housing shortage in California is deep-seated. We're dealing with the consequences of decades of not building enough homes, and the compounding effect of rising costs just makes it harder.

Demographic shifts are going to keep the demand for housing strong. We need to keep building, and critically, we need to focus on building the right types of housing in the right places that will actually meet the changing needs of California's households. This isn't just about adding units; it's about smart, targeted construction that addresses the real housing challenges facing our communities. It remains a top priority, and one that requires continuous effort and innovative solutions.
