California Is Building Up: What Walnut Creek’s New 104-Home Project Says About the Future of Housing
For years, California's housing debate has centered around one question:
Where are we supposed to put all these homes?
Walnut Creek may have just given us one answer.
A former auto-repair property at 1532 Mt. Diablo Boulevard in downtown Walnut Creek has been approved for redevelopment into an eight-story mixed-use building with 104 homes, including 14 affordable units.
The project would also include roughly 8,400 square feet of retail space and just 49 parking spaces.
Why so little parking?
Because it's being built in downtown Walnut Creek, near BART.
An old commercial property designed around automobiles could eventually become housing designed around people.
That's a pretty good snapshot of what's happening across California.
From Auto Repair Shop to 104 Homes
For decades, California cities were largely designed around the automobile.
We built:
Wide roads.
Parking lots.
Gas stations.
Shopping centers.
Low-rise commercial buildings.
And enormous amounts of parking.
That made sense during an era when California still had plenty of room to expand outward.
But California's major coastal metropolitan areas don't have unlimited land anymore.
And some of the most desirable places to live are also the places where housing is hardest to build.
That means communities increasingly have to look at the land they already have.
In Walnut Creek, that means asking a pretty interesting question:
Is an auto-repair property in the middle of downtown still the highest and best use of that land?
Developers believe the answer is no.
Instead, the property could eventually support more than 100 households.
The Numbers Behind the Walnut Creek Project
The proposed development is significant for a relatively small downtown site:
104 total homes
14 affordable units
8 stories
Approximately 8,400 square feet of retail
49 parking spaces
Near BART and downtown Walnut Creek
But one of the most interesting parts of the story isn't the number of apartments.
It's the height.
The project is taller than Walnut Creek had historically envisioned for that location.
So how did it happen?
California Housing Law Is Changing Local Development
For generations, California cities had enormous control over what could be built inside their borders.
Cities determined zoning.
They established height limits.
They controlled density.
And major developments could spend years moving through hearings, appeals and political battles.
That system is changing.
California has passed numerous housing laws intended to make it harder for local governments to block housing that complies with state requirements.
Affordable housing can also allow qualifying developments to receive incentives or concessions from certain local development standards.
That's important in Walnut Creek.
The approved project includes affordable housing, which helps allow the development to exceed local height restrictions.
According to reporting by the San Francisco Chronicle, the project can also proceed without a traditional City Council review or appeal process.
In other words:
California housing law changed the math.
Walnut Creek Is Being Asked to Build Thousands of Homes
There's a larger reason projects like this are appearing.
California assigns housing-production targets to regions and local governments through the Regional Housing Needs Allocation process, commonly called RHNA.
Walnut Creek's housing allocation increased substantially for the current planning cycle.
Its prior housing element planned for approximately 2,235 homes.
The current cycle calls for capacity to accommodate approximately 5,805 homes.
That doesn't mean the state personally builds those homes.
Instead, communities have to create zoning and planning frameworks that provide realistic opportunities for housing to be developed.
And once you start looking around an established community like Walnut Creek, the challenge becomes obvious.
Where do 5,805 additional homes go?
You probably aren't bulldozing thousands of existing single-family houses.
There isn't endless vacant land sitting next to downtown.
So cities increasingly look toward:
Commercial corridors.
Underutilized shopping centers.
Parking lots.
Older office properties.
Transit corridors.
And lower-density commercial sites.
That's why this former auto-repair property matters.
It's a small example of a much larger transformation.
Is This California's New Starter Home?
When Californians picture homeownership, many still picture the traditional California house.
Three bedrooms.
Two bathrooms.
Garage.
Driveway.
Backyard.
Maybe a basketball hoop out front.
There's nothing wrong with wanting that.
The problem is that in many California communities, the land underneath that house has become extraordinarily expensive.
So the next generation of California starter housing may look different.
It might be:
A condominium.
A townhome.
A smaller apartment-style condominium near transit.
A duplex.
An ADU.
A mixed-use development with shops downstairs.
Or a home where the household owns less land but gains easier access to restaurants, jobs and transportation.
That isn't necessarily worse.
It's simply a different version of California living.
The Parking Number Is Almost as Interesting as the Housing Number
The Walnut Creek project reportedly proposes only 49 parking spaces for 104 homes.
Twenty years ago, that probably would have sounded crazy in many California suburbs.
Today, it's increasingly intentional.
Building structured parking is expensive.
Land dedicated to parking cannot simultaneously become housing.
And properties located near major transit systems theoretically allow some residents to own fewer vehicles.
Walnut Creek BART connects residents to Oakland, San Francisco and other employment centers throughout the Bay Area.
That doesn't mean everyone living there will abandon their car.
This is California, after all.
But the project reflects a broader planning philosophy:
If we're going to build more housing, put some of it where people have alternatives to driving everywhere.
Why Build Housing on Commercial Land?
Converting or redeveloping commercial property has another advantage.
It can add housing without necessarily replacing an existing neighborhood of homes.
Imagine the choices.
Option one:
Increase density inside established single-family neighborhoods.
Option two:
Keep those neighborhoods largely intact while adding significant housing along commercial and transit corridors.
Most California communities will probably end up doing some combination of both.
But converting underused commercial land can sometimes be the less disruptive option.
A parking lot doesn't have to move.
An old commercial building doesn't have children attending the neighborhood school.
An obsolete office property doesn't have a family that needs to be displaced.
That makes commercial redevelopment one of the more interesting pieces of California's housing puzzle.
But More Housing Doesn't Automatically Mean Affordable Housing
This distinction matters.
Building more housing and building affordable housing are related concepts, but they're not identical.
Most of the 104 units in the Walnut Creek project would be market-rate housing.
Fourteen are designated affordable.
Critics of new development sometimes argue that market-rate housing doesn't solve affordability because the new units themselves may still be expensive.
That's understandable.
But housing supply works across an entire market.
When households have more options, there is less pressure on the existing housing stock than there would be if those homes were never built.
That doesn't mean one 104-unit development fixes Bay Area housing affordability.
Of course it doesn't.
But California didn't develop its housing shortage because one project wasn't built.
It developed over decades of building fewer homes than growing communities needed.
The solution will likely work the same way in reverse:
One project at a time.
What Does This Mean for Existing Homeowners?
More housing doesn't automatically destroy the value of existing homes either.
In fact, desirable communities usually remain desirable because people want to live there.
Adding residents near downtown can potentially support:
Restaurants.
Coffee shops.
Retail.
Transit.
Local businesses.
Walkability.
Public amenities.
And a more active downtown.
The challenge is balancing that growth with infrastructure, schools, traffic, utilities and the character residents value.
Those are legitimate concerns.
Housing policy doesn't become useful by pretending tradeoffs don't exist.
The real question is whether California can accommodate growth without allowing housing costs to push an increasing share of its population away.
The Bay Area Is Changing Again
The Bay Area has reinvented itself repeatedly.
Agricultural land became suburbs.
Industrial neighborhoods became residential neighborhoods.
Warehouses became offices.
Office districts became technology centers.
And now some commercial properties may become housing.
Walnut Creek's proposed transformation from an auto-repair property into more than 100 homes is part of that evolution.
The interesting thing isn't whether everyone personally wants to live in an eight-story building.
Some people absolutely don't.
The interesting question is whether communities can offer multiple versions of the California dream.
Some people want the detached house.
Some want the condo downtown.
Some want the ADU.
Some want the townhouse.
Some want to walk to BART.
Some want enough land that they can't see their neighbor.
A functioning housing market probably needs all of them.
California Can't Create More Land
That's ultimately what makes this story important.
California can't manufacture another Bay Area.
We can't create another Orange County coastline.
We can't move Silicon Valley somewhere with unlimited land.
But we can change how efficiently we use the land we already have.
Sometimes that means building an ADU behind an existing house.
Sometimes it means replacing a parking lot.
Sometimes it means building condos instead of another commercial building.
And sometimes it means looking at an old auto-repair property in downtown Walnut Creek and realizing:
104 families could live here instead.
Whether that sounds exciting or terrifying probably tells you a lot about where you stand in California's housing debate.
But one thing is becoming increasingly clear:
California's next generation of housing probably won't look exactly like the last one.
And maybe it shouldn't.
Thinking About Buying in the Bay Area?
Buying in today's Bay Area market isn't simply about finding the lowest advertised mortgage rate.
Property type matters.
HOA structure matters.
Condo eligibility matters.
Down payment matters.
Insurance matters.
And the complete monthly payment matters.
Our team works with first-time buyers, conventional and jumbo borrowers, FHA and VA buyers, condos, non-warrantable condominiums, TIC financing and other scenarios throughout the Bay Area and California.
The goal isn't to convince someone to buy before they're ready.
It's to understand the numbers well enough to know when an opportunity actually makes sense.
