Parking Requirement Changes Explained
How California Is Reducing Parking Requirements to Increase Housing Production
Parking has long been one of the biggest hidden costs of residential development.
Most people don’t think about parking until they’re looking for a place to leave their car. Developers, however, know that parking requirements can determine whether a housing project is financially feasible.
Every required parking space takes up valuable land. Structured parking can cost tens of thousands of dollars per space to construct, while even surface parking reduces the area available for housing.
Recognizing this, California has adopted a series of laws that reduce or eliminate minimum parking requirements for many housing projects.
The goal is simple: make it easier—and less expensive—to build housing.
Why Does Parking Matter?
Local zoning ordinances have traditionally required a minimum number of parking spaces for new development.
For example, a city might require:
· Two parking spaces for every single-family home.
· Two spaces per apartment.
· Additional guest parking.
· Oversized drive aisles.
· Accessible parking.
· Bicycle parking.
While these requirements were intended to prevent parking shortages, they also increased development costs and reduced the number of homes that could be built on a property.
Why Is California Changing Parking Requirements?
State lawmakers concluded that parking requirements were limiting housing production in many communities.
Every required parking space:
· Increases construction costs.
· Reduces buildable area.
· Lowers residential density.
· Makes affordable housing more difficult to finance.
In many urban areas, California also found that residents living near public transit often own fewer vehicles than traditional parking standards assumed.
As a result, the Legislature has increasingly reduced mandatory parking requirements for qualifying housing projects.
Which Projects Benefit?
Several California housing laws now include parking reductions or eliminate parking requirements under specific circumstances.
Examples include:
· Accessory Dwelling Units (ADUs).
· Density Bonus projects.
· Transit-oriented housing.
· Certain affordable housing developments.
· Qualifying ministerial housing projects.
Each law has its own eligibility requirements, but together they reflect a clear statewide trend toward reducing parking as a barrier to housing.
Accessory Dwelling Units
One of the best-known examples involves ADUs.
Depending on the property’s location and circumstances, California law may prohibit local governments from requiring additional off-street parking for an ADU.
This has made many garage conversions and backyard cottages financially feasible where they might not have been under older parking regulations.
For many homeowners, eliminating the parking requirement removes one of the largest obstacles to adding a second dwelling unit.
Density Bonus and Parking
Parking reductions also play an important role in California’s Density Bonus Law.
Structured parking is expensive.
Reducing parking requirements can:
· Lower construction costs.
· Increase the number of housing units.
· Improve project feasibility.
· Make affordable housing financially achievable.
Sometimes the parking reduction is just as valuable as the additional density itself.
Transit-Oriented Development
California has also reduced parking requirements for many qualifying housing projects located near public transit.
The reasoning is straightforward.
If residents can:
· Walk.
· Ride a bicycle.
· Take a train.
· Use Bus Rapid Transit.
· Access employment without driving.
They may not require the same amount of parking traditionally expected in suburban communities.
Reducing parking requirements near transit encourages housing where transportation alternatives already exist.
Does This Mean Parking Is Gone?
No.
This is one of the biggest misconceptions.
California has reduced parking requirements for many qualifying projects.
It has not eliminated parking requirements everywhere.
Many projects still require parking based on:
· Local zoning.
· Building occupancy.
· Accessibility requirements.
· Fire access.
· Site design.
· Other applicable regulations.
Each project must be evaluated individually.
Why Investors Should Care
Parking directly affects project economics.
Reducing required parking may allow:
· More housing units.
· Lower construction costs.
· Smaller project sites.
· Greater return on investment.
· Improved project feasibility.
A property that seemed too small for development under older parking standards may now become a viable investment opportunity.
Rural California
Parking reform has a much different impact in rural communities.
Unlike dense urban areas, many rural residents rely almost entirely on personal vehicles.
As a result, developers often choose to provide parking even when state law allows fewer spaces.
In rural counties, factors such as:
· Septic system locations.
· Driveway access.
· Fire apparatus turnaround requirements.
· Topography.
often have a greater influence on site design than minimum parking requirements.
Common Misconceptions
“California eliminated parking requirements.”
False.
The State has reduced or eliminated parking requirements for certain qualifying projects—not for every development.
“Developers are prohibited from building parking.”
False.
Developers may still provide parking when it makes sense for the project or the market.
The laws generally reduce minimum required parking—they do not prohibit additional parking.
“This only applies to large apartment projects.”
False.
Parking reforms affect a variety of residential developments, including ADUs and many affordable housing projects.
“Parking doesn’t affect housing costs.”
False.
Parking can be one of the most expensive components of residential development, especially when structured parking is required.
Reducing unnecessary parking can significantly improve project feasibility.
Why This Matters
California’s parking reforms reflect a broader shift in housing policy.
Instead of applying the same parking standards to every project, regardless of location or circumstances, the State increasingly tailors parking requirements to the type of development being proposed.
Combined with:
· ADU legislation.
· Density Bonus.
· SB 79.
· Objective Design Standards.
· Permit Streamlining.
Parking reform is another tool designed to reduce unnecessary barriers to housing production.
The Bottom Line
Parking requirements may seem like a small detail, but they can have a major impact on whether a project succeeds.
For homeowners, reduced parking requirements can make an ADU possible.
For developers, they can improve project economics and increase housing capacity.
For investors, they create opportunities that may not have existed under older zoning regulations.
As with many of California’s recent housing reforms, the goal is not to eliminate reasonable development standards—it is to remove requirements that unnecessarily prevent new housing from being built.
