Can You Build an ADU Without Zoning Approval?
Building an accessory dwelling unit (ADU) is a great way to add value and space to your property, but zoning approval is often a necessary step in the process. While California has passed laws that make it easier to build ADUs, zoning rules still play a significant role in determining where and how an ADU can be built. At MF ADU, we guide homeowners through the zoning process to ensure their ADU project complies with local regulations and runs smoothly.
Why Zoning Approval is Necessary
Zoning laws are in place to ensure that new constructions meet local guidelines for land use, safety, and neighborhood aesthetics. Zoning approval helps ensure that your ADU won’t negatively impact the environment, traffic patterns, or local infrastructure. The approval process typically involves checking:
Lot size and setbacks: Ensuring the ADU fits within your property’s boundaries and meets required distances from property lines.
Density limits: Verifying that your property is zoned to allow multiple units.
Building codes and safety standards: Confirming that the ADU meets fire, electrical, and structural codes.
In general, zoning approval is required for both new constructions and conversions of existing spaces, ensuring that the ADU meets local regulations for safety and design.
Are There Exceptions to Zoning Approval for ADUs?
While zoning approval is often required, there are some exceptions and streamlined processes for ADUs in California. Recent laws, including SB 1121, have created more flexibility, particularly for properties already zoned for residential use.
When zoning approval might not be necessary:
By-right zoning: In some cases, if your property is in an area that allows residential units, and your ADU meets state and local guidelines, you may not need a discretionary zoning review.
Conversion of existing structures: If you’re converting an existing structure, such as a garage or storage shed, to an ADU, it may not require new zoning approval if it meets existing setbacks and other regulations.
However, you still need to comply with building codes, fire safety regulations, and permit requirements to proceed with construction.
What Happens if Zoning Approval Is Denied?
If your zoning request is denied, it doesn’t necessarily mean your ADU project is over. You can:
Request a variance: A variance allows you to deviate from certain zoning rules if your ADU doesn’t fully comply with regulations but still meets overall goals like safety and accessibility.
Adjust your plans: You may be able to revise your design to meet zoning codes, such as reducing the size of your ADU or altering its placement on the property.
At MF ADU, we help homeowners navigate zoning regulations and find solutions if zoning approval is initially denied.
Did you know?
Did you know? Some cities in California are required to issue a permit for an ADU within 60 days if the application meets all state and local requirements, simplifying the approval process.
