1. What is an Unpermitted ADU?

An unpermitted ADU is a secondary unit built on residential property without the necessary approvals or permits from local government agencies. In California, ADUs are additional living spaces that can be attached or detached from the main home. These can range from small backyard cottages to garage conversions, often created to provide extra income or housing for family members.

While unpermitted ADUs are common, they can create significant issues for homeowners—from potential fines to complications with property sales or insurance. Property owners sometimes build without permits to save time and money or because they are unaware of the legal requirements.

Homeowners exploring ADU options in California should be aware of new ADU laws in California 2025, which are set to simplify the process and create more opportunities for compliant construction.

2. The Legal Risks of an Unpermitted ADU in California

Owning or renting out an unpermitted ADU in California can lead to a range of legal problems. Some of the key risks include:

• Fines and Penalties: Building without a permit can result in costly fines. Depending on the local municipality, property owners may be required to pay backdated fees and incur additional penalties.
• Complications with Property Sales: When it comes time to sell, unpermitted ADUs may be flagged during inspections, making it difficult to find a buyer or secure financing.
• Insurance Issues: Insurance companies may refuse to cover damages caused by unpermitted units, leaving homeowners vulnerable to unexpected expenses.
• Legal Gray Area: Unpermitted ADUs can create confusion for landlords and tenants regarding safety standards and tenant rights.

3. California’s Path to Legalizing Unpermitted ADUs

For homeowners with unpermitted ADUs, California has taken steps to address the issue and streamline the legalization process. In 2017, the Unpermitted Dwelling Unit (UDU) Ordinance was introduced in Los Angeles, creating a voluntary program for owners to legalize unpermitted units, provided they meet specific life safety requirements. The goal is to add affordable housing to the market while ensuring safety and compliance.

In 2024, Assembly Bill 2533 (AB 2533) was passed to further expand the amnesty program for unpermitted ADUs and Junior ADUs (JADUs) built before January 1, 2020. Key benefits of AB 2533 include:

• Simplified Habitability Standards: Local agencies now use more flexible habitability standards instead of rigid building codes to evaluate the safety of ADUs.
• Waived Fees: Retroactive impact and connection fees are waived in most cases, making it easier for homeowners to afford the legalization process.
• Expanded Eligibility: The program now includes ADUs and JADUs built between January 1, 2018, and January 1, 2020, expanding the scope of units eligible for amnesty.

This provides homeowners with a more affordable and accessible path to legalize their unpermitted ADUs, reducing the burden of compliance.

4. The Process of Legalizing an Unpermitted ADU

Legalizing an unpermitted ADU requires navigating a clear process that includes inspections, safety upgrades, and local approval. Here are the basic steps involved:

• Assess the Existing ADU

Start by evaluating whether your ADU meets basic safety standards, including proper electrical, plumbing, and sewage systems. For guidance on meeting these standards, check out our detailed guide to ADU electrical requirements in California.

• Create Plans for Changes

If your ADU doesn't currently meet the necessary standards, you'll need to draw up plans to bring it up to code.

• Submit Plans for Approval

Once your plans are complete, submit them to your local planning department for review and approval.

• Schedule Inspections

After receiving approval, schedule safety inspections to ensure your ADU complies with building codes and safety requirements.

• Make Necessary Upgrades

If inspections reveal any deficiencies, complete the required upgrades—this may involve additional electrical work, plumbing fixes, or other adjustments. Familiarize yourself with Title 24 ADU requirements for energy efficiency and building standards in California.

• Obtain Legalization

Once all inspections are passed and required upgrades are completed, your ADU can be officially legalized.

Understanding additional regulations can further smooth the legalization process. For example, AB 1033 plays a role in changing the housing landscape in California, while SB 9 offers guidance for property owners. Also, if your property is part of a Homeowners Association in California, be sure to check any specific HOA rules that might affect your ADU plans.

7. Frequently Asked Questions (FAQs)

What happens if you have an unpermitted addition?

If you have an unpermitted addition to your property, you may face legal and financial risks. Local authorities may issue fines or penalties, and you could be required to remove the addition or bring it up to code. It may also be difficult to sell or refinance your property, as most buyers will want proof that all structures comply with building codes. Furthermore, if there are safety issues with the unpermitted addition, insurance companies may not cover damages.

Do you need a permit for an ADU in California?

Yes, in California, most ADUs require a permit, especially if the unit is detached or involves significant construction like plumbing or electrical work. The specific requirements depend on local zoning regulations and whether the ADU meets the state's standards for safety, utility connections, and habitability. However, some smaller ADUs or units that use pre-approved designs may be eligible for a streamlined approval process.

How do you permit an unpermitted addition?

To permit an unpermitted addition, the first step is to assess the existing structure to ensure it meets the necessary safety and building standards. You will need to submit plans for approval to your local planning department, which may include upgrading the addition to meet current building codes. After your plans are approved, you'll schedule inspections to ensure compliance. Once the addition passes inspection and any required upgrades are made, the unit can be legalized.

Can an unpermitted ADU be legalized in California?

Yes, California has several programs to legalize unpermitted ADUs, such as the AB 2533 Amnesty Program, which allows ADUs built before January 2020 to be legalized through a streamlined process. The legalization process typically involves submitting plans, passing safety inspections, and making any necessary upgrades. Legalizing an ADU can help property owners avoid fines, increase property value, and ensure that the unit is safe for use.

Can I sell my property with an unpermitted ADU?

While it’s possible to sell a property with an unpermitted ADU, it may complicate the sale. Many buyers may be hesitant to purchase a home with unpermitted additions due to potential legal issues, insurance concerns, or the need for costly repairs to bring the property up to code. If you plan to sell, it’s a good idea to either legalize the ADU or disclose its unpermitted status to avoid future legal disputes.

How long does it take to legalize an unpermitted ADU in California?

The time it takes to legalize an unpermitted ADU varies depending on the complexity of the unit, the local jurisdiction, and the availability of inspectors. On average, the process can take anywhere from a few months to a year. Steps include submitting plans, scheduling inspections, making required upgrades, and obtaining final approval from local authorities.

Can I build an ADU without a permit in California?

While it’s possible to build an ADU without a permit, doing so is not recommended. Building without the necessary permits can result in fines, complications when selling or refinancing, and issues with insurance. Instead, property owners should go through the proper permitting process to ensure that the ADU complies with safety and building codes.

What are the benefits of legalizing an unpermitted ADU?

Legalizing an unpermitted ADU ensures that the unit is safe and compliant with building codes. It can increase the property value, make the unit eligible for rental income, and protect you legally in case of disputes or safety issues. Additionally, legal ADUs contribute to California's affordable housing stock, helping address the housing crisis in the state.
