If you own an Accessory Dwelling Unit (ADU), Assembly Bill 1033 (AB1033) offers a unique opportunity to convert your ADU into a separate condominium that you can sell independently. Here’s why this could be a game-changer for your property and how you can take advantage of it.

What is AB1033?

AB1033, formally known as Assembly Bill 1033, is a California law that allows homeowners to legally convert their Accessory Dwelling Units (ADUs) into separate, independent condominium units. This legislation is part of the state's broader effort to increase housing availability and affordability by making it easier for homeowners to leverage their existing properties.

Purpose and Background:

AB1033 was introduced to address California’s ongoing housing crisis by providing homeowners with a way to monetize their ADUs. Traditionally, ADUs were secondary units that couldn’t be sold independently of the primary residence. This restriction limited the financial benefits homeowners could derive from their property. AB1033 changes that by allowing these units to be subdivided and sold as individual condos, thereby unlocking additional value.

Key Provisions:

Under AB1033, homeowners can:

  1. Subdivide Their Property: Legally separate their ADU from the primary residence, creating two distinct properties.
  2. File a Condo Plan: Submit a plan to local authorities that details the division of the property and outlines the boundaries and any shared spaces.
  3. Sell the ADU as a Condo: Once approved, the ADU becomes its own entity and can be sold independently of the primary home.

AB1033 Eligibility

To take advantage of AB1033 and convert an Accessory Dwelling Unit (ADU) into a separate condominium, certain eligibility criteria must be met. Understanding these requirements is essential before beginning the conversion process.

1. Compliance with Local Zoning Laws:

Your ADU must comply with all local zoning regulations. This includes restrictions on the size, height, and placement of the unit on your property. Each municipality may have specific rules governing where ADUs can be located and how they can be used. For example, some areas may have minimum lot sizes or specific setback requirements that must be adhered to for an ADU to qualify for conversion under AB1033.

To learn about AB1033 in depth refer to the California Legislative Information on AB1033.

2. Building Code Compliance:

The ADU must meet all local building codes. This includes structural standards, safety requirements, and accessibility features. Ensuring that your ADU is up to code is crucial, as any deficiencies could delay or prevent the conversion process. Building codes cover a wide range of aspects, from fire safety measures to electrical wiring and plumbing systems. It's essential to have your ADU inspected to confirm that it meets all necessary standards.

To see your county's specific compliance requirements refer to the California Department of Housing and Community Development website.

3. Property Ownership:

Only property owners who have a legal right to subdivide their land can pursue an AB1033 conversion. If your property is subject to a mortgage, you may need to obtain permission from your lender before proceeding with the subdivision and conversion. Additionally, if the property is owned jointly or as part of an estate, all owners must agree to the conversion.

4. Compliance with Homeowners Association (HOA) Rules:

If your property is part of a homeowners association (HOA), you must ensure that converting your ADU into a condo complies with the HOA’s rules and regulations. Some HOAs may have restrictions on property subdivisions or the use of ADUs, which could affect your ability to convert and sell the unit independently. It’s crucial to review your HOA’s governing documents and, if necessary, seek approval before moving forward.

5. Minimum Lot Size and Configuration:

In some cases, the property’s lot size and configuration may impact eligibility. For example, there may be minimum lot size requirements for the subdivision to occur, ensuring that each resulting parcel, including the one with the ADU, is viable and meets local standards for independent residential units.

Relationship with SB9: How Homeowners Can Benefit

AB1033 and SB9 work together to maximize your property’s potential. With SB9, you can subdivide your lot and build additional units, such as ADUs. Once these units are built, AB1033 allows you to convert them into separate condos that can be sold independently. This combination lets you increase housing density, create valuable property assets, and generate significant financial returns by selling off portions of your property while retaining ownership of the primary residence.

Unlock Your Property’s Potential: Financial Benefits of AB1033

AB1033 offers homeowners a unique opportunity to maximize the financial value of their property. Here’s how:

  1. Sell Your ADU Independently: By converting your ADU into a separate condo, you can sell it as an independent unit, potentially generating significant income without having to sell your entire property.
  2. Increase Property Value: The ability to sell your ADU as a standalone unit increases your overall property value. Buyers often find condos more accessible and affordable, which can drive up demand and selling price.
  3. Diversify Your Investments: Selling your ADU as a condo allows you to unlock equity in your property and use that capital for other investments or financial goals, such as paying off debt, reinvesting in your primary residence, or funding a new project.

Timeline for Conversion: How Long Will It Take?

Converting your ADU into a condo under AB1033 is a multi-step process that can take anywhere from a few months to over a year. Here’s what to expect:

  1. Initial Assessment (1-2 Months): Evaluate your ADU’s eligibility and compliance with local zoning and building codes. This phase includes consultations with professionals and potentially an initial inspection.
  2. Subdivision Process (2-6 Months): Legally separating your ADU from the main property involves surveys, drafting legal documents, and submitting applications to local authorities. The timeline here largely depends on the complexity of your property and local government processing times.
  3. Filing and Approval (3-9 Months): After subdivision, you’ll need to file a condo plan with local authorities. This plan will outline the details of the new condo, including property lines, shared spaces, and compliance with local regulations. The approval process can vary widely depending on the jurisdiction, the thoroughness of your documentation, and the local planning department's workload.
  4. Final Steps and Sale (1-3 Months): Once approved, the final steps include formalizing the condo’s legal status, completing any required construction or modifications, and listing the unit for sale. Depending on the market, selling the condo might be quick or take a bit longer.

Total Estimated Time: The entire process can range from 6 months to over a year. Working with experienced professionals and staying proactive can help ensure a smoother, faster conversion.
