If you're considering building a 2-story ADU on your property in Los Angeles, you've come to the right place. This comprehensive guide will walk you through everything you need to know about the process - from understanding ADU regulations to planning, construction, and maximizing the value of your investment. Whether you're looking to create additional living space for family members or generate rental income, this guide will provide you with the essential information and insights to successfully navigate the journey of building a 2-story ADU in Los Angeles. Let's get started!
With the growing need for affordable housing and the desire for flexible living arrangements, Accessory Dwelling Units (ADUs) have become a popular solution. ADUs, also known as granny flats, in-law suites, or backyard cottages, are secondary dwelling units that are built on the same property as a primary residence. These units provide homeowners with the opportunity to maximize their property's potential, whether it's for accommodating extended family members, generating rental income, or simply adding more space for personal use.
An ADU is a self-contained living space that is secondary to the main dwelling on a property. It can be either attached or detached from the primary residence and typically includes a separate entrance, kitchen, bathroom, and living area. ADUs can vary in size and layout, ranging from a converted garage or basement to a purpose-built structure in the backyard.
There are numerous benefits to building a 2-story ADU in Los Angeles:
1. Increased Property Value: Adding an ADU to your property can significantly increase its value. It provides potential buyers or renters with additional living space, making your property more attractive in the competitive Los Angeles real estate market.
2. Rental Income: Renting out your ADU can generate a stable source of income. With high demand for housing in Los Angeles, renting out your ADU can be a lucrative investment opportunity.
3. Multi-Generational Living: ADUs offer a convenient housing solution for multi-generational families. By providing separate living spaces on the same property, families can enjoy the benefits of close proximity while maintaining privacy and independence.
4. Flexibility: ADUs can serve various purposes, including a home office, guesthouse, or a space for aging parents or adult children. They provide homeowners with the flexibility to adapt their living arrangements to changing needs.
There are different types of ADUs that you can consider when planning to build a 2-story unit in Los Angeles:
1. Attached ADU: This type of ADU is connected to the primary residence, sharing one or more walls. It can be an extension of the existing structure or a conversion of an existing space, such as a garage or a basement.
2. Detached ADU: A detached ADU is a separate structure from the primary residence, located in the backyard or on a different part of the property. It offers more privacy and can be designed to match the architectural style of the main house.
3. Junior ADU (JADU): In addition to a standard ADU, Los Angeles allows the construction of a Junior ADU within an existing single-family home. A JADU is a smaller unit with a maximum size of 500 square feet and has its own entrance, bathroom, and kitchenette.
Before embarking on your ADU construction journey, it's crucial to familiarize yourself with the regulations and restrictions imposed by the city of Los Angeles. These regulations cover aspects such as zoning requirements, building codes, and the permitting process. Understanding these guidelines will ensure that your 2-story ADU complies with the city's regulations and can be built legally and safely.
In the next section, we will delve into the specific ADU regulations and requirements set forth by the city of Los Angeles, providing you with a comprehensive understanding of the necessary steps to build your 2-story ADU.

Zoning regulations dictate where ADUs can be built within the city and specify requirements such as lot size, setback requirements, and height limitations. It is important to check the zoning designation of your property to determine if it is eligible for constructing an ADU. In Los Angeles, ADUs are generally allowed in single-family residential zones, but specific requirements may vary based on the neighborhood.
Some key zoning regulations to consider include:
1. Lot Size: The minimum lot size required to build an ADU varies depending on the zoning designation. For example, in R1 zones, the minimum lot size is typically 5,000 square feet.
2. Setbacks: Setbacks refer to the distance between the ADU and the property lines or other structures. Los Angeles has specific setback requirements for ADUs, which may vary based on the zoning designation and the type of ADU (attached or detached).
3. Height Restrictions: The height of an ADU is regulated by the city to ensure it is compatible with the surrounding neighborhood. Maximum height limitations may vary based on the zoning designation and the type of ADU.
It is important to consult the Los Angeles Department of City Planning or a professional architect to determine the specific zoning regulations applicable to your property.
Building codes and standards ensure that your 2-story ADU meets safety and structural requirements. In Los Angeles, ADUs must comply with the California Building Code (CBC) and other relevant codes, such as the Los Angeles Residential Code (LARC) and the Los Angeles Green Building Code (LAGBC).

Designing your 2-story ADU involves making important decisions regarding the layout, style, and functionality of the space. Consider the following factors during the design process:
1. Space Allocation: Determine how you want to allocate the space within your ADU. Consider the number of bedrooms, bathrooms, living areas, and kitchen layout based on your needs and the size of your property.
2. Accessibility: If you plan to accommodate individuals with mobility challenges or aging family members, consider incorporating accessible features such as widened doorways, grab bars, and wheelchair-friendly design elements.
3. Natural Light and Ventilation: Maximize natural light and airflow by strategically placing windows, skylights, and ventilation systems. This not only enhances the overall comfort of the ADU but can also help reduce energy consumption.
4. Privacy and Noise Control: Consider the privacy of both the main house and the ADU. Design features such as separate entrances, soundproofing materials, and landscaping can help ensure privacy for both dwellings.
5. Aesthetics and Compatibility: Design your 2-story ADU to complement the architectural style of your main house and the surrounding neighborhood. This will help maintain harmony and consistency within the property.
Working with an architect or a professional designer specializing in ADUs can assist you in creating a functional and aesthetically pleasing design that meets your unique requirements.
Selecting the right contractor is crucial for the successful construction of your 2-story ADU. Consider the following factors when choosing a contractor:
1. Experience: Look for contractors who have experience in building ADUs in Los Angeles. They should be familiar with the local regulations, building codes, and permitting process.
2. Portfolio and References: Review the contractor's portfolio of past projects to ensure they have a track record of delivering high-quality work. Additionally, ask for references and contact previous clients to inquire about their experience working with the contractor.
3. Licensing and Insurance: Verify that the contractor holds the necessary licenses and insurance coverage. This ensures that they are qualified to undertake the construction and protects you from liability in case of accidents or damages.
4. Communication and Collaboration: Choose a contractor who communicates effectively and is willing to collaborate with you throughout the planning and construction process. Open lines of communication are essential for a smooth and successful project.
Obtaining multiple bids and conducting thorough interviews with potential contractors will help you make an informed decision and find the right fit for your project.
Estimating the cost of building a 2-story ADU is crucial for budgeting and financial planning. Several factors contribute to the overall cost, including:
1. Size and Complexity of the ADU: The size and complexity of the ADU, including the number of rooms, bathrooms, and special features, will impact the cost. A larger and more intricate ADU will generally require a higher budget.
