Build an ADU Above Your Garage – (2 Story) ADUs in Los Angeles

Thinking about adding more space to your home? Building an ADU above your garage might be the perfect solution. In Los Angeles, more and more homeowners are choosing this smart upgrade. These units are also called garage conversions or 2 story ADUs. They are legal, practical, and boost your property value.
What is an ADU (Accessory Dwelling Unit)?
An ADU, or Accessory Dwelling Unit, is a small home built on the same lot as a main house. It can be a separate unit in your backyard, a converted garage, or even built on top of your garage. In Los Angeles, the rules for ADUs have changed to make it easier to build them.
Why Build an ADU Over Your Garage?
If you have a detached garage, it can be the perfect spot to build up. A 2 story ADU in Los Angeles gives you extra space without using up your yard. It keeps your parking space and adds a second floor for living.
Here are a few benefits of building an ADU over your garage:
- Extra income: Rent it out for monthly cash flow.
- More space: Use it as a guest room, office, or for family.
- Boost value: Homes with ADUs often sell for more.
- Privacy: A unit above the garage gives space between you and tenants.
Is It Legal to Build an ADU Over a Garage in Los Angeles?
Yes! The city has changed the rules to support housing growth. You can now build a garage ADU on many types of residential properties. But there are still rules for size, height, and setbacks. Working with a local expert like Snow Construction helps make sure your project is legal and safe.
What Makes a 2 Story ADU Special?
A 2-story ADU gives you more room without expanding your home’s footprint. Most often, the garage stays on the first level. The second level becomes a full living unit. This includes a kitchen, bathroom, and sleeping area.
You can design the unit to fit your needs. Whether it’s for a long-term renter or a family member, a 2 story ADU in Los Angeles is flexible and useful.
Design Tips for an ADU Above Garage
- Match your home: Keep the style similar to your main house.
- Add windows: Natural light makes small spaces feel big.
- Use smart storage: Built-ins can save space and look great.
- Plan for stairs: Outdoor stairs save space inside the unit.
How Long Does ADU Take to Build?
The timeline depends on design, permits, and materials. On average, it takes about 4 to 8 months from start to finish. A skilled contractor will guide you through each step, from planning to final touches.
Cost of Building an ADU on Top of a Garage
Costs vary but expect to invest more than a ground-level ADU. Why? Because of added framing, stairs, and structural work. But remember, a garage ADU also brings higher rental income and property value.
A custom ADU above the garage in Los Angeles can cost between $150,000 and $300,000. This depends on size, finishes, and design choices. Working with a licensed builder like Snow Construction ensures a smooth and affordable process.

Challenges & Solutions for Building an ADU Above Garage
Q1: What is the biggest challenge when building an ADU over a garage in Los Angeles?
A: One major challenge is making sure the existing garage can support the weight of a second floor. Many older garages were not built for this. You may need to reinforce the foundation or rebuild parts of the structure.
Solution:
A licensed local general contractor will inspect your garage and create a plan that meets building codes. At Snow Construction, we handle all structural upgrades to make sure your ADU above the garage is safe, legal, and built to last.
Q2: What if there’s not enough space for stairs inside the garage?
A: Stairs can take up a lot of room. In smaller garages, there may not be enough space to add stairs inside without losing parking or storage.
Solution:
One smart option is to build the stairs outside. Exterior stairs save space and can look great with the right design. Our team helps you choose the best layout for your ADU on top of garage—so you keep what you need and still gain a full living space.
