Can I Build an ADU in My Backyard in California?
What Can I Actually Build in My Backyard?
If you’re like most California homeowners, you’ve probably stood in your backyard and wondered:
- What’s the biggest unit I can fit here?
- What are the setback rules I need to follow?
- Will these new prefab units I’ve been seeing actually fit on my lot?
You’re not alone. These are some of the most common questions we hear every day from people who are curious about ADUs and backyard units.
The challenge is, most homeowners get stuck in the “guessing stage.” You look at your yard, maybe take a few measurements, but then you hit a wall: city regulations, construction estimates, and confusing contractor advice. Suddenly the project feels overwhelming, and you stop before you start.
At LiveLarge, we believe you shouldn’t have to jump through hoops just to find out what’s possible.
Why Homeowners Get Stuck
Building an ADU or backyard unit isn’t just about size—it’s about rules, logistics, and fit.
- Setbacks: Most cities require that new units be a certain distance from property lines, fences, or existing structures.
- Utility hookups: ADUs need sewer, water, and electrical access, which can affect placement.
- Unit size: California allows backyard units from as small as 120 sq ft (like our POD) all the way up to 1,200 sq ft. But not every lot can handle the maximum size.
Without clear guidance, it’s easy to feel like you’re spinning your wheels.
A Free Tool to End the Guesswork
That’s exactly why we built Check My Backyard.
Instead of hiring a contractor or waiting weeks for an estimate, you can:
- Type in your address.
- See what fits—whether it’s a compact POD, a rental-ready 750 sq ft ADU, or one of our larger two-bedroom units.
- Visualize placement on your lot, so you know exactly how setbacks and space will affect the design.
You can even save your design and come back to it later. And when you’re ready, our team will reach out to walk you through next steps.
What Happens After You Check?
Once you’ve used the tool, you’ll get a design emailed back to you. If you’re serious and want to move fast, just reply to that email—we’ll hop on a call, review your design together, and see what’s possible on your property.
If you’re still early in the process, that’s fine too. The tool gives you a baseline so you can plan at your own pace.
