What Can I Actually Build in My Backyard?
Can I Build an ADU in My Backyard in California?
School is back in session, fall is around the corner, and Q4 is always a busy time for homeowners thinking about adding space. One of the top questions we hear before anyone ever jumps on a call with us is:
That’s exactly why we built the free Check My Backyard tool. Instead of guessing, you can type in your address, play around with our ADU floorplans, and even save a design. It’s the easiest way to get clarity before you start planning.
Quick Checklist: Can You Build an ADU in Your Backyard?
Here are a few things to check off before you get too far down the path:
- Overhead Power Lines – Do you have them running across your yard? These can make placement tricky.
- Slope – A heavily sloped yard can still work, but expect grading and foundation costs to be higher.
- Distance From the Street – Every ADU needs to connect to water, sewer, and electricity. The farther back you place it, the more trenching you’ll need. (We cover the first 50 feet; beyond that there’s a small extra charge. Most homeowners go over, so don’t stress—this is standard for prefab and traditional builds alike.)
- Setbacks – You’ll need clearance between your ADU and your lot lines. In California, a good rule of thumb is 4 feet from the sides, 6 feet from the back, and about 6 feet from your main home.
These aren’t LiveLarge-specific rules—they’re just part of building an ADU, whether prefab or traditional.
Why Use the Tool First?
Because it saves you time and frustration. The Check My Backyard tool isn’t perfect—setback presets vary city by city—but it’ll get you 80% of the way there.
And that’s a huge step before you ever spend money on drawings, permits, or site visits.
