Top 5 Most Common Questions About Building an ADU in Los Angeles (2025) #1 Can I build an ADU?

We talk to homeowners every day who are dreaming of building a rental unit, a private space for family, or just adding more room to their property—but they’re not sure if they can. So we’re kicking off a weekly series to answer the top 5 questions we hear most often.

This week we’re starting with the big one:

1. Can I Build an ADU on My Property?

Short answer: Most likely, yes!

If you own a house—or even a multi-unit building—there’s a really good chance you’re eligible to build an ADU. We’re talking about homes in all kinds of neighborhoods: from Santa Monica to Pasadena, Sherman Oaks to Inglewood.

Here’s what helps your property qualify:

🏡 Your property is zoned residential

Most single-family and multi-family zones now allow ADUs. Thanks to California’s updated housing laws, it’s easier than ever to build one—even if your local zoning used to say no.

📏 You’ve got at least 4 feet of space

To build a new structure (like a detached ADU), the city usually wants 4 feet of clearance from your side and back property lines.
But if you’re converting an existing garage? Those rules might not apply. Older garages that are right up to the fence can often be converted with no problem.

🧱 Lot size doesn’t matter anymore

There’s no minimum lot size. Whether your yard is big or small, if we can fit a code-compliant ADU that meets the setbacks and size limits, you’re in good shape.

📐 Size matters (but you’ve got options)

• Up to 850 sq ft for a 1-bedroom
• Up to 1,000 sq ft for a 2-bedroom
• Some cities allow more, depending on your main house size

If you want to attach the ADU to your house, you’re generally limited to 50% of your main home’s size, up to 1,200 sq ft total.

🌄 Some areas have extra layers

If you’re in a hillside zone, historic district, or coastal area, we might need to go through a couple of extra steps. It doesn’t mean it’s a no—it just means we’ll help navigate it.

🚗 What about parking?

In many cases, you don’t need to add any new parking.
If you’re near public transit (within ½ mile), or in certain zones, the parking requirement can be waived. And if you do need it, parking in your existing driveway often works.
