How I Evaluate a Los Angeles Property for ADU Potential

When I’m looking at a property in North Hollywood, Burbank, Studio City or Sherman Oaks, I don’t start with the question, “Can I fit an ADU back here?”

I start with the property that’s already there.

A lot of the housing stock in this part of Los Angeles gives you clues pretty quickly: an older single-family house sitting toward the front of a deep lot, a long driveway running to a detached garage, or an underused rear yard that may have more potential than the listing gives it credit for.

But a big backyard by itself doesn’t tell me much.

I want to know how the entire site works.

The Same 7,500-Square-Foot Lot Can Be Two Very Different Properties

This comes up constantly in the Valley.

Take two 7,500-square-foot lots in North Hollywood. One has a modest house pushed toward the front, a driveway along the side and a detached garage at the rear. The other has a larger house sitting near the middle of the lot with additions extending toward the backyard.

Same lot area.

Very different opportunity.

The first property may already have the basic geometry for a separate living space in the rear. The second may technically have enough land, but actually creating another unit could interfere with the existing house, outdoor space or construction access.

That’s why I care more about how the lot is organized than the lot-size number by itself.

Detached Garages Get My Attention

Older detached garages are common enough around North Hollywood and Burbank that they’re one of the first things I notice when I’m evaluating a property.

I’m not automatically assuming, “Great, convert the garage.”

I’m looking at where it sits.

Is it at the back of the property? Is there a driveway or alley serving it? How close is it to the house? What would happen to parking? Could a future resident reach the unit without walking through the main house’s private outdoor space?

Sometimes the garage itself is the opportunity.

Sometimes its location is more valuable than the building.

Then I Start Looking at It Like a Site

This is where my engineering background changes what I notice.

On many flatter properties in North Hollywood and Burbank, the site itself may be relatively straightforward. But move into parts of Studio City or Sherman Oaks and grade can become a much bigger part of the conversation.

Now I’m looking at retaining walls, drainage, access, elevation changes and what it might take to get utilities to another structure.

Even on a flat lot, I want to know where water goes, where the sewer connection is likely located and how much of the property is already covered by buildings and paving.

Those things aren't as exciting as the rendering of the finished ADU.

They can be a lot more important to the budget.

City Lines Matter Too

“Los Angeles” can be misleading when evaluating development potential.

A house in North Hollywood and a house a few blocks away in Burbank can look almost identical and sit on similarly sized lots, while being governed by different cities and different local processes.

That matters.

California establishes the broader ADU framework, but I still want to know which jurisdiction I’m dealing with before I start making assumptions about a particular property.

This is one reason I don’t like evaluating ADU potential from the MLS description alone.

Then I Run the Investment Question

Suppose I think a property could realistically support a unit that rents for around $2,500 per month.

That’s potentially $30,000 a year in gross rental income.

Great.

Now: what does it cost me to create it?

A relatively straightforward project behind an existing North Hollywood house and a project requiring significant site work on a more constrained property can produce similar rents while requiring very different investments.

That difference matters to me more than whether both properties can technically advertise “ADU potential.”

What Else Can This Property Do?

That’s ultimately the question I’m trying to answer.

When I look at a Los Angeles property, I’m looking beyond the house that happens to be sitting there today.

Could the detached garage become something else?

Could another unit work without ruining the backyard?

Does the lot configuration create an opportunity that other buyers might overlook?

Or does the property only look promising until you start thinking about access, utilities, drainage and construction?

Sometimes the answer is an ADU.

Sometimes it’s another form of additional housing or a better use of an existing structure.

And sometimes the right answer is that the “ADU potential” isn't worth paying extra for at all.

That’s the distinction I’m interested in.
