ADU, Garage Conversion & Room Addition

Build additional living space with ADU construction and garage conversions designed for rental income, family housing, or flexible living space.

An ADU, run as one job

For Los Angeles homeowners adding a second unit for rent, for family or for long-term value. We draw it, permit it and build it, so there is no gap between an architect, a permit expediter and a builder for your project to fall into.

How we price your project

No two ADU projects cost the same, and any contractor who quotes a number before seeing the property is guessing. These are the six things your project manager measures on the walkthrough.

Size and type

Square footage, and whether it is detached, attached, a garage conversion or a JADU.

Running water, sewer, gas and a new panel to a second unit is often the largest line on the estimate.

So how do you get an actual number?

You book a walkthrough. Nobody quotes a ADU project over the phone, and anyone who does is going to revise it later. Here is exactly what happens instead, and none of it commits you to anything.

01

We walk the property. Free, in person, no obligation.

02

You get a written estimate, itemized line by line, with nothing hidden in it. Yours to keep.

03

Any change is agreed in writing before the work happens, never after.

The three things people ask before they sign

These come up on almost every call. Straight answers to all three.

Will the price change once you start?

You get a written estimate, itemized line by line. Anything that comes up after that is priced and agreed in writing before the work happens, never after.

How long is this really going to take?

Nobody can give you a firm completion date before permits are issued, and anyone who does is guessing. You get a phase by phase schedule instead, and a call the week anything moves rather than a surprise at the end.

Will the work last?

Every stage is permitted and inspected under our license, CSLB #1076567, and the same team is on it from the first day through final walkthrough.

Every one of these is a ADU project, not a small job. Names, neighbourhoods and dates as they were left.

Book your free in-home estimate

Six questions, about thirty seconds. They go straight to a project manager who works on this kind of job.

Free, in person, and there is no obligation at the end of it.

You get a written, itemized estimate that is yours to keep.

A project manager comes out, not a salesperson.

Or just call and skip the form.

Budget and start date help us send the right project manager. Neither is a commitment.

Questions we get asked a lot

Or just call. We answer all of these on the phone in about five minutes.

How much does an ADU cost to build in Los Angeles?

It depends on the six things above. Your project manager gives you a written, itemized number after walking the property, not before.

How long does an ADU take to build in Los Angeles?

It depends on scope and on the permit path at your address, and the permitting part sits in a queue nobody controls. We split it into three durations, design, permits and construction, so you can see which part is moving and which part is waiting.

Do I need permits for an ADU or garage conversion?

Yes, always. We handle LADBS, prepare the drawings and coordinate plan check from start to approval.

Can I rent the ADU out?

That is what most of our clients build them for. We build to code so the unit can be permitted, inspected and legally occupied.

Can any garage be converted?

Not every one. Ceiling height, foundation, setbacks and drainage all matter. We tell you at the walkthrough whether yours works.
