What's included

Everything you should know about ADUs

An ADU is a fully self-contained living unit on your property: kitchen, bathroom, separate entrance. The numbers in LA right now are remarkable, let's walk through what's possible.

Detached vs. Attached

Detached: standalone in the backyard. Attached: shares a wall with the main home. Each has different cost and code implications.

Garage Conversions

The fastest, lowest-cost path to an ADU, converting an existing 400 sq ft garage into a code-compliant studio or 1-bedroom.

Permits and Codes

California's SB-9, SB-10, and ADU laws have streamlined approvals dramatically. Most ADUs are now ministerial, no design review.

Rental Income

A typical LA ADU rents for $2,200-$3,800/month. Many homeowners cover the construction loan with rent in 8-12 years.

Multigenerational Use

Aging parents, adult children, college-age kids. An ADU keeps family close while preserving privacy and independence.

Cost and Timeline

Garage conversions: $100K-$180K, 4-6 months. Detached new-build ADUs: $200K-$400K+, 8-12 months. Permits typically 6-12 weeks.

How it works

Our ADU process

01

Lot and feasibility review

We pull setback rules, lot coverage limits, and any HOA covenants. Most lots qualify, we tell you within a day.

02

Design and plans

Floor plans, exterior renderings, MEP drawings. We design for code, livability, and rental value all at once.

03

Permit submittal

Most LA ADUs are ministerial review, straightforward, predictable, fast. We handle every step with the city.

04

Build phase

Foundation, framing, MEP rough-in, drywall, finishes, kitchen, bath. We build ADUs to the same standard as a primary residence.

05

C of O and rent-ready

Final inspection, certificate of occupancy, and (if you want) help connecting with property managers and rental platforms.

A to Z did a fantastic job with our kitchen remodel. We have a 100-year-old Spanish style home and wanted to keep a lot of the original elements — Zack and Rami really listened and helped us figure out how to get it just right. Couldn't be happier with our new kitchen.
Tess L.Kitchen Remodel · Los Angeles · Yelp
★★★★★
A to Z built a beautiful ADU in our backyard. The project was on budget and the results were better than we had hoped. Rami and Zack were a consistent and communicative presence at the job site. We looked at 10 firms in total and are so pleased we chose A to Z.
Robert R.ADU Build · Sherman Oaks · Yelp
★★★★★
A to Z, lead by Rami and Zach, are the absolute best. My bathroom remodel was complicated and they worked meticulously to make our vision a reality. They communicated well, showed up on time, left the work site clean every day. No problem was too hard and the work they did was beautiful.
Abby H.Bathroom Remodel · Agoura Hills · Yelp
★★★★★
We interviewed several contractors and hired A to Z. Couldn't be more pleased with the results! Two bathrooms, new lighting, a new roof, HVAC, windows, flooring, and paint. From the start they gave us clear and honest advice, and the work speaks for itself. Highly recommended!!

★★★★★
I have used A to Z's services twice. Most recently they rebuilt my home after a house fire. The estimates were reasonable and thorough. Many of the skilled workers on the A to Z team have been with the company for years and it's clear they take pride in their work. Their estimates are honest.

Zack, Rami and their crew did a fantastic job! Full renovation for two 1950's bathrooms that came out beautifully. Reasonable price especially in comparison to the other company I contacted. Trustworthy company with frequent updates from Zack who also provided invaluable input and suggestions. Highly recommend!
