So, you’ve decided to explore adding an Accessory Dwelling Unit. That’s a smart move. It’s not just about adding square footage; it’s about adding potential. Whether you’re creating a private suite for returning college kids, a dedicated workspace away from the main house chaos, or a rental to offset those property taxes, it all starts with one critical step: a thoughtful, buildable design.
At A1 ADU Contractor, our Expert ADU Design Services in Sherman Oaks are the foundation of every successful project we build. We don’t just draw floor plans. We translate your goals into a design that respects your lifestyle, your lot, and the unique character of our neighborhood.
Let’s be real. The journey from “I want a garage conversion” to having a permitted set of plans can feel overwhelming. Setback requirements, utility hookups, Title 24 energy compliance—it’s a lot. Our design process cuts through that complexity. We start by listening to how you truly want to use the space. Is it a serene yoga studio for morning sessions before the Valley heat sets in? A fully-equipped in-law suite with easy access to the backyard? A sound-insulated music studio where the next big thing from Ventura Blvd can be composed? We’ve designed them all right here in Sherman Oaks.
We then pair your vision with a practical assessment of your property. That south-facing garage wall? It’s an opportunity for clerestory windows that fill a home office with natural light without sacrificing privacy. The typical single-car garage footprint? We’ve mastered plans that squeeze in a clever kitchenette and a full bath without feeling cramped. We think about how the afternoon breeze comes down the canyon and how to capture it, making your ADU comfortable year-round.
While converting an existing garage is a popular and efficient path, our design expertise covers the full spectrum. We help you evaluate the best approach for your specific property and goals.
| Design Path | Best For You If… | Key Consideration |
|---|---|---|
| Garage Conversion | You want a faster timeline and lower upfront cost. Your existing structure is in good shape. | Maximizing a limited footprint. Ensuring it feels like a welcoming home, not a converted garage. |
| New Detached ADU | You need more space or specific features. You want to keep your garage for storage or cars. | Navigating lot coverage and setback rules to place the new structure optimally. |
| ADU Above Garage | You have a taller garage or are building new. You want separation and potentially a view. | Structural engineering and designing a comfortable, accessible staircase. |
Our design service is where we nail down the specifics that turn a generic layout into your personal space. This is where we talk about:
Flow and function: Does the entrance for a rental unit feel private? Is there a logical place for a mini-split AC unit that’s both efficient and unobtrusive?
Material palettes: Durable luxury vinyl plank that handles spills from grandkids in a playroom, or polished concrete for that modern home gym look.
Built-in solutions: Custom shelving for a home library, integrated desk systems for a productive office, or specialized storage for a wine cellar or art studio.
We handle all the technical drawings, structural engineering stamps, and relentless back-and-forth with the City of Los Angeles Planning Department until you have that permit in hand. We’ve been through it countless times on streets from Valley Vista to Beverly Glen.
A1 ADU specializes in Accessory Dwelling Unit (ADU) design and building, turning unused garage spaces into functional, stylish living areas. Our process begins with understanding your needs, whether for rental income, guest space, or family use. We then design a custom layout that optimizes your space, prioritizes energy efficiency, and meets all local building regulations. With high-quality materials and expert craftsmanship, we handle everything from permitting to construction, delivering a finished ADU that enhances your home’s value and fits your unique lifestyle.
Once the ADU design is authorized, our team proceeds with acquiring the necessary permits to ensure full compliance with local regulations. After permits are approved, we begin site preparation, which may include structural assessments and utility connections. Our skilled builders then transform the garage, framing new walls, installing insulation, and adding windows and doors for optimal functionality and comfort. Plumbing, electrical, and HVAC systems are installed to meet modern standards. Finally, finishing touches like drywall, painting, flooring, and cabinetry bring the ADU to life, resulting in a complete, high-quality living space tailored to your needs.
Team worker made the process painless. The garage door conversion turned out seamless . Thanks a lot good service
I had a stressful lockout situation late at night, but AJ Locksmith is a game-changer. I called their emergency number, and the person I spoke with was calm and courteous. The locksmith, Robert, called when he was on his way and arrived in under 20 minutes. He was extremely professional and friendly, taking one look at the situation and unlocking my door without damaging anything. The best part was that the final cost was exactly as quoted over the phone. No surprise charges or hidden here somsd. I would highly recommend this company to anyone in need of a reliable emergency locksmith.
Professional team delivering solid ADU construction, clear communication, dependable timelines, and quality workmanship.
We hired this ADU builder for a garage conversion, and the entire process was seamless. Highly recommend them for any Accessory Dwelling Unit project!
Im glad that i used their service. They really retrofitted the place and it looks brand new. Very functional. And the price was spot on. Completely worth it. I am glad we contracted them
My garage was just collecting junk, now it’s a fully functional rental unit. The quality of the work is impressive and the attention to detail really paid off. I would definitely hire them again.
I can honestly say these guys know their craft. They transformed my cluttered garage into a beautiful ADU that looks like it was always part of the house. Everything was completed right on schedule.
The project added real value to our home. The garage door conversion gave us the base to create a small apartment for my parents. The team really cared about how it looked, not just how it worked. I’d happily use them again for another project. Thanks again!
I was skeptical at first because I’ve seen some bad garage conversions in the past. These guys proved me wrong with clean lines, solid work, and a perfect finish on the door conversion. The ADU doesn’t just function well, it looks amazing. Friends can’t believe how well it turned out.
The work was done with a lot of attention to detail. The old garage door opening was converted into something solid and stylish. I was surprised at how much this improved the overall look of the home. The new ADU is both practical and great looking.
In Sherman Oaks, you should plan for 4 to 6 months for a smooth design and permitting process. The timeline depends on the city’s current workload and the complexity of your project. We manage the schedule aggressively to avoid unnecessary delays.
We are a design-build contractor. Our designers think with a builder’s mindset from day one. We design to your budget, using materials and methods we know are readily available and cost-effective. There’s no disconnect between the beautiful plans and the reality of construction; we are responsible for both.
Absolutely, and we’ve done it many times. It requires smart, space-saving design choices—like a European-style washer/dryer combo, a shower niche instead of a bulky caddy, and compact appliances. The result is a completely functional studio apartment or in-law suite that feels spacious, not squeezed.
