ADU design, plans, permits, and build support
At Uni Construction + ADU Design, we do more than sketch ideas. We help turn them into workable ADU projects. Our team provides adu plans, layout guidance, design support, permit coordination, and build-focused planning so your project can move forward with more clarity and fewer surprises.
If you need a practical adu builder and adu contractor approach in San Gabriel, we focus on the parts that matter most: usable space, smart layout decisions, realistic build direction, and a process that stays organized from the start.
Built for San Gabriel homeowners and property owners
San Gabriel properties often need thoughtful planning, especially when space, access, and layout all matter. That is why our adu services are built around real property needs, not generic templates.
Whether you want extra room for family, a private guest space, rental potential, or a better use of your backyard or garage, we help you move toward a custom solution that fits your property and long-term goals.
Why ADUs Make Sense for San Gabriel Properties
San Gabriel homeowners often want more space without giving up the home and neighborhood they already love. A well-designed ADU can help you add flexibility to your property while keeping the footprint practical and the layout intentional.
With Southern California’s mild weather and year-round use of outdoor space, ADUs can work especially well as backyard living spaces, private guest units, family accommodations, or flexible rental-ready additions. In a city where property use matters, a thoughtfully planned ADU can make your lot work harder for you.
Extra living space without leaving your property
An ADU gives you a separate, functional space right where you already live. That can mean more privacy, better layout flow, and more room for everyday life without the stress of relocating.
A practical option for family, guests, or rental use
Many property owners explore ADUs for aging parents, adult children, long-term guests, home office flexibility, or added rental use. The right design makes that space feel comfortable, efficient, and connected to the property in a smart way.
ADU Options We Build in San Gabriel
Detached ADU
A Detached ADU is a strong choice when you want privacy and separation from the main home. Detached units work well for backyard living spaces, guest suites, rental use, or multigenerational living with more independence.
Attached ADU
An Attached ADU connects to the main structure while creating its own functional living area. This option can make sense when you want to expand usable square footage while keeping the design closely integrated with the existing home.
Junior ADU
A Junior ADU can be a smart fit for smaller conversions and efficient layouts. It is often a good option when you want a compact additional living space while making use of an existing part of the home.
Garage Conversion
A Garage Conversion is one of the most practical ways to create an ADU from space you already have. With the right planning, an underused garage can become a comfortable, functional living area with better long-term value and purpose.
Modular ADU
A modular adu can be worth considering when project goals, design preferences, and site conditions align. We help you evaluate whether a modular approach makes sense for your property and how it fits into the broader design and permit process.
Custom ADU plans and floor plans
Some projects need more than a standard layout. We help create custom adu concepts with practical adu floor plans, smarter room flow, and better use of available space. Whether you need compact efficiency or a more open plan, your ADU should fit the way the space will actually be lived in.
Why Choose Uni Construction + ADU Design
Choosing the right ADU team is not just about getting drawings or starting construction. It is about working with people who can guide the full process in a clear, realistic, and build-focused way.
Serving San Gabriel since 2014
We have been serving property owners since 2014 with a practical approach to design, planning, and construction support. Experience matters in ADU work because every decision affects layout, approvals, usability, and build readiness.
Custom ADU solutions for residential and commercial properties
We provide custom adu solutions for both residential and commercial property needs. That means we look at the property, the intended use, the available space, and the goals behind the project before shaping the design path.
A direct design-and-build approach from start to finish
Our process stays direct. We help move the project from consultation to planning, permits, and build support without making the process feel scattered or confusing. That kind of structure matters when you want an ADU project to move forward with confidence.
Our ADU Process: Plan, Design, Permit, Build
A good ADU process should feel clear, not overwhelming. We keep the path straightforward so you always know what comes next.
Project consultation
We start by learning about your property, your goals, and the type of ADU you want to build. This first step helps define the right direction before time and money go into the wrong concept.
ADU design and planning
Next, we shape the layout, space plan, and overall design approach. This is where adu plans, use-case needs, and practical design decisions come together to support a better project outcome.
Permit coordination
Permits are a major part of any ADU project. We help guide the permit side of the process so the project can move toward approval with better organization and fewer avoidable delays.
Construction and completion
Once the design and permit path are in place, the project moves into the build phase. Our design-and-build mindset helps keep the project grounded in what can actually be executed well on site.
ADU Design Ideas for Backyard and Garage Conversion Projects
A strong ADU should do more than fit on the property. It should feel comfortable, efficient, and visually aligned with how you want the space to be used.
Detached backyard ADU concepts
Detached backyard ADUs can work beautifully for private living space, guest accommodations, or flexible rental use. Clean layouts, natural light, strong indoor-outdoor flow, and smart separation from the main home often make these designs feel more spacious than their footprint suggests.
Attached and garage conversion layouts
Attached units and garage conversions need thoughtful planning to make every square foot count. The best layouts create privacy, improve flow, and make the new space feel intentional rather than like an afterthought.
Custom finishes and practical space planning
From a small adu to a more open modern adu, the details matter. Good adu designs balance storage, comfort, natural light, circulation, and finish choices so the final result feels complete, usable, and attractive.
What Affects ADU Project Cost in San Gabriel?
Every ADU project is different, so cost depends on the scope and conditions of the property rather than one flat number.
Size, layout, and ADU type
Project cost can shift based on whether you are building a Detached ADU, Attached ADU, Junior ADU, or Garage Conversion. The size of the unit and the complexity of the layout both play a major role.
Site conditions and permit requirements
Existing site conditions, property access, utility considerations, and permit requirements all affect how simple or complex a project may become. These details often shape both timeline and budget.
Custom design and build scope
A more customized layout, upgraded finishes, or a broader build scope can change the overall investment. The best way to understand cost is to review your property goals and request a quote based on the actual project, not a guess.
