Custom ADU Builder and Contractor Services in Pomona
A successful ADU project needs more than a sketch and a contractor. It needs a coordinated plan. Uni Construction + ADU Design helps with ADU plans, design decisions, permit support, and a build-ready path so your project moves forward with fewer surprises.
Whether you are planning a detached backyard unit, an attached addition, a garage conversion, or a junior ADU, we focus on practical layouts, code-aware planning, and a smoother design-to-build experience.
ADU design, plans, permits, and build support
Our ADU work is designed to reduce confusion and keep the project moving in the right direction. Instead of leaving homeowners to figure out separate design, planning, and build stages on their own, we provide support across the process.
Included services: ADU plans; ADU floor plans; custom ADU design; permit support; ADU design and build; construction for approved ADU projects.
Built for Pomona homeowners and property owners
Pomona property owners often want more usable space without giving up the home and neighborhood they already value. That is where the right ADU builder makes a difference. We help shape projects around how you plan to use the space, whether that means family living, guest use, rental flexibility, or a more functional property setup.
If you are comparing options, our broader ADU builder services can give you a better feel for how we approach planning, design, and construction across Southern California.
Why ADUs Make Sense for Pomona Properties
Pomona’s Mediterranean climate brings hot, dry summers, mild winters, and plenty of sunshine, which makes backyard living space, garage conversions, and well-planned detached units especially practical for many properties.
Extra living space without leaving your property
An ADU can give you the extra room you need without the cost and disruption of moving. For many Pomona homeowners, it is a smart way to create privacy, flexibility, and better use of the lot you already have.
A practical option for family, guests, or rental use
A well-designed ADU can work as a space for extended family, adult children, guests, or future rental use. The goal is not just to add square footage. It is to create a small home that feels intentional, comfortable, and worth the investment.
ADU Options We Build in Pomona
Detached ADU
A detached ADU is a strong fit for property owners who want privacy, a separate entrance, and a true stand-alone living area. These projects work especially well for backyard layouts that can support an independent structure.
Attached ADU
An attached ADU can be a smart option when you want to expand from the existing home while keeping a more connected footprint. This works well for properties where layout efficiency matters more than full separation.
Junior ADU
A Junior ADU uses part of the existing home and is usually the most compact path. The City of Pomona defines a JADU as a smaller unit within the existing footprint of a single-family residence, with an efficiency kitchen and the option to share a bathroom with the main dwelling.
Garage Conversion
A garage conversion can be one of the most practical ways to create a livable ADU from space you already have. Done right, it can shorten the path from concept to useful square footage while still feeling finished, private, and comfortable.
Modular ADU
A modular ADU can make sense when speed, efficiency, and streamlined construction matter. The right solution depends on site conditions, access, design goals, and how the project needs to fit local requirements.
Custom ADU plans and floor plans
No two Pomona lots are exactly alike. That is why custom ADU plans matter. We help shape floor plans around your lot, setbacks, access, intended use, and the type of space you want to create, whether that is a small ADU, a modern ADU, or a more traditional layout.
Why Choose Uni Construction + ADU Design
Choosing the right ADU company means choosing a team that understands how to move a project from idea to finished build without making the process harder than it needs to be.
Serving Pomona since 2014
Since 2014, Uni Construction + ADU Design has worked with property owners who need a more practical, better-managed path from concept to construction.
Custom ADU solutions for residential and commercial properties
Your property, your layout, and your goals should shape the project. We do not treat every lot the same. We focus on custom ADU solutions that match the site, the use case, and the budget realities behind the build.
A direct design-and-build approach from start to finish
ADU projects can stall when planning, permits, and construction are treated like separate worlds. Our approach is more direct. We connect the design intent to the real build path so decisions stay grounded in scope, function, and constructability.
Our ADU Process: Plan, Design, Permit, Build
A clear process makes the entire project easier to understand. It also helps reduce delays, confusion, and misalignment along the way.
Project consultation
We start by understanding the property, the type of ADU you want, and the goals behind it. This is where we look at the lot, discuss ideas, and help narrow the right project direction.
ADU design and planning
Next comes ADU design, layout planning, and floor plan development. We shape the unit around how it will actually be used, not just how it looks on paper.
Permit coordination
Pomona’s ADU page includes an application, a plan check guide, a certificate of occupancy resource, ADU standards, and estimated fees for reference, so permit planning is a real part of moving a project forward the right way.
Construction and completion
Once plans and approvals are aligned, the build phase moves into execution. The goal is a finished ADU that feels clean, usable, and worth the investment, not a rushed add-on that creates problems later.
ADU Design Ideas for Backyard and Garage Conversion Projects
Detached backyard ADU concepts
Detached backyard ADUs work best when the design respects both privacy and flow. Good concepts usually balance windows, setbacks, outdoor circulation, and a footprint that feels natural on the lot.
Attached and garage conversion layouts
Attached ADUs and garage conversion projects usually need smarter space planning because every wall and every opening matters more. A strong layout can make a compact unit feel open, useful, and comfortable.
Custom finishes and practical space planning
Good ADU design is not just about style. It is about how the kitchen works, where storage goes, how light moves through the unit, and whether the floor plan supports everyday living. That is what turns a small ADU into a space people genuinely want to use.
What Affects ADU Project Cost in Pomona?
Every ADU project is different, which means pricing depends on more than one factor. Rather than using generic numbers that do not reflect the property or the scope, it is better to look at the project based on the real conditions involved.
Size, layout, and ADU type
Project cost usually starts with the basics: the type of ADU, the square footage, and how simple or complex the layout needs to be. A detached ADU, attached ADU, junior ADU, and garage conversion all carry different planning and construction demands.
Site conditions and permit requirements
Lot access, grading, utility considerations, and city review all affect the final price. Pomona also publishes estimated ADU fees for reference, and notes that actual cost can vary based on valuation, fixture count, and square footage.
Custom design and build scope
The more tailored the design, finishes, structural work, and site work, the more the cost can move. That is why the best next step is a project-specific review, not a guess.
Frequently Asked Questions About ADU Services in Pomona
We help with detached ADUs, attached ADUs, junior ADUs, garage conversions, modular ADUs, and custom ADU layouts shaped around the property and intended use.
