ADU

ADU

Adding an ADU is one of the smartest ways to add living space and long-term value to your property, but the process can feel like a maze of design choices, permits, and contractor phone tag. That’s exactly where the Relay Home Co. family steps in. We connect you with a vetted local builder like Benson ADU Builders, then wrap the entire project in one clear promise: a written price before work starts, real-time tracking from first design to final inspection, and a 365-Day Done Right Promise that stands behind every nail and panel. You’ll know what you’re getting, what it costs, and when it’s done.

What’s Included

Every ADU project through the Relay Home Co. family follows the same playbook: a written plan, a written price, and photo updates at each milestone so you never wonder what’s happening on your property.

Detached ADU Construction

A standalone unit in your backyard gives you a fully separate address: kitchen, bath, bedroom, and its own entrance. Benson ADU Builders works with leading prefab brands including Abodu, Cover, and Dvele, which means much of the structure is built in a controlled factory and assembled on-site. That cuts months off traditional construction timelines and dramatically reduces weather delays and surprise material shortages.

Garage Conversion ADUs

If you have an underused garage, converting it into a living unit often costs less than building new because the foundation, framing, and roof are already there. Benson’s team handles the full conversion: insulation, plumbing, electrical, drywall, and finishing. You get a rentable unit or an in-law suite without sacrificing any yard space.

Home Addition ADUs (Attached)

Sometimes the best ADU is attached to the main house with a shared wall but a private entrance. This approach works well on smaller lots or when you want an aging parent close by but not entirely under the same roof. Benson designs and builds these as true additions, matching rooflines and finishes so the new space looks original to the home.

Prefab ADU Installation

Some homeowners want a faster path, and that’s where prefab shines. Benson is authorized to build with Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed alongside Abodu, Cover, and Dvele. You get factory precision, independent brand warranties you can research yourself, and a team that handles site prep, permitting, and finish work. James Hardie cladding is available across projects for durability and fire resistance.

Site Prep and Foundation Work

Before any unit goes up, the ground underneath has to be right. That includes grading, drainage planning, foundation or pier placement, and utility trenching for water, sewer, and power. Benson coordinates all of it with a written scope and photo documentation so you can see exactly what’s happening under the slab before it gets covered.

Permitting and Plans

Most cities require specific ADU permits, and the rules vary by neighborhood. Benson’s team prepares the plans and handles the submittals, so that part of the project doesn’t stall. You’ll get a written timeline and updates as the permit moves through review rather than a vague “we’re working on it.”

Utility Connections and Finishing

The final stretch connects the unit to electric, water, sewer, and gas where applicable, then finishes the interior to a livable standard. That includes trim, paint, flooring, fixtures, and appliance hookups. Benson photographs every stage, so you have a record of what’s behind the walls long after the final walkthrough.

Why Homeowners Choose the Relay Home Co. Family

Relay Home Co. was founded in 2010 with a simple observation: home service was stuck in the past while everything else had moved onto your phone. The name comes from a relay race, the clean hand-off from one runner to the next so nothing gets dropped, and from the small switch that makes a connection the moment you need it. Every independent local business in the family, including Benson ADU Builders, signs on to The Relay Standard: book in a tap instead of playing phone tag, give a live arrival time instead of a four-hour window, send photo updates before and after, and put the price in writing before anything starts. The Relay Visibility Guarantee means exactly that: you know who is coming, when they will arrive, what it will cost, and what’s happening while the work is underway. Benson brings something else rare in the ADU world: access to the industry’s top prefab brands and James Hardie materials, so you choose from curated options instead of whatever the contractor happens to stock. And if anything is not right within a full year, the 365-Day Done Right Promise means Benson makes it right, no fine print and no debate.
