Benson ADU Builders in Colorado
Benson ADU Builders brings accessory dwelling units and home additions to Colorado homeowners through the Relay Home Co. family, established in 2006. We build with prefab brands Colorado residents can research independently: Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed, finished with James Hardie cladding. Every project carries The Relay Visibility Guarantee. That means a written price before any work starts, real-time tracking from your phone, and a 365-Day Done Right Promise stamped on every job. No verbal estimates that drift. No scope creep billed after the fact.
Why Colorado Homeowners Choose Benson ADU Builders
Colorado homeowners, especially those adding an ADU for aging parents, rental income, or a dedicated workspace, want the same transparency from a contractor that they expect from a rideshare app. You should know who is on your property, when they will arrive, and exactly what the work costs before it begins. That is how we operate. Our technicians are background-checked and uniformed, so the person at your door is someone you can verify. We put the price in writing from the first conversation, not after demo day. And when you build with us, you get access to the industry’s leading prefab manufacturers, curated options instead of a single take-it-or-leave-it product. Phone-first homeowners in Colorado do not tolerate a price that changes at the door. Neither do we.
Backed by the Relay Home Co. Family
Every Benson ADU Builders location is independently owned and operated under The Relay Visibility Guarantee, including Benson ADU Builders in Connecticut - ADU projects. When you hire us in Colorado, you get the full weight of the Relay Home Co. family behind the project: a written guarantee, a free second visit if any covered repair fails, and a live person answering the phone around the clock, every day of the year. The 365-Day Done Right Promise means if the work is not right within a full year, we make it right. That is the standard, wherever the project is.
How Prefab ADUs Work for Colorado Homeowners
A prefab ADU is built in a controlled factory setting, then delivered and assembled on your property. For Colorado homeowners, this approach shortens on-site construction time and reduces weather delays, which matters when snow and freeze-thaw cycles can stall traditional builds. You are not assembling stick framing in a muddy backyard for six months. Instead, you choose from vetted manufacturers, we handle the site work, foundation, and utility connections, and the home arrives in modules or panels. The brands we build with, Abodu for backyard units, Cover for panelized designs, Dvele for high-performance envelopes, Mighty Buildings and Boxabl for modular options, Plant Prefab for architect-designed homes, and Tuff Shed for simpler studio structures, each bring a different strength to Colorado’s climate and lot conditions. We help you match the right system to your property, budget, and intended use.
What Does an ADU Cost in Colorado?
Prefab ADU costs vary widely by size, manufacturer, site conditions, and utility work. A simple backyard studio from Tuff Shed can start in the low five figures, while a fully finished one-bedroom from Abodu or Cover typically runs higher once site work, permits, and connections are included. High-performance homes from Dvele or custom Plant Prefab designs command premium pricing. Rather than hand you a vague verbal range, we give you a written price for your specific project before any work starts. That price is quoted and agreed before anything begins, so the invoice matches the quote. Two Colorado projects rarely cost the same, because lot slope, soil conditions, and utility access all shift the number. That is exactly why a written quote matters.
Can You Build an ADU on My Colorado Property?
Most Colorado municipalities allow ADUs in some form, but local zoning codes, setback requirements, and lot size minimums vary from one jurisdiction to the next. Some areas cap ADU square footage as a percentage of the primary home. Others require owner occupancy on the property. Before we quote your project, we review your lot against local requirements so the price you see reflects what is actually buildable. You do not need to decode the zoning code alone. We walk you through what your property qualifies for and which manufacturers fit within your local constraints.
Does the Price Change Once You See the Property?
No. We quote the job in writing before we start, and we stand behind that number. If site conditions reveal something unexpected during construction, we discuss it with you before any additional work proceeds. You approve it in writing first. This is the core of The Relay Visibility Guarantee: no surprises at the door and no scope creep billed after the fact. The 365-Day Done Right Promise backs the workmanship, and if a covered repair fails within the year, we return for a free second visit to make it right.
What Brands Do You Build With?
Benson ADU Builders is authorized to build with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed. We finish exteriors and accents with James Hardie fiber cement cladding, a material well suited to Colorado’s sun exposure and temperature swings. These are not obscure names. You can research each manufacturer independently, read their specifications, and understand exactly what you are getting before you commit. We would rather you research and feel confident than trust a single sales pitch.

Benson ADU Builders operates the same way across Colorado and in other regions like Benson ADU Builders in Delaware - ADU: book in a tap, get a live arrival time, see photo updates of the work before and after, and pay from a digital invoice.

Frequently Asked Questions
Prefab ADUs typically complete faster than stick-built additions because much of the construction happens in a factory while site work proceeds on your property. The total timeline depends on permitting, foundation work, utility connections, and the manufacturer you choose. We give you a clear schedule in writing before any work starts, so you know what to expect from day one. Call us for a timeline specific to your project.
We handle the permitting process for your ADU project, including zoning review and building permits. Local requirements vary across Colorado, and we manage the paperwork so you do not have to navigate it alone. Every price we quote includes the work required to get your project permitted and built correctly.
