Denver Custom ADU is a Denver-based accessory dwelling unit builder serving homeowners throughout the Front Range. With more than 30 years of construction experience across commercial and community-focused projects — including restaurants, studios, churches, and gathering spaces — the company brings a level of professionalism, organization, and craftsmanship that stands apart in the residential ADU industry.

Led by Matt Brinn, Denver Custom ADU was built around a simple idea: homeowners deserve a construction experience defined by honesty, structure, communication, and accountability.

Built on Commercial Construction Experience

Before focusing on residential ADUs, Matt Brinn spent decades managing complex commercial construction projects that demanded disciplined scheduling, accurate budgeting, and consistent communication.

That background shaped the foundation of Denver Custom ADU’s approach today. Rather than operating like a traditional residential contractor with vague timelines and fluctuating pricing, the company applies commercial-grade systems and project management practices to every backyard cottage and detached ADU project they build.

Through conversations with homeowners and firsthand observation of local ADU projects, Matt recognized recurring frustrations in the industry:

Unclear budgets
Poor communication
Constant change orders
Delayed schedules
Unpredictable project management

Denver Custom ADU was created specifically to solve those problems.

A Transparent ADU Building Process

As a dedicated ADU contractor and granny flat builder, Denver Custom ADU emphasizes transparency at every stage of the project.

Their process is designed to eliminate uncertainty and create a smoother experience for homeowners from design through final construction.

Fixed Budgets and Clear Scope

The company operates on a fixed-budget model tied to a clearly defined scope of work. Homeowners know exactly what is included in the project pricing upfront.

If changes are requested during construction, they are documented and handled transparently — never hidden inside vague invoices or surprise charges.

This commitment is backed by what they call their “No Surprises Guarantee.”

Monthly Billing Based on Completed Work

Rather than collecting large upfront payments, Denver Custom ADU bills monthly based only on completed construction progress. This structure creates accountability and keeps the financial process straightforward for homeowners.

Separate Design and Construction Contracts

To maintain clarity throughout the process, clients sign separate agreements for design and construction phases. This helps homeowners fully understand each stage of the project before moving forward.

Proactive Permitting and Project Management

Permitting delays are one of the most common challenges in ADU construction, particularly in Denver’s evolving zoning environment.

Denver Custom ADU approaches permitting proactively by:

Identifying potential issues early
Preparing coordinated submittals
Communicating directly with plan reviewers
Addressing corrections quickly
Anticipating zoning and review concerns before submission

Their experience managing large-scale commercial projects allows them to move efficiently without sacrificing quality or cutting corners.

Custom ADUs Designed Around the Homeowner

Every project built by Denver Custom ADU is custom-designed to fit the homeowner’s goals, property layout, and architectural style.

Their ADU services include:

Detached ADUs
Backyard cottages
Granny flats
Custom accessory dwelling units
Flexible residential living spaces

Rather than relying on standardized templates or cookie-cutter floor plans, the company focuses on creating functional, personalized spaces tailored to each client’s needs.

Step-Ahead Communication

One of the company’s defining features is what they describe as “step-ahead” communication.

Homeowners are consistently informed about:

Upcoming construction phases
Expected timelines
Noisy work days
Material deliveries
Site access needs
Next project milestones

This level of communication helps reduce stress and allows homeowners to plan around the construction process more effectively.

Bringing Accountability to Residential Construction

Denver Custom ADU combines the structure and professionalism of commercial construction with the personalized service homeowners expect during residential projects.

Their focus on fixed pricing, transparent communication, proactive permitting, and disciplined project management has made them a trusted detached ADU builder in the Denver area.

For homeowners looking to add a backyard cottage, granny flat, or custom accessory dwelling unit, Denver Custom ADU offers a process built around accountability, craftsmanship, and long-term value.
