What is an ADU, and why should I add one to my property?

An accessory dwelling unit, or ADU, is a separate living space built on the same property as your main home. It can be used for family, guests, rental income, a home office, or a private space for aging parents or adult children. A well-built ADU gives you more flexibility, more usable square footage, and can add real value to your property.

Can you help with permits and local code requirements in Arvada, CO?

Yes. We help guide you through the permit and approval process and make sure your ADU project is built to local code requirements. Rules can vary based on lot size, setbacks, utilities, and intended use, so it is important to work with a contractor who understands local construction standards. We make the process clearer and help you avoid costly mistakes.

How much does it cost to build an ADU?

ADU cost depends on the size, layout, site conditions, utility connections, and the level of finishes you choose. A simple garage conversion will cost less than a fully detached backyard cottage. We provide clear estimates and honest recommendations so you understand where your money is going and what options make the most sense for your goals and budget.

How long does an ADU project take?

Most ADU projects take several months from planning to final completion. The timeline depends on design work, permitting, site preparation, utility work, and the type of structure being built. We give you a realistic schedule upfront, keep you updated during the project, and work hard to keep everything moving without cutting corners.

ADU Builders Arvada CO | D-ROC Renovations

At D-ROC Renovations, we build Accessory Dwelling Units (ADUs) for homeowners who want more usable space, more privacy, and more long-term value from their property. An ADU is a smaller secondary living space built on the same lot as your main home. It can be attached to the house, added over a garage, converted from existing space, or built as a detached backyard unit. These spaces are great for family members, guests, rental income, home offices, or private living quarters.

We know that adding an ADU is a big decision. It is not just about adding square footage. It is about creating a comfortable, functional space that fits your goals and works with your home. Our team helps you plan the project carefully so the finished unit feels like a natural extension of your property while meeting local building requirements and practical everyday needs.

What an ADU Can Be Used For

One of the biggest benefits of an ADU is flexibility. Homeowners use these spaces in many different ways depending on their needs now and in the future.

Private suite for aging parents or extended family
Housing for adult children or returning family members
Guest house for visitors
Rental unit for added monthly income
Home office or creative studio
Caregiver housing
Short-term or long-term living space, where allowed

An ADU can give you room to adapt without having to move. It can also increase property value and make your home more useful for years to come.

Types of ADUs We Build

We offer ADU construction solutions based on your lot, your budget, and how you plan to use the space. Every property is different, so we walk you through the best options.

Detached ADUs: A separate structure built away from the main home, often in the backyard. This option offers the most privacy and feels like a standalone home.
Attached ADUs: An addition connected to the existing house. This is a smart option when you want easier utility tie-ins and a more seamless layout.
Garage Conversion ADUs: We can convert certain garages into livable units with bedrooms, bathrooms, kitchens, insulation, windows, and updated mechanical systems.
Basement or Interior Conversions: If your existing home has unused square footage, we may be able to turn that area into a legal and comfortable dwelling space.
Above-Garage or Add-On Units: In some cases, building above an existing garage or adding onto the home creates an efficient use of available space.

What Is Included in ADU Construction

Our ADU projects are built to provide real living comfort, not just extra room. We focus on layout, durability, energy efficiency, and the details that make a smaller home feel open and functional.

Depending on the project scope, an ADU may include:

Full framing and structural construction
Roofing, siding, and exterior finishing
Windows and exterior doors
Insulation and ventilation
Electrical wiring and lighting
Plumbing systems for kitchens, bathrooms, and laundry
HVAC or mini-split heating and cooling systems
Drywall, flooring, trim, and paint
Kitchenette or full kitchen installation
Bathroom build-out with shower, tub, vanity, and fixtures
Bedroom and living area design
Storage solutions and space-saving layouts

Because D-ROC Renovations is also experienced in roofing, siding, windows, and exterior construction, we make sure the outside of the ADU is just as strong and attractive as the inside. That helps the new structure blend well with your existing home and hold up in Colorado weather.

Our Process

We believe a good ADU project starts with clear planning. We take the time to understand what you need, what your property can support, and what improvements will give you the best return.

Consultation: We talk through your goals, budget, timeline, and how you want to use the ADU.
Site Review: We assess the property layout, access, existing structures, and utility needs.
Design and Scope Planning: We help define the size, layout, finishes, and construction approach.
Permitting and Code Considerations: We work through local building requirements, zoning rules, and project specifications.
Construction: Our team manages the build with a focus on quality workmanship, safety, and communication.
Final Walkthrough: We review the completed space with you and make sure the finished result meets expectations.

Throughout the project, we keep communication straightforward. You will know what is happening, what comes next, and what to expect.

Important ADU Planning Factors

ADUs involve more planning than a basic remodel because they are living spaces with their own code, utility, and access needs. We help homeowners think through the details early so there are fewer surprises later.

Lot size and setback requirements
Zoning and neighborhood regulations
Separate or shared utility connections
Water, sewer, gas, and electric capacity
Parking requirements, where applicable
Privacy, access paths, and outdoor space
Energy efficiency and insulation performance
Matching the style of the main home

Our goal is to create an ADU that is practical, code-aware, and built for everyday living.

Why Homeowners Choose an ADU

Many homeowners come to us because they want more options without leaving the home and neighborhood they already love. An ADU can solve space problems while also creating financial and lifestyle benefits.

Adds usable square footage to your property
Creates privacy for family or guests
Supports multigenerational living
Can provide rental income potential
May increase resale appeal and property value
Offers flexible use as needs change over time

When built well, an ADU is more than an addition. It becomes a smart investment in how your property works for you.
