How to Build an ADU with a Denver ADU Builder

In today’s real estate landscape, homeowners are looking for creative ways to add value, flexibility, and functionality to their properties. One of the most effective and in-demand solutions? Accessory Dwelling Units, or ADUs. These independent living spaces provide homeowners with expanded options—whether that’s extra room for family, space for guests, or income through rental opportunities.

As a Denver ADU builder, Sustainable Design Build (SDB) is here to help you navigate the process of building an ADU, from zoning to finishes, and show you how your project can be both functional and luxurious.

Why Build an ADU in Denver?

Denver’s housing market is tight, but ADUs offer flexibility without requiring the purchase of new land. Whether you’re planning a cozy backyard cottage or converting a garage into a livable space, an ADU allows you to:

• Host guests or family members in comfort

   

• Generate rental income

   

• Age in place or provide housing for aging parents

   

• Increase your property value

   

With updated zoning laws and a growing demand for creative housing solutions, there’s never been a better time to partner with a qualified Denver ADU builder like SDB.

Types of ADUs You Can Build

There are several different types of ADUs allowed in Denver, each suited to different property configurations and homeowner needs:

Detached ADUs are especially popular for homeowners who value privacy—perfect for rental units, guest suites, or even a dedicated office or studio space.

Custom Luxury ADUs Exist Too

At Sustainable Design Build, we don’t just build ADUs—we craft elevated, custom luxury ADUs tailored to your vision. Whether you want a high-end guest retreat with top-of-the-line appliances or a modern studio with luxury finishes, our team brings creativity and craftsmanship to every detail.

Your ADU doesn’t have to feel like an afterthought or a basic solution. With smart design, architectural integrity, and premium materials, we’ll make sure your ADU stands out—while still integrating beautifully with your primary residence.

Custom features can include:

• Vaulted ceilings and large windows for natural light

   

• Designer kitchens and spa-inspired bathrooms

   

• Radiant floor heating, smart home integrations

   

• High-end siding, roofing, and exterior finishes

   

• Private patios or rooftop decks

   

Let’s turn your vision into a space that feels like home—for you, your guests, or your tenants.

What Are the Zoning Rules for ADUs in Denver?

Building an ADU in Denver requires compliance with specific zoning laws. Here’s what to consider before breaking ground:

• Zoning Verification: Check if your lot is in a zone that allows ADUs. Use the Denver ADU Zoning Map to search your address.

   

• Size & Height Limits: ADUs must meet height, square footage, and setback requirements based on your lot and zoning district.

   

• Design Consistency: The ADU must visually complement your primary home.

   

• Utility Connections: Water and electrical systems are typically shared with the main house.

   

• Access Requirements: Must include proper pedestrian access, often from an alley or street frontage.

   

• Rental Licenses: Planning to rent your ADU? You’ll need a certificate of occupancy and a rental license.
