ADU construction is how homeowners add a second living space on the same property as the main house. It might be a rental unit, a guest house, a home gym, or a small space for family like elderly parents who need something private but close. Our team at NS Design & Build take your ideas and turn it into a buildable plan, then manages everything from design and permits through to construction and completion.
ADU projects in Denver usually start with figuring out what the property can actually support and what kind of space makes sense long-term.
From there, the focus shifts to layout, zoning requirements, and how the unit will function day to day. Each project moves through design, permitting, and construction with the goal of creating a usable second living space that fits the property and complies with local building codes.
Services include:
ADU projects are handled with a clear understanding of Denver zoning code changes, permits, and city requirements.
ADUs are designed to improve property value, increase equity, and support long-term investment goals like rental income or added living space.

Everything starts on-site with a look at the property, zoning rules, and what the lot can realistically support. Budget, intended use, and layout ideas are all discussed at this stage, so the direction is clear early.

Everything gets built around Denver zoning rules, building codes, and the specific ADU type. Layout, utilities, bedroom setup, and permit approvals all move in parallel as the project gets shaped for approval.

Once approved, construction moves through framing, plumbing, electrical, and finishing work in sequence. The project wraps after inspections and final checks confirm the space is ready to use.

Yes. Most ADU construction projects increase property value, improve equity, and can generate rental income depending on use and location within Metro Denver.
ADU projects must follow Denver building codes, fire code requirements, zoning regulations, and city council guidelines. Permits are required before construction begins, and we can help you organize that.
Yes. Most ADU construction projects use existing structures like basements or garages, or build detached units depending on zoning, lot size, and property conditions.
Timelines vary based on design, permits, and how complex the ADU is. Most delays come from approvals and scope changes rather than construction itself.
