Adu Construction in Aurora, CO
Dreamline Builders Co. designs and builds accessory dwelling units for homeowners across Aurora, Colorado, from Saddle Rock to the Aurora Highlands. We’re a bonded and insured design-build crew, not a sales office, so the people quoting your ADU are the same ones pulling permits and coordinating the trades on site.
Our shop, our crews, and most of our projects are all in town.
ADU construction for Aurora homes
Aurora’s lot sizes and setback rules vary block by block, which matters a lot once you’re planning a detached ADU. A quarter-acre lot in Tallyn’s Reach gives you more room to work with than a tighter infill lot near Del Mar Circle, and we size the unit and site plan to what your lot and the city’s zoning code actually allow. We also build for Colorado’s climate at altitude: deeper frost-depth footings, properly vented roof assemblies for heavy spring snow loads, and insulation packages that hold up through our wide temperature swings.
Most Aurora ADU projects we take on fall into three types: detached backyard units, garage conversions, and attached additions with a separate entrance. Each has different utility tie-in and egress requirements, and we walk you through which option fits your lot, your budget, and whether you’re building for a rental, a parent, or adult kids. We price the job as a fixed scope before work starts, so you know the number going in.
Permits and approvals in Aurora
Aurora requires a building permit for any ADU, plus a zoning review to confirm lot coverage, setbacks, and parking requirements are met before the city issues approval. If your property sits near the Arapahoe, Adams, or Douglas county line, we double-check which jurisdiction’s utility and septic or sewer rules apply, since Aurora spans all three counties and the requirements aren’t identical. We handle the permit submittal, plan revisions, and inspection scheduling ourselves as part of our ADU and addition construction services, so you’re not the one chasing down the city.
HOA review adds another layer in many Aurora communities. Southlands and Saddle Rock both have design guidelines covering exterior materials, roof pitch, and unit placement that go beyond what the city requires, and we submit those applications alongside the municipal permit so timelines run in parallel instead of back to back. If you’re weighing an ADU against a different kind of project, our main Aurora construction page covers the full range of work we do locally, and homeowners adding a kitchenette to their ADU often start with our Aurora kitchen remodeling page for layout and appliance ideas.
Neighborhoods we serve in Aurora include Southlands, Saddle Rock, Tallyn’s Reach, Aurora Highlands, Murphy Creek, and Green Valley Ranch-adjacent areas on the city’s eastern edge.
ADU Construction FAQs - Aurora
Aurora treats an ADU as its own permitted structure, so you’ll need a dedicated building permit and zoning sign-off separate from any work on your primary house.
It depends on your lot’s size, existing coverage, and setback lines, which is why we start every quote with a site visit and a review of Aurora’s zoning rules for your specific parcel.
Yes, most HOAs in those communities review exterior design, materials, and placement separately from the city, and we submit that paperwork alongside your building permit to keep the project moving.
We build footings to local frost depth, frame roofs to handle heavy spring snow, and spec insulation for Aurora’s big day-to-night temperature swings so the unit stays comfortable and the foundation holds up long term.
