What an ADU or backyard cottage involves

An accessory dwelling unit (ADU), sometimes called a backyard cottage, is a secondary living unit on a lot that already has a primary home. Common forms include detached backyard cottages, garage conversions, and attached additions with a separate entrance and living space. In the Denver metro, feasibility usually turns on zoning and lot standards, utility capacity, access and parking rules, setbacks, height limits, and how the unit will be used (long-term housing, multigenerational living, or flexible guest space). Early planning should confirm what your city or county allows on your specific parcel before design is locked in.

text

Design and site factors that drive the project

Strong ADU plans start with the lot, not just the floor plan. Key inputs include buildable area after setbacks, existing structures and easements, grading and drainage, tree and landscape impacts, alley or side-yard access, and where water, sewer, gas, and electric can connect. Interior planning typically covers a compact kitchen, full or three-quarter bath, sleeping space, storage, daylight, and code-required egress. Exterior design should fit the primary home and neighborhood context while meeting height, lot coverage, and exterior material standards set by the local jurisdiction. Detached units also need clear decisions on foundation type, insulation and energy detailing for Colorado’s climate, and durable exterior assemblies that handle freeze-thaw cycles and sun exposure.

text

Permits, inspections, and trade coordination

ADU projects generally require building permits and may also need zoning review, utility permits, and separate trade permits. Requirements vary by city and county across the Denver metro, so the submittal package should match the rules for the property address. A municipally licensed Denver general contractor coordinates the overall project and works with licensed specialty trades for work such as electrical, plumbing, and mechanical systems. That coordination covers sequencing, inspection readiness, and keeping architectural, structural, and MEP details aligned as the unit moves from plans to construction.

text

Typical build path

Most ADU projects follow a clear sequence: feasibility and code check, measured site review, schematic design, construction documents, permit submittal, procurement, construction, inspections, and closeout. Detached cottages often involve site work, foundation, framing, roofing, windows, insulation, drywall, finishes, and final utility tie-ins. Garage conversions and attached ADUs can reduce some site work but may add structural, fire-separation, moisture, and existing-condition challenges. Conversion projects need careful assessment of foundation, framing, insulation, head height, and whether the existing shell can support a comfortable, code-compliant dwelling.

text

What influences cost without a one-size price

ADU cost is project-specific. Major drivers include unit size, detached versus attached or conversion scope, foundation and site work, utility run lengths and capacity upgrades, kitchen and bath layout, finish level, structural complexity, energy detailing, access constraints, and local permit requirements. Soft costs also matter: design and engineering, survey or site documentation when needed, permit fees, and longer lead times for selected materials. A clear scope and early utility/site review usually reduce redesign and change orders later.

FAQ

Common questions

What is the difference between an ADU and a backyard cottage?

They often describe the same idea: a secondary dwelling on a lot with a primary home. “Backyard cottage” usually means a detached unit behind the main house. “ADU” is the broader planning term and can include detached units, attached units, or conversions, depending on local definitions.

Who handles the trade permits and licensing on an ADU project?

A municipally licensed Denver general contractor coordinates the project and the permit path. Licensed specialty trades perform regulated trade work such as electrical, plumbing, and mechanical, and those trades pull the permits required for their scopes where applicable.

Can every Denver-metro lot add an ADU?

No. Eligibility depends on local zoning and lot standards, including use rules, setbacks, height, lot coverage, parking, and utility constraints. The right first step is confirming what the jurisdiction allows for the specific address and lot configuration.

Is a garage conversion simpler than a new detached cottage?

Sometimes, but not always. Conversions may reuse an existing shell and reduce some site work, yet they can require structural upgrades, insulation and moisture improvements, fire separation, ceiling-height solutions, and new utility routing. A detached cottage adds foundation and full exterior scope but can offer a cleaner layout when yard space and setbacks allow.

How long does an ADU project usually take?

Timeline depends on design complexity, utility work, permit review duration, material lead times, weather, and inspection scheduling. Projects with clear feasibility, complete drawings, and fewer existing-condition surprises generally move more predictably than conversions discovered midstream to need major upgrades.

What decisions should homeowners make early?

Confirm intended use, target size, detached versus attached or conversion, access and privacy needs, parking implications, budget range as a planning input, and whether the unit must function independently year-round. Those choices shape site layout, utility design, and the permit strategy.

How to start planning

Begin with parcel realities: zoning path, buildable envelope, access, and utility capacity. Then define the unit type and must-have program so design and budgeting stay aligned. From there, construction documents and permit coordination can proceed with fewer revisions. If you are comparing options, bring basic lot information, any prior survey or improvement location certificate if available, rough size goals, and notes on how the unit will be used. That preparation helps a general contractor and design team give a clearer read on scope and sequence.

FAQ

Common questions

Is an ADU allowed on my lot?

It depends on your city’s zoning — lot size, setbacks, and parking rules vary across the metro. We run the zoning check as the first step and tell you what your lot supports before you spend money on design.

Do you handle ADU permits and inspections?

Yes — ADU permitting is municipal, and we manage zoning review, permit application, and every inspection through certificate of occupancy.

Detached, attached, or garage conversion — which is right?

Each has different zoning, cost, and site implications. We design all three and recommend based on your lot, budget, and how you plan to use the unit.

What does an ADU cost?

Getting a real answer costs less than most people expect: an ADU feasibility consultation is $350, and the full ADU feasibility package — zoning check, site analysis, and concept direction — is $950, both listed at fixed prices on our booking page. Construction cost depends on the path: garage and basement conversions reuse existing structure, while a detached backyard cottage is new construction from the foundation up. After feasibility we quote the build itself as a fixed-price proposal, so you know the number before work starts.

How long does an ADU project take?

Three phases run in sequence: design (site measure, concept, construction documents), permitting (zoning and building review, which move on the municipality’s calendar), then construction. Conversions generally move faster than detached new builds because the shell and foundation already exist. We lay out the phase-by-phase schedule in your proposal, and you track progress on our operations platform once work starts.

How small a lot can support an ADU?

Smaller than most people assume — many Front Range single-unit lots that owners write off can carry a detached unit, and each city sets its own minimum lot size, setbacks, and building coverage. Whether your district’s standards leave room for a backyard cottage — or point you toward a garage or basement conversion instead — is exactly what the feasibility check answers for your address.

What is the ADU permit process?

Two municipal reviews run in order: a zoning review confirming the unit fits your district’s standards, then a building permit review of the construction documents, with inspections during the build and a certificate of occupancy at the end. Colorado HB 24-1152 now requires most Front Range municipalities to allow ADUs on single-unit lots, and we confirm how your city implements it as the first step of feasibility.
