Fee-only ADU & small-infill feasibility advisory

Find out if your ADU build is feasible before you spend the money.

Civic Infill Works gives Northern Colorado homeowners, small property owners, and public, nonprofit, and institutional partners a first read on whether a backyard cottage, garage apartment, basement unit, or other type of accessory dwelling unit (ADU) is worth pursuing. The work combines local policy fluency, private and public funding navigation, and construction-cost reality checks before you hire a designer, contractor, or lender.

What Civic Infill Works does

Civic Infill Works is a Northern Colorado-based, fee-only feasibility and implementation advisory for ADUs and small infill projects. It sits between the planning counter, the utility question, the construction estimate, the funding path, and the final decision. The goal is not to sell you a plan set, a prefab unit, a construction contract, or financing. The goal is to help you decide what to verify next, what might stop the build, and whether the opportunity is strong enough to justify deeper due diligence.

How Civic Infill Works gets paid is straightforward: clients pay a scoped advisory fee. Civic Infill Works does not rely on undisclosed referral fees, and clients are not required to hire a specific builder, lender, designer, or product vendor after the feasibility work.

Policy-to-parcel translation that turns city, county, and state-level ADU rules into a practical read on one real property.
Parcel-specific first read on zoning, site fit, access, utilities, and the hidden constraints that often surface too late.
Written feasibility memo outlining likely process, cost exposure, decision points, and the questions that could change the build.
Funding-path analysis for projects that may fit mission-aligned capital, CDFI lending, CRA-motivated bank support, vouchers, LIHTC-adjacent partnerships, subsidies, or other public/private funding sources when clients are willing to accept the restrictions that come with them.
Public implementation support for municipalities, counties, and mission-driven partners trying to turn state or federal statutes, grant language, and program requirements into a workable local ADU strategy.
Integrated construction reality check through Alpine West Construction & Restoration, including cost estimates, materials pricing, and build-path input when a client wants implementation support.
Implementation sequencing that clarifies which professional to call next, in what order, and what each call needs to answer.

Why this is hard

An ADU looks simple from the outside: a small home tucked onto a lot that already has a house. In practice, it is a coordinated feasibility puzzle: zoning, utilities, access, construction, financing, ownership goals, and operations all have to fit in the right order. One overlooked constraint can change the budget, the timeline, or whether the build is worth pursuing at all.

Code allowance is not buildability

“Allowed somewhere in the code” is not the same thing as “your lot is ready to build.” Setbacks, lot coverage, easements, overlays, and plat notes can disqualify a project that looks fine on paper.

Utilities are an early gate

Water, sewer, septic, and electric capacity can turn a small structure into a costly one. Service upgrades, trenching, or septic capacity often need to be verified before design.

Most cost lives outside the building

Site work, fees, financing, design, contingency, and operations stack up. A construction estimate is not a budget.

Most homeowners hire in the wrong order

Paying for design before answering the zoning, utility, access, and budget questions is the most common avoidable mistake.

Who it helps

Homeowners

Considering an ADU, including a backyard cottage, garage apartment, basement unit, or other small secondary home — for family, aging in place, or rental income.

Small developers & investors

Property owners who understand rental operations but need zoning, site, utility, funding, and construction-feasibility triage before spending serious money.

Realtors & lenders

Trusted advisors whose clients keep asking whether a parcel can support a second unit, and who want a clear, fee-only answer to point to.

Municipalities & counties

Public-sector teams trying to understand the statute, funding source, local code path, partner roles, and practical steps required to make ADU implementation real.

Nonprofits & institutions

Housing, education, health, and community partners exploring whether ADU-style approaches can support caregivers, students, staff, or mission-aligned infill.

Local employers

Businesses and anchor employers looking for practical workforce-housing options that fit local rules, available partners, and real construction constraints.

Feasibility pathways

Start with the level of help your decision actually needs. Civic Infill Works can begin with a parcel-specific first read, a written feasibility memo, a finance-readiness screen, or a larger implementation conversation for public, nonprofit, institutional, and referral partners.

Examples

Modest, practical infill is the point

The strongest ADU conversations usually are not about luxury finishes. They are about whether a small unit can fit the parcel, budget, utilities, access, financing path, and long-term use without surprising the owner too late.
