Boulder Construction Defect Lawyer | Hollington Law Firm

Boulder is one of Colorado's most demanding places to build a home. The city's mix of historic districts, hillside lots, expansive soils, aggressive energy-efficiency codes, and post-Marshall Fire rebuild activity creates more ways for a construction project to go wrong than almost any market in the state. When something does go wrong — foundation movement on a Table Mesa hillside, water intrusion behind modern siding in North Boulder, retaining-wall failure on a Chautauqua lot — Boulder homeowners need a construction defect lawyer who understands both the geology and the code regime.

Hollington Law Firm represents Boulder-area homeowners in construction defect matters from Mapleton Hill to Gunbarrel to the Marshall Fire rebuild communities in Louisville and Superior. This page explains what makes Boulder defect cases different and the specific issues we see most often.

Why Construction Defects in Boulder Are Different

Boulder is not a tract-home market. The defect issues that show up here look less like volume-builder pattern claims and more like complex single-build failures driven by site conditions, design choices, or specialty materials.

Boulder's Diverse Housing Stock

Boulder housing breaks into several distinct categories, each with its own defect profile:

• Historic homes dating from the late 1800s through the 1930s in Mapleton Hill, Whittier, University Hill, and Goss-Grove — often with original stone or brick foundations, balloon framing, and updates layered over many decades

• Mid-century single-family in Martin Acres, Table Mesa, and South Boulder — many built on expansive soils with foundation systems that no longer meet modern geotechnical standards

• Hillside and foothill homes in Chautauqua, Devil's Thumb, Pine Brook Hills, and the Flatirons foothills — requiring caissons, grade beams, retaining walls, and engineered drainage

• Contemporary green and passive-solar builds in North Boulder, Holiday, and Gunbarrel — using innovative cladding, insulation, and ventilation systems that sometimes outrun installer training

• Marshall Fire rebuilds in Louisville, Superior, and unincorporated Boulder County — new construction completed under unusual time pressure and supply-chain conditions

Each category fails differently. A defect lawyer who treats them all the same will miss the underlying cause.

Boulder's Building Code Regime

Boulder enforces some of the strictest building codes in Colorado, including:

• Aggressive energy-efficiency requirements that have outpaced the IECC base code for more than a decade

• Landmark and historic-preservation overlays in several neighborhoods, restricting alterations and dictating materials

• Hillside development standards controlling cuts, fills, and structural design

• Wildland-urban interface (WUI) requirements for properties in the foothills

When a builder cuts corners, the violation is not just a code violation — it's often a deviation from the specific contract documents and approved plans, which strengthens the construction defect claim.

Boulder's Soils and Slopes

The eastern part of Boulder, including Table Mesa and South Boulder, sits on expansive clay soils comparable to the worst of the Denver Metro. The western edge of the city and the foothills involve slope stability and landslide-susceptible terrain mapped by the Colorado Geological Survey. Foundations that work in flat tract construction frequently do not work here without site-specific geotechnical design.

Common geotechnical-driven defects:

• Slab heave from inadequate moisture control under slabs on expansive soils

• Foundation settlement on under-sized caissons or improperly bored piers

• Retaining wall rotation or failure from missing drainage or inadequate reinforcement

• Grade-beam cracking where loads were not properly distributed to caissons

• Drainage failures channeling water toward the foundation in sloped lots

Common Construction Defects We See in Boulder Homes

Patterns across the Boulder caseload:

Water and envelope

• Hidden water intrusion behind rainscreen systems and modern siding

• Stucco and EIFS failures where flashing was incorrectly detailed at penetrations

• Window and door flashing defects on contemporary designs with minimal overhangs

• Roof flashing failures, particularly at parapets, skylights, and roof-to-wall transitions

• Inadequate vapor management causing condensation inside high-performance wall assemblies

Structural and geotechnical

• Foundation movement on expansive soils and hillside lots

• Insufficient or absent caissons on sites that called for them

• Improper grading and drainage causing foundation saturation

• Retaining wall and grade-beam failures

• Removed or compromised load-bearing elements in historic-home remodels

Green building and energy systems

• Insulation gaps causing thermal bridging and condensation

• Mechanical ventilation systems (ERVs, HRVs) installed without proper commissioning

• Passive-solar designs with shading or thermal-mass problems

• Solar PV penetrations creating roof leaks

• Radiant-floor failures from poor manifold layout or unprotected tubing

Historic and remodel work

• Structural alterations performed without permits or engineering

• Galvanic corrosion from mixed-metal repairs in older homes

• Foundation underpinning that introduced new movement

• Lead, asbestos, or hazardous-material issues uncovered mid-remodel and improperly handled

Marshall Fire Rebuilds: A Special Category

The December 2021 Marshall Fire destroyed approximately 1,084 homes in Louisville, Superior, and unincorporated Boulder County. The rebuild that followed has now been under construction for more than four years, and defect issues are beginning to surface as the earliest rebuilds pass their builder-warranty windows.

Rebuild-specific defect patterns:

• Foundation work performed in winter conditions without adequate temperature controls

• Framing materials substituted under supply-chain shortages

• Mechanical and electrical work performed by trades stretched thin across hundreds of simultaneous projects

• Drainage and grading completed before adjacent lots were finished, then disturbed by subsequent construction

• Insurance-proceeds disputes intersecting with builder workmanship issues

Marshall Fire homeowners often face a layered claim: the insurance recovery, the builder's contract performance, and any independent construction defects. The deadlines for each track run separately.

Your Legal Rights as a Boulder Homeowner

Colorado's Construction Defect Action Reform Act, C.R.S. §§ 13-20-801 through 13-20-808 governs construction defect claims throughout the state, including Boulder. CDARA imposes a specific pre-litigation sequence.

The Notice of Claim Process

Before filing a construction defect lawsuit, a Boulder homeowner must serve a Notice of Claim on the builder, contractor, or design professional under C.R.S. § 13-20-803.5. The notice triggers:

• A 30-day inspection period for the builder

• A 60-day offer period in which the builder may offer repair, payment, or both

• The homeowner's election to accept, reject, or treat the offer as inadequate

Suing without first serving a proper Notice of Claim can result in dismissal and loss of fee-shifting protections. The notice itself must describe the alleged defects with reasonable specificity, which is one reason early involvement of qualified experts matters.

Statutes of Limitations and Repose

Under C.R.S. § 13-80-104, Colorado imposes:

• A two-year statute of limitations running from discovery of the defect, and

• A six-year statute of repose from substantial completion, extended to eight years if the defect manifests in the fifth or sixth year

For Boulder homeowners, the discovery question is often complicated by gradual symptoms — hairline cracks that widen over years, drywall pops attributed to "settling," or moisture odors that come and go with the seasons. Documentation of when each symptom first appeared can determine whether a claim is timely.

HOA and Common-Interest Community Claims

Boulder County has a substantial inventory of HOA-governed townhomes and condominiums. Under Colorado law, HOA-level defect actions involving common elements are subject to additional procedural requirements — including owner-vote and disclosure provisions added by HB 17-1279 — that do not apply to individual single-family claims. A Boulder homeowner in an HOA-governed community should understand which track applies before serving any notice.

Where Boulder Cases Are Filed

Boulder County construction defect cases are filed in the District Court for the 20th Judicial District at the Boulder County Justice Center. Cases involving property in Broomfield County are filed in the 17th Judicial District, and Marshall Fire rebuild cases in Superior fall into Boulder County despite Superior straddling the Boulder–Jefferson County line — the legal property description controls.

Arbitration clauses are common in Boulder builder contracts, particularly with regional and national volume builders active in the rebuild market. Whether an arbitration clause is enforceable, and what its limits are, is one of the first questions a Boulder construction defect lawyer evaluates.

What to Do If You Suspect a Construction Defect in Your Boulder Home

The sequence matters — both for preserving evidence and for protecting the legal claim.

1. Document everything with dates. Photos of cracks, water staining, sloping, separations, and any related symptoms; service requests; builder communications; HOA correspondence; warranty submittals.

2. Do not perform invasive repairs yet. Drywall patches, stucco work, or foundation underpinning before the defect inspection can destroy the evidence needed to prove cause.

3. Pull the records. Closing documents, builder warranty, geotechnical reports, original plans and specifications, Boulder or Boulder County building permits and inspection cards, HOA disclosures, prior real-estate inspection reports.

4. Get a defect-focused inspection. A real-estate inspection is not designed to identify construction defects. We coordinate with structural engineers, geotechnical engineers, building envelope consultants, and other specialists matched to the symptoms.

5. Consult a Colorado construction defect attorney. The CDARA deadlines, the statute of repose, and any contract-based notice or arbitration triggers can all be running at the same time. Early counsel preserves the most options.
