Construction projects in Denver can be complex, fast-moving, and heavily regulated. Between managing subcontractors, meeting deadlines, and complying with local codes, even seasoned contractors can make legal mistakes that lead to costly disputes or litigation. Whether you’re a general contractor, subcontractor, or developer, understanding these common pitfalls—and how to avoid them—can help protect your business and reputation.
In this guide, we’ll break down the most frequent construction law errors made in Denver and how the best Denver construction lawyer can help you navigate them before they become serious problems.
1. Failing to Use a Legally Sound Contract
One of the most common mistakes Denver contractors make is relying on verbal agreements or poorly drafted contracts. A handshake deal might feel efficient at the start, but without written terms, you’re left vulnerable if a dispute arises over scope, payment, or delays.
How to Avoid It:
Always use a written contract that clearly defines the scope of work, timelines, payment structure, change order procedures, and dispute resolution clauses. Have every contract reviewed by a legal professional. The best Denver construction lawyer can help you create templates tailored to Colorado’s construction laws, reducing your exposure to liability.
2. Missing Mechanic’s Lien Deadlines
Mechanic’s liens are a powerful tool in Colorado, giving contractors and suppliers the right to claim unpaid work or materials. But if you miss the strict deadlines, you forfeit that right entirely.
How to Avoid It:
Understand the lien timeline under Colorado law: you typically have four months from the last day of work to file a lien on a residential project (and two months to provide notice in some cases). A construction attorney can help you track these deadlines and ensure filings are accurate.
3. Ignoring the CDARA Process for Construction Defects
The Construction Defect Action Reform Act (CDARA) governs how homeowners and contractors handle defect claims in Colorado. If a contractor fails to comply with CDARA’s pre-litigation process, they may lose the opportunity to resolve the issue without going to court.
How to Avoid It:
If you receive a Notice of Claim for a defect, take it seriously and respond within the legal timeframe. The law gives you the right to inspect the property and offer a repair before litigation begins. A legal advisor familiar with CDARA can guide you through the process and preserve your rights.
4. Overlooking Local Building Codes and Permits
Denver has strict building regulations that vary by neighborhood and zoning district. Failing to pull the right permits or comply with code requirements can lead to stop work orders, fines, or even legal claims from property owners.
How to Avoid It:
Before breaking ground, check all permit and inspection requirements through Denver’s Community Planning and Development Department. Staying compliant not only avoids enforcement actions but also limits your liability for future defect claims. When in doubt, consult with a construction lawyer who knows Denver’s local ordinances.
5. Poor Documentation and Recordkeeping
Construction is a document-heavy industry. When disputes arise, what’s on paper matters more than what’s remembered. Many contractors lose leverage simply because they didn’t keep a proper paper trail.
How to Avoid It:
Document everything—change orders, communications, daily logs, inspections, and payments. Use digital tools or apps that help you maintain organized project records. If you do end up in a dispute, having solid documentation can make all the difference in proving your case.
6. Not Addressing Change Orders Properly
Scope changes are common in construction, but if they’re not handled with proper documentation and approval, they can lead to major conflicts about cost, timing, or deliverables.
How to Avoid It:
Include a clear change order clause in your contract. Ensure that all scope changes are approved in writing by both parties before work begins. Don’t rely on verbal approvals or informal texts when the stakes are high. A construction attorney can help enforce change order terms if disputes arise.
7. Using One-Size-Fits-All Contracts
Many contractors download generic contracts from the internet without realizing they don’t meet Colorado’s legal requirements. Worse, these contracts often leave out key protections related to indemnity, risk transfer, or dispute resolution.
How to Avoid It:
Use Colorado-specific contracts that account for state law, licensing rules, lien rights, and CDARA requirements. The best Denver construction lawyer can help tailor your agreements to your exact business model and project type, whether you work on residential remodels or large commercial builds.
8. Misclassifying Workers and Subcontractors
With the growing use of subcontractors and day laborers, many construction businesses accidentally misclassify employees, leading to tax issues, fines, or workers’ comp claims.
How to Avoid It:
Know the difference between an employee and an independent contractor under Colorado law. Use written agreements, obtain W-9 forms, and ensure you’re meeting all legal and insurance obligations. An employment or construction attorney can help you set up compliant labor practices.
9. Ignoring Insurance and Bond Requirements
Many Denver contractors either carry insufficient insurance or don’t understand their policy exclusions. Others fail to meet bonding requirements for public projects, which can disqualify them from bidding or result in penalties.
How to Avoid It:
Review your general liability, builder’s risk, and subcontractor coverage annually. For bonded work, confirm you meet the surety’s requirements well in advance. A construction lawyer can review your policies and advise you on risk management strategies.
10. Waiting Too Long to Call a Lawyer
Contractors often wait until a dispute explodes before contacting legal counsel—by then, the damage may be done. Whether it’s a payment delay, permit issue, or defect claim, early legal guidance can help you avoid litigation entirely.
How to Avoid It:
Build a relationship with a legal advisor before problems arise. The best Denver construction lawyer will help you spot risks early, resolve disputes efficiently, and position your business for long-term success.
