Building a custom home along the Front Range is one of the most significant investments you will make. Between Denver's expansive clay soils, the hail and UV that punish exterior materials, snow loads, the lack of a statewide general contractor license, jurisdictional differences between Cherry Hills Village, Greenwood Village, Castle Pines, and the foothills communities, and HOA architectural review, there is more to get right here than in most markets.
The difference between a project that goes smoothly and one that does not almost always comes down to what was asked, confirmed, and documented before construction began. Items marked with a warning indicator deserve a direct conversation with your builder before moving forward. Your progress saves automatically.
The builder you choose has more influence over the outcome of your project than any other decision you make. These items help you identify who is qualified, accountable, and the right fit before a single dollar changes hands.
Licensing & Insurance
Confirm the builder holds an active contractor license in the jurisdiction where you are building
Colorado does not issue a statewide general contractor license. Licensing is set at the municipal or county level. Denver requires a Class B General Contractor license. Cherry Hills Village, Greenwood Village, Castle Pines, Arapahoe County, and Douglas County each set their own requirements. Verify directly with the building department where your home will be built.
Confirm active general liability insurance and Colorado workers' compensation coverage
Colorado requires workers' comp for any contractor with employees. Request a current certificate of insurance that names you as additionally insured for the duration of the project.
Ask what written warranty the builder offers, and whether it is builder-backed or a third-party policy
Colorado's Construction Defect Action Reform Act (CDARA) sets statutory rights for defect claims. Beyond that baseline, ask whether the builder provides a third-party warranty (such as 2-10 HBW) covering 1-year fit and finish, 2-year systems, and 10-year structural. A third-party policy survives even if the builder closes the business.
Experience & Portfolio
Request references from completed Denver area projects similar in size, scope, and price point to yours
Building in Cherry Hills Village is not the same as building in Castle Pines, and a foothills build in Evergreen is different again. Ask references about HOA review, jurisdictional response times, and how the builder handled site challenges, not just whether the home looks good.
Confirm direct experience in your specific jurisdiction
Cherry Hills Village, Greenwood Village, Castle Pines, Evergreen, Golden, and unincorporated Arapahoe and Douglas counties each have their own permit process, design review, and timelines. A builder who has worked successfully in your jurisdiction knows the people, the process, and the local quirks.
Review the portfolio for projects that match your architectural style, square footage, and finish level
Mountain modern, transitional, traditional, and contemporary all have different detailing demands. Look for projects of similar size and complexity.
Read independent reviews carefully, not just testimonials on the builder's websiteWatch for
Pay attention to how a builder responds to problems, not just whether things went smoothly. Every project encounters challenges. How they are handled is the real signal.
Early Involvement
Ask whether the builder offers pre-construction services including site review, design input, and early budgeting before plans are finalized
Involving a builder during design catches buildability issues, energy code compliance, and cost surprises before they get locked into permit drawings. This is especially valuable when working with the expansive soils common across the Front Range.
Be cautious of builders who will not review your site or drawings until a contract is signedWatch for
A builder who will not engage until money is committed has not assessed your project's specific risks. That is where surprises begin.
In the Denver metro area, your site rarely tells the whole story on the surface. Expansive clay soils, drainage, hail and UV exposure, snow loads, HOA design review, and foothills wildfire designations all shape what gets built and how. These items make sure nothing is left to assumption before design is finalized.
Site & Jurisdiction
Confirm the builder has reviewed your property survey and understands setback, height, lot coverage, and grading limits for your jurisdiction
Requirements differ across Denver, Cherry Hills Village, Greenwood Village, Castle Pines, and surrounding municipalities. Cherry Hills Village requires a one-acre minimum lot and limits building height. Castle Pines has multiple sub-associations with their own architectural control committees. Local rules drive design.
If your lot is in an HOA or architectural review district, confirm the builder has read the covenants and design guidelines before pricingWatch for
Cherry Hills Village, Greenwood Village neighborhoods, Castle Pines Village, Castle Pines North, and most foothills developments have design review boards that approve materials, colors, roof lines, and exterior elevations. ARB-required changes after pricing are common and can be expensive.
Geotechnical & Soils
Confirm a geotechnical investigation will be completed before the foundation is designed
The Denver Front Range is known for expansive clay soils that can swell when wet and shrink when dry. Without proper engineering, slab and foundation movement is common. A geotech report identifies soil conditions, expansion potential, and recommends the right foundation system: typically drilled piers, deepened footings, or a structural floor system over crawl space.
Ask what foundation system is being specified and why
For expansive soils on the Front Range, drilled piers with grade beams or a deep helical pier system is common for high-end custom homes. Post-tensioned slabs are used in some applications. Avoid builders who default to a standard footing without addressing soil conditions.
Confirm whether radon mitigation is being designed into the home from the start
Colorado is rated EPA Zone 1 for radon, the highest risk classification. Almost all new homes in the Denver metro area should include a passive or active radon mitigation system. Building it in during construction is far less expensive than retrofitting later.
Confirm site drainage and grading direct water away from the foundationWatch for
On expansive soils, water near the foundation drives movement. Positive drainage, proper grading away from the structure, gutters and downspouts routed to daylight, and below-grade waterproofing details all matter more here than in many other markets.
Design Coordination
Confirm the builder will work alongside your architect through design development, not just receive completed drawings at the end
Early builder input on materials, systems, and details catches expensive surprises before they are locked into permit drawings.
Confirm all material selections (siding, roofing, windows, flooring, cabinetry, fixtures) are documented in writing before the contract is signed
Verbal selections are nearly impossible to enforce. Written specifications protect you and keep the budget accurate. Class 4 impact-rated roofing, high-performance windows, and exterior materials chosen for UV and freeze-thaw exposure are critical decisions on the Front Range.
Clarify explicitly what is not included in the quoteWatch for
Landscaping, hardscape, driveway, detached structures, swimming pools, low-voltage and audiovisual, window coverings, snow melt systems, and outdoor living features are frequently excluded without being stated. So are water tap fees, plant investment fees, school impact fees, and HOA architectural review fees. Ask for an itemized exclusions list.
Front Range Climate
Confirm the home is designed for Front Range climate exposure: hail, UV, freeze-thaw cycles, snow loads, and dramatic temperature swings
Denver sits at the heart of "Hail Alley," the highest hail incidence in the United States. Class 4 impact-rated roofing significantly reduces insurance premiums and replacement risk. High-altitude UV degrades materials faster than at lower elevations, and freeze-thaw cycles are hard on exterior finishes. Design for the environment.
If you are building in the foothills (Evergreen, Golden, or surrounding higher elevations), confirm Wildland-Urban Interface compliance
Most foothills communities require ignition-resistant construction in designated Wildfire Hazard Areas. This affects roofing, exterior walls, eaves, vents, decking, and defensible space requirements. Snow loads are also significantly higher in the foothills than in the metro area. These costs need to be in the budget from the start.
Worth noting: Denver's expansive clay soils are the single biggest driver of long-term foundation issues in this market. Almost every issue traceable to soils could have been avoided with the right geotech-informed foundation system at the start. Do not shortcut this step.
The contract is where your entire agreement becomes enforceable. A thorough review here protects you through the full length of the project. If something is unclear, ask before signing.
Scope & Pricing
Confirm the full scope of work, all materials and finishes, and all subcontractors are referenced in the contract
Understand whether the contract is fixed-price or cost-plus, and what that means for your exposure if costs change
Fixed-price contracts give you cost certainty but require a complete scope to price accurately. Cost-plus contracts give transparency on actual costs but require trust and oversight. For high-end custom homes, cost-plus with a guaranteed maximum price is common.
Ask how the builder's fee is structured and whether their compensation changes based on how much you spendWatch for
Percentage-of-cost fee structures can create an incentive to spend more. Fixed-fee or capped-fee structures align incentives better. Ask directly and confirm in writing.
Confirm the payment schedule is tied to construction milestones, not calendar dates
Milestone-based draws keep incentives aligned with progress. If you are using a construction loan, confirm the builder's schedule integrates with your lender's draw inspection process.
Review the change order clause carefullyWatch for
Every scope or design change after signing should require a written change order with cost and timeline impacts confirmed before work proceeds. Verbal approvals create disputes at closeout.
Confirm what contingency is built into the budget and what categories it covers
A 10 to 15 percent contingency is reasonable for custom builds. Understand whether it sits with the builder or with you, and what triggers its use.
Timeline & Permits
Confirm the estimated start date, overall construction timeline, and which conditions could cause delays
Permit timelines vary significantly across Denver, Arapahoe County (Cherry Hills, Greenwood Village), Douglas County (Castle Pines), and the foothills counties. Plan check, agency comments, and HOA architectural review are not always sequential. Build that reality into your schedule.
Confirm the builder will pull all required permits, and that permit fees, water tap fees, plant investment fees, and impact fees are either included or clearly identified as owner-paid
Water tap fees from Denver Water and surrounding districts can be substantial. These are commonly owner-paid and not included in a builder's quote unless specifically called out.
Warranty & Mechanics Liens
Confirm written warranty coverage and review what is covered for how long
Beyond CDARA's statutory rights, ask whether the builder provides a third-party warranty policy and request the actual policy document, not just a summary. Common structures include 1-year fit and finish, 2-year systems, and 10-year structural.
Understand Colorado mechanics lien law and how the builder handles lien waivers and retentionWatch for
In Colorado, mechanics liens must be filed within four months of last work performed (two months for residential property on principal contractors). To protect yourself, require conditional lien waivers from the general contractor and all subcontractors with each progress payment, and unconditional waivers with each final draw. Retention (typically 5 to 10 percent) should be withheld and released only after the lien period expires.
Good to know: If your project involves a construction loan, your lender will have their own draw inspection process. Confirm with your builder early that their payment schedule aligns with how your lender releases funds. Misalignment here causes cash flow problems mid-build.
You do not need to be on site every day, but knowing what to look for at each stage keeps the project on track and the builder accountable. These are the moments where attention matters most.
Communication
Confirm your dedicated point of contact during construction and how frequently updates will be provided
Ask who to contact if you have a concern while work is underway
There should be a direct line to a decision-maker, not a message relayed through the site crew.
Construction Milestones
Site prep, grading, and excavation: confirm the building pad, drainage, and grades match the approved civil and grading plans before foundation work begins
On expansive Front Range soils, drainage is structural. Water moving toward the foundation drives soil expansion and foundation movement. This stage matters more here than in many markets.
Foundation: confirm the foundation system (drilled piers, deepened footings, or structural floor) aligns with the geotechnical report, and that required inspections pass before framing
What goes underground is hard to revisit. Get this stage right.
Framing and structural connections: confirm framing inspections pass, hardware is correctly installed, and the structure matches the approved drawings
Colorado follows the IRC and IBC for residential construction. Specific hold-downs, anchor bolts, and shear panel installation are inspected. Make sure it is done right the first time.
Building envelope: confirm weather-resistive barriers, window flashing, and air-sealing details are complete and inspected before exterior cladding is applied
In Denver's freeze-thaw climate, envelope quality drives long-term comfort, energy bills, and durability. Once stucco, stone, or siding is on, flashing problems are hidden and expensive to address.
Mechanical, electrical, plumbing, and any solar or smart home rough-in: confirm all systems inspect cleanly before drywall is closed
This is also when conduit for EV charging, low-voltage, audiovisual, and home automation gets installed. Decisions made now are costly to add later.
Document any deviation from the approved drawings in writing before authorizing the builder to proceedWatch for
Field decisions made verbally and without a change order create disputes at closeout. Anything that changes the approved scope should be in writing.
The final walkthrough is your opportunity to confirm everything was delivered as agreed. Take your time. A thorough review here protects you long after the builder leaves the site.
Finishes & Systems
Confirm all interior and exterior finishes match the approved selections: roofing, siding, stone, flooring, cabinetry, tile, fixtures
Walk every room for deficiencies: incomplete paint, damaged trim, gaps at transitions, hardware that does not operate correctly
Watch the builder operate all mechanical and electrical systems live: HVAC, plumbing, electrical panel, water heater, radon mitigation, any solar, EV charging, automation
Do not accept handoff without a live demonstration of every system, including smart home features, the radon system, and any monitoring apps.
Inspect the exterior roofing, gutters, downspouts, drainage, and any snow management features
Snow management and gutter performance matter on the Front Range. Confirm everything is properly installed and tested.
Documentation
Receive the final building inspection sign-offs and Certificate of Occupancy before moving in
Receive all equipment manuals, warranty documents, and maintenance instructions for HVAC, water heater, appliances, radon system, and any solar or smart home systems
Confirm any outstanding punch list items are documented in writing with a committed completion date before releasing final payment
Do not release the full final payment until unconditional lien releases are received from the builder and all subcontractors and material suppliersWatch for
Under Colorado mechanics lien law, subs and suppliers retain lien rights against your property until properly waived. Conditional waivers should accompany each draw; unconditional waivers should be received at final payment. Retention is typically held until the lien period expires.
Confirm your warranty registration is complete and you have received the full warranty documentation package, including any third-party warranty policy
One more thing: Keep a complete record of all permits, inspections, warranties, and change orders from the project. These documents have real value at resale and will be requested by any future buyer doing due diligence.
