Is $291k enough to open a Colorado demolition company?
The Base case is deliberately not tied to one metro. Statewide labor anchors come from current BLS/O*NET construction wages; occupancy is a three-market Colorado contractor-yard basket; disposal uses a three-jurisdiction public landfill basket; fuel uses the Rocky Mountain diesel series as the closest published weekly benchmark. Regulatory claims are driven by Colorado and federal rules, while local demolition permits are explicitly treated as address-dependent. Colorado does not license general contractors as one uniform statewide profession; the Department of Regulatory Agencies notes that general contractors are among occupations not licensed at the state level, while local governments may regulate them. Colorado DORA licensing guidance.
Startup scope
Where the $476k Typical project cost goes in Colorado
The startup model separates full project cost from founder cash. The Typical column assumes a used 18 – 22 ton excavator with demolition thumb, a used compact track loader, attachments, a service pickup, barriers and small tools. The equipment amount is a modeled procurement allowance that needs live dealer inspection and financing quotes; an August 2026 Colorado dump-truck observation was about $114,500, illustrating how quickly an owned hauling fleet can add six figures. This canonical case avoids that extra fleet by subcontracting transport. The Colorado Secretary of State currently lists $50 for LLC Articles of Organization and $25 for the Periodic Report. Colorado business organization fee schedule.
| Use of funds | Lean | Typical | Premium |
|---|---|---|---|
| Yard deposits, fencing and setup | $12,000 | $18,000 | $32,000 |
| Equipment, pickup, attachments and tools | $78,000 | $285,000 | $440,000 |
| Registrations, permits and professional setup | $7,000 | $11,000 | $18,000 |

Typical startup composition – Colorado statewide model, 2026 USD
Typical funding bridge. The model assumes a $185,250 equipment loan – 65% of the $285,000 equipment/vehicle package – funded at closing. That leaves $290,750 of permanent founder equity. The modeled loan is 9.5% APR, 60 months, about $3,891 per month; it is a planning assumption, not a lender quote. Because there is no assumed landlord allowance, grant, rebate or delayed reimbursement, peak interim founder cash is also about $291,000. A lender that funds after purchase rather than at closing would increase interim cash materially.
The $28,000 net-working-capital line is distinct from the $70,000 reserve. It represents the modeled receivables/prepaid operating cushion net of trade payables; opening inventory is immaterial for this service model and is not counted twice. The reserve is unrestricted cash for ramp losses and permit delays. With a $40,000 minimum closing-cash floor, the Base ramp reaches a maximum modeled cumulative passive-basis cash deficit of about $26,600; $66,600 would mathematically cover the deficit plus floor, so the model rounds up to $70,000.
Critical path
Why asbestos and local permits control the Colorado launch clock
Forming the LLC is not the hard part. The actual opening constraint is getting from “company exists” to “employees may legally and safely start demolition on a permitted structure.” Colorado Regulation 8 requires comprehensive asbestos identification before demolition in covered public-access areas and requires demolition notification at least 10 working days before work, subject to specified exceptions. The rule lists an $80 notice processing fee when the project is not one requiring an asbestos permit, plus a demolition base fee of $50 + $5 per 1,000 square feet or portion of structure footprint. Colorado Regulation 8, Part B, Section III.
| Requirement | Level | Status | Fee / basis | Timing | Dependency |
|---|---|---|---|---|---|
| LLC Articles of Organization | State | Mandatory in model | $50 online | Processing time not modeled as critical path | Before bank, insurance and contracts |
| EIN | Federal | Mandatory for payroll/banking case | $0; IRS | Online availability subject to IRS system | Employer and financial setup |
| Workers' compensation | State | Mandatory with employees | Carrier quote required | Bind before employees work | Payroll and subcontractor controls |
| Pre-demolition engineering survey | Federal | Mandatory before employee demolition | Internal competent person / engineer quote as needed | Before demolition starts | Written evidence required |
| Asbestos inspection and demolition notice | State | Project-specific; frequently mandatory | Inspection quote + applicable $80 notice and $50 + footprint fee | 10 working days notice unless rule exception | Precedes local demolition approval in some jurisdictions |
| Demolition permit / contractor credential | City / county | Varies by address | Varies by city/county; confirm locally | Not published statewide | Zoning, utilities, state environmental signoff may gate issuance |
| Sales tax license | State / home-rule local | Conditional | Needed if making taxable retail sales / retailer-contractor activity | Before taxable sales | Contract structure and local tax jurisdiction |
OSHA also requires utility lines to be shut off, capped or otherwise controlled outside the building line and utilities to be notified in advance. The engineering survey must examine framing, floors, walls and unplanned-collapse risk, with written evidence retained. OSHA 29 CFR 1926.850. With two employees, Colorado workers' compensation is not optional: CDLE states that employers with one or more Colorado employees must maintain coverage and imposes additional construction-industry compliance around direct contractors. Colorado workers' compensation requirements.
Local variation and address checks
Denver example
The local demolition permit sequence requires state asbestos approval before the city demolition application and utility cut-offs before permit issuance. The city also publishes demolition-specific liability thresholds and XCU coverage language. This is a local example, not a statewide rule.
Local authority examplePikes Peak region example
The regional building authority states that contractors must be licensed before consulting for, contracting for or performing permit-required work, and a passing exam can be required. Confirm the license class that covers the exact demolition scope.
Local authority exampleWestern-slope / county example
Some municipalities route contractor licensing and building permits through the county while keeping planning, right-of-way or tax clearances at the city. The final operating address and each project address must be checked separately before quoting a fixed permit allowance.
Address verification requiredOfficial local examples: Denver demolition permits and Pikes Peak Regional Building Department licensing. The statewide 8 – 14 week launch estimate assumes these address checks, equipment procurement and staffing overlap; a difficult zoning case, historic review, asbestos abatement or utility delay can extend the first job well beyond that range.
Operating economics
How one demolition crew can produce $71k a month statewide
Demolition projects vary too much for a single “average job” to be reliable, so this model uses a productive crew-day as the natural revenue unit. A crew-day is a day when the owner-operator, two laborers and core equipment are earning project revenue, not estimating, moving between sites, waiting on utilities or repairing equipment. The Base case assumes 20 nominal workdays, a practical ceiling of about 16 productive days after sales/admin/maintenance/weather friction, and 11.5 productive days – 72% of that practical ceiling.
Base net revenue = 11.5 productive crew-days × $6,200 net earned revenue per crew-day = $71,300/month.
The $6,200 is a modeled planning rate, not a published Colorado price quote. It represents a mix of small structural/light-commercial demolition, selective/interior gut-outs and concrete/slab removal after customer credits, excluding sales tax collected and pass-through hazardous-material abatement. Bid each project from quantity takeoff, disposal class/tons, mobilization, crew/equipment days and risk – not from this rate alone.
| Metric | Downside | Base | Upside |
|---|---|---|---|
| Productive crew-days / month | 8.0 | 11.5 | 14.5 |
| Net earned revenue / crew-day | $5,700 | $6,200 | $6,500 |
| Monthly net operating revenue | $45,600 | $71,300 | $94,250 |
| Annualized stabilized revenue | $547,200 | $855,600 | $1,131,000 |
| Passive-basis normalized cash operating profit | – $390 | $15,503 | $29,198 |
| Working-owner pre-tax business cash benefit | $5,950 | $23,330 | $38,300 |
| Working-owner cash after modeled debt + maintenance capex reserve | $59 | $17,439 | $32,409 |
Monthly net revenue – Colorado statewide model, Typical scope, 2026 USD
Taxability convention. Colorado DOR states that services generally are not subject to sales tax, while tangible personal property generally is. The Base case therefore treats core demolition service revenue as service revenue and excludes collected transaction tax from revenue. Separately sold salvage/materials or any contract structure that creates taxable retail sales must be checked before invoicing, including home-rule local requirements. Colorado DOR sales-tax license guidance.
Cash timing is different from earned revenue. The model assumes invoices are earned as work progresses, with an average receivable cycle near 25 days and ordinary supplier/hauler terms partially offsetting that receivable. Customer mobilization deposits, if collected, are treated as deferred/customer-deposit liabilities until the related work is earned; they improve cash timing but are not counted as revenue twice.
Cost structure
What does a Colorado demolition crew cost each month?
At Base production, non-owner variable cost is $2,080 per productive crew-day: about $825 disposal/recycling, $550 subcontracted hauling/mobilization, $450 fuel and $255 consumables/PPE. Colorado's published disposal prices vary sharply by location and material. A three-jurisdiction 2026 public landfill basket shows general/mixed C&D rates of roughly $56.66, $65 and $71.31 per ton, a median of $65/ton; the Base $825 daily disposal allowance layers modeled hauling/container cost on top of gate fees. Exact waste composition and distance can move this line dramatically.
Fuel is also location-sensitive. The U.S. Energy Information Administration reported Rocky Mountain No. 2 diesel at $5.537 per gallon for August 24, 2026. The model rounds to a roughly $5.50 planning basis and assumes fuel use across excavator, loader, pickup and mobilization support. EIA Rocky Mountain diesel series.
| Cost line | Monthly amount |
|---|---|
| Disposal and recycling gate/container cost | $9,488 |
| Subcontracted trucking and equipment mobilization | $6,325 |
| Fuel | $5,175 |
| Consumables, PPE and small job supplies | $2,933 |
| Two laborers – wages + modeled payroll burden | $10,500 |
| Yard occupancy | $2,400 |
| Insurance | $3,800 |
| Repairs and routine maintenance | $2,300 |
| Marketing, admin, utilities, professional fees and recurring licenses | $5,050 |
| Non-owner cash operating cost before debt and maintenance capex reserve | $47,970 |
Labor is modeled above the legal floor. Colorado's 2026 minimum wage is $15.16/hour, but demolition cannot be staffed credibly at minimum wage. BLS/O*NET 2025 data put Colorado construction laborers around the low-$20s per hour; the model pays two laborers at about $25/hour and adds payroll/insurance burden to reach roughly $10,500 per month. A current BLS metro release also shows construction laborers at $23.66/hour and operating engineers at $29.14/hour in one Colorado market, supporting the choice to value skilled operator labor above a basic laborer. BLS May 2025 construction wage release.
Yard basket. Three current Colorado contractor/storage-yard observations were normalized to monthly rent per acre: about $2,516/acre for a 3.18-acre fenced industrial yard, $3,500 – $4,000/acre for a 2026 contractor-storage listing, and $6,000/acre for a smaller storage-yard offering. The midpoint/median planning level is about $3,750/acre/month. For a half-acre founder yard, the model uses $1,875 of land rent plus about $525 for a small office/container, security and utilities, or $2,400/month. Small parcels do not always price linearly; local quote required. Colorado contractor-yard observation.
Three lines can break the Base case
Disposal: contaminated or unsorted loads can reset the bid economics. Insurance: demolition/XCU and workers' comp pricing is quote-driven and can be far above a generic contractor package. Utilization: one permit delay that removes two productive days costs roughly $12,400 of modeled revenue before considering remobilization.
Debt principal, interest, maintenance capex, income tax and changes in working capital are not hidden inside the operating-cost total. The modeled $3,891 monthly equipment payment is below operating profit; a separate $2,000/month maintenance-capex reserve is also below operating profit. No owner income-tax reserve is modeled, so every owner-cash figure is pre-tax and is not personal tax advice.
Unit economics
What does one productive crew-day contribute?
The economic view must charge the owner's labor even though the owner may not run payroll for themselves. In the Base case, direct owner-operator replacement labor is valued at $425 per productive crew-day: 10 job hours at a modeled $34/hour market wage plus about 25% employer burden. The fixed estimator/project-manager portion is valued separately at $2,940/month and is not put into unit contribution. This prevents the same owner labor from appearing twice.
| Metric | Per crew-day / month | Rate / volume |
|---|---|---|
| Net earned revenue | $6,200 | 100.0% |
| Variable non-owner cost | $2,080 | 33.5% |
| Cash contribution before owner compensation | $4,120 | 66.5% |
| Variable owner-operator replacement labor | $425 | 6.9% |
| Passive/economic contribution | $3,695 | 59.6% |
| Cash-survival break-even | $36,192/mo | 5.84 days |
| Sustainable working-owner break-even with $10,000 target owner compensation | $51,240/mo | 8.26 days |
| Passive-owner break-even | $45,288/mo | 7.30 days |
| Passive debt-service cash break-even incl. maintenance capex reserve | $55,172/mo | 8.90 days |
Owner-income bridge. Base passive-basis normalized cash operating profit is $15,503/month. Add back only the owner labor that a working owner actually supplies – $4,888 of variable operator replacement labor plus $2,940 of fixed management/estimating replacement labor – and working-owner pre-tax business cash benefit becomes $23,330/month. That total is not “salary.” Roughly $7,828 is the imputed market value of work performed; the remaining $15,503 is residual normalized operating return before D&A, debt, maintenance capex and taxes.
Survival and returns
Where is break-even and when does founder equity come back?
Break-even changes depending on whose labor and financing burden is being tested. The cash-survival case excludes imputed owner compensation and needs only about 5.84 productive crew-days per month. A sustainable working-owner case that targets $10,000/month of pre-tax owner compensation needs about 8.26 days. A passive owner who hires market replacements for both direct operation and management needs 7.30 days. After adding the modeled equipment payment and $2,000 monthly maintenance-capex reserve to the passive basis, the debt-service cash threshold is 8.90 days.
Crew-day capacity test – Colorado statewide Base model, 16-day practical ceiling
Runway. The Base ramp assumes 5.0 productive days in month 1, 6.5 in month 2, 8.0 in month 3, 9.5 in month 4, 10.5 in month 5, 11.0 in month 6 and 11.5 from month 7. On a passive-normalized cash basis after debt service and the maintenance-capex reserve, months 1 – 3 consume approximately $14,406, $8,863 and $3,321. The $70,000 opening reserve bottoms near $43,400, staying above the $40,000 minimum floor, and rebuilds to roughly $70,000 around month 8. If permits delay the ramp by a full month, the reserve should be resized before launch rather than assuming the same runway.
Primary payback. Levered founder-equity payback is calculated on passive-normalized equity cash flow so the founder's labor is not disguised as capital return. Starting with the – $290,750 founder contribution at month 0, the model withholds distributions while the reserve rebuilds. Month 8 can distribute only the amount above the $70,000 reserve target; thereafter stabilized passive cash after debt and maintenance capex is about $9,612/month. Cumulative founder equity first reaches zero in approximately month 38, pre-tax. Downside performance would not support normal equity distributions; the Upside case would shorten payback materially, but is not used as the planning answer.
Market context
Colorado demand is real, but demolition TAM is not cleanly published
A responsible statewide demolition-market dollar figure is not publicly determinable from the available category data. The closest standard industry classification, NAICS 238910 Site Preparation Contractors, combines demolition with excavating, grading, septic-system work and related site preparation. Treating all 238910 receipts as demolition would overstate the market, while multiplying a national demolition estimate by Colorado's population share would create false precision.
6.0 million residents
Census estimated Colorado at about 6.01 million people on July 1, 2025, up 4.1% from the 2020 estimates base. Population is a demand proxy, not demolition revenue.
Reported government data33,754 permits in 2025
Census QuickFacts reports 33,754 building permits for 2025. New construction does not directly equal demolition, but redevelopment and replacement activity can create demolition opportunities.

Sensitivity: watch crew-days before chasing price
The earliest useful KPI is productive crew-days sold and completed, followed by net earned revenue per crew-day, disposal cost per crew-day, mobilization cost, equipment downtime and receivable days. At the Base $6,200 rate, losing two productive days removes about $12,400 of revenue. A $500/day increase in disposal/hauling on 11.5 days costs $5,750/month. By comparison, a 5% price increase on Base volume adds only about $3,565/month before any demand response. That is why permit reliability, waste characterization and equipment uptime deserve more attention than headline price.
Permit delay
Financial line: productive crew-days and revenue. Early warning: days from signed contract to permit-ready mobilization; jobs waiting on asbestos or utilities.
Waste-cost surprise
Financial line: disposal/recycling and hauling. Early warning: estimated vs actual tons, contamination/rejection events, landfill mix and haul miles.
Equipment downtime
Financial line: repairs plus lost crew-days. Early warning: scheduled-service compliance, hydraulic/undercarriage condition, downtime hours and emergency rental spend.
