A rentable-fleet model keeps opening cash below the cost of owning iron
Plan on about $243,000 to open a founder-scale demolition company in New Hampshire, with a credible $124,000 Lean to $480,000 Premium range. The statewide Base case is an independent LLC with one owner-operator/estimator, two field employees, one owned one-ton dump truck and equipment trailer, rented excavators and loaders, and a six-job monthly practical ceiling. At 5.25 completed jobs and $84,000 of net monthly revenue, the model produces $18,500 of normalized passive-owner cash operating profit before D&A, or $28,100 of working-owner pre-tax business cash benefit before debt service, maintenance capital, taxes, and reserve top-ups. The biggest uncertainty is job mix: a single asbestos finding, long haul, structural complication, or contaminated load can erase the contribution from an otherwise profitable project.
Configuration fingerprint. Independent, owner-operated New Hampshire LLC; one mobile crew; one owned dump truck and trailer; heavy equipment rented by project; six-job monthly practical capacity; core mix of interior selective demolition, small residential/light-commercial structure removal, concrete/site removals, and debris hauling. Hazardous-material abatement and blasting are excluded and subcontracted to properly licensed specialists. This fingerprint is the comparable case for other states.
Capital plan
The reserve – not the truck – is the line most founders underfund
The Typical scope assumes used commercial vehicles and tools, rented heavy iron, and no permanent yard purchase. It separates opening supplies from net working capital and unrestricted operating cash. Initial net working capital is receivables plus prepaids less payables; the separately listed opening supplies are not counted again. The reserve covers the modeled ramp and keeps a $25,000 minimum cash floor.
| Use of funds | Lean | Typical | Premium |
|---|---|---|---|
| Truck, trailer and vehicle setup | $28,000 | $62,000 | $105,000 |
| Tools, attachments, PPE and dust control | $18,000 | $38,000 | $70,000 |
| Heavy equipment / yard setup | $4,000 | $12,000 | $110,000 |
| Non-refundable filings, permits and professional setup | $3,500 | $7,500 | $14,000 |
| Insurance deposits, bonding setup and refundable deposits | $9,000 | $19,000 | $35,000 |
| Pre-opening payroll, training and launch marketing | $8,500 | $18,000 | $31,000 |
| Opening supplies and consumables | $5,000 | $8,000 | $13,000 |
| Initial net working capital | $14,000 | $28,000 | $46,000 |
| Opening operating-cash reserve | $27,000 | $42,000 | $68,000 |
| Contingency | $7,000 | $8,500 | $8,000 |
| Total project cost | $124,000 | $243,000 | $500,000 |
The displayed Premium total is $500,000; the decision range uses $480,000 as a practical target after an assumed $20,000 documented equipment-financing commitment. No external funding is subtracted from Lean or Typical. Thus Typical founder cash required and peak interim cash are both $243,000. A surety bond face value is not treated as a cash expense; only a quoted premium or actual collateral belongs in the capital plan.
Critical path
Asbestos notice and municipal sign-off govern the opening calendar
The LLC can be formed quickly, but legal operation is job- and address-dependent. New Hampshire's asbestos management program requires an asbestos demolition notification to be received at least 10 working days before demolition. Federal OSHA also requires a written engineering survey before employees begin, and utility lines must be shut off, capped, or controlled outside the building line under 29 CFR 1926.850.
Form and insure
File LLC, EIN and tax/employer accounts; bind general liability, commercial auto and workers' compensation.
Source fleet
Inspect and acquire the truck, trailer, tools, PPE and dust controls while rental accounts are opened.
Build controls
Written safety program, competent-person assignments, estimating templates, waste profiles and subcontractor verification.
Win and clear work
Secure contract, survey hazards, arrange utilities, inspect for asbestos and file notices and local permits.
Mobilize
Complete pre-job plan, site protection, hauling/disposal bookings, customer deposit and final permit release.
| Requirement | Level / status | Fee or timing | Dependency | Authority / source |
|---|---|---|---|---|
| LLC certificate and annual report | State / mandatory | $100 formation; $100 annual report; online handling may add $2 | Before contracts and bank account | NH Secretary of State |
| Asbestos inspection and demolition notice | State / mandatory for demolition; abatement conditional | Notice received at least 10 working days before work; fee confirm on current form | Inspection before notice; licensed abatement when applicable | NHDES |
| Written engineering survey and utility controls | Federal / mandatory | Before employee entry; professional quote required | Structure and adjacent exposures assessed | OSHA Subpart T |
| Workers' compensation | State / mandatory with any employee | Carrier quote required; bind before first hire | Payroll and class codes | NH Department of Labor |
| Lead abatement license | State / conditional | Current application and fee required if offering abatement | Licensed contractor and certified workers | RSA 130-A:12 |
| Demolition / building permit | City or town / varies | Varies by city/county; not a statewide fee | Address, utilities, historic review and site plan | Final local building authority |
Local variation and address checks. A compact three-market sample illustrates why one city cannot stand in for the state: Manchester requires a utility-signed demolition sign-off before permit issuance; Concord notes that certain demolition reviews may take up to 60 days; and Portsmouth routes building and land-use permits through its Inspection Office. Confirm demolition, historic-district, traffic, right-of-way, dust, noise, fire, sewer/septic, erosion-control and certificate-of-occupancy consequences at the exact address before committing equipment or a start date.
Operating economics
Five mixed jobs a month can support one crew – if estimates isolate disposal risk
Net operating revenue excludes customer tax collections and pass-through permit reimbursements. New Hampshire has no general sales tax, but taxability and customer billing should still be reviewed for mixed contracts and out-of-state work. The model earns revenue when demolition service is performed; customer deposits remain a contract liability until earned. Base revenue is 5.25 jobs × a weighted $16,000 net contract value. Capacity is six monthly jobs because mobilization, utility clearance, sorting, hauling, equipment availability and weather – not labor hours alone – constrain throughput.
| Driver / result | Downside | Base | Upside |
|---|---|---|---|
| Completed jobs / month | 4.0 | 5.25 | 6.0 |
| Average net contract | $14,500 | $16,000 | $18,000 |
| Monthly / annual revenue | $58k / $696k | $84k / $1.008m | $108k / $1.296m |
| Passive contribution margin | 43% | 45% | 46% |
| Fixed costs incl. fixed owner replacement | $19,300 | $19,300 | $25,000 |
| Normalized passive-owner profit | $5,640 | $18,500 | $24,680 |
| Owner replacement labor avoided | $8,000 | $9,600 | $11,500 |
| Working-owner pre-tax business cash benefit | $13,640 | $28,100 | $36,180 |
| Potential working-owner cash after debt, maintenance capex and NWC top-up | $7,190 | $21,650 | $28,130 |
The Upside case is capped at six jobs and adds a $5,700 monthly coordinator/field-lead tier inside fixed cost; it does not pretend the same crew can exceed physical capacity. Downside retains minimum insurance, vehicle, office and owner-management costs. All profit figures are before income tax. New Hampshire's business tax guidance lists a 7.5% Business Profits Tax and 0.55% Business Enterprise Tax, with 2025-start filing thresholds of $109,000 and $298,000 respectively; actual taxable bases and credits require professional advice.
Unit economics
A $16,000 job leaves $7,200 after replacing the owner's field labor
The natural unit is one completed demolition job. Base direct labor uses two paid crew members plus the owner's direct operating time, all on a fully loaded basis. The owner's fixed estimating, sales and supervision replacement value stays in fixed cost and is not charged again to the unit.
| Bridge | Per job |
|---|---|
| Net contract revenue | $16,000 |
| Disposal and tipping (14%) | ($2,240) |
| Rented equipment, fuel and hauling (11%) | ($1,760) |
| Fully loaded non-owner direct labor (20%) | ($3,200) |
| Variable owner-replacement field labor (5%) | ($800) |
| Subcontract, supplies and processing (5%) | ($800) |
| Passive/economic contribution (45%) | $7,200 |
The estimating rule that protects the margin
Quoted price = direct job cost ÷ (1 – target contribution margin).
Example: a project with $8,800 of expected direct economic cost needs a $16,000 price to produce a 45% passive contribution margin.
Every waste profile should state assumed tons, material class, haul distance, facility, equipment days, crew hours, salvage credit and hazardous-material exclusion.
Disposal is especially local. NHDES says burning construction and demolition debris is illegal; approved handling and disposal are required. Published 2025 municipal observations range from $150 per ton for commercial C&D in Merrimack to $275 per ton in Lebanon, with different access rules and material exclusions. These are not a statewide average; the model uses disposal as 14% of revenue and requires a facility-specific quote for every bid.
Owner economics
Owner labor is worth $9,600 a month before capital earns a dollar
“Owner income” has two parts: market compensation for work performed and residual return on the invested capital. The Base model imputes $4,200 of variable field labor and $5,400 of fixed estimating, sales, compliance and supervision labor. That $9,600 is not an owner draw; it is the loaded cost the business would incur to replace the owner. New Hampshire requires workers' compensation for any full- or part-time employee, and the wage floor remains the federal $7.25, but skilled demolition labor must be budgeted at market rates rather than the legal minimum. The model uses $16,800 monthly for two non-owner employees including payroll burden and workers' compensation planning allowances; carrier quotes control.
Passive-owner return
$18,500 normalized cash operating profit before D&A. After modeled debt service of $3,250, maintenance capex of $2,200 and $1,000 NWC top-up, $12,050 remains before income tax.
Working-owner benefit
$18,500 residual profit + $9,600 replacement labor avoided = $28,100 pre-tax business cash benefit. After the same below-line cash items, potential cash is $21,650.
Accounting limit
Depreciation is not fabricated because useful lives and tax basis depend on the final fleet. Therefore the article reports cash operating profit before D&A, not EBIT or accounting net income.
The illustrative debt line assumes $125,000 financed, 15% cash down embedded in the Typical project funding, 9.0% APR, 48 months and about $3,110 monthly principal-and-interest plus $140 in fees/other scheduled financing cash. Replace it with an executed term sheet. Income-tax reserves are excluded; a distribution is never guaranteed take-home pay.
Thresholds and liquidity
Three jobs cover the passive model; four are safer
Break-even must match the ownership basis. Within the one-crew capacity band, the cash-survival contribution margin before variable owner labor is 50%; the passive/economic margin after variable owner replacement labor is 45%. Fixed non-owner overhead is $13,900 monthly, while fixed owner-management replacement is $5,400.
| Measure | Numerator / margin | Result | Decision use |
|---|---|---|---|
| Cash-survival break-even | $13,900 / 50% | $27,800; 1.74 jobs | Covers non-owner cash overhead before owner pay |
| Sustainable working-owner break-even | $23,500 / 50% | $47,000; 2.94 jobs | Adds $9,600 target owner compensation |
| Passive-owner break-even | $19,300 / 45% | $42,900; 2.68 jobs | Replaces both field and management owner labor once |
| Debt-service cash break-even, working basis | $27,250 / 50% | $54,500; 3.41 jobs | Adds debt service and maintenance capex |
| Opening reserve runway | $42,000 reserve; $25,000 floor | 6-month ramp funded | Monthly schedule bottoms at $26,800 in month 3 |
| Unlevered project payback | $243,000 month-0 project capital | Month 14 – 16 | Pre-financing, pre-tax monthly cumulative project cash |
The modeled monthly revenue ramp is $28,000, $42,000, $52,000, $65,000, $74,000 and $84,000 in months 1 – 6. Customer receipts lag earned revenue by roughly 15 days; accounts receivable is reflected in initial NWC. The reserve is capitalized once at month 0, so ramp losses are not counted a second time. Base unlevered cumulative cash recovers $243,000 during months 14 – 16, depending on exact collections and maintenance timing. Downside does not reach project payback inside 36 months; Upside reaches it around month 11. Levered founder-equity payback is not stated because final draw dates, fees and collateral are unknown.
State market and controls
New Hampshire demand is visible, but demolition-only market revenue is not
A reliable demolition-only state-market amount is not publicly determinable from available category data. The closest official category, NAICS 238910 Site Preparation Contractors, combines demolition with excavation, grading, septic work, land clearing and equipment-with-operator services. Establishments and employment in that category are useful supply proxies, not demolition revenue. A founder should validate demand through awarded permits, contractor bid lists, property redevelopment, public procurement and a 45 – 60 minute haul radius around the eventual yard.
Tons per job
Early warning: actual tons ÷ estimated tons. A 10% overrun should trigger estimate review by material type and disposal facility.
Equipment days
Early warning: billed rental days ÷ estimated days. Standby from utility or permit delays should be contractually assigned.
Crew-hours variance
Early warning: loaded field labor ÷ job revenue. The Base ceiling is 25%, including variable owner replacement labor.
Backlog quality
Early warning: permitted, deposit-paid revenue rather than unsigned proposals. Target at least six weeks of cleared work.
Receivable days
Early warning: completed but uncollected billing. Past 30 days, the $28,000 NWC allowance tightens quickly.
Incident-free hours
Early warning: near misses, property damage and citations. Safety failure affects insurance, labor availability and bidding access simultaneously.
The state's low statutory minimum wage does not make demolition labor cheap; risk class, skill, seasonality and nearby New England labor markets matter more. Insurance and workers' compensation can therefore move margin faster than general inflation. Likewise, no general sales tax simplifies customer invoices, but the Business Enterprise Tax makes compensation and interest relevant even when accounting profit is modest. These are New Hampshire-specific effects that should be modeled line by line, not through a blanket state multiplier.
Sources and method
What is official, what is derived, and what still needs a quote
The price basis is 2026 USD. Official rules and fees are stated as published; job prices, equipment, insurance, payroll burden, startup allowances and operating performance are modeled planning assumptions, not reported statewide averages. The statewide planning basket uses three local authorities only to show permit variation and two published municipal disposal points only to bracket possible tipping exposure. No local example defines the Base case.

High confidence entity fees, tax rates, asbestos notice timing, OSHA duties and workers' compensation trigger. Moderate confidence disposal sensitivity and launch sequence. Model-dependent contract values, job mix, equipment cost, insurance, wage burden, margin, ramp and payback. The largest uncertainty is the interaction of structure condition, hazardous materials, debris tons and haul/disposal access. Confirm the final address, contract scope, waste facility, insurance classifications, asbestos survey, utilities and permits before committing capital. This is planning analysis, not legal, tax, engineering or safety advice.
