Out-of-State Contractor, No Permit, and a Concealed Flue Condition
A Pennsylvania-based remodeling company holds a New Jersey HVACR contractor business license with a master qualifier who lives in New York and visits the jobsite about twice a month. A Monmouth County homeowner signed a one-page proposal for $14,800 to replace a furnace, coil, and condenser. The proposal shows no Home Improvement Contractor registration number, no start or completion date, and no cancellation notice. The company collected a 40 percent deposit of $5,920 and installed the equipment on a Saturday without pulling a permit.
While running the new 90% furnace's PVC flue, the crew found that the masonry chimney it intended to use has no liner and is shared with the natural-draft water heater. The contractor now wants $1,850 for a listed chimney liner plus $650 for permits and inspections. The homeowner refuses to pay and calls the municipal construction office. The contractor's direct cost for the original scope was $9,200; the liner adds $1,150 and the permit and inspection fees add $650.

Permits. Replacing a furnace and air conditioner is not ordinary maintenance in New Jersey; it requires a permit, plus an electrical permit for the new circuit, and the flue and chimney work may bring in the fire protection subcode. Confirm the exact subcode assignment with the local construction official. Only the licensed contractor or the property owner may apply, and the work must be inspected. Starting on a Saturday with no permit exposes the job to a stop-work order, penalties, and an inspection record the next contractor inherits.
Venting. A 90% condensing furnace cannot share a masonry chimney with an atmospheric water heater. The furnace must be vented per the manufacturer's instructions, and the water heater needs a properly sized, lined flue. This is both a code violation and a CO hazard, and it is the reason the scope cannot be completed as written.
Licensing. The business must hold the license, and the work must be performed by or under the supervision of the qualified master. A qualifier who visits twice a month from out of state raises a legitimate supervision question, and an unlicensed crew performing regulated work is a separate violation reportable to the Division of Consumer Affairs.
Contract. New Jersey home improvement rules require a written contract that identifies the contractor, carries the Home Improvement Contractor registration number, states start and completion dates, and includes the three-business-day cancellation notice for contracts signed at the home. This one-page proposal has none of it, and the deposit practices should be checked against the current limits.
2. Calculate the change order that actually protects the target margin, and explain how it should be presented. Assume the company requires a 38 percent gross margin.

Start with the economics of the original contract:
- Price $14,800, direct cost $9,200 → gross margin = (14,800 − 9,200) / 14,800 = 37.8 percent, essentially the 38 percent target.
- Cost ratio = 9,200 / 14,800 = 62.2 percent of price.
The corrected scope:
- New direct cost = 9,200 + 1,150 (liner) + 650 (permits and inspections) = $11,000.
- Price needed to hold a 38 percent margin = 11,000 / 0.622 = about $17,685.
- Change order = 17,685 − 14,800 = about $2,885.
The contractor's proposal of $1,850 + $650 = $2,500 recovers the added cost with zero margin and dilutes the job to (17,300 − 11,000) / 17,300 = 36.4 percent - you paid yourself nothing to manage a problem you should have found at the survey.
Presentation: a written change order, signed by the owner before the work proceeds, describing the concealed condition, the liner and permit line items, the schedule impact, and the owner's option to decline. Do not invoice permit fees as a surprise after the fact. The permit fees arguably belonged in the original price; the liner is a legitimate concealed-condition change. Say that out loud - it is what makes the change order defensible.
3. What should the company have done differently, and what should it do now? Address both the business process and the physical safety of the installation.
Read the worked answer
What should have been done:
- Confirm the business license, the qualifier's actual role, and the Home Improvement Contractor registration before advertising or contracting.
- Perform a site survey that includes the venting path. A masonry chimney with no liner shared with a water heater is exactly the condition to catch at the estimate, not mid-install.
- Put the permit and inspection costs in the base price and pull the permit before the crew mobilizes.
- Use a compliant written contract with the registration number, dates, and cancellation notice, and deposit within the current limits.
- Keep a qualified master on the job in a supervisory role that matches the scope.
What to do now:
- Leave the appliances in a safe condition. Neither the furnace nor the water heater may be left venting into an unlined shared chimney. If that means shutting down and tagging equipment, do it and document it in writing to the owner.
- Apply for the permits and schedule the inspections before any further work.
- Issue the written change order and give the owner the option to proceed or to have the original scope made safe and closed out.
- Photograph and document the concealed condition, the readings, and every conversation.
- Complete the manufacturer's commissioning and combustion testing and hand over the documentation.
- Review why the bid did not include a chimney inspection, and fix that step in the estimating process so the next job does not repeat it.
