How to Avoid Contractor Scams in Kansas City: Deposits, Permits & Warning Signs

Some contracts ask for 25% of the price at signing & another 25% on the first day of work. Under that schedule, a homeowner can pay half the contract before much has been built, & if the contractor stops showing up, all of that money is at risk. A schedule like this is not proof of a scam. It is a good reason to ask what each payment covers before signing anything. The questions below draw on 32+ years of combined experience pricing & building projects across the Kansas City metro.

Know what each payment covers

Each payment in a contract should match something concrete: a material order, a phase of work or work already finished. These questions make a payment schedule easy to read:

  • What is due at signing, at the start of work, during construction & at completion?
  • What does each payment cover?
  • If a payment is for a material order, what document will show that order?
  • How do the payments track the work completed & the costs incurred?

It is also fair to ask how the contractor will pay for materials & the first phase of work. An established firm usually has working capital & charge accounts with its suppliers, so it does not need a large advance to get started. Supplier credit does not make a contractor honest, & a deposit alone is not a sign of fraud. The answer simply shows how much of the risk the homeowner is carrying.

All Under One Roof bills for work after it is done, using material receipts & labor hours, instead of collecting a large share of the contract up front.

Know who is responsible for the permit

A contractor who asks the homeowner to pull the permit is one of the clearest warning signs. In a typical case, the homeowner takes out the permit for a room addition, & the contractor doing the work is never named on it. If that contractor walks away, the homeowner is left with an unfinished addition & an open permit that still has to pass inspection & be closed out.

The Kansas Attorney General's consumer guidance recommends checking with the local building inspection department, & it warns that a contractor who asks the homeowner to get the permit may be unlicensed. That said, a permit in the owner's name is not always a problem. Some cities let owners act as their own general contractor. The City of Olathe's building permit guide, for example, allows it for an occupied primary single family residence. What matters is who is responsible for the work:

  • Which city or county has jurisdiction over the property?
  • Who will apply for the permit, & who will be listed as the contractor?
  • If the homeowner is asked to apply, what is the reason, & does the building department allow it for this project?
  • Who will schedule the inspections & see the permit through to final approval?

Closing out the permit is part of the job. For projects under Johnson County's own jurisdiction, the county's building permit guidance makes the general contractor responsible for finalizing & closing out the permit unless the homeowner did the work. Projects inside city limits follow that city's process instead. The county also offers a licensed contractor search, but a county license does not answer what every city requires. The building department for the city or county where the house sits, in Kansas or Missouri, has the final word.

Compare the scope as well as the price

Two bids with the same total can cover very different work. A detail left out of the original scope often comes back halfway through construction as an extra, & work may stop while the change is priced & approved. The better comparison is what each proposal includes & what it leaves out:

  • What is included, & what is excluded?
  • Which allowances are built into the price, & what happens if a selection costs more?
  • How is extra work priced, documented & approved before it starts?
  • Is there a fee for writing a change order, & how much is it?

Not every change order is a red flag. Some changes are choices the homeowner makes along the way, & some come from conditions no one could see until a wall was opened. The protection is a contract that explains, before work starts, how changes will be handled. A fixed price is not a warning sign by itself, & a cost plus contract is not automatically the cheaper option.

Know how costs will be documented

All Under One Roof prefers cost plus billing. Monthly statements are issued after the work is done, & each one is built from actual material receipts & labor hours, backed by daily job records. In any cost plus contract, two definitions matter most: which costs are billable, & how the contractor's fee is calculated. Whatever the billing method, both sides should agree before signing on what records will be provided & when:

  • Which costs are billable, & which are covered by the contractor's fee?
  • What are the labor rates, & how are hours tracked?
  • What receipts or records support each statement, & when are statements issued?

Ask about materials & how they will be installed

A good proposal names more than a product & a price. The material has to suit how & where it will be used, & how long it lasts often depends on installation details, such as flashing & protection, that never show in a finished photo. Three questions cover most of it:

  • Which material is proposed, & why does it suit this project?
  • Which installation details matter most for it?
  • What warranty applies, & who stands behind it: the manufacturer, the contractor or both?

What a consultation should provide

A paid consultation should leave the homeowner better informed, whether or not that firm ends up building the project. All Under One Roof's consultations are meant to inform, not to pressure. A homeowner can pay for the consultation, take what was learned & hire a different contractor. Site visits, design work & detailed estimates are billed at $85 an hour under a consultation agreement, & photos, measurements or drawings supplied by the owner can be reviewed without a site visit.

Projects start with the Request Consultation form. The room additions, kitchen remodeling & whole home remodeling pages explain how each type of project is planned, drawn & permitted under one contract.

A short checklist before signing

  • A written scope listing what is included & what is excluded
  • A payment schedule tied to completed work or documented material orders
  • The contractor named on the permit, or a reason for the homeowner to apply that the building department has confirmed
  • An agreed process & fee for changes
  • An agreed billing method & the records behind it
  • The proposed materials, installation details & warranties in writing

Construction Consultation

A consultation request begins with a discussion of project scope, permitting, & timeline.
