How to Hire and Manage Residential Contractors

Randall A. Cantrell

Quick Facts

  • A home typically is purchased after passing an inspection conducted by a trained professional (Ruppert, Fentriss, & Lee, 2008).
  • Passing a home inspection shows the home complies with minimum building-code standards and is safe for occupancy (International Code Council, 2019).
  • As of 2019, more than 400,000 single-family, multifamily, and affordable housing units were certified by the US Green Building Council's LEED for Homes program and more than 216,000 dwelling units by the Home Innovation Research Labs' National Green Building Standard (U.S. Green Building Council, 2019; Home Innovation Research Labs, 2023).
  • The Florida Green Building Coalition has certified more than 30,000 projects in Florida (Florida Green Building Coalition, 2023).

Why You Should Select a Contractor Carefully

The following story explains why it can be important to choose a contractor carefully and to understand what you should look for when hiring one. The rest of this publication describes what you need to know about hiring a residential contractor, such as understanding the contract process, finding a contractor, determining a payment schedule, knowing the differences between types of contractors, and preparing questions to ask before hiring a contractor. 

A homeowner decided to add a sunroom and contacted with the contractor who originally built the home. After agreeing on the final design and price, they entered into a contract. Although the contract was an "as-built" contract, the builder was delayed in completing the addition. However, the contract did not include a penalty clause for work not completed on time. The builder became ill, and the project was delayed indefinitely. However, enough work was completed for the sunroom to pass final inspection for occupancy, but some exterior details had not been completed according to the agreement. The parties agreed the homeowner would pay 50% of the total cost when the job began and 50% when the job was completed.

After the builder regained health and verified the sunroom passed the final inspection, the contractor billed the homeowner for the remaining unpaid balance. The homeowner did not pay the full amount and instead subtracted the amount quoted by another contractor to complete the remaining exterior details. However, the contractor insisted the job was complete upon passing the final inspection and sent overdue bills (including interest) to the homeowner. The homeowner contacted an attorney who helped draft a cease-and-desist order to resolve the matter. The homeowner did not hear from the contractor again, but the remaining work was not actually contracted and completed until years later when the home was listed for sale. The cost to prepare the home for sale was ultimately increased by a cost of about $1,000 because of the uncompleted work.

Why You Should Understand the Contractor Price-Quote Process

When hiring a contractor, ensure the contractor is licensed in the state to do business and is bonded. The contractor should also possess workers' compensation insurance and provide a precise scope of services for the price quote being offered. Using a properly licensed contractor is not a guarantee of a successful project, but it provides the residential owner with alternative should problems arise. Before you sign a contract, check the contractor's current active status as a licensed contractor. You can do this by obtaining the contractor's individual license number and verifying it with the Florida Department of Business and Professional Regulation (DPBR). Visit the DBPR's website ( and click on "Verify a License" or call its customer contact center (850-487-1395).

Residential contractors are only permitted to provide services corresponding to the license(s) they possess in Florida but may provide multiple services in the areas where they are licensed. Subcontractors employed by a contractor typically are the contractor's responsibility, and evidence of their work-related documents should be on file before starting any work with the contractor (for more information, see

Contractors use many types of contracts, and most of them are written to protect the contractor, not the homeowner. Before you sign any contract, carefully read it and address any questions to the contractor. Also, add any clarifications to the contract to avoid misunderstandings.

Typically, a homeowner should solicit price quotes from three different contractors to see which offers the best value. Be careful not to misinterpret value as just the lowest price. One contractor may offer a different scope of services for accomplishing the job. Make sure you understand the fine details to determine if the price quotes are for the exact same amount of labor and type of materials or if one contractor offers differences from other contractors. Also, any project that does not secure building permits from the local building permit office automatically puts the homeowner at risk. This is important because homes need to be inspected before they are listed for sale. If a home inspector determines that any part of the home does not meet the minimum standards required by the international building code (or local building code), then the home must be brought up to code at a complete cost to the homeowner before it can be sold.

Finding a Contractor and Determining Contractor Financial Stability

A contractor usually has completed multiple jobs within driving distance of your home. As a potential client, you can request a list of those jobs and contacts. You may not be permitted to visit these contacts' homes (due to privacy-related issues), but often these contacts will at least talk to you on the phone to discuss the contractor's work. Some contractors offer referral payments to homeowners who allow potential clients to visit their home, but usually only if the visitors hire the contractor to do the pending job. Further, a credible contractor should be willing to certify revenues in reserve and/or offer business loan arrangements to cover the cost of any anticipated work agreed on in the scope of services.

Determining Compensation, Payment Schedule, Breach, and Warranty in a Contract

When negotiating a contract, you must agree on specific details in writing regarding payment. These details should include how much will be paid in advance (to buy materials, etc.), how much will be paid in "draws" (periodic payments during the actual construction process), and how much will be paid upon completion. The "draws" or amounts paid to the contractor should be closely related to the percentage of work completed at the date of payment. This can be accomplished by a payment schedule in the contract based on stages of completion (such as concrete slab poured/placed, roof dry-in, etc.) or based on a percentage of completion for each set period (such as biweekly or monthly). Also, a substantial final payment, payable only after the certificate of occupancy (if applicable) has been issued and all corrective work has been completed, can encourage the contractor to complete the project to the owner's satisfaction. Both parties should agree on a clear definition of what constitutes "completion" of the job.

Any change orders that occur during the construction process should be handled separately from the original contract. All inspection requests must be the contractor's responsibility, and ensure the contract specifically includes what constitutes contract breach (e.g., how many times the contractor can fail inspection before being terminated). Further, once the contractor has completed the job, a warranty must be in place that outlines how "callbacks" are handled and in what period of time they are honored. This must include materials and labor costs incurred after the job is complete.

Construction Liens

Be aware that under Florida law individuals who provide labor or materials to make improvements to your property, such as for the construction or remodeling of a home, are granted "lien" rights for unpaid items. The law concerning construction liens is found in Title XL, Chapter 713 of the Florida Statutes. These lien rights are not limited to your contractor and extend to most subcontractors, material suppliers, and laborers, even if you (as the owner) have not contracted directly with them (these are called "non-privity" lienors). As a result, you may be liable to pay for labor or materials, even though you already paid your contractor for the same work. In other words, you may end up paying twice for the same thing! There are a number of documents vital to the operation of the lien law. The forms specified for this law include the following: Notice of Commencement, Notice to Owner, and Claim of Lien (for more information, see:,%20Notice%20to%20Owner,%20and%20Claim%20of%20Lien).

Questions to Ask Contractors

The following list provides some basic questions a homeowner should ask before hiring a contractor:

  • What is the average time your company takes to respond to a client after receiving a call?
  • What is the average turnaround time for a verbal, written, or in-person estimated scope of work and budget once your company has contacted with a potential client?
  • Do you train your staff to provide high-quality customer service? If so, please provide any helpful documents explaining your company's customer service policy related to your mission, goals, objectives, and/or principles.

Information Contractors Should Provide to Homeowners

The following list includes information homeowners can ask a contractor regarding any persons working for them who will enter onto the homeowner's property, including employees or subcontractors. You have the right to know the following information about employees and subcontractors.

  • Name
  • Title
  • Qualifications
  • Experience
  • Years of service with current company
  • Years of experience in relevant industry/trade
  • Relevant professional certifications

Understanding Differences Between Types of Builders

The residential construction sector has innovative builders who erect homes according to nationally recognized green standards (Cantrell, 2021). In doing so, they attempt to increase home occupants' awareness and desire for new building products and materials (Koebel et al., 2003). Homebuyers need to understand what it means to buy a home certified by a green building program (GBP). Some builders understand better than others the benefits associated with building to such standards. Alternatively, some builders may try to convince homeowners that they are building to green standards without the need for certification through a GBP. In these cases, the builder may try to sell what sounds like a green construction project when in reality it is not truly a "green" construction project. If a contractor attempts to sell you a "green" job without certifying it through a GBP, then request that each green item be discussed while referring to a GBP manual. This will assist you in understanding how closely the contractor aligns each work item to actual GPB criteria.


If you are looking for a contractor for either home building or remodeling, ask difficult questions before you enter into a contract. This way you and the contractor have a clear understanding of the other's expectations. Before signing a contract and beginning a project, is the best time to thank contractors for their consideration and time as you part ways, rather than risking entering into an unfortunate working relationship that could require legal intervention. Contractors understand potential clients, and they will inform you if they do not want to accept a contract with you. This negotiation period should not be taken personally by either party and should only develop into a business relationship that exists during the period of hire and warranty outlined in the contract.
