Planning
Warranties, Permits, Financing and Exclusions: What to Check
“What can change the real cost after I sign?”

The short answer
Key takeaways
- Separate product and workmanship warranty terms.
- Confirm permits with the local building department.
- Compare total financing cost, not only monthly payments.
- Require written approval before extra work.
A warranty is only as useful as its written terms
Ask who provides the warranty, what is covered, the coverage period, exclusions and the claim process. Product coverage and installation workmanship may be provided by different businesses.
Check whether maintenance, registration, transfer or installation conditions affect coverage. Do not assume a marketing headline describes the complete warranty.
Confirm permit responsibility before work starts
Permit requirements depend on location and scope. Ask the local building department what applies and name the responsible party and fees in the contract.
The FTC flags contractors asking the homeowner to obtain required permits as a potential warning sign. Ask why, verify the rules independently and understand any owner-builder responsibilities before agreeing.
Compare financing away from the sales conversation
Ask for the cash price and written finance terms separately. Compare the annual percentage rate, fees, term, total payments and any promotional conditions with independent lenders. A lower monthly payment can still cost more overall.
The FTC advises shopping around rather than agreeing to financing through a contractor without comparison. Do not sign unread documents or transfer your deed without independent advice.
Write down exclusions and change-order rules
Ask what is not included: hidden-condition repairs, disposal, access equipment, finish restoration, permit fees or work by other trades. These are questions for your scope, not a claim that every project needs every item.
Agree who documents a changed condition, how added work is priced, how schedule changes are handled and who approves it before work continues. Keep signed copies.

Common questions
Quick answers homeowners ask next.
01Are permit fees always included?
No. Ask the bidder to state inclusion and responsibility explicitly, then verify local requirements.
02Is contractor financing always a bad choice?
No. Compare it independently and read the full terms. The referral alone does not show that it is the best option.
03Is an online estimate a contractor quote?
No. It is planning information. Only a contractor can price the actual agreed scope after assessing the job.
