Foundation work in Florida is regulated twice over: the contractor needs a state license, and the job itself usually needs a local building permit. This post sets out what Orange County publishes about permits for structural repairs, including plans sealed by an engineer and the Notice of Commencement, and where homeowners in other parts of Central Florida should check instead. It quotes the county's pages so you can read the rules in their own words.
We connect Orlando-area homeowners with independent Florida-licensed contractors for free, no-obligation foundation repair quotes. The contractor you choose quotes, contracts and does the work, including pulling any permit the job needs.
Orange County's rule for structural repairs
Orange County says structural repairs to foundations need a permit. Its Storm Repair and Permit Information page lists, under "Types of Work That Require a Permit": "Structural repairs for damage to walls, beams, foundations, or trusses." The county's "Do I need a permit?" page adds that "additions and alterations require a building permit" and that "anytime you are pouring concrete or placing pavers, a permit is required."
No Orange County page found for this research names "sinkhole", "grouting" or "underpinning" specifically. The structural-repair language above is the closest official statement, and the county's Division of Building Safety, (407) 836-5550, is the place to confirm how it applies to a particular job. Applications go through the county's Fast Track online system.
These rules cover unincorporated Orange County. That includes Pine Hills, a Census-designated place rather than a city, so Orange County permits apply there. Homes inside a city such as Orlando or Winter Park fall under that city's building department.
When plans must be signed and sealed by an engineer
Orange County's Alterations, Renovations and Repairs page defines repairs as "the reconstruction or renewal of any part of an existing building for the purpose of its maintenance or to correct damage." It says: "Construction plans are required in most cases. However, construction plans are only required to be signed and sealed by a Florida Licensed Professional Engineer or Registered Architect when repairs are made to components which may affect the structural stability of a building or structure." Documents must be "properly signed, dated and sealed," and a detailed scope of work is required.
Underpinning, piering and structural sinkhole stabilization change how a house is supported, so in practice they are the kind of work this rule describes. That ties the permit to Florida's engineering law: only a Florida-licensed professional engineer (PE) may diagnose the cause of foundation movement and design a structural repair, and a contractor may install a PE-designed repair (§471.003(2)(f)). A contractor's free evaluation is a sales estimate, not sealed engineering. Our page on inspections and engineer reports explains the difference.
Notice of Commencement over $5,000
The same storm-repair page says that "if value of work exceeds $5,000," a Notice of Commencement is also required. Most structural foundation jobs pass that figure: national guides put a typical overall foundation repair at $2,200 to $8,100, settling or sinking foundations at $4,500 to $20,000 and major leveling at $20,000 to $23,000 (This Old House, Bob Vila, HomeGuide and Angi, 2026; estimates, not quotes). See the foundation repair cost guide for more ranges.
Permit fees for Orange County were not retrieved for this site. National guides list permits at about $75 to $150, but ask the contractor what the permit and any engineering will cost and whether those are in the quote.
Who pulls the permit: contractor or owner-builder
Orange County states: "A licensed contractor will be required to accept permit issuance. An owner-builder may act as Contractor under Exemption to F.S. 489.103(7)(a)." In other words, the county expects either a licensed contractor or an owner using the owner-builder exemption to take responsibility for the permit.
For structural foundation work, the contractor's license matters too. In Florida, structural foundation repair, underpinning and sinkhole stabilization of a house is Division I contracting: a certified or registered general contractor (CGC/RGC) or residential contractor (CRC/RRC) clearly qualifies, and a building contractor (CBC) arguably does for homes up to three stories (§489.105(3)(a)–(c)). Florida has no separate foundation or underpinning specialty license. The license number must appear in a contractor's ads and contracts (§489.119(5)(b)); check it on MyFloridaLicense.com, and remember that a county business tax receipt is not a license. More detail is in our contractor license guide.
Why unpermitted work causes trouble later
Orange County is direct about this: "Work completed without a permit that is discovered by a home inspector or title company may affect your ability to obtain homeowner's insurance, prevent the sale of your home." A closed permit with a final inspection is part of the paper trail a future buyer, lender or insurer may ask for. Our post on selling a house with a sinkhole history covers the disclosure side.
Seminole County, as its FAQ puts it
Seminole County's permit FAQ says: "The code requires that a lot of documents be signed and sealed by a Florida Registered Professional, mainly the ones involved with the exterior of a structure, structural stability and safety related items." On unpermitted work, the same document warns of a notice of violation, "double the permit fee," and possibly "costly fees for third party engineering analyses ... for areas of work that have been concealed." Seminole's permit-type list does not include a foundation or sinkhole category, so the Building Division is the place to confirm how a repair is classed.
Osceola, Lake and the cities: confirm locally
For Osceola County, Lake County and cities such as Orlando, Kissimmee, Sanford, Clermont, Altamonte Springs, Winter Springs, Winter Park, Casselberry and Longwood, permit rules vary; the licensed contractor confirms and pulls any permit. No published foundation-specific rule was found for these jurisdictions. Some cities also have historic districts, such as in Sanford and Winter Park, where exterior work can need design review, so confirm locally before work is scheduled. Local notes are on our service area pages.
The engineer's completion report for insured sinkhole repairs
For repairs paid under a verified sinkhole loss, Florida law adds a separate record. Section 627.7073(3) says: "Upon completion of any building stabilization or foundation repairs for a verified sinkhole loss, the professional engineer responsible for monitoring the repairs shall issue a report ... and certifies ... that such repairs have been properly performed," and must "file a copy ... with the county clerk of the court, who shall record the report and certification." That report is in addition to the local permit and final inspection.
Ask your insurer what your policy covers. This is general information, not legal or insurance advice.
A short permit checklist
- Who is pulling the permit, and under which license number?
- Will the plans be signed and sealed by a Florida PE or registered architect?
- Does the job value call for a Notice of Commencement?
- Which inspections are scheduled, and who attends them?
- Will you receive the closed permit and, for insured sinkhole work, a copy of the engineer's completion report?

Frequently asked questions
Does foundation repair need a permit in Orange County?
Orange County lists structural repairs for damage to walls, beams, foundations or trusses among work that requires a permit. Plans are required in most cases and must be signed and sealed by a Florida-licensed engineer or registered architect when repairs affect structural stability. A Notice of Commencement is also required when work exceeds $5,000. Confirm details with the Division of Building Safety.
Can a homeowner pull a foundation repair permit?
Orange County says a licensed contractor will be required to accept permit issuance, and that an owner-builder may act as contractor under the exemption in section 489.103(7)(a) of the Florida Statutes. Owner-builder status carries its own responsibilities, so read the county's requirements first. Structural plans still need a Florida PE or registered architect's seal when stability is affected.
What happens if foundation work was done without a permit?
Orange County warns that work completed without a permit and discovered by a home inspector or title company may affect your ability to obtain homeowner's insurance or prevent the sale of your home. Seminole County's FAQ mentions a notice of violation, double the permit fee and possible third-party engineering costs for concealed work. Ask the local building department how to resolve it.
