Seminole County sits in the fast-growing north Orlando metro, and its building permits are issued by the Development Services Building Division for unincorporated Seminole County. As of December 2025, the county transitioned to mandatory electronic plan review — all building permits now process through the ePlan platform.
This Seminole County building permit guide covers what requires a permit, how fees work, the ePlan submission process, trade permits, and inspections — so your Sanford-, Oviedo-, or Winter Springs-area project starts clean.
Confirm you're in unincorporated Seminole County. The Building Division permits only the unincorporated county. Seminole's cities — including Sanford, Lake Mary, Altamonte Springs, Casselberry, Longwood, Oviedo, and Winter Springs — run their own building departments with separate processes and portals.
What requires a building permit in Seminole County?
Under the Florida Building Code (§105.1), a permit is required before you construct, alter, repair, move, demolish, or change the occupancy of most structures and systems. Common triggers include:
Permit required
- New construction, additions, and tenant build-outs
- Structural / load-bearing alterations and demolition
- Roof replacements, window and door replacements, and exterior work
- Electrical service changes and most wiring alterations
- Mechanical / HVAC installations and changeouts
- Plumbing alterations, repipes, and water heaters
- Swimming pools, spas, sheds, and fences
- Solar PV systems and screen enclosures
Typically exempt
- Painting, flooring, cabinetry, and cosmetic work
- Like-for-like minor repairs not altering systems
- Certain low non-structural fences (confirm limits)
- Routine maintenance not extending or rerouting systems
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Beginning without one exposes the owner to after-the-fact fees and penalties. Online permitting requires a current contractor license in the county database; owner-builders must apply in person with photo ID.
Who handles permitting in Seminole County?

Seminole County permit types
A building permit is one record among many. The Seminole County Building Division issues work under separate record types, and filing under the wrong one is a rejection, not a correction — the application is closed and refiled, and the review clock restarts. Seminole adds a sequencing rule most counties do not: you request an application number through Building Permits Online first, then complete the submittal in ePlan, so the record type is fixed before the documents are ever uploaded.

Solar permits in Seminole County
Solar is permitted as its own record type in most Florida jurisdictions rather than rolled into a general building permit, and residential and commercial photovoltaic are usually separate records with different document sets. Solar thermal — passive water and pool heating — is a third, distinct record.
A photovoltaic submittal is reviewed on two tracks at once: structural (roof load path, attachment spacing, uplift) and electrical (conductor sizing, rapid shutdown, point of interconnection). A single-line diagram and a signed and sealed structural attachment detail are the two attachments most often missing on a first submittal.
Under Fla. Stat. §163.04, a homeowners' association cannot prohibit a solar collector on a dwelling — HOA architectural approval is not a prerequisite to permit issuance, though it may still be a contractual matter between owner and association.
Utility interconnection runs parallel to the building permit, not inside it. Permission to Operate is issued by the utility after the final electrical inspection clears.
Roofing permits in Seminole County
A roof covering replacement requires a permit in every Florida jurisdiction. Repairs below the local threshold may not, but the threshold is scope-specific and confirming it with the building department before tear-off is cheaper than an after-the-fact permit.
Every roof product must carry a current Florida Product Approval or Miami-Dade Notice of Acceptance rated for the wind speed at the project address. A product approval number that has lapsed or is rated below the site wind speed is the single most common reroof rejection.
Reroof inspections are sequenced: dry-in after the underlayment, nail-off on the sheathing fastening, and final. Covering the deck before the dry-in inspection means tearing it back open.
Hurricane mitigation retrofit requirements can attach when an existing roof is replaced, including secondary water barrier and roof-to-wall connection work. These add scope and documents, and they are triggered by the replacement itself.
Under Fla. Stat. §553.7922, jurisdictions run expedited procedures for permits that need no technical review — reroofs, roof repairs, and similar — during a declared state of emergency.
Seminole is inland Orlando-metro territory, running roughly 130 mph ultimate design wind speed with no coastal exposure and no wind-borne debris region requirement. Product approval must still be rated for the wind speed at the project address. Because building, zoning, and fire review are handled in-house rather than routed to outside agencies, a reroof that does trigger a secondary review generally stays inside one building, which is a meaningful schedule advantage over the multi-agency counties nearby.
Seminole County building permit cost
Seminole County building fees are based on the type and valuation of work, with separate fees for each trade and a state surcharge. Over-the-counter intake at the Building Division office carries additional fees as outlined in the Seminole County Administrative Code.
Because fee schedules are adjusted periodically, confirm current amounts in Building Permits Online or with the Building Division before budgeting. Impact fees may apply to qualifying new construction.
| Fee component | How it works |
|---|---|
| Building / construction fee | Based on type and valuation of work; minimum fees apply |
| Trade permits (E / P / M) | Charged separately per trade unless rolled into a master permit |
| Over-the-counter intake | Additional fees per the Seminole County Administrative Code |
| Impact fees | Assessed on qualifying new construction |
| State surcharge | DBPR surcharge added per Florida statute |
| Work-without-permit | After-the-fact fees and penalties |

Seminole County trade permits
Electrical, plumbing, and mechanical work generally needs its own permit and licensed contractor, each filed against the master building permit.
Electrical permits
Required for service installations, panel upgrades, solar PV, and most wiring alterations. Seminole enforces the electrical provisions of the Florida Building Code.
Plumbing permits
Required for new plumbing, repipes, water heater changeouts, fixtures, and gas piping. Fees follow the county schedule with a per-permit minimum.
Mechanical (HVAC) permits
Required for HVAC changeouts, ductwork, and refrigeration. Specialized systems are permitted and inspected separately.
Miscellaneous & specialty
Roof replacements, pools and spas, sheds, and fences are permitted separately. Use roofing and opening products with current Florida Product Approval rated for the local wind speed.
Verify your contractor's license. Confirm the contractor is licensed in Florida (the Florida DBPR at (850) 487-1395) and current in Seminole County's contractor database before applying online. The property owner is responsible for ensuring a permit is obtained.

Frequently asked questions
Who issues building permits in Seminole County, Florida?
The Seminole County Development Services Building Division issues permits for unincorporated Seminole County. Cities such as Sanford, Lake Mary, Altamonte Springs, Oviedo, and Winter Springs run their own building departments.
How do I get a building permit in Seminole County?
Confirm the parcel is unincorporated, request an application number through Building Permits Online, and submit plans through the mandatory ePlan platform (owner-builders apply in person). After review and fee payment, schedule inspections through Building Permits Online.
Does Seminole County require electronic plan submission?
Yes. As of December 2025, Seminole County transitioned to mandatory ePlan electronic plan review; building permits now process exclusively through the ePlan platform.
How much does a Seminole County building permit cost?
Fees are based on the type and valuation of work, with separate trade fees and a state surcharge; over-the-counter intake carries additional fees. Confirm current amounts before filing.
Can owner-builders apply online in Seminole County?
No. Owners acting as their own contractor must apply in person at the Building Division office with a valid government-issued ID; online application requires a current contractor license in the county database.
Which Seminole County cities issue their own building permits?
Sanford, Altamonte Springs, Casselberry, Lake Mary, Longwood, Oviedo, and Winter Springs each run their own building departments. The Seminole County Building Division permits unincorporated Seminole only — including Heathrow, Chuluota, Geneva, and the unincorporated pockets between the cities along SR 434 and SR 46. Seminole is small and heavily incorporated, so the mailing address is an especially unreliable jurisdiction indicator; confirm the parcel before filing.
Do I need a permit to install solar panels in Seminole County?
Yes. Photovoltaic installations in Seminole County are permitted under a dedicated solar record type reviewed on both a structural and an electrical track. Solar thermal — passive water and pool heating — is a separate record. Under Fla. Stat. §163.04 a homeowners' association cannot prohibit a solar collector, so HOA approval is not a prerequisite to permit issuance. Utility interconnection and Permission to Operate run in parallel with the permit, not inside it.
Does a roof replacement require a permit in Seminole County?
Yes. A roof covering replacement requires a permit in every Florida jurisdiction, including Seminole County. Products must carry a current Florida Product Approval or Miami-Dade Notice of Acceptance rated for the wind speed at the project address, and inspections are sequenced — dry-in, nail-off, then final. Some minor repairs fall below the permit threshold, but the threshold is scope-specific.
What is the difference between a residential and a commercial permit in Seminole County?
Residential work is generally a single-discipline review filed as a master permit with trades filed against it. Commercial work in Seminole County runs concurrent review across building, fire, and zoning, requires signed and sealed plans for every affected discipline, and can carry impact and concurrency fees on top of permit fees. Change of use adds accessibility and life-safety review.
Do trade permits need to be pulled separately in Seminole County?
Yes in most cases. Electrical, plumbing, and mechanical work is permitted separately by the licensed contractor for each trade and filed against the master building permit. Each trade permit carries its own fee and its own inspection sequence.
What happens if I file under the wrong permit type in Seminole County?
The application is rejected rather than corrected. Seminole County Development Services Building Division closes the record, the filing is resubmitted under the correct record type, and the review clock restarts from zero. Confirming the record type before filing is the cheapest step in the entire process.
Can I apply for all Seminole permit types online?
Mostly, with two real limits. All building permits now process through ePlan, and records and inspections run through Building Permits Online seven days a week, though the portal goes down overnight. To apply online at all, the contractor license must be current in the county’s contractor database — a lapsed registration blocks the filing before the record type matters. Owner-builders must apply in person with valid government-issued photo ID.
