What You Should Know About Building in Seminole County
Seminole County does things a little differently from Orange and Osceola. The county is more built-out, the lots tend to be smaller, and the regulations are tighter in some areas. That doesn't mean it's harder to build here. You just need to know what you're working with.
The Permit Process
Seminole County runs everything through an electronic plan review system, which actually makes things move a bit faster than some neighboring counties.
- Pre-application meeting - Not required, but it's a good idea if your project has any unusual features or if the lot has quirks
- Submit plans electronically through the county's online portal
- Plan review takes about 10 to 15 business days for residential projects
- Permit issuance once your plans are approved and fees are paid
- Inspections get scheduled through the county system. You can do it online.
The building department office is off Bush Boulevard in Sanford if you ever need to go in person, but most of it can be handled online.
Regulations Worth Knowing
- Setbacks vary by zoning district. A lot in Longwood might have totally different setback requirements than one in Oviedo. Check your specific property's zoning.
- Maximum lot coverage is typically 35 to 45% for residential zones. That limits how big you can build relative to the lot.
- Hurricane protection applies to all new construction. Everything has to meet Florida Building Code wind load requirements.
- Tree protection is strict in Seminole County. They don't take kindly to clearing a lot without proper permits and tree surveys.
Impact Fees (2025 Estimates)
These are approximate for a single-family home:
- Transportation: roughly $5,500
- Schools: roughly $4,800
- Parks and Recreation: roughly $1,200
- Fire: roughly $600
- Law Enforcement: roughly $400
- Total: approximately $12,500
That's on the lower end compared to Osceola County, which is one reason some people look at Seminole County even though the land costs more.
Things That Make Seminole County Unique
- A lot of Seminole County falls inside the Wekiva Protection Area. If your lot is in or near it (think areas around Wekiva Springs Road, Longwood, and parts of Sanford), you'll deal with additional environmental regulations around stormwater, septic, and clearing.
- Septic systems are still required in some unincorporated pockets without municipal sewer. The county health department handles those permits separately.
- Properties along the St. Johns River corridor have strict flood zone requirements. If you're looking at land near Geneva or along the river east of Sanford, get a flood determination early.
