What Lake Mary homeowners need to know before work starts
Do You Need a Permit for a Home Renovation in Lake Mary, and Which Office Handles It?
Most structural, electrical, plumbing, and roofing work requires one. Which office you file with is the part that trips up contractors who don't know the area.
Properties inside Lake Mary city limits file through the City of Lake Mary's Building Division, which processes permits through its online portal and enforces the 2023 Florida Building Code, 8th Edition. Properties in unincorporated Seminole County, which includes Heathrow, the Markham Woods corridor, and other pockets that carry a Lake Mary mailing address but sit outside city limits, file through Seminole County's Development Services Building Division instead. As of December 2025, Seminole County moved to mandatory electronic plan review through its ePlan platform.
The two offices are separate and run on different timelines. We check the parcel. Then we file, in house, and carry it through from there.
For properties in Heathrow or other HOA governed communities, exterior changes require written architectural review approval before permits are submitted. We handle both and sequence them correctly so neither process holds up the other.
