Screen enclosure permits in Lake Mary: city or county?
Whether a Lake Mary screen enclosure permit goes to the City of Lake Mary or to Seminole County depends on where the house physically sits, not on its mailing address. Heathrow — the largest cluster of pool cages with a Lake Mary 32746 address — is unincorporated Seminole County, so those are county permits. Inside city limits, the City of Lake Mary Building Division handles them.
The split, in one paragraph
Lake Mary the city and Lake Mary the postal address are not the same place. The 32746 delivery ZIP covers the incorporated city and the unincorporated census-designated place of Heathrow, which is roughly 1,900 homes on about 1,800 acres at I-4 and Lake Mary Boulevard. Much of the Markham Woods Road corridor is in the same position. A homeowner in that situation who calls the city about a cage permit gets sent to the county — and a contractor who files with the wrong office loses a week finding out.
This matters most on the jobs that stop being a like-for-like rescreen: rebuilding a collapsed wall, moving a knee wall, changing the footprint or adding a screen room. That is when a permit is unambiguously in play and when the office you file with becomes a real question.
If your address is inside Lake Mary city limits
The city runs its own Building Division, separate from Seminole County:
- City of Lake Mary Building Division, 911 Wallace Court, Lake Mary FL 32746
- 407-585-1441 or 407-585-1361 · permitinfo@lakemaryfl.com
- Online plan portal: gopost-lakemary.eplansoftreview.com
Three things about that office are worth knowing before you deal with it:
- SCREEN ENCLOSURE is its own permit type on the city building permit application, listed alongside RESIDENTIAL POOL and FENCE. It is not filed as a generic alteration.
- There are dedicated inspection codes — B120 “Sunroom Framing/Fastener Inspection” and B130 “Final Pool Enclosure/Screen Enclosure/Screen Room/Sunroom”. Note that B120 is a fastener inspection: the city inspects the connections, which is exactly where old cages here fail.
- Applications go null and void 180 days after filing unless pursued in good faith. A cage job that stalls waiting on an HOA decision can time out.
The Building Division enforces the Florida Building Code 8th Edition (2023) and the 2020 NEC as of 31 December 2023.
If your address is unincorporated
Heathrow is confirmed unincorporated. It files with Seminole County Development Services, Building Division — a different office, a different portal and a different inspection schedule from the city.
Before assuming which one you are: the city publishes maps at lakemaryfl.com/248/Maps. Heathrow is verified as unincorporated county. The jurisdiction of Magnolia Plantation, Heathrow Woods, Alaqua Lakes, Carisbrooke, Shannon Downs and Hanover Woods was not verified for this page.
Setbacks: the thing that catches rebuilds
Lake Mary’s code of ordinances carries a dedicated section, POOL AND SCREEN ENCLOSURE SETBACK REQUIREMENTS. Per the published section, pools must sit no less than ten feet from the rear property line, and screen enclosures must meet the side-yard setback of the property’s zoning district.
That only becomes your problem when the job stops being a rescreen. A cage built decades ago may sit in a position that is grandfathered but not re-buildable in the same footprint. If a wall has come down, ask about setbacks before anyone quotes you a rebuild.
Trees: a separate application
The City of Lake Mary requires a separate arbor permit application whenever trees are to be removed — the question is printed directly on the standard building permit application. This is a protected-canopy city, and that has a direct bearing on screens: overhanging live oak and laurel oak limbs are the biggest recurring cause of torn panels and algae staining along Country Club Road and the Markham Woods corridor. You cannot simply cut the offending limb back without checking the arbor rules first.
Wind speed: what your cage is actually engineered to
Seminole County publishes Ultimate Design Wind Speeds of 129 mph for Risk Category I, 139 mph for Risk Category II and 149 mph for Risk Category III/IV. The Florida Building Code permits screen enclosures to be designed to Risk Category I wind speeds, so 129 mph is the number that governs a residential pool cage here.
At 139 mph for Risk Category II the county sits below the 140 mph wind-borne debris region threshold, and it has no coastal exposure. Seminole County is not in the High-Velocity Hurricane Zone — that is Miami-Dade and Broward. If a contractor’s spec sheet cites HVHZ requirements for a Lake Mary job, they have copied it from somewhere else.
The practical consequence is the failure mode you have probably already seen: local cages are engineered to a materially lighter wind load than coastal cages, so in a storm the aluminium frame survives and the mesh pulls out of the spline channel. Rescreen, not rebuild.

Permits, HOAs and insurance
Do I need a permit to rescreen my pool cage in Florida?
Honest answer for Lake Mary: not established in writing, and this site will not pretend otherwise. Contractor blogs across Florida state that like-for-like mesh replacement on an unmodified frame is exempt while any framing, anchoring, geometry or footprint change requires a permit — but no primary City of Lake Mary or Seminole County document confirming that exemption was located. What is confirmed is that SCREEN ENCLOSURE is a listed permit type on the city’s building permit application, with its own inspection codes. Call the Building Division at 407-585-1441 or email permitinfo@lakemaryfl.com and get the answer for your specific scope.
Do I need HOA approval for a screen enclosure?
Separate from any building permit, and yes for most of Lake Mary. Heathrow, Heathrow Woods, Magnolia Plantation, Timacuan, Steeple Chase, Tuscany, Hills of Lake Mary and Huntington Pointe all operate active associations, and Huntington Pointe has its own recorded governing documents. A like-for-like rescreen in the same colour usually raises no architectural question; a colour change, a frame change or a new structure does.
Is pool screen damage covered by homeowners' insurance in Florida?
It depends on your policy’s treatment of screen enclosures, which is frequently a separate limit or a separate deductible from the dwelling. Central Florida saw significant pool enclosure damage from Hurricane Ian in 2022 and from Helene and Milton in 2024. Read your declarations page for the screen enclosure line before you assume either way, and photograph the damage before anything is removed.
