Home inspections in St. Johns County
St. Johns County covers two entirely different housing markets that happen to share a county line. In the north and west it is one of the fastest-growing suburbs in Florida — Nocatee, World Golf Village, the CR 210 corridor — where the houses are new and the questions are about builder workmanship and drainage. In and around St. Augustine it is the oldest housing stock in the state. We inspect across all of it, and we adjust the inspection to the era of the house rather than running the same script. Median stock here runs Bimodal: a pre-1940 historic core in and around St. Augustine, and a very large 2000–present suburban build-out north and west, which is the single biggest predictor of what an inspection turns up.
The county splits cleanly by build era. Anything pre-1940 gets the historic treatment: masonry and coquina moisture, balloon framing, knob-and-tube remnants, galvanized supply, and undocumented additions. Anything 1950 to 1990 gets a hard look at the panel, the drain lines, and the roof deck attachment. Anything post-2000 is an attic-and-envelope inspection — duct sealing, truss modifications, bath fan termination, grade at the slab edge, and stucco or siding detailing. Coastal parcels east of I-95 add salt corrosion on mechanical and electrical equipment and require careful documentation of opening protection for insurance.
What comes up repeatedly on St. Johns County inspections
Flood exposure is the county-wide constant, and it takes three forms: Atlantic surge on the barrier islands, tidal and Intracoastal flooding along the Tolomato and Matanzas, and stormwater ponding in the newer inland subdivisions. Growth is the other constant. The volume of construction over the last two decades means a lot of houses were built and remodeled during periods when good trades were fully booked, and workmanship variation shows. Add three permitting authorities — the county, the City of St. Augustine, and St. Augustine Beach — and permit history verification takes real attention. An inspector who works this county regularly checks these first.

Historic coastal building stock in St. Johns County
Pre-1940 masonry, coquina, and balloon-framed housing in a salt-air, high-water-table environment, with a century of undocumented modifications layered on top.
Old coastal houses fail slowly and quietly, which is exactly why they need a careful inspection rather than a fast one. The two forces at work are water and time. Salt air and a high water table drive moisture into masonry and framing from below and outside, while eighty or a hundred years of owners have each solved a problem their own way — a bathroom added over a floor joist that got cut for the drain, a rewire that stopped at the accessible walls, a stucco patch over a crack that was structural. None of that shows up in a listing photo. What we do in these houses is separate the cosmetic from the structural: what is simply old and working, what is old and at the end of its life, and what somebody did in 1978 that is now holding up a floor. The report should tell you which is which, with photos, so the price conversation is about facts.
What this building stock produces on an inspection
- Balloon framing with no fire blocking between floors, and notched or drilled joists from later plumbing runs
- Knob-and-tube remnants left live in attics and wall cavities after a partial rewire
- Coquina, brick, and stucco-over-masonry walls sealed with modern latex or elastomeric coatings that trap moisture in the wall
- Original single-glazed wood windows with failed glazing putty, rotted sills, and no impact rating
- Additions, enclosed porches, and converted outbuildings with no permit record
- Crawl space and pier foundations with sistered, shimmed, or rotted framing and inadequate ventilation
- Galvanized supply and cast-iron drain lines at or past end of service life
- Roof framing modified for later dormers or attic conversions without engineering

St. Johns County: permitting, wind, flood and insurance
Permit records for St. Johns County are held by St. Johns County Building Department.
Permits in unincorporated St. Johns County are issued by the St. Johns County Building Department; the City of St. Augustine and the City of St. Augustine Beach run their own permitting inside their limits, and St. Augustine adds historic-district architectural review on top. That split matters when we find work that was never inspected. Re-roofs, window and door replacements, HVAC changeouts, water heaters, electrical panel swaps, and structural additions all require a permit. When we flag an addition or an enclosed porch with no permit history, the fix is a records search at the correct jurisdiction before closing — not after.
St. Johns County sits in the coastal band of the Florida Building Code wind map. Ultimate design wind speed (Vult) for a Risk Category II home runs near 130 mph along the Atlantic and eases as you move inland toward the county's western edge. Because the contour crosses the county rather than stopping at it, the governing number is site-specific — the Building Department confirms it at permit review. St. Johns County has long designated its wind-borne debris region as the area east of Interstate 95, and the statewide Florida Building Code rule also pulls in anything within one mile of the coastal mean high water line where Vult is 130 mph or greater. In practice, that covers St. Augustine, St. Augustine Beach, Anastasia Island, Vilano, and Ponte Vedra Beach. Inside that region, every glazed opening — windows, glass doors, skylights, and the garage door — needs impact-rated product or an approved shutter system.
Flood exposure here is layered: Atlantic surge on Anastasia Island and Vilano, Intracoastal and tidal creek flooding along the San Sebastian and Tolomato, and stormwater ponding in the flatter inland subdivisions. AE and VE zones are common downtown and on the islands, and older buildings frequently predate the current flood maps.
Carriers writing in St. Johns County want two things on older homes: a 4-point inspection covering roof, electrical, plumbing, and HVAC, and a wind mitigation report on form OIR-B1-1802. Requirements vary by carrier. Confirm with your insurance agent, your realtor, or your lender whether a 4-point is needed — we can include it with your inspection. Because so much of the county is in the wind-borne debris region, the opening protection line on the wind mit form is worth real money here. Documented impact glazing or code-approved shutters on every opening moves the premium more than any other single item.

What this means for your policy
A wind mitigation inspection documents roof covering, roof deck attachment, roof-to-wall connection, roof geometry, secondary water resistance and opening protection. Those seven items drive the wind credits on a Florida policy. On a St. Johns County home it is usually the cheapest way to move a premium, and it can be bundled into the same visit as the home inspection.
