Duval County
Renovating in San Marco
Masonry bungalows and mid-century ranches close to the river, where flood zone and elevation questions come before design questions.

Housing stock
What we find when we open a wall here
1920s to 1950s masonry and frame bungalows near the square, mid-century ranches south of it, and a scattering of 1990s infill. Many houses sit on low slabs or short crawl spaces at elevations close to the base flood elevation.
What San Marco does to a renovation
Flood zone and the 50 percent rule
Parts of San Marco are in a mapped special flood hazard area. When a renovation's cost reaches 50 percent of the structure's market value, the whole building has to be brought into compliance, which can mean elevating it. We check the flood map and the assessed structure value before any design work.
Elevation certificate
If your house is in an AE zone and you do not already have an elevation certificate, get one early. It changes both the design and the insurance conversation.
Masonry walls
Concrete block exterior walls make opening changes a structural item every time, with a lintel and a bearing check.
Mature trees
Live oaks near the house limit crane access and are frequently protected. We check tree regulations before planning a second-storey lift.

What people in San Marco said
Another builder quoted a bigger plan and never mentioned the flood rule. HomeRise brought it up before we spent a dollar on design.
Elena BrooksSan Marco · 620 sq ft rear addition in an AE zone
They flood tested the shower pan and sent us a photograph of the water sitting in it. Small thing, but it is the part you can never check later.

Questions
Working in San Marco
Yes. San Marco is 8 minutes from the shop, which is inside the radius we deliberately keep. It means a punch item gets handled the same week rather than waiting for someone to make the trip.
We do, as the licensed general contractor, and we carry every inspection in Duval County. We hold the licences and portal accounts for Duval, St. Johns and Clay counties.
