The limit
Where the 7 in the Ebro limit comes from
The figure is set in section R402.4.1.2 of the Florida Building Code, Energy Conservation, 8th Edition (2023). It applies in Climate Zones 1 and 2, and Table R301.1 places Washington County, Ebro included, in Climate Zone 2.
Air changes per hour
How many times the air inside the house would be replaced in an hour while the house is held at the test pressure.
50 pascals
The test pressure the fan holds the house at while the leakage is measured.
Measured on the house
The reading comes from the test on the built shell, not from the plans.

Small plans and large plans
A small plan and a large one face the same 7, since the figure is already scaled to the size of the house. What changes is how much each gap weighs. A compact house has less air to spread its leaks across, so the same gap moves its reading further than it would in a large house.
On a builder list with several plan sizes, the smaller plans are where careful sealing around each opening matters most.

The result
What the reading tells you
Over 7
The leaks are corrected and the house is tested again under the same conditions.
Not where the leaks are
It does not point to a wall, a room or a fixture. Finding the gaps is part of correcting them.

Builders
Testing several houses for one builder in Ebro
A builder with more than one new house in Ebro can book them together. Each house has its own test and its own reading.
One call for the list
Send the address, permit number, ready date and site contact for each house.
A date for each house
Each house gets a test date when its own shell is done.
Changes by house
When one house on the list slips, call with that address and its new ready date.

In the build
Where the test sits in each house on the list
After the shell is closed
Once the last opening through the walls, ceiling and floor is made on that house, it can be tested.
While finishes go on
Painting, flooring and cabinet work do not change the reading, so they need not be done first.
Ahead of the finish date
Testing early in the finish stage leaves time to correct leaks and run a retest on that house before it has to be done.
Before the attic is insulated
Top plates, light cans and duct boots are easiest to reach from the attic before the insulation covers them.

Before the date
Where a new house leaks
Around windows and doors
The space between each frame and its rough opening, before the trim covers it.
Chases and shafts
Framed chases for a flue or ducts that open from the attic down into the walls.
Service entries
Where the electric, cable and phone lines come into the house.
Recessed lights
Each can set into a ceiling under the attic has a gap around its housing.
Vent stacks
Each plumbing stack that rises through a top plate and out the roof leaves a gap at both.
Attic access
A hatch or pull-down stair with no weatherstripping around its edge.
Kitchen soffits
A boxed soffit over the cabinets can open into the attic above it.
Behind the tub
A tub set against an outside wall hides that stretch of wall, and the drain opening under it, once it is in.

Service side
Openings where lines leave the house
Hose bibs
Each outdoor spigot passes a pipe through an outside wall.
Condensate drain
The drain line from the air handler runs out through a wall or the slab edge.
Gas line
Where the gas line enters from the meter to a range, water heater or fireplace.
