Owner-builders

When you are the one booking the test

On a house you are building yourself, the booking and the timing fall to you rather than to a general contractor. Tests are booked through our office at 511 S Highway 71 in Wewahitchka.

  • Line up your trades

    Your plumber, electrician and air conditioning installer each cut openings through the walls and ceiling. The code allows the test once the last of those openings has been made, so ask each trade when their last one will be.

  • What to send

    The address, the permit number, the date the house will be ready and the name and number of someone who can open it.

  • Leave room

    Set the date with time to spare before you need the result, in case the first reading comes back high.

  • If your schedule moves

    If the shell will not be closed on the date you gave, call and a new test date is set.

Test day

How the house is set up for the test

A custom house can have more dampers and doors to set than a plain plan, so walk through it the day before.

  • Windows and exterior doors

    Closed and latched, but not taped or sealed, so the test measures the house as it was built.

  • Fireplace and stove doors

    Shut, including glass doors on a fireplace.

  • Dampers

    Exhaust, intake and flue dampers closed: the range hood, the bath fans, the dryer vent, any fresh-air intake and the fireplace flue.

  • Interior doors

    Open wherever doors are hung, so every room sits at the same pressure.

  • Heating and cooling

    Turned off, so the equipment is not moving air during the test. On a house with two systems, both are off.

  • Registers

    Supply and return registers fully open where installed, with any tape or construction covers taken off.

Custom plans

Attics, garages and extra rooms on a custom house

A custom plan can put parts of the house on either side of the measured boundary, and how each part is built decides whether the test counts it. Mention these when you book.

  • Attic sealed at the roof deck

    Opened to the house on test day and measured with it. A vented attic is left out of the test, and the ceiling below it is the boundary.

  • Attached garage

    Outside the test when it is not heated or cooled. The wall and door it shares with the living area are part of the boundary.

  • Workshop or storage room off the garage

    A room that is not heated or cooled stays outside the test, and the wall between it and the house counts.

  • Room over the garage

    When it is heated and cooled, it is inside the shell, and the floor between it and the garage is part of the boundary.

Rental property in Panama City Beach

Panama City Beach has a mix of resort and rental property, and a house built for rental use is held to the same test as one built to live in. If the owner will not be on site, the site contact on the booking should be someone who can let us in on the day and who knows when the shell will be closed, such as the builder or a property manager. The owner can still be the one who books.

Before test day

Openings an owner-builder can look over

Air moves through a new house wherever the shell has been cut or pieced together, and gaps are easier to reach before tile and trim cover them.

  • Behind the tub and shower

    Where a tub sits against an outside wall, or its drain drops through the floor, the openings behind it are hard to reach once the tile is up.

  • Around windows and doors

    The gap between each frame and its rough opening should be filled before the trim covers it.

  • Air conditioning lines

    The refrigerant lines and the condensate drain pass through an outside wall on their way to the outdoor unit.

  • Fireplace chase

    The framed chase around a flue can open from the living space into the attic or the wall.

  • Outdoor lights and outlets

    Each box set in an outside wall is an opening until it is sealed and the fixture is on.

  • Plumbing vents

    Each vent pipe rising through the ceiling to the roof needs the gap around it closed.

  • Air handler closet

    A closet built around the air handler, with a framed return, can open into the attic or the wall cavities around it.

  • Soffits over the cabinets

    A framed soffit above the kitchen cabinets, or a chase for ducts, can open straight into the attic.

Adding on to a house you already own

Owners who are adding a room rather than building a whole house may not need the test at all. The code makes an exception for additions and alterations that make up less than 85 percent of the building shell. A project at or above that share is tested the same way as a new custom house, with the same setup on the day.

The limit and the retest

Section R402.4.1.2 of the Florida Building Code, Energy Conservation, 8th Edition (2023), sets the limit for new houses at 7 air changes per hour at 50 pascals, and Panama City Beach is in Climate Zone 2 with the rest of Bay County. A house that reads over the limit has its leaks corrected and is tested again under the same setup, once every correction is finished.

Test day and the finish work

A fan is fitted in an exterior doorway and holds the house at the test pressure while the leakage is measured, and the house ends with one reading. Custom finishes do not need to be done first. Paint, flooring, trim, cabinets and countertops do not change that reading, so the finish work can carry on after the test.

FAQ

Panama City Beach blower door questions

Have another question? Call (850) 819-6031.

Does a pool or outdoor kitchen affect the test?
No. Pools, outdoor kitchens and pool equipment sit outside the shell. Only the pipes and wires that run from them into the house through a wall count as openings.
Does the fireplace need to be finished for the test?
The firebox, the flue and the damper need to be in, because the flue passes through the shell. The stone, tile or mantel around it are finishes and can wait.
Is a screened porch part of the test?
No. A screened or open porch sits outside the heated and cooled space. The wall, windows and door between the porch and the house are part of what is measured.
Does a vaulted ceiling change anything?
Not the test itself. A vaulted or cathedral ceiling is part of the shell, so any light, fan or vent cut through it counts as an opening the same as one in a flat ceiling.
Is a sunroom part of the test?
A sunroom that is heated and cooled along with the house is inside the test, so its glass, walls and roof are part of the boundary. An unheated sunroom is treated like a porch.
What about a whole-house fan?
A whole-house fan is a large opening in the ceiling. Its louvers or cover need to be closed for the test, like a damper.
