Onsite Planning for an RTM Project Part 3: Code Compliant Basement Finishing.

We are nearing the end of the onsite project series. With only part 4 remaining, you will soon have all of the information you need to shop and prepare for your RTM project onsite work, while having a good understanding of what happens before you officially move into your brand new home.

If you missed part 1 and 2 of this series, you can still read them here on the B&B Homes blog.

Part 3 of this series focuses on what you need to do to complete your basement before you move into your RTM while being compliant with local codes.

Rim Joist Installation

  • Rim joists need to be insulated once the house is set on the foundation. At B&B, we recommend using spray foam as you get a better seal but batt insulation and poly can also be used
  • Once the spray foam is applied, it must be covered by a fire resistant insulation such as Rockwool
  • If the rim joists are left uninsulated for a long period of time, this will lead to damage to your new home. Humidity levels will rise as the colder outside air mixes with the warmer inside air

*Please keep in mind, humidity issues of any kind are not covered by B&B Home’s warranty as it falls under proper home care maintenance.

Installation of Drywall for Basement Foundation Wall

  • The Styrofoam blocks that B&B Homes uses in ICF foundations have plastic fastening strips every 8” and this is indicated on the surface by a diamond pattern. These particular strips have higher pull out strength then a dimensional stud
  • The easiest way to get the drywall into the basement is through a window opening. Keep this in mind when designing your basement and make sure you have at least one window that is big enough to accommodate this
  • ICF walls must be drywalled before you move in as code requires
*Although mudding, taping, and painting aren’t required at this stage, you will want to consider having this done prior to your move in, for a smoother transition with less of a mess to deal with later on when finishing.

Other Miscellaneous Items to Be Code Compliant

  • Temporary or permanent handrails/railing must be constructed on your basement stairs as per code
  • You will need to have exterior doors leading onto a deck or landing with stairs and railing
