GENERAL., Attacb the ledger boarc� which shall be
equal to or gi�eater fhan thejoist size, to the. existing
exterior wall in accordance with- Figure 14. through
Figure 16. When attachments are made to the existing
house band joist, the band joist shall be capable of
supporting the now decl�. If this cannot be verified or
conditions at the existing house differ from the details
herein, then either a free-standing deck or full plan
submission is required. See FREE-STANDING DECKS.
SIDING AND FLASMNG: House siding, or the
exterior finish system, must be removed prior to
installation of the ledger board- Approved corrosion
resistant -flashing is required at any ledger board
connection to a wall of wood fiamed construction (sea
MININfUM REQUMMENTS). See Figure 14 for
continuous flashing with drip edge.
MANUFACTURED WOOD JOIST: The tenn "I -
Joist" denotes manufactured wood "I" joists (see Figure
13A). Many new homes constructed with wood 1 -joists
include 1 11 or tblckor engineered wood products (EWP)
such as oriented strand board (OSB) or structural
composite lumber (SCL) including laminated veneer
Figure 13A- Wood 1 -Joist Profile
lumber (LVL) — as band joists (or r! m' boards) that can
support lbe attachment of a deck (see Figure 14).
However, some older homes might be constructed with
band boards that are too thin (3/4" or thinner) to support
a deck. In such cases, a froe-standing dark or a full plan
submission is required.
MANUFACTURED WOOD TRUSS: A metal plate
connected wood truss (MPCWT) is an engineered,
prefabricated structural component designed for each
specific -application. WCWT's used in residential floors
are often installed with i 2x4 lumbar "ribbon"at the
ends of the trusses (see Figure, 1313), the purpose of
which is to tia the ends of the trusses together. The
ribbon board, by itself, is not intended to Support the
deck ledger and deck. Installing residential decks when
the floor system for the house uses MPCWT requires a
standard detail provided by the truss designer, a free-
standing deck, or a full plan submission. R�&r to the
