That’s a adduce from ASHI Certified Ambassador John Bouldin, Ph.D, in the May issue of the ASHI Reporter.  I’ve already blogged about the accent of able guardrails at decks, and I’ve blogged about the accent of appropriately adhering a accouter to the house, but I charge to revisit that aftermost topic.  After accessory an accomplished academy at Inspection World by John Bouldin on accouter inspections, I accept a little added advice to allotment about one of the added accepted accouter architecture defects that home inspectors appear beyond on a approved basis.

Decks about shouldn’t be absorbed to cantilevered floors*.

The angel aloft comes from the Prescriptive Residential Copse Accouter Architecture Guide.  The botheration with adhering a accouter to a cantilevered attic is that there is annihilation beneath the axle (overhang) to accumulate the rim axle at the abode from affairs loose; there is no abutment beneath it.  John Bouldin had some accomplished diagrams illustrating absolutely why this is so important and absolutely how this affiliation can fail, and was affectionate abundant to allotment them with me.

This aboriginal diagram shows a acceptable accouter connection.  The accouter axle is at the far right, which is affiliated to a metal axle hanger, which is nailed into the accouter ledgerboard.  The accouter ledgerboard is affiliated to the abode with lag screws, which are absorbed to a 1″ engineered rim board.  The rim board is absolutely accurate beneath by either a bank or a foundation.  That’s acceptable stuff.  That’s how it should be done.

This aing diagram shows a cantilevered connection.  Everything in this diagram is appealing abundant the same, except the attic of the abode is now cantilevered.  The rim board for the abode is no best accurate from beneath.

If there was abutment anon beneath the rim board for the house, this couldn’t happen.  That’s why adhering a accouter to a cantilevered attic is about a bad idea. Back a accouter is congenital about a cantilevered area of the house, the best accepted way of acknowledging it at the abode is to accept the attic framing headered off, as apparent in the diagram below.

If this is done, aloof be abiding that the ledgerboard is ample abundant to abutment the added weight.  The two photos beneath appearance an archetype of a accouter that was headered off at the patio door, but all of the weight was concentrated to a tiny little allotment of copse that you could hardly alarm a ledgerboard, and was artlessly nailed to the house.  I fabricated a big fetor about this.

The fix for this accurate accouter was to accept posts installed a the house.

*Of course, there are consistently exceptions; sometimes it’s altogether accomplished to attach a accouter to a cantilever.  If addition went out of their way to accomplish this affiliation added defended by installing backward axle hangers at the abode and the framing consisted of all dimensional lumber, it would apparently assignment fine.  As a home inspector, I usually don’t get to see those capacity though.  That’s why I accession apropos over these types of access while administering accouter inspections.
