Self Supported Mid-Landings in Houses<br />
Issue:<br />
More and more stairs manufacturers are yielding to consumer’s desire for open<br />
concept design. Manufactured self supported mid-landings a.k.a. “cranked landings”<br />
are constructed as one single stairs structure without intermediate post supports.<br />
This is beyond a Part 9 design.<br />
Decision:<br />
This design must have P.Eng.’s approval. The stamped drawings may be submitted<br />
for Master Footprint or to the Inspector on site.<br />
Implementation: At the time of the framing inspection, inspector will review of the engineer’s stamped<br />
drawings to verify the installation for each project.<br />

Garage Floor Drain<br />
Issue:<br />
Different approaches to the inspection of the design and installation of the plumbing<br />
services in an attached garage’s floor drain needs a standard approach within the<br />
Branch.<br />
Decision:<br />
A residential garage floor drain inside a heated or unheated attached garage is<br />
permitted where the garage slab maintains an overall slope to direct the flow of<br />
liquids from the house end wall towards the garage overhead doors to the exterior.<br />
On serviced and unserviced lots, the preferred method is to direct the drainage to<br />
the house’s sanitary drainages system. Where septic capacity cannot be<br />
demonstrated dry well or surface drainage methods are acceptable.<br />
Implementation: The inspection shall consist of the following elements:<br />
garage floor slab’s overall downward slope to the exterior<br />
min. 3” ø drain pipe, trap, trap seal primer, cleanouts, and venting to comply<br />
with the OBC<br />
protection from freezing<br />
sand and grit interceptor must be accessible and serviceable<br />
