1When splicing a double top plate on a wood-framed remodel wall under IRC 2018, what is the minimum lap (offset) required between end joints in the two plate members?
A.12 inches
B.16 inches
C.24 inches
D.48 inches
Explanation: IRC 2018 Table R602.3(1) requires double top-plate end joints to be offset at least 24 inches, with face-nailing on each side of the joint (8-16d common, or 12-16d box or equivalent). The offset keeps the plate line continuous so gravity and lateral loads transfer around the splice. A shorter lap leaves a weak section in both plates at nearly the same station.
2A plumber wants to notch the top of a solid-sawn 2x10 floor joist to run a drain. Under IRC 2018 R502.8.1, where is that notch prohibited?
A.In the middle one-third of the span
B.Anywhere within 12 inches of a bearing
C.In the outer one-third of the span only
D.Only at the exact midspan point
Explanation: IRC 2018 R502.8.1 prohibits notches in the middle one-third of the span of solid-sawn joists, rafters, and beams. That zone carries the highest bending stress. Allowed notches are limited to one-sixth of the member depth and one-third of the depth in length, and end notches are limited to one-fourth of the depth.
3A 2x10 solid-sawn floor joist measures 9-1/4 inches deep. What is the largest hole diameter IRC 2018 R502.8.1 allows, and how far must the hole stay from the top or bottom edge?
A.3 inches diameter, 2 inches from either edge
B.2 inches diameter, 1 inch from either edge
C.4-5/8 inches diameter, 2 inches from either edge
D.1-1/2 inches diameter, 3 inches from either edge
Explanation: Bored holes may not exceed one-third of the joist depth and must stay at least 2 inches from the top, the bottom, and any other hole or notch. One-third of 9-1/4 inches is about 3.08 inches, so a 3-inch hole is the largest standard bit that complies. A 4-5/8-inch hole is half the depth and is over the limit.
4What is the minimum bearing length IRC 2018 requires where a floor joist bears on a wood plate or on masonry?
A.1-1/2 inches on wood or metal and 3 inches on masonry or concrete
B.3/4 inch on wood and 1-1/2 inches on masonry
C.3 inches on wood and 4 inches on masonry
D.The full width of the joist on any support
Explanation: IRC 2018 R502.6 requires joists, beams, and girders to bear at least 1-1/2 inches on wood or metal and 3 inches on masonry or concrete. Those lengths keep the end-grain bearing stress within allowable values. Joist hangers that provide equivalent bearing are an accepted alternative.
5A 2x4 bearing-wall stud is 3-1/2 inches deep. What is the deepest notch IRC 2018 R602.6 allows in that stud?
A.7/8 inch (25 percent of the stud depth)
B.1-3/8 inches (40 percent of the stud depth)
C.1-3/4 inches (50 percent of the stud depth)
D.2-1/8 inches (60 percent of the stud depth)
Explanation: R602.6 limits notches in exterior-wall and bearing-partition studs to 25 percent of the stud depth. Twenty-five percent of 3-1/2 inches is 7/8 inch. Nonbearing partition studs may be notched up to 40 percent. Holes follow a different rule (up to 60 percent, with doubling when a bearing stud exceeds 40 percent).
6An electrician bores a 1-3/4-inch hole through a single 2x4 (3-1/2-inch) stud in an exterior bearing wall. The hole edge is 7/8 inch from the stud edge and is not in a notched section. What does IRC 2018 R602.6 require?
A.The stud must be doubled, and not more than two successive doubled studs may be bored over 40 percent
B.Nothing further — any hole up to 60 percent of the stud is always allowed in a single stud
C.A 16-gage steel stud shoe is mandatory on every bored bearing stud
D.The hole must be filled with epoxy before the wall is closed
Explanation: 1-3/4 inches is 50 percent of 3-1/2 inches, which is over 40 percent and not over 60 percent. For exterior and bearing studs, R602.6 requires those studs to be doubled, with no more than two successive doubled studs bored that large. The hole must also stay at least 5/8 inch from the stud edge and out of a notched cross-section. Approved stud shoes are an alternative, not a universal requirement.
7A plumber notches more than half the width of a load-bearing double top plate for a drain. The wall is not sheathed with wood structural panels on the notched side. What repair does IRC 2018 R602.6.1 require?
A.Install a 16-gage by 1-1/2-inch galvanized metal tie extending at least 6 inches past each side, with not less than eight 10d nails each side
B.Sister a second 2x4 flat across the notch with two 8d nails
C.Fill the notch with construction adhesive and a wood plug
D.Add blocking between the nearest two studs and continue
Explanation: R602.6.1 requires a galvanized metal tie not less than 0.054 inch thick (16 gage) and 1-1/2 inches wide when a load-bearing or exterior top plate is cut more than 50 percent of its width. The tie must extend at least 6 inches past the opening on each side and receive at least eight 10d (0.148-inch) nails 1-1/2 inches long on each side. Wood structural panel sheathing covering the entire notched side is the listed exception.
8In a crawl space, when must solid-sawn floor joists be naturally durable or preservative-treated under IRC 2018 R317.1?
A.When they are closer than 18 inches to exposed ground
B.When they are closer than 12 inches to exposed ground
C.When they are closer than 8 inches to exposed ground
D.Only when they actually touch the soil
Explanation: R317.1 requires decay-resistant or preservative-treated wood for joists (or the bottom of a wood structural floor) closer than 18 inches to exposed ground in a crawl space, and for girders closer than 12 inches. Columns have an 8-inch clearance trigger. Contact with soil is a separate, stricter ground-contact treatment rule.
9After a field cut on preservative-treated sill plate, what does IRC 2018 R317.1.1 require?
A.Treat field-cut ends, notches, and drilled holes in accordance with AWPA M4
B.Paint the cut with interior latex to seal the end grain
C.No further treatment is required once the piece left the treating plant
D.Wrap the cut end in polyethylene and tape it
Explanation: R317.1.1 requires field treatment of cut ends, notches, and bored holes in preservative-treated wood in accordance with AWPA M4. Plant treatment does not fully penetrate most dimension lumber, so a fresh cut exposes untreated core. Copper-naphthenate or another AWPA M4 field preservative is the usual product.
10During a kitchen remodel a plumber wants to cut a hole through an I-joist web for a 3-inch drain. What does IRC 2018 R502.8.2 allow?
A.No cuts, notches, or holes except where the manufacturer permits them or a registered design professional designs them
B.Any hole that stays 2 inches from the flanges, same as sawn lumber
C.Holes up to one-third of the I-joist depth anywhere in the web
D.A hole of any size if it is filled with expanding foam
Explanation: R502.8.2 prohibits cuts, notches, and holes in I-joists, trusses, SCL, glulam, and CLT unless the manufacturer’s recommendations allow the alteration or a registered design professional accounts for it. Sawn-lumber one-third-depth and 2-inch-edge rules do not apply to engineered members. Most I-joist makers publish specific knock-out zones; leaving those zones is not a substitute for reading the listed hole chart.
