Crawlspace Joists Cut for Plumbing, an Unfooted Pier, and an Agent Asking for 'Fine'
During a crawlspace inspection of a 1958 ranch with a 24-inch access hatch, you find a 2x8 floor joist spanning 12 feet that has been notched 1 1/2 inches deep across its bottom edge roughly mid-span to clear a 3/4-inch copper heating pipe. Two joists away, a previous owner cut a 3-inch hole through the center of another 2x8 for a drain line. The subfloor above shows a 1/4-inch dip over about 4 feet, and a newer 4x4 post in the center of the crawlspace sits on a 12-inch concrete block laid flat on bare soil, with no footing visible. The seller's disclosure states a 'beam was reinforced in 2019' but no permit record exists. The buyer's agent asks you to say the floor is 'fine' so financing can close Friday.
1. Which of these conditions actually exceed the IRC notching and boring limits, and how do you turn the numbers into report language on a 1958 house?

What the numbers say. For a nominal 2x8 (actual depth 7 1/4 in.), IRC R502.8.1 caps a top or bottom edge notch at one-sixth of the depth - roughly 1 3/16 in. - and prohibits notching in the middle third of the span. This notch is 1 1/2 in. deep and near mid-span, so it fails on two counts, not marginally. The same section caps bored holes at one-third of the depth (about 2 3/8 in.) and keeps them out of the middle third; a 3-in. hole through the center of the member exceeds both.
Why that is not the whole answer. The IRC governs new construction; a 1958 house was framed under different rules, and an inspector who writes 'code violation' on a 65-year-old joist invites an argument he cannot win. The reportable issue is performance: the notch, the hole, and the 1/4-in. dip over 4 ft sit in the same area, which is the difference between three trivia items and one pattern.
Report language. 'Two floor joists in the crawlspace have been modified for plumbing. One is notched about 1 1/2 in. on the bottom edge near mid-span; the other has a 3-in. hole through its center. Both exceed the limits in current model codes for a member of this size, and the floor above is out of level about 1/4 in. over 4 ft in the same area. Visual inspection cannot determine the remaining capacity of these joists. Recommend evaluation and repair design by a licensed structural engineer or a contractor working under an engineer's direction.'
2. The buyer's agent asks you to write that the floor is fine. What can you honestly say, and how do you handle the request?

The line. I describe conditions; I do not certify structural adequacy. 'The floor is fine' is an engineering opinion, and more importantly it is a conclusion the visual evidence does not support. The one honest thing I can write is a scope statement: 'No evidence of active movement - fresh drywall cracking, pulled fasteners, doors out of square - was observed at the time of inspection.' That is a statement about what I saw, not a prediction about capacity.
Why not soften it. The report is the client's record of the condition at the time of the inspection. If those joists deflect later and a tile floor cracks, the report that says 'fine' is the document read aloud in a deposition, and a Friday closing deadline is not a defense.
How to handle the request. Decline once, plainly, and offer the accurate alternative: the report will describe the notches, the hole, the dip, and the missing footing, and will recommend engineer review. That is the fastest path to a buyer who can make an informed decision by Friday, because the buyer can then negotiate a credit or a repair rather than discovering the problem after closing. Document the request with date and time. Keep the report to your client; the agent is a third party unless that relationship was disclosed in writing before the inspection.
3. How do you evaluate and report the post bearing on a block on bare soil, and what do you do with the unpermitted 2019 'reinforcement'?
Read the worked answer
What is visible. The post bears on a single 12-in. concrete block laid flat on bare soil. There is no visible footing, no post base, and no positive connection between post and anything below it. Current practice requires a footing sized for the load and the soil, placed below frost depth or on undisturbed grade as applicable, with a mechanical connection between the post and the footing. A flat block on soil provides bearing but essentially no resistance to settlement, frost heave, or lateral displacement.
What I can and cannot conclude. From a 24-in. hatch I can see bearing, alignment, shim stacks, and rot at the base. I cannot see soil bearing capacity, frost depth, or whether a footing exists beneath the block. So the report says what is visible and what is not: 'Center support post appears to bear on a single concrete block placed on the crawlspace soil. No footing or post base was visible. Recommend evaluation by a licensed structural engineer or qualified foundation contractor; the adequacy of this support cannot be determined visually.'
The permit angle. The disclosure says a beam was 'reinforced' in 2019 with nothing on record at the building department. I cannot verify undocumented work and should not adopt the seller's characterization. Recommend the buyer obtain the contractor's written scope, any engineer's letter associated with the work, and the permit history. If the reinforcement consisted of adding this post, that changes the picture: the post may be the repair, and its footing is then the thing being evaluated.
