A Code Case Is Won on Specifics, Not Impressions
A building code expert witness determines whether the built conditions in a property met the code that actually governed the work, then explains those findings to attorneys, insurers, and the court. In Chicago and Cook County, that means fixing the correct code edition and amendments, examining the records and the as-built conditions, and tying every opinion to a specific provision, listing, or standard.
Paul Gaston, a licensed City of Chicago General Contractor with more than 30 years in the field, approaches each matter the way a contractor builds to code in the first place. He works the same way whether he is retained by the plaintiff or the defense, because the method, and not the client, drives the opinion.
What the Review Covers
A thorough building-code review reaches across trades and documents. Common items include:
- The governing code edition, amendments, and effective date
- Occupancy classification and construction type
- Permits, approved drawings, and inspection records
- Flooring, handrails, guards, and stair geometry
- Means of egress elements and continuity
- Fire-rated assemblies and opening protectives as installed
- Differences between the approved documents and the as-built result
The strongest code opinions are the ones a jury can check for themselves, tied to a provision, a listing, and a photograph of the actual condition.
Why the Governing Code Comes First
Before any compliance opinion can be trusted, one question has to be answered: which code governed the work. Applying the current code to older, permitted work, or ignoring a local amendment, is one of the fastest ways an opinion is challenged. Establishing the governing edition first keeps the analysis anchored to the requirement that truly applied.
From there, the expert separates code-compliance questions that fall within a licensed contractor's qualifications from engineering-design questions that belong to a professional engineer or architect. Staying in that lane is both the honest position and the more durable one under cross-examination.
How Paul Gaston Helps Resolve the Dispute
Paul provides documented, code-anchored analysis and testimony for plaintiff and defense counsel across Chicago and Cook County. His work includes records review, site inspection, written reports, rebuttal, and deposition, arbitration, and trial testimony, each tied to the code and the conditions at issue.
For attorneys and insurers, the value is clarity: a clear account of what the code required and what was built, in language a court can follow, that supports a claim or a defense through settlement or trial.
Frequently Asked Questions
At what stage of a case should an attorney retain a building code expert?
Earlier is usually better. Bringing in a code expert before inspections, discovery deadlines, and disclosures lets the expert help preserve evidence, frame document requests, and evaluate conditions before they are repaired or altered. Late retention still works, but it can limit access to original conditions.
Can a building code expert help even when liability seems obvious?
Yes. Even where a violation looks clear, an expert establishes the governing code, documents the condition, and connects it to the specific provision, which is what makes the point admissible and persuasive. On the defense side, the same rigor can narrow or reframe what the condition actually shows.
What is the difference between a consulting code expert and a testifying one?
A consulting expert may advise counsel behind the scenes, while a testifying expert issues opinions in a report and defends them at deposition or trial. Paul can serve in either role, and the analysis is built from the start to withstand disclosure and cross-examination.
