Code Research

Know the code before you touch the wall.

The Problem

Code violations get caught at inspection — not before. A failed inspection means delays, rework, and a homeowner who’s now questioning everything. Most contractors rely on memory or what they learned years ago. Codes change. Jurisdictions vary.

The Solution

Before any permit gets pulled or scope gets finalized, we research the applicable codes for your trade and jurisdiction. You get a plain-language summary of what applies, what’s changed recently, and what inspectors are actually flagging.
