We’re having a backyard leveled on a canyon slope, with pavers planned above a retaining wall that’s about four or five feet high at its tallest. The bottom row was laid directly on soil, and the wall drainage and backfill don’t match what I expected. The contractor is coming to look at it, but I’m not sure how to judge the work or what to ask for before the area gets finished.
Should I stop work until someone checks this retaining wall?

I’d pause the work that would cover or load the wall, especially the pavers, until it’s been checked. Ask an independent structural or geotechnical engineer to inspect the actual site and the work so far. Photos and a verbal assurance from the contractor aren’t a substitute for checking the base, drainage, wall design, and slope conditions.

Keep the conversation specific and in writing. Ask for the wall’s design details, how the base was prepared and compacted, what drainage path is provided behind it, and whether the planned backfill and any reinforcement match the design. Solid gutter drains and wall drainage may serve different purposes, so ask how water behind the wall is supposed to get out rather than assuming one system covers both.
Also check with your local building department about permits and inspections. Requirements vary by location and conditions, so the wall’s height alone doesn’t settle that question.

Don’t get pulled into arguing over whether a little mortar or a particular kind of gravel makes it fine. The whole setup matters, including the slope, foundation, drainage, wall system, and the fill above it. A qualified independent person should be able to explain what they observed and whether the finished design is appropriate for this site.
I’d take dated photos now, keep the contract and messages, and avoid approving concealed work until you’ve got an independent assessment. If the contractor resists a reasonable inspection, ask the local building department what options apply.

That makes sense. I’ll ask for the design and drainage plan, and arrange an independent assessment before the pavers go down.

Would you ask them to dig out the base before the inspection, or wait for the engineer to say what needs to be exposed?

I’d leave it as-is until the inspector has seen it. They can tell you what needs to be uncovered, and you’ll have a clearer record of the existing work.
