10 Mistakes I Made as a Homebuilder That now Make me Better as a Construction Lawyer

After years building custom homes and running excavation, utilities, and sitework operations, I’ve made most of the mistakes you can make in construction. At the time, they were expensive lessons. Looking back, they now shape how I advise clients every day as a construction lawyer.

1. Starting work without fully locked scope. Assuming “we’ll figure it out in the field” works—until it doesn’t. Vague scope turns into change orders, disputes, and strained relationships.

2. Underestimating the importance of written change orders. Verbal approvals are fine in theory, but they collapse the moment money gets tight or memories differ.

3. Trusting incomplete engineering or site data. Bad design assumptions don’t show up in spreadsheets—they show up in field changes, delays, and claims.

4. Treating scheduling as flexible instead of contractual. If the schedule isn’t enforced, it doesn’t exist. Coordination failures compound fast across trades.

5. Not documenting field conditions in real time. If it isn’t documented contemporaneously, it’s often treated later as if it didn’t happen.

6. Assuming insurance will “handle it”. Coverage gaps, exclusions, and notice requirements matter more than most builders realize—until a claim is denied.

7. Overextending cash flow on optimism. Even good projects can fail financially if draw timing, retainage, and pay apps aren’t managed tightly.

8. Not aligning subcontractor contracts with owner obligations. If your subcontracts don’t mirror your prime contract, you inherit risk you thought you passed downstream.

9. Treating permitting and inspections as administrative instead of strategic. Late permits or inspection failures can quietly control the entire critical path.

10. Relying on handshake understandings instead of enforceable terms. Construction runs on relationships—but disputes are decided on documents.

What changed for me is simple: every one of these “mistakes” eventually became a legal issue I now see from the other side of the table. Claims that could have been avoided, disputes that could have been contained, and risks that could have been allocated more clearly from day one.

The best construction law advice is rarely abstract—it’s operational. It comes from having lived through the jobsite realities that later end up in a courtroom, arbitration, or negotiation.

If you’re building or contracting in today’s environment, the legal risk usually isn’t hidden in the big issues. It’s buried in the day-to-day decisions that feel routine at the time.
