Direct answer
The short version
Before you pay for design or builder work, confirm the address, parcel, likely path, top blockers, evidence gaps, and next real step. If those are unclear, the project is not ready for expensive decisions.

Why the label matters
The checklist turns official process and property evidence into a homeowner decision sequence. It should not be presented as permit approval.
FAQ
Common follow-ups
What is the first expensive mistake?
Paying for a path that was never realistic for the lot. Start with the address and blockers.
What should be verified before deeper design?
Parcel identity, zoning source, lot geometry, likely path, and any Needs review items that could change fit or cost.
