The city wants a "final survey" or "as-built" after my new garage is finished. What is that?

An as-built survey (also called a final survey) shows what was actually built and where, after construction is done [1].

It typically shows:

  • the finished building's location and distances to the lines,
  • driveways, patios and other improvements,
  • sometimes elevations, drainage features or utilities, depending on local requirements.

When it's needed:

  • Permit closeout: to prove the building meets setbacks and the approved plan.
  • Financing or sale of new construction.
  • Engineering projects: utilities and site work, where as-builts record what went into the ground [2].

Ask the permit office exactly what it requires, then share that list with your surveyor. If the building was staked by a surveyor before construction, the as-built is usually quick and smooth [3].
