As-built drawings show what's there now. They are the first step for a remodel or addition, or for legalizing unpermitted work.
Before a remodel or addition; for already-built permits; when your records don't match the house; or for your own records.
Site visit and measure; draw floor plans, plus elevations and site plan if needed; then next steps for permitting. Unpermitted work may need opened walls or an engineer letter, coordinated with Dow Engineering PLLC when structural. Talk to a Sherpa.
