What is an as-built floor plan?

An as-built floor plan is a drawing that shows the existing conditions of a space exactly as it is today. It documents wall locations, room dimensions, doors, windows, and key features so designers, contractors, and owners can plan renovations or construction with confidence.

Why are as-built drawings important before starting a renovation?

Starting design or construction without accurate as-built drawings often leads to surprises, design revisions, and costly changes during construction. As-builts provide a reliable foundation so everyone is working from the same, accurate information from day one.

How do you create your as-built floor plans?

We begin with a site visit where we carefully measure and document the existing space. That information is then translated into precise CAD drawings, followed by a quality review to ensure accuracy before delivery.

Who typically needs as-built floor plans?

As-built floor plans are commonly used by real estate investors, architects, designers, and general contractors. They’re especially helpful when planning remodels, additions, ADUs, or preparing documentation for permits.

Can as-built floor plans be used for permits and design work?

Yes. As-built floor plans are often used as the starting point for permit sets, renovation design, and construction planning. While final permit requirements vary by jurisdiction, accurate as-builts make the entire process smoother and more efficient.
