As-Built Surveys & Existing-Conditions Mapping

Document exactly what was built and where. We measure existing structures, improvements, and utilities into accurate as-built records for permits, closings, and design.

Tell us what the city, county, architect, or engineer requested — we'll help confirm the right survey for your project. Call now to discuss it.

What is As-Built Survey?

An as-built survey documents the real-world location and dimensions of structures, improvements, and utilities as they currently exist. It confirms that construction matches the approved plans, creates a record drawing for owners and engineers, and supports commercial transactions and permitting. Where a project drifts from plan, the as-built is the accurate record everyone relies on.

Frequently asked questions

What is an as-built survey?

It is a measured survey of what currently exists on a site — structures, improvements, and utilities — documenting their actual location and dimensions, often compared against the approved design plans.

How is it different from construction staking?

Construction staking marks where to build before and during construction. An as-built survey records where things actually ended up after construction, creating the official record drawing.

Do I need an as-built for a commercial transaction?

Buyers, lenders, and tenants often want documented existing conditions. We provide as-built and site surveys, and full ALTA/NSPS surveys, depending on what the transaction requires.

How much does an as-built survey cost?

It depends on the size and complexity of the structures and site features to be documented. Request a free estimate and we will scope it.

Licensed Surveyor Oversight

Survey work is completed by, or under the responsible charge of, California-licensed Professional Land Surveyors. When a stamped survey is required, the final deliverable will identify the responsible licensee for that project.
