What Is an As-Built Survey?
An as-built survey — also called a post-construction survey or record survey — documents the actual location, dimensions, and elevations of completed improvements after construction is finished. It answers a critical question: does what was built match what was approved?
The survey shows the finished structure's position relative to property lines, easements, setbacks, and other site features. If anything shifted during construction — a building placed a few inches off, a retaining wall that's slightly different from the plans, or finished grades that don't match the design — the as-built survey reveals it.
In San Antonio, as-built surveys are commonly required by the City permitting office to close out building permits, by lenders for construction draw releases, and by developers for subdivision compliance documentation. They're the final survey in the construction lifecycle — and the one that proves the project was built correctly.
An as-built survey from Alliance documents:
Completed structures — building footprints, additions, garages, retaining walls, pools, and any other permanent improvements measured and located to scale.
Distances to property lines — how far each improvement sits from each boundary, verifying setback compliance.
Finished grades and elevations — actual grade elevations at building corners, pads, and drainage points compared to design plans.
Utility connections — as-built locations of water, sewer, storm, and electrical connections where visible or as provided by the contractor.
Paving and hardscape — driveways, parking areas, sidewalks, and curbing as constructed.
Compliance verification — notation of any deviations from the approved plans, easement conflicts, or setback encroachments.
Where the As-Built Fits in Your Project
The as-built survey is the final survey in a multi-step construction sequence. Using the same surveyor from staking through as-built ensures consistency and eliminates discrepancies between phases.

Common Reasons for an As-Built Survey
Building Permit Closeout
The City of San Antonio may require an as-built survey to verify setback compliance and improvement locations before closing out a building permit and issuing a certificate of occupancy.
Lender Draw Requests
Construction lenders often require an as-built survey at completion to verify that the finished project matches the approved plans before releasing the final draw or converting to permanent financing.
Subdivision Compliance
Developers building out subdivisions need as-built documentation showing that infrastructure (roads, utilities, drainage) was constructed per the approved plat and civil plans.
Custom Home Completion
After your custom home is finished, an as-built confirms the house, garage, driveway, and any other improvements sit within the correct setbacks and don't encroach on easements.
Insurance Documentation
Some insurance carriers require as-built surveys to verify building dimensions, finished floor elevations, and proximity to flood zones or property lines for underwriting purposes.
HOA & Deed Restriction Compliance
Some HOAs require as-built documentation to verify that completed improvements comply with architectural guidelines, setback rules, and deed restrictions.
