An as-built survey is completed after construction is finished. It shows the final size, location, and layout of structures and improvements as they were actually built. When a homeowner adds a pool, room, garage, or porch, an as-built survey creates an official record of the completed work and where it sits on the property.

This record is important for permits, inspections, and keeping property records up to date.

What Are As-Built Surveys and Why Do They Matter?

An as-built survey shows the finished condition of a property after construction. It shows where new structures are located, how large they are, and how they relate to property lines and other features on the lot.

Unlike building plans, which show what was intended, an as-built survey shows what was actually built.

This matters because construction does not always follow the original plans exactly. A pool may end up a few feet from its planned location. A room addition may be slightly larger than expected. An as-built survey records the final result and becomes part of the property’s history.

What an As-Built Survey Shows After a Pool Is Finished

After a pool project is complete, an as-built survey shows the exact location of the pool on the property. It measures how far the pool sits from the house, property lines, and other nearby structures.

The survey may also show:

• Pool decking
• Equipment pads
• Fencing
• Drainage improvements

This information is important because many building departments require an as-built survey before closing a pool permit. The survey confirms that the pool meets setback requirements and does not extend into a neighboring property or an easement.

Having the survey ready can help speed up the final inspection and permit close-out.

How As-Built Surveys Document Home Additions

A home addition changes the size and layout of a property. When a new room, garage, or porch is added, the home no longer looks the same as it did before construction.

An as-built survey shows the completed addition and its exact location in relation to the property lines.

This updated record is important because building departments may require it to confirm that the addition meets setback requirements. Lenders and title companies may also request a current survey when a property is sold or refinanced.

An as-built survey gives everyone an accurate picture of the property after the work is complete.

Why Accurate Measurements Matter

Building plans show what a project is supposed to look like before construction begins. An as-built survey shows what the finished project actually looks like.

The two do not always match. Walls may shift slightly, and site conditions can affect the final layout. Changes in grading can also affect how features sit on the land.

Accurate measurements matter because future projects depend on knowing what is already there. If a homeowner later wants to add a fence, widen a driveway, or apply for another permit, updated records can save time and prevent problems.

Clear records give contractors and designers a reliable starting point for future work.

When to Get an As-Built Survey

The best time to get an as-built survey is soon after construction is finished. At that point, the completed structures are easy to measure, and any questions about their final location can still be addressed.

Waiting too long can make some details harder to verify, especially if landscaping or other improvements cover parts of the site.

In many cases, a building department requires an as-built survey before scheduling the final inspection. Contractors, homeowners, and local agencies use the survey to confirm that the project was built according to the approved plans.

Getting the survey done right away helps keep the permit process moving and creates an accurate record before future projects begin.

Frequently Asked Questions

What information is included in an as-built survey?

An as-built survey shows the final size, location, and layout of completed structures and improvements. It may include buildings, pools, decking, fences, and grading changes.

Can as-built surveys be used for both pools and home additions?

Yes. As-built surveys can document many types of completed construction. They can show a new pool, a room addition, a detached garage, or several improvements completed during the same project.

How are as-built surveys different from building plans?

Building plans show how a project was designed before construction began. An as-built survey shows what was actually built after the work was completed. It reflects the final condition of the property.

Who may ask for an as-built survey?

Building departments often require one to close out a permit. Lenders and title companies may also request one when a property with recent improvements is sold or refinanced. Homeowners use them to keep their records current.

Can as-built surveys help with future remodeling projects?

Yes. An as-built survey gives contractors and designers accurate information about existing structures. This helps with planning future work, avoiding conflicts, and making sure new projects meet setback requirements. Starting with accurate records can save time and reduce problems during construction.
