What Is an As-Built Drawing and When Do I Need One in FL?

Key Takeaways

• An as-built drawing documents what was actually built, including field changes, not what was originally proposed. Keep marked-up plans from every trade during construction to avoid a scramble at closeout.

• Don't assume an as-built approves deviations from approved plans. You may still need a formal permit revision, updated plans, or extra inspections, so flag changes during construction.

• Requirements vary by county and city. Request the jurisdiction's written closeout checklist at permit issuance to confirm format, scope, dating, and seal requirements.

• Surveys like final boundary and as-built drainage surveys must be certified by a Florida-licensed professional surveyor and mapper, while revised plans may need an architect or engineer.

• An elevation certificate is a separate flood-related document, not automatically an as-built. Check your flood zone, since some closeout checklists require both.

• Timing matters: a drainage survey submitted before lot stabilization or sod installation may be rejected, so schedule your surveyor with lead time before final inspection.

Picture this: your Florida project is finished, the crew is packing up, and you're ready to call for the final inspection. Then someone at the building department says, "We'll need your as-builts." Suddenly, you're wondering what exactly that means and whether you were supposed to be keeping track of something all along.

Good news: you're not alone, and it's very fixable. If you've ever asked yourself what is an as-built drawing and when do I need one, this guide walks you through it in plain English. We'll cover what these documents are, the different forms they take in Florida permitting, when your local jurisdiction is likely to ask for one, and what to do if your finished work doesn't match your approved plans.

Whether you're a general contractor closing out a job, a solar company wrapping up an install, a realtor chasing a clean closing, or a homeowner who just finished an addition, you'll leave with a clear game plan. Let's dive in.

What Is an As-Built Drawing?

An as-built drawing (also called a record drawing) documents what was actually constructed, rather than what was originally proposed. Think of your approved permit plans as the recipe and the as-built as a photo of the finished dish, including every substitution you made along the way.

Depending on the project, an as-built may show:

• Building dimensions and exact location on the lot
• Utility routes, such as water, sewer, gas, and electrical runs
• Grading and drainage features
• Finished-floor elevations
• Changes made in the field during construction

Construction rarely goes exactly as drawn. A wall shifts six inches, a plumbing line gets rerouted around a beam, or a slab ends up slightly different from the plan. That's normal. The as-built simply captures reality so the building department, utility providers, and future owners have an accurate record.

Not All "As-Builts" Are the Same Thing

Here's where Florida gets a little tricky. In permitting, "as-built" is an umbrella term for several different deliverables, and they are not interchangeable in every jurisdiction. The exact document your project needs depends on the permitting authority, the permit conditions, and the type of work.

That last row matters. A final elevation certificate is a flood-related document, not automatically the same as an as-built drawing. Some Florida closeout checklists require both, depending on your flood zone, project, and local rules.

When Do You Need an As-Built Drawing in Florida?

You may need one whenever a local building department, planning or engineering department, floodplain administrator, utility provider, or permit condition requires verification that the completed work matches the approved plans. Common situations include:

• New construction of homes or commercial buildings
• Additions that change a building's footprint
• Site work involving grading, drainage, or paving changes
• Utility work where routes need to be documented
• Permit closeout before a final inspection or certificate of completion
• Legalizing existing work that was built without proper permits

That last one is especially common. If you're resolving unpermitted work, an as-built is often the starting point because there may be no accurate plans on file at all. Our guide on how to prepare as-builts for an after-the-fact permit in FL covers that scenario step by step.

As-Builts and the Certificate of Occupancy

Many Florida jurisdictions request as-built documentation before a final inspection or certificate of occupancy (CO) or certificate of completion. Requirements vary a lot by county and city, so never assume what worked on your last job applies to the next one.

A real-world example: Charlotte County's published CO guidance for certain new one- and two-family homes calls for a final as-built drainage survey before you request a CO. It specifies that the survey be dated after sod installation or lot stabilization, and it must carry the signature and seal of a Florida-registered surveyor.

Notice how specific that is. The timing, the surveyor credentials, and even the condition of the lot all matter. If you submit a survey too early, you may be asked to redo it. If you're working toward a CO, our Certificate of Occupancy services can help you line up the right paperwork before you call for final.

A Quick Note on Florida Statute 177.073

You might hear that Florida law restricts as-built requirements, and there's a kernel of truth there. Section 177.073 of the Florida Statutes limits local governments from conditioning, delaying, withholding, or denying certain building permits authorized under that section based on submission or approval of as-built or record drawings or similar completion confirmations.

Here's the catch: this is a limited statutory rule. It is not a blanket exemption from project closeout, certificate-of-occupancy requirements, or other applicable rules. Your jurisdiction may still require documentation at a different stage or under a different authority. When in doubt, ask for the written checklist rather than relying on a rule of thumb.

What If the Finished Work Differs From the Approved Plans?

This is one of the most common surprises. Many people assume that handing over an as-built drawing automatically approves any changes. It doesn't.

If construction differs from your approved plans, the building department may require:

1. A formal permit revision
2. Updated plans reflecting the change
3. Additional inspections
4. Approval by the design professional of record

In other words, the as-built documents the change, but the revision process is what legitimizes it. The smartest move is to flag deviations during construction, not at the finish line. Our revisions and resubmittals service exists for exactly this situation, and our plan review coordination keeps reviewer comments from piling up.

How Different Audiences Use As-Builts

General Contractors

For GCs, as-builts are a closeout deliverable. Collecting field changes as you go, with marked-up plans from each trade, saves a scramble later. Missing documentation is one of the most avoidable reasons a final inspection stalls.

Solar Companies

Solar installs can drift from the permitted design: panel counts, array layout, or conduit routing change on the roof. A clean record of what was installed helps with inspections and utility interconnection. See our resources for solar contractors for faster approvals.

Realtors and Property Buyers

If an inspection or title search reveals an addition or enclosure with no matching plans, an as-built is often the first document needed to bring it into compliance before closing. Learn more about realtor closing support.

Homeowners and Residential Property Owners

If you've finished a remodel, addition, or pool and the building department is asking for documentation, an as-built keeps your permit from lingering open, which can create headaches when you refinance or sell. Our homeowner resources are a friendly place to start.

Who Can Prepare an As-Built in Florida?

The answer depends on the type of document. Some must be prepared and certified by a Florida-licensed professional surveyor and mapper, such as boundary surveys, drainage surveys, and elevation certificates. Design-plan revisions may require a Florida-licensed architect or engineer, depending on the work and any applicable exemptions.

This is where having an integrated team pays off. At 1 Contractor Solutions, drafting and engineering are in house, and our engineer signs and seals the work, so you aren't waiting on an outside consultant to call someone back. You can explore our as-built drawings service and our engineering services to see how it fits together.

How to Find Out Exactly What Your Jurisdiction Requires

Because there is no reliable statewide count of how many Florida permits require as-builts, requirements are jurisdiction- and project-specific. Here's a simple process to avoid surprises:

1. Identify the right jurisdiction. Near city lines, the authority isn't always obvious. Our building department lookup tool can help.
2. Request the closeout checklist early. Ask for it at permit issuance, not at final inspection.
3. Confirm format, scope, date, and credentials. Does the document need a seal? Must it be dated after sod?
4. Check your flood zone. This determines whether an elevation certificate joins the list.
5. Track field changes from day one. Mark deviations as they happen.
6. Schedule the surveyor or drafter before you need it. Lead times can slip your final inspection date.

Local requirements differ widely. For instance, projects in Hillsborough County, Miami-Dade County, and Charlotte County can each have their own expectations for closeout paperwork.

What a Good As-Built Should Include

While the exact content depends on the deliverable, solid as-builts generally share these traits:

• A clear title block with the project address and permit number
• Accurate dimensions and locations of the completed work
• Notes identifying any deviations from the approved plans
• A date reflecting when the conditions were documented
• Required signatures and seals from the appropriate Florida-licensed professional
• Legible formatting that matches the jurisdiction's submission requirements

Skipping any of these can lead to a rejection and another round of review, which is exactly the kind of delay you were hoping to avoid.

Common Mistakes to Avoid

• Assuming an as-built approves changes. It doesn't replace a permit revision.
• Ordering too early. A survey dated before lot stabilization may be rejected where timing is specified.
• Mixing up document types. A survey, an elevation certificate, and revised plans are different deliverables.
• Waiting until final inspection. Discovering requirements at the last minute can delay your CO.
• Hiring the wrong credential. Some documents require a surveyor; others require an engineer or architect.
