Orange County FL Inspection Type Codes — What Each Inspection Means
Orange County uses numerical inspection codes for building, electrical, mechanical, plumbing and gas permits. This guide translates the codes into plain English, explains when each inspection is typically requested, and gives practical tips for avoiding covered-work and permit-closeout problems.
Important for missed inspections: Do not assume an engineer letter automatically replaces a County inspection. Orange County’s current Private Provider Manual states that covered work generally must be exposed unless Orange County authorizes an exception, and engineer letters are not accepted in place of required inspections unless specifically authorized by the County. If your work is already concealed, first confirm the required path with the inspector or permit reviewer.
Building Inspection Codes
Building inspections generally follow the construction sequence from site work and foundations through framing, insulation, roofing and final occupancy/permit closeout. The exact inspections shown on your permit control.
| Code | Inspection | When it is commonly needed | Practical tip | Engineer-letter relevance |
|---|---|---|---|---|
| 100 | Site | Early site inspection where setbacks, layout, access, grading or other site conditions must be checked before construction advances. | Have permit plans and site layout available; verify property lines/setbacks before irreversible work. | Usually low |
| 110 | Footing / Foundation | Before concrete is placed, while excavations, reinforcing steel, forms and bearing conditions are visible. | Do not pour until the required inspection is approved. If already poured, documentation and County direction become critical. | Common missed-inspection issue |
| 115 | Stemwall | For masonry or concrete stemwall construction, generally before the work is concealed or backfilled. | Keep reinforcing, cells, dowels and connections visible for inspection. | Possible |
| 120 | Slab | Before slab placement, typically after base preparation, vapor barrier, reinforcement and embedded items are ready. | Photograph reinforcement, vapor barrier, sleeves and dimensions before the pour. | Common |
| 121 | Sidewalk & Driveway | For permitted flatwork, driveway approaches, accessibility-related work or site improvements. | Confirm slope, thickness, reinforcement and right-of-way requirements before placement. | Case specific |
| 130 | Footing / Slab (Monolithic) | For monolithic slab-on-grade foundations where the thickened edge/footing and slab are poured together. | This is a high-value inspection to photograph thoroughly before concrete. | Common |
| 135 | Flood Plain Certification | When a project is in a regulated flood hazard area and elevation/floodplain compliance must be documented. | Coordinate survey/elevation documentation early; flood approvals can hold up final closeout. | Possible specialized certification |

| 270 | Landscaping Final (Zoning) | Near project closeout where required landscaping/zoning conditions must be verified. | Check approved landscape/zoning plans, not only building plans. | Usually not an engineer letter |
| 279 | Roof Flashing (Other) | For flashing details that must be seen before roofing/finish work conceals them. | Photograph underlayment, flashings and penetrations in-progress. | Possible roof affidavit issue |
| 280 | Roof Final (Re-Roof & New Roof) | At completion of new roofing or reroofing work. | Keep product approvals, permit documents and any required in-progress photos available. | Common permit-closeout issue |
| 281 | Re-Roof / In-Progress | During reroofing while underlayment, attachment or other required concealed components are still visible. | Do not finish the roof before this inspection if it is listed on the permit. | Very common missed inspection |
| 290 | Final | At project completion after required trade and prerequisite inspections are approved. | Resolve outstanding corrections and paperwork before scheduling. | Closeout related |

What if the Orange County inspection was missed?
If the work is still exposed, the simplest path is normally to schedule the required County inspection before covering it. If the work has already been covered, concealed or completed, the next step depends on the permit, the inspection that was missed and the County’s direction.
Orange County’s Private Provider Manual specifically states that covered work must be exposed for inspection unless Orange County grants an exemption, and that affidavits, photographs and engineer letters are not automatically accepted in place of required inspections. An engineer letter may be useful when the County or Building Official specifically authorizes that approach.
Best records to preserve: permit number, approved plans, inspection history/corrections, contractor invoices, product approvals, in-progress photos, dimensions, material labels, test reports and clear photos of any areas still accessible. Better contemporaneous documentation usually makes an after-the-fact engineering evaluation more practical.
Orange County Inspection FAQ
Where do I find which inspections my permit actually requires?
Use the inspection requirements and history associated with your specific permit in Orange County’s Fast Track system. The general code list is a reference; not every permit requires every inspection.
Can I cover work after I take photos?
Do not rely on photos as permission to cover required work. If an inspection is required, obtain the required approval before concealment unless Orange County gives project-specific direction otherwise.
Can a Florida PE write a letter for a missed framing, slab, rough-in or roof inspection?
A PE can evaluate and document appropriate engineering issues within the engineer’s scope, but whether Orange County accepts a letter in place of a missed County inspection is an AHJ decision. Confirm the requested remedy with the inspector or plan reviewer first.
What are the most common inspections that become difficult after the work is covered?
Foundations/footings, monolithic slabs, reinforcing steel, lintels/tie beams, framing, insulation, lath, roof in-progress work, underground electrical/plumbing, rough-in electrical/plumbing/mechanical and concrete-encased bonding are all much easier to verify before concealment.
