Collier County Growth Management: Building Permit Submittals Explained

How Collier County's Growth Management Department (GMD) takes permit applications, what a new one- or two-family home submittal needs, and how the county's FEMA 50% worksheet works.

Quick Answer

Short answer: a new one- or two-family home in Collier County is submitted online through the GMD Public Portal with construction plans, a site plan and the product approval index. Depending on the lot you may also need a stormwater plan, a vegetation removal affidavit, septic approval, a preservation review form or the FEMA 50% packet.

Collier County's Growth Management Department reviews building permits for unincorporated Collier County, from Golden Gate Estates to Immokalee. The City of Naples and the City of Marco Island run their own building departments. Collier is a fully electronic shop: contractors, design professionals and agents must submit through the GMD Public Portal. The paper exception is for property owners who qualify as owner-builders, and even they sign the owner-builder application in person, notarized by Growth Management staff.

What does Collier County require for a new 1 & 2 family home?

Collier's PRFH application requirements list the core package as construction plans, a site plan and the product approval index.

On top of that, the county lists conditional items that depend on the lot and the scope. Those conditional items are where most first-time submittals get rejected, so it pays to sort them out before the drawings are finished.

When is a stormwater plan required in Collier County?

Collier requires a storm water plan on lots with one- and two-family dwellings, with two exceptions.

Lots in the Rural Agricultural (A) zoning district outside the Immokalee Urban Area Overlay and outside the coastal urban designated area on the Future Land Use Map are exempt. So are lots that already received a Surface Water Management or Environmental Resource Protection permit from the South Florida Water Management District. Everyone else should plan for grading and drainage on the site plan.

What are the vegetation and preservation rules for building lots?

If the lot is one acre or larger, Collier asks for a Vegetation Removal Affidavit.

One acre of vegetation may be removed after the single-family permit is issued, and clearing more than one acre needs a separate Vegetation Removal Permit. In the Rural Fringe Mixed Use District the county also asks for a Preservation Review Form. Estates lots often hit both, and they shape where the house, drive and septic field can go.

How does Collier County apply the FEMA 50% rule?

For work on a building in a Special Flood Hazard Area, Collier asks for its Substantial Improvement and Substantial Damage affidavit packet and the 50% Cost Estimate Worksheet.

The county's packet is explicit about incremental repairs: they are not allowed. All repairs, even ones done at different times or under different permits, must be listed and calculated together on the worksheet, and the worksheet must include all open permits.

For market value, Collier uses the Improved Value of the structure from the Collier County Property Appraiser, which excludes land.

Staff can administratively add 20% to that Improved Value to get a closer market figure. If you disagree, you can hire a Florida-licensed appraiser for a comparable appraisal. If the work is substantial, the building must meet flood-resistant construction standards, including elevating to base flood elevation plus one foot.

There is a Collier-specific caveat to that add-it-all-up rule.

Section 163.31795, Florida Statutes (s. 2, ch. 2025-190), now bars an NFIP community from enforcing a substantial-improvement ordinance that uses a cumulative period. Listing every repair in the current scope and every open permit on the same building on the worksheet is still what the packet asks. If staff also want closed permits from earlier years added to the total, ask the Floodplain Management Section which rule they are applying before you cut the scope. Confirm the current 20% adjustment with the Floodplain Management Section (239-252-2942) before you rely on it.

Private providers, owner-builders and septic sites

Collier accepts a Private Provider Package when a private provider performs plan review or inspections.

Owner-builders must supervise on site any work not done by licensed contractors. Where the site uses a septic field, a health or environmental septic application is part of the package. Each of these changes who signs what, so we confirm them at kickoff.

Collier County permit questions

Where will Collier County stamp my approved plans?

In the upper right corner. Collier's e-permitting page says approved documents are stamped there at the end of review and asks designers to keep that corner blank so no information is lost. Uploads should also be under 72MB each, and plans must be drawn to scale.

When does a Collier County site plan need to be certified?

Collier's 1 & 2 family page says the site plan may need certification when new impervious area exceeds 400 square feet. A certified plan must be no older than six months and signed and sealed by a Florida surveyor and mapper, architect or engineer.

How far must a new Collier County home be from a septic system?

At least 5 feet, per Rule 62-6.005(2), Florida Administrative Code. Collier asks the site plan to show that distance when the lot is on septic.

Can I find an existing elevation certificate for a Collier County building?

Yes. The county's floodplain page links a DFIRM map with elevation certificates that you can search by address, and the Floodplain Management Section (239-252-2942, FloodInfoRequest@collier.gov) confirms flood zone and base flood elevation.

Is the City of Naples part of Collier County permitting?

No. The City of Naples has its own building department. Collier GMD covers unincorporated Collier County.
