Jacksonville Site Plan

Jacksonville operates a consolidated city-county government through Duval County. That means one permit office — the Building Inspection Division — reviews plans for the entire county. Before BID even touches your application, it routes through the Development Services Division (Zoning, Drainage, DMG), the Fire Marshal if triggered, and potentially FEMA/Flood and Historic review agencies.

Each of those reviewers can independently place your file in Return for Corrections status. BID doesn’t start its review until every upstream agency clears the application. One missing note in the zoning section adds weeks before the structural review begins.

The most common reasons Jacksonville residential permits return for corrections:

1. Finished floor elevation not shown relative to BFE Jacksonville sits in one of Florida’s most flood-active counties. AE zones cover large portions of the city — along the St. Johns River, Ortega River, Ribault River, and their tributaries. The Florida Building Code requires new construction to be elevated at least 1 foot above Base Flood Elevation. If your plan doesn’t show the flood zone designation, the FEMA panel number, the BFE, and the proposed finished floor elevation — it comes back before BID opens the file.

2. Grand tree not located, no tree protection plan Jacksonville’s tree ordinance (Ordinance Code Chapter 656, Part 12) creates three tiers of protection. Grand trees — any species at 24 inches DBH or more — require a Planning Commission variance for removal and must be shown on the site plan with drip-line protection barriers. Specimen trees at 12″+ DBH require 1:1 caliper-inch mitigation. Heritage species like live oak and magnolia trigger additional review at 18″+ DBH. A plan that doesn’t show these trees doesn’t pass the Zoning section of DSD review.

3. Impervious surface calculation absent or wrong Jacksonville’s stormwater regulations tie to the SJRWMD (St. Johns River Water Management District). Projects that create more than 4,000 square feet of impervious surface or disturb more than an acre may trigger an Environmental Resource Permit. Even below that threshold, your site plan needs to show the impervious surface tally — house footprint, driveway, walkways, patio — and demonstrate it doesn’t exceed the zoning district’s lot coverage limits.

4. Setbacks measured to foundation rather than to the furthest projection Florida Building Code measures setbacks to the most-projected building element — eave, overhang, gutter, or cantilevered floor. Plans that measure to the foundation edge get redlined at BID. In RLD-60 zoning (the most common Jacksonville residential district), front setbacks are 25 feet, rear 20 feet, sides 7.5 feet — all measured correctly.

5. Wetland boundary absent or undifferentiated from uplands Jacksonville has extensive wetland coverage across its 875 square miles. If your parcel borders a jurisdictional wetland, the site plan must show the delineated wetland boundary and the proposed buffer. Without it, the application triggers SJRWMD and Army Corps review flags that can add months.

6. ADU exceeds 25% of primary structure or 750 square feet Jacksonville caps detached ADUs at the lesser of 750 square feet or 25% of the primary structure’s square footage. ADUs also cannot exceed the height of the primary residence. Plans submitted without these calculations verified get returned before the first structural review.
