Site Plan Approval Process for Commercial and Residential Development in South Florida 2026

Before building permits can be issued for new construction, additions, or changes of use on most commercial, institutional, and multifamily residential properties in South Florida, site plan approval must be obtained from the applicable planning and zoning authority. Site plan review is a separate regulatory process from building permit plan review — it focuses on land use compatibility, traffic impact, parking, landscaping, stormwater management, and design quality rather than building code compliance. Understanding the site plan approval process — including which projects trigger it, what documentation is required, and how long it takes — is essential for any South Florida development project timeline.

What Projects Require Site Plan Approval?

Site plan approval requirements vary by municipality, but most South Florida jurisdictions require site plan review for: new commercial, industrial, or multifamily residential buildings above a certain size threshold; changes of use that increase traffic generation or parking demand; site alterations affecting more than a specified percentage of the lot; additions exceeding a defined size threshold; and projects in special overlay zones or districts where enhanced design review is required.

In the City of Miami, site plan review is required for all development above specified size thresholds under Miami 21 — including projects that require Urban Development Review Board (UDRB) approval. In Miami-Dade County's unincorporated areas, site plan review is required for many commercial and multifamily developments. In Broward County municipalities and Palm Beach County municipalities, site plan requirements vary by city code.

Site Plan Application Documentation

A typical site plan application package includes: a completed application form; a current boundary survey of the property; a site plan drawing at an appropriate scale showing the property boundaries, existing and proposed structures, setbacks, building footprint, parking spaces and circulation, landscaping areas, vehicular and pedestrian access points, stormwater management features, dumpster enclosure location, utility easements, and signage locations; architectural elevations showing the proposed building exterior design; a civil engineering stormwater plan; a traffic study (required for projects above specified trip generation thresholds); a landscape plan prepared by a licensed landscape architect; and payment of USD application fees.

USD site plan application fees in South Florida municipalities range from $500 USD for minor residential site plan reviews to $25,000 USD or more for large commercial or mixed-use development site plan applications. Application fees are typically non-refundable even if the application is denied or withdrawn.

Site Plan Review Staff Review vs. Public Hearing

Most South Florida municipalities have a two-tier site plan review process. Administrative review (staff review) handles straightforward projects that comply with all code requirements — staff reviews the application against applicable standards and approves, approves with conditions, or denies the application without a public hearing. Administrative review in most South Florida cities takes 30 to 60 business days from a complete application submission.

Development review board or planning board public hearings are required for projects that require variances, special exceptions, or waivers from standard code requirements; for projects above certain size thresholds; for projects with significant traffic or environmental impacts; and for projects in special overlay districts. Board hearings are quasi-judicial proceedings subject to procedural due process requirements. Neighbors receive notice by mail and may appear to support or oppose the application.

DRC — Development Review Committee Process

Many South Florida municipalities use a Development Review Committee (DRC) process for site plan review — a multi-disciplinary technical review where representatives from the building department, planning department, engineering department, fire department, utilities, and other agencies review the site plan application simultaneously and provide coordinated comments.

The DRC process is more efficient than sequential review (where each department reviews after the prior department completes) because all departments see and respond to the application at the same time, reducing total review time. DRC meetings are typically scheduled 2 to 4 weeks after application submission, with written comments provided to the applicant following the meeting. The applicant revises the application in response to DRC comments and resubmits. The number of revision cycles required depends on the quality of the initial application and the complexity of the project.

Traffic Impact Analysis Requirements

Commercial, industrial, and multifamily developments above specified trip generation thresholds must submit traffic impact analyses (TIAs) with their site plan applications. A TIA is prepared by a licensed traffic engineer and analyzes the project's projected peak hour traffic generation, the distribution of that traffic on the surrounding road network, the level of service impact at key intersections, and any required traffic mitigation measures (turn lanes, signal timing modifications, roadway improvements).

Traffic impact fee payments — USD assessments based on the project's trip generation — are required as a condition of development approval in most South Florida jurisdictions. Traffic impact fees for commercial developments can reach $100,000 USD to $500,000 USD for large projects with high trip generation. These fees must be paid before building permits are issued.

Concurrency Management and Adequate Public Facilities

Florida's Growth Management Act requires that development approvals demonstrate concurrency — that public infrastructure (roads, parks, schools, utilities) has adequate capacity to serve the proposed development before development is approved. South Florida municipalities and counties maintain concurrency management systems that track available capacity and allocate it to approved developments.

Properties with approved site plans and development orders receive concurrency reservations that protect their allocated capacity for the duration of the development order. If a development order expires before construction is completed, the concurrency reservation may be lost and a new concurrency determination may be required. USD concurrency application fees are separate from site plan application fees.

Site Plan Expiration and Extension

Approved site plans have defined validity periods — typically 12 to 24 months from the approval date for administrative approvals, and sometimes longer for development order approvals from development review boards. If a building permit application is not filed before the site plan approval expires, the site plan must be resubmitted and reapproved before building permits can be issued. In rapidly changing code environments, a resubmitted site plan may face different requirements than the original approval.

USD fees for site plan extension requests are typically a fraction of the original application fee — from $100 USD to $1,000 USD for most South Florida jurisdictions. Extensions are usually available for one or two additional terms before full reapplication is required. Property developers should monitor their development approval expiration dates carefully and file extension requests before expiration — retroactive extensions are not always possible.
