Step 1: Pre-Application and Zoning Verification

Before any plans are drawn, verify that the intended business use is allowed under the property's zoning classification. Miami-Dade municipalities (Miami, Miami Beach, Coral Gables, Doral, Aventura, and others) each have distinct zoning codes. A zoning verification letter often costs $100 to $500 and prevents months of wasted design work on an incompatible site.

Step 2: Architectural and Engineering Plan Preparation

Commercial construction in Miami-Dade requires licensed architectural plans signed and sealed by a Florida-licensed architect, plus structural, mechanical, electrical, and plumbing engineering plans. HVHZ wind-load engineering applies to any exterior modifications. Royal Custom Construction provides full design-build commercial plan packages tailored to the use category.

Step 3: Building Department Submission and Plan Review

Plans are submitted through the relevant municipality's ePlan portal (or Miami-Dade Building for unincorporated properties). Plan review typically takes 4 to 12 weeks for commercial work and runs in parallel across building, structural, mechanical, electrical, plumbing, fire department, ADA, and zoning. Each reviewer may request revisions; responding promptly to corrections is the single biggest schedule driver.

Step 4: Permit Issuance and Construction

Once all reviews approve, the building permit is issued. Construction proceeds through staged inspections — foundation, framing, rough MEP, insulation, drywall, final inspections per trade — before final approval. Inspectors must approve each stage before the next can begin.

Step 5: Certificate of Occupancy

After all final inspections pass, the building department issues a Certificate of Occupancy (CO). The CO is required before any commercial operation begins. Many businesses also need separate business tax receipts, fire department final approval, and use-specific permits (health department for restaurants, DBPR for licensed services, alcohol licensing where applicable).
