Key Takeaways
- Review the Landlord Work Letter and Lease Exhibit B with a licensed commercial GC before executing your lease.
- Understand the delivery condition: "Cold Dark Shell" vs. "Warm Vanilla Shell" can shift build-out costs by $40 to $90+ per square foot.
- Mechanical, Electrical, and Plumbing (MEP) lead times and county plan reviews typically drive your critical path schedule.
- Always establish a 10% to 15% pre-construction contingency for existing hidden code compliance issues (electrical panels, ADA path of travel).
Signing a commercial lease on an office, medical suite, restaurant, or retail storefront in Florida is a massive milestone. But the period between lease signing and your grand opening is where profits are won or lost. Every week of construction delay can mean paying rent on an unopened space while your operations remain halted.
1. Understanding Shell Conditions: The Starting Point
Before negotiating your Tenant Improvement (TI) allowance, you must understand exactly how the landlord will deliver the premises:
- Cold Dark Shell: Bare concrete slab (often untrenched for plumbing), exposed exterior block walls, no drywall, no HVAC distribution, and raw electrical service brought only to the main service panel. Build-out costs typically range from $85 to $160+ per square foot depending on medical/food/office specs.
- Warm Vanilla Shell: Finished drywall on perimeter walls, acoustical drop ceiling installed, basic lighting grid, concrete slab poured, and working HVAC unit with basic ducting. Build-out costs typically range from $45 to $85 per square foot.
- Second-Generation Space: A previously occupied suite. While some walls and MEP feeds may be reusable, retrofitting outdated electrical circuits or moving commercial plumbing can sometimes cost as much as building new.
2. Negotiating the Landlord Work Letter & TI Allowance
The Tenant Improvement Allowance is money the landlord credits toward your build-out. To maximize its value:
- Define Disbursal Terms: Will the landlord pay your general contractor directly via progress billing and lien releases, or reimburse you post-Certificate of Occupancy? Direct progress billing protects tenant cash flow.
- Include HVAC Replacement Clauses: If the rooftop HVAC unit is over 10–12 years old, negotiate for the landlord to replace or warrant it. In Florida's summer climate, a failed commercial RTU can cost $12,000–$25,000 unexpectedly.
- Secure Adequate Free-Rent Period: Ensure your rent-commencement date allows a realistic construction and permitting window (typically 90 to 150 days in Florida municipalities).
3. Florida ADA & Life-Safety Code Compliance
Commercial build-outs must comply with the Florida Americans with Disabilities Act (FBC Chapter 11) and NFPA Life Safety Code:
- Restroom Ratios & Turning Radii: Single-occupancy and multi-stall ADA restrooms require precise 60-inch turning clearances, grab bar backing, and grab-bar height dimensions.
- Path of Travel: County inspectors will verify accessible door clearances (minimum 32-inch clear opening), panic exit hardware, and accessible routes from the parking lot to your reception area.
- Fire Suppression & Egress: Modifying partition walls often requires relocating sprinkler heads, exit signs, and emergency strobe strobes to maintain required coverage.
Pro Tip
Involve your General Contractor in the pre-lease site walkthrough. A 45-minute inspection can reveal if the electrical panel has available breaker space, if the sanitary sewer line is deep enough for grease trap slopes, or if unpermitted prior work requires remediation.
4. The Phased Construction Timeline
- Weeks 1–3: Architectural space planning, MEP engineering drawings, and landlord architectural review.
- Weeks 4–7: City/County building department submission, plan review, and permit issuance.
- Weeks 8–10: Demolition, metal stud framing, in-slab rough plumbing, and electrical conduits.
- Weeks 11–13: Rough mechanical/electrical/plumbing inspections, insulation, and drywall hanging/finishing.
- Weeks 14–16: Millwork, flooring, ceiling tiles, paint, fixture installation, and final inspections for the Certificate of Occupancy.
