How to Prepare Your Commercial Building for Hurricane Season

Most commercial property managers know hurricane season is coming. Fewer have a documented plan for what to do when it arrives. Research shows 67% of commercial property management firms lack documented emergency preparedness plans and those properties experience 3.4x higher average losses per incident when something goes wrong. The cost of preparation is a fraction of the cost of an unprepared response. This checklist covers everything you need to do before June 1 to protect your building, your tenants, your insurance claim, and your business continuity.

Why Preparation Before Hurricane Season Matters More Than Response After It

• The gap between a 3-week recovery and a 3-month one is almost always decided before the storm, not during it
• Properties with pre-negotiated restoration agreements get priority crew access those without compete for capacity against every other business in the same market the moment the storm clears
• Insurance documentation established before a storm dramatically speeds up claims and reduces the risk of denial 50%+ of Helene claims and 39% of Milton claims were denied, mostly due to documentation gaps

The Commercial Hurricane Preparedness Checklist

The below steps will help you secure your building and provide peace of mind before the storm even hits.

1. Harden your building before June 1

• Roof inspection and repairs: loose flashing, aging membrane roofing, clogged drains, and weak anchor points are the most common failure points during high winds. A professional inspection in April costs a fraction of emergency tarping after a Cat 3
• Window and door protection: impact-rated glass, hurricane shutters, and reinforced door frames reduce wind and water infiltration significantly. Board-up supply lists should be confirmed before storm season — not sourced during a watch
• Seal all exterior penetrations: HVAC intake openings, pipe penetrations, and facade gaps allow wind-driven rain to enter even without direct structural damage
• Clear all drainage: clogged roof drains, gutters, and site drainage multiply flood damage fast. Clear them annually and after any significant weather event
• Elevate critical equipment: HVAC units, electrical panels, server equipment, and critical inventory in ground-level or basement areas should be elevated or relocated before June 1

2. Audit and test backup power

• A generator is only useful if it works when the power goes out. Test before June 1: load test, fuel levels, filter health, battery condition, and automatic transfer switch function
• Confirm runtime capacity: know how many hours your generator can run critical systems and what fuel resupply looks like if the storm disrupts local supply chains
• Critical systems to keep online: fire suppression, security, communications, refrigeration if applicable, and elevator systems in multi-story buildings
• Have a manual override plan for every system that relies on power — elevators, access control, HVAC — in case the generator itself fails
• 360 TEMP POWER SERVICE: If your building loses power and your generator fails, 360 Fire & Flood can set up temporary power on-site during CAT events upon request available on a first-come-first-served basis. Having an emergency response agreement in place before storm season is the best way to secure your spot.

3. Document your building before the season starts

• Pre-storm documentation is what protects your insurance claim. Walk every floor, room, and exterior surface and document current conditions with photos and video before June 1
• Record serial numbers and current values of major equipment, HVAC systems, and high-value contents
• Back up all records digitally in a location accessible from your phone — not just a computer that may lose power or be physically damaged
• Store insurance policy numbers, adjuster contacts, vendor contacts, and 360s emergency line in a single accessible document your facilities team can reach from anywhere

4. Review your insurance coverage

• Wind and structural damage: typically covered under standard commercial property policies
• Flood and storm surge: almost always requires a separate flood insurance policy or NFIP coverage this is the gap that devastated commercial operators after Helene

5. Build your emergency communications plan

• Assign clear roles before any storm: who monitors weather updates, who authorizes evacuation, who contacts the restoration partner, who communicates with tenants and employees
• Create a communications tree: tenant notification templates, employee check-in protocols, and contact lists that work without email if power goes out
• Know your local evacuation zones and routes: confirm which zones your properties fall in and what local authority trigger points are for mandatory evacuation orders
• Post emergency contacts visibly on-site: utility shut-off locations, emergency contacts, and building manager information should be physically posted in every building – not just stored digitally

The Step That Changes Your Recovery Timeline: A Pre-Loss Assessment

Generic checklists treat every building the same, a Pre-Loss Assessment identifies your specific vulnerabilities before they become losses.

• 360s Pre-Loss Assessment documents weak points in your building envelope, drainage, electrical, and mechanical systems
• Creates a custom emergency response plan and establishes 360 as your contracted partner
• Documentation created during the assessment supports insurance negotiations and speeds up claims when a loss does occur
