Weather exposure affects the losses a building may face and the insurance choices available to its owner. Property managers need to connect that exposure to specific coverage, maintenance and cash reserves.
Treasury’s January 2025 analysis of homeowners insurance data from 2018–2022 found higher premiums and nonrenewal rates in areas with greater expected climate-related losses. It also identifies construction costs, reinsurance, regulation and other contributing factors. Those homeowners findings provide context, not a current commercial multifamily premium forecast.
Evaluate each property’s exposure
Create a property-by-property record of likely hazards and vulnerable building systems. Review current flood information, local emergency-management guidance and site history together; a mapped zone alone does not describe every source of water damage.
- Location: elevation, drainage, nearby waterways, storm surge, wildfire exposure and access routes.
- Building: roof condition, windows and doors, below-grade spaces, electrical equipment, HVAC and exposed plumbing.
- Loss history: prior claims, repeated leaks, outage duration, repair costs and resident reports.
- Dependencies: utilities, elevators, pumps, communications and vendors needed to keep the building operating.
Rank issues by life safety, likely loss and service disruption. An active roof leak or failed drain needs a maintenance response; a structural retrofit needs a qualified design and approval.
Read the policy before comparing premiums
Ask the broker or insurer to identify covered perils, exclusions, replacement-cost assumptions, limits, coinsurance requirements and each applicable deductible. Compare those terms across renewal quotes—not just the annual price.
Flood protection
Most homeowners, renters and business insurance does not cover flood damage. Review separate flood coverage for the building and contents. NFIP coverage does not pay temporary housing/additional living expenses or business-interruption losses; those needs require a separate review.
A new NFIP policy generally has a 30-day waiting period, with exceptions such as certain mortgage transactions. Confirm the effective date with the insurer before assuming a policy bought ahead of a storm will cover that storm.
Storm deductibles
Hurricane, named-storm and wind/hail deductibles can apply under different triggers. NAIC explains that percentage deductibles commonly use insured value, not the amount of a claim. For illustration, a 2% deductible applied to a $2 million insured value is $40,000. Confirm the actual calculation and affected building in your policy.
Recovery and continuity
Ask how lost rent, utility interruption, debris removal and code-required rebuilding are treated. Check waiting periods and sublimits. A covered building repair does not establish that every related cash-flow loss is covered.
Keep a renewal calendar and begin comparison before the existing policy expires. Save signed policy documents, endorsements, invoices and the insurer’s confirmation of effective dates in an accessible location.
Prioritize resilience work
Use the exposure assessment to choose improvements rather than buying the same equipment for every property. Document the scope, installation and maintenance so the insurer can evaluate any available credit. A retrofit does not guarantee a lower premium.
- Flood: maintain drainage and pumps; evaluate moving vulnerable electrical or mechanical equipment above likely flood levels. NFIP’s mitigation guidance describes options, including flood openings, that require attention to building type and local requirements.
- Wind: inspect the roof and openings, secure loose exterior items and have qualified professionals assess connections or rated replacements.
- Heat, freeze and outages: service critical systems, monitor vulnerable spaces and evaluate backup power or pump redundancy for the loads actually needed.
- Wildfire: review site-specific vegetation and building exposure with local fire officials and qualified contractors.
Compare installed cost and ongoing upkeep with the exposure addressed, likely service interruption and any confirmed insurance benefit. Maintain reserves for deductibles and losses that remain uninsured.
Prepare residents and staff
- Share official local weather warnings and the property’s emergency contact route.
- Explain evacuation or shelter instructions and how residents will receive updates if power or internet fails.
- Keep staff and vendor contacts current; provide a way for residents to request accessible communications or assistance.
- Establish post-event check-ins, damage-reporting instructions and a clear source of updates on access and repairs.
Assign staff responsibilities for securing the site, notifying insurers and documenting damage when safe. Restrict equipment and utility shutoff tasks to trained, authorized people. Practice the communication plan before an event.
Review resident protection separately
Residents need to understand their own belongings and displacement coverage, including any flood exclusion. A resident liability waiver or benefits package does not replace the owner’s catastrophe insurance. Keep resident policy-review records separate from the building’s insurance schedule.
Your next renewal review
Bring the broker a current property schedule, loss history, replacement-cost information and documented improvements. Leave the review with confirmed coverage dates, an explanation of major gaps and deductibles, and the highest-priority building work. Revisit the plan after a loss or a significant property change.
