InterNACHI's Estimated Life Expectancy Chart for Florida Homes

The following chart details the predicted life expectancy of appliances, products, materials, systems and components for homes in the state of Florida.  (It may also be applicable to states in the nearby coastal region with similar climate and weather conditions on a typical basis.)  
While many components and systems in homes located in Florida and the surrounding area have service life expectancies that are comparable to those anywhere else in the U.S., those items that are regularly exposed to saltwater, wind, sun and heat are particularly vulnerable to premature failure compared to items installed in homes located elsewhere.  These guidelines attempt to address those differences. 
Furthermore, Florida inspectors are subject to state requirements for reporting deficiencies based on expected service life:
468.8323 Home inspection report.  Upon completion of each home inspection for compensation, the home inspector shall provide a written report prepared for the client.

(1) The home inspector shall report:
(a) on those systems and components inspected that, in the
     professional opinion of the inspector, are significantly deficient or
     are near the end of their service life;
(b) if not self-evident, a reason why the system or component reported
     under paragraph (a) is significantly deficient or near the end of its
      service life.
(For a comparison of service life expectancies in other areas of the U.S., see InterNACHI's Estimated Life Expectancy Chart for Homes.)
Consumers, inspectors, and professionals advising their clients should note that these life expectancies have been determined through research and testing based on regular recommended maintenance and conditions of normal wear and tear, and not extreme weather (or other) conditions, neglect, over-use or abuse.  Therefore, they should be used as guidelines only, and not relied upon as guarantees or warranties.  


Surface preparation and paint quality are the most important determinants of a paint's life expectancy. Ultraviolet (UV) rays can shorten life expectancy, especially in coastal regions that experience a lot of sunshine and heat, as well as wind-driven rain.  Additionally, conditions of high humidity indoors or outdoors can affect the lifespan of these components, which is why they should be maintained seasonally.

Appliance life expectancy depends to a great extent on the use it receives. Furthermore, consumers often replace appliances long before they become worn out due to changes in styling, technology and consumer preferences.
