What are the typical life expectancy ranges for materials and components?

Note: Life expectancy varies with usage, weather, installation, maintenance, and quality of materials. Items listed as lasting 25+ years, especially those that open and close, often fail prematurely due to misuse or overuse. Use this list only as a general guideline, not as a guarantee or warranty regarding the performance or life expectancy of any product. Final determinations of life expectancy are dependent upon each individual situation.

When calculating Tenant Charges for Security Deposit Accounting, the Tenant's financial liability must be based upon the life-expectancy and age of the item. When a household fixture or appliance needs replacing due to tenant abuse or neglect, the remaining "useful life" of the item must be determined before a Landlord can assess a portion of the replacement cost against the tenant's security deposit. See below life expectancy guides and see additional examples on the Appendix 5D Life Expectancy Chart in the HUD Claims Guide.
