How long does a garbage disposal last?

For dwelling units, the U.S. Department of Housing and Urban Development (HUD) lists Disposal (food waste) at 7 years in Family and 10 in Elderly (Numbering by ASTM 2018-08 Outline, no issue date, read 2026-10-24, national, multifamily, n not published by the source). Both are multifamily capital-planning lives, not a measured life.

For property managers, landlords and HOA boards

Fannie Mae's disposal figure is for a common area. In “INTERIOR / COMMON AREA FINISHES”, “Common area disposal” receives 5 years in the “Multifamily / Coop” column (table version 10/14, read 2026-10-24, national, multifamily, n not published by the source). The document is a multifamily property-condition-assessment table; this is a planning entry, not a measured life of a disposal inside a dwelling unit. Its “DWELLING UNIT FIXTURES” kitchen list names “Kitchen: Cabinets (wood construction)”, “Kitchen: Cabinets (particle board)”, “Kitchen: Dishwasher”, “Kitchen: Microwave”, “Kitchen: Range”, “Kitchen: Range-hood” and “Kitchen: Refrigerator”. No disposal appears in that kitchen sequence. The Fannie Mae introduction includes this description: “the EUL tables may include items that are typically considered general maintenance and repair items to be handled by in-house maintenance staff.”

HUD lists “Disposal (food waste)” in “Interiors-Dwelling Units” and “Disposal (food waste) - Common” in “Interiors-Common Areas”. Both sit under “Appliances” and carry the same entries: 7 years in the Family column and 10 years in the Elderly column (Numbering by ASTM 2018-08 Outline, no issue date, read 2026-10-24, national, multifamily, n not published by the source). These are multifamily capital-planning lives, not a measured life of the appliance at a particular sink. The excerpt prints Family and Elderly as column headings without defining them.

To have a garbage disposal put in under your sink, you can post the job on InstaBids and compare written bids from contractors.

Installation prices have their own sources on the national cost page: How much is garbage disposal installation?

Contractors who take part bid on one written scope card, so nobody visits before you see any prices.
