Service life
Years in service. The band runs from the shortest to the longest life the sources state, so it shows how much they disagree, not how long 80% of units last. The line is the median of the stated lives.
Work out when yours is due for replacement
One source. This value rests on a single document (CNA e-Tool Estimated Useful Life Table, p8). Treat it as that source's figure, not a settled life, until others confirm it.

Municipal lives for exterior enclosure (B20)
23 municipalities in Ontario, British Columbia and Alberta state a life for exterior enclosure as a whole, in 18 distinct tables: 10–85 years, median 30. 33 rows come from capital asset policies (accounting lives, used for amortization) and 6 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.

Open questions
- Only one source so far: HUD planning lives for US multifamily housing. Canadian and observed sources are needed.
- Written for residential buildings in coastal areas, where the annual inspection is recommended because of salt, wind-borne debris and moisture; the interval may be conservative for inland buildings. Mirror copy hosted on maine.gov.
