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.

What this entry needs
- Service life sources: municipal asset management plans and capital asset policies that state a life for it, manufacturer literature, or open research.
- Maintenance tasks: manufacturer manual requirements, and standards referenced by clause number.
- Replacement records: install and removal dates from real buildings. These are what eventually earn an entry grade A.

For agents
map_classification on the MCP server already matches asset register names like “HM door” to door-exterior-hollow-metal, and returns entry_published: false until an entry exists.
