In an inner suburb, a cheap fitting that fails in three years is an inconvenience and a modest bill. Out here it is a wait, a drive, and a problem that sits unresolved for however long it takes somebody to get to you. That completely changes the economics of specification: buying the durable option is not an upgrade in Scarborough, it is the rational baseline.
In practice that means the most corrosion-resistant hardware available on anything exposed, mechanical arrangements in preference to ones that depend on power where there is a sensible mechanical option, and overrides that have been physically tested rather than assumed to work. A manual release nobody has ever operated is not a backup; it is a story about a backup. Where a door genuinely warrants it, that is a lock installation chosen for a twenty-year view rather than a five-year one.
The other thing worth doing properly is plant. A property running its own water storage, solar or pumping depends on that equipment in a way a suburban house simply does not, and it is frequently housed in the flimsiest structure on the plot. Bringing those enclosures up to a real standard is not about theft alone — it is about a household not losing its water or power because a door gave way.
