When terms are not defined, the best approach is to look at common-law decisions that help define these terms.
1) In McLaren v. Castlegar (City), 2010 BCSC, three standards of “dilapidated” are introduced:
a) that the renovation/repair of a building would exceed one half of its assessed value, and/or
b) that the cost of remediation exceeds the reasonable estimated cost of demolition and rebuilding of a similar structure.
c) that the structure is uninhabitable in its present condition
The report for the Castlegar officials reads, in part:
“... the building is now at the point that more than fifty per cent (50%) of its assessed value has been affected. Due to the aforementioned conditions, in my opinion the buildings are uninhabitable in their current condition and pose a risk to any person entering into these buildings and should be demolished or repaired immediately. In my opinion, based on the current condition of the buildings the cost to repair the buildings to the standards in the B.C. Building Code 2006 and all other applicable enactments has the potential to exceed the costs of demolishing the buildings and rebuilding.”
2) Watters and Town of Glace Bay, 1987 NSSC repeats the general principle of considering a building dilapidated if the cost of repair exceeds the value of the building.
3) White v Amherst (Town), 2019 NSSC also relied on the test of occupancy or habitability. The building in question was not deemed structurally unsound, but was of such a state if disrepair that it was deemed unfit for occupancy.. An order to demolish was ultimately issued, and deemed reasonable by the Court.
4) In Kamsack (Town) v Kaushik, 2014 SKCA, officials with the Town of Kamsack used the test that demolition was appropriate where the cost of required work exceeded the value of the property. Language used by engineers speaks to this approach:
“Due to the extensive upgrades required to the unit to meet acceptable Engineering Standards for residential housing, it is considered uneconomical to do so. We therefore recommend the unit be demolished and the site property be levelled.”
These four cases (among others) introduce an objective framework for what some may consider a subjective approach.
