What is the strata obligation to replace or repair the common property's windows?

18. The strata’s obligation to repair and maintain is measured by the test of what is reasonable in all circumstances and can include replacement when necessary (see The Owners of Strata Plan NWS 254 v. Hall, 2016 BCSC 2363). The standard is not one of perfection. When deciding whether to fix or replace common property or parts of a strata lot the strata must repair, the strata has discretion to approve “good, better or best” solutions to any given problem. The court, and by extension the CRT, will not interfere with a strata’s decision to choose a “good,” less expensive, and less permanent solution, although “better” and “best” solutions may have been available (see Weir v. Owners, Strata Plan NW 17, 2010 BCSC 784 at paragraphs 28 and 29). In other words, the strata is not required to replace the applicants’ windows if there are other reasonable repair options open to it.
