Which of the following is included in square footage according to CREA recommendations?

The Canadian Real Estate Association (CREA) guidelines stipulate that square footage measurements should encompass specific areas of a property to provide an accurate assessment of usable space. Cantilevers, which are portions of a structure that extend beyond the foundation or support and are not supported on the ground, are included in square footage calculations as they contribute to the overall footprint and functional living space of a property. Including cantilevers helps agents and potential buyers understand the total usable area available, which can be a significant factor in a property's value and livability.

In contrast, the other options typically have different criteria for measurement. For instance, finished area below grade is generally not included in above-grade square footage calculations because it refers to spaces that are below the main foundation level, which can vary in usability compared to full above-grade living areas. Porches and garages may also be excluded from square footage assessments depending on local practices and the specifics of the sale; porches might be considered as outdoor or semi-outdoor spaces and garages often serve non-living purposes. Thus, the inclusion of cantilevers is aligned with CREA's recommendations for a comprehensive representation of the livable square footage of a property.
