Residential Measurement Standard

The Real Estate Council of Alberta (RECA) adopted a new Residential Measurement Standard (RMS) at its April 2016 meeting, and issued a revised Guide to the Residential Measurement Standards in Alberta in May 2016.

Residential Measurement Standard - Frequently Asked Questions

Principles of the Residential Measurement Standard:

1. Real estate professionals must use the RMS.

2. Identify if the measurement system is metric or imperial, and apply it consistently. Measurements must be calculated to within 2% of the RMS size.

3. For detached properties, measure the property using the exterior wall at the foundation.

4. For properties with common walls, such as half-duplexes, townhouses, and apartments, measure the interior perimeter walls (paint-to-paint) at floor level. An additional area representation may be made assuming exterior measurements.

5. Include floor levels that are entirely above grade and exclude floor levels if any portion is below grade. Below grade levels may be measured, but the area must not be included in the RMS area.

6. Include all additions to the main structure and conversions of above grade areas within the structure if they are weatherproof and suitable for year-round use.

7. The property must have a minimum floor-to-ceiling height of 2.13 metres (7 feet). If the ceiling is sloped, the area with a floor-to-ceiling height of at least 1.52 metres (5 feet) is included in the RMS area, provided there is a ceiling height of 2.13 metres (7 feet) somewhere in the room.

8. Include extensions from the main structure that have a minimum floor-to-ceiling height of 1.5 metres (5 feet), such as cantilevers, bay and bow windows, and dormers.

9. Exclude open areas that have no floor, such as vaulted areas.
