Postponed: Below Grade Measurement Standard Implementation


The Residential Real Estate Broker Industry Council has postponed the Below Grade Measurement Standard (BGMS) implementation, pending further review.

Originally, the implementation of the BGMS was to take effect on January 1, 2024.

The BGMS is the proposed standard by which licensees must measure below grade space should their client agree to advertise it as an additional measurement to the Residential Measurement Standard (RMS). It was not to be a mandatory measurement when advertising living space, nor part of the RMS. 

Improvement to Semi-detached and Townhouse Measurement take effect January 1

A reminder that beginning January 1, licensees will measure semi-detached and townhouse properties using the exterior wall at the foundation. If the thickness of the demising wall(s) cannot be determined, the thickness of an exterior wall should be used.

Under the current RMS, all semi-detached and attached properties are measured using interior (paint-to-paint) measurements. Attached, apartment-style properties will continue to be measured using interior measurements after January 1.

This change for semi-detached and townhouse properties will simplify the measuring process for licensees and ensure measurement standards are more accurate for consumers.
