Motivation • Why do we need a measuring standard?

Motivation • What is it? – Voluntary Guidelines for describing, calculating, measuring, and reporting of area for Single Family Residential (SFR) attached, detached & semi-detached (Duplex) homes.

Motivation • In the beginning…

Motivation • There was…, Gross Living Area (GLA) • “Total area of finished, above-grade residential space; calculated by measuring the outside perimeter of the structure and includes only finished, habitable, above-grade living space. (Finished basements and attic areas are not generally included in total gross living area. Local practices, however, may differ). ” • The Dictionary of Real Estate Appraisal, 5 th ed.

Motivation • Why do we need it? Ø Inconsistent Measuring Methods • Exterior area Measuring • Interior area Measuring • Mixture of both

Motivation • Why do we need it? Ø Different Measurers & Uses • Appraiser • Assessor • Realtor

Motivation • Appraiser

Motivation • Assessor

Motivation • Realtor

Motivation • Why do we need it? Ø Differing SF Measuring Methods Cause • Confusion • Inconsistent Results • Conflict

Motivation One of the most common reasons appraisers & realtors get sued is over measuring disagreements

Motivation Consistent measuring methods reduces liability

Motivation • History Behind Z 765 Standard Ø Building Owners & Managers Association (BOMA) • 1915 develop commercial building measurement standard • Current Version: Z 65. 1 -2010 (Commercial buildings) Ø NAHB • • 1994 NAHB research begins work on residential standard First Version: Z 765 -1996 Previous Version: Z 765 -2003 New Version: Z 765 -2013 – Summer 2013

Z 765 -2013 Components • Components of the ANSI Z 765 Standard Ø Gross Living Area (GLA) § For units in condominium or cooperative projects, use interior perimeter unit dimensions to calculate the gross living area. In all other instances, use the exterior building dimensions per floor to calculate the above-grade gross living area of a property. Only finished abovegrade areas should be used— garages and basements (including those that are partially above-grade) should not be included. FNMA Guidelines: XI, 405. 06 (11/01/2005)
