Course Descrip/on This session will focus on the “Check Height and Area” software that reviews and analyzes building height and area compliance with the 2013 California Building Code (CBC), including the July 2015 supplement, for buildings up to six stories, with up to four occupancy groups at each level. This user-friendly application is created for design professionals and building officials to ease building code analysis. Step-by-step instructions will be provided and common issues related to height and area limitations will be illustrated with examples of actual mixed occupancy group, multi-story buildings.

Learning Objec/ves

•  Explore how to save time by using software to calculate grade plane for a variety of topography situations.

•  Discuss how to optimize building height and area values for all occupancy groups and types of construction using software as an aid.

•  Evaluate methods of calculating frontage increases to aid in building design and plan review.

•  Review calculation procedures for allowable height, area, and number of stories for a mid-rise structure

•  Defini<ons (502) •  General Height and Area Limita<ons (Table 503) •  Building Height (504) •  Mezzanines and Equipment Pla\orms (505) •  Building Area Modifica<ons (506) •  Unlimited Area Buildings (507) •  Mixed Use and Occupancy (508) •  Incidental Uses (509) •  Special Provisions (510)

Download Heights and Area Calculator. More Online Calculators

What does Cha-‐Cha do? •  Checks and analyses Building Height and Area in compliance with the 2007, 2010 & 2013 CBC for buildings up to 6 stories, with up to 4 occupancy groups at each level. •  Op<mizes design values for all occupancy groups and types of construc<on using single applica<on •  Calculates Frontage increase (I f) •  Calculates Grade plane eleva<on for any topography

How to use Cha-‐Cha? •  Select proposed Type of construc<on

–  Cha-‐Cha will show max. permiDed height for the building without sprinklers per Table 503

•  Input proposed Building Height (f) •  Input proposed number of stories (6 max) •  If applicable, check the box for sprinklers throughout per 903.3.1.1 or 903.3.1.2

–  No subs1tu1on for 1-‐hr construc1on •  If applicable, input (I f) value •  Select Occupancy Groups (4 per level) •  Input corresponding areas (sq. f.)

Cha-‐Cha will check:

Allowable height, number of stories and the area for: •  Each Occupancy group at each floor •  Each floor •  Each Occupancy group throughout En1re building •  Overall building

Abbrevia/ons used in Cha-‐Cha

•  CHA -‐Check Height and Area •  NP -‐Not PermiDed •  OL -‐Over PermiDed Limit •  SPA -‐Sprinklers used for Area increase •  SPH -‐Sprinklers used for Height increase •  SPS -‐Sprinklers used for Story increase •  UL -‐Unlimited

Code Sec/ons not covered by Cha-‐Cha

•  503.1.1 (Special industrial occupancies) •  Footnote b of Table 503 •  504.3 (Roof structures) •  505 (Mezzanines) •  507 (Unlimited Area Buildings)

–  for Frontage increase (If), Cha-‐Cha considers the Excep1on under Sec. 506.2.1)

•  510 (Special provisions)
