Building Design - 2016 Code Criteria

Applicable Codes and Standards

2016 California Building Code (based on the 2015 International Building Code)
2016 California Residential Code (based on the 2015 International Residential Code)
2016 California Electrical Code (based on the 2014 National Electrical Code)
2016 California Plumbing Code (based on the 2015 Uniform Plumbing Code)
2016 California Mechanical Code (based on the 2015 Uniform Mechanical Code)
2016 California Fire Code (based on the 2015 International Fire Code)
2016 California Green Building Standards
2016 California Energy Efficiency Standards

Seismic

Seismic Design Categories, SDC, are based on specific site locations. Values for spectral response accelerations, S1 and SS, and damped spectral response accelerations, SD1 and SDS, may be determined by entering longitude and latitude at the USGS seismic design maps application . These values, along with the risk category (most buildings in Santa Cruz County will be risk category I, II or III, with residences as Occupancy Category II), will determine the SDC. Most of Santa Cruz County will be SDC D or E. Use site soil Class D, unless a geotechnical report determines otherwise. For structures required to have a structural analysis (non-conventional), See ASCE Standard 7-10, Chapter 11, for complete Seismic Design Criteria.

Wind

  Vult is 110 mph for Risk Category II buildings (most buildings). Exposure categories B (urban and suburban areas), C (open terrain with scattered obstructions or areas that are not Exposure B or D) or D (unobstructed areas and ocean front areas). For structures required to have a structural analysis (non-conventional), See ASCE Standard 7-10, Chapter 26, for complete Wind Design Criteria

Wildland-Urban Interface

Those areas mapped in a State Responsibility Area, SRA, shall comply with the Materials and Construction Methods for Exterior Wildfire Exposure in 2013 CBC, Chapter 7A for non-residential and 2013 CRC R327 for one and two family dwellings and townhomes. The county's GIS will determine if a project is in a State Responsibility Area, SRA. See WUI Codes for CBC 7A requirements, which generally mirror CRC R327 requirements.

Climate Zone

For energy compliance, use Climate Zone 3. See the California Energy Commission's website.
