Communities, ICC 700)
Raze and Site Work Permit
Building Inspections



Green and Energy Inspections integrated into the
inspection process, will occur simultaneously with other
required inspections
All projects required to use third party to complete
performance testing:
 Commissioning, Air Leakage Tests, Duct Leakage
Tests
No Green Third Party Inspections
Certificate of Occupancy


Green Code requires a number verifications prior to
issuance of a certificate of occupancy
 First CofO for a floor above grade plane in projects
where there are multiple certificates of occupancy
If project must meet post-occupancy requirements, a
CofO will not be granted unless the code official
determines that the project is on track to be verified in
accordance with the path selected
Certificate of Occupancy

GBA: Financial Security prior to issuance of a certificate
of occupancy by one of four methods:
 Cash
 Irrevocable letter of Credit
 Bond
 Binding Pledge
Post Occupancy


Green Building Act and Green Construction Code allow
for verification after a building is occupied for some of
the green building requirements
Due dates vary :
 Pay close attention to when your documentation is
due to avoid any issues and/or fines
 If using a third party verification system be sure to
familiarize yourself with the deadlines for those
programs to ensure your project remains eligible
Sectional Reference Guide
 Section Summary
A detailed summary of each code section that gives additional guidance,
considerations, design details, and other resources that will help building
professionals develop a deeper understanding of the code section, connect
the dots to larger green building topics, and “read between the lines” of the
specific code section.
 Rationale, Benefits and Intention
A summary that states the importance of the section and why it is included in
the green or energy code
Sectional Reference Guide
 Best Practices
A list and description of industry best practices that are used to implement
and meet the requirements of each code section, specific to the District’s
climate zone
 Innovations
A list of innovative techniques, products, and/or methods that are being used
to successfully implement each code section
 Timeline
Guidance on when in the construction timeline the section should ideally be
considered and addressed by the project team
Sectional Reference Guide
 Resources
A list and description of critical journals, supplementary codes, web
resources, books, and other resources that can be used for additional
guidance when applying the green and energy codes
 Related Codes and Referenced Standards
A list of references to related ICC codes, other codes, and/or other referenced
standards in each section.
Additionally, lists of all pre-approved agencies, processes, sources, standards
and other references throughout the Green Construction and Energy
Conservation Codes that site an “approved” alternative to the stated code
language.
