DIVISION 5.7 ADDITIONS AND ALTERATIONS TO EXISTING NONRESIDENTIAL BUILDINGS
This is a new division proposed to include standards for additions and alterations to existing nonresidential buildings. The reason for this proposal is to extend the benefits of reduction in greenhouse gas emissions, water use, and polluting finish products to a larger class of buildings than newly constructed buildings. It is modeled after similar provisions recently adopted locally by the City of Los Angeles for its considerable body of construction projects. It proposes and scopes some of the provisions from Divisions 5.3 through 5.5 for which cost benefit analysis was prepared last cycle for the mandatory code. The provisions are those readily applicable to additions and renovations.
SECTION 5.701 – ADMINISTRATION
CALGreen Section: 5.701.1 Scope. For those occupancies subject to section 103 of this code, the provisions of this division shall apply to the planning, design, operation, construction, use and occupancy of additions to buildings or structures unless otherwise indicated in this code. The provisions of this Division shall only apply to the portions of the building being added or altered within the scope of the permitted work. Compliance for additions and alterations is required on or after the dates shown in Table 5.701
TABLE 5.701
| Effective date of compliance | Square footage of addition |
Permit valuation or estimated construction cost of alteration |
| July 1, 2012 | 2000 | $500,000 |
| Effective date of the 2013CaliforniaBuildingStandards Code | 1000 | $200,000 |
Notes:
1) The effective date of the 2013 California Building Standards Code is currently projected to be January 1, 2014.
2) This division does not apply to additions and alterations of qualified historical buildings.
Intent: Scope for additions and alterations to existing nonresidential buildings is limited to 2000 s.f. for additions and $500,000 for alterations, with that limit to drop in the next edition of the code. At the request of the Division of the State Architect, this section also includes an exception for qualified historic buildings regulated by that agency.
Existing Law or Regulation:
Building standards generally apply to additions and alterations for which a permit is applied. CALGreen has an exception, applying only to newly constructed buildings, so this division aligns CALGreen with other Parts of Title 24. There may be a more stringent local ordinance in place.
Compliance Method:
Determine if the addition or alteration triggers compliance (see Section 5.701 above and Section 7.502 Definitions) then comply with the specific provisions applicable.
Enforcement:
Plan Intake: The reviewer and/or plan checker should review the plans, specifications for the areas of additions and construction cost estimates for alterations for to confirm the need for compliance.
On-Site Enforcement: The inspector should review the permit set of plans and product data sheets for compliance with specific provisions, following.
