The 01 E Env form must be completed by the builder or installer responsible for the building envelope work on your California construction project. Follow these steps to fill it out correctly.
Step 1: Gather Project Information
Before starting, collect these details: the project name, project address, permit number, and the name of the enforcement agency overseeing the project. The enforcement agency is typically your local building department. You will enter this information at the top of the form.
Step 2: Identify the Documentation Author
The documentation author is the person who prepared the compliance documents for the building envelope. Enter their name, company name, address, and California license number in Part 1 of the form. The author must hold a California contractor, architect, or engineer license.
Step 3: Verify Envelope Compliance
Review each item in the envelope section carefully. This section covers insulation R-values, fenestration (windows and skylights), exterior walls, roofing materials, and air sealing. Confirm that all installed materials match the specifications listed in the compliance documents filed with the building department.
Step 4: Complete the Responsible Builder Section
In Part 2, the responsible builder or installer must enter their name, company, California license number, and contact information. They certify under penalty of perjury that the installations conform to the specified requirements and all applicable California codes. If multiple contractors each have a separate scope of envelope work, they may each sign their own certificate or designate a single primary signatory for the entire project.
Step 5: Sign and Date the Form
Both the documentation author and the responsible builder must sign and date the form in the designated signature blocks. Unsigned forms are not valid for building department submission.
Step 6: Submit and Retain Copies
File the completed certificate with your local building permit office. Keep a signed copy at the construction site for all required inspections. Include a copy in the documentation package given to the building owner at occupancy. A certificate of completion for construction is often required alongside this form at project close-out.
If you have questions about which envelope sections apply to your project type, review the California Building Standards Commission guidance or contact your local enforcement agency directly.
