Application Process

1. Confirm the project is inside Willits city limits and gather all supporting documents before starting the application.
2. Complete the building permit application online through the iWorQ portal or obtain/download the application from the Building Department.

Permit validity

The city application says an application is deemed abandoned 1 year after filing if no permit has been issued. The city also provides a permit extension form. The city page reviewed does not publish issued-permit expiration rules. Because Willits applies the 2022 California Building Code, permit expiration generally follows the current California rule that a permit remains valid if work starts within 12 months and is not abandoned; confirm this with the Building Department before relying on it.

Building code

The city states it uses the 2022 California Building Code. Project documents and city materials also reference the 2022 California Residential, Electrical, Plumbing, Mechanical, Fire, and CALGreen codes as applicable.

Owner-builder

The application allows the applicant to proceed as a California licensed contractor, the property owner, or an authorized agent. Separate owner verification and separate owner-agent authorization are required where applicable.

Contractor requirements

The application requires the signer to affirm they are licensed under Chapter 9 of Division 3 of the California Business and Professions Code unless applying as owner-builder or authorized agent. The online portal also says a City of Willits business license application packet is required when doing business within city limits.
