When a permit is required
Permit triggers and exempt work for Anderson
Building work requiring plan review is handled through the Building Division permit process. Existing accessory dwelling units built without permits may still require permit application to legalize the work. ADUs and junior ADUs are stated as requiring permits when constructing or adding residential units.
Note: The city publishes a Project Exempt from Permits handout in its permit-forms section, but the linked source could not be opened in this research environment and no explicit exempt-work list was visible in the accessible text reviewed. Confirm exemptions directly with the Building Division before starting work.
- Complete permit application with property, applicant, and permit-holder information
- Plans drawn to scale and complete for the scope of work, including soil, drainage, structural, and MEP sets where applicable
- Signed and sealed design professional plans where required
- Contractor declaration where applicable
- Owner-builder forms where applicable
- Building code
- City pages link to the California state code family through DGS, and the ADU guide states review for California code health, life-safety, and energy requirements. Current adopted local amendment package or exact code edition should be confirmed directly with the Building Division.
- Permit validity
- Plan review becomes null and void after six months if no permit is issued. Unaccepted plan data may be returned or destroyed.
- Owner-builder
- Owner-builder permit requires the property owner acknowledgment and personal sign-off, plus verification requirements for owner signatures. Owner-builders can remain the legal and financial party of record.
- Contractor requirements
- Contractor declaration requires a California license in force. Owner-builder materials say owners must verify that hired contractors are properly licensed and workers' compensation compliant.
