General Requirements

State and city law requires design approval and plan check before a building permit issues. Most construction work requires permits; exemptions are listed in municipal code rather than in a single short list.

Required Documents

• Residential Permit Application (B-1) with signatures and ownership/applicant details. Construction plans (minimum three sets for many projects), title sheet/site plan, and project scope details. Applicable specialist forms (e.g., climate action, waste, erosion/water, school, grading, boundary certification) as required by project type/value. Contractor/owner identity documentation (owner-builder declarations or contractor license/proof where needed).

Permit validity

Permit applications can be deemed abandoned after 365 days. Once issued, the permit is valid for the approved scope, with completion expected within 3 years. Expired permits can trigger reinstatement or reapplication requirements.

Building code

City follows the California Building Standards/California Building Code framework and city-specific adopted standards under municipal code Ch. 18.04; see codes/standards links.

Owner-builder

Homeowner may apply as owner-builder using B-1 and required owner-builder declaration/acknowledgement forms. If an agent files on owner’s behalf, an authorized-agent form is required.

Contractor requirements

Fees

Minimum permit fee

Not published on the public-facing permit walkthrough page; must be confirmed in current Master Fee Schedule.

Permit fee formula

Permit and plan-check charges are established by city fee resolution. Building permit valuation is based on work value (contract price or ICC valuation, whichever is higher). Plan check may include additional charges for revisions/errors requiring re-review.

Reinspection fee

Reinspection fees are assessable for incomplete or non-compliant inspection calls; additional investigation/penalty fees for unpermitted work are also provided for in code.

Penalty (no permit)

Reinspection fees are assessable for incomplete or non-compliant inspection calls; additional investigation/penalty fees for unpermitted work are also provided for in code.

Payment note

Fees are collected as part of submittal/permit issuance workflow and are tied to each submittal and review stage.

Fees change. Verify current amounts at the official fee schedule.

Work That Does NOT Require a Permit

• City notes that most work requires a permit and directs to municipal code exemption section for the definitive list. Refer to CMC 18.04.015 for current municipal-code-specific exemptions. Grading/work disturbance has separate exemptions (for certain small-volume excavation thresholds) in building application materials.

Important: Exemption does not waive other required city, county, or utility approvals. Any exempt scope touching setbacks, occupancy, structure, utilities, or Right-of-Way may still trigger permits or fees.
