Plan Review Services

Plan review is required for additions, remodels, tenant improvements and all new construction. The Building and Safety Department is committed to providing timely and professional review of plans and documents for all building permit applications to assure that the proposed work complies with all state and local codes and requirements.


The review of plans for permit issuance may take place in one of the following ways:

Over-the-Counter (OTC) Plan Review:

  • OTC plan review is limited to projects that are not complex and are small in scope-of-work that can be reviewed within approximately 30 minutes. Such projects include patio covers, minor field revisions and minor residential remodels.
  • OTC Hours: Please call for appointment.

Regular Plan Review: 

Regular plan review is for all projects that require more than approximately 15 minutes to review. Digital plan sets shall be submitted and will be forwarded to appropriate city departments for review and approval. The plans are placed in the queue of each respective city department to be reviewed in the order they were received. Please see the digital review submittal link for more information.
