Building Division

The Building Division serves Hayward's residents and business community by ensuring that all buildings in the City are safe. We do this by reviewing preliminary drawings for code compliance and verifying quality of work during construction.


  • Maintain the highest level of public safety and customer service in the administration of building construction code enforcement
  • Provide City of Hayward residents with a safe environment to live, work, learn
  • Enforce building codes to protect people from the hazards of unsafe construction.

The City of Hayward is considering a new permit software system.  Our goal is to enhance customer service by making the overall process more efficient and intuitive. As a valued customer, we would love to get your feedback on how some of these proposed changes may improve your experience with plan review, permit issuance and inspections.
