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.
How May We Serve You?
Building permits are required for almost all construction related work. This includes plumbing, mechanical, electrical, structural work and even demolition.
