Permits to demolish buildings or portions of buildings must also be obtained from the Building Safety Division before demolition begins. A building permit may also be required when the use classification of a building or a building space changes, for example, from an office use to a retail business use or from a warehouse use to a retail business use, even when there is limited or no remodeling of the building or space.

Construction work also includes installation or replacement of mechanical/HVAC equipment (such as a furnace or central air conditioning unit), electrical wiring and equipment (such as an electrical panel box or a new electrical circuit), and plumbing piping and equipment (such as a water heater, water or gas supply line, or sewer service line).

A building permit must be obtained from the Development Services Building Safety Division for nearly all types of new building construction, additions, remodeling or repair work prior to start of construction.
