Residential Inspections

Residential inspections are required for one and two family dwellings, including duplexes and two unit townhouses. Types of inspections include: structural, mechanical, electrical and plumbing permit inspections. Other inspections include: electrical safety inspections for the Multnomah County Adult Care Program, ADU (Accessory Dwelling Unit) inspections, code evaluation inspections, manufactured home inspections and special inspections.

The 1 & 2 Family Inspection Section is also referred to as "Combination Inspections" because residential BDS inspectors are trained to inspect all aspects of the project. This saves homeowners, contractors, and the City time, money, and energy in providing inspection services to you.

Once your building permit is issued, erosion control measures must be installed, inspected and approved, prior to beginning any further ground disturbing activities.

Residential Electrical Inspections

Residential electrical permits require three inspections: rough-in, service and final.

Residential Mechanical Inspections

Mechanical permits are required for work on the heating, cooling or ventilation systems in a single family home or duplex.

Residential Plumbing Inspections

All piping (water, sewer, storm water or vent system) must be tested (typically with water) and exposed for inspection prior to burial or covering with floor, wall or ceiling coverings.

Residential Structural Inspections

Whether you are just remodeling a small room or building a new home, these elements need to be inspected before they are covered in any way, or prior to pouring any concrete.

Special Inspections

Special inspections are required to monitor certain critical structural materials requiring the attention of professionals with highly specialized skills and qualifications.

Erosion Control Inspections

Erosion Control inspectors inspect site development permits.
