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.

Important Note: To protect the health of inspectors, contractors, occupants and the construction industry at-large, BDS inspectors may decline or discontinue an inspection if they observe work sites failing to comply with applicable COVID-19 public health guidance. These requirements include maintaining at least 6-feet of physical distance between people whenever possible, and wearing face covers when interacting with others. Please help ensure BDS can continue to perform inspections for your projects in a timely manner by following the public health guidance that applies to your work sites.

More information about COVID-19 public health guidance for workplaces and contractors is available from the Oregon Health Authority and Oregon OSHA. If you have questions about BDS practices, please contact:
