Residential Mechanical Inspections

Mechanical permits are required for work on the heating, cooling or ventilation systems in a single family home or duplex. Installing a natural gas line, vent, fuel oil tank or chimney liner for appliances or other equipment is also considered mechanical work.

"Mechanical" includes all HVAC (heating, ventilating, air conditioning). This includes gas piping, ductwork, furnaces, heat pumps or air conditioning condensing units. All of these must be inspected prior to covering them up in the structure of a home, or putting them into service.

Programs & Services

Code Evaluation Inspections
In unusual circumstances, a code evaluation inspection may be paid for and requested. We provide structural, electrical, plumbing and mechanical code evaluation inspections. By authorizing a code evaluation inspection, the applicant agrees to bring up to code everything that is found to be in violation of current code, once the inspection has occurred. Please call (503) 823-7388 to determine if this is an appropriate inspection for your situation.
 
Gas Express Program
The Gas Express Program is a collaboration between NW Natural and the City of Portland Bureau of Development Services (BDS). Contractors who qualify for the program can provide an improved level of service to 1- and 2-family residential customers who are converting their dwelling to natural gas. Basically, if a contractor is participating in the program, a permit for the conversion has been purchased and certain conditions are met, NW Natural can turn the gas on before the BDS inspection takes place.
 
The program is designed for customers who are converting furnaces and water heaters to gas in existing 1- and 2-family residential dwellings. The program does not cover gas installations in new construction, commercial and multi-family structures, room additions or remodels that require a residential building permit. Benefits include:
  • Faster gas turn-on for customers
  • Simplifies the process by eliminating BDS inspection at the time of gas turn-on
  • Fewer trips to the site for NW Natural and BDS employees
To participate in the program, contractors must attend an orientation session and sign the Gas Express Agreement. To obtain an agreement, an orientation schedule or more information about the program, please contact either NW Natural at (503) 220-2372 or BDS at (503) 823-7388.
 
 

Corrections

Work may not be approved for a number of reasons: the inspector may not have access to do the inspection the work may not be complete or there may be code violations. If corrections need to be made, the inspector will note them on the inspection report. Results are entered the day of the completed inspection by 5 p.m. Corrections shall be made prior to requesting reinspection. When requesting a reinspection use the same three digit inspection code.

 
Please note that a reinspection fee may be charged for more than one reinspection for a single issue.
