What Permits Are Required for a Complete House Removal in Portland?
If you are planning to clear a lot for a new build or remove a hazardous structure, you quickly realize that a "complete house removal" is about much more than just a wrecking ball. In the Portland Metro area, the permit process is one of the most rigorous in the country.
At OJB Solutions, we specialize in being the "One Team" that handles both the heavy machinery and the heavy paperwork. Here is exactly what you need to know about the permits required for residential demolition in Multnomah, Clackamas, Washington, and Clark counties.
1. The Residential Demolition Permit (The Big One)
Whether you are in Portland, Beaverton, or Vancouver, you cannot remove a structure that required a permit to build without first obtaining a Demolition Permit.
Portland (City of): You need a separate permit for each structure. If you’re removing a house and a detached garage, that’s two permits.
Demolition Delay Ordinance: In many Portland neighborhoods, there is a mandatory 35-day delay for residential demolitions. This gives the community time to propose alternatives to demolition.
The Notification Rule: You are often required to mail notices to neighbors within 150 feet and post a "Hotline" sign on the property at least 5 days before work begins.
2. Asbestos & Lead-Based Paint Requirements
Before a permit is even issued, you must address environmental hazards. This is where most DIY projects hit a wall.
Asbestos Survey: Oregon DEQ and Washington L&I require an asbestos survey by a licensed inspector for almost all residential demolitions. If asbestos is found, it must be abated by a certified professional before the "knock-down" begins.
Portland’s Lead Dust Rule: If the home was built before 1978, Portland requires specific lead-based paint inspections (#205 inspections). This includes "wet-wet-wet" methods (spraying water during the demo) to prevent lead dust from drifting into the neighbors' yards.
3. Sewer and Utility Disconnect Permits
You can't just tear a house out of the ground; you have to safely "sever" it from the city's infrastructure.
Sewer Cap Permit: You must obtain a permit to disconnect and cap the private sewer line. A city inspector must verify the cap before it is covered with dirt.
Utility Kill-Letters: Most jurisdictions require "kill-letters" from the electric, gas, and water companies proving that services have been safely decommissioned.
4. The Portland Deconstruction Ordinance
If your house was built in 1940 or earlier, or is a designated historic resource, you may not be allowed to "demolish" it at all.
Certified Deconstruction: You are required to hire a Certified Deconstruction Contractor to take the house apart by hand to salvage materials.
OJB Solutions Note: We help property managers navigate these requirements to ensure you stay compliant with the Bureau of Planning and Sustainability (BPS).
5. Erosion and Sediment Control (Site Stabilization)
Once the house is gone, you are left with a hole in the ground. The city requires a #210 Site Stabilization Inspection.
You must prove that you’ve installed silt fences or straw wattles to prevent mud from washing into the city’s storm drains during our famous Oregon rains.
Frequently Asked Questions
Q: How much does a demolition permit cost in Portland?
A: Fees vary by the value of the project and the specific city, but typically range from $600 to $1,500+ when you include the various inspection and environmental fees.
Q: Can I pull the demolition permit myself?
A: While homeowners can pull permits, it is highly recommended to have your contractor do it. This ensures the CCB license and insurance are correctly tied to the project, protecting you from liability.
Q: What happens if I demolish a house without a permit?
A: In Clackamas and Multnomah counties, "Investigation Fees" can be double or triple the permit cost, and you may be assessed a monthly administrative compliance fee (often $100+) until the violation is resolved.
