What Permits Are Required for a Complete House Removal in Portland?
If you are planning a residential tear-down, you aren’t just moving "junk"—you are navigating a complex legal landscape. In the Portland Metro area, removing a structure is as regulated as building one.
At OJB Solutions, we specialize in being the "One Team" that bridges the gap between demolition and debris removal. To help you plan your timeline, here is the definitive guide to the permits required for house removal in Multnomah, Clackamas, Washington, and Clark Counties.
1. The Residential Demolition Permit
You cannot legally remove any structure that required a permit to build without first obtaining a Demolition Permit.
City of Portland: Requires a separate permit for every structure on the lot. If you are removing a house and a detached garage, you need two permits.
The 35-Day Delay: Most residential demolitions in Portland are subject to a mandatory 35-day delay to allow for neighborhood notification.
Notification Requirements: You must mail notices to neighbors within 150 feet and post a "Hotline" sign on the property at least 5 days before work begins.
2. Environmental Permits: Asbestos & Lead
Before the first machine touches the house, the "invisible" hazards must be cleared. This is where most projects get stalled.
Asbestos Survey (DEQ/WA L&I): All jurisdictions require an asbestos survey by a licensed inspector. If asbestos is found, it must be professionally abated before demolition.
The "Wet-Wet-Wet" Rule (#205 Inspection): For homes built before 1978, Portland requires specific lead-based paint dust control. This involves three stages of wetting the structure during the mechanical "knock-down" to prevent lead dust from drifting onto neighboring properties.
3. Sewer Cap & Utility Disconnect Permits
You must safely "sever" the home from city infrastructure before removal.
Sewer Cap Permit: A permit is required to cap the private sewer line. A city inspector must verify the cap before it is backfilled.
Utility Kill-Letters: You will need official "kill-letters" from the power, gas, and water companies proving that services have been safely decommissioned.
4. The Portland Deconstruction Ordinance
If your home was built in 1940 or earlier, or is in a designated historic district, you may not be allowed to "demolish" it at all.
Mandatory Deconstruction: These homes must be taken apart by hand by a Certified Deconstruction Contractor to salvage materials.
OJB Solutions Expertise: We help property managers identify if their project falls under this ordinance to avoid heavy city fines.
5. Erosion & Site Stabilization (#210 Inspection)
Once the house is gone, the city requires the lot to be stabilized to prevent mud from washing into storm drains.
This involves installing silt fences or straw wattles. The project is not considered "finaled" until the #210 Site Stabilization Inspection is approved.
Frequently Asked Questions
Q: Can I pull my own demolition permit as a homeowner?
A: Yes, but it is risky. When OJB Solutions pulls the permit, our CCB License (#255649) and insurance are tied to the job, protecting you from liability if something goes wrong.
Q: How long does the permit process take?
A: In Portland, expect 6–8 weeks due to the 35-day delay and plan review. In surrounding counties like Clackamas or Washington, it can often be done in 2–3 weeks.
Q: What happens if I demolish without a permit?
A: Cities can charge "Investigation Fees" that are double or triple the permit cost, and they may put a "Stop Work Order" on your new construction project.
The OJB Solutions Advantage
National competitors like College Hunks aren't licensed for demolition work. Local firms like Mayer Construction are great, but they often don't provide the integrated junk hauling and driveway-friendly trailer dumpsters that we do.
Integrated Service: We handle the permit filing, the asbestos coordination, the demolition, and the final sweep-up.
Property Protection: Our rubber-tired trailers won't crack your concrete like heavy steel-wheeled roll-offs.
Local Accountability: We are licensed and insured in both Oregon and Washington.
