Planning a remodel in Portland? Understanding building codes and permits isn't optional—it's the foundation of your home's legal and structural integrity. After 4 generations of construction in the metro area, ACGI has navigated every regulatory shift from seismic upgrades to ADU zoning.
When is a Permit Required?
1. Structural Modifications
Removing load-bearing walls, adding foundations, or modifying roof structures always requires a permit. This ensures seismic safety and structural load paths remain intact.
2. Major Systems (MEP)
New electrical circuits, plumbing re-routes, or HVAC installations trigger permit requirements to ensure fire safety and hygiene standards meet current Portland code.
3. Decks & ADUs
In Portland, decks higher than 30 inches or larger than 200 sq. ft. require structural permits. Accessory Dwelling Units (ADUs) trigger a complex multi-agency review process.
Portland-Specific Mandates
- Seismic Anchoring: Critical foundation-to-stud connections for earthquake resilience.
- Energy Performance (Title 24): Strict R-value requirements for insulation and window U-factors to reduce carbon footprint.
- Stormwater Management: Projects over 500 sq. ft. often require on-site seepage pits or rain gardens to manage runoff.
At ACGI, we handle 100% of the permitting process as part of our core service. We understand that codes exist to protect your family and your resale value, ensuring your project passes inspection the first time.
