Portland, Oregon Remodeler Local Permit Ordinances and Codes
Portland, Oregon Remodeling and Home Renovation Permit Ordinances
The Authority Having Jurisdiction (AHJ) for building permits in Portland, Oregon, is the Bureau of Development Services (BDS).
Demolition vs. Building Permits
- A distinct demolition permit is generally required when the primary scope of work involves the removal of a structure or a significant portion thereof.
- A standard residential building permit is required for most remodeling and renovation projects that involve alterations, additions, or changes to the existing structure, including interior work, structural modifications, and changes to occupancy. The specific triggers for needing a permit are detailed by the BDS and often depend on the scope and impact of the work on the building's structure, safety, and occupancy.
Converting Non-Living Spaces
- Converting non-living spaces such as basements or garages into habitable areas in Portland typically requires a building permit. This process involves ensuring the renovated space meets current building codes for egress, ventilation, insulation, plumbing, and electrical systems to be considered habitable. Zoning regulations may also apply, particularly concerning minimum room sizes, light, and air requirements.
Fees and Inspection Stages
- Permit fees in Portland are generally based on the project's valuation or scope of work. Specific fee schedules are available through the Bureau of Development Services.
- Inspection stages are critical for all permitted projects. Typically, inspections are required at various milestones, such as foundation, framing, rough-in (electrical, plumbing, mechanical), insulation, and final inspection, to ensure compliance with approved plans and building codes. The exact inspection sequence will be outlined in the permit documentation provided by BDS.

Washington County Building & Safety Division
Washington County Building Services is the Authority Having Jurisdiction (AHJ) for construction, alteration, moving, demolition, repair, and maintenance of buildings and structures within its jurisdiction, including enforcing the State of Oregon Building Code. They provide permitting, plan review, and inspections for both commercial and residential properties in unincorporated Washington County.
Rules for Properties in Unincorporated Areas
Washington County Building Services specifically handles permitting, plan review, and inspections for properties located in unincorporated Washington County. Their regulations apply to construction, alteration, moving, demolition, repair, and maintenance of buildings and structures, with exceptions for those located in public ways.
Specific Permit Triggers for Demolition Work During a Remodel
A demolition permit is generally required prior to demolishing any structure. If the intent of the demolition is to replace the structure with new construction, the demolition permit must be obtained and completed before a structural building permit can be issued. For residential structures, including detached garages and accessory structures over 200 square feet, a demolition permit is required. In some cases, such as demolishing a one- or two-family dwelling, there may be a mandatory notification period before demolition can commence.
Permit Requirements for Altering or Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas typically requires a building permit. Depending on the scope of the work, electrical, plumbing, and mechanical permits may also be necessary. The converted space must meet current building code requirements for living areas, which can include specific standards for ceiling height, emergency egress (windows and stairs), insulation, and ventilation. For example, living spaces generally need a minimum of 70 square feet, with specific ceiling height requirements (often a minimum of 6'8"). Emergency egress windows typically need a minimum clear opening of 5.7 square feet, with specific height and width dimensions, and a sill height no more than 44 inches from the floor. If the existing space does not meet these requirements, upgrades will be necessary, which can sometimes make conversions expensive or impractical. Some jurisdictions may offer alternative standards for conversion projects.

The following statewide building codes and regulations apply universally to all jurisdictions within Oregon:
Oregon Remodeler Legislation, Codes, and Guidelines
Oregon Building Codes for Remodelers and Residential Renovations
In Oregon, the Department of Consumer and Business Services (DCBS), through its Building Codes Division, is responsible for adopting, administering, and enforcing a uniform, statewide building code. This code governs construction and ensures minimum safety standards across the state. Many cities and counties administer and enforce these codes locally.
The state building code is comprised of various specialty codes. For existing buildings and renovations, the primary code is the 2021 Oregon Existing Building Code, which is based on the 2018 International Existing Building Code (IEBC) with Oregon-specific amendments. Other relevant codes include the Oregon Residential Specialty Code (ORSC) and the Oregon Structural Specialty Code (OSSC).
Generally, permits and plan review are required for remodels that involve structural changes, the creation of habitable space, alterations to openings, or modifications to electrical, plumbing, or mechanical systems. Cosmetic work, such as painting, replacing cabinets, or installing new flooring, is typically exempt from permits, provided it does not affect the structure or systems. However, even exempt work must comply with local zoning and code requirements.
Converting attics or basements into habitable living spaces is considered a structural alteration and will require permits and inspections.
Demolition guidelines vary by locality, but generally involve specific notification periods for property owners and may require deconstruction for older structures. For instance, some local ordinances may require a 15-day notice before demolition begins and specify procedures for debris removal and site restoration.
Recent legislative changes in 2024 and 2025 aim to streamline permitting processes for renovations. For example, municipalities over 15,000 in population may be prohibited from requiring frontage improvements as a condition for altering existing buildings, provided certain criteria are met regarding square footage, alteration cost, and occupancy classification.
