Eugene, Oregon Remodeler Local Permit Ordinances and Codes

Eugene, Oregon Municipal Permit Ordinances for Remodelers and Home Renovations

The City of Eugene's Planning and Development Department, specifically the Building and Permit Services division, acts as the Authority Having Jurisdiction (AHJ) for building permits and renovations within the city.

Demolition Permits vs. Residential Building Permits

A demolition permit is required for the deliberate destruction of an entire building or a significant portion thereof.
If a building required a permit for its construction, it will also require a demolition permit for its removal. Structures that were exempt from needing a building permit do not require a demolition permit.
The removal of only a portion of a building is typically considered an alteration and is permitted as part of a larger project, rather than a standalone demolition permit.
Demolition permits are applied for online through the eBuild system.

Space Alterations: Converting Non-Living Spaces to Habitable Areas

Converting non-living spaces such as basements or garages into habitable areas generally requires a building permit.
Accessory Dwelling Units (ADUs), which can include conversions of existing spaces, are permitted in Eugene, but are subject to specific zoning and design standards.
These standards can include requirements for lot coverage, setbacks, building height, and the number of bedrooms, depending on the zone and whether the ADU is attached or detached.
For example, an attached ADU within the same building as the primary dwelling requires a minimum of 8 feet of common wall or ceiling, and its building square footage cannot exceed 10% of the total lot area or 800 square feet, whichever is smaller.
Conversions of garages are generally not permitted unless the required parking can be legally sited elsewhere on the property.

Fee Nuances and Inspection Stages

Building permit fees are calculated based on various factors, including the project's valuation, type of construction, and intended use.
The city provides tools such as a Fee Estimating Guide, Residential Fee Estimates worksheet, and Plan Check Fee Calculators to help estimate costs.
Permit fees cover the review of construction plans, permit issuance, and project inspections.
Additional fees, such as System Development Charges (SDCs) and Construction Excise Tax (CET), may also apply to development projects.
Projects generally follow a four-step process: Prepare, Apply, Review, and Build.
Permits are typically valid for 360 days from issuance to begin construction, and each inspection extends this period by another 360 days. A one-time extension of 180 days is also possible.
After all inspections are approved, a Certificate of Compliance or Certificate of Occupancy is issued.
Some projects, like interior remodels, first-story additions under 500 sq ft, and garage conversions (not creating a new dwelling unit), may qualify for an "Express Permit" program, which aims for same-day permit issuance.

Because Eugene is located within Lane County, the following broader county regulations may also apply to your project:

Oregon, Lane County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Lane County Building & Safety Division

The Lane County Building Program, part of the Public Works Department, is the Authority Having Jurisdiction for building permits and inspections within the county. They ensure construction complies with the Oregon Residential Specialty Code (ORSC) and other relevant codes for structural integrity and public safety. For general inquiries, their Building Message Line can be reached at (541) 682-4651.

Permit Requirements for Unincorporated Areas

In Oregon, building permits are generally required for most construction projects, including major remodels, additions, and structural changes, to ensure compliance with local zoning laws, building codes, and safety regulations. For properties in unincorporated areas of Lane County, the county's Building Program handles permit issuance and inspections. It's important to note that even if a project is exempt from a building permit, it must still comply with all applicable zoning, land use, and sanitation regulations.

Permit Triggers for Demolition Work During a Remodel

Demolition work during a remodel in Lane County generally requires a permit, especially if it involves the full demolition of a structure or the removal of structural elements like walls, roof sections, or floors. Structures built before 1978 require an asbestos survey before demolition can begin, due to federal EPA NESHAP regulations. Partial demolition that involves removing structural components will likely require a building permit, and structural plans may be needed to show how the remaining structure will be supported. Smaller projects, such as removing a small accessory structure built after 1978 and not in a historic district, may be exempt from a demolition permit, but utility disconnection and proper disposal are still necessary.

Permit Requirements for Converting Non-Living Spaces to Habitable Areas

Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas in Lane County requires a building permit. This process typically involves obtaining electrical, plumbing, and mechanical permits as well, depending on the scope of work. The new living space must comply with current residential and energy code requirements. Specific requirements may include minimum ceiling heights, egress windows, and adequate insulation and ventilation. For example, converting a garage into living space often necessitates providing alternative off-street parking, as the original parking space is being converted. Plans illustrating the proposed work, including floor plans, window and door openings, and locations of safety features like smoke alarms, are required for permit applications.

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.
