In this 2026 update, TerraFirma Foundation Systems’ foundation and structural specialists explain what homeowners in Oregon need to know about permits, inspections, and building codes. This guide reflects current International Residential Code (IRC) standards, regional regulations, and practical insights from decades of experience working with local jurisdictions across the Pacific Northwest.
When planning a home renovation or construction project in Oregon, whether in Portland, Albany, Eugene, or growing communities like Bend and Beaverton, permits and inspections are vital to ensuring that the work is completed safely and up to code. While the process of obtaining permits can sometimes feel frustrating, time-consuming, and expensive, homeowners need to understand how to navigate it properly.
Why Building Permits and Inspections Are Required for Repairs
Permits and inspections exist to protect you as a homeowner. They ensure that any construction work being done complies with the International Residential Code (IRC), a set of minimum safety standards for home construction. These requirements are enforced consistently across Oregon, from coastal cities like Astoria and Newport to inland areas such as Gresham and Hillsboro. A local building inspector will then review the project to ensure no shortcuts were taken, providing you with peace of mind that your home is safe and secure.
Whether you’re updating your foundation, repairing a concrete slab, or undertaking structural renovations, completing the work according to the code also helps avoid future complications. For example, non-permitted work can cause problems when selling your home or during insurance claims if damage occurs.
Permits for foundation-related work in Oregon are governed at the state level by the Oregon Building Codes Division, but they are enforced locally by city and county building departments. For most foundation repair projects, such as underpinning, pier installation, or structural stabilization, a structural permit is typically required because the work affects the load-bearing capacity of the home. In cities like Portland and Eugene, this often includes submitting engineered plans stamped by a licensed structural engineer, followed by inspections at key stages to ensure compliance with the Oregon Residential Specialty Code (ORSC).
How Building Codes Shape Today’s Permit Requirements
Building codes in the U.S. originated in the early 20th century to set construction standards for homes and buildings. Historically, there were three main organizations responsible for developing these codes:
- Building Officials Code Administrators (BOCA) on the East Coast and Midwest.
- Southern Building Code Congress International (SBCCI) for the Southeast.
- International Conference of Building Officials (ICBO), which covered the West Coast and Midwest, including Oregon.
In 1994, these organizations merged to create the International Code Council (ICC). Today, the ICC publishes the IRC, the code used for residential construction across the U.S. Municipalities in Oregon rely on this code to establish local regulations.
Concrete lifting or slab levelling, such as polyurethane injection or mudjacking, may not always require a permit if it is considered non-structural and does not alter the original design of the home. However, in many Oregon jurisdictions, including Salem and Gresham, permits may still be required if the work impacts structural elements, foundation performance, or site drainage. For example, lifting a slab that supports a foundation wall or correcting a settlement that affects framing alignment can trigger permitting requirements. Because these determinations vary locally, homeowners should always confirm requirements with their city or county before beginning work.

Why a Contractor Might Not Pull Permits (and Why It Matters)
If a contractor fails to obtain a permit for your project, it’s a red flag. Here are common reasons why contractors might skip this step and why it should concern you:
1. Honest Mistakes
In some cases, a contractor may simply forget to file the necessary paperwork. However, this “honest mistake” can create serious issues for homeowners. Non-permitted work can delay the sale of your home and lead to difficulties with insurance companies, especially if the work doesn’t meet minimum safety standards. Additionally, it could reflect poorly on the contractor’s attention to detail.
2. Unfamiliar with Updated Codes
Building codes change periodically. A competent contractor should stay informed about these updates, especially in areas like the Pacific Northwest, where seismic activity and weather conditions influence construction standards. A contractor who doesn’t know the current codes might not be equipped to handle your project.
3. Shady Practice
Some contractors deliberately avoid permits to cut costs or because they lack the necessary skills to meet code requirements. This can result in substandard work that compromises the safety of your home. Always choose a contractor who is transparent about the permitting process and committed to following the rules.
4. No Code Exists
In certain cases, there might not be a specific code for the type of work being performed. For example, some foundation repair techniques or niche projects might not have an exact code. However, this doesn’t mean that the project shouldn’t be done to a high standard. Always insist that your contractor uses proper engineering principles and can demonstrate their expertise in specialized areas of construction.
Basement waterproofing projects can fall into a grey area depending on the scope of work. Interior systems, such as drainage channels or sump pump installations, often do not require permits if they don’t alter structural or plumbing systems significantly. However, exterior waterproofing, excavation, or drainage improvements may require permits if the work affects footings, retaining walls, or stormwater flow. In coastal and high-moisture areas like Astoria and Newport, additional oversight may apply due to soil conditions and groundwater management requirements.
Foundation Repair Warranties That Protect Your Investment
In addition to permitting, TerraFirma backs its work and materials with extensive warranties designed to protect homeowners long after the project is complete. These warranties reflect a commitment to quality workmanship and durable repair solutions, giving homeowners added confidence that their foundation repairs are built to perform over time. By combining code-compliant work with long-term warranty protection, TerraFirma helps ensure your investment is protected.
Seismic retrofitting is one of the most regulated types of foundation work in Oregon. Projects such as installing anchor bolts, reinforcing cripple walls, or adding shear walls almost always require permits because they directly impact structural safety. In areas like Portland and across the Willamette Valley, these upgrades often require engineered plans and multiple inspections to verify proper installation. Permitting ensures that seismic improvements meet strict fastening and load transfer requirements designed to improve a home’s performance during an earthquake.
Who Is Responsible for Pulling Permits, Homeowner or Contractor?
Ultimately, the responsibility for obtaining the necessary permits lies with the homeowner. If your contractor skips this step, you could end up facing the consequences, including fines, penalties, or even being forced to undo the work. Don’t hesitate to ask questions and ensure that your contractor is complying with all local codes.
