Contractor insurance on the Oregon Coast.

Basic design wind speed in the Clatsop, Tillamook and Lincoln special wind regions runs 125 to 145 mph with full ocean exposure. Marion County is 92 to 108 mph and Benton County 90 to 107 mph. Because wind pressure scales with the square of velocity, that is close to double the load on the structure (Oregon BCD, Table 1609.3).

Who this page is for

Contractors working Astoria, Seaside, Cannon Beach, Tillamook, Lincoln City, Newport and Florence, across Clatsop, Tillamook and Lincoln counties. If you are a valley contractor thinking about taking coast work, this page is mostly a list of things that will surprise you.

What this page covers. The north and central coast as one market: Astoria, Seaside, Cannon Beach, Tillamook, Lincoln City, Newport and Florence, across Clatsop, Tillamook and Lincoln counties. The south coast around Coos Bay is an industrial port market rather than a resort market and has its own page.

The wind number is the whole story

Start here, because everything structural on the coast follows from it.

Oregon designates parts of the coast as a special wind region with dramatically higher basic design wind speeds than the interior. Under the Structural Specialty Code amendments, for buildings with full ocean exposure:

That is roughly a 40 percent higher design wind speed, and because wind pressure scales with the square of velocity, the load on the building is close to double. It flows into everything: roof-to-wall connections, uplift straps, shear transfer, sheathing nailing patterns, and the pressure ratings on windows and doors.

A valley crew building to valley habits on a coastal job is not slightly out of spec. It is materially under-built, and the failure shows up in the first serious winter storm, which lands it squarely in completed operations.

One practical note from the code itself: sites near the edge of the special wind region have to be verified using the ASCE 7 Hazard Tool rather than assumed from the county. Do not eyeball the boundary.

Corrosion is a code requirement, not a preference

Salt air is not just a durability nuisance on the coast. Oregon's adopted codes carry corrosion-resistance requirements for fasteners and connectors within defined distances of salt water, with the specific requirement depending on the building element, roofing and wall covering fasteners are treated differently from general structural connectors.

Because the thresholds and stainless grades differ by code section, confirm the applicable requirement for your specific assembly with the building official rather than working from a rule of thumb. What matters commercially is simpler: a galvanised connector that is perfectly acceptable in Albany can be a defect on the coast, and the failure appears years later as a corroded hold-down, which is exactly the kind of latent defect that surfaces long after final inspection.

Goal 18 and the January 1, 1977 line

If a client asks you to build shoreline protection, riprap or a seawall, this determines whether the job is even possible.

Statewide Planning Goal 18 is explicit: permits for beachfront protective structures shall be issued only where development existed on January 1, 1977. Development for this purpose means houses, commercial and industrial buildings, and vacant subdivision lots that were physically improved with streets and utilities to the lot.

The practical effect is a hard go or no-go gate. If the property was not developed as of that date, no engineering proposal makes it eligible. Where a permit is possible, the criteria still require minimising visual impact, maintaining beach access, minimising impacts on adjacent property and avoiding long-term public costs.

Shoreline armoring is also actively litigated on the Oregon coast, with conservation groups appealing exception decisions. Treat a shoreline protection job as a land use matter with real timeline risk, not a construction job with a permit attached.

The ocean shore permit nobody budgets enough time for

Work on the ocean shore itself, beach access construction and repair, shoreline protection, dune grading, requires an Ocean Shore Alteration Permit from Oregon Parks and Recreation Department.

OPRD recommends applying six months or more before your intended construction window. Review covers scenic, recreational, safety and natural and cultural resource standards, requires consideration of alternatives, and ties back to Goal 18 and the local comprehensive plan.

There is a separate emergency track for storm and erosion damage, which is worth knowing about before you need it rather than during the week you do.

Tsunami rules, and what they actually restrict

This is widely misunderstood, in both directions.

Oregon has mapped tsunami inundation zones through DOGAMI, and statute has long restricted certain essential facilities and special occupancy structures, hospitals, schools, fire and police stations, in those zones. House Bill 3309 in 2019 removed the outright prohibition for certain categories and moved the siting decision to local jurisdictions.

What matters for most contractors is the scope: these rules target essential and special occupancy facilities, not ordinary houses and small commercial buildings. If you are building a custom home in Lincoln City, the tsunami statute is not what governs your permit. Do not let anyone tell a client otherwise.

What is genuinely relevant is the site conditions the mapping reveals. DOGAMI's hazard viewer stacks tsunami, coastal erosion, liquefaction, soft soils and landslide layers by parcel. Coastal sites fall into liquefaction and soft soil categories more often than inland sites, and that is what triggers geotechnical investigation requirements under the standard code. There is no separate coastal seismic code; there is a much higher likelihood that the standard code sends you to a geotechnical engineer.

Who issues your permit changes town by town

The coast has an unusually fragmented permitting picture. Clatsop County administers building codes for unincorporated areas and handles electrical permits countywide across both unincorporated and incorporated jurisdictions. Tillamook County runs its own building division. Lincoln County issues permits not only for unincorporated areas but on behalf of Depoe Bay, Siletz, Toledo, Waldport and Yachats, which do not run their own building departments, while larger cities like Newport and Lincoln City do.

Confirm the authority for the specific address before you plan a schedule. On this stretch of coast, two towns fifteen minutes apart can be different jurisdictions with different portals.

Business licences and the vacation rental economy

Unlike the valley, most coastal cities do require a local business licence, and several apply it specifically to contractors coming in from outside. Newport requires one for any enterprise operating in city limits beyond a small annual hours threshold. Florence issues a temporary class of licence aimed at contractors based elsewhere, with state CCB registration as a prerequisite. Cannon Beach, Tillamook and Lincoln City each have their own requirement. Check each city you work in rather than assuming a single coastal rule.

The short-term rental economy adds a wrinkle that inland contractors never meet. Coastal cities regulate vacation rentals closely, and in several the rental licence itself is tied to inspection. Lincoln City requires a fire district inspection to renew a short-term rental licence, and Newport ties licensing to inspection and a per-unit endorsement. Cannon Beach's permits do not transfer when a property sells.

For a contractor doing a renovation or a conversion, that means your work is being pointed at a fire marshal or code inspection tied to the owner's rental licence, not just a standard building permit final. Ask what the inspection standard is before you scope the job, because the owner's income depends on passing it.

Questions worth asking before you take coast work

• What is the design wind speed for this exact site, verified rather than assumed from the county?
• Are my connectors and fasteners specified to the coastal corrosion requirement for this assembly?
• If this is shoreline protection, did development exist on the parcel before January 1, 1977?
• Does any part of this work sit on the ocean shore, and have I allowed six months for the OPRD permit?
• Which jurisdiction issues the permit at this address?
• Do I hold the business licence for this specific city?
• Is this a short-term rental, and is the owner's licence renewal tied to an inspection of my work?
