Salem Siding Guide: Permits, Historic Homes, West Salem

In Salem, replacing or repairing siding on its own does not need a building permit unless the wall has to be fire-resistive. A permit is required once the sheathing behind the siding is repaired or replaced, and when T1-11 siding that doubles as structural sheathing is replaced, and the city lists dry rot repair among work that always needs one. On a historic property, replacing siding with a different type, style or material also needs the city’s historic design review. Beyond the rules, the most useful thing to know about a Salem house is when it was built, because that points to the siding problems worth checking first. Tell us about the house and we will follow up about a siding quote.

Permits and historic review in Salem

Two city pages set the permit line: the guidance on work exempt from permits exempts siding-only work and requires a permit for sheathing and structural T1-11, and the page on whether you need a building permit lists dry rot repair among work that always needs one. The owner is responsible for getting required permits, so agree in writing who applies. Salem’s siding permit rules set out both pages, what they mean for rot and window work, and what changes in Keizer and the smaller towns. Historic review is a separate step, covered below.

A Salem address is not always the City of Salem

A Salem mailing address does not settle which office issues the permit. Some neighborhoods with Salem addresses sit outside city limits, including the unincorporated communities the Census Bureau counts as Hayesville and Four Corners. Marion County Building Inspection reviews construction in unincorporated parts of the county, so a house there goes to the county rather than the city. If you are not sure which side of the line a house is on, check the property’s tax record or ask the city’s permit counter before any work that goes past the siding.

How does historic design review work for siding?

Salem has more than 150 individually listed historic properties and four National Register historic districts: the Gaiety Hill/Bush’s Pasture Park Residential District, the Court-Chemeketa Historic District, the Downtown Commercial Core and the Oregon State Hospital. Exterior changes to those buildings go through historic design review, and the city names replacing siding with a different type, style or material as one of the changes that needs it. Ordinary maintenance and repair, such as painting, does not.

Review comes in three classes, according to the city:

• Class 1 minor review, decided by staff, with most decisions issued within 30 days of a complete application.
• Class 2 minor review, which adds a 14-day public comment period, with most decisions within 45 days.
• Class 3 major review, decided by the Historic Landmarks Commission after a public hearing, with most decisions within 60 days.

State law allows up to 120 days once an application is complete. Applications describe the materials to be used, siding included, with photos and drawings of the affected walls. If you are planning a change of material on a historic house, build that time in before booking the work. To check a property’s status, use the city’s Salem Historic Buildings map or ask its historic preservation staff.

The practical upshot for siding: a like-for-like repair of wood siding on a historic house stays outside review, while a switch to fiber cement or vinyl does not. Cedar and wood siding covers repairing older wood siding piece by piece.

When were Salem’s houses built?

The median home in Salem was built in 1980, and 55.9% of homes are owner-occupied. Behind that median is a spread that matters for siding. According to the Census Bureau’s American Community Survey (2020-2024 five-year estimates, table B25034):

• About half of Salem’s homes were built before 1980. That includes nearly 9% built in 1939 or earlier.
• The 1970s were the biggest single decade, at about 17.5% of today’s homes.
• About a quarter were built from 1980 through 1999, the years that overlap the hardboard and OSB siding class actions.
• About a quarter were built in 2000 or later.

Those shares are for housing units of every kind, apartments included, and about 58% of Salem’s homes are single-family detached houses. Each era brings its own list of things to check.

Houses built before 1978

Paint applied before 1978 may contain lead. On a pre-1978 house, a contractor whose work disturbs 20 square feet or more of painted exterior needs a Construction Contractors Board lead-based paint renovation license and has to work lead-safe, under rules Oregon runs through the CCB and the Oregon Health Authority. On houses this age, the siding may also be a later layer over the original, and the paint history on wood trim and sills is often long. Avoid scraping or sanding large areas yourself.

Houses sided from 1980 to the late 1990s

The Masonite hardboard siding settlement covered siding installed from 1980 through January 1998, and the LP Inner-Seal OSB settlement covered siding installed before 1996. Both are closed to claims. On a Salem house built or re-sided in those years, swelling at the lower edges of lap boards is the failure to look for first; see swelling hardboard or OSB siding. Grooved plywood panels from any era can peel apart at the bottom edge; see T1-11 siding damage.

Houses built since 2000

Newer siding is less likely to be a discontinued product, so repairs are easier to match. Whatever the product, the details around it still decide how it holds up: flashing at windows and roof-to-wall corners, the water-resistive barrier, and each maker’s clearances from soil and roofs. Staining below a roof edge on a newer house is still worth a look; siding repair explains why water gets behind siding.

Salem’s areas and their housing

Housing age varies a lot across the city. The figures below are Census ACS 2020-2024 estimates for each ZIP code area (table B25034). ZIP code areas do not follow city limits, so each one includes some houses outside the city, and every estimate carries a margin of error.

Central Salem (97301)

The oldest housing of any Salem ZIP code: a median build year of 1970, with about 19% of homes built in 1939 or earlier and roughly 70% built before 1980. It is also the most rented, with 42.8% of homes owner-occupied. Expect wood lap siding with a long paint history, pre-1978 lead rules on most jobs, and, near the historic districts, design review before any change of material. If you own a rental here, the request form has an option for owners of rental houses.

South-central Salem (97302)

A median build year of 1973. The 1950s and 1960s together account for about 31% of homes, the largest mid-century share of any Salem ZIP code, and about 64% were built before 1980. A mid-century house may have been re-sided at least once, so ask whether what you see is original or a later layer before assuming what is underneath. Lead-safe rules apply to most of this housing.

South Salem (97306)

The newest housing in the city on the median, 1995. The 1990s are the largest decade, at about 24% of homes, and about 38% were built in 2000 or later. Owner-occupancy is high, at 69.3%. A house here built in the early to mid-1990s falls inside the settlement windows above, so check lap siding for swollen lower edges. Newer houses mostly need repairs matched to a product that is still sold.

Northeast Salem (97305)

A median build year of 1986, with the 1970s the largest decade at about 25% and the 1980s and 1990s close behind. Northeast of the city center, outside city limits, the Census Bureau’s Hayesville community has a median build year of 1980, with 38% of its homes from the 1970s. Houses from the 1980s and 1990s are the ones to check for hardboard and OSB siding, and a house outside city limits takes its permits to Marion County.

East Salem (97317)

A median build year of 1978, with a third of homes built in the 1970s, the largest share of any Salem ZIP code for that decade, and the highest owner-occupancy, at 70.8%. East of the city center, the unincorporated Four Corners community has a median build year of 1975. On houses from the late 1970s, the 1978 lead-paint line matters: the year a house was built decides whether lead-safe rules apply.

North Salem (97303)

North Salem shares ZIP code 97303 with Keizer, which makes up most of it. Requests from 97303 are accepted here; the Keizer page covers the Keizer side.

Siding in West Salem

West Salem (ZIP code 97304) sits across the Willamette River in Polk County, but it has been part of the City of Salem since its residents voted to join in 1949. The City of Salem’s permit guidance and historic review rules apply there in full, so a West Salem siding job answers to the city, not to Polk County. Its housing is younger than central Salem’s, with a median build year of 1989 and the 2000s as the largest decade, and 71% of its homes are single-family detached houses, the highest share of any Salem ZIP code. A West Salem house built or re-sided between 1980 and early 1998 falls inside the hardboard settlement window above, so check lap siding for swollen lower edges. Neighboring Polk County towns are different: Dallas runs its own building division, and Monmouth and Independence have their own building departments.

What does siding work cost in Salem?

No official price list exists for Salem, and this site publishes only figures it can source. The siding cost page shows each one with its source and checked date:

• Replacement: the Remodeling Cost vs. Value Report’s average cost for replacing 1,250 square feet of siding with fiber cement or with vinyl, for the Pacific region (2025 report) and for Albany, Oregon (2024 report). Albany, about 25 miles south, is the report’s closest market to Salem, and there vinyl came in above fiber cement, the reverse of the regional figures.
• Repair: HomeGuide’s national range per square foot of repaired wall.
• Removal: HomeGuide’s national range for taking off and disposing of old siding, which a replacement quote may list separately.

Salem-specific costs sit on top of those: a permit and inspection when sheathing or rot is repaired, lead-safe setup on a pre-1978 house, and time for historic review on a listed property. The page’s calculator estimates repair and removal for your own wall area.

Salem weather and siding

NOAA’s 1991-2020 normals for Salem put roughly six to seven inches of rain in each of November, December and January, and about 3.35 inches across June through September combined. That dry stretch is the easiest time for painting and finishing work, and the time to schedule a job that opens up walls.

Two other events show up on Salem siding. The city hit 117°F on June 28, 2021, its hottest day on record, a hard test for vinyl that was hung too tight. And ice storms bring down limbs: a Salem Public Works analysis found the city lost 17.6% of its tree canopy between August 2020 and May 2021, mostly to the February 2021 ice storm, AP reported via OPB. Limb damage to an otherwise sound wall is a siding repair, not a replacement, and storm damage and insurance covers what a homeowners policy usually pays for.
