Siding Contractors in Monmouth, OR: Owners & Landlords

Monmouth was founded as a school town, and it still reads like one. Western Oregon University began there as Monmouth University, and the Census Bureau’s latest estimates make Monmouth the only town covered on this site where renters outnumber owners. That matters for which rules apply: a landlord re-siding a rental built before 1978 has lead-safe obligations an owner working on their own home does not. Permits come from the city’s own Building Department, not Polk County, and a handful of designated landmarks need a historic permit before their siding changes. Owners and landlords can both request a siding quote here, and we will follow up about the work.

Monmouth’s Building Department

The City of Monmouth runs a full-service building department, issuing structural, electrical, mechanical, plumbing and manufactured home placement permits, with its building official at City Hall on Main Street West; most trade permits can also be applied for through Oregon ePermitting. Polk County’s building page lists Monmouth among the cities where the county does not issue building permits.

Monmouth does not publish a list of work exempt from permits, so the state code sets the line. The Oregon Residential Specialty Code exempts “replacement or repair of siding not required to be fire-resistance rated”, and Oregon’s version requires a one-hour fire-resistance rating on an exterior wall less than 3 feet from the lot line. Measure before assuming a side wall near the lot line is exempt. Work behind the siding is the other trigger to ask about: Salem requires a permit to repair sheathing, or to replace T1-11 that is also the structural sheathing, and Monmouth’s Building Department can say how it handles the same work.

The city’s building code page also links the Monmouth Housing Code and a rental unit violation form. New siding, permit or not, still goes over a water-resistive barrier with kickout flashing at roof-to-wall corners and, by default, a drainage gap; do you need a permit to replace siding? explains those rules. A 2026 edition of the state code took effect on October 1, 2026, with a six-month phase-in before it becomes mandatory on April 1, 2027.

Landlords, owners and who needs which license

With more rentals than owner-occupied homes, the most common Monmouth siding question may be who is allowed to do the work. Three different rules apply, and they are easy to mix up:

• The contractor license. Oregon’s contractor law, ORS 701.010(7), exempts a person performing work on property they own, “whether the property is occupied by the owner or not”, unless the work is done as a business with the intent of offering the structure for sale. So a landlord may re-side their own rental. Anyone the landlord pays to do it needs a Construction Contractors Board license, and the CCB lists siding among the work that requires one.
• Lead-safe rules for a landlord. On a house built before 1978, the Oregon Health Authority says property owners and managers who renovate, repair or paint in pre-1978 rental housing must take the initial 8-hour renovation, repair and painting training and get firm certification from OHA. The exemption for doing your own work covers only your own home.
• Lead-safe rules for a contractor. A contractor disturbing 20 square feet or more of painted exterior on a pre-1978 home needs a CCB lead-based paint renovation license. OHA treats disturbing less than 20 square feet of exterior paint as minor repair.

About 39% of Monmouth’s homes predate 1980, so these rules come up on a good share of jobs. If you manage rentals, check the build year before scheduling any scraping, cutting or tear-off.

College-town housing, decade by decade

The American Community Survey’s 2020-2024 five-year estimates (tables B25034 and B25003) put the median Monmouth home at 1993. Only 47.4% of occupied homes are owner-occupied, and only about 54% of homes are single-family detached houses. By decade:

• The 1960s and 1970s: about 31% of homes, the 1960s alone about 14%, the largest 1960s share of any town covered here.
• The 1980s: about 5%. The 1990s: about 18%.
• Since 2000: about 38%, with the 2000s the largest single decade.
• Before 1960: about 8%.

The ZIP code, 97361, takes in the farmland around town, and there owners are a slight majority, about 57%.

The 1960s and 1970s houses are the group to watch. All of them predate the 1978 lead line, and at that age most have been repainted many times and some re-sided. On wood siding and trim of that age, check the bottom courses, the sills and the boards under windows first; dry rot in siding and trim explains what to look for. Houses built or re-sided from 1980 into the late 1990s may carry hardboard (the Masonite settlement covered installs from 1980 through January 1998) or LP Inner-Seal OSB (installs before 1996); both settlements are closed, and swelling hardboard or OSB siding shows what the failure looks like. Newer houses mostly carry siding that is still made, and James Hardie’s ZIP list puts 97361 in its HZ10 zone, as it does Salem.

Monmouth’s historic houses

Monmouth has a seven-member Historic Commission, advisory to the City Council, and the city publishes architectural styles and guidelines for its East Main Street historic neighborhood. The rules for designated landmarks are in chapter 18.160 of the city code:

• A historic alteration permit is required before anyone significantly or materially alters the exterior of a designated landmark, and no building or other permit is issued until it has been.
• Ordinary maintenance and repair are exempt when they do not materially change design, material or outward appearance, and exterior painting is exempt.
• The guidelines favor repair. Deteriorated features should be repaired rather than replaced, and new material should match the old in composition, design, color and texture.
• Designation needs the owner’s consent.

Several Monmouth houses are also on the National Register of Historic Places, including the Craven House on East Main Street (built 1869), the Graves-Fisher-Strong House (1891), the John W. Howell House, the Eleanor Sherman House (1900) and the Burford-Stanley House, built in 1857 and listed in 2022. Its nomination calls it the oldest known building still standing in Monmouth, and notes that both sections are clad in the same 7-inch shiplap fastened with cut nails, with some original weatherboard siding still exposed. That is the kind of material a like-for-like repair keeps; cedar and wood siding covers repairing it board by board.

Repair or replace on a Monmouth house

On a rental between tenants, the pull is to fix only what shows. That works when the damage is a few boards and the sheathing is sound. When the same failure shows on several walls, or the siding is 1980s or 1990s hardboard nobody makes, price a full re-side with new flashing alongside the patch before deciding. Either way, the lead rules above decide how the work is set up on a pre-1978 house. Fiber cement and vinyl are the usual replacement choices, and siding repair covers the repair-or-replace decision in detail.

Published repair and removal figures

No Monmouth prices are published. HomeGuide’s national range for siding repair is $2 to $14 per sq ft of repaired wall, and for removing and disposing of old siding $70 to $200 per square (100 sq ft of wall). As illustrations for a rental, not quotes:

• Patching a 4-by-7-foot area of damaged boards beside a back door, 28 square feet: $56 to $392.
• Stripping the old siding from a small house with 1,000 square feet of wall, 10 squares: $700 to $2,000, before any new siding goes on.

HomeGuide puts the repair spread down to material, extent of damage and location, and notes that removal is often left out of first estimates.

Before a Monmouth quote

• Whether you live in the house or rent it out, and the year it was built.
• If it is a pre-1978 rental, whether you or the contractor will handle the lead-safe setup, and the contractor’s CCB lead-based paint renovation license.
• Whether the house is a designated landmark.
• Whether a wall sits within 3 feet of a property line.

Request a Monmouth siding quote

Use ZIP code 97361 on the quote request form, and say whether the house is a rental. We will follow up about a quote. Whoever quotes the job, the CCB license search shows whether their license, and any lead-based paint renovation license, is active. Independence, less than two miles east, runs its own building department and historic district review, and Dallas and Salem have their own pages.
