Oregon 90-Day Notice for Demolition or Major Renovation — Landlord Compliance Guide (2026)

Why Oregon’s 90-Day Notice Rule Exists — And Why It Matters for Your Business

In July 2026, Oregon remains one of the strongest tenant-protection states in the nation. The 90-day notice requirement for demolition and major renovation is not a technicality—it’s a statutory protection designed to prevent landlords from using demolition claims as a pretextual reason to remove long-term tenants and raise rents.

Self-managing landlords often assume that if they’re planning legitimate demolition or renovation work, the notice requirement is straightforward. It isn’t. Oregon courts and the Bureau of Labor and Industries (BOLI) take these notices seriously. Tenants’ rights advocates regularly file complaints alleging wrongful termination. If you miss a procedural requirement—even one that seems minor—you lose the eviction, pay the tenant’s attorney fees, and potentially face statutory damages.

This guide walks you through the exact compliance requirements under ORS 90.427(7), including what must be in the notice, how to calculate the 90-day period, what documentation you need to keep, and what happens if you get it wrong.

What ORS 90.427(7) Actually Says — The Statute

Oregon Revised Statute 90.427(7) provides:

“A landlord may terminate a tenancy by notice in writing to the tenant stating the reasons for the termination and the date the tenancy is to terminate. The notice shall be given at least 90 days before the tenancy is to terminate if the reason for the termination is that the landlord intends to demolish the dwelling unit or building or make major repairs that will make the dwelling unit unlivable.”

This statute is narrow, precise, and strictly enforced. Let’s break down what it requires:

The Five Mandatory Elements of a Valid 90-Day Notice

1. Written form — The notice must be in writing. Email, text message, or verbal notice is not sufficient. It must be delivered to the tenant in a manner that creates a dated record of receipt.
2. Statement of reason — You must explicitly state that the reason is either (a) demolition of the dwelling unit or building, or (b) major repairs that will make the dwelling unit unlivable. Vague language like “property improvements” does not satisfy this requirement.
3. Termination date — You must specify the exact date on which the tenancy will end. This date cannot be earlier than 90 days after the tenant receives the notice.
4. Proof of intent and necessity — While not explicitly stated in ORS 90.427(7), Oregon courts require that the landlord have genuinely committed to performing the work and that the work actually requires the unit to be vacated. If you terminate based on claimed “major repairs” and then never perform them, or rent the unit out immediately after the tenant leaves, you’ve committed wrongful eviction.
5. Proper delivery — The notice must be delivered to the tenant in compliance with ORS 90.160, the statute governing notice delivery. See below for delivery methods.

How to Calculate the 90-Day Period — Timing Requirements

One of the most common compliance errors is miscalculating when the 90 days begins and ends. Oregon law is clear: the 90-day period runs from the date the tenant receives the notice, not the date you send it.

Proper Calculation: Three Examples

Scenario	Delivery Date	Earliest Termination Date
Hand-delivered notice	July 15, 2026 (receipt signed)	October 13, 2026 (90 days later)
Certified mail with return receipt	July 18, 2026 (signature on receipt)	October 16, 2026
Email (if permitted by lease)	July 20, 2026 (read receipt or tenant acknowledgment)	October 18, 2026

Critical detail: If you use certified mail and the tenant refuses to sign or is not home, you may need to use an alternative delivery method under ORS 90.160 (posting and mailing). In that case, document everything. The 90 days still runs from the date of posting/mailing, but you need proof that the alternative method was necessary.

Notice Delivery Methods — ORS 90.160 Requirements

ORS 90.427(7) requires notice be given “in writing,” but ORS 90.160 specifies the legal methods of delivering that notice. You must use one of these methods:

Method 1: Personal Delivery

Hand the notice directly to the tenant. Get a signature on a copy, or have a witness sign confirming delivery. This is the safest method because you have immediate proof of receipt.

Method 2: Certified Mail, Return Receipt Requested

Send the notice via USPS certified mail with return receipt. The return receipt card, signed by the tenant or their agent, serves as proof of delivery. File this with your records.

Method 3: First-Class Mail Plus Posting (if tenant is absent or refuses service)

If the tenant refuses certified mail or is not home after reasonable attempts, you may post the notice on the dwelling unit (on the door or main entrance) and mail a copy via first-class mail. Both actions must occur. Document:

• Date and time you posted the notice
• Photograph showing the posted notice
• Date you mailed the copy (keep the mail receipt)
• Any attempts to deliver before posting

Method 4: Email (if permitted by the lease)

If your lease agreement explicitly permits email notice and the tenant has provided an email address, email is acceptable. You must retain:

• The email with time-date stamp
• Proof the tenant read it (read receipt) or acknowledged receipt
• The lease provision authorizing email notice

Do not rely solely on email without a backup method or explicit lease authorization. If a dispute arises, the burden is on you to prove the tenant actually received it.

What Must Be Included in the Notice — Specific Language and Attachments

Oregon courts strictly construe notice requirements. Your notice must contain all of the following information, clearly stated:

Required Content Checklist

What NOT to Include

Do not include language that undermines your stated reason:

• No references to high rent or the tenant’s income level
• No statements like “we plan to modernize the unit” (this is not demolition or major repair)
• No indication that the tenant can “negotiate” or pay money to stay
• No alternative lease terms or rent increases in the same notice

Any of these statements could be used by the tenant’s attorney as evidence that the stated reason is pretextual—a cover story for removing a tenant you simply want to replace.

Proof That the Work Actually Happens — Avoiding Wrongful Eviction Claims

Oregon courts have consistently held that if a landlord terminates a tenancy for demolition or major repair and then does not perform that work (or rents the unit to a new tenant shortly after), the landlord has committed wrongful eviction. The tenant can sue for damages, attorney fees, and potentially statutory penalties.

Case authority: While ORS 90.427(7) does not explicitly require proof that work was performed, case law and BOLI guidance make clear that landlords have a duty of good faith. If you claim major repairs are necessary and then abandon those repairs or re-rent the unit within a short period, you expose yourself to significant liability.

Documentation Strategy: Protect Yourself

Before you issue the notice, gather and keep:

• Written contractor estimate or quote — dated, specific to the unit/building, detailing the scope and timeline of work
• Building inspector report or code violation notice — if the work is required by law, attach a copy
• Photographs of the existing condition — showing why the work is necessary (structural damage, hazardous materials, etc.)
• Email correspondence with contractors — showing you have sought quotes or hired someone to perform the work
• Permit applications — if required by your city, file permits before or immediately after issuing the notice
• Work timeline document — stating when work will begin and end

After the tenant vacates, keep records of:

• Invoices and payments to contractors
• Photos of work in progress
• Completion certificates or sign-offs from inspectors
• The date the work actually finished
• If you re-rent the unit, documentation showing the unit was vacant and under renovation during the interim period (do not immediately list it on rental sites)

The burden is on you, as the landlord, to demonstrate good faith. If a tenant sues and claims the termination was wrongful, the judge will examine whether the work was actually necessary and whether you actually performed it. Lacking documentation, the tenant wins.

Common Compliance Mistakes — And How to Avoid Them

Mistake 1: Confusing “Major Repairs” with Routine Maintenance

The error: Issuing a 90-day notice claiming “major repairs” when the work is actually cosmetic upgrades (paint, flooring, fixtures).

Why it fails: Oregon courts define “major repairs that will make the dwelling unit unlivable” narrowly. Cosmetic improvements do not qualify. The tenant remains. You cannot evict. You face wrongful eviction liability.

What qualifies as major repair: Structural repairs, electrical system overhaul, plumbing replacement, asbestos abatement, mold remediation requiring unit abandonment, heating system replacement, roof replacement, foundation repair, hazardous material removal.

What does NOT qualify: New appliances, updated fixtures, fresh paint, new flooring (unless the unit is unsafe without it), kitchen upgrades.

Mistake 2: Issuing the Notice Without a Specific Termination Date

The error: “The tenancy will terminate 90 days from the date of this notice” instead of “The tenancy will terminate on October 13, 2026.”

Why it fails: Oregon requires that the notice state “the date the tenancy is to terminate.” A vague reference to “90 days from now” is unenforceable. A tenant could argue the notice is invalid, and a court would likely agree.

Fix: Always calculate the exact date. If you deliver the notice on July 15, write “October 13, 2026” in the notice.

Mistake 3: Trying to Combine the 90-Day Notice with a Standard 30-Day Termination

The error: Sending both a 90-day demolition notice and a 30-day month-to-month termination notice to cover your bases.

Why it fails: If the notices conflict, a court will void both or enforce whichever is most favorable to the tenant. Sending conflicting notices suggests you are unsure of your legal grounds, which strengthens the tenant’s argument that the demolition claim is pretextual.

Fix: Issue one notice only. If you are genuinely demolishing or renovating, use the 90-day notice under ORS 90.427(7). If you are simply ending a month-to-month tenancy, use the 30-day notice under ORS 90.427(3).

Mistake 4: Issuing the Notice Via Regular Mail Without Proof of Receipt

The error: Dropping the notice in the mail without certified mail, return receipt, or documented hand delivery.

Why it fails: You cannot prove the tenant received the notice. If the tenant claims they never got it and you try to evict, the judge will find that notice was improper. The eviction fails. You must start over—if you can.

Fix: Use certified mail with return receipt or hand-deliver with a signature. Document everything.

Mistake 5: Continuing to Collect Rent After the Termination Date Passes

The error: The 90 days expire. The tenant is still in the unit. You accept rent for the next month instead of filing for eviction.

Why it fails: Accepting rent after the termination date renews the tenancy under Oregon law. You have waived the notice. You must start the entire process over. Your 90-day notice is dead.

Fix: If the tenant has not vacated by the termination date, do not accept rent. File for eviction immediately. The grounds are “failure to vacate after notice to terminate.” (This is a statutory eviction, not “failure to pay rent.”)

Step-by-Step Compliance Process: From Planning to Eviction

Phase 1: Pre-Notice Planning (Weeks 1-4)

1. Confirm that the work genuinely qualifies as demolition or major repair. If unsure, consult a local building inspector or attorney.
2. Obtain contractor estimates or quotes. Keep copies.
3. File any required building permits if the work is substantial.
4. Take photographs documenting the current condition and the need for work.
5. Determine the earliest date you want the unit vacated (must be at least 90 days from notice delivery).
6. Draft the notice. Include all required language (see the checklist above).
7. Have an attorney or compliance tool review the draft. Do not skip this step.

Phase 2: Notice Delivery (Week 5)

1. Deliver the notice to the tenant using certified mail with return receipt, or hand-deliver it. Do not use regular mail.
2. If you hand-deliver, get a signature from the tenant or a witness.
3. If the tenant refuses certified mail or is absent, post the notice on the unit door and mail a copy first-class. Photograph the posting.
4. Log the delivery date and method in your records.
5. File all delivery proof (return receipt, signature, photographs) in a secure location. You will need these if the tenant disputes the notice later.

Phase 3: The 90-Day Waiting Period (Weeks 5-18)

1. Do not accept rent from the tenant for any period beyond the termination date. If rent is due before the termination date, accept it; after the date, refuse it.
2. Maintain communication with the tenant about their move-out date. Provide a forwarding address for their security deposit.
3. Begin scheduling contractors and finalizing work plans. Do not announce that you will re-rent the unit immediately after move-out.
4. Monitor whether the tenant is vacating. If they indicate they will not leave, prepare for eviction action.

Phase 4: Eviction (If Necessary, Starting Week 18)

1. If the tenant has not vacated by the termination date, file a “failure to vacate” eviction action in the local district court.
2. Attach a copy of the 90-day notice and proof of delivery to the complaint.
3. Serve the tenant with the eviction complaint according to Oregon rules (typically 10 days before trial).
4. Appear at trial. Testify about the notice, the termination date, and the tenant’s failure to vacate.
5. If you win, the judge will issue an eviction judgment. The tenant has 3 days to vacate before the sheriff enforces the eviction.

Phase 5: Post-Vacate Obligations

1. Begin the contracted work immediately or within a reasonable timeframe. If you delay, you strengthen the tenant’s argument that the demolition claim was false.
2. Keep detailed records of all work performed: invoices, receipts, photos, contractor agreements.
3. Do not re-rent the unit until the work is substantially complete and the unit is legally habitable.
4. If you re-rent after a significant delay, document that the unit was under renovation during the interim period.
5. Return the tenant’s security deposit within 31 days of move-out, with an itemized list of any deductions for damage (not for work to be performed).

What Happens If You Violate ORS 90.427(7) — Penalties and Consequences

Civil Liability

Wrongful eviction damages: If a court finds you violated the 90-day notice requirement or issued the notice in bad faith (pretextually), the tenant can sue you for:

• Actual damages (relocation costs, increased rent elsewhere, moving expenses)
• Lost wages if the tenant had to take time off work to move
• Emotional distress (in some cases)
• Attorney fees and court costs (the tenant recovers these from you)
• In cases of clear bad faith, punitive damages (designed to punish, not just compensate)

Typical damage award range: $5,000 to $25,000+ depending on the severity of the violation and the tenant’s circumstances. If your violation was egregious (e.g., you issued the notice without 90 days’ notice, or you never performed the claimed work and immediately re-rented), damages can exceed $50,000.

Statutory Penalties

Under ORS 90.992, a landlord who violates the Oregon Residential Tenancies Act (of which ORS 90.427 is part) is liable to the tenant for:

• The tenant’s actual damages, plus
• Civil penalty of $50 to $300 per day of violation (depending on the specific violation)
• Attorney fees and costs

Example: If you issue a 70-day notice instead of a 90-day notice and the tenant sues, the civil penalty could be $50–$300 per day for each day the notice was short (20 days × $50–$300 = $1,000–$6,000 minimum). Add in the tenant’s actual moving costs, the tenant’s attorney fees, and your own legal costs.

Criminal Consequences (Rare but Possible)

Oregon law allows for criminal prosecution of landlords who intentionally violate tenant rights in egregious circumstances. ORS 90.992 also provides for criminal liability if violations are willful and repeated. This is uncommon but does occur, particularly in cases involving multiple tenants or a pattern of unlawful conduct.

Eviction Case Dismissal

If you file for eviction after violating the 90-day notice requirement, the eviction case will be dismissed. You cannot recover possession of the unit. You must begin again with a proper notice if you still wish to pursue eviction (though your credibility with the court is now damaged).

How Compliance Tools Protect You — Reducing Risk

Managing the 90-day notice requirement manually—tracking delivery dates, calculating the termination date, maintaining proof, documenting work—leaves room for error. Small mistakes are expensive.

A compliance engine that knows Oregon law can:

• Pre-populate notices with correct statutory language and dates
• Calculate the 90-day period automatically and ensure the termination date complies with the law
• Attach proof of delivery to your notice file automatically
• Alert you if the tenant pays rent after the termination date (preventing accidental waiver)
• Generate reminders at day 85 to prepare for potential eviction if the tenant has not indicated move-out
• Archive all documentation for future reference or dispute

Demolition vs. Major Renovation — When Does Each Apply?

ORS 90.427(7) covers two grounds for issuing a 90-day notice: (1) demolition, and (2) major repairs. Courts distinguish between them, and your choice matters.

Demolition Notices

What qualifies: The landlord intends to demolish the entire building or the specific dwelling unit where the tenant resides.

When to use it: The building or unit will cease to exist. The owner plans to rebuild, repurpose the land, or remove the structure for safety or code reasons.

Standard of review: Courts apply moderate scrutiny. If you claim demolition, you should have permit applications or architectural plans showing the demolition is genuine. If you later sell the building without demolishing it, you face wrongful eviction liability.

Major Renovation Notices

What qualifies: Work is substantial enough that the dwelling unit is rendered unlivable during the repair period. The tenant cannot safely or legally occupy the unit while work proceeds.

When to use it: Structural repairs, system replacements (electrical, plumbing, HVAC), asbestos or mold remediation, extensive foundation work, or other repairs that require the unit to be vacant.

Standard of review: Courts apply stricter scrutiny here than with demolition. You must prove the unit is actually unlivable and the work is necessary. Cosmetic improvements do not qualify. If you claim “major renovation” for a paint job or appliance upgrade, the notice will be void.

Key distinction: After demolition, the dwelling no longer exists. After major renovation, it is re-rented. This difference matters to courts assessing good faith. If you issue a major renovation notice and the unit is ready to rent 30 days later, a judge may question whether the repair actually required a full tenant removal.

Interaction with Portland’s Anti-Displacement Ordinances

If your property is in Portland, Oregon, you must also comply with Portland’s Residential Tenancies Ordinance (Portland City Code Chapter 30), which adds additional protections on top of state law.

Key requirement: Portland generally requires relocation assistance if you terminate a tenancy for demolition or major renovation. The assistance may include:

• Payment to the tenant toward moving costs (minimum $3,000–$4,500 depending on household size and income)
• Right to return at a controlled rent if the unit is renovated and re-rented
• Extended notice periods for tenants over 55 or with disabilities

Portland’s ordinance is separate from and in addition to ORS 90.427(7). You must comply with both. Failure to provide relocation assistance, even if you provided a proper 90-day notice, violates Portland law and exposes you to civil penalties and attorney fees.

If your property is in Portland: Consult a Portland-specific Oregon tenant law guide or an attorney before issuing any demolition or major renovation notice. This guide covers state law only.

Documentation Checklist: What to Keep for Dispute Resolution
