Oregon Winter Habitability 2026–27: Heating, Pipes, and Documentation So You Do Not Hand the Tenant a Repair-and-Deduct or Termination Claim
Late October is when the first real cold snaps show up on the forecast and the Helpline starts marking heat and water calls again. For Oregon winter habitability 2026, the core heat-and-water rule has not changed since last January’s heating piece: under ORS 90.320 you must keep the dwelling unit habitable at all times during the tenancy (ORS 90.320(1)). That includes adequate heating facilities that conform to the law in effect when they were installed and stay in good working order, plus plumbing facilities that conform to the law in effect when they were installed and stay in good working order, and a water supply that can produce hot and cold running water.
What Oregon winter habitability 2026 requires under ORS 90.320 for heat and pipes
ORS 90.320 does not set a temperature number. It requires adequate heating facilities that conform to applicable law at the time of installation and are maintained in good working order. The same section requires plumbing facilities and a water supply capable of producing hot and cold running water, furnished to appropriate fixtures, and maintained in good working order.
Portland’s code is the overlay that adds the number. Under Portland City Code (PCC 27.05.021 and PCC 29.30.180), the heating facility must be capable of maintaining 68°F at a point three feet above the floor in all habitable rooms, and portable heaters do not count toward that requirement. That 68°F figure is Portland’s rule, not the state’s. ORS 90.320 itself sets no temperature number, so outside Portland check your own city’s code. What the statute does require everywhere is heating that conformed to the law when it was installed and is maintained in good working order.
A system that cannot heat the unit, a heat pump locked in cool mode, a furnace that will not light, or pipes that freeze because the heat was off all raise the same habitability question. The duty under ORS 90.320 is continuous: “at all times during the tenancy.” Under ORS 90.365, the tenant’s essential-service remedies apply when the landlord intentionally or negligently fails to supply the service, and you are not treated as failing if you substantially supply it, or if you are making a reasonable, good-faith effort and the failure is due to conditions beyond your control. That is exactly what your documentation has to show.
Essential services and the clocks that start when heat or water fails
When heating or water fails, the tenant can treat it as an essential-service issue under ORS 90.365. For a typical rental, the statutory definition (ORS 90.100) lists heat, plumbing, hot and cold running water, gas, electricity, light fixtures, exterior door locks, window latches, and any cooking appliance or refrigerator you supply, plus any other habitability item whose lack seriously threatens the tenant’s health, safety or property or makes the unit unfit to occupy. The statute gives the tenant remedies if the landlord intentionally or negligently fails to supply them.
A written notice from the tenant starts the clock. The essential-service path moves faster and has no fixed dollar cap. The minor-defect path under ORS 90.368 is capped at $300, and the tenant’s notice must give you at least seven days to make the repair. A total loss of heat or water is usually an essential-service issue. Leaky plumbing or a stopped-up toilet is the statute’s own example of a minor habitability defect.
The statutory clocks are these:
ORS 90.365(1): after written notice, the tenant must allow you a reasonable time and reasonable access to restore the service. After that, the tenant may buy reasonable amounts of the service and deduct the actual and reasonable cost from rent, recover damages for the reduced rental value, or, if the unit is unsafe or unfit to occupy, move to substitute housing and pay no rent for that period.
ORS 90.365(2): if the missing service poses an imminent and serious threat to the tenant’s health, safety or property, the tenant’s written notice can terminate the rental agreement in not less than 48 hours unless you remedy the breach within that period.
ORS 90.360(1)(a): for a material breach, the tenant’s written notice must specify the breach and set a termination date not less than 30 days after delivery, and the agreement terminates on that date if the breach is not remedied within seven days for an essential service, or 30 days in all other cases. For a week-to-week tenancy, the termination date is not less than seven days after delivery. Under ORS 90.360(1)(b), if you adequately remedy the breach before the date in the notice, the rental agreement does not terminate. Under ORS 90.360(1)(c), if substantially the same breach recurs within six months, the tenant can terminate on at least 14 days’ written notice (seven for week-to-week). ORS 90.360(2) separately lets the tenant recover damages and seek an injunction. A tenant who uses ORS 90.365 or 90.368 for a breach cannot also terminate under ORS 90.360(1) for that same breach (ORS 90.365(5), 90.368(6)).
ORS 90.368: repair-and-deduct of up to $300 for a minor defect (ORS 90.368(1)–(2)), with a repair date at least seven days after the notice is given to you (ORS 90.368(3)(b)). The tenant cannot do the repair work personally (ORS 90.368(4)(c)).
ORS 90.365(7): if a 90.365 notice is delivered by first-class mail, three days are added to the notice period.
Your own office clocks on top of that:
Same day or next morning written response when the tenant reports no heat or no water.
Reasonable access given so the contractor can enter.
Documented delay only when the delay is outside your control (parts on order, weather, or the tenant’s refusal of access). That record supports the good-faith-effort defense in ORS 90.365(3).
Do not let a verbal “we’ll get to it” be the only record.
A tenant who has given written notice and does not get the service restored can take the next statutory step: substitute service and deduct, reduced-rent damages, substitute housing, or a termination notice. A reply alone does not stop those clocks; the repair does. A file that shows a same-day written reply, offered access, and a scheduled repair is the file that shows a reasonable, good-faith effort.
The documentation that keeps the claim from forming
The record that answers a 90.365 or 90.368 notice is simple and ordinary. It is not a legal brief. It is a same-day written reply plus the work order.
Keep:
The tenant’s notice (text, email, or portal message) with the time stamp.
Your written reply the same day or the next morning, stating what you are doing and when.
The work order or contractor dispatch with the appointment time.
Photos of the thermostat, the equipment, or the pipe if they help show the condition.
Any invoice or confirmation that parts were ordered or the repair was completed.
A note if the tenant delayed access.
Store the file with the tenancy. If the tenant later claims you ignored the notice, the timestamps and the work order are the answer.
Portland overlay notes
Portland’s 68°F rule is the local addition, and it is a performance test: the heating facility must be capable of maintaining 68°F at three feet above the floor in every habitable room, and a portable heater cannot be used to meet it (PCC 29.30.180). Under ORS 90.320, the question is whether the heating facilities conformed to the law that applied when they were installed and are in good working order.
Portland also has its own relocation-assistance and notice rules for other issues. Those rules do not change the habitability duty under ORS 90.320. Heat and water failures are answered under the statewide statutes, with Portland’s code on top.
and now a couple shameless plugs.
The Portland Area Rental Owners Association (PAROA) Helpline still sees damages, repair, and heat calls every winter. Members get the forms, the latest statute language, and a place to check the notice clock before you reply. Join at www.paroa.org.
Northwest Real Estate and Property Management (NWRPM) handles the winter dispatch and the paper trail for owners who would rather not field the 11 p.m. “no heat” text themselves. For Portland Metro and Central Oregon properties, the operational side of keeping the system running and the file complete is what we do. www.nwrpm.com.
Pipe freeze and the system checks that prevent it
A frozen pipe is usually a heat problem first. Empty units, units set too low, or units with heat turned off at the breaker produce the same result. Before the first hard freeze:
Confirm the heating system starts and holds temperature.
In vacant units, leave the heat on at a level that keeps the pipes from freezing.
Know where the shutoffs are.
Have a plumber’s number already in the file.
If a tenant reports no heat, treat it as essential services and reply in writing the same day.
What not to hand the tenant
Do not treat a portable heater as the permanent fix and then stop answering. Do not ignore a tenant’s report because it arrived by email, text, or portal message instead of a mailed notice. Whether it counts as formal written notice depends on ORS 90.150 and 90.155 and your rental agreement, but either way you now know about the condition. Do not let the only record be a verbal “we’ll get to it.”
The goal is simple: the file shows the system was capable, you responded in writing the same day or the next morning, you gave reasonable access, and any delay was documented as outside your control or already scheduled. That is the difference between a cold night and a repair-and-deduct or termination claim.
