Oregon compliance obligations
Oregon landlords commonly track 7 state and local compliance obligations, each listed below with its schedule, its sources, and the date we last verified it. Among them: file the Oregon annual report if an LLC or corporation owns the property, if your rental is in Portland city limits, register it on Schedule R by April 15, and pay Oregon property tax (full or first trimester) by November 15.
File the Oregon annual report if an LLC or corporation owns the property
If an LLC or corporation holds the property, it must file an annual report with the Oregon Secretary of State by its registration anniversary each year ($100 for an Oregon entity, $275 for one formed in another state), and a report still missing 45 days after the Secretary of State's notice lets the state administratively dissolve the company or revoke an out-of-state company's authority to do business in Oregon.

If your rental is in Portland city limits, register it on Schedule R by April 15
If your rental is inside Portland city limits, list every unit on Schedule R with your Portland and Multnomah County business tax return each year (generally due April 15, and required even when no business tax is owed) and pay the per-unit registration fee by that date, or face late payment penalties, interest, and a civil penalty of up to the full fee for each unregistered unit.

Pay Oregon property tax (full or first trimester) by November 15
Paying the full year's tax by November 15 earns a 3% discount (2% for paying two-thirds), and a first one-third installment still unpaid after December 15 starts accruing interest at 1.333% per month.

Pay final property tax trimester installment by May 15
The final one-third of the annual property tax is due May 15, and unpaid balances after this date accrue interest and can eventually trigger foreclosure processes.

Return security deposit with itemized statement within 31 days of move-out
Oregon law (ORS 90.300) requires returning the deposit, less any deductions, with a written accounting stating the specific basis of each deduction within 31 days after the tenancy ends and the tenant delivers possession, by personal delivery or regular first class mail (certified mail alone does not count, and email only under a signed email addendum), because a missing or late accounting, or a bad faith withholding, lets the tenant recover twice the amount withheld.

Verify smoke and carbon monoxide alarms and give tenants testing instructions
Before each new tenancy, Oregon landlords must have working smoke alarms with working batteries, and a working carbon monoxide alarm where the unit has a fuel-burning heater, fireplace, appliance, or stove or an attached garage opening into the living space, or connects by a door, duct, or vent to a room in the building that has one, and must give the tenant written testing instructions at move-in, because these are habitability duties and a missing smoke alarm can bring a fire official's citation and a State Fire Marshal civil penalty of up to $250.

Seasonal maintenance for Oregon
Landlords in Oregon plan upkeep around a temperate climate: this guide lists 8 seasonal maintenance items for Oregon in calendar order, each with its timing and the date we last verified it. Among them: exterior paint and siding moisture check, smoke and CO detector seasonal test, and create defensible space and clear flammable debris before fire season.
Exterior paint and siding moisture check
Checking paint and siding after the wet season prevents rot and moisture intrusion in mild climates.
Around March · Verified before August 2026
Smoke and CO detector seasonal test
An annual full test of smoke and CO detectors (beyond battery swaps) confirms every alarm actually sounds.
Around March · Verified before August 2026
Create defensible space and clear flammable debris before fire season
Clearing leaves, needles, and dead vegetation from the roof, the gutters, and the first 30 feet around the home each spring, before fire season is declared and summer dries the fuel, slows an approaching wildfire and gives firefighters room to defend the home.

Remove roof moss and treat it during a spring dry spell
Where moss grows on the roof, as it commonly does in the wet climate west of the Cascades, it traps soil and debris that keep the roof wet longer and can shorten its life, and moss products work best on actively growing moss in a spring dry spell with no rain expected for a few days, so brush or scrape the moss off or hire a roofer (never pressure wash the roof) and then apply a moss control product if needed.

HVAC seasonal service
A shoulder-season HVAC service keeps heating and cooling efficient before temperature swings.

Clean gutters and inspect roof and downspouts before fall rains
West of the Cascades most of the year's rain falls from October to April, and October alone averages more than 3 inches in the Willamette Valley and nearly 7 inches at Astoria, so clearing the gutters and downspouts and checking the roof ahead of the October rains keeps water running off the roof and away from the siding and foundation, and a second clearing once the leaves are down helps wherever large trees overhang the roof.

Run an earthquake readiness check during ShakeOut month
Oregon is earthquake country, and the offshore Cascadia subduction zone can produce a magnitude 9 quake, so an October check, timed with the Great Oregon ShakeOut drill, that the water heater is strapped, heavy furniture is secured, the household knows where the gas and water shutoffs are and keeps a wrench for the gas valve, and two weeks of emergency supplies are on hand limits injuries and damage when the ground shakes.

Winterize outdoor faucets, hose bibs, and irrigation before first freeze
First freezes typically arrive in September in Central Oregon, the Klamath Basin, and the eastern high desert, in October in the Columbia Basin, and from late October into December west of the Cascades, so draining outdoor faucets and hose bibs, shutting off and draining irrigation, and insulating exposed pipes before then (by mid-September on the high desert) helps prevent burst pipes and water damage.
