Our annual rental property maintenance checklist puts it plainly: fall is the most important season for a Pacific Northwest landlord. Everything done before the rains prevents water damage during the months that follow, and winter is mostly about monitoring, fast response and protecting against cold snaps.
This page gathers that work in calendar order. Each item links to the page where we cover it in full, whether you own a single-family rental, an apartment or commercial building, or a marina.
What Washington Law Asks of a Landlord
Washington has no dated statewide "heat season." The landlord's duties under RCW 59.18.060 apply at all times during the tenancy. The statute says the landlord will keep the premises fit for human habitation, and among the specific duties it lists are to:
- "Maintain the structural components including, but not limited to, the roofs, floors, walls, chimneys, fireplaces, foundations, and all other structural components, in reasonably good repair so as to be usable"
- "Maintain all electrical, plumbing, heating, and other facilities and appliances supplied by him or her in reasonably good working order"
- "Maintain the dwelling unit in reasonably weathertight condition"
- "Provide facilities adequate to supply heat and water and hot water as reasonably required by the tenant"
The statute itself names no start date and no indoor temperature. Those duties run year-round; fall is simply when a building's heating system, roof and envelope are put under the most load. City housing codes can add requirements of their own, so check the rules where your property sits. For the rest of the Act, see our Washington landlord-tenant law quick reference.
This is general information, not legal advice. Wilson Management, Inc. is a property management company, not a law firm. Verify the current text of any statute at the Washington State Legislature and consult a qualified Washington attorney before acting.
What the National Weather Service Advises
The National Weather Service frames winter preparation around the building, not just the people in it. Its winter storm guidance says that "your primary concerns at home or work during a winter storm are loss of heat, power and telephone service," and asks you to make sure a carbon monoxide detector is working and that "the outside vent is clear of leaves and debris." Its cold weather guidance adds: "Take precautions to ensure your water pipes do not freeze," and recommends making a check of the forecast part of your regular routine.
For properties in the Puget Sound area, current watches, warnings and advisories come from the NWS Seattle/Tacoma forecast office.
The Fall and Winter Plan, in Calendar Order
Early fall, before the rains
Gutters, downspouts, drains and sump
Clean gutters and downspouts before the rainy season starts, make sure downspouts carry water away from the foundation, clear exterior and French drains, and test the sump pump and its backup.
Fall checklist → Ask us about this →
Before each wet season
Single-family homes
Gutters twice a year on a treed lot, moss treatment, a roof inspection before the wet season and annual heating service, so a lifted shingle is found in October rather than reported as a ceiling stain in January.
Single-family maintenance →
Late summer to early autumn
Commercial and retail buildings
Roof drains and scuppers cleared, envelope and glazing seals inspected, exterior lighting checked ahead of the dark months, and storefront matting replaced before the wet season.
Commercial schedule → Storefront weather care →
Before the storm season
Marina windstorm preparation
Puget Sound windstorms are forecast with useful lead time. Before the season, docks, piles, cleats and mooring hardware are checked; ahead of a forecast event, tenants are told early and every dock is walked.
Marina storm response →
Through winter
Winter monitoring: leaks, ice dams, frozen pipes
Watch for ice dams, roof leaks and interior condensation, keep the heat running enough to prevent frozen pipes during cold spells, and check crawl spaces for moisture after storms.

How We Handle It for Owners
Routine and preventive work is the most cost-effective maintenance there is. For the properties we manage, we help schedule and oversee seasonal and recurring tasks such as HVAC servicing, gutter and drainage care, exterior and common-area upkeep, and inspection of major systems, so small issues are handled on a planned basis rather than discovered during an emergency.
When something does fail, residents submit requests through their AppFolio portal, which records when the problem was reported. Each request is reviewed and prioritized, the right vendor is dispatched, and routine work under the approval threshold you set proceeds without delay while larger expenses come to you first. Every job and its cost flows into your owner statements. More on that in Property Maintenance Services.
