Western Washington built its housing for rain, not heat — and late summer now brings both hot stretches and smoke. Here is a practical plan for keeping an older parent safe in King, Snohomish, and Pierce counties.

A 90-degree day in Phoenix and a 90-degree day in Ballard are not the same event. Much of the Puget Sound housing stock was built without central air conditioning, because for most of the region's history it did not need it. That is changing — window and heat-pump installs have climbed steeply since the June 2021 heat dome — but plenty of older homes, apartments, and even some older care buildings still cool only what one window unit can reach.
The 2021 event is the reason local agencies now take heat seriously. The Washington State Department of Health attributed roughly 100 deaths statewide to that late-June heat, and the people who died skewed heavily older and were often alone at home without cooling. Age raises risk on its own: the body's ability to shed heat declines, thirst signals weaken, and common prescriptions — diuretics, beta blockers, anticholinergics, some antipsychotics and antidepressants — blunt sweating or fluid balance. Ask the prescribing clinician or pharmacist directly whether a parent's medication list raises heat risk.
Someone living with Alzheimer's or another dementia may not report feeling hot, may not think to drink, and may keep a cardigan on through a 92-degree afternoon because layering is habit. Heat also amplifies confusion and late-day agitation, so a caregiver can end up managing a behavioral crisis that is really a physiological one.
Practical adaptations that work: put water in view and offer it on a schedule rather than waiting to be asked, use high-water-content foods like melon and popsicles, lay out lighter clothing so the choice is already made, and move the day's activity to early morning. If a parent wanders, heat and smoke days raise the stakes considerably — this is often the season when families first look seriously at a secured setting.
Wildfire smoke season in western Washington typically runs from mid-July through September, and it does not require a local fire — smoke drifts in from eastern Washington, Oregon, and British Columbia. Fine particulate is hardest on older adults with COPD, asthma, heart failure, or coronary disease.
Check conditions before planning the day at AirNow.gov or through the Puget Sound Clean Air Agency, which monitors King, Kitsap, Pierce, and Snohomish counties. When air quality degrades, keep windows shut, run a HEPA purifier or a MERV-13 filter in a forced-air system, and pick one room to keep clean rather than trying to filter the whole house. Have prescription rescue inhalers refilled before smoke arrives, not during. Recirculate rather than draw in outside air when driving.
Cooling centers open during heat events through cities, libraries, and county human services — King County and the City of Seattle publish locations as events are declared, and the same is true in Snohomish and Pierce counties. The Area Agencies on Aging are the better first call for anything ongoing: Aging and Disability Services for King County, Homage for Snohomish County, and Aging & Disability Resources of Pierce County. Community Living Connections can screen a household for in-home help, meals, and utility assistance in a single conversation.
Low-income households can also ask about energy assistance for cooling equipment through their local community action agency; programs and funding cycles change year to year, so verify current terms rather than relying on last summer's answer.
If a parent already lives in licensed care, or you are touring this summer, ask concrete questions rather than general ones. Is there air conditioning in resident rooms, or only in common areas? What is the written plan when the building loses power during a heat event? Does the home have HEPA filtration for smoke days, and what happens to outdoor activities and transportation when air quality is unhealthy?
Washington's assisted living facilities are licensed under RCW 18.20 and adult family homes under RCW 70.128, both surveyed by DSHS Residential Care Services, and both are expected to maintain emergency and disaster plans. You are entitled to ask what that plan says. You can also review any home's license status and inspection history free through the DSHS provider lookup at fortress.wa.gov/dshs/adsaapps/lookup before you commit to anything.
A small adult family home — six residents or fewer, at roughly $4,500–$7,000 a month in this region — is often easier to cool and staff during a heat event than a large campus, but that depends entirely on the individual house. It is a question to ask, not an assumption to make.
