The Legal Limit: 6 Residents Maximum
Washington law (RCW 70.128) caps adult family homes at six residents. No exceptions. If someone tries to show you a "home" with 12 residents, it's either unlicensed or licensed under a different category. The six-person limit keeps homes intimate and manageable.
Some homes operate with fewer residents by choice — four or five — to maintain specific staff ratios or offer more spacious rooms.
Why This Law Exists
The state created the AFH model in the 1980s specifically to offer an alternative to institutional care. Small size makes it easier to integrate homes into neighborhoods, personalize care, and monitor quality. DSHS inspectors can audit every resident chart in a single visit, which isn't possible in huge facilities.
What 6 Residents Means for Daily Care
With only six people to care for, caregivers notice subtle changes faster — a missed meal, a restless night, a mood shift. Residents eat together, recognize each other's family members, and often form genuine friendships. Families build direct relationships with the provider rather than rotating shift supervisors.
It also means there are limited openings. A popular home might go months without a vacancy.
Staff-to-Resident Ratios
Most AFHs schedule one caregiver for up to six residents during the day, another in the evening, and either an awake overnight staff or the provider on call with monitoring systems. Homes serving high-acuity residents often add a second caregiver during peak hours. Ask each provider how they staff their six residents — the law sets the maximum headcount, not the required staffing plan.
How This Compares to Larger Facilities
Assisted living facilities in Washington average 80+ residents. Nursing homes range from 100–200. Staff ratios reflect that scale. If your parent needs quiet, predictable routines, the six-resident model is usually a better fit. If they crave a large social circle, a bigger community might make sense.
