TL;DR
Washington regulates assisted living facilities under RCW 18.20 and WAC 388-78A through the Department of Social and Health Services (DSHS) Aging and Long-Term Support Administration. Licensing covers staffing ratios, resident agreements, medication assistance, and life safety. Medicare does not pay for assisted living room and board; Washington's Medicaid program covers some services through the Community First Choice and COPES waivers for eligible low-income residents.
What is assisted living?
Assisted living is a licensed residential setting where adults who need help with daily activities, bathing, dressing, medication management, or mobility, live in private or semi-private rooms and receive personal care services along with meals, housekeeping, and some health monitoring. It sits between independent senior housing and a nursing home on the care spectrum. In Washington, the state's legal term is "assisted living facility," defined in RCW 18.20.020 as a facility that provides housing and basic services (food, laundry, and some domestic services) plus arranges for or provides personal care and, in some cases, nursing and other health related services to seven or more residents not related to the operator [1]. Facilities with six or fewer residents are typically licensed as adult family homes under a separate chapter, RCW 70.128, which has its own rules and a different application track [2]. Assisted living is not a hospital and not a skilled nursing facility. Staff can help someone take their own medications, transfer with a gait belt, or manage a colostomy bag under nurse delegation, but they don't provide the round-the-clock skilled nursing that a Medicare-certified nursing facility does.
What is an assisted living facility, exactly, under Washington law?
An assisted living facility (ALF) in Washington is a state-licensed building or complex of buildings, holding a license issued by DSHS, where seven or more unrelated residents live and receive housing, meals, and assistance with activities of daily living, sometimes alongside limited nursing services delivered under RN delegation. The license category is set by RCW 18.20 and the operating rules are in WAC 388-78A [1][3]. A facility's license also dictates what level of care it can legally provide. Some ALFs hold a basic license only; others add an endorsement for specialized dementia care under WAC 388-78A-2900 through 2960, which requires additional staff training hours and physical environment features like secured egress and specific lighting and signage standards [4]. Washington also distinguishes ALFs from "boarding homes" (the older statutory term still used in some code sections) and from adult family homes. If you're comparing licensing categories side by side, it helps to look at the state's own assisted living facility licensing overview before you pick which chapter applies to your building size and business model.
What is a group home, and how does it differ from an assisted living facility?
"Group home" isn't a single defined license type nationally. It's used loosely to describe small residential facilities, often for people with intellectual or developmental disabilities (IDD), mental illness, or substance use recovery needs, usually licensed under a state's developmental disabilities administration or behavioral health rules rather than aging services rules. In Washington, homes serving adults with intellectual and developmental disabilities are typically licensed as Supported Living or Community Residential Services providers through DSHS's Developmental Disabilities Administration (DDA), under WAC 388-101 and related chapters, not under the assisted living statute [5]. Adult family homes (RCW 70.128) can also serve people with disabilities, mental health conditions, or aging needs in a small home setting of up to six residents, licensed under a different DSHS division than large ALFs. If your business plan involves a small home with six or fewer residents, you're probably looking at an adult family home license, not an assisted living facility license. If you're planning for seven or more residents in a purpose-built or converted building with congregate dining and larger staff, the ALF license under RCW 18.20 is the right track. Get this wrong early and you'll redo your application, your fire marshal walkthrough, and your staffing plan. For a broader look at how these categories compare across states, see assisted living facilities.
What does assisted living provide, day to day?
A licensed Washington ALF must provide at minimum: private or shared living units, three meals a day plus snacks, housekeeping and laundry, 24-hour staff awareness and response capability, help with activities of daily living (bathing, dressing, toileting, transferring, eating), medication assistance or administration under nurse delegation, and social and recreational activities [3]. WAC 388-78A-2400 through 2470 set staffing requirements: facilities must have sufficient staff, awake if needed based on resident acuity, to meet resident needs identified in each individual's negotiated care plan, and must maintain a written staffing plan that DSHS reviews at licensing and during inspections [3]. There's no single statewide numeric staff-to-resident ratio written into the WAC the way some states do it; instead, Washington uses an assessment-driven, negotiated service agreement model where the required staffing level is derived from each resident's documented needs, not a flat ratio. Every resident gets a negotiated care plan and a resident agreement (a contract) spelling out services, fees, and move-out conditions, required under RCW 18.20.190 and WAC 388-78A-2090 [1][3]. This paperwork is where most citations happen during inspections, because it's easy to let care plans go stale after a resident's condition changes.
What is assisted living vs nursing home, and how do the two compare in Washington?
| Typical resident need | Help with ADLs, medication assistance | 24/7 skilled nursing, rehab, complex medical care | |
|---|---|---|---|
| Licensing agency | DSHS Aging and Long-Term Support Administration | DSHS, also Medicare/Medicaid certified | |
| Nursing staff | RN delegation model, not required on-site 24/7 | Licensed nurses on-site around the clock | |
| Medicare coverage | Generally none for room and board | Covers up to 100 days per benefit period under certain conditions [7] | |
| Medicaid coverage | Services only, via waiver (COPES, CFC) | Room, board, and care covered for eligible residents | |
| Typical setting | Apartment-style or private room, congregate dining | Hospital-like wings, shared and private rooms | The practical difference for an operator: nursing homes require far more clinical staffing, a Medicare/Medicaid provider agreement process through CMS, and a much heavier compliance burden. ALFs are lower acuity by design and the license doesn't authorize the facility to hold itself out as providing skilled nursing care. |
Nursing homes (skilled nursing facilities) are licensed under RCW 18.51 and certified separately by the state and CMS to bill Medicare and Medicaid for skilled nursing and rehabilitative care. Assisted living facilities are licensed under RCW 18.20 and generally cannot bill Medicare at all, and can only bill Medicaid for services (not room and board) through specific waiver programs [1][6]. | Feature | Assisted living facility (RCW 18.20) | Nursing home (RCW 18.51) |
How do I start a group home or assisted living facility in Washington?
Start by deciding which license category fits your resident population and building size, because that decision drives everything else, your zoning research, your staffing plan, and your capital costs. Washington's process for an ALF generally runs through these steps: 1. Contact DSHS Aging and Long-Term Support Administration (ALTSA) Residential Care Services division to request a pre-application consultation and confirm current license fees, which the agency updates periodically. Confirm exact current fees with your state licensing agency rather than relying on any figure printed elsewhere, since these change. 2. Secure your site and confirm local zoning allows a residential care facility at that address (some jurisdictions treat ALFs as a permitted use, others require conditional use permits; this is a local, not state, decision). 3. Complete building and fire/life safety plan review. Washington ALFs must meet applicable building code requirements administered through local building departments plus fire safety provisions cross-referenced in WAC 388-78A [3]. 4. Submit the license application to DSHS with required documentation: business structure, floor plans, staffing plan, policies and procedures manual (admission/discharge criteria, medication management, abuse reporting, emergency preparedness), and background check clearances for owners and staff through Washington's background check system. 5. Pass a pre-licensing survey/inspection conducted by DSHS Residential Care Services surveyors, who check the physical plant, staff files, sample resident records, and policy compliance against WAC 388-78A. 6. Once licensed, operate under ongoing DSHS oversight including unannounced inspections and complaint investigations, and renew per the state's license renewal schedule. A lot of first-time operators underestimate the paperwork stage: the policies and procedures manual, resident agreement templates, staffing plan, and emergency preparedness plan. Building these from scratch, without a starting template, is where a lot of timelines slip by months. That's the exact gap the licensing kit builder is meant to close: a $299 one-time state-specific packet of licensing document templates so you're not drafting a medication management policy from a blank page the week before your survey. If you're still deciding what kind of facility to open, compare notes with the general assisted living primer and the state-by-state overview at assisted living facility before locking in your business plan.
What's the difference between assisted living and a nursing home in terms of licensing burden?
The regulatory weight is very different. Nursing homes require Medicare/Medicaid certification through CMS on top of state licensing, meaning a facility must pass both a state survey and a federal Certification survey using the CMS Long-Term Care Survey Process, and must comply with the federal Requirements of Participation at 42 CFR Part 483 [8]. Assisted living facilities in Washington answer only to state licensing under RCW 18.20 and WAC 388-78A; there is no federal ALF license or federal survey. That doesn't mean ALFs face light oversight. DSHS conducts licensing surveys, complaint investigations, and can issue statements of deficiency, require plans of correction, or in serious cases suspend or revoke a license under RCW 18.20.190 [1]. But the administrative layers (state only, versus state plus federal) explain why nursing home startup costs and staffing overhead run so much higher than ALF startup costs. Another practical difference: nursing homes must have a licensed nursing home administrator; ALFs must have a facility administrator meeting DSHS qualification requirements under WAC 388-78A-2270, which include specific training and, depending on facility size and dementia care endorsement, additional coursework, but not the same state administrator license required for nursing homes [3].
Does Medicare cover assisted living facilities?
No. Medicare does not pay for assisted living room and board, personal care, or custodial care in an ALF. CMS states plainly that "Medicare doesn't cover custodial care if it's the only kind of care you need" and that assisted living costs are generally the resident's or family's responsibility [9]. Medicare Part A can pay for a stay in a skilled nursing facility for up to 100 days per benefit period, but only after a qualifying hospital stay and only for skilled, not custodial, care [7]. Medicaid is the payer that can help with assisted living costs in Washington, but only for services, not room and board, and only for people who meet financial and functional eligibility. Washington runs this through its Community First Choice option and the COPES (Community Options Program Entry System) waiver, both administered by DSHS/HCA under the state's approved Medicaid state plan and waiver authority [10]. Room and board in an ALF is typically paid out of pocket or through the resident's own income (including, in some cases, Supplemental Security Income and a state supplement), while the personal care component may be Medicaid-funded for eligible residents. Operators planning to accept Medicaid-funded residents need a separate Medicaid contract with Washington's Health Care Authority or Aging and Long-Term Support Administration in addition to the DSHS facility license; the license alone doesn't authorize Medicaid billing.
What staffing and training does Washington require in assisted living facilities?
WAC 388-78A-2270 requires the facility administrator to complete specific initial training (Washington uses a defined initial certification and continuing education structure for ALF administrators) and pass required competency testing before independently operating the facility [3]. Direct care staff must complete orientation before working unsupervised, ongoing annual training hours specified in the WAC, and, for anyone assisting with medications, the state's medication assistance training and competency evaluation, since medication administration by unlicensed staff is only allowed under nurse delegation per RCW 18.79.260 and WAC 246-840 nurse delegation rules [3][11]. Facilities offering the specialized dementia care endorsement must provide additional dementia-specific training hours for staff before they work with residents in that unit, per WAC 388-78A-2931 [4]. DSHS surveyors check training files during inspections, and missing or expired training documentation is one of the more common deficiencies cited in ALF surveys nationally, according to patterns documented in CMS and state long-term care ombudsman reports. Background checks are mandatory for all staff with unsupervised access to residents, run through the Washington State Patrol and the DSHS background check central unit, before hire or before unsupervised contact, whichever the rule requires.
What are the zoning and physical plant requirements for a Washington assisted living facility?
Zoning for ALFs is set locally, city or county, not by DSHS, so the first call an aspiring operator should make is to the local planning or zoning department, more than the state licensing office. Many jurisdictions in Washington treat a licensed ALF as a permitted residential use in certain zones, but others require conditional use permits, especially for larger facilities or those in single-family zoned areas; this varies by county and city and must be confirmed locally, not assumed. Physical plant rules under WAC 388-78A cover minimum square footage per resident, private bathroom ratios, common space, emergency egress, and fire suppression system requirements that generally track the International Building Code as adopted by Washington, plus fire code provisions enforced by the local fire marshal [3]. New construction and conversions of existing buildings (like former hotels or large houses) both need plan review before a license will be issued. Because zoning approval, building permits, and DSHS licensing run on separate timelines and separate agencies, sequencing matters. Get preliminary zoning confirmation before signing a lease or purchase agreement; a building that looks perfect on paper can sit vacant for a year if the parcel isn't zoned for congregate residential care and a variance gets denied.
How does Washington inspect and enforce assisted living regulations?
DSHS Residential Care Services conducts licensing surveys before initial licensure, and follow-up surveys on a schedule plus in response to complaints. Surveyors review resident records, staff files, medication management logs, incident reports, and conduct physical walkthroughs checking life safety and sanitation. When a facility is found out of compliance, DSHS can require a plan of correction, issue civil penalties, restrict admissions, or in serious health and safety cases, suspend or revoke the license under RCW 18.20.190 [1]. Washington also publishes facility complaint and inspection history that consumers and prospective operators can review, since due diligence before buying or leasing an existing facility should always include pulling its inspection history from DSHS. Residents and families can file complaints directly with DSHS Complaint Resolution Unit or with the state Long-Term Care Ombudsman program, and ombudsman visits are a normal part of the oversight ecosystem alongside formal state surveys.
How much does it cost and how long does it take to get licensed?
Costs and timelines vary by facility size, whether it's new construction or an existing building conversion, and current DSHS fee schedules, which change periodically. Rather than quoting a specific dollar figure that may be outdated by the time you read this, confirm the current initial license fee, annual renewal fee, and any late or reinspection fees directly with DSHS Residential Care Services before budgeting. What's predictable is the sequence: zoning confirmation, building/fire plan review, staffing plan and policy manual development, license application submission, pre-licensing survey, and license issuance. Operators who have their policies and procedures manual, staffing plan, and resident agreement templates ready before submitting the application tend to move through DSHS review faster than those drafting these documents during the review period, simply because incomplete applications get returned for corrections rather than approved conditionally. If you're building this documentation set from zero, a state-specific licensing kit (templates for policies, staffing plans, resident agreements, and emergency preparedness plans mapped to WAC 388-78A) can shave real time off that drafting phase; that's the specific gap the $299 one-time licensing kit builder is built to fill, though it doesn't replace legal review of your final documents or guarantee any approval timeline.
Frequently asked questions
What is assisted living?
Assisted living is a licensed residential care setting for adults who need help with daily activities like bathing, dressing, and medication management, but not full-time skilled nursing. Residents typically have private or shared rooms, receive meals and housekeeping, and get personal care support. In Washington, this is regulated under RCW 18.20 as an assisted living facility license.
What is a group home?
"Group home" generally refers to a small residential facility, often for people with intellectual/developmental disabilities, mental illness, or in recovery, licensed under disability or behavioral health rules rather than aging services rules. In Washington, comparable small settings are licensed as adult family homes (RCW 70.128) or through DSHS's Developmental Disabilities Administration, not under the assisted living statute.
What is an assisted living facility?
An assisted living facility is a state-licensed building housing seven or more unrelated residents who receive housing, meals, and help with activities of daily living, sometimes with limited nursing services under RN delegation. Washington defines this under RCW 18.20.020 and regulates operations through WAC 388-78A, overseen by DSHS Aging and Long-Term Support Administration.
What is assisted living facility care, specifically?
Assisted living facility care includes help with bathing, dressing, toileting, transferring, and eating; medication assistance or administration under nurse delegation; meals, housekeeping, and laundry; social and recreational programming; and 24-hour staff awareness for emergencies. It does not include the round-the-clock skilled nursing care a hospital or nursing home provides.
What is assisted living vs nursing home?
Assisted living serves people who need help with daily activities but not constant medical care; nursing homes serve people needing 24/7 skilled nursing and rehabilitation. Washington licenses them under separate statutes (RCW 18.20 for assisted living, RCW 18.51 for nursing homes), and only nursing homes are Medicare/Medicaid certified for room, board, and skilled care.
What does assisted living provide day to day?
Day to day, assisted living provides three meals plus snacks, housekeeping and laundry, help with bathing and dressing, medication assistance, a negotiated individual care plan, activities and social programming, and staff on-site around the clock to respond to needs, per Washington's WAC 388-78A operating rules.
How do I start a group home in Washington?
Decide first whether your resident count and population fit an adult family home license (six or fewer residents, RCW 70.128) or a larger assisted living facility license (seven or more, RCW 18.20). Then confirm local zoning, complete building/fire plan review, build your staffing plan and policy manual, submit your DSHS application, and pass the pre-licensing survey.
How do I start an assisted living facility, step by step?
Contact DSHS Residential Care Services for a pre-application consultation, confirm zoning locally, complete plan review for building and fire code, submit your license application with a staffing plan and policies and procedures manual, pass the DSHS pre-licensing survey, and then operate under ongoing state inspection and renewal requirements.
What is the difference between assisted living and nursing home licensing burden?
Nursing homes require both state licensing and federal Medicare/Medicaid certification under 42 CFR Part 483, with a state administrator license and 24/7 licensed nursing staff. Assisted living facilities in Washington need only state licensing under RCW 18.20, with a facility administrator meeting DSHS training requirements, not a full nursing home administrator license.
Does Medicare cover assisted living facilities?
No. Medicare does not cover assisted living room and board or custodial personal care. CMS states Medicare doesn't cover custodial care when that is the only care needed. Medicare Part A can cover up to 100 days of skilled nursing facility care per benefit period, but only after a qualifying hospital stay, and that's a different facility type entirely.
Does Medicaid cover assisted living in Washington?
Medicaid can cover the personal care services (not room and board) in an assisted living facility for financially and functionally eligible residents, through Washington's Community First Choice option and the COPES waiver, administered by DSHS and the Health Care Authority. Facilities need a separate Medicaid contract beyond their DSHS operating license to bill for these services.
What's the difference between an adult family home and an assisted living facility in Washington?
An adult family home serves up to six residents in a house-like setting and is licensed under RCW 70.128. An assisted living facility serves seven or more residents, usually in a larger, purpose-built building with congregate dining, and is licensed under RCW 18.20 with its own WAC 388-78A rules. Staffing, training, and inspection details differ between the two chapters.
What training does Washington require for assisted living staff?
WAC 388-78A requires facility administrators to complete state-defined initial certification training and pass competency testing, direct care staff to complete orientation and annual continuing education hours, and anyone assisting with medications to complete medication assistance training under nurse delegation rules in RCW 18.79.260 and WAC 246-840.
How does DSHS inspect assisted living facilities in Washington?
DSHS Residential Care Services conducts a pre-licensing survey before initial licensure and follow-up surveys on a regular schedule plus in response to complaints. Surveyors review resident records, staffing files, medication logs, and conduct physical walkthroughs. Noncompliance can trigger a plan of correction, civil penalties, or license suspension/revocation under RCW 18.20.190.
