How to Start an Adult Family Home in Washington: DSHS License, 48-Hour Business Class and Up to 6 or 8 Residents

If you want to learn how to start an adult family home business in Washington, you are running two processes at once. The first is the business side: choosing a structure, filing with the Secretary of State, and registering with the Department of Revenue. The second is the facility side: a license from the Department of Social and Health Services (DSHS) Residential Care Services that lets you care for residents in your home. You need both before you take in anyone. This guide walks through the steps in the order that avoids the most rework.

Informational content only. This article is not legal, tax, or licensing advice. Rules, fees, and processing times change. Confirm current figures with the agency named in each step, and talk with a qualified attorney or CPA before you sign a lease, form an entity, or hire staff.

What You Will Need

Gather these before you start, because several items feed into more than one application.

• Two or three business name options, each checked against the Secretary of State business search
• A registered agent with a physical Washington street address and an email address, if you form an LLC or corporation
• Government-issued photo ID and proof of a high school diploma or equivalent
• Records documenting 1,000 hours of direct caregiving in the prior 60 months, unless you hold a physician, PA, RN, APRN or LPN license
• A written business plan and a start-up budget that shows how you will fund operations
• Control of the property, plus the address and floor plan you will use for zoning review
• Access to the Corporations and Charities Filing System (CCFS) and the Department of Revenue Business Licensing Service (BLS) online application
• A fee budget. Known state figures appear in the steps below. DSHS license fees are set in the state budget, so confirm them with DSHS before you budget.

Step 1: Decide Your Capacity Before You Shop for a Building

Under chapter 70.128 RCW and chapter 388-76 WAC, an adult family home serves more than one and up to six adults. With department approval, it can serve up to eight (RCW 70.128.010). If you add a seventh or eighth resident, you must give residents 60 days written notice.

Capacity drives cost and building requirements, so settle it first. DSHS license fees are charged per bed, which means an eight-bed plan costs more to license than a six-bed plan. Assisted living is a separate license for operations of 7 or more residents under chapter 18.20 RCW and chapter 388-78A WAC, with its own per-bed fees. The seven and eight resident options sit close to that line, so ask DSHS to confirm in writing which license fits your plan.

Step 2: Confirm Your Qualifications

The provider or resident manager must meet all of these requirements:

• Be 21 or older
• Hold a high school diploma or equivalent
• Have 1,000 hours of direct caregiving in the prior 60 months, or hold a physician, PA, RN, APRN or LPN license
• Complete DSHS basic and specialty training

If you plan to hire a resident manager, that person must meet the same requirements. Collect your caregiving records now. Employment letters and timesheets are the easiest records to lose, and you will need them for the application.

Step 3: Choose Your Business Structure

Your structure determines which state filings apply.

• Sole proprietorship or general partnership: No Secretary of State filing is required. You still register with BLS, and if you operate under a name other than your full legal name, you must register that trade name.
• Limited liability company (LLC): File a Certificate of Formation with Initial Report through CCFS. The filing fee is $180.
• Corporation: File Articles of Incorporation with Initial Report through CCFS. The filing fee is $180.

An LLC or corporation can help separate personal assets from business obligations, but it does not protect you from liability for your own negligent acts. Ask an attorney how the entity fits your insurance and liability picture.

Name Rules for LLCs

Under RCW 23.95.305, an LLC name must include “Limited Liability Company,” “Limited Liability Co.,” “L.L.C.,” or “LLC.” It must be distinguishable from every other business name on record with the Secretary of State. It cannot include bank, banking, banker, trust, cooperative, any combination of industrial and loan, or any combination of two or more of building, savings, loan, home, association and society. That last rule matters for care businesses, because “home” is a common word in this industry. Pairing it with “association” or “loan” is not allowed, so check your name before you pay for anything. If you need time to finalize it, you can reserve a name for 180 days for $30.

Registered Agent

Every business must designate a registered agent in Washington. The agent may be commercial (registered with the Secretary of State) or noncommercial, must consent to serve, must supply an email address, and must have a physical Washington street address. PO Boxes and private mailbox addresses are not accepted. There is no fee to change the registered agent.

If you need the entity filed quickly, expedited service costs $100 per business entity and is generally processed within three business days. The Secretary of State does not publish a standard turnaround for regular online filings, so plan for variability.

Step 4: Register With the Business Licensing Service

Washington has no corporate income tax and no personal income tax, but it does have a statewide business license. The Department of Revenue's Business Licensing Service issues the 9-digit Unified Business Identifier (UBI) and handles trade names and state and city endorsements in one application. LLCs, corporations, and partnerships must file with the Secretary of State before you submit the Business License Application.

You need a BLS application if any of these apply: you operate under a name other than your full legal name, you plan to hire employees within 90 days, your gross income is $12,000 per year or more, or you owe a tax or fee to the Department of Revenue. An adult family home that bills for care will likely meet at least one of these conditions, so plan to file.

The processing fee to open a business is $50, plus separate endorsement fees. Online applications take about 10 business days, and 2 to 3 weeks longer when city or state endorsements need approval. Mailed applications can take up to six weeks. Apply at dor.wa.gov/open-business/apply-business-license.

If you will operate as a name such as “Riverbend Care” rather than your legal name, register that trade name on the same application. Each trade name costs $5, on top of the $50 processing fee. Trade names are registered through the Department of Revenue, not the Secretary of State or the county. Details are at dor.wa.gov/manage-business/grow-business/register-trade-names.

Step 5: Clear Zoning, Local Taxes and Health Requirements

Washington has 39 counties and 281 incorporated cities and towns, so local rules vary. Before you sign a lease or buy a house, contact the city or county planning department and ask:

• Is an adult family home a permitted use in this residential zone, or does it need a conditional use permit?
• Which local business license, endorsement, or home occupation rules apply?
• What fire and building requirements apply to a home serving residents who need help with daily living?

Also ask your local health district whether it issues any permit for your operation. Local business and occupation taxes are separate from the state B&O tax. About 54 cities add their own B&O tax, and the Department of Revenue does not administer those local taxes, so confirm the rate and filing requirements with your city directly. Get answers in writing where possible.

Step 6: Complete the 48-Hour Administration and Business Planning Class

Under RCW 70.128.120, applicants must complete a 48-hour administration and business planning class before licensing. Treat it as a planning tool, not just a certificate. Take the class early, and ask DSHS Residential Care Services which course providers it accepts and what scheduling rules apply.

Step 7: Complete DSHS Basic and Specialty Training

The provider or resident manager must complete DSHS basic training and specialty training. Specialty training is tied to the populations you plan to serve, so match your training choices to your admissions plan and confirm which specialties apply. Ask DSHS for the current schedule, course formats, and any deadlines tied to your application. Keep every certificate in one folder, because DSHS will expect copies.

Step 8: Document Financial Solvency

Applicants must show financial solvency before licensing. The state sets no threshold in this guide, so ask DSHS which documents it accepts. Build a start-up budget that covers at least:

• Staffing and training costs
• Food, utilities, supplies, and housekeeping
• Insurance, professional fees, and state filing fees
• DSHS license fees for your planned bed count
• Operating reserves for months when occupancy runs below plan

Have bank statements and funding documentation ready, and be able to explain where your start-up money comes from.

Step 9: Apply for the DSHS Adult Family Home License

Submit your application to DSHS Residential Care Services. Confirm with DSHS which documents must accompany the application and which must be completed before licensing. The license fee is a per-bed fee plus processing fees set in the state budget (RCW 70.128.060(11) and WAC 388-76-10025). You pay it with the application and again every year in your licensing month. DSHS publishes the current amounts, so check them before you finalize your budget.

The license is valid only for you as the provider and for that home, and it is not transferable (WAC 388-76-10010). If you buy a house that already operates as an adult family home, the license does not come with the property. Plan on your own application under your name.

Step 10: Set Up Your Tax and Employer Accounts

Washington's main business tax is the business and occupation (B&O) tax, a gross receipts tax with more than 50 activity classifications. It allows no deduction for labor, materials, or other costs, so your gross receipts are the base. Ask the Department of Revenue which classification fits your care services. If you hire staff, confirm workers' compensation requirements with the Department of Labor and Industries (L&I) and unemployment insurance registration with the Employment Security Department (ESD) before your first hire.

Step 11: Keep Your Filings Current

• LLC and corporation annual reports: $70, due by the last day of the month in which the entity was formed, every year. You may file up to 180 days early. A late filing carries a delinquency fee, for a total of $95.
• DSHS license fee: Paid every year in your licensing month. Put that date on your calendar from the day you are licensed.
• Adding residents: Give residents 60 days written notice before adding a seventh or eighth resident.
• Registered agent: Keep the agent's address and email current. Changing the agent carries no fee.
• BLS and trade name records: Keep your information with the Department of Revenue current when your name, address, or operations change.

Realistic Timeline

The business filings can move quickly. Expedited entity filings are generally processed within three business days, and online BLS applications take about 10 business days, plus 2 to 3 weeks when endorsements need approval. Regular Secretary of State filings have no published standard turnaround. This guide does not state a DSHS processing time, so ask the agency for its current window and the order it expects you to complete each step.

Expected Results

Operators who complete these steps in order may open a licensed home with fewer surprises. Results vary widely based on location, payer sources, occupancy, staffing, and how carefully you manage costs. Occupancy can build slowly, so plan reserves for a ramp-up period. This article does not promise any revenue, occupancy level, or opening date. Treat your first year as a period to build the operation, not as a guaranteed return.

Common Mistakes to Avoid

• Signing a lease before zoning is confirmed. A lease for a property you cannot use for residential care is costly to exit.
• Assuming the license comes with the house. The license is tied to the provider and the home and cannot be transferred.
• Choosing a restricted name. An LLC name that pairs “home” with “association” or “loan” will not be accepted.
• Using a business name you have not registered. A trade name registration is required when you operate under a name other than your legal name.
• Using a PO Box for the registered agent. The agent needs a physical Washington street address.
• Missing the annual report. A late filing brings the total to $95, compared with the $70 filing fee.
• Adding residents without notice. A seventh or eighth resident requires 60 days written notice to residents.
• Overlooking local B&O tax. The state tax does not cover the separate local B&O taxes that about 54 cities levy.
• Treating training as an afterthought. Basic training, specialty training, and the 48-hour class all come before licensing, and they take time to schedule.

Practical Tips

• Reserve your name first if you need time to finalize it, and check it against the business search before you file.
• Pay for expedited service when a fixed opening date depends on the entity filing.
• Start your caregiving records file now, while past employers are still reachable.
• Call DSHS Residential Care Services before you sign anything to confirm current fee amounts and required documents.
• Ask the Washington Small Business Development Center to review your business plan before you finalize it.
• Consider a CPA for tax setup and an attorney for entity and lease review. Weigh those professional fees against a rejected filing or a lease you cannot use.
