Full Cost Breakdown

Cost Category	Low	Medium	High	Notes
Office Space	$3,540	$14,160	$47,200	A small home health agency can operate from a 500-1,000 sq ft office. Some states allow home-based offices initially.
State Licensing & Accreditation	$5,900	$23,600	$59,000	Medicare certification requires a cost report survey that takes 90-180 days and typically requires meaningful four-figure-to-low-five-figure consulting fees.
Agency Management Software	$3,540	$11,800	$35,400	EVV is federally mandated for Medicaid-funded home and community-based services under the 21st Century Cures Act (https://www.medicaid.gov/medicaid/home-community-based-services/guidance/electronic-visit-verification-evv/index.html). Kinnser, Axxess, and AlayaCare are popular platforms.
Insurance	$5,750	$17,250	$46,000	Home health agencies face significant liability from caregiver incidents in client homes. A two-million-per-occurrence general liability limit is the recommended floor.
Initial Staffing & Training	$3,540	$11,800	$29,500	Background checks are a low per-employee cost. Home health aide training programs are a meaningful three-to-low-four-figure per-employee investment.

Licenses & Permits in Washington

General Business License

Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states. Additionally, businesses must register for the B&O tax and any applicable retail sales tax. Many cities require a separate city business license endorsed onto the state license through a streamlined endorsement system.

Common Mistakes to Avoid

1
Underestimating Medicare/Medicaid billing complexity — hire an experienced home health biller from day one
2
Not understanding EVV compliance requirements — penalties for non-compliance are severe
3
Insufficient payroll capital — caregivers must be paid weekly even when insurers pay in 60-90 days
4
Not vetting caregiver staff thoroughly — one abuse or neglect incident can result in license revocation
5
Entering the market without building hospital and SNF discharge planner relationships first

Next Steps to Launch Your Home Health Care Agency

1
Obtain a Washington home health agency license from the Washington Department of Health before placing any caregivers
2
Register your Home Health Care Agency as an LLC with the Washington Secretary of State ($200 filing fee)
3
Complete Medicare and Medicaid certification survey if you plan to bill federal health programs
4
Conduct criminal background checks, TB testing, and reference verification for all caregivers per Washington requirements
5
Get professional liability, general liability, and workers compensation insurance for home health operations; premiums scale with caregiver headcount
6
Implement HIPAA-compliant scheduling and electronic visit verification (EVV) software — required in most states
7
Hire an RN clinical supervisor — most states require a licensed nurse to oversee patient care plans
8
Establish Washington-compliant caregiver training requirements: CPR/First Aid, patient transfer, infection control protocols

Frequently Asked Questions

Starting a home health care agency spans a wide range. A small private-duty (non-medical) agency can launch in the low-to-mid five figures. A Medicare-certified skilled nursing agency requires meaningfully more — well into the six figures — because of the survey process, clinical staff requirements, and capital needed to bridge the 60-day Medicare payment lag. Use the calculator on this page to model your specific scenario.

Requirements vary significantly by state. Most states require a home health agency license and Medicare/Medicaid certification (if billing government payers). The Medicare survey requires demonstrating clinical compliance and typically takes 90-180 days to complete after application.

Skilled home health involves Medicare/Medicaid-covered services provided by licensed clinicians (nurses, PTs, OTs) following a physician order. Non-medical home care (personal care aides, companions) doesn't require clinical licensure and is typically private-pay or Medicaid-funded. Skilled care pays more per visit but is more regulated.

Home health agencies net single-digit-to-low-double-digit percentage net margins. Medicare reimburses on a per-episode basis under the Patient-Driven Groupings Model (PDGM — see https://www.cms.gov/medicare/medicare-fee-for-service-payment/homehealthpps). A multi-patient agency generates meaningful annual revenue once at scale. Profitability requires efficient scheduling, low caregiver turnover, and strong billing practices.

Yes — Electronic Visit Verification is federally mandated for Medicaid personal care and home health services. Agencies must use an approved EVV system to electronically verify visit time, location, and services. Non-compliance results in claim denials and potential audit liability.
