Washington Significantly Restricts Noncompetition Agreements: What Dentists and Their Employers Need to Know

By Tyler Jones, Helsell Fetterman LLP  |  Shared by Dental Accounting Group  |  March 2026

Washington has enacted sweeping changes to the enforceability of noncompetition agreements that will directly impact dental practices, associate dentists, and dental service organizations (DSOs). House Bill 1155, effective June 30, 2027, will render most noncompetition covenants void and impose new compliance obligations on both employers and workers.

This is a significant development for dental practice owners who have historically relied on noncompete provisions to protect patient goodwill, referral relationships, and workforce stability. Here is what you need to know.

 

Key Takeaways

Topic

Key Provision

Effective Date

June 30, 2027. Applies to noncompetition agreements regardless of when they were signed.

Most Noncompetes Void

Most noncompetition agreements — especially those involving employees — will be unenforceable beginning June 30, 2027.

Expanded Definition

The law broadly defines “noncompetition covenant” to potentially include restrictions on accepting business from clients, patients, or customers — capturing provisions that have historically straddled the line between noncompetition and nonsolicitation.

Patient Restrictions

Overly broad limitations on treating former patients may be treated as noncompetition covenants and rendered void.

Notice Deadline

By October 1, 2027, employers must notify current and former employees and contractors that covered noncompetition agreements are void and unenforceable.

Penalties

$5,000 statutory damages per violation, plus attorneys’ fees. The Washington Attorney General may also bring enforcement actions.

What Is Still Permitted

Nonsolicitation of employees and patients (generally limited to 18 months). Noncompetes tied to the sale of a dental practice with at least 1% ownership interest. Confidentiality and HIPAA-compliant protections for patient information.

 

What This Means for Dental Practice Owners and DSOs

Dental practices and DSOs have historically relied on noncompetition agreements to protect patient goodwill, referral relationships, and workforce stability. These tools will now be significantly limited.

Practice owners and DSOs should expect reduced ability to restrict where associate dentists practice after departure, and will need to place greater reliance on carefully drafted nonsolicitation and confidentiality provisions. Retention strategies that go beyond restrictive covenants will become increasingly important.

The broader definition of “noncompetition covenant” is particularly worth noting. Provisions that restrict accepting business from patients — which some agreements use in lieu of traditional noncompetes — may now be captured under the new law and treated as void.

 

What This Means for Associate Dentists

Associate dentists — particularly those employed by DSOs — should be aware that many existing noncompetition provisions may become unenforceable under the new law beginning June 30, 2027. Associates should review whether current agreements contain provisions that may be void under the new law, how patient-related restrictions are structured and whether they are overly broad, and evaluate opportunities to revisit restrictive covenants in connection with employment changes or renegotiations.

 

What Is Still Permitted

Not all restrictive covenants are eliminated. The following protections remain available:

       Nonsolicitation agreements are still permitted, but are generally limited to 18 months.

       Noncompetition covenants tied to the sale of a dental practice remain enforceable, provided the restricted party holds at least a 1% ownership interest in the practice being sold.

       Confidentiality provisions and HIPAA-compliant protections for patient information remain valid.

 

Recommended Next Steps

 

For Practice Owners & DSOs

       Review and revise all associate and employment agreements now — before the June 30, 2027 effective date.

       Update template agreements used for future hires to comply with the new law.

       Plan for the required statutory notice obligation due by October 1, 2027.

       Invest in nonsolicitation and confidentiality provisions as your primary protective tools going forward.

       Consider retention strategies that reduce reliance on restrictive covenants.

For Associate Dentists

       Review your current employment agreement, particularly if you are affiliated with a DSO or multi-location group.

       Identify any noncompetition provisions and assess whether they may be void under HB 1155.

       Evaluate whether patient-related restrictions are overly broad and may be captured under the new definition.

       Seek legal advice before signing new or amended employment agreements.

       Consult an attorney when negotiating changes to existing agreements.

 

 

Required Action for Employers: By October 1, 2027, employers must make reasonable efforts to notify both current and former employees and independent contractors that any covered noncompetition covenant in their agreements is void and unenforceable under Washington law.

 

Failure to provide this notice may contribute to violations that trigger $5,000 in statutory damages per violation, plus attorneys’ fees.
