Jefferson County septic installer bonds.
$100 flat.
Every septic installer working in Jefferson County, Washington, including installers based outside the county, needs an OSS installer certificate, and the certificate requires a $20,000 surety bond running to Jefferson County Public Health. The county’s On-Site Sewage Code fixes that amount. Ours is $100 flat for a term.

What it is and who needs it.
What the Jefferson County installer bond guarantees
Jefferson County regulates septic work through its On-Site Sewage Code, Chapter 8.15 of the Jefferson County Code, rewritten by the Board of Health with revisions effective April 1, 2025. Section 8.15.140(1) makes it unlawful for any person to engage in construction, alteration, repair, modification or decommissioning of an on-site sewage system (OSS) without first holding an OSS installer certificate issued by the health officer. The county certifies installers after an exam, demonstrated knowledge of septic systems, and proof of bonding and insurance — and installers based outside the county may work in it only if they hold the Jefferson County certificate.
The bond is one of the certificate’s conditions. Section 8.15.140(5)(a)(ii) requires a $20,000 bond running to the department, on a form the department approves, executed by a surety authorized to do business in Washington. It is conditioned that the certificate holder and their agents, in work governed by the chapter, will exercise all reasonable care and skill and comply with all of its terms. That is why one bond covers a certified installer’s crew: the code defines a site installer as someone working under the direction, insurance and bond of a certified installer.
Two features matter more than the amount. Cancellation of the bond automatically suspends the certificate, so a lapse stops your work in the county. And the bond must run for 36 months after the certificate ends, so claims tied to past installations can still reach it. It is a three-party arrangement: you (the principal), the surety, and the county health department (the obligee). It is not insurance for you — if the surety pays a claim, you repay the surety. The certificate also needs $500,000 of business liability insurance, a year of supervised experience, 16 education hours and a written exam.

Claims, renewal, filing, and what sets the price.
If a claim is made
A claim comes from the party the bond protects, the obligee named on the form, when the duty the bond guarantees is not met.
The surety investigates and pays a valid claim, up to the $20,000 bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.
Renewal and term
The term is set on the carrier’s application; the premium covers the period shown there.
Renewal falls on the statutory date, December 31, in the year your term ends.
Renew before the expiry date to keep the bond in force: the license, permit or contract it backs expects continuous coverage.

What sets the price
