Selling a home with a septic system can feel intimidating. You want a smooth closing, clear expectations, and no last‑minute surprises. If your property is in Bow (Skagit County), understanding the county’s time‑of‑sale septic rules helps you get ahead of the process and protect your deal. In this guide, you’ll learn what “time of sale” means, which inspections count, how buyers will verify your records, and the steps to stay compliant. Let’s dive in.
What time of sale means in Bow
Time of sale refers to the septic inspections and documentation Skagit County may require before a property transfers. The goal is simple: protect public health and water quality, and make sure buyers know the system’s condition and any ongoing maintenance obligations. In practice, that means getting the right inspection done, handling any required repairs, and delivering clean documentation to the buyer and, when required, the county.
Who sets the rules
Skagit County Environmental Health is the local authority for on‑site sewage systems in Bow. Washington State Department of Health provides statewide technical standards and professional certification guidance, but the county decides if a time‑of‑sale inspection is required, which report forms are accepted, and how recent the inspection must be. Because rules can change, confirm your property’s exact requirements with Skagit County before listing.
Seller checklist
Use this start‑to‑finish workflow to stay on track:
- Contact Skagit County Environmental Health early to request your septic records and confirm the correct inspection type and report form for transfers.
- Hire a certified septic inspector or maintenance provider recognized by the county or Washington DOH.
- Complete the required inspection. For some systems, this is an Operation and Maintenance (O&M) inspection. Others may need a compliance or functional inspection. Advanced treatment systems may also require lab tests.
- Submit the inspection report as the county requires, and provide copies to the buyer and escrow.
- If repairs are needed, obtain permits, complete repairs under permit, and secure final approvals. Share documentation with the buyer and the county.
- If the county allows conditional transfers, prepare any required disclosure and escrow holdback agreements.
- If your system has an O&M contract, confirm how it transfers to the buyer and provide those details in writing.
Inspection types
Not all inspections are the same. Here is what you may encounter:
- O&M inspection. A routine check of key components like pumps, alarms, filters, distribution, and visible drainfield condition. Often used for systems with advanced treatment, pressure dosing, or pump stations.
- Compliance or functional inspection. A broader review to confirm there is no system failure, looking for signs like surfacing effluent, odors, backups, or saturated soils, and checking tank levels and distribution.
- Full evaluation or repair inspection. Used after repairs or when compliance is uncertain. This can include more invasive checks.
- Lab testing. Certain advanced systems may require lab results as part of compliance.
Ask your county contact which inspection type satisfies time‑of‑sale for your system.
Current inspection window
Counties define what counts as “current.” Some accept an O&M or compliance inspection done within 12 months of closing. Others accept up to 24–36 months if a previous passing inspection is on file. If your system requires ongoing O&M, the county may expect documented service on a set schedule, which can affect acceptability. When in doubt, confirm the acceptable window and whether the provider must submit the report directly to the county.
If your system fails
If an inspection finds a failure or required repair:
- Apply for the appropriate repair permit.
- Complete repairs under permit and schedule final inspections.
- Provide final approvals and invoices to the buyer and the county.
If timing is tight, ask whether Skagit County allows a conditional transfer with disclosures or an escrow holdback. Not all situations qualify, and the county decides what is allowed.
Buyer verification
Expect buyers and their agents to verify your septic documentation directly with Skagit County. They will often request the latest inspection report, any system permits, repair invoices and final approvals, O&M contracts, and any county‑required disclosure forms. Buyers commonly ask the county about permit status, inspection history, recorded repairs, and outstanding enforcement. Being proactive with complete, organized records builds trust and keeps your closing on schedule.
Red flags that prompt more questions include recent failed inspections, notes about surface discharge or drainfield ponding, missing O&M records for systems that require them, and inspector credentials that cannot be verified.
Find certified providers
Use certified professionals who are recognized by Skagit County or Washington DOH. When vetting providers:
- Ask for the inspector’s name, company, and credential or certification number.
- Confirm the credential with the issuing agency or county.
- Make sure the provider is authorized for the type of inspection you need. Not all pumpers perform compliance evaluations, and some work requires licensed designers or specific certifications.
Read your inspection report
A typical O&M or compliance report includes:
- Header. Property address, parcel number, owner name, inspection date, inspector name, and certification number.
- System type. Gravity, pressure, advanced treatment, aerobic unit, or other configuration.
- Components checked. Tanks, baffles, outlet filter, distribution box, pumps, floats, alarms, effluent filters, risers and access ports, and visible drainfield condition.
- Findings. Scum and sludge measurements, pump run times, alarm function, evidence of surface discharge or soggy soils, odors, or backups.
- Conclusion. Pass or fail, operational concerns, required repairs, and recommended service intervals.
- Follow‑up. Deadlines for repairs or re‑inspection and any O&M schedule requirements.
Key items to focus on:
- Scum and sludge depths. High levels suggest a needed pump‑out and can indicate neglect if very high.
- Drainfield condition. Surfacing effluent or saturated soils can indicate failure or a risk of failure.
- Pump and alarm performance. Alarms must be functional and tested.
- Outlet filter condition. Clogged filters can trigger backups and reduced performance.
- Pass versus needs repair. A pass means the system is functioning without immediate health hazards. Anything marked “needs repair” or “operational concerns” points to specific actions you must take.
Negotiation tips and timing
The earlier you confirm your septic status, the more leverage and predictability you have. Consider this approach:
- Before listing. Pull county records, schedule the required inspection, and handle repairs if needed. Share documentation with your listing agent so buyer questions are answered quickly.
- During marketing. Keep copies of reports and permits ready for buyers and escrow. If additional service is recommended but not required, note it so buyers can budget.
- During escrow. If the inspection triggers repairs, start permitting quickly. Discuss timing, credits, or holdbacks with your agent and escrow, based on county allowance.
Clear communication and complete paperwork reduce stress for everyone and help you avoid delays tied to permitting and re‑inspection schedules.
