"CCPH does NOT require OSS pumping as part of inspection compliance. Pumping is a maintenance action. In addition, only pumping the system does not meet the inspection requirement." That sentence is on Clark County Public Health's non-compliance fee page, and it is where many acreage sales around Battle Ground start to go wrong.
A seller can have a pumping receipt from last spring and still be out of compliance. A seller can have a clean inspection from fourteen months ago and still lack the document the county expects before listing. Most of a septic-served sale runs on dates, and in the autumn three of them stack up together: the one-year window for a current report, the county's December 31 compliance cutoff, and the lag between an inspection and the county's record of it. A home listed in October runs into all three at once.
The one-year clock is tied to the sale date
Clark County Public Health asks realtors and homeowners to make sure a current Report of System Status is on file before a home is listed. The county defines "current" as completed within one year of the date of sale. Your routine inspection cycle is a separate thing. The report has to be current for the closing.
The difference matters when a listing runs long. An inspection done in late 2025 may have been perfectly current when the house went on the market. If the home sits through the holidays and closes in spring 2027, that same report can fall outside the window before signing day.
The routine inspection cycle runs on its own schedule. Clark County sets it by system type:
| System type | Routine inspection interval |
|---|---|
| Conventional gravity and pump-to-gravity | Every three years |
| Pressure distribution | Every two years |
| Advanced systems | Every year |
A gravity system inspected 30 months ago can be fully compliant with the county's routine schedule and still have no report current enough for a sale. Owners of advanced systems are on an annual cycle anyway, so they are less likely to be caught out.
Checking takes a few minutes. On the county's Property Information Center, you search by address or tax account number and open the Environmental tab. That tab holds as-built drawings showing where the system sits, the original permit, and links to inspection reports filed through OnlineRME going back to November 2007.
Why December 31 matters for an October listing
In 2025 the Clark County Board of Health approved a non-compliance fee for on-site sewage systems. The rule is specific. Any system more than one year past its required inspection date as of December 31 gets the fee added to the next year's property tax bill. The county's own example is a system due on December 30, 2024 and still uninspected on December 31, 2025, which is assessed on its 2026 taxes.
The 2026 Environmental Public Health fee schedule lists the standard annual operating permit at $13.87 and the non-compliant operating permit at $24.48. On their own, those amounts are small. The trouble is that the fee appears on a property tax bill, and a tax bill is something title, escrow and the buyer's side all read. A small line item becomes a question during closing.
Here is how the calendar looks from today, October 8, 2026:
- Now through November. A certified inspector has to be scheduled. Clark County publishes its list of certified inspectors, and only people certified by Clark County Public Health may inspect, pump, maintain, repair or install a system here.
- The two-week gap. The county warns that inspectors can take up to two weeks to report an inspection to Public Health. To avoid the fee, the inspection must be completed and reported before December 31. An inspection done the week before Christmas may not reach the county in time.
- A new county system. Clark County's environmental public health permitting and inspection data system went offline May 11–17, 2026, and a replacement launched Monday, May 18, as ClarkCountyToday reported in April. The septic program page still says processing may take longer than expected while staff learn the new system. The county has published no backlog figure. It has only said publicly that processing is slower.
- January 1, 2027. The state seller disclosure form changes, as explained below.
A seller who books an inspection in October gets a report that is current for a sale well into 2027, is reported comfortably ahead of the December cutoff, and leaves time for a slower county system. A seller who waits until December is working against all three deadlines.
When an inspection finds a failure inside city limits
Everything above concerns paperwork. An inspection can also find that the system has failed, and inside Battle Ground city limits that can turn into a sewer connection.
Battle Ground Municipal Code 13.120.010 states the city's aim to have its sewer system used "to the maximum extent possible" and treats buildings within city limits as part of the area it serves. The code lists exceptions to connecting. One covers an existing septic system that becomes inoperable, but only when the building is more than 600 feet from an existing sewer line or lateral. Within 600 feet, that exception does not apply. The code also sets out other exceptions and appeal provisions. Its history shows an amendment by Ordinance 26-09 on May 18, 2026.
The cost difference is significant. Clark County estimates a residential septic replacement at $7,000 to $15,000. The city's 2026 fee schedule, effective January 1, 2026, sets the sewer system development charge at $15,701 per ERU inside city limits and 1.5 times the in-city rate outside them. That charge comes before any private construction. The code makes the property owner responsible for the sewer lateral.
| Item | Figure | Source and period |
|---|---|---|
| Private septic inspection | $200 to $500 | Clark County estimate |
| Annual operating permit | $13.87 | Clark County, 2026 schedule |
| Non-compliant operating permit | $24.48 | Clark County, 2026 schedule |
| Septic replacement | $7,000 to $15,000 | Clark County estimate |
| Sewer SDC, inside city limits | $15,701 per ERU | City of Battle Ground, 2026 |
| Sewer SDC, outside city limits | 1.5 times in-city rate | City of Battle Ground, 2026 |
Two limits apply to this. The 600-foot rule is written for premises within city limits, and the sources reviewed for this piece do not confirm that it reaches properties that are only inside Battle Ground's urban growth area. The city's push west toward Dollars Corner was still under Clark County review as of September 2026. ClarkCountyToday reported that a change to the growth area would not, on its own, shift infrastructure responsibility to the city. Separately, Clark Regional Wastewater District says it serves the rural centers of Meadow Glade and Hockinson near Battle Ground. The district also cautions that its maps do not determine service availability for any single parcel. Who provides sewer to a given address, if anyone does, can only be confirmed address by address.
The well runs on the lender's terms
Many of the same rural properties draw water from a private well, and the well paperwork runs on its own timeline.
On the state seller disclosure, known as Form 17, sellers answer whether the household water comes from a private well, whether a written shared-well agreement or water-source easement exists, whether repairs are needed, and whether potable water has been adequate all year. On a shared well, buyers' attention usually lands on the agreement question, because the answer depends on paperwork the seller may never have looked for.
Testing is less settled than many sellers expect. The Washington Department of Health's private well guidance recommends testing every year for coliform bacteria and nitrate, and testing for arsenic in both summer and winter because levels can change with the season. The department treats nitrate in excess of 10 mg/L and arsenic above 0.01 mg/L as exceeding drinking water standards. The same guidance says a county department or lender may require results during a sale, and it directs owners to confirm local requirements. The research for this piece found no Clark County rule requiring a well test at every sale, so the tests a transaction needs usually depend on the buyer's loan.
That puts the well's timeline in the lender's hands. A septic report can stay current for close to a year, but which water tests a loan calls for, and how long a result stays usable, are set by the loan program and the lender. Those terms are settled with the buyer's lender during the transaction, not with the county.
The form changes on New Year's Day
A listing that runs past year-end also moves onto a revised disclosure form. Under chapter 173 of the 2026 session laws, Form 17 adds an environmental question on January 1, 2027, asking whether the property includes a family burial ground, mausoleum or columbarium. An earlier 2026 amendment from the common-interest-community resale certificate law took effect June 11, 2026. Neither change touches septic or wells. On rural acreage, though, the new burial ground question is one more item to answer on a form whose wording changes partway through a winter listing. The current text of RCW 64.06.020 shows both versions.
Short answers
Does pumping the tank before listing count as an inspection? No. The county calls pumping maintenance and says pumping alone does not meet the inspection requirement.
How can a buyer see a home's septic history? Search the address in the county's Property Information Center and open the Environmental tab. It holds permits, as-builts and inspection reports going back to November 2007. If documents are missing, Public Health can be reached at 564-397-8428.
Is help available to pay for a repair or a sewer connection? Clark County Public Health lists financial assistance for repair, replacement or sewer connection through Craft3, Clark County Community Services, the USDA and local public sewer providers. Eligibility varies.
