In September 2019, a Kentfield homeowner named Russell Shaw applied for a permit to replace his sewer lateral. The trigger wasn't a sale. It was a remodel valued above $75,000, one of the thresholds that pulls a property into Ross Valley Sanitary District's compliance system. District staff told him about the grant program right away. Then the permit sat untouched for so long it expired exactly one year later, on September 9, 2020. Shaw had to request an extension before he could even schedule the inspection, which finally happened on January 29, 2021, sixteen months after he first called.
Nobody in that timeline was trying to slow anything down. The gap between "I have a permit" and "I have a certificate" is just wider than most homeowners expect, and it's the same gap that trips up sellers who assume their sewer lateral has to be perfect before a buyer can get keys. It doesn't. That's the part of this rule almost nobody explains correctly.
The Question Everyone Asks Wrong
If you're selling a home in Kentfield, which sits in unincorporated Marin under Ross Valley Sanitary District's jurisdiction, a home sale is one of the events that triggers the district's Private Sewer Lateral Ordinance. So do three other things:
- A remodel or addition valued at more than $75,000
- Adding a bathroom
- Nearby sewer main replacement or road resurfacing work
Sellers hear "sale triggers inspection" and assume that means the lateral has to pass before escrow closes. It doesn't. RVSD does not require the inspection or the repair to happen before you close. The seller and buyer negotiate who handles it, and whoever ends up responsible has 90 days from close of escrow to get it done.
That's a meaningfully different problem than the one most sellers prepare for. You're not racing a repair crew against your closing date. You're deciding, in the purchase agreement, who owns a 90-day obligation that starts the moment title changes hands.
The compliance path itself is straightforward once it starts: a licensed contractor runs a video inspection, the report goes to RVSD as part of a sewer permit application, any needed repairs get made, and a district inspector witnesses a pressure test before issuing the Certificate of Compliance. If the line fails, it gets reinspected. None of that has to happen before your sale records.
Three Clocks, Not One
Here's where things get genuinely confusing, and where a Kentfield seller who's done their homework can look a lot more prepared than one who hasn't. The word "90 days" shows up in this process more than once, and it doesn't mean the same thing each time.
| Clock | Length | Starts when | What happens if you miss it |
|---|---|---|---|
| Compliance repair window | 90 days | Close of escrow (for a sale-triggered inspection) | Whoever agreed to handle it is now out of compliance with the district |
| Grant fund usage window | 90 days | Date RVSD approves your grant application | Approved funds can lapse before you've spent them |
| Grant application submission | 180 days | Date of RVSD's final inspection | You forfeit reimbursement even if the work already passed |
A seller who reads "90 days" once and assumes it always refers to the same deadline is exactly the kind of person who shows up at RVSD's office two weeks before their outside date asking why the grant they thought they'd secured no longer applies. The district isn't being difficult. The clocks are just doing what clocks do, running on their own schedules regardless of whether anyone's tracking all three at once.
What Changed in 2026
If a lateral does need work, the cost math shifted this year in a way worth knowing before you price a repair credit into a purchase agreement.
On April 22, 2026, RVSD's board raised its Lateral Replacement Grant to as much as $3,000 per qualifying property, effective for applications received on or after May 1, 2026. That replaced the district's older two-tier structure of $1,500 and $2,500 grants, so a homeowner quoting an old number from a neighbor or a five-year-old plumber estimate is working from a figure the district no longer uses.
The same board meeting adopted Ordinance No. 76, expanding the Lateral Replacement and Septic-to-Sewer Loan Program. Standard loan limits remain $25,000 for a lateral replacement and $50,000 for a septic-to-sewer conversion, but unique or complex projects can now qualify for up to $60,000, at the district's discretion. If RVSD approves a loan, it pays the contractor directly, and the homeowner repays it through semi-annual property tax installments over ten years, at an interest rate pegged to the 10-year U.S. Treasury rate plus 0.5 percent.
That loan structure carries a detail sellers need to know before they list: these loans are non-transferable. If you sell before the ten-year term is up, the remaining balance has to be paid off at closing, not handed to the buyer. If you or a previous owner used RVSD financing to replace a lateral in the last decade, that's a number your closing statement needs to account for, not a surprise your escrow officer should be discovering in week three.
The Shared Lateral Wrinkle
Kentfield has enough older homes on legacy plumbing that shared, or common, laterals still turn up in title work more often than buyers expect. RVSD treats these as a private matter between the owners who share the line. They're not eligible for the district's grant or loan funding as-is. Owners who disconnect a shared line and build separate, individually compliant connections can qualify for assistance, but the shared line itself sits outside the financial help RVSD offers everyone else.
Multi-unit and HOA-governed properties have their own version of this. In developments where the homeowners' association took on responsibility for shared laterals, RVSD required those associations to bring every lateral under their control into compliance by January 30, 2024. If you're buying or selling a condo or townhome-style property in the RVSD service area, that's a document worth asking for directly, since it tells you whether the association's obligation was already met or is still open.
What This Actually Means If You're Listing
None of this is a reason to panic about a Kentfield listing. It's a reason to do the paperwork chase before you do the photography. RVSD's own key document for skipping a fresh inspection is a valid prior Certificate of Compliance. A folder with an old paid invoice, a permit number, or that certificate can settle the question in a phone call to the district instead of a new camera run.
If the records don't exist or don't cover the current trigger, decide early, and in writing, who is completing compliance and on what timeline. Ordinance dates and dollar figures can shift, as this year already showed, so confirm current numbers directly with RVSD before you build them into a contract. The Shaw permit sat idle for a year for reasons that had nothing to do with malice or bad faith. It's simply how long these things can drift if nobody is actively pushing them forward, and a pending sale is not a natural forcing function the way a remodel deadline sometimes is.
A Short FAQ
Does my Kentfield home's sewer lateral need to pass inspection before I can close? No. RVSD's rule attaches at the sale, but the district gives whoever is responsible 90 days after close of escrow to complete compliance work.
What if my home already had lateral work done? Ask RVSD to check its records before paying for a new inspection. A valid prior Certificate of Compliance on file with the district is the key document for skipping a new one.
Can I use RVSD's grant or loan program if I'm selling soon? You can apply, but read the fine print. Grant funds must be used within 90 days of approval, and loans are non-transferable, meaning any unpaid balance is due at closing if you sell before the ten-year term ends.
What about a shared lateral with a neighbor? RVSD treats shared laterals as a private arrangement between owners and doesn't offer grant or loan funding for them unless the owners disconnect into separate, individually compliant lines.
This kind of local mechanic is exactly why sequencing matters more than speed when you're preparing a Kentfield home for market.
