Why Carmel Highlands Buyers Can't Assume the Septic Tank Got Checked

Ask a seller in Monterey, Pacific Grove, or Carmel-by-the-Sea about their sewer lateral, and there's already a paper trail. Those cities require a point-of-sale inspection before escrow closes, and so does the Carmel Area Wastewater District for the parcels it serves. The inspection happens whether anyone asks for it or not.

Cross Highway 1 into Carmel Highlands and that paper trail disappears. Most of the Highlands sits in unincorporated Monterey County, running on private septic systems rather than a public sewer line, and county Environmental Health staff have been direct about what that means at closing: pumping and inspecting the tank is recommended, not required. Nobody has to look at it before you sign.

That gap would be a minor footnote almost anywhere else. In the Highlands, it isn't, because the state agency responsible for policing this exact stretch of coastline has already put its own concern in writing.

What the Coastal Commission actually found

In a staff report filed in November 2025 concerning a property enforcement case on Spindrift Road, California Coastal Commission staff described the Highlands in terms buyers rarely see in a permit filing. The report is blunt: the Carmel Highlands is "known to have problematic septic systems, with many residences in need of replacements" to keep effluent out of coastal waters.

That sentence appears in a document resolving a specific violation, not a general survey, but it reads like an admission that the pattern is bigger than one parcel. In this case, the property owner had already replaced the septic tank as part of settling the violation, and staff treated the upgrade as a genuine improvement to coastal water quality, not just a box to check. The same filing tied the resolution to something else entirely: an offer to eventually open a locked beach access path to public use.

That second detail is worth sitting with, because it shows how tangled Highlands real estate can get once the Coastal Commission is involved. A septic fix and a beach access easement, folded into one case.

The beach access fight sitting behind the septic story

The path in question runs to Yankee Point Beach, one of two ways down from Spindrift Road, and for decades it's been open only to members of the Carmel Highlands Association through a locked gate. When Coastal Commission staff floated the idea that the property owner might eventually dedicate that path for public use, in exchange for resolving the same violation tied to the septic replacement, the Association's current president, Glenn Berry, filed a formal objection. His argument leans on history: the exclusive easement dates to 1921, and generations of use by Association members have reinforced that private status, not weakened it.

This isn't the first time a Spindrift Road easement has drawn a Coastal Commission fight over Yankee Point access. A separate case from 2019 involved a different parcel on the same road, owned by Darla Harbaugh, where a nonprofit called the Mal Paso Creek Property Association, representing roughly 225 properties from Yankee Point south to Granite Creek since its founding in 1968, objected on similar grounds. Their position was that neither the Commission nor an individual homeowner could unilaterally offer up an easement that legally belongs to the two property associations as a group.

Neither of these disputes involves your specific listing, most likely. What they show is a pattern: in the Highlands, a permit problem on one lot can pull in questions about beach access, easement history, and neighborhood association authority that have nothing to do with the house itself. It's a reminder that Coastal Commission attention here rarely stays narrowly focused on the parcel under review.

Further back, a 2013 case makes the same point from a different angle. A Highlands property at 105 Highway 1, built by the architect Charles Sumner Greene between 1918 and 1922, sought Coastal Commission approval for a private tunnel connecting the house to a small beach below. The Commission blocked it, citing habitat protections and a policy against extensive landform alteration along that stretch of coast. More than a decade later, that same regulatory posture, careful, slow, and skeptical of anything that alters the bluff, is exactly what shows up again in the 2025 septic case.

What this means before you write an offer

None of this changes the legal minimum. Monterey County still doesn't require a septic inspection before closing in the Highlands. What it does mean is that skipping one is a real risk, not a formality, given what the Coastal Commission's own files say about the housing stock here.

A few practical notes worth knowing before you're in contract. County Environmental Health points to a low-tech way to confirm what you're dealing with: a septic-served property typically has a 4-inch PVC cleanout sticking out of the ground near the house, and no recent sewer bill. If you're buying a Highlands parcel closer to the inland edge near existing sewer infrastructure, county code also requires any plumbed structure within 200 feet of an approved sewer line to connect to it rather than rely on septic, so it's worth confirming which side of that line a given lot falls on before assuming septic is even an option long term.

For sellers, the math runs the other way. If your system hasn't been pumped in years, ordering that inspection before you list does more than protect a future closing date. It gives you a number to work with instead of a guess, and it keeps a buyer's own late-discovery inspection from becoming a re-trade conversation two weeks before close.

A few questions worth asking directly

Does every Carmel Highlands property use septic? Most do, since the neighborhood is largely unincorporated, but some parcels near sewer infrastructure may be required to connect under county code. Confirm status parcel by parcel rather than assuming.

If the county doesn't require an inspection, can I still request one as a buyer? Yes. Nothing stops a buyer from ordering a septic inspection during the contingency period, and given what the Coastal Commission has documented about the area, it's a reasonable ask regardless of what the listing says.

Does the Yankee Point Beach access dispute affect resale value? It depends entirely on the parcel. Properties tied directly to the disputed easement carry more uncertainty than ones with no connection to that access path. An agent familiar with the specific lot lines in that stretch of the Highlands can tell you quickly whether it's relevant to a given listing.

Are septic replacements expensive enough to affect negotiations? Costs vary by system size, soil conditions, and permitting, and county Environmental Health can provide current fee schedules for permits. The point isn't a specific number, it's timing: finding out during due diligence gives you leverage that finding out after close does not.

Carmel Highlands rewards buyers and sellers who look past the view and into the paperwork, and that's exactly where local, specific knowledge earns its keep. If you're weighing a purchase or a sale on this stretch of coast and want someone who already knows which Spindrift Road disputes matter and which don't, Alex Brant is a native of this Peninsula and can walk the specifics with you before you're deep in escrow.
