Ask any relocation buyer what they want to hear on a Montecito disclosure packet, and "connected to public sewer" usually tops the list. It sounds finished. No septic tank to inspect, no drain field to worry about, no leach line easement to untangle before closing. For most of California, that assumption holds.
Montecito is currently the exception.
The Montecito Sanitary District, the agency that bills roughly 3,185 properties across an 8.9 square mile service area, just locked in a five year schedule of rate increases at the same time its own board can't agree on who should run it. If you're underwriting a purchase here based on the idea that "on sewer" means a settled, boring line item, the last six months of district meetings say otherwise.
What the June Vote Actually Locked In
On June 10, 2026, the Montecito Sanitary District's Board of Directors unanimously adopted a new sewer rate schedule, the first change since 2019 and the first comprehensive rate study the district has done in nearly a decade. The new rates took effect July 1, 2026, and they run through fiscal year 2031, with the board authorized to raise the charge by as much as 14 percent every year for five straight years.
Before this increase, a single family home in the district paid $1,480 a year for sewer service, with condos and second dwelling units billed at $696. That baseline was already the highest in the immediate area. For comparison, single family sewer charges elsewhere on the South Coast run closer to $530 a year in Goleta, $810 in Santa Barbara, and $825 in Carpinteria, with Summerland the one neighbor charging more at roughly $1,351.
The district says the increase is necessary because it identified $60 million in capital improvements needed over the next five years, much of it tied to a treatment plant built in 1961 that's now showing its age. General Manager John Weigold told the board that every month the district delays those projects adds another $250,000 to the eventual cost.
Board President Rock Rockenbach framed the 14 percent figure as a limit, not a promise:
"These rates are ceilings, they are not floors."
That's an honest way to put it, and it cuts both directions. The district isn't committing to the maximum every year. It's also not committing to anything less.
Why the Board Setting This Bill Can't Agree on Its Own Future
Rate increases are one story. Governance is the other, and it's arguably the more important one for a buyer trying to gauge how stable this cost really is.
In April 2026, a memorandum of understanding drafted by the Montecito Water District came up for a vote at the Sanitary District board, proposing to fold the sanitary district into a single consolidated agency governed by the water board. Two directors, Woody Barrett and Dorinne Lee Johnson, voted to approve it. Two others, Rockenbach and Carter Ohlmann, voted no, arguing they couldn't agree to what amounted to dissolving the sanitary district under someone else's governing body. The vote tied 2-2 and failed.
That vote happened two hours after Vice President Dana Newquist resigned, citing time constraints. He was the fourth sanitary district director to step down in four years. The board appointed Montecito resident John Murphy, founder of Montecito Capital Finance and a 30 year veteran of mortgage lending and capital markets, to fill the seat in May. Murphy's appointed term runs only through December 4, 2026, and three seats on both the water and sanitary boards are up for election that November, meaning the composition that will decide how aggressively future rate increases get applied is still an open question as of this writing.
None of this is a scandal. It's a small, five member special district working through a genuine disagreement about its own structure, and both sides have made reasonable arguments in public meetings. But it does mean the rate path a buyer sees today assumes a governing board that has changed four times since 2018 and may change again in a matter of weeks.
The Connection Fee Nobody Mentions Until the ADU Plans Are Drawn
If you're buying with plans to add a guesthouse, a detached ADU, or a significant addition that requires a new connection to the district's system, there's a separate number worth knowing before you pencil out the budget. The district's connection fee has stood at $8,400 per dwelling unit since a 2018 board resolution. Given that the district is now mid-stream on a $60 million capital plan and has openly discussed sending its wastewater to the City of Santa Barbara for treatment instead of upgrading its own plant, a study the board approved spending $110,000 to pursue, that fee is one more variable worth confirming directly with the district rather than assuming it's fixed indefinitely.
What This Means If You're Comparing Montecito to Somewhere Else
Here's the part that changes how a buyer should actually think about this. In most coastal California markets, the due diligence burden runs toward septic. You ask about tank age, pumping records, drain field capacity, because septic systems are private infrastructure and the owner carries the risk. Sewer connections are treated as the safe, low maintenance default because a public agency owns the pipe and the plant.
In Montecito right now, that logic only partly holds. Yes, if a system fails, it's the district's plant and the district's problem, not yours directly. But the district's own board just spent a year debating whether to exist in its current form, its rates are already the highest on the South Coast, and it has committed itself to five years of increases specifically because it can't currently afford to maintain its own infrastructure without them. A property inside the sanitary district's 8.9 square mile boundary carries a cost trajectory that's now written into county tax bills through 2031, collected the same way property taxes are collected, and subject to annual board review rather than a single fixed number.
Some Montecito parcels, particularly at higher elevations or outside that service boundary, still rely on private septic systems, which puts them on an entirely different track: California's Transfer Disclosure Statement requires sellers to disclose the type of sewage disposal system serving a property, and a septic parcel brings its own separate set of inspection and maintenance questions that have nothing to do with the sanitary district's rate schedule.
Neither path is inherently worse. They're just different risks, and the sewer connected path is no longer the one that requires zero follow up questions.
Questions to Ask Before You Write the Offer
- Is this parcel inside the Montecito Sanitary District's service boundary, or does it rely on a private septic system?
- If it's sewer connected, what is the current annual sewer service charge on the most recent property tax bill, and has that owner protested or challenged any rate increase?
- If you're planning an ADU or a major remodel that requires a new connection, is the $8,400 per unit connection fee still current, and does the project trigger any additional district review?
- If it's on septic, when was the system last inspected and pumped, and is there documentation on file with the county?
A Few Direct Answers
Does every property in Montecito pay the sanitary district's sewer charge? No. The district's service area covers 8.9 square miles and roughly 3,185 properties. Parcels outside that boundary, including some at higher elevations, rely on private septic systems and are not subject to the district's rate schedule at all.
Is the 14 percent figure guaranteed every year? No. The district's board describes 14 percent as the maximum it's authorized to charge in a given year, not a fixed annual increase. The actual rate is set through board review each year through fiscal year 2031.
Could the rate structure change again before 2031? It's possible. Three seats on the sanitary board and three on the water board are up for election in November 2026, and the two agencies have an unresolved history around consolidation. A different board could revisit both the pace of increases and the broader governance question.
The specifics here matter less than the habit they point to. A well priced Montecito home can still carry a cost structure that isn't visible until someone asks the right question of the right agency. That's precisely the kind of groundwork Maureen McDermut and her team walk buyers through before an offer goes in, not after. If you're evaluating a property in Montecito and want a clear read on what's actually behind the number on the tax bill, schedule a private consultation.
