The escrow officer slides a preliminary title report across the table, and the buyer's eye catches a line she has not seen anywhere in the listing photos or the HOA disclosure packet handed over during the tour. It reads something like "Direct Charges: Special Assessment" and a dollar figure that has nothing to do with the monthly HOA statement she budgeted around. She calls her agent. The agent explains that in Calabasas, the HOA fee is one of at least three separate bills tied to the same parcel, and only one of them is set by the community she thought she was buying into.
This happens often enough in Calabasas escrows that it is worth explaining before you write an offer, not after you open a title report.
Most buyers comparing gated Calabasas communities treat the HOA fee as the ceiling of what living behind the gate costs beyond the mortgage. It is not. Three distinct charges can show up on or around a Calabasas property, each billed by a different entity, on a different schedule, governed by a different set of rules.
The first is the HOA due itself, set by the homeowners association board and used for landscaping, security staffing, and shared amenities. This is the number that appears in marketing materials and the one buyers ask about first.
The second is a Mello-Roos special tax. Calabasas has two active Community Facilities Districts on the Los Angeles County secured tax roll, one formed in 1998 and listed as CFD 98-1, and one formed in 2001 and listed as CFD 2001-1. These districts were created under California's Community Facilities Act to fund public infrastructure that the base 1 percent property tax could not stretch to cover after Proposition 13 capped how fast that base tax could grow. The special tax is not based on your home's value. It rides with the parcel, gets set by a formula fixed when the district was formed, and shows up as its own line on the county tax bill, separate from anything the HOA collects.
The third is a city landscape and lighting assessment. Calabasas maintains five landscape districts covering more than twenty separate assessment zones, and these charges are billed by the city, not the HOA, even when the zone overlaps almost exactly with a gated community's boundaries. For fiscal year 2025-26, the most recently published per-parcel rates ran $1,018.78 for The Oaks of Calabasas, $1,460.57 for Calabasas Park Estates, and $2,191.01 for Westridge. Those numbers fund brush clearance, irrigation repair, and common-area landscaping inside the same streets the HOA already maintains, which is exactly why they get mistaken for HOA dues and rarely are.
| Community | HOA due (monthly, approximate) | City landscape assessment (FY2025-26, annual) | Mello-Roos CFD |
|---|---|---|---|
| The Oaks of Calabasas | $450 to $650 | $1,018.78 | On county roll, separate from base tax |
| Calabasas Park Estates | $250 to $350 | $1,460.57 | On county roll, separate from base tax |
| Westridge | Varies by section | $2,191.01 | On county roll, separate from base tax |
Read the table the way a buyer comparing two listings actually should. Calabasas Park Estates carries a lower HOA due than The Oaks, but a higher landscape assessment. Westridge sits highest on the landscape line of the three despite generally lower price points than The Oaks. None of these three numbers move together. A community with modest HOA dues can still carry a heavier city assessment, and a Mello-Roos parcel tax follows the fixed formula set when its district was created rather than tracking either one. The only way to know the true stack for a specific address is to pull the parcel-specific figures, not to assume the HOA fee tells the whole story.
There is a fourth cost that never appears on any bill until it is too late to plan around, and The Oaks of Calabasas is the community that learned this the hard way.
Brian Cameron was the first resident of The Oaks and later spent eighteen years on its HOA board. In the year following the community's transition from developer control to homeowner control, he came back onto the board and found the reserve fund had dropped from $400,000 to $40,000, the result of the prior board dipping into reserves to cover operating shortfalls. The HOA brought in Association Reserves, the reserve-study firm founded by Robert Nordlund, to rebuild a funding plan and restore the kind of hard data that lets a board defend its fee decisions to skeptical homeowners and, eventually, a judge.
The lesson for a buyer is not that The Oaks is risky today. It recovered, and its current general manager credits regular reserve studies with keeping homeowner trust intact. The lesson is that a healthy-looking HOA statement in one calendar year says nothing about the reserve fund behind it, and a community that underfunds reserves for years can hit a special assessment that dwarfs anything on the monthly bill. That risk sits entirely outside the HOA fee, the Mello-Roos tax, and the landscape assessment, which is exactly why it is the easiest of the four to miss.
A list price and an HOA fee are not enough to compare two homes on equal footing. Before you treat either number as final, work through these steps.
None of this makes Mello-Roos or a landscape assessment a reason to walk away from a Calabasas home. These mechanisms fund real infrastructure and real upkeep. The point is that the sticker HOA fee was never designed to capture all of it, and a buyer who only asks about that one number is pricing the property on a fraction of its true carrying cost.
Does every Calabasas gated community have a Mello-Roos tax? No. Only parcels within the boundaries of Calabasas CFD 98-1 or CFD 2001-1 carry the charge, and coverage varies by community and even by section within a community. The only reliable way to confirm status is to check the specific parcel's secured tax bill.
Is the city landscape assessment the same everywhere in Calabasas? No. The city maintains five separate landscape districts across more than twenty assessment zones, and rates differ by zone. The figures cited here reflect fiscal year 2025-26, the most recently published rates for The Oaks, Calabasas Park Estates, and Westridge specifically, so confirm the current levy before relying on them for budgeting.
Can Mello-Roos or a landscape assessment ever go away? A Mello-Roos special tax can end once the bonds it secures are paid off, though some districts continue collecting for ongoing maintenance afterward. Landscape assessments tend to be more permanent, since they fund recurring upkeep rather than a bond with a fixed payoff date. Either way, treat the current rate as the number to plan around rather than assuming it will shrink.
Comparing two Calabasas homes on price alone leaves out most of what it actually costs to own one. If you want the parcel-specific numbers pulled and explained before you write an offer, or you are weighing The Oaks against Calabasas Park Estates, Westridge, or Greater Mulwood and want a straight answer on what each carries beyond the HOA statement, Jonathan Burstein can walk through the full stack with you and help you compare listings on equal footing.
