Two attached homes on two Claremont streets can look identical from the sidewalk and require completely different insurance. The difference is not architectural. It is what the owner actually OWNS, and that is a question the recorded documents answer, not the elevation.
Owners who get this wrong tend to get it wrong in one of two expensive directions: buying a small walls-in policy for a home whose structure nobody else insures, or buying a full policy that duplicates what an association already carries.
This article extends the Claremont home insurance guide. It explains a distinction in ownership form and how it relates to insurance in general terms. I am a real estate professional, not an insurance broker and not an adjuster. Nothing here states what any policy or any association document covers. Coverage questions belong to a licensed insurance broker and to the carrier in writing, association questions belong to the association and its documents, and consumer questions belong to the California Department of Insurance. Verify current terms before relying on any of it.
Two ownership forms wearing the same clothes
In the common condominium form, the owner typically owns a defined interior space plus an undivided interest in common area. The building itself is generally an association responsibility, insured under a master policy, and the owner's own policy is built to cover what the master does not. That structure is described in the article on what a walls-in policy covers.
In the planned-development form, the owner often owns the lot and the structure standing on it, even when that structure shares a wall with the neighbor's. The association may maintain landscaping, private drives, a pool and other common facilities, and may insure those. The house itself can be the owner's to insure, in full.
Both are commonly called townhomes in conversation. Only the documents distinguish them.
How to find out which one you have
THE DECLARATION. The governing document sets out what is separately owned and what is common. It is the primary source and it is available to owners and, during a purchase, in the disclosure package.
THE MAP. A condominium plan and a subdivision map describe different things. Whether the parcel is a lot with a building on it, or an airspace unit within a building, is visible there.
THE ASSOCIATION'S EVIDENCE OF INSURANCE. Associations carry insurance and can produce a summary of it. The question to ask is precise: does the association's coverage extend to the STRUCTURE of the individual homes, and if so, to what point.
The answer to that last question is what determines what an owner needs, and the sensible move is to hand all three documents to a licensed broker rather than describing the property over the phone.
The two failure modes
UNDERBUYING. An owner in a planned development buys a walls-in policy because a neighbor across town has one. If nobody else is insuring the structure, the structure is uninsured. This is not a small gap, and it is the kind of gap that tends to be discovered at the worst possible moment.
OVERLAPPING. An owner in a true condominium buys a full dwelling policy on a building the master policy already covers. Money is spent, and the presence of two policies aimed at one structure does not make a claim simpler.
Neither error is exotic. Both come from answering an application question by appearance rather than by document.
The middle cases, where care is required
Real communities are not always tidy. An association's obligation can extend to the exterior surfaces but not the interior, or to the original construction but not later improvements, or to some structures on the property but not others. Detached garages, carports, patio covers and fencing are frequent sources of ambiguity, and the general question of what counts as another structure is treated in the article on other structures coverage.
Where an association's coverage stops short of a loss, owners can face a shared charge, which is why the article on loss assessment coverage is relevant to attached-home owners in both forms, not only to condominium owners.
A deductible on the association's policy is its own topic and worth asking about explicitly, alongside the owner's own deductible structure described in the article on separate deductibles by peril.
Doing this during a purchase
The disclosure package in an attached-home purchase contains the governing documents and usually evidence of the association's insurance. That package arrives early for a reason.
The practical sequence is to send the declaration and the association's insurance summary to a broker at the same time as the address, so the quote being produced is for the right kind of policy. A quote for the wrong form is not a comparison, it is a distraction, and it can conceal a real placement problem until late in escrow. The article on binding coverage in escrow sets out the wider timing.
A lender will also have a view. Where an association carries the structure, lenders often want evidence of the master policy as well as the owner's policy, which is another reason to gather the documents rather than reconstruct them at the end.
The Claremont angle
Claremont's attached housing was built across several decades and in more than one legal form. There are true condominium projects and there are planned developments whose homes share walls but sit on their own lots. Age matters too: older communities may have governing documents that have been amended more than once, and the current amended version is the one that governs.
The practical instruction for a Claremont owner or buyer is the same in every case. Do not answer the ownership question from the street. Read the declaration, get the association's evidence of insurance, and let a licensed broker say which structure of policy the property actually calls for.
Where I stop
I can explain why the ownership form drives the insurance form, and which documents settle it. I cannot tell anyone what an association's policy covers, what their own policy should be, or how a particular claim would be handled. Those belong to the association and its documents, to a licensed insurance broker, to the carrier in writing, and to the California Department of Insurance.

Frequently asked questions
Is a townhome insured like a condo?
Not always. The ownership form decides it. In a condominium the association commonly insures the building and the owner insures the interior and contents; in a planned development the owner may own and insure the structure itself. Read the declaration and confirm with a licensed broker.
How do I find out which form my home is?
The governing declaration, the recorded map or condominium plan, and the association's evidence of insurance together answer it. During a purchase these arrive in the disclosure package.
What happens if I buy the wrong type of policy?
Buying a walls-in policy where nobody else insures the structure can leave the building uninsured. Buying a full dwelling policy where the association already covers the structure can mean paying for overlapping coverage. Both are avoidable by checking the documents first.
Does the association's insurance cover my detached garage or patio cover?
It depends entirely on the governing documents and the association's policy. Detached structures, fencing and patio covers are common areas of ambiguity, so ask the association in writing and give the answer to your broker.
Who should review this before I close?
A licensed insurance broker, working from the declaration and the association's insurance summary rather than a description of the property, plus your lender for what evidence they require. This article is orientation from a real estate professional, not insurance advice.
