How fractional ownership works, what it costs, where it makes sense, and the places it does not.

Most guides to this subject are advertisements. This one is not.

A tenancy in common (a TIC) lets several households buy one building together, each taking a deeded percentage and the exclusive right to live in one specific unit. In Southern California it is how many people have bought a first home in a neighborhood that had priced them out, typically for 10 to 20 percent less than a comparable condominium.

It is not free money. The mortgage is a bit different and not as easy to obtain. You will make building decisions with three or four neighbors. For some people that trade is obviously worth it. For others it is obviously not.

This guide is built to help you tell which one you are. Every figure is sourced and dated. Where the honest answer is “this concern is correct,” it says so.

What a TIC is not

Not a timeshare, not a co-op, not a condominium. It is a recognized form of real property ownership that California courts confirmed in 2004 and San Francisco has used at scale for more than twenty years. Los Angeles is a younger market, which is both the opportunity and the reason to read carefully.

Why it exists at all

Turning an apartment building into condominiums in Los Angeles means a tract map, multiple agencies and a discretionary approval nobody controls. A TIC needs none of that, because it does not divide land. Months instead of years, and the discount is what that speed costs.

What is tenancy in common?

Four things make a TIC work. Understand these and the rest of this guide follows.

The short version

Several buyers purchase one property together. The deed records what percentage each of them owns. A separate contract, the TIC Agreement, assigns each owner one specific unit, along with the parking, storage and outdoor space that goes with it.

Nothing is subdivided. The county still sees one parcel, one assessor’s number and one tax bill. That is the source of both the advantage (no subdivision approval needed) and every complication that follows from it.

The legal foundation. California courts upheld exclusive-occupancy tenancy in common in 2004. It is settled, not experimental, but it is governed by your contract rather than by statute, which is why the agreement matters so much.

A building of five or more units requires a public report from the California Department of Real Estate before interests can be sold. Four units or fewer requires no state approval at all, only a TIC agreement, which is why most Los Angeles TIC product is four units or under.

Three things that surprise first-time TIC buyers

02

What you actually own

Two documents. One gives you a percentage of a building. The other gives you your home.

The percentage is real property

Your deed is recorded in your name at the county. You can finance it, insure it, sell it, refinance it and leave it to your children. It is not a membership or a share certificate. If you own 26 percent of the building, you own 26 percent of the building.

The agreement is where the value lives

Under ordinary co-ownership law every co-owner may possess the whole property. The TIC Agreement is what converts that into “you live in Unit 3 and nobody else may.” It binds every current owner, every future owner and anyone who ever buys an interest in the building.

Read it before you write an offer. If an agent will not hand it to you, that itself is information.

The clauses that decide everything

• Exclusive occupancy: your unit, parking, storage and yard space
• Your percentage: keyed to relative unit value, not floor area
• Cost sharing: and the property-tax apportionment formula
• Two reserves: capital replacement, and a default reserve for building maintenance and upkeep
• Default remedies: lien, advance-and-recover, forced sale
• Partition waiver: express, or a court can order a sale
• Transfer rules: buyer and lender approval, no further splitting
• Rental limits: which also protect everyone’s financing
• Forced refinance: so one owner cannot hold the group hostage
• Dispute resolution: mediation, arbitration, a buyout mechanic

Condominium vs TIC

The same money buys three different things. Here is the honest comparison, including the rows that favor the other two.

One structural point worth holding on to. You buy at a discount, and the discount tends to carry through to resale. Your appreciation is calculated on the full value of the property, not on the discounted price you paid for it.
