Buying a Condo in Silicon Valley: What to Check First

Buying a condo in Silicon Valley is a different transaction from buying a house, and most of the risk sits in documents people skim. The building matters more than the unit.

A single-family home is mostly a question about the property and the street. A condo adds a third party you cannot negotiate with and cannot leave: the homeowners association. It sets your monthly cost, controls the roof over your unit, decides when the building gets repaired, and can bill you for that repair whether or not you agree with it. Two identical units in two different buildings can be very different purchases.

The good news is that California gives you an unusually strong right to inspect all of this before you commit. The Davis-Stirling Common Interest Development Act requires the seller to provide a substantial package of association documents. Most buyers glance at it. The ones who read it are the ones who do not get surprised.

Read the reserve study before you read the listing again

A reserve study is the association’s engineering and funding plan for everything it will eventually have to replace: roof, elevators, plumbing risers, siding, decks, boilers, paving. It estimates remaining useful life for each component and how much cash the association should be holding to meet it.

The number to look for is percent funded — reserves on hand as a share of what the study says should be on hand. A well funded association has been collecting steadily for the work it knows is coming. A poorly funded one has been keeping dues artificially low, which feels like a bargain right up to the moment the roof reaches end of life and the cost arrives as a special assessment split among the owners. That assessment can run into five figures per unit, it is not optional, and it does not care that you bought last month.

Low dues are not a feature on their own. Dues that are low because the building is small, simple, and has few shared systems are genuinely cheap. Dues that are low because the association is deferring maintenance are a bill you have not been handed yet.

The documents that decide whether this is a good building

• Reserve study — component list, remaining useful life, and percent funded. Read the funding section, not just the summary.
• Two to three years of board meeting minutes — the single most revealing document in the package. Disputes, leaks, insurance problems and assessment debates appear here long before they appear anywhere official.
• Current budget and the last completed financial statement — is the association operating at a deficit, and how much is actually going into reserves each month?
• CC&Rs, bylaws, and rules — what you may do with your own unit: renovation, pets, parking, and whether renting it out is allowed at all.
• The insurance certificate — what the master policy covers and, crucially, where it stops. That boundary determines what your own HO-6 policy needs to pick up.
• Pending litigation disclosure — active construction defect or insurance litigation can affect both your risk and your lender.
• Any special assessment already levied, approved, or under discussion.

Rental restrictions are a resale question, not just a lifestyle one

Many associations cap the share of units that may be rented out. If you are buying to live there, that can look irrelevant. It is not. A rental cap narrows the pool of future buyers to owner-occupants and investors who happen to arrive while a slot is open, and it interacts with financing in ways that matter on exit.

Note also that California law has moved on parts of this. Legislation in recent years has limited how far associations may restrict accessory dwelling units and rentals in certain circumstances, and the boundaries have shifted more than once. Do not rely on an old copy of the CC&Rs to tell you what is enforceable today — ask for the current rules and, where real money depends on the answer, ask a real estate attorney.

Condo financing has an extra gate

With a house, the lender underwrites you and the property. With a condo, it also underwrites the association. Lenders and the agencies behind them look at owner-occupancy ratio, the share of dues that are delinquent, how much of the building one entity owns, adequacy of reserves, and pending litigation. A building that fails those tests can be difficult to finance conventionally even when the buyer is immaculate.

This is worth establishing early rather than late. Ask your lender to review the association package as soon as you have it. Discovering a financing problem during escrow costs you leverage, time, and sometimes the deposit protections you would have had if you had asked sooner.

Property tax will not stay at the seller’s number

Under Proposition 13, a property is assessed at its base year value, the base tax rate is one percent of assessed value plus voter-approved local rates and any special assessments, and the assessed value may rise no more than two percent per year while ownership is unchanged. A sale is a change of ownership, which triggers reassessment to market value.

The practical consequence catches first-time buyers constantly: the tax figure on the listing reflects the seller’s base, which may be decades old. Yours will be based on what you paid. You will also receive a supplemental tax bill covering the difference for the remainder of the tax year, separately from your regular bill and often after you have already moved in. Budget for it before it arrives.

If the building sits in a Mello-Roos Community Facilities District, there is an additional special tax to fund infrastructure, and it is not capped by the Proposition 13 two percent limit. It must be disclosed. Read that disclosure and add the number to your monthly figure.

What a Silicon Valley condo is actually good at

The honest case for a condo here is proximity and predictability of effort. You are buying a shorter commute, a smaller maintenance burden, and a building that handles the roof so you do not have to. For someone whose time is the scarce resource, that is a real trade and often the right one.

The honest case against is control and correlation. You do not decide when the building spends money, and your household finances are somewhat tied to a local employment base that is concentrated in one industry. Both of those are fine if you have looked at them squarely. Neither is fine if you find out afterwards.
