Estimate owner's and lender's title insurance premiums for San Mateo and Santa Clara County home purchases — and understand who pays in each county.
Rates are based on California filed rate schedules for major title underwriters and reflect typical Peninsula transactions. Your actual premium may vary.
Who pays for title insurance is one of the most frequently misunderstood differences between the two primary counties on the Peninsula. The difference is material: on a $2.5M home, the owner's title policy alone can run $5,000–$8,000.
| Item | San Mateo County | Santa Clara County |
|---|---|---|
| Owner's Policy Premium | Seller traditionally pays | Buyer traditionally pays |
| Lender's Policy Premium | Buyer pays (if getting a loan) | Buyer pays (if getting a loan) |
| Escrow/Settlement Fee | Split 50/50 is most common | Split 50/50 is most common |
| Preferred Underwriter | Fidelity, First American, Chicago Title (all active) | Fidelity, First American, Chicago Title (all active) |
| Standard Policy Form | CLTA (standard); ALTA for jumbo/luxury | CLTA (standard); ALTA increasingly common for $2M+ |
| Negotiability | Customs are negotiable in the contract; seller's market = customs typically hold | Same — customs hold in competitive markets |
Title insurance protects against defects in the chain of title — problems with ownership history that could threaten your right to the property after you buy it. The title company searches recorded documents going back decades (deeds, liens, judgments, easements, covenants) and issues a commitment to insure. The policy covers you if an undiscovered defect surfaces: an unknown heir with a claim, a forged deed in the chain, an unrecorded easement, an improperly released lien. Unlike other insurance, the premium is a one-time payment at close. The owner's policy protects you for as long as you own the property; the lender's policy protects your mortgage lender and expires when the loan is paid off.
In San Mateo County, the seller traditionally pays for the owner's title policy, and the buyer pays for the lender's policy if they are financing. In Santa Clara County, the buyer traditionally pays for both the owner's policy and the lender's policy. These are customs, not laws — the purchase agreement is the actual governing document and both parties can agree to any allocation. In a competitive seller's market (which the Peninsula has been for most of the past decade), these defaults tend to hold. In a softer market or when a buyer has significant leverage, it is not unusual to negotiate for the seller to contribute toward or pay for the buyer's title costs.
CLTA (California Land Title Association) is the standard owner's policy and covers defects that appear in the public record: liens, encumbrances, prior ownership disputes. ALTA (American Land Title Association) is the extended coverage policy that adds protection for survey-related risks: boundary disputes, encroachments, and certain unrecorded matters that a property survey would reveal but the recorder's files would not show. ALTA is more comprehensive and costs 10–25% more than CLTA. On the Peninsula, ALTA is increasingly common for properties over $2M and is frequently required by lenders on jumbo transactions. Buyers in Woodside, Portola Valley, Los Altos Hills, and hillside communities with complex boundary histories often benefit most from ALTA coverage; buyers of condominiums in well-established urban developments typically do fine with CLTA.
Endorsements expand your base policy's coverage for specific risks. Common ones on the Peninsula: the 116 Endorsement (confirms the improvements are where you think they are relative to lot lines), the 103.7 Endorsement (confirms no violation of recorded CC&Rs at close), the ALTA 5 or CLTA 111.5 (PUD endorsement for planned unit developments and HOAs), and the Eagle or Comprehensive endorsement (broader coverage, popular on luxury transactions above $3M). For buyers in Woodside, Portola Valley, or hillside properties with well issues or shared access roads, ask your title company specifically about endorsements covering those risks. Endorsements typically add $50–$600 each and are well worth the cost when they apply to your specific property.
Yes, though in practice the seller's choice of title company (or the agent's preferred escrow relationship) often drives the selection in San Mateo County, where the seller typically places the order. In Santa Clara County, where the buyer frequently pays for both policies, buyers have more practical leverage to choose their provider. The major underwriters on the Peninsula — Fidelity National, First American, Chicago Title, Stewart, Old Republic — file their rates with the California Department of Insurance, so premium differences between underwriters are modest (typically under 5–10%). The more meaningful differentiator is service quality and local expertise; a title company that handles large volumes of San Mateo or Santa Clara County transactions will flag local issues (recorded easements, specific local disclosure requirements) faster than a generalist. Ask your agent for a recommendation based on specific transaction experience, not just the name.
