In Lafayette, the monthly cost of a home goes well beyond the mortgage. The tax bill carries local school parcel taxes and a sewer charge, insurance is shaped by wildfire mapping, and hillside lots bring their own upkeep.

Here is what to add up before you settle on a price range in this luxury market.

How are property taxes figured on a Lafayette purchase?

Under Proposition 13, your purchase price generally sets the new assessed value, and the base tax is about 1 percent of that plus any voter-approved bond rates for the area. After closing, expect a supplemental tax bill for the difference between the old and new assessed values.

I explained that bill in the property tax bill nobody warns you about, and if you are 55 or older and moving from another California home, see how Prop 19 can carry your tax base.

What parcel taxes and charges appear on the bill?

Lafayette's tax bills include flat charges on top of the ad valorem tax. For example, Lafayette School District voters approved Measure H on June 2, 2026, a parcel tax of $585 per parcel per year for nine years, with a senior exemption, according to the district. The district has other voter-approved parcel taxes as well.

Sewer service from the Central Contra Costa Sanitary District is billed as an annual charge on the county property tax bill for most owners. Ask the seller for the current tax bill and read every line.

How does wildfire risk affect insurance?

Parts of Lafayette are hillside and wooded, and the State Fire Marshal maps Fire Hazard Severity Zones statewide. Look up the address on the state's map, and get an insurance quote early in escrow. In higher-hazard areas, insurers may ask about roofing, vents, defensible space and access, and some buyers end up needing the California FAIR Plan plus a separate policy.

I walked through the disclosure and insurance side in wildfire hazard zones in Clayton; the same questions apply in Lafayette.

What upkeep should you budget for?

  • Trees and vegetation on larger lots, including clearance for defensible space.
  • Drainage and retaining walls on sloped lots.
  • Older systems, since many Lafayette homes are older.
  • Remodel costs and approvals, which take longer in hillside areas. See building or buying new near Lamorinda.
