California Property Taxes: How Proposition 13 Affects What You Pay
Proposition 13 creates a deceptively simple property tax system: 1% of assessed value plus local additions. Here is what you actually pay in year 1 and how the tax changes over time.
The 1% Base Rate and Local Additions
Proposition 13 set California's base property tax rate at exactly 1% of the assessed value. This rate cannot be increased by any means other than a two-thirds voter approval of a specific bond or special assessment. On top of the 1% base, property owners pay: Voter-approved general obligation bonds: school districts, community college districts, water districts, and municipal governments regularly pass bond measures for capital improvements. Each bond adds a small annual assessment to property tax bills. Most properties have 3–8 such bonds, adding 0.1–0.5% total. Mello-Roos Community Facilities Districts (CFDs): created to fund infrastructure for new developments. If your home is in a Mello-Roos district, you pay a special annual tax that can range from $500 to $5,000+ per year. Mello-Roos taxes are not capped by Prop 13 — they are separate assessments that can increase. New construction in California frequently includes Mello-Roos. Total effective rate examples: • Older home in LA city (few bonds, no Mello-Roos): 1.1–1.2% • New construction in Irvine (many bonds, Mello-Roos): 1.6–2.0% • San Francisco condo: 1.0–1.2%
Annual Tax on Common California Purchase Prices
What buyers actually pay in year 1 (assessed at purchase price): • $750,000 purchase in standard suburban CA (1.25% effective): $9,375/year ($781/month) • $1,200,000 purchase in LA suburban (1.2% effective): $14,400/year ($1,200/month) • $2,000,000 purchase in San Francisco (1.1% effective): $22,000/year ($1,833/month) • $1,500,000 purchase in new-build Irvine with Mello-Roos (1.8% effective): $27,000/year ($2,250/month) After 15 years of Prop 13 protection (2% cap, 6% market appreciation): • $750,000 home in 2010 → 2025 assessed: $1,010,000; market: $1,800,000+ • Tax still based on $1,010,000 (at 1.25%): $12,625/year • If new buyer purchased at $1.8M: tax would be $22,500/year • Prop 13 protection saves the long-term owner ~$9,875/year
How to Find Your Mello-Roos Status
For any California purchase, check whether the property is in a Mello-Roos CFD: 1. Ask your real estate agent to pull the full property tax bill from public records. The Mello-Roos assessment will appear as a separate line item. 2. Review the Natural Hazard Disclosure report — it often includes a tax disclosure section that breaks down all annual assessments. 3. Ask the listing agent specifically: "Is this property in a Mello-Roos district?" They are required to disclose. 4. Contact the county tax assessor's office with the parcel number. Mello-Roos status can add $3,000–6,000/year to tax costs for new construction in California. This is a material part of the ownership cost calculation that must be included in any affordability analysis.
“The Mello-Roos surprise is one of the most consistent budget gaps I see with California buyers, particularly those purchasing new construction. A buyer who calculates their tax at "1% of $1.2M = $12,000/year" and then receives a tax bill for $21,000 because the development is in a high-Mello-Roos CFD has been blindsided by something that was entirely discoverable in advance. Always get the full property tax bill breakdown — all line items — before committing to any California purchase.”
