Buying a Home in Sacramento County, CA: Transfer Tax, Flood Zones & Mello-Roos
The City of Sacramento charges its own transfer tax instead of the county rate, and parts of Natomas carry flood-insurance requirements that change parcel by parcel as levee work progresses.
Sacramento County has three things an unrepresented buyer should understand before making an offer: the City of Sacramento layers its own transfer tax on top of the county/state system, large parts of the region (especially Natomas) carry FEMA flood-zone history that affects insurance requirements, and many newer suburban developments carry Mello-Roos special taxes that aren't part of the regular property tax bill.
What’s the transfer tax in Sacramento County?
The county base rate is $1.10 per $1,000 of sale price, but the City of Sacramento is the only city in the county with its own transfer tax — $2.75 per $1,000 — which replaces rather than simply stacks on top of the county share.
Elk Grove, Folsom, Citrus Heights, Rancho Cordova, and unincorporated Sacramento County do not have their own city-level add-on — only the base county/state rate applies there. Who pays is set by the purchase contract, not by law, and is negotiable region-wide.
How does transfer tax actually work inside the City of Sacramento?
Sacramento City Code §3.16.020 sets the city's own rate at $2.75 per $1,000 of sale price, and because the city collects its own tax, the county's base rate does not simply stack on top the way LA's system does.
On a $500,000 home sale inside city limits, the city transfer tax alone comes to $2.75 × 500 = $1,375; the county/state base rate ($550) is waived in favor of the city tax rather than added to it — confirm the exact mechanics with your escrow officer for your specific transaction, since this differs from how most CA cities layer a tax on top of the county base.
Is my Sacramento County property in a mandatory flood-insurance zone?
It depends on the specific parcel, especially in Natomas — FEMA flood-zone status there has changed materially as levee improvement projects have been completed, and not every Natomas parcel has been remapped the same way.
FEMA remapped the Natomas basin to the interim Zone A99 designation (a Special Flood Hazard Area requiring mandatory flood insurance for federally-backed loans) effective June 16, 2015. Since then, the Sacramento Area Flood Control Agency has completed significant levee upgrades, and portions of North Natomas have since been remapped to Zone X (minimal risk, no mandatory insurance) — but not all Natomas parcels have moved. You cannot assume a property's flood-zone status from the neighborhood's general reputation or a nearby property's status. Look up the specific parcel at the FEMA Flood Map Service Center (msc.fema.gov); if it's in a Special Flood Hazard Area (Zone A, AE, or A99) and the loan is federally backed, flood insurance is a mandatory, recurring annual cost, not a one-time fee — and a property that required insurance a few years ago may have since been remapped to Zone X, so verify current status rather than relying on old information.
Are there Mello-Roos taxes in Elk Grove or Rancho Cordova?
Yes — Mello-Roos special taxes are common in Sacramento County's newer suburban developments, particularly in Elk Grove, Rancho Cordova, and parts of Natomas.
These special taxes, formed under the Mello-Roos Community Facilities Act of 1982, fund infrastructure — roads, sewers, parks, sometimes school facilities — for the specific development, and are separate from and not capped by Proposition 13's limit on regular property tax growth. They don't show up if you only look at the base property tax rate. Costs vary widely by specific CFD, with buyers reporting figures in the range of roughly $150–$250/month in some newer Sacramento-area subdivisions and total annual obligations in the low thousands in some Elk Grove developments; duration is typically 20–40 years, set by the specific bond schedule. The seller must disclose an active CFD via a Notice of Special Tax under Civil Code §1102.6b — independently check the county's parcel tax lookup tool and review the preliminary title report for any CFD liens, rather than relying on the disclosure alone.
Is there rent control in the City of Sacramento?
Yes for older units — the Sacramento Tenant Protection Program caps annual rent increases on most pre-February-1995 rental units within city limits, on top of adding pre-eviction procedural safeguards beyond statewide AB 1482.
The program (Sacramento City Code Chapter 5.156, adopted 2019) uses a formula of a 5% base plus the change in California CPI; effective July 1, 2026 the maximum allowable annual increase for covered units is 8.6% (5% base + 3.6% CPI adjustment for that cycle) — the exact percentage resets annually, so verify the current figure. Coverage extends to most residential rental units built before February 1, 1995 within Sacramento city limits, including apartments and duplexes; single-family homes, condominiums, and owner-occupied duplexes are excluded and fall back to statewide AB 1482 only. Landlords who violate the rules can face administrative penalties up to $25,000. Elk Grove, Folsom, Citrus Heights, Rancho Cordova, and unincorporated Sacramento County have no local ordinance beyond AB 1482 as of this writing. If you're buying an older pre-1995 multi-unit property inside Sacramento city limits with existing tenants, review the build date and current lease terms before assuming you can reset rents to market at turnover.
Disclosure landscape
- Because the City of Sacramento's transfer tax may replace rather than stack on the county base, confirm the exact mechanics with your escrow officer rather than assuming a simple add-on.
- Flood-zone status must be checked per parcel via the FEMA Flood Map Service Center, especially in Natomas — remapping following levee work means older information may be out of date.
- A Notice of Special Tax (Civil Code §1102.6b) is required for any active Mello-Roos CFD, common in Elk Grove, Rancho Cordova, and parts of Natomas.
- Rent-cap coverage in the City of Sacramento depends on the building's construction date (before or after February 1, 1995) and whether it's a single-family home/condo — verify rather than assume.
Frequently asked
Do I pay both county and city transfer tax if I buy inside the City of Sacramento?
Not in the simple additive way most CA cities work — the City of Sacramento's $2.75-per-$1,000 rate replaces the county's base share rather than stacking on top of it. Confirm the exact mechanics with your escrow officer for your specific transaction.
Do I need flood insurance to buy a home in Natomas?
It depends on the specific parcel. Some Natomas areas have been remapped from mandatory-insurance Special Flood Hazard Area status to Zone X following levee improvements, but not all have — check the current FEMA flood zone for the exact address before assuming either way.
Is there rent control in Elk Grove or Rancho Cordova?
No local ordinance was confirmed in either city as of this writing — only the statewide AB 1482 cap applies. The City of Sacramento's own Tenant Protection Program (up to 8.6% cap for 2026-2027) applies only within Sacramento city limits.
