Buying a Home in Madera County, CA: Transfer Tax, Tesoro Viejo CFDs & Expanding Fire Maps
Madera County's foothill growth boom near Millerton Lake comes with real Mello-Roos and expanding fire-map exposure — here's what buyers should check.
Madera County sits between the San Joaquin Valley floor and the Sierra Nevada foothills, with Millerton Lake (formed by Friant Dam on the San Joaquin River) marking much of its southern border with Fresno County. The county combines valley-floor agricultural land with a genuine foothill growth boom — large master-planned communities like Riverstone and Tesoro Viejo — in the Rio Mesa area southeast of the city of Madera.
What’s the transfer tax in Madera County?
Madera County's rate is flat across the entire county at $1.10 per $1,000 of consideration, with no city — the City of Madera or Chowchilla — imposing an additional surcharge on top.
Both incorporated Madera County cities sit at the same combined $1.10/$1,000 total — the standard $0.55 county + $0.55 city split, not an add-on. On a $350,000 sale, that's $385 in transfer tax anywhere in the county.
Which Madera County developments have Mello-Roos?
The City of Madera has two established Community Facilities Districts, CFD 2005-1 and CFD 2006-1, and the county has separately used Mello-Roos financing for large Rio Mesa-area master-planned communities — a CFD was formed for Tesoro Viejo (CFD No. 2021-1, "Tesoro Viejo II").
County board records from 2022 show the special tax on that district's original territory ceasing to be levied while the county pursued annexing additional territory into a new district — CFD boundaries and special-tax status in a fast-building community like Tesoro Viejo or Riverstone can change year to year as new phases are annexed. Confirm current CFD status and the specific special-tax amount directly for any parcel in these developments; California Civil Code §1102.6b requires the seller to make a good-faith effort to obtain and deliver a Notice of Special Tax before close.
Is foothill new-construction near Millerton Lake at wildfire risk?
Yes, and the mapped risk is expanding — a June 2025 CAL FIRE map update (the first update to 'high' and 'moderate' local-responsibility-area designations since 2011) added roughly 400,000 acres of new fire hazard severity zone coverage across the greater Fresno-Clovis-Madera area, including new 'moderate' designations for parts of Tesoro Viejo itself.
Portions of Tesoro Viejo north of the Madera Canal, along with several unincorporated subdivisions near Millerton Lake, were already mapped in CAL FIRE's high or very-high zones before this update. Don't assume foothill new-construction is exempt from meaningful fire risk just because it's newly built — check the specific parcel against CAL FIRE's current Fire Hazard Severity Zone viewer, since the map itself has recently expanded in this area. Also confirm well/septic status (common outside municipal service areas) and road-maintenance responsibility for the private roads common in newer rural foothill subdivisions.
What should I know about buying near active farmland in Madera County?
Madera County is a significant agricultural producer, particularly for almonds, grapes, and other San Joaquin Valley row and tree crops, and remains an active Williamson Act participant unlike Imperial County.
Confirm Williamson Act agricultural-preserve contract status before assuming unrestricted development rights on valley-floor rural-adjacent land, and expect normal agricultural operations (dust, spraying, truck traffic) near active farmland.

Frequently asked
Is there a city transfer tax add-on in the City of Madera or Chowchilla?
No. Both cities sit at the same flat $1.10 per $1,000 combined rate — no city-level surcharge anywhere in the county.
Does Tesoro Viejo have a Mello-Roos special tax?
A CFD (No. 2021-1, "Tesoro Viejo II") was formed for the development, though 2022 county records show the special tax on its original territory ceasing while new territory was annexed. CFD status and levy amounts shift as the community builds out — confirm the current figure directly for any specific parcel.
Did fire hazard maps recently change near Millerton Lake or Tesoro Viejo?
Yes — a June 2025 CAL FIRE update added roughly 400,000 acres of new hazard-zone coverage across the greater Fresno-Clovis-Madera area, including new 'moderate' designations for parts of Tesoro Viejo. Check the current map for any specific parcel rather than relying on an older designation.
Can I freely develop agricultural land in Madera County?
Not necessarily — confirm Williamson Act agricultural-preserve contract status before assuming unrestricted development rights on valley-floor rural-adjacent land.
