Mello-Roos in Simi Valley

Which neighborhoods have it, how much it costs, and why the sticker price on a Big Sky home is not actually cheaper than a same-priced Wood Ranch home.

Updated: April 2026
Quick Answer

Mello-Roos is a California special tax that funds infrastructure (schools, roads, sewers) in newer developments. In Simi Valley, Mello-Roos commonly appears in Big Sky, portions of Long Canyon, portions of Wood Ranch, and newer Sycamore Grove construction. Annual assessments typically range from $1,200 to $6,000 and last 20 to 40 years from the district formation date.

What Mello-Roos is

The Mello-Roos Community Facilities Act of 1982 allows local governments to create Community Facilities Districts (CFDs) that impose special taxes on property owners to fund infrastructure. When Big Sky, Long Canyon, and portions of Wood Ranch were developed, CFDs were formed to finance the schools, roads, water systems, and parks serving those areas. The special tax assessments pay off the bonds that built that infrastructure.

Mello-Roos is not a property tax in the traditional sense. It is a special assessment tied to the parcel regardless of who owns it. When you buy a Mello-Roos property, you inherit the remaining assessment. When you sell, the next owner takes over.

How it affects your mortgage math

A $3,500 annual Mello-Roos is about $292 per month. At current rates, that is the equivalent of roughly $47,000 in additional loan principal, because a $47K extra loan at 6.75% costs about $305 per month. Translated: if you are choosing between a $900K Big Sky home with $3,500 Mello-Roos and a $947K Wood Ranch home without Mello-Roos, the monthly cost is nearly identical.

This is why ignoring Mello-Roos when comparing neighborhoods is a serious buyer mistake. The sticker price looks lower, but the monthly carrying cost is comparable to a more expensive but Mello-free home.

How to verify Mello-Roos

Check the Ventura County Assessor's Office online property tax records for the current annual assessment. Your agent can also request it from the listing agent. During escrow, you will receive a formal Mello-Roos disclosure listing current and remaining obligations.
