Mello-Roos in Irvine, by village

Mello-Roos is a special tax that pays for the streets, parks, storm drains and schools a new neighborhood needs before anyone lives in it. California passed the law in 1982, in response to Proposition 13, to give cities and school districts a way to pay for that growth. The legal name is a Community Facilities District, or CFD. A CFD sells bonds to build things up front, and the homes inside it repay them through a special tax on the county property tax bill every year.

In Irvine you'll run into three kinds of these charges. The city has three true Mello-Roos districts, and the largest by far is CFD 2013-3 in the Great Park. The city also has assessment districts under the state's 1913 and 1915 improvement acts, which is how most villages since the mid-1990s financed their streets and utilities, usually at the Irvine Company's request as the landowner. Irvine Unified and Tustin Unified run their own Mello-Roos districts for schools in newer neighborhoods. All of them land on the same tax bill, and most people call every one of them Mello-Roos.

So the real answer depends on the village, and in the newer villages on the tract. The oldest villages mostly carry none of these charges. A home in Woodbury or Quail Hill can carry a city assessment and a school tax at the same time.

From the 1990s on, most new Irvine villages had their streets and utilities financed through city assessment districts. The city describes the process plainly: the Irvine Company, as the landowner about to develop a village, typically asked for a district to cover the upfront costs. Bonds sold to investors paid for the work, and each lot repays its share through a yearly assessment on the county tax bill. The city's current list pairs each district with its village.

Many of these homes also pay Irvine Unified a school Mello-Roos tax on a separate line. Its CFD 01-1, which the district's state filings call South Irvine Communities, covers Quail Hill, Shady Canyon and Turtle Ridge, and its bonds are scheduled to be paid off on September 1, 2038. When the school board refinanced them in 2024, it kept that date and didn't extend the levy. Woodbury pays CFD 04-2, split into two improvement areas, whose bonds were first sold in 2006 and now run through September 2036.

Some older assessment groups have already been paid off, and a district's bonds were often sold in groups as each phase was built. That's why two streets in one village can stop paying in different years, and why I don't trust a village-wide answer about the end date.

Homes in the Great Park Neighborhoods, built on the former El Toro Marine Corps air station, pay the special tax of Community Facilities District 2013-3. The city formed it in 2013 with the master developer, Heritage Fields El Toro, to pay for backbone streets, utilities, storm drains, parks and trails, along with building and maintaining the Great Park itself. Affordable units are exempt, and residents get priority access and discounts at park facilities because they pay into the district.

The district is split into improvement areas, each with its own rates and bonds, and the neighborhoods have their own: Pavilion Park is Improvement Area 1, Beacon Park is 4 and Parasol Park is 8. In Parasol Park the tax follows the home's size and type, not its value. For scale, the 2018 bond papers there listed 2018-19 special taxes from about $4,600 a year for an attached home of 1,200 to 1,399 square feet up to about $9,200 for a detached house of 2,950 to 3,199 square feet. The maximum can go up by as much as 2 percent a year.

Then there's the part that never ends. The city says the bonds typically take 40 years to repay, after which the charge drops by roughly 65 to 82 percent and the rest continues in perpetuity for maintenance. In Parasol Park the 2 percent increases run through fiscal 2058-59. After that about three quarters of the tax ends, and the services part that stays can rise 3 percent a year. Only the part that ends can be paid off early.

Dates can move. In 2024 the city refinanced Pavilion Park's 2014 bonds and raised about $20 million for projects in the district, partly by moving the final maturity from 2049 to 2054. The city has said future bond sales won't raise the charge. On school taxes, the overlapping debt table in the 2018 Parasol Park bond papers lists water district bonds and no school Mello-Roos district.

A Mello-Roos tax is voted in before most homes are sold. When fewer than 12 people have been registered to vote inside a proposed district, which is normal on raw land, the landowners vote instead, with one vote per acre, and the tax needs two thirds of the votes cast. In practice the developer approves it and every later owner inherits it, because the tax is secured by a lien recorded against the property.

The amount isn't tied to what the house is worth. State law calls it a special tax rather than an assessment and lets the district split it by any reasonable formula. For a home, the maximum can rise by no more than 2 percent a year, and the part that pays for facilities needs a last tax year, set when the district is formed. A tax for ongoing services can be set to run with no end date.

A city assessment works differently. Under the 1913 and 1915 acts, each lot carries a fixed lien for its share of the improvements, and the state constitution limits that share to the special benefit the lot actually gets. The lot repays it in yearly installments on the tax bill until the bonds are repaid, and then the line drops off.

Not every extra line on an Irvine bill is one of these. Measure E is a voter-approved school bond charged on assessed value, and the 2018 Great Park bond papers also show Irvine Ranch Water District taxes there that are based on the value of the land. Neither is Mello-Roos.

Start with the current bill, which you can pull up at taxbill.octreasurer.gov. Mello-Roos taxes and assessments sit under Special Assessment Charges, where Orange County now prints the actual name of the district's bond, and the bill lists a phone number for each agency that levies one.

For a map, use the county's OC Tax Map at taxmap.octreasurer.gov. You can search by address or click around the map, and it shows the base levy and every special charge on a parcel, Mello-Roos included, with the agency's number. For CFDs it can also show the original year, the bond term and what the district pays for. I don't know of an official Mello-Roos map for Irvine alone: the city lists its districts by village name and the school districts keep their own records, so this parcel-by-parcel county map is the closest thing.

Then ask for the official notices. On a resale the seller has to make a good-faith effort to get one from every agency that levies a Mello-Roos tax or a 1915 Act assessment on the home. The agency has five working days to send it and can charge up to $15 for a Mello-Roos notice or $10 for an assessment notice. The Mello-Roos notice gives the maximum tax, how fast it can grow and the last tax year for facilities, plus any services tax that can run forever. The state's forms also say a buyer can cancel the contract within three days of receiving the notice in person, or five days after it's mailed. On a new home, the builder has to give you the notice to sign before you sign the purchase contract.

Two gaps to know about. An assessment notice doesn't give an end date, so for a city district I call the city at 949-724-6000, ask for Fiscal Services and find out when that parcel's bonds are paid off. And the disclosure law doesn't require the agents to discover a district they didn't know about, which is why I pull the bill myself instead of waiting for the disclosure package. In Tustin Unified's part of north Irvine, the lookup at specialdistricttransparency.com/tusd gives a parcel's current tax, its CFD number and the final year of the tax.
