What Is the LMD Assessment on a Santa Clarita Tax Bill?

You see an LMD assessment on a Santa Clarita property tax bill, or it appears in the documents for a home you’re considering. The line is a special assessment for services provided within a particular Landscape Maintenance District zone. It isn’t a charge that applies to every home in the city, and the City’s pages don’t call it a Mello-Roos tax.

The assessment generally supports landscaping and related improvements serving properties in that zone. Because Santa Clarita’s zones are financially independent, the zone number matters when you review a home, its tax bill and its recorded documents.

This is general information and not legal advice.

What does the LMD assessment pay for?

The LMD assessment pays for landscaping and related features serving slopes and common areas within a specific zone.

According to the City of Santa Clarita, a Landscape Maintenance District is a special assessment district established to fund and maintain landscaping and appurtenances for slopes and common areas. The City places the assessment on annual Los Angeles County Assessor property tax bills and administers the collected funds.

Those funds can cover mowing, weeding, trimming and fertilizing plant material. They can also pay utility costs such as water and electricity, along with scheduled and unscheduled repairs, reserve funding and administration.

The eligible work isn’t limited to plants. Funds may be used for enhancements and select hardscape features, including stamped concrete medians, concrete paseos, post rail and wrought iron fencing, irrigation controllers, pedestrian bridges and tunnels, lighting, and play equipment.

Santa Clarita’s Special Districts division manages 2,000 acres of landscaping in 62 financially independent zones, plus 18,500 street light poles and an urban forest of 100,000 trees. These totals describe the division’s broader responsibilities, not the services assigned to every parcel.

Why does the zone matter?

The City’s LMD Zones page lists zones by number and name. Examples include T-2A Skyline Ranch, T-48 Shadow Hills, T-62 Canyon Heights, T-44 Bouquet Canyon, 15 River Village, 32 Vista Canyon Ranch, and 20 and 21 Golden Valley Ranch. The page lists zone 2, Cinema Parkway, as inactive. Zone 2008-1, Major Thoroughfare Medians, contains all medians on major thoroughfares in the city.

A letter T before the zone number means Los Angeles County originally created that zone. It was later annexed by the City. Every zone remains financially independent, so you shouldn’t use one neighborhood’s assessment or service details as a stand-in for another’s.

The City says special assessment revenues fund enhanced services that benefit particular properties. Those benefits are unique and distinctive from services generally provided elsewhere in the city.

How is an assessment calculated and approved?

An LMD assessment is generally calculated from the zone’s costs and allocated among parcels according to the special benefit provided to each property.

The City says assessments are generally calculated while a development is in its planning stage. Either the City or a developer may propose a special landscape benefit assessment. The calculation considers annual maintenance, repairs, utilities such as water, reserve funding and administration.

The assessment is then spread among parcels based on the degree of special benefit that the landscape improvements provide to each property. A rate methodology accounts for different property uses.

The Santa Clarita City Council holds a public hearing every June to review and approve recommended special assessment amounts for the operating year beginning July 1. After approval, the assessments appear on the annual property tax bill generated by the Los Angeles County Assessor.

Once a maximum assessment has been established, the City cannot increase it without approval from the property owners. That owner approval process distinguishes a proposed increase to the maximum from the annual City Council review.

What happened in three zones in 2025?

In 2025, the City began an owner information and balloting process concerning proposed assessment increases in three neighborhood zones.

A March 27, 2025 City press release identified Zone T-62 Canyon Heights, Zone T-48 Shadow Hills and Zone T-44 Bouquet Canyon. The City said owners in those zones were paying annual assessments that had remained unchanged for many years. It also said rising maintenance and utility costs meant the existing rates were no longer sufficient to cover ongoing expenses.

Four informational meetings were planned for April 23, April 30, May 15 and May 29, 2025. The scheduled topics included the current assessment structure, proposed adjustments, the balloting process and potential alternatives. Affected owners were to receive a letter by mail.

As of November 6, 2026, the ballot result is not established in the source material reviewed for this guide. Do not assume that any of the three assessments increased or decreased. Check the City’s LMD pages, the applicable June City Council hearing record and the property’s current tax bill for the recorded outcome.

What can an LMD easement mean for a yard or fence?

An LMD easement can give the City access to maintain covered landscaping on private property, which can limit where a fence may be placed.

The City’s LMD FAQs say a developer generally records a landscape maintenance easement on the property’s title as a condition required by the City. The easement allows the City to enter the property to maintain the landscaping in perpetuity.

A fence in that area could interfere with maintenance or access to slope swales. The swales direct runoff during rain, and the easement supports a consistent planting palette across property lines.

The recorded document matters because the City’s general description doesn’t establish the boundaries for a particular property. Buyers and sellers should review the recorded easement and compare it with any planned fence or yard work.

What should buyers and sellers check?

Buyers and sellers should verify the zone, tax bill line items, recorded easement and applicable Engineer’s Report for the specific parcel.

Start with the annual property tax bill. Look for the assessment as its own line item instead of assuming it is included in another tax or charge. A property tax bill can also carry other items, and the California supplemental property tax bill guide explains one that follows a purchase. Then use the City’s “What Zone Am I In?” residency look-up or GIS map linked from the LMD Zones page.

Ask the City’s Special Districts office for the Engineer’s Report tied to the identified zone. The contents of those reports were not reviewed for this guide, so no assessment dollar amount is stated here.

If the property also has an association, the California HOA disclosure guide covers a different set of documents. An HOA and an LMD should not be treated as interchangeable merely because both may relate to shared-area maintenance.

A Santa Clarita buyer found an LMD assessment on the tax bill and assumed it was a temporary charge left by the developer. We explained that the Landscape Maintenance District assessment helped fund specified local maintenance and needed to be treated as an ongoing ownership cost unless the records showed otherwise. We included it when recalculating his monthly budget.

Who handles maintenance questions and emergencies?

The City handles LMD matters inside Santa Clarita. The County of Los Angeles Department of Public Works is responsible for LMD areas outside the city limits, including Castaic, Val Verde and Stevenson Ranch.

Inside the city, landscape contractors do not act directly on a homeowner’s request. Use the City’s Resident Service Center for non-emergency requests. Report vandalism to the Sheriff’s Department and graffiti to the City graffiti hotline.

If a tree from an LMD common area falls onto a fence or roof and presents imminent danger, call 911. Without a continued threat, contact the Special Districts division for tree removal at its 24-hour hotline, (661) 290-2200.

For trees on an LMD slope, the City says it will work with residents to maintain view sheds when possible. That isn’t a promise to trim or remove a tree for a view, and tree topping is not an accepted arboricultural practice.

The short version

An LMD assessment is a zone-specific special assessment that funds landscaping and related improvements benefiting parcels within that zone.

Not every Santa Clarita property pays one. If a charge appears on the tax bill, identify the LMD zone, review the bill’s individual line items, ask the City’s Special Districts office for the zone’s Engineer’s Report and check the title report for any recorded landscape maintenance easement. The City Council reviews recommended assessments every June for the operating year beginning July 1, while an increase to an established maximum requires property-owner approval.
