Las Virgenes Municipal Water District: A Buyer's Due-Diligence Guide

If you are buying in Calabasas, Hidden Hills, Agoura Hills, or Westlake Village, your water comes from LVMWD — and its budget-based rates can surprise large-lot owners.

Direct AnswerThe Las Virgenes Municipal Water District (LVMWD) supplies water to roughly 70,000 residents across Calabasas, Hidden Hills, Agoura Hills, and the western Conejo Valley including Westlake Village. LVMWD uses a budget-based tiered rate structure: each property gets a water budget based on factors like household size and irrigated area, and usage above that budget is billed at higher tiers. For large-lot and estate buyers, over-tier surcharges can be a meaningful, easily overlooked carrying cost.

How budget-based water rates work

Rather than a flat rate, LVMWD assigns each parcel an efficient water budget and charges progressively higher prices above it. A large lawn, pool, or mature landscaping on an estate parcel can push a household into the highest tiers.

What to verify before you buy

Request recent water bills, confirm the irrigated-area budget is correct, and factor expected usage into carrying costs — especially for estates in Calabasas and Hidden Hills. Drought rules have eased, but the budget framework remains.

Recycled water and reliability

LVMWD operates the Tapia Water Reclamation Facility and a recycled-water system used for irrigation in parts of the service area, which can lower outdoor-watering costs where available.
