Keeping a lawn green in Southern California can cost up to 4,000 gallons of water per month. A native garden in the same climate needs roughly 20. That gap has quietly made the traditional suburban front yard one of the region’s most significant water problems – and one of its most expensive personal habits to maintain.
Water agencies across Southern California have been paying residents to replace thirsty lawns for years, but the scale of current incentives has shifted the conversation from conservation fringe to mainstream financial opportunity. In Los Angeles, the Department of Water and Power offers eligible residential customers rebates of up to $5 per square foot for replacing qualifying turf with drought-tolerant landscaping. Projects between 250 and 5,000 square feet are eligible, meaning a fully approved 5,000-square-foot lawn conversion could qualify for up to $25,000 in rebates, the program’s maximum.
The math behind that number reflects how two rebate programs combine. The Metropolitan Water District of Southern California is offering $2.00 per square foot up to 5,000 square feet of converted yard per year through its SoCal Water$mart portal. The Los Angeles Department of Water and Power (LADWP) adds another $3 per square foot on top of that for its residential customers, bringing the combined total to $5 per square foot. Businesses and residential customers who replace traditional lawns with water-wise gardens can save an estimated 44 gallons of water for every square foot of grass replaced with sustainable landscaping, according to a January 2025 LADWP announcement.
How Much Water the Program Is Actually Saving
Up to 70% of the water used in Southern California goes toward outdoor irrigation. That number shapes why these lawn removal rebates exist at all. Paying homeowners to stop irrigating decorative grass is, from a utility’s perspective, far cheaper than finding new water sources. Metropolitan Water District has for more than 15 years incentivized residents and businesses to replace grass lawns with more water-efficient landscaping, and sustainable landscaping with a water-efficient irrigation system uses up to 80% less water compared to a traditional lawn.
The program’s track record backs that up. Since its start, the Metropolitan Water District Turf Replacement Program has directly resulted in the removal of more than 230 million square feet of grass, according to Metropolitan Water District’s official press release. The water savings from that replacement are large enough to meet the annual demands of more than 83,000 homes. At LADWP alone, the turf replacement rebate program has incentivized the replacement of 55.4 million square feet of turf, saving the equivalent amount of water used by 29,928 homes annually, according to LADWP program data cited in the SoCal Water$mart terms and conditions.
Conversion effects also ripple outward. For every 100 homes that converted their yards using a Metropolitan rebate, an additional 132 nearby homes were inspired to convert their own grass, according to a study cited by Metropolitan Water District – a multiplier effect that no advertising campaign could replicate.
What Qualifies and What Doesn’t
Getting the full rebate requires a specific sequence, and the order matters. The Turf Replacement Program is a two-part application process. In order to receive a rebate, you must apply to reserve rebate funds prior to starting your project. After the reservation, you will have 180 days to complete the project and submit your request for a rebate, according to SoCal Water$mart’s program page.
Starting any demolition before receiving approval is the most common disqualifying mistake. Most programs also require that the replaced lawn meet three design criteria: a minimum number of California Friendly plants per 100 square feet, an upgraded water-efficient irrigation system such as drip or rotating-head sprinklers, and a stormwater retention feature. That stormwater requirement asks for a feature to help keep water in the yard when it rains – rock gardens and rain barrels are among the acceptable elements. The logic is straightforward: water that soaks into the ground on-site is water that doesn’t evaporate off concrete or rush into storm drains.
One substitution that won’t work: artificial turf. Synthetic turf is not an approved conversion option for this program. The intent is living, drought-adapted landscaping – plants that work with Southern California’s climate rather than simply mimicking the appearance of a lawn.
Participants must also commit to maintaining their converted landscapes. Homeowners are required to keep their new gardens meeting program standards for five years after rebate approval. After the reservation is received and approved, you will have 180 days to complete the project.
The Case for Native Plants Beyond the Rebate
The rebate is the financial entry point, but the ongoing savings come from what replaces the grass. Native plants are naturally adapted to California’s climate and survive drought on around 20 gallons of water per month, while keeping a lawn green can take up to 4,000 gallons per month, according to Glendale Water and Power. A well-designed native garden doesn’t just save water – research tracked in the SoCal Water$mart FAQ, drawing on a 9-year Santa Monica comparison study between a traditional turf landscape and a California Friendly one, found that sustainable native gardens use 83% less water and require 68% less maintenance time than traditional gardens.
That lower maintenance translates directly into lower monthly costs. Native plants adapted to local conditions require less mowing, fewer chemical inputs, and far less hands-on upkeep. California Civil Code §4735, as amended by AB 1164, makes any HOA rule requiring turf grass or banning drought-tolerant landscaping void and unenforceable. In other words, even residents in HOA-governed communities can pursue a conversion without fear of fines or rejection – a protection that removes one of the most common reasons people hesitate to act.
Native plants also support something the lawn never did. AB 1164 amended the Davis-Stirling Common Interest Development Act to add explicit protections for drought-tolerant landscaping, reinforcing a broader state policy direction. The California Native Plant Society maintains Calscape, a plant database that documents how yards with at least 70% native plants can provide enough food and shelter to sustain or increase local bird populations, data browsable directly at Calscape. The connection to pollinators, butterflies, and beneficial insects follows the same principle: native species support the ecosystems they evolved alongside, while turfgrass supports very little.
A Law That Changes the Calculus for Commercial Properties
Residential homeowners have a financial incentive to remove their lawns. Starting in January 2027, many non-residential properties won’t have a choice. Non-residential properties in California – such as schools, parks, homeowner associations, and office parks – are prohibited from using potable water to irrigate grass that is not used for recreation or other functional purposes, as noted in Metropolitan’s commercial program page.
The Metropolitan Water District responded to that deadline by doubling its turf rebate for commercial and institutional properties. The agency increased its turf replacement rebate for non-residential property owners to $7 per square foot of grass removed beginning September 2025, according to a Metropolitan Water District press release. The increased rebate was made possible through a $30 million grant from the California Department of Water Resources and $96 million in federal funding through the Bureau of Reclamation’s Lower Colorado Basin System Conservation and Efficiency Program.
For HOAs specifically, the timing matters. Converting common-area grass before the law takes effect means capturing the full rebate rather than being forced into conversion later at full cost. Projects previously approved for Metropolitan’s base rebate of $7 per square foot but not completed by September 30, 2026, will receive $4 per square foot instead – a $3-per-square-foot difference that adds up quickly on large properties.

What to Do Now
The rebate programs are real, well-funded, and active across all six Southern California counties. The process isn’t complicated, but it has a non-negotiable first step: apply before you do anything to your yard. Removing grass before receiving approval disqualifies you entirely, regardless of what you plant afterward.
Applications are completed and submitted online, and rebates are available region-wide through the SoCal Water$mart portal. Los Angeles Department of Water and Power customers apply separately through LADWP’s turf replacement page. Your rebate amount depends on your specific water agency and your project’s square footage, so use the online calculator at socalwatersmart.com to confirm the current figure for your address before starting.
The savings don’t stop when the rebate check clears. Lower outdoor water use cuts monthly utility bills in a region where outdoor irrigation regularly accounts for the majority of residential water consumption. Replacing a traditional lawn with a native garden removes hundreds of dollars in annual maintenance costs – no weekly mowing, no seasonal fertilizer, no sprinkler repairs driven by overuse. The water agencies funding these programs are betting that the math is obvious enough to keep applications coming. For most Southern California homeowners, it is.
