Replacing Your Lawn in San Diego: Options, Rebates and Rules

Quick answer

Most San Diego homeowners who replace a lawn choose a mix of low-water plants on drip irrigation, permeable hardscape and, where a lawn is still useful, a lower-water grass. Turf replacement rebates have been offered through regional and local water agencies, but amounts and funding change often and many programs have required approval before you remove any grass. Check with your water agency before you start.

A green lawn is one of the thirstiest things you can grow in a place that averages about 10 inches of rain a year. That is why so many San Diego homeowners have taken out some or all of their grass over the past decade, and why water agencies have paid people to do it at various times. Replacing a lawn can lower your water bill and your maintenance time, but the results vary a lot depending on what you put in its place and how it is installed. This guide walks through the choices, the rules and what drives the cost.

First, decide what the space needs to do

Start with how you use the yard, not with a plant list. Ask yourself:

Do kids or dogs need a soft area to play? If so, keeping a smaller patch of lawn, or a tough groundcover, may make sense.
Is the front lawn only decoration? Front yards are often the easiest place to swap grass for low-water planting.
Do you want more places to sit, eat or walk? Some of the lawn might become patio or paths.
How much maintenance do you want? A well-designed native garden needs less mowing and water, but it still needs weeding, pruning and irrigation checks.
Are you in a fire hazard area? Plant choice and placement near the house matter more if you border canyons or open space.

The main replacement options

Low-water planting on drip

This is the most common choice. Mediterranean-climate plants and California natives such as toyon, lemonadeberry, Cleveland sage, deer grass, California fescue and coffeeberry handle the long dry season once established. Plants are grouped by water need and watered with drip lines, which put water at the roots instead of spraying it into the air or onto the sidewalk. Mulch covers the soil between plants to hold moisture and keep weeds down, though combustible mulch should be kept out of the first five feet around a house in a fire hazard area.

A smaller or lower-water lawn

If you want some grass, you can keep a smaller lawn where it is actually used, or switch grass types. Tall fescue is the most common lawn in California, but University of California, Riverside trials found warm-season bermudagrass needed noticeably less irrigation to stay acceptable through summer. Warm-season grasses go tan in winter, especially in inland areas. Groundcovers sold as lawn alternatives are another option; the UC Master Gardener Program of San Diego County has written about several of them.

Permeable hardscape

Decomposed granite, gravel, flagstone set in gravel and permeable pavers create paths and sitting areas that need no water and let rain soak in. Large areas of bare rock can get hot in inland summers, so most designs combine hardscape with plants and shade.

Artificial turf

Synthetic turf uses no irrigation water, but it is not maintenance free, it can get very hot in direct sun, and it does not let the soil support plants or wildlife. Many rebate programs have excluded it; the County of San Diego's own turf replacement program says artificial turf is not eligible. HOAs and cities may also have rules about it.

Rebates: what to know before you remove anything

Turf replacement rebates in San Diego County have come from several places over the years: the regional SoCal WaterSmart program run through the Metropolitan Water District, the San Diego County Water Authority and its member agencies, some individual cities and water districts, and, for some unincorporated properties, the County of San Diego's Waterscape program. Amounts, size caps and rules have changed often, and programs have run out of funding quickly in drought years.

Because the details change, we don't list amounts here. Instead, before you sign a contract:

Find out which agency supplies your water. It is on your water bill.
Check that agency, the San Diego County Water Authority and SoCal WaterSmart for current turf replacement and irrigation rebates.
Read the requirements carefully. Programs have commonly required approval before any grass is removed, minimum plant coverage, a permeable surface, and irrigation changes such as converting spray heads to drip.
Take before photos and keep receipts.
Ask your landscaper whether they have worked on rebate projects and who will handle the paperwork.

Rules that can apply

Watering rules. City of San Diego customers may water landscapes only before 10 a.m. or after 6 p.m., with no runoff and no watering during or within 48 hours after measurable rain. Other agencies set their own rules, and new plants still need establishment water within them.
Water-efficient landscape ordinance. California's Model Water Efficient Landscape Ordinance (MWELO), as adopted by your city, generally applies to rehabilitated landscapes of 2,500 square feet or more and new landscapes of 500 square feet or more when the project needs a permit, plan check or design review. Most single front-yard swaps are smaller, but ask your designer.
HOA approval. Many master-planned communities in Chula Vista, Carlsbad, Oceanside and elsewhere require architectural review before landscape changes. California law has limited HOAs' ability to ban water-efficient landscaping, but they can still review designs, so get approval in writing.
Contractor license. Landscaping work of $1,000 or more in labor and materials, or any job needing a permit, requires a CSLB contractor license. Plants, sod, irrigation and patios are all on CSLB's list.
Digging. California law requires contacting DigAlert (811) at least two working days before digging.

How the work is usually done

Kill or remove the grass. Running grasses such as Bermuda and kikuyu are hard to kill and will come back through mulch if they aren't fully removed or treated. Ask how the company will handle them. Sheet mulching, solarizing and physical removal are common methods, each with trade-offs in time and cost.
Redo the irrigation. Spray heads are capped or converted, and drip lines are laid for the new plants. A weather-based controller is often added.
Shape the ground. Gentle swales or basins can hold rain on the property instead of letting it run to the street.
Plant and mulch. Plants go in at the right depth, ideally in fall, then mulch covers the soil.
Establish. Even drought-tolerant plants need regular water for their first year or two.

What drives the cost

We don't quote local prices, because costs depend heavily on site conditions. The biggest factors are:

Size of the area and how the grass is removed
How much irrigation has to be changed or replaced
Plant sizes; small container plants cost far less than large ones and often catch up quickly
Hardscape such as paths, patios and edging
Soil prep, grading and any drainage work
Access for equipment and haul-off of old turf and soil
Rebate requirements, which can add design or documentation steps

Get written, itemized estimates from more than one licensed company and compare plant counts and sizes, irrigation details and warranties, not just the total. Never pay more than 10 percent down or $1,000, whichever is less, unless the contractor has a bond on file that allows more.

Bottom line

Replacing a lawn works best when it is planned as a whole: what the space is for, which plants suit your coastal or inland microclimate, how the irrigation will change, and whether a rebate applies. Check your water agency's current programs first, then work with a licensed company that has done this kind of project before.

Frequently asked questions

Is there a rebate to remove my lawn in San Diego?

Turf replacement rebates have been offered through SoCal WaterSmart, the San Diego County Water Authority, local water agencies and, for some unincorporated properties, the County of San Diego. Amounts and funding change often, and programs have commonly required approval before removal. Check with your water agency first.

Does artificial turf qualify for rebates?

Often not. The County of San Diego's turf replacement program says artificial turf is not eligible, and many water agency programs have excluded it. Check the current rules of the program you plan to use.

Can my HOA stop me from replacing my lawn with low-water plants?

California law limits HOA bans on water-efficient landscaping, but HOAs can still review and approve designs. Submit plans to your HOA and get approval in writing before work starts.
