The sticker price comparison looks lopsided: sod is $1.50–$3 per sq ft installed. Artificial turf is $11–$18. End of story, right?

Not in San Diego. The 10-year math tells a different story once you add water, mowing, fertilizing, repairing patches, and the inevitable full reseed when drought restrictions hit.

Here’s the real comparison for a 500 sq ft backyard.

Year-one cost

Sod: $1,000 (materials + install). Plus prep — soil amendment, irrigation if needed. Realistic landed cost $1,500–$2,500.

Artificial turf: $5,500–$9,000 installed. Done.

Sod wins year one. By a lot.

The water bill

San Diego sod needs roughly 30–50 gallons per square foot per year to stay green in our climate. For 500 sq ft, that’s 15,000 to 25,000 gallons annually.

San Diego County water rates run roughly $7–$10 per HCF (748 gallons). That puts the water bill at $140 to $335 per year for a 500 sq ft sod lawn.

Artificial turf needs roughly 1–2 gallons per sq ft per year for hose-rinses. About $5 in water per year for the same yard.

10-year water bill:

  • Sod: $1,400 to $3,350
  • Turf: $50

Maintenance

Sod:

  • Mowing — every 1–2 weeks, March through November. Either you do it (your time) or pay $30–$60/visit. At $40/visit × 24 visits/year × 10 years = $9,600 if you hire it out.
  • Fertilizer — $80–$150/year × 10 = $800–$1,500
  • Aeration + thatching — $200/year × 10 = $2,000
  • Sprinkler system maintenance and repairs — average $300/year × 10 = $3,000

Artificial turf:

  • Annual hose-rinse and brush — DIY, basically free
  • Optional professional cleaning — $250 once a year if you want it. $2,500 over 10 years.
  • Infill top-up around year 5 — roughly $400.

10-year maintenance (paid out, not DIY):

  • Sod: $15,400 to $16,100
  • Turf: $0 to $2,900

If you DIY sod maintenance, the dollar cost drops but you’re putting in 50+ hours per year of weekend labor. That’s its own number.

Replacement / repair

Sod degrades. Drought stress, pet damage, kids’ wear lanes, pest issues, fungal disease — within 5–7 years most San Diego sod lawns need a full reseed or partial resod. Budget $1,500–$3,000 every 5–7 years.

Artificial turf with proper install lasts 15–20 years. No replacement in the 10-year window. Maybe a $300 patch repair if a BBQ burns a spot.

10-year replacement budget:

  • Sod: $1,500 to $3,000
  • Turf: $0 to $300

Total 10-year cost

Adding it all up for a 500 sq ft yard, paying for maintenance:

CostSodArtificial Turf
Installation$1,500 to $2,500$5,500 to $9,000
Water (10 yr)$1,400 to $3,350$50
Maintenance (10 yr)$15,400 to $16,100$0 to $2,900
Replacement$1,500 to $3,000$0 to $300
10-year total$19,800 to $24,950$5,550 to $12,250

Turf wins by $7,500 to $19,000 over 10 years on a small backyard. Bigger yards widen the gap.

What sod still wins on

A few honest things sod does better:

  • Cooler in summer. Real grass evaporates water and stays close to ambient temp. Turf surface temps run 30–50°F over ambient on full-sun days.
  • Smell. No way around it — turf does not smell like real grass. For some homeowners, that matters.
  • Earthworms, biology, soil health. A live lawn is part of an ecosystem. Turf is not.
  • Kids’ play feel. Soccer slide tackles on real grass beat slide tackles on turf. (Pet turf with thicker padding closes the gap.)

If those things matter to you and you’re committed to maintaining a lawn long-term, sod is a defensible choice. For most San Diego homeowners, the math doesn’t support it.

What about the SoCal Water$mart rebate?

Most San Diego water districts pay $3–$4 per square foot to convert live turf to drought-tolerant landscaping or artificial turf. For a 500 sq ft yard, that’s $1,500–$2,000 back. Apply before installation — never after.

That cuts the year-one cost gap meaningfully.
