Avg. Lot
Based on a typical 5,500-square-foot lot in the Seattle metro area.
The biggest factor in lawn care cost is lot size — and most homeowners guess wrong. The average Seattle lot is 5,500 square feet, but your actual grass area is 30–50% less (after subtracting the house footprint, driveway, and hardscape). Use LotSite to measure the real number.
With your exact lawn measurements, you can buy the right amount of fertilizer, seed, and weed killer — no more overspending at the hardware store. For a 5,500-square-foot Seattle lot, DIY lawn care typically costs $400–$800 per year versus $1,400–$2,900 for full service.
A popular middle ground: DIY the mowing and fertilizing, then hire a pro once a year for aeration and overseeding. This approach can save 40–60% while still giving your Perennial Ryegrass lawn the specialized care it needs in Zone 8b.
