Fake grass, also known as artificial lawn or turf, can provide the look of real grass but without the care needed to maintain it. If you enjoy DIY projects, then basic materials will cost an average of $5.00 a square foot. If you opt to rent a sod cutter and a compactor, the price will rise by roughly $1.50 per square foot. For professionally installed grass, expect a cost of $10 plus per square foot. A smaller project will usually cost more per square foot than a larger project.
