The answer to the cost of an irrigation system is that it can vary widely depending on several factors. The typical range for a basic residential irrigation system can be anywhere from $2,000 to $5,000 or more, but the final cost will depend on the size of your lawn, the complexity of the system, the type of sprinklers used, and whether you need to install new plumbing or electrical work.
Generally, the larger your property and the more zones or valves required, the higher the overall cost will be. High-end sprinkler heads, smart controllers, and other advanced features can also increase the price. It's important to get quotes from local irrigation specialists to get an accurate estimate for your specific needs and location.
