The cost of asphalt paving services in California can vary based on factors such as project size, location, site conditions, and the amount of surface preparation required. On average, asphalt driveway installation typically costs between $3 and $7 per square foot, while parking lot paving generally ranges from $2 to $5 per square foot. For resurfacing or overlay projects, property owners can expect to pay approximately $1 to $3 per square foot. Several factors influence the final cost, including the condition of the existing surface, the required asphalt thickness, labor expenses, material costs, drainage requirements, and any necessary grading or excavation work. Larger paving projects often benefit from economies of scale, resulting in a lower overall cost per square foot compared to smaller jobs. Proper installation and quality materials can help ensure long-lasting performance and reduce future maintenance expenses.
