How Much Does Excavation Cost in Sacramento, CA?

Short answer

Excavation in the Sacramento region is usually priced by the cubic yard, by the hour, or by the day. Typical residential excavation runs $50 to $150 per cubic yard of material removed; a machine plus operator runs $120 to $300 per hour; day rates run roughly $800 to $3,000 depending on machine size. Many residential digs — footings, a utility trench run, a small basement or crawl space, a pool cavity, a pad cut — land between $1,500 and $10,000, while larger or deeper excavation with rock, water, or shoring can run well past that. Depth, soil conditions, and how far the spoils have to travel are the numbers that move most. These are Sacramento-region planning ranges for 2026; pricing the actual site is the only way to a firm number.

Excavation cost by pricing method

Contractors quote excavation in whichever unit fits the job. National figures from HomeGuide and HomeAdvisor put excavation around $50 to $200 per cubic yard, $40 to $150 per hour for smaller equipment, and $1,500 to $6,000 for many residential projects — consistent with local pricing once Sacramento soil, water table, and haul realities are factored in.

What goes into an excavation number

The line items that build up an excavation price:

• Equipment and operator — mini excavator, standard excavator, skid steer, or backhoe; day rates for machine plus operator commonly run $800 to $3,000 by size
• Mobilization — trucking equipment in and out is a fixed cost that weighs heaviest on small jobs
• Spoils haul-off and disposal — excavated soil is heavy; haul distance and tipping fees at the disposal or clean-fill site are a distinct cost
• Soil and rock conditions — clay, hardpan, cobbles, or rock slow digging and can require heavier equipment or breaking
• Depth and shoring — under OSHA rules, excavations five feet or deeper generally need a protective system (sloping, benching, shoring, or a trench box), which adds cost
• Dewatering — near the American and Sacramento Rivers the water table can be high; pumping and managing groundwater adds time and equipment
• Utility locating — USA North 811 markout is required before digging; private locates and hand-digging around marked lines add labor
• Access — narrow side yards, gates, slopes, and overhead lines can force a smaller machine or hand work

Local cost factors in the Sacramento region

Sacramento-area geology changes the dig. In the valley, expansive clay and cemented hardpan are common — both are slower to excavate than loose sandy soil, and hardpan sometimes needs a breaker. Near the American and Sacramento Rivers, and in older parts of the basin, cobbles and a seasonally high water table show up; a high water table can require dewatering, which adds pumps, time, and disposal of the water. In the foothills, decomposed granite and rock are the norm and can meaningfully slow a dig. Excavated spoils typically haul to a clean-fill site or a regional facility such as Kiefer Landfill, and because loaded dirt is heavy, haul distance is a genuine cost driver. Before any dig, USA North 811 utility locating is required by law — hitting an unmarked line is dangerous and expensive. Permit requirements and fees for excavation vary by jurisdiction, so treat them as "varies by jurisdiction" until the contractor confirms with the local building department; deeper excavation near structures may also require a soils/geotechnical report.

What a complete excavation quote should include

• Excavation footprint and depth, in writing
• Estimated cubic yards and whether spoils stay on-site or haul off
• Haul-off and disposal cost, itemized separately from digging
• Assumptions about soil, rock, and groundwater — and what happens if conditions differ
• Shoring, sloping, or trench protection where depth requires it
• USA North 811 locating and hand-dig allowances around utilities
• Who pulls any permit and orders a soils report if needed
• Access plan and site protection

How to estimate excavation volume

Because excavation is priced on volume, a rough estimate helps you sanity-check a quote. A cubic yard is 27 cubic feet — think of a hole three feet wide, three feet long, and three feet deep. To ballpark a dig, multiply length by width by depth in feet and divide by 27; a 20-by-20-foot area dug two feet deep is about 30 cubic yards. Two things push the real number above that math: swell, where soil expands roughly 15 to 30 percent once it's dug loose, so hauled volume exceeds in-ground volume; and over-excavation, where the crew digs past the neat line for working room, shoring, or to remove unsuitable soil. Share your rough dimensions and we can translate them into truck loads and disposal weight.

Frequently asked questions

• How is excavation priced? By the cubic yard removed ($50–$150 typical), by the hour for machine plus operator ($120–$300/hr), or by the day ($800–$3,000 by machine size). Trenching is often priced per linear foot ($8–$25).
• What drives excavation cost up? Rock, hardpan, and cobbles; a high water table needing dewatering; depth that triggers shoring under OSHA rules; heavy spoils haul-off; tight access; and unmarked utilities.
• Do I need a permit to excavate? Often, especially for work tied to a structure, foundation, retaining wall, utility connection, or the public right-of-way. USA North 811 utility locating is required by law before any dig.
• Is haul-off included in an excavation quote? Not always. Heavy spoils and haul distance make disposal a separate line. If soil can stay on-site as fill, you save; if it must leave, confirm that cost is in the number.
• How do I get an exact excavation number? Send the address, photos of the area and access path, and the depth and footprint you need. Volume, depth, soil, water, and access all drive the price.
