Site Work Categories
Clearing and Demolition
- Tree removal and stump grinding
- Brush and debris clearing
- Existing structure demolition (if applicable)
- Hazardous material removal
Typical cost: $2,000-$15,000 depending on lot condition
Grading and Earthwork
- Rough grading to establish building pad elevation
- Cut and fill operations
- Soil import or export
- Fine grading for drainage
Typical cost: $3,000-$20,000 depending on topography
Excavation
- Foundation excavation
- Utility trench excavation
- Basement excavation (if applicable)
- Rock removal (if encountered)
Typical cost: $2,000-$25,000+ (rock significantly increases cost)
Utility Connections
Water
- Water main tap and meter
- Service line from main to house
- Well drilling (rural areas)
Typical cost: $2,000-$15,000 (well drilling can exceed $15,000)
Sewer
- Sewer tap and connection
- Service line from house to main
- Septic system (rural areas)
Typical cost: $2,000-$20,000 (septic systems can exceed $15,000)
Electric
- Power company service connection
- Transformer installation (if needed)
- Underground or overhead service run
- Temporary construction power
Typical cost: $1,000-$10,000
Gas
- Gas main tap and service line
- Meter installation
Typical cost: $500-$3,000
Access and Paving
- Driveway construction
- Temporary construction access road
- Sidewalks and walkways
Typical cost: $3,000-$15,000
Stormwater and Erosion Control
- Silt fencing and erosion barriers
- Retention or detention basins
- French drains or swales
- Stormwater management compliance
Typical cost: $1,000-$10,000
Common Cost Surprises
- Rock: Unexpected rock during excavation can add $5,000-$50,000+
- Poor soil: May require soil removal and replacement or engineered fill
- High water table: Dewatering and specialized foundation systems
- Long utility runs: Remote lots with distant utility mains
- Wetlands or environmental: Mitigation requirements can be very expensive
- Impact fees: Some jurisdictions charge significant development impact fees
