FAQ: Budgeting for Permits and Utility Hookups
How much should you budget for permits and utility hookups?
Plan to spend $5,000 to $30,000+ for utility hookups and $500 to $2,000+ for permits. Exact costs depend on location, distance to services, utility types, and project complexity.

Costs vary by location, distance to existing lines, number of utilities, soil and terrain conditions, and permit requirements. Urban areas often have higher fees, while rural areas face higher hookup costs due to longer utility runs.

The farther your property is from existing water, sewer, or power lines, the higher the cost. Extending utilities requires trenching, piping, and sometimes new infrastructure.

What are impact fees in construction projects?
Impact fees are local charges to fund infrastructure expansion in growing areas. They can add thousands of dollars to hookup costs and should be included in your budget.
How can you get the most accurate estimate for permits and hookups?
Contact your local municipality for permit fees and reach out to utility providers for connection quotes. This ensures your budget reflects site-specific conditions.
What additional costs should you plan for besides permits and hookups?
Expect extra expenses for grading, trenching, and inspections. These site-prep and compliance costs can significantly increase the total budget.
