How Much Does a Building Permit Cost?
Building permit costs range from $400 to $50,000+ depending on project type, location, and valuation. Here’s what to expect and how to reduce your costs.

Permit costs range from $400–$5,000+ for residential projects and $5,000–$50,000+ for commercial, depending on project scope, location, and construction valuation. Most jurisdictions charge 1–2% of total construction value. But the biggest cost isn’t the permit itself — it’s the consultant fees ($2,000–$5,000) and time (4–16 weeks) to navigate the process.

What Determines Building Permit Cost?
Most cities use a valuation-based fee schedule — typically 1–2% of estimated construction cost. A $200,000 renovation generates a $2,000–4,000 permit fee. A $2M commercial build could hit $20,000–40,000. Beyond the base fee, expect plan review fees (65–80% of permit fee), inspection fees, and impact fees that can double the total.
