How Much Does a Building Permit Cost?

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.

Which Cities Have the Most Expensive Permits?

Los Angeles: $8,000–12,000 base + school impact fees ($4.08/sqft). All-in for 2,000 sqft: $25,000+. Timeline: 12–20 weeks.

NYC: DOB fees + mandatory expediter ($3,000–8,000). Total: $15,000–$30,000+. Timeline: 8–24 weeks.

Denver: Moderate fees ($3,000–6,000) but 8–14 week backlogs. Carrying costs on a $400K loan during delays can add $10,000+.

Houston: $1,500–4,000 with 4–8 week turnaround. No zoning code simplifies some aspects, but deed restrictions and flood requirements still apply.


How Can I Reduce Permit Costs?

  1. Know requirements before you apply — incomplete applications trigger resubmission fees. Check your zoning first.
  2. Use pre-approved plans — saves $1,000–3,000 in review fees
  3. Check for fee waivers — California waives most ADU impact fees
  4. Get your Buildability Report first — a $29 report tells you what’s allowed before spending $3,500 on a consultant
