What you actually need before pulling a permit
- Local business license / BTRC. Annual, ~$50–$500. Required by most cities even if your state license is current.
- Local contractor registration. Some metros (NYC, Indianapolis, Chicago, Denver, DC) layer their own contractor license on top of state credentials.
- Workers' compensation certificate showing the AHJ as additional certificate holder.
- General liability certificate with the jurisdiction's required minimums (often $1M / $2M).
- Plans signed/sealed by a licensed design professional for any structural, MEP, or use-change work above a small threshold.
- Owner authorization if you're pulling on behalf of the property owner.
- Energy code, accessibility, and zoning sign-offs for new commercial work.
Working in unfamiliar jurisdictions
Three rules that save weeks of pain when you're new to a market:
- Pre-app meeting. Most building departments offer a free 30-minute meeting with a plans examiner. Bring schematic drawings. They'll flag local amendments and special inspection requirements before you spend money on full CDs.
- Find a local expediter for your first 2–3 projects. $500–$3,000 well spent. They know what flags the reviewer, what triggers a corrections cycle, and the unwritten formatting rules.
- Read the local amendments to the IBC/IRC. Every city amends the model code. NYC, Chicago, Miami-Dade, LA, and Seattle have especially aggressive amendments. Code-of-record vs. enforcement edition often differs.
Frequently asked questions
Do I need a city license if I have a state contractor license?+
Almost always, yes. A state contractor license authorizes you to perform the work; a city/county business license authorizes you to operate as a business within that jurisdiction. They're separate. Many cities also require a contractor registration in addition to the business license.
What's an AHJ?+
Authority Having Jurisdiction. The local code official who reviews plans, issues permits, performs inspections, and signs off the certificate of occupancy. Always confirm requirements directly with the AHJ — interpretation of model codes (IBC, IRC, NEC) varies and amendments are common.
Can I pull permits in someone else's name?+
No. The permit must be pulled by the licensed contractor performing the work, or by the homeowner if owner-builder rules allow. Pulling permits for an unlicensed contractor is illegal in most states and exposes you to civil and criminal liability.
How long do permits take?+
Trade permits (electrical, plumbing, mechanical) in most metros are over-the-counter or same-day. Residential building permits run 1–4 weeks. Commercial permits run 4–12 weeks for first review, longer with revisions. Many cities offer express/expedited review for an additional fee.
What happens if I work without a permit?+
Stop-work orders, double or triple permit fees, fines, mandatory uncovering of completed work for inspection, voided insurance coverage, voided manufacturer warranties, and personal liability for any future defect. Resale of the property triggers disclosure of unpermitted work, which routinely kills deals.
