Can a Contractor Start Work Before Getting a Permit?

In most cases, no — a contractor cannot legally start work that requires a permit before the permit is issued and posted at the job site. There are narrow exceptions for genuine emergencies, such as immediate structural hazards or water damage that must be addressed before an inspector can respond, but these are exceptions that must be documented and followed up with a permit immediately. Routine construction work must wait for the permit.

If your contractor wants to start work "and pull the permit later," that is a significant red flag. Understanding the rules around permit timing protects you from stop-work orders, fines, insurance problems, and the costly consequences of unpermitted construction.

Is it ever legal for a contractor to start work before a permit is issued?

Most jurisdictions allow emergency work to begin before a permit is issued when there is an immediate safety hazard — for example, stabilizing a structure after a storm, stopping active flooding, or making a home safe after a fire. In these cases, the contractor must typically notify the building department within 24–72 hours and apply for the permit immediately. Outside of genuine emergencies, starting work without a permit is illegal in virtually every jurisdiction.

The emergency exception has specific requirements in most jurisdictions:

• The situation must involve an immediate life-safety hazard
• The contractor must notify the building department within a defined window (often 24–72 hours)
• A permit application must be filed immediately, not weeks later
• Only emergency stabilization work can proceed — not the full project
• Inspectors may still need to view certain work stages before they are covered

Outside of genuine emergencies, any contractor who starts permitted work before the permit is in hand is violating the law. This includes roofing, electrical, plumbing, HVAC, structural modifications, additions, and most significant renovation work.

What types of work require a permit before starting?

Work that almost universally requires a permit before starting includes: new construction, additions and alterations to a structure, electrical work beyond like-for-like replacements, plumbing work beyond fixture swaps, HVAC installation and modification, roofing replacement in most jurisdictions, and any work that changes a structure's footprint, load path, or systems. The permit requirement exists to ensure an inspector can review the work at required stages before it is covered up.

Common projects that require permits:

• New construction: Any new building requires permits before the first shovel hits the ground.
• Additions: Room additions, garage conversions, ADU construction, and sunroom additions require permits before framing.
• Electrical work:New circuits, panel upgrades, new wiring — permits must be pulled before work begins, not after.
• Plumbing:Pipe relocation, water heater installation, bathroom additions — all require permits before the work is done.
• HVAC: New system installation, equipment replacement in many jurisdictions, ductwork modifications.
• Roofing: Full roof replacements require permits in most jurisdictions. Some allow re-roofing on like-for-like materials without a permit, but this varies.
• Structural modifications:Removing load-bearing walls, adding beams, altering the structure in any way requires a permit and often an engineer's approval.
• Fences and decks: Decks over a certain height and fences over a certain height require permits in most jurisdictions.

Work that typically does not require a permit includes cosmetic work (painting, flooring, cabinet replacement), like-for-like fixture replacements (same size window, same toilet), and minor repairs that do not change any structural or mechanical systems.

What happens if a contractor starts work without a permit?

If work begins without a required permit, the building department can issue a stop-work order, which immediately halts all construction. The homeowner and contractor can face fines, which in many jurisdictions are double or triple the original permit fee plus investigation costs. In serious cases, the work may need to be demolished so inspectors can verify compliance, and the contractor can face licensing board action including suspension.

The consequences escalate based on how far the work progressed and how the situation is handled:

• Stop-work order: A building inspector or code enforcement officer can issue a stop-work order that immediately halts all activity on the job site. Violating a stop-work order is a criminal offense in most jurisdictions and can result in arrest.
• Fines:Most jurisdictions charge double or triple the standard permit fee when unpermitted work is discovered. Some charge flat fines per day of non-compliance. For significant projects, total fines can reach $5,000–$20,000 or more.
• Required demolition: If work is already closed up (walls finished, insulation in place), the building department can require that work be opened so inspectors can view it. The cost of demo and reconstruction falls on the homeowner.
• Contractor license action: A licensed contractor who starts work without required permits has violated their licensing agreement. The state licensing board can suspend or revoke their license, issue fines, and require restitution to homeowners.
• Insurance implications:Work done without a permit may not be covered under homeowner's insurance if a related claim is filed. Insurers can deny claims tied to unpermitted construction.
• Resale impact: Unpermitted work must be disclosed to buyers in most states. It complicates closings, can reduce the sale price, and can cause deals to fall apart entirely.

What is a stop-work order and how does it affect your project?

A stop-work order is an official notice from the building department or code enforcement that all work on a project must immediately cease. It can be triggered by unpermitted work, work that does not match the approved permit scope, a safety violation, or a neighbor complaint. Once issued, no work can legally proceed until the violation is resolved and the order is lifted by the issuing authority.

Stop-work orders have serious practical consequences:

• Immediate halt:All work stops the moment the order is posted, regardless of where the project stands. Half-framed walls, open electrical rough-in, exposed roofing — everything freezes.
• Cost accumulation: While work is stopped, a construction crew may still be on payroll, materials may be at risk of weather damage, and temporary measures to protect the open structure add cost.
• Resolution requirements: To lift the stop-work order, the homeowner or contractor must typically appear before the building department, pay any applicable fines, and in some cases demonstrate that a licensed contractor will now handle the work.
• Project delays: Even after the order is lifted, the project may need to restart the permit process, which can add weeks or months to the schedule.

How should you protect yourself from unpermitted contractor work?

Before signing any contract for work that requires a permit, require in writing that the contractor will pull all necessary permits before work begins, and that no work will start until permits are in hand and posted at the job site. Include a contract clause making payment contingent on permit compliance. Verify the permit yourself in the building department database before the first crew member arrives.

Practical steps to protect yourself:

1. Get it in writing: Your contract should explicitly state that the contractor is responsible for obtaining all required permits before work begins. If the contractor balks at this language, that is a red flag.
2. Verify the permit before work starts:Use your local building department's online permit search to confirm the permit was issued before the crew shows up. Do not take the contractor's word for it.
3. Confirm the permit is posted: Most jurisdictions require the permit card to be visibly posted at the job site. Check that it is there and that the scope matches your project.
4. Track inspection milestones: Ask the contractor what inspections are required and when they are scheduled. Verify with the building department that inspections are being completed.
5. Verify the contractor's license first:A licensed contractor has far more to lose by pulling permits improperly than an unlicensed one. Before any contract is signed, check the contractor's license status at CheckLicensed.com — it takes seconds and costs $0.99. A license in good standing means the contractor is accountable to a state board and has professional reasons to comply with permit laws.
