What Building Permits Cover

Building permits are required for most significant construction, renovation, and structural work. Common permit requirements:

Usually require permits:

  • Structural changes: walls added or removed, beams, load-bearing work
  • Additions and accessory dwelling units
  • Electrical work beyond simple fixture replacement
  • Plumbing beyond simple fixture replacement
  • HVAC system installation or replacement
  • Roofing (in most jurisdictions)
  • Decks, patios, and fences above certain heights
  • Pools and spas
  • Any work that changes the footprint or living space of the home

Usually don't require permits (varies by jurisdiction):

  • Painting and flooring
  • Cabinet and countertop replacement (not moving them)
  • Simple fixture replacement (faucets, light fixtures)
  • Minor cosmetic work

Always verify with your local building department: Permit requirements vary significantly by city and county. What requires a permit in one jurisdiction may not in another.

Why Your Contractor Might Skip Permits (and Why That's Your Problem)

Contractors skip permits for several reasons, all of which ultimately harm you:

To save time: Permit processing can take days to weeks. Inspections require scheduling and pausing work. Contractors on tight schedules skip permits to move faster.

To hide substandard work: Inspections catch code violations. Work that would fail inspection gets covered up without a permit.

To avoid code compliance: Some work would require expensive upgrades to comply with current code — the contractor skips the permit to avoid doing the work correctly.

The homeowner's consequences:

  • Legal liability for the unpermitted work: If someone is injured in or around unpermitted work, you may be liable as the property owner
  • Insurance coverage gaps: Homeowner's insurance may not cover losses in areas of unpermitted work
  • Sale complications: Unpermitted work discovered in the buyer's inspection can crater a sale or require expensive remediation
  • Mandatory demolition orders: Building departments can order unpermitted structures demolished or work undone
  • Lender problems: Refinancing or home equity loans may be denied if appraisers note unpermitted space

Discovering Unpermitted Work After the Fact

If you discover that your contractor did not pull required permits:

Step 1 — Verify by checking permit records: Your city or county's building department maintains permit records. Request permit history for your property. Many jurisdictions have online portals (search '[city name] building permit lookup'). If no permit appears for your project, confirm the contractor's claim that they pulled one.

Step 2 — Demand documentation from the contractor: Ask for the permit number and inspection records. A licensed contractor who pulled permits can provide these immediately.

Step 3 — Assess the work's compliance with code: Contact your building department and explain the situation. Ask whether you can retroactively permit the work. 'As-built' permits are sometimes available for completed work, requiring an inspection.

Step 4 — Get an independent inspection: A licensed contractor or inspector can assess whether the unpermitted work meets code standards — and what would need to change to bring it into compliance.

Step 5 — Pursue the contractor: The failure to pull required permits is typically a breach of contract and a licensing violation. This is grounds for a claim against their license bond and a complaint to the licensing board.

Retroactive Permitting: The Legalization Path

In many jurisdictions, you can retroactively permit completed work — the building department issues an 'as-built' or 'after-the-fact' permit:

How it works: You apply for a permit for work already done. An inspector comes out and evaluates whether the work meets current code. If it passes, the permit is issued. If it doesn't pass, you're given a list of corrections required to bring it to code.

Costs: Permit fees (same as for advance permits), plus any corrections required by the inspector, plus potential fines for the unpermitted work (varies by jurisdiction).

Your legal exposure during the period: If someone is injured in connection with uninspected, potentially code-violating work, you have exposure regardless of whether you knew about the permit issue.

Responsibility: The contractor should pay for retroactive permitting and all corrections required to bring their work to code. Put this demand in writing and include it in your dispute claim.

When the Building Department Orders Demolition

In the worst cases, building departments have the authority to order unpermitted structures demolished:

When this happens: When work is egregiously non-compliant with code, when retroactive permitting isn't possible, or when the work poses an immediate safety hazard.

Example: An unpermitted room addition that lacks proper egress windows, has inadequate electrical, and wasn't built on a proper foundation may be ordered demolished as non-correctable.

Your response:

  1. Request a hearing with the building department — you have the right to contest the order
  2. Get a structural engineer or code compliance specialist to evaluate whether the work can be brought to code
  3. Consult a construction attorney — demolition orders can sometimes be challenged
  4. Pursue the contractor for the full cost of demolition and reconstruction

The contractor's liability: A contractor who performed work that leads to a demolition order is liable for the full cost of demolition and reconstruction. This is a strong legal claim — document everything and consult an attorney immediately.

Frequently Asked Questions

Quick answers to the most common questions on this topic.

Whose responsibility is it to pull the building permit — mine or the contractor's?

+

Generally the contractor's, though you can also pull permits as the owner-builder. Most home improvement contracts specify that the contractor is responsible for all required permits. If the contract is silent, the party doing the work is typically responsible for ensuring it's permitted.

Can I sell my house with unpermitted work?

+

Technically yes, but you may be required to disclose it. Buyers' inspections often reveal unpermitted additions. Lenders may not finance homes with significant unpermitted work. Retroactively permitting or disclosing and adjusting the sale price are the typical paths for sellers.

What if my contractor told me the project didn't need a permit?

+

You should have verified this independently with your local building department before work began. But misrepresentation about permit requirements is breach of contract. Document what the contractor told you (texts, emails) and pursue compensation for any costs you incur from the unpermitted work.

Can I be fined for unpermitted work I didn't know about?

+

Yes. As the property owner, you're responsible for work done on your property. Fines for unpermitted work are typically assessed against the property owner, not just the contractor. You can then seek reimbursement from the contractor.

Does homeowner's insurance cover damage from unpermitted work?

+

Policies vary. Many exclude coverage for damage from unpermitted work, especially if the lack of permit contributed to the damage. This is another reason why permitting matters — your insurance coverage may depend on it.
