What Happens If You Remodel Without a Permit in LA?

The three real consequences, in order of frequency

1. Resale gets blocked

This is what bites homeowners most often. When you sell the house:

• The buyer’s inspection checks for unpermitted work — comparing visible construction to LADBS permit records.
• The buyer’s lender requires the work to be either retroactively permitted or removed before closing.
• Retroactive permitting under LAMC §91.107.5.1 charges 2× the original fee.
• Code-upgrade corrections at current code (not original-construction code) add real cost — a 2010 kitchen with no GFCIs may need full electrical rewiring to pass retroactive inspection.

Average retroactive permitting cost for a previously unpermitted kitchen remodel: $4,000–$8,000 once corrections are factored in. Compare to the $1,500 the original permit would have cost.

2. Inspector visits during the project

Even before resale, LADBS investigations get triggered by:

• Neighbor complaints — construction noise, dust, or perceived setback violations are the most common triggers
• Contractors with grudges — disputes with contractors sometimes result in tips to LADBS
• Utility flags — LADWP or SoCalGas can flag installations that don’t match permit records

The Code Violation Inspection Fee is $356 per discovered violation under LAMC §98.0421, charged on top of whatever permit fees you’d have owed anyway.

3. Insurance denial

Rare but financially devastating. If unpermitted electrical work causes a fire, or unpermitted plumbing floods the house, the insurance adjuster will check permit records and can deny the claim citing unpermitted alteration. Insurance company lawyers do exactly this in litigated claims.

How retroactive permitting actually works

1. You (or a buyer’s agent during a sale) discover the unpermitted work
2. You hire an architect or licensed contractor to prepare as-built drawings
3. The contractor pulls a retroactive permit; LADBS charges 2× the original fee schedule
4. Inspector visits, checks the as-built against current code
5. Any code violations need correcting at current standards (GFCI outlets, AFCI protection, energy compliance, structural)
6. Once corrections pass, permit is signed off and recorded

Typical retroactive permitting timeline: 2–4 months. Cost: 3–5× what doing it right originally would have cost, between the doubled fees and the code-upgrade corrections.

What if the work was done before you bought the house?

If a previous owner did unpermitted work and you only discovered it now, you’re still the responsible party for fixing it before resale. The seller’s disclosure should have flagged it; if it didn’t, you may have legal recourse against the seller. But LADBS doesn’t care who did the work — they care that the work is now on the title you hold.

How to avoid the trap

Pull the permit upfront. The cost of doing it right the first time is always lower than retroactive permitting + the $356 violation fee + code-upgrade corrections. Specifically:

• Kitchen remodel: $1,200–$2,500 upfront vs. $4,000–$8,000 retroactively (see kitchen permit guide)
• Bathroom remodel: $800–$1,800 upfront vs. $2,500–$5,000 retroactively (see bathroom permit guide)
• Water heater replacement: $80–$120 upfront vs. $400–$700 retroactively (see water heater permit guide)
• ADU: $4,000–$15,000 upfront vs. $20,000+ retroactively if corrections are extensive (see ADU permit cost guide)

Frequently asked questions

How does LADBS find unpermitted work?

Three main triggers: pre-sale buyer inspections, neighbor complaints, and Title 24 mismatches during utility reviews. Inspectors don’t actively patrol — but anyone with a grudge or a financial reason to flag the work can trigger an investigation.

Can I just leave unpermitted work alone if I don’t plan to sell?

You can — until you do. Most unpermitted work surfaces at resale, when buyers’ lenders flag it. By then you’re paying 2× retroactive fees plus any code corrections that have piled up since.

What is the Code Violation Inspection Fee?

Under LAMC §98.0421, $356 per discovered violation. This is on top of the retroactive permit fees. Charged whenever LADBS investigates and finds unpermitted work.

Does my insurance know if work is unpermitted?

Generally no — until you file a claim. If unpermitted electrical or plumbing causes a fire or flood, the insurance adjuster will check permit records and can deny the claim citing unpermitted alteration.

Can I get a permit retroactively for old work?

Yes, but it’s expensive. Retroactive permitting under LAMC §91.107.5.1 charges 2× the original fee. Code corrections discovered during the after-the-fact inspection are required at current code, not original-build-era code.
