San Francisco, California | Fire date: Tuesday, February 3, 2026
Most restaurant fires we hear about come with a lot of guessing. This one doesn't. The fire department told reporters where it started, and it's right in the part of the system we get paid to clean.
What happened at Mel's
Early Tuesday morning, February 3, 2026, fire broke out at Mel's Drive-In, 2165 Lombard Street, in San Francisco's Marina District. SFGATE reported the call came in just after 4 a.m. Two members of the cleaning staff were working outside when they saw fire on the roof and called the general manager.
Here's the part that matters to us. According to SFGATE, once San Francisco Fire Department crews were on scene they determined a grease fire had ignited in a vent above the kitchen. ABC7 and KTVU both reported SFFD saying the fire started in the flue area of the kitchen. KTVU reported it spread from the hood above the stove and into the attic.
SFFD Lt. Mariano Elias put it in plain words for SFGATE:
That's the whole job in one sentence.
To make sure no fire was hiding in the ceiling, crews cut a hole in the roof. SFGATE said the kitchen had "extensive damage." ABC7 reported much of the ceiling above the kitchen looked burned or melted away. KTVU described melted ceilings and puddles of water left behind. It was a one-alarm fire and nobody was hurt.
KTVU reported the location was closed indefinitely. The owners said they hoped to reopen in a few months and plan a grand reopening for the community.

Why this is a hood cleaner's story
Every commercial kitchen pushes grease-laden vapor up through the hood. Some of it gets caught by the filters. Some of it doesn't. That grease coats the inside of the ductwork and the exhaust fan, and it keeps building with every shift.
When it lights, it doesn't stay put. It runs up the duct. That duct goes through ceilings, attics and roofs, the places nobody can see and the fire department has to cut open to reach. That's how a kitchen fire turns into a roof fire and a months-long closure.
Look at what this cost. Not just a hood and a ceiling. A restaurant that's been part of that neighborhood since 1985 went dark, and a crew of employees lost their workplace for a while. That's the real price of grease left in a duct.
NFPA 96 and doing the whole system
NFPA 96 is the standard that covers fire protection for commercial cooking operations, including inspecting, cleaning and maintaining the grease exhaust system. How often a system needs cleaning depends on the type and volume of cooking, so go by the standard and your local fire authority. Don't go by a one-size-fits-all number.
What a real hood cleaning job looks like:
A shiny hood with a dirty duct behind it isn't a clean system. It's a liability with your sticker on it.
Be fair about it
The reporting tells us where the fire started. It doesn't tell us when that system was last cleaned, who cleaned it, or whether anybody did anything wrong. KTVU reported the cause was still under investigation. So I'm not pointing fingers at Mel's or at any contractor. I'm sharing this because it's a documented example of exactly what we warn our customers about.
If you read my earlier post on the 2009 Tadich Grill flue fire, this one belongs right next to it. Two iconic San Francisco restaurants, and in both stories the trouble was up in the flue.
Rooting for Mel's
Mel's goes back to 1947 in San Francisco, and the Lombard Street location reopened the brand in 1985. KTVU called it the longest continuously running Mel's Drive-In. I hope the owners and the crew get that grill back on soon.
Use this one with your customers. Tell them what happened, then show them what you clean.

SFFD Lt. Mariano Elias put it in plain words for SFGATE:
Lt. Mariano Elias said:What ends up happening is a lot of grease gets trapped in there, and the restaurants are supposed to clean it, but sometimes all that grease, that sticks on the inner walls of the metal piping, ignites once it gets hot enough.
That's the whole job in one sentence.

What a real hood cleaning job looks like:
- Inspect the hood, filters, ductwork and fan for grease buildup.
- Clean the complete system, hood to fan, not just the part the customer can see.
- Use trained, qualified people.
- Document what you cleaned, what you couldn't reach, and when.
- Report inaccessible or problem areas to the owner in writing so they can get them fixed.
- Follow your local fire authority's requirements.
