We are buying a house in LA. Is a chimney inspection necessary?

It is the applicable standard at property transfer under NFPA 211, and in this city it carries extra weight given the seismic history. Your general home inspection will not have examined the inside of the flue — that is outside its scope, not an oversight.

Can you tell the liner is damaged by looking in the firebox?

You can see the very bottom of the flue and essentially nothing else. Cracking and joint separation higher up are not visible from below, which is the specific gap a camera survey fills and the reason inspection is a distinct service.

Should we inspect after every earthquake?

After shaking significant enough to move objects in the house, yes. Magnitude headlines matter less than what actually happened at your address. Seismic liner damage is invisible from the room, so there is no symptom to wait for.

What if the inspection finds nothing?

Then an unknown has become a documented known, which has real value both for your own planning and at the point of sale. An inspection that always produces a repair quote is not functioning as an inspection.

Chimney Inspection in Los Angeles, CA

Los Angeles has an unusually large number of chimneys with an unknown internal history. The 1994 earthquake is most of the reason.

What is different about chimney inspection in Los Angeles

The 1994 Northridge earthquake cracked flue liners across Los Angeles, and repairs frequently rebuilt the visible stack without anyone assessing the clay tile liner inside.
LA's property market turns over rapidly, so most homes have changed hands several times since 1994 with no record of the flue ever being surveyed.
The city's very large pre-1960 masonry stock means clay tile liners here are commonly sixty to a hundred years old, well into the range where joint separation is expected.

The Northridge Gap

In January 1994 the Northridge earthquake damaged chimneys across the Los Angeles region. Where stacks cracked or partially collapsed above the roofline, they were generally rebuilt — visible damage, visible repair.

What frequently did not happen was anyone assessing the flue liner inside. Seismic movement separates clay tile sections at their mortar joints and cracks the tiles, and none of that leaves a trace visible from the room. Three decades and several property transfers later, that internal condition is simply unknown in a great many LA houses.

Why a Home Inspection Does Not Cover It

This catches people out at purchase, and it is worth being explicit. A general home inspection is a broad survey, and flue interiors are outside its scope — the equipment and the access are not part of that job.

An inspector can reasonably report that the fireplace exists and appears sound. That is a different statement from the liner forty feet up being intact. NFPA 211 treats property transfer as a Level 2 trigger for exactly this reason, and in a city with LA's seismic history the reasoning is stronger than average.

What the Camera Is Looking For

Cracked or spalled clay tiles. Joint separation between liner sections. Deterioration in the smoke chamber. Debris and nesting material. Evidence of a previous flue fire. Whether the flue is correctly sized for whatever is connected to it.

If the survey finds liner damage, the work that follows is relining rather than repair, and it is a considerably larger job than a cleaning. Which is precisely why establishing the condition before committing to anything is the sensible order.

Chimney Inspection in Los Angeles — common questions

It does, because a lot of it was never assessed. Repairs commonly addressed the stack above the roofline, which was the visible damage. Clay tile liners separate at their joints without any external sign, so where nobody put a camera up the flue, the question is still open three decades later.
