Earthquake Retrofit in Los Angeles: Which Requirements Apply to Your Building

Los Angeles does not have one earthquake retrofit rule. It has several, they were written decades apart, and each one is triggered by something different: the year the building was permitted, how it is framed, how many units it has, or simply the fact that you are about to sell it.

Most owners discover which one applies to them at the worst moment, when a deadline has already passed or an inspection report has already been written. This guide exists so you can find yourself on the list first.

Find your building

Start here. Most properties in Los Angeles fall into one or more of these:

A single-family house on a raised foundation, built before about 1980

This is the cripple wall and sill plate problem: the house is simply resting on its foundation rather than bolted to it. It is the most common and most fixable vulnerability in the city, and there is a state grant program for it. Full detail in house bolting and cripple wall bracing in Los Angeles.

Any building with gas piping that is being sold, or that has permitted work over $10,000

A seismic gas shutoff valve is required, and the trigger is much broader than people expect. It catches almost every remodel, not just sales. For condominiums on a single gas line it becomes a building-level obligation. Full detail in seismic gas shutoff valves in Los Angeles.

A house with an old brick chimney

Unreinforced masonry above the roof line, usually tied to the structure by very little. The rules for putting one back after damage are far stricter than most owners assume, and masonry is rarely allowed back. Full detail in chimney retrofit and reconstruction in Los Angeles.

A wood-frame building of four or more units, permitted before 1978, with parking or open space at the ground floor

This is the mandatory soft-story ordinance, and every compliance deadline under it has now passed. If the work is not done, the building has an open code enforcement matter rather than a pending project. Full detail in soft-story retrofit for property managers and HOA boards.

A concrete building, other than a one or two family house, permitted before 13 January 1977

This is the non-ductile concrete ordinance, Division 95 of the Municipal Code. It runs on a much longer clock than the wood-frame rule: within three years of the order a California-licensed civil or structural engineer must submit a checklist, within ten years a detailed structural evaluation, and within twenty-five years the retrofit itself must be complete. Orders began going out in late 2017, so the evaluation stage is the live one for most of these buildings.

An unreinforced masonry building

Los Angeles was the first city in the country to require these to be retrofitted, under an ordinance adopted in 1981. That program is long closed. If you own a URM building that was never brought into compliance, it is an old and serious open item, not a new one.

Mandatory and voluntary are not the same conversation

Two of the items above are mandatory in the strict sense: the soft-story ordinance and the non-ductile concrete ordinance both come with an order to comply, a deadline and an enforcement path. The seismic gas valve is mandatory too, but conditionally, triggered by a sale or by permitted work.

House bolting and chimney work are different. Outside of a sale or a damage event nobody orders you to do them. They are voluntary, which in practice means they are the ones people put off, even though they are the cheapest and the ones with grant money attached.

The distinction matters because it changes what you are buying. With a mandatory item you are buying the removal of a legal exposure. With a voluntary one you are buying the difference between a house that is repairable after a quake and one that is not.

What every one of them has in common

However different the buildings are, the process is the same shape:

1. An engineered design, or a pre-approved standard plan where one exists. Los Angeles publishes standard plans for the common cases, and they are considerably faster than a custom design

2. A permit. There is no compliant version of this work without one

3. Inspections at defined stages, not just at the end

4. A paper trail: stamped plans, the permit, the signed inspection card, and the certificate of compliance where the ordinance calls for one

That last item is the one people undervalue, and it is the one that gets asked for years later, by an insurer at renewal, a lender on a refinance, a buyer's agent in escrow, or the Housing Department on a cost recovery application.

The point-of-sale layer sitting on top of all of it

Separately from the retrofit ordinances, selling a residential property in Los Angeles requires a Residential Property Report from the Department of Building and Safety, which almost everyone calls the 9A report.

The 9A does not create retrofit obligations by itself. What it does is surface them. It lists the open point-of-sale items on the property, and it is where a missing seismic gas valve, unpermitted work or an open order stops being theoretical and starts being a line in a negotiation.

If a sale is anywhere in the next year or two, pull the report early. Everything on it is cheaper to handle before a buyer is looking at it.

Money: the two programs worth knowing about

For houses: Earthquake Brace + Bolt.

A state-backed program offering a grant toward a code-compliant cripple wall and sill plate retrofit on qualifying older houses. Registration windows open periodically and are geographically targeted, so eligibility depends on your ZIP code as well as your house.

For rent-stabilized buildings: LAHD cost recovery.

An owner who completes a mandatory seismic retrofit can apply to recover part of the approved cost through a temporary monthly surcharge, spread over ten years and subject to a per-unit ceiling and to the Housing Department's approval. It is not automatic and it depends entirely on documentation kept from the start of the job.

Who is legally allowed to do this work

All of it is structural, all of it is permitted, and in California any project over $500 in combined labor and materials requires a licensed contractor.

Retrofit work also sits squarely in Class B general building territory rather than in a single trade, because a real retrofit touches concrete, framing, steel, and often plumbing and finishes on the way through. One license carrying one set of inspections is the point.

Common questions

How do I find out whether my building has an order?

Orders to comply are recorded against the property and are visible in the city's own records. If you bought the building after the order was issued, it may never have reached you personally. It still applies.

Can I do one part now and the rest later?

Often yes, and sometimes that is the right sequence. What you should not do is work in an order that makes you open the same wall or the same slab twice.

Does a retrofit lower my insurance?

Some carriers offer a discount for a documented retrofit, and the California Earthquake Authority has offered one for qualifying houses. Ask your carrier specifically, and have the permit and the final inspection card ready when you do.

What does it cost?

There is no useful answer to that in a blog post, and the sites that publish ranges are publishing numbers that will be wrong for your building. Foundation condition, access, the framing you find once you open it up, and whether a standard plan applies all move the figure substantially. We would rather look at it with you than guess in public.
