Buying a Soft-Story Building in LA: Retrofit Costs, Compliance & Upside

By Glen Scher and Filip Niculete| LAAA Team at Marcus & Millichap | April 7, 2026

Los Angeles' mandatory seismic retrofit program (Ordinance 183893) has identified approximately 13,500 wood-frame soft-story buildings that require structural reinforcement. For buyers, this creates a split market: compliant buildings trade at full value, while non-compliant buildings trade at discounts of 10-30% depending on estimated retrofit costs and deadline proximity. If you understand the retrofit process, costs, and timeline, non-compliant soft-story buildings represent one of the clearest value-add opportunities in the LA apartment market.

What Makes a Building Soft-Story?

A soft-story building has a structurally weak ground floor, typically caused by open parking areas or large commercial spaces that lack adequate lateral bracing. In an earthquake, the ground floor can collapse while upper floors remain intact, a failure mode called "pancaking."

Most soft-story apartment buildings in LA share these characteristics:

  • Wood-frame construction
  • Built before 1978 (overlapping with RSO)
  • Ground-floor tuck-under parking with apartments above
  • 2+ stories with 3+ units
  • Located in the City of Los Angeles

LADBS (Los Angeles Department of Building and Safety) maintains the public inventory. Check whether your target building is on the list before making an offer.

The Compliance Timeline

Priority TierBuilding TypeStatus
Priority 116+ units or 3+ storiesDeadlines passed or imminent
Priority 2All remaining soft-storyMust comply by April 2028

Buildings that miss deadlines face escalating penalties, potential vacate orders, and insurance cancellation. The deadline creates real urgency even if city enforcement is inconsistent.

Retrofit Costs: What to Budget

Retrofit costs depend on building size, configuration, and site conditions. Get a structural engineering estimate for your specific building, but use these benchmarks for initial underwriting:

Building SizeCost Per UnitTotal Range
4-8 units$5,000-$15,000$20,000-$120,000
9-20 units$10,000-$25,000$90,000-$500,000
21+ units$15,000-$40,000$315,000+

What drives cost variation:

  • Number of parking spaces to reinforce — More open bays = more steel moment frames needed
  • Foundation condition — Some retrofits require foundation upgrades, which add 30-50% to the cost
  • Hillside or slope — Complicated access and non-standard configurations increase engineering and construction costs
  • Existing modifications — Unpermitted alterations to the ground floor can complicate engineering

Can You Pass Retrofit Costs to Tenants?

For RSO buildings, LAHD allows landlords to pass through 50% of seismic retrofit costs to tenants over 10 years through a capital improvement surcharge. The surcharge requires LAHD approval and is limited to a percentage of base rent. This does not recover the full cost, but it reduces the net impact.

How to Underwrite a Non-Compliant Soft-Story Building

The acquisition formula is straightforward:

  1. Establish compliant value — What would the building be worth fully retrofitted? Use cap rate and price-per-unit comps from compliant sales in the same submarket.
  2. Estimate retrofit cost — Get a structural engineering estimate or use per-unit benchmarks. Add 10-15% contingency for unknowns.
  3. Add execution risk premium — Construction delays, permit delays, tenant disruption, and the possibility of cost overruns. Budget 5-10% of retrofit cost as risk premium.
  4. Calculate your offer price — Compliant value minus retrofit cost minus risk premium = your target acquisition price.

Example: A 12-unit soft-story building in Van Nuys. Compliant comps suggest $300,000/unit = $3,600,000 compliant value. Engineering estimate: $180,000 retrofit ($15,000/unit). Risk premium: $20,000. Your target price: $3,400,000 ($283,000/unit). If the seller is asking $3,600,000, you have a clear basis for negotiating down.

Insurance: The Hidden Force Behind Soft-Story Deals

Insurance is the real driver behind soft-story urgency, not city enforcement. Here is what is happening:

  • Insurers are declining to renew policies on non-compliant soft-story buildings
  • When coverage is available, premiums are 2-5x higher than compliant buildings
  • Some carriers require proof of retrofit progress before issuing any coverage
  • Without insurance, lenders will not fund loans or will force-place expensive coverage

For buyers, this means:

  • Verify insurance availability before going under contract. Get a quote from your insurance broker during DD, not after.
  • Budget higher insurance costs for the period between acquisition and retrofit completion
  • If a non-compliant building cannot be insured at any reasonable cost, the deal may not be financeable

Tenant Impact

Retrofits are noisy and disruptive but typically do not require tenant relocation. Most work is done at the ground floor (parking level). Tenants may lose parking access temporarily. If units are directly affected (rare), temporary relocation may be required.

Value Creation Strategy

The smartest soft-story acquisition play combines retrofit with other value-add improvements:

  1. Acquire at a soft-story discount (10-30% below compliant comps)
  2. Complete retrofit (immediately removes the discount)
  3. Renovate vacant units during retrofit (since construction is already underway)
  4. Capture rent resets on turnover (combine RSO vacancy decontrol with upgraded units)
  5. Refinance at compliant value (pull out retrofit capital through a refi, effectively recycling your investment)

This strategy works because the retrofit discount is a known, quantifiable cost, not speculative upside. You are buying a dollar for 70-90 cents and adding 30-10 cents of cost to close the gap. The return on the retrofit investment itself is 2-3x in most cases.

Red Flags in Soft-Story Acquisitions

  • No engineering estimate — If the seller has not obtained one, get your own during DD. Without a real estimate, you are guessing at retrofit cost.
  • Active violations — LADBS violations beyond the soft-story retrofit (fire safety, electrical, plumbing) compound your compliance burden.
  • Foundation issues — Some older buildings have foundation problems independent of the soft-story condition. A foundation upgrade on top of a seismic retrofit can double the total cost.
  • Insurance cancellation notice — If the current owner's insurance has been canceled or is non-renewable, your options are limited and expensive.
  • Priority 1 deadline missed — If the building is Priority 1 and the deadline has passed, penalties are accumulating. Factor in back penalties when negotiating.

Frequently Asked Questions

Is buying a non-compliant soft-story building a good investment?

It can be excellent if you underwrite the retrofit cost accurately, verify insurance availability, and budget realistically for timeline and construction contingencies. The discount on non-compliant buildings compensates for the retrofit cost and then some. The risk is in the unknowns: foundation condition, permit delays, and insurance availability.

How much discount should I expect on a non-compliant soft-story building?

Typically 10-30% below compliant comparable sales. The discount depends on estimated retrofit cost, deadline proximity, insurance status, and buyer pool depth. Buildings close to their deadline with no engineering plan trade at deeper discounts because urgency is highest and uncertainty is greatest.

Can I get a loan on a non-compliant soft-story building?

Yes, but options are limited. Most banks will lend on non-compliant soft-story buildings if the borrower commits to completing the retrofit within a specified timeframe (usually 12-18 months). Agency lenders are more restrictive. You may need to hold back retrofit funds in escrow or provide a letter of intent from a structural engineer. Some lenders will not fund at all without proof of insurance, which is the real bottleneck.

How long does a soft-story retrofit take?

4-9 months from engineering to final inspection. The permit phase (6-12 weeks) is typically the longest. Construction itself is 6-16 weeks for most buildings. Plan for the longer end of the range in your timeline to avoid being caught by insurance or compliance deadlines.

Do tenants have to move out during the retrofit?

Usually not. Most retrofits involve steel frame installation at the ground floor parking level. Tenants experience noise and temporary parking disruption but can remain in their units. If a unit is directly affected by construction (rare), you may need to provide temporary relocation at your cost.
