LA Seismic Retrofit Ordinances 183893 and 184081 (2026)
Los Angeles has two mandatory seismic retrofit ordinances — and April 2026 is the hard deadline for the first wave of soft-story buildings. Here's who's affected, what it costs, and what rebates apply.
Ordinance 183893 — soft-story retrofit
Applies to wood-frame multi-family buildings with tuck-under parking, 2+ stories, 2+ units, built before 1978.
13,500 buildings subject to the ordinance.
Priority 1 (16+ units or 3+ stories) — first wave, April 2026 compliance deadline.
Priority 2 (ground-floor commercial) — later wave.
Priority 3 (all other soft-story) — latest wave.
Non-compliance: LADBS can restrict Certificate of Occupancy, impose daily fines, post the building as substandard, and ultimately condemn.
Ordinance 184081 — non-ductile concrete
Applies to 1,500 non-ductile concrete buildings built before modern seismic code.
Year 3 structural evaluation deadline.
Year 25 completion deadline.
Cost: $200K–$1M+ per building for engineering + retrofit construction.
Soft-story cost ranges
4–8 unit buildings: $20K–$75K.
10+ unit buildings: $80K–$160K.
Labor represents 70–75% of total retrofit cost in LA.
Structural steel has jumped 10–15% post-2025 wildfires, compressing budgets.
EBB (Earthquake Brace + Bolt) residential rebates
$3,000–$7,000 rebates for single-family homes built before 1980.
Covers foundation bolting and cripple-wall bracing.
2025 expansion extended eligibility to rental properties.
Application opens annually; funds exhaust fast (usually within 30–60 days of opening).
Typical retrofit process
Structural engineering assessment — 2–4 weeks.
LADBS permit submission and plan-check — 4–8 weeks for soft-story.
Construction — foundation bolting 2–5 days; soft-story steel moment frames 4–16 weeks.
Final inspection and Certificate of Occupancy.

Ask Baily — pre-seeded for this topic.
LA Seismic Retrofit Ordinances 183893 and 184081 (2026) — scoped by Baily.
Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon's rim.
He wasn't the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily's contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily's beads.
That's what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner's real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That's our vibe too.
