The Math

The cost of doing nothing.

Every week past the deadline adds penalties, liability, and pressure on title. The arithmetic gets worse, not better.

01 · Daily Fines

Penalties compound day by day.

LADBS administrative fines escalate daily. 90 days of non-compliance equals tens of thousands in penalties, with no statutory cap.

02 · Vacate Order

Tenants relocated at your expense.

LADBS can revoke your Certificate of Occupancy and order tenants relocated at your expense. Relocation for a 6-unit building: $80K+ before any retrofit work begins.

03 · Title Lien

Sale and refinance blocked.

Unpaid fines become recorded liens with LA County. Title clouds block any sale or refinance until paid.

Submitted plans stop the clock. Engineering compliance in 14 days. Cheaper than non-compliance, on every axis.

FAQ

Common questions.

Don't see your situation? Send it via the form below — the PE who would run your project answers the email.

My deadline already passed. Am I out of options?
No. LADBS prefers compliance over penalty, and submitting plans is the single fastest way to demonstrate good faith and slow the enforcement clock. We have helped owners with overdue Orders to Comply file plans and re-enter the compliance pathway. The longer you wait, the harder it gets — but waiting one more month is far worse than starting today.
How do I know if my building is covered by Ordinance 183893?
Three criteria: built before January 1, 1978; wood-frame construction; three or more residential units; and a "soft, weak, or open-front" first floor (tuck-under parking, ground-floor commercial space, or large window/door openings without adequate shear walls). If your building meets all three, it is almost certainly in scope. Send us the address and we will confirm against the LADBS list before you commit to anything.
What is the difference between Priority 1 and Priority 2?
Priority 1 covers buildings with 16 or more units, or three or more stories with ground-floor commercial occupancy. Their deadline was April 2024. Priority 2 covers all other soft-story buildings — typically two- or three-story residential buildings with tuck-under parking and fewer than 16 units. The Priority 2 deadline was April 2026.
How much will the actual retrofit construction cost?
Independent of engineering, construction typically runs $60,000 to $200,000 for small and medium Priority 2 buildings. Cost per unit averages $5,000 to $15,000. Cost depends on building size, site access, choice of retrofit system, and foundation conditions. We are an engineering firm and do not perform construction — but we will refer you to two or three qualified contractors after plans are stamped.
Can I pass retrofit costs to my tenants?
If your building is under LA's Rent Stabilization Ordinance (RSO), yes — partially. The LAHD Seismic Retrofit Work Cost Recovery Program allows pass-through of up to 50% of approved retrofit costs, divided equally among all rental units, capped at $38 per month per unit for 120 months. You must apply within 12 months of completing the retrofit. Properties not under RSO are governed by lease terms; consult a real estate attorney before relying on cost recovery in your underwriting.
Why is your fee lower than national firms but higher than the $5K quotes I have seen?
Because we are an established California PE-licensed firm that uses AI-accelerated production to reduce engineering hours, not an unlicensed shop racing to the bottom. Engineers quoting $5,000 for 40-unit jobs cannot deliver real engineering at that price, and plans frequently fail plan check, costing owners weeks of rework. National firms charge $15,000 to $30,000 because they overhead-load every project. We sit in between: fast, fixed-fee, properly licensed, properly stamped.
What happens after plans are stamped?
We submit plans to LADBS e-Plan check on your behalf. LADBS plan check typically takes 3 to 6 weeks. We respond to two rounds of plan check corrections at no additional cost. Once plans are approved, you select a contractor (we can refer two or three), pull the permit, and begin construction. Construction typically takes two to four months for a Priority 2 building.
Do you handle the Tenant Habitability Plan (THP)?
Not by default. LA requires a Tenant Habitability Plan for any retrofit affecting RSO units. THP filing is a separate service we offer at $1,500 flat, or you can use a tenant relocation specialist. THP is required before construction starts, not before plans are submitted, so you have time to address it during plan check.
