If you own a duplex or small apartment in Silver Lake, you have likely heard about Los Angeles’ soft-story retrofit rules. You want to protect your building and your tenants, but you also want to avoid overspending on work you do not need. You are in the right place. In this guide, you will learn how the city’s program applies to Silver Lake properties, what a typical project looks like, how to control scope and budget, and what to watch for with permits and tenants. Let’s dive in.
What counts as a soft-story in LA
A soft-story building is a low-rise wood-frame structure with a first floor that has large openings and limited walls. Think tuck-under parking, wide garage doors, or open storefronts. Those big openings create a weak first story that can sway or collapse during an earthquake.
Los Angeles requires certain wood-frame residential buildings with two or more units to be strengthened so they perform better in earthquakes. You can review the city’s Mandatory Retrofit Programs and check program details and status on the LADBS Mandatory Retrofit Programs page.
If you never received a city notice but think your building qualifies, look up your address in LADBS records or contact the department. Many original phased deadlines have passed, so it is smart to confirm your property’s current status.
How the LA program works
The intent is straightforward. The city wants weak or open-front first stories reinforced so the building can better resist lateral shaking. Notices historically went to affected owners and included next steps and compliance timing. If you are unsure where you stand, start by verifying your address with LADBS and ask about remaining compliance or enforcement steps.
Common soft-story solutions include steel frames or added shear walls to strengthen that open first level. The goal is to increase lateral capacity while keeping your construction footprint as targeted as possible.
Step-by-step timeline for small buildings
Every building is different, but here is a realistic timeline for duplex to six-unit properties in Silver Lake.
1) Research and decisions, 1 to 2 weeks
- Confirm LADBS program status and any outstanding orders.
- Gather building records like original plans or past repairs.
2) Hire a structural engineer, 2 to 6 weeks
- Engage a licensed structural engineer who has done soft-story projects in LA.
- Expect a site visit and a conceptual plan with options and rough cost ranges.
3) Design and construction documents, 4 to 12 weeks
- Your engineer prepares plans and calculations for plan check.
- Simpler single-bay retrofits move faster than complex multi-bay designs.
4) Plan check and revisions, 4 to 16+ weeks
- LADBS review can take several weeks to several months.
- Plan on a round or two of revisions if the city requests clarifications.
5) Permit issuance, 1 to 4 weeks
- After plan check clearance, permits are typically issued within a few weeks.
6) Construction, 2 to 12+ weeks
- Duplexes and small buildings often complete faster.
- Extra foundation work, tenant access needs, or hidden damage can extend the schedule.
7) Inspections and final sign-off, 1 to 4 weeks
- Multiple inspections occur during construction.
- You will receive completion sign-off after passing final inspection.
Common delays stem from extensive plan-check revisions, foundation upgrades, discovery of termite or rot, tenant relocation issues, and contractor scheduling.
What your retrofit might include
A soft-story retrofit focuses on the first story so it resists sideways forces during shaking.
Structural elements you will likely see
- Steel frames or steel columns and beams at open bays.
- Engineered plywood shear walls where there is enough wall length.
- New or enlarged concrete footings to support added loads.
- Anchor bolts and hold-down hardware that tie wood framing to the foundation.
- Bracing for perimeter elements and exterior stairs.
- Local steel plates, straps, and blocking for targeted reinforcement.
Incidental work that often comes with it
- Opening walls or ceilings and then patching finishes.
- Repairs for hidden damage like rot or termite issues.
- Temporary utility moves where walls are opened.
- Safe access solutions or short-term tenant relocation if needed.
Scope control tactics
- Ask your engineer for a targeted, code-compliant retrofit that minimizes interior tear-out.
- Separate “required seismic work” from optional finish upgrades in your bid.
- Request two or three compliant design options, such as steel frames versus engineered shear walls, and compare costs.
- Consider focused solutions at the actual weak bays instead of full-perimeter replacements when the engineer approves.
For technical background on how these buildings perform and retrofit strategies, see the federal guidance in the FEMA report P-807.
Budgeting and cost drivers
No two projects price the same, and exact figures depend on your building. That said, a few drivers have the biggest impact on cost:
- Number and width of first-floor openings. More and wider openings often require larger frames.
- Foundation condition and need for new footings or underpinning.
- Building size, unit count, and total area.
- Access and site constraints common in Silver Lake like tight lots or limited staging.
- Level of finish restoration and incidental interior work.
- Engineer and contractor fees, plus city plan-check and permit fees.
- Unforeseen repairs uncovered during demolition.
A practical budgeting approach:
- Start with an engineer’s conceptual scope and rough cost range before full design.
- Ask for a minimum compliant scheme and a moderate scheme to avoid over-design.
- Include a contingency of 10 to 20 percent. Increase to 20 to 30 percent if conditions are unknown or tenant relocation is likely.
- Break out line items for engineering and design, structural construction, foundation work, permits and inspections, tenant-related costs, finish restoration, and contingency.
Financing options worth exploring include bank construction loans, HELOCs for owner-occupants, or commercial loans for rental properties. Programs evolve, so check the LADBS Mandatory Retrofit Programs page and city announcements for any current assistance or fee details.
Permits, tenants, and legal must-knows
All seismic work requires permits, plan check, and inspections through LADBS. Do not start construction without approved permits. Use a licensed structural engineer and a licensed general contractor with soft-story experience, and verify insurance and workers’ comp.
Los Angeles also has tenant protection rules. Significant rehabilitation that displaces tenants can trigger relocation assistance and notice requirements, and even short-term work must meet habitability standards. Review the Los Angeles Housing Department’s guidance on rent stabilization and relocations through the LAHD website and plan communications early.
If your building is a historic resource or sits in a preservation overlay, coordinate with City Planning or Cultural Affairs. You may need to preserve or restore architectural elements along the façade while completing structural work.
Silver Lake details to plan around
Silver Lake properties often sit on narrow lots with limited staging space. Ask your contractor about material deliveries, temporary parking solutions, and any street use permits the site may require. Hillside topography in some pockets can also affect foundation access and the choice of equipment.
Architectural character is part of why residents choose Silver Lake. If your building has notable street-facing details, plan finish restoration that respects the original style after the retrofit. Your engineer and contractor can often tuck steel frames behind existing lines and restore finishes to blend with the design.

Why this matters in earthquake country
Silver Lake sits within Southern California’s active seismic region. Shaking intensity and frequency vary, but the risk is real. Strengthening a soft story addresses one of the most common wood-frame vulnerabilities. To understand the broader hazard context, explore the USGS Earthquake Hazards Program.
Your next steps
- Confirm your property’s status with LADBS and gather records.
- Bring in a licensed structural engineer for a targeted concept and options.
- Separate must-do seismic work from nice-to-have upgrades before you bid.
- Plan tenant communications early and budget for contingencies.
