The Valley's Most Common Structural Weakness
Drive any block of apartment buildings in Van Nuys and you'll see the pattern: two or three stories of units sitting over open tuck-under parking, the whole front of the building carried on slender columns. That open level is a soft story — dramatically weaker than the floors above it — and in a strong quake it's where these buildings fail.
The 1994 Northridge earthquake made that failure mode famous a few miles from here, and it's why Los Angeles adopted a mandatory retrofit ordinance covering thousands of pre-1978 wood-frame soft-story buildings citywide. Van Nuys, with its dense mid-century apartment stock along Sepulveda, Vanowen, and Sherman Way, holds a heavy share of that list.
If you own one of these buildings, the retrofit isn't a question of whether — it's a question of when, and on whose schedule.
What the City Order Means — and What the Fix Looks Like
Owners in the program receive an Order to Comply from LADBS that starts a multi-year clock with staged deadlines: submit engineered plans, pull permits, complete construction. Miss the milestones and penalties stack while the structural risk stays exactly where it was.
The fix itself is well understood. A licensed structural engineer analyzes the building and designs the strengthening; construction then typically adds steel moment frames at the open parking bays, plywood shear walls where solid walls exist, connection hardware tying the upper floors into the new strength, and concrete footings under all of it. The goal isn't to make an old building new — it's to give the weak story enough capacity to keep the building standing and repairable after a major quake.
We build these retrofits as part of our broader structural and residential construction work across the Valley — the same trade skills as our foundation and framing projects, applied to the building type Van Nuys has most.
Tenants Stay; Parking Suffers Briefly
The question every owner asks first: do the tenants have to leave? Almost never. Retrofit work lives at the ground level — parking bays, footings, columns — so occupied units above stay occupied. What tenants actually experience is a few weeks of daytime construction noise and a temporary parking shuffle while bays are trenched and framed.
Managing that well is half the job. Work gets phased bay by bay so part of the parking stays usable, noisy operations get scheduled inside reasonable hours, and tenants get a plain-language timeline before the first crew shows up. A retrofit that keeps rent flowing and tenants informed costs the owner far less, in every sense, than one that treats the building like an empty site.
From Order to Sign-Off on One Contract
The compliance path has real steps — structural engineering, LADBS plan check, permits, construction, staged inspections, and the final sign-off that formally closes your order. We run that path end to end as one accountable licensed contractor: coordinating the engineer, carrying the plans through the city, building to the stamped drawings, and walking the inspector through each stage.
Owners who start early in their compliance window get calm schedules, competitive pricing, and time to phase costs. Owners who start at the deadline get none of those. If your building has an order — or you suspect it's on the list — the free first step is a site walk and a written estimate laying out engineering, permits, construction, and timeline in one document.
A completed retrofit closes the city file, strengthens the asset you already own, and settles the question the next earthquake will otherwise ask for you.

Frequently Asked Questions
What is a soft-story building?
A building whose ground floor is significantly weaker than the floors above — classically an apartment building perched over open tuck-under parking on skinny columns. In an earthquake, that open level can rack sideways and collapse under the weight above it. The Valley learned this the hard way in the 1994 Northridge earthquake, which is why these buildings are now regulated.
Is a retrofit mandatory for my Van Nuys building?
If you've received an Order to Comply from LADBS, yes — Los Angeles's mandatory soft-story retrofit ordinance covers thousands of pre-1978 wood-frame buildings with weak open ground stories, and Van Nuys has a heavy share of them. The order starts a multi-year compliance clock with staged deadlines for plans and construction. Ignoring it stacks up penalties and leaves the building uninsurable-in-practice.
What does the retrofit work actually involve?
Strengthening the weak story so it can carry the building's seismic load. Typical scope: new steel moment frames at the open parking bays, plywood shear walls where walls exist, hardware tying the floor above to the new strength below, and new concrete footings under it all — built to plans stamped by a licensed structural engineer. Most of the work stays at the ground level.
Do tenants have to move out during a retrofit?
Almost never. The work concentrates in the parking level, so upstairs units stay occupied throughout. The real tenant impacts are parking disruption and daytime noise for a few weeks, both of which get scheduled and communicated in advance. We've found buildings run smoothest when tenants get a simple one-page timeline before crews arrive.
How long does a soft-story retrofit take?
Construction itself typically runs several weeks to a few months depending on how many bays need frames and footings. The full compliance path — engineering, LADBS plan check, permits, construction, and final sign-off — is usually measured in months. Starting early inside your compliance window keeps the schedule calm instead of deadline-driven.
Does a retrofit protect the building's value?
It protects the whole investment. A completed, signed-off retrofit closes out the city order, typically improves the building's insurability and financing picture, and removes the collapse-risk discount buyers apply to unretrofitted soft-story properties. It's one of the few mandated expenses that directly defends both lives and asset value.
