What We Learned from Soft Story Retrofits in SF, Oakland, and Berkeley: A Contractor’s Perspective

You see a clean set of plans. We see whatever is actually hiding under the building.

Those are rarely the same thing.

This is what we learned doing soft story work in San Francisco, Oakland, and Berkeley, and how it should shape what happens next in places like San Jose.

The Reality Under Buildings vs What Plans Show

Existing condition surprises

On paper, you have: straight foundations, clear lines of columns, easy utility relocations. In the field, we kept finding:

• Rot in sill plates and posts that were assumed “sound”
• Foundations that changed size, shape, or material mid-run
• Gas, water, electrical, and telecom lines zig-zagging exactly where new frames or walls needed to go
• Crawl spaces that were technically “accessible” but in practice required belly-crawling with inches of clearance

Lesson: if you do not invest in a real field investigation up front, you will “pay” for it in change orders, schedule hits, and tenant disruption later.

Working with Engineers on Soft-Story Design

What good collaboration looks like

The best projects are the ones where engineer and contractor collaborate early and often:

• The engineer and contractor walk the site together before final design so the drawings reflect real foundations, clearances, and utilities.
• Everyone is honest about access, equipment limits, and what will actually fit in a tight carport or garage.
• Details are drawn with constructability in mind: bolt access, tool access, shoring, sequencing, and how the crew will assemble it safely in the field.

When we work this way, we see fewer RFIs, fewer surprises, and almost no finger-pointing. The engineer’s design intent is preserved, and the building gets the performance it was designed for.

Where designs typically need field adjustments

Even with strong design, the field always reveals a few things that no one could see on paper:

• Existing gas, water, fire, or electrical lines that run exactly where a frame or wall was planned.
• Foundations that aren’t as uniform or clean as the as-builts suggested.
• Shear wall locations that would shut down critical parking or access if built exactly as first drawn.

On good teams, none of this is a problem. Drawings are treated as the starting point, not untouchable scripture. We bring back photos, measurements, and options, the engineer refines the details, and owners end up with a retrofit that is both code-correct and buildable – with less drama and fewer change orders.

Parking and Tenant Impacts in Real Life

What owners underestimated

Soft story retrofits live where people park their cars and walk to their homes. Owners routinely underestimated:

• How upset people get when parking disappears for weeks
• How much construction activity, noise, and blocked paths affect day-to-day life
• The coordination required for deliveries, trash pickup, and emergency access

Phasing strategies that actually worked

What worked best in the Bay Area:

• Clear written schedules to tenants before work starts
• Phasing work by bay or side so some parking remains available
• Clearly coordinating the loudest or most disruptive tasks
• Temporary parking plans communicated early

When owners owned the disruption and communicated with all tenants in advance, projects went smoother.

Common Construction Challenges

Tight sites, access, and existing utilities

Urban soft story work means: narrow lots, shared driveways, overhead wires, and utilities everywhere. We know to:

• Plan material staging and debris routes before demo
• Expect at least one “invisible” utility in the wrong place
• Budget time for utility coordination, not just structure

Foundations that are not what anyone thought

We saw:

• Shallow, offset, or stepped footings that did not match assumptions
• Old patches, brick or stone sections mixed into “concrete” foundations
• Voids, honeycombing, and prior DIY “repairs”

If you assume perfect foundations, your retrofit will be full of field changes.

If you assume weirdness and plan for it, you stay on schedule.

How Our SF/Oakland/Berkeley Experience Shapes San Jose and Future Soft-Story Work

Because we’ve already completed soft-story retrofits under real programs in San Francisco, Oakland, and Berkeley, we don’t have to learn on your building. We bundle our experience from those cities in a tighter, front-loaded process for San Jose and future programs.

Front-loaded investigation and design

On current and future projects, we:

• Treat screening and early evaluation as real design work, not just a form to file.
• Get the engineer and contractor into the same crawl spaces and carports before final design is locked.
• Do targeted, invasive investigation where it matters (foundations, utilities, odd framing) instead of assuming drawings match reality.
• Assume utilities and foundations will not be where anyone expects and plan contingencies from day one.

Result: fewer mid-project surprises, cleaner plan check, and less “field redesign” under pressure.

Clear expectations for owners, tenants, and parking

We’ve seen exactly how these jobs impact real people and operations, so we:

• Align early with owners on what disruption will actually look like – parking loss, noise windows, access paths.
• Get phasing, parking, and tenant communication decisions in writing before work starts.
• Build tenant and parking management into the scope, not as an afterthought.
• Set realistic timelines based on actual experience in other Bay Area cities, not best-case scenarios.

Result: projects that feel managed, not chaotic, and far fewer surprises for tenants and managers.

If you own or manage a soft-story building, the single smartest move you can make is to front-load reality: a real field walk, real photos, real measurements, and real conversations about disruption and timing. The more truth you face before you start, the fewer expensive surprises you buy later.
