Seismic retrofit construction
Moment frames, cantilever columns, shear-wall reinforcement, and structural anchoring for soft-story ordinance compliance.
Services
Three services. One licensed team.
Cal Retrofit operates in the structural-compliance corridor of Southern California construction. Every service below is delivered end-to-end under one license.
Each Cal Retrofit service is delivered as a complete program: permit, fabrication, install, certification, with one point of accountability for the property owner.
S01 · Service
Seismic retrofit
Soft-story retrofits under city ordinance. Permitting, steel installation, and city inspection, handled end-to-end, with engineering by our partner Naxa.
- Serves
- Owners of soft-story multifamily, mixed-use, and tuck-under-parking buildings subject to mandatory retrofit.
- What we provide
- Plan check coordination, steel moment frames, cantilever columns, shear wall reinforcement, and final certification.
- Why it matters
- When ground shaking starts, soft-story buildings fail first. Retrofit converts a known structural liability into a code-compliant, insurable building.
S02 · Service
Balcony repair and recertification
SB-721 and SB-326 exterior elevated element repair, waterproofing, and recertification. The licensed contractor who executes the fix after the inspection.
- Serves
- Multifamily owners (SB-721) and HOAs (SB-326) with balconies, decks, stairways, walkways, or elevated entry structures that need repair or recertification.
- What we provide
- Repair scope, structural remediation, waterproofing, permit coordination, and certified repair execution. Licensed inspection reports handled with our engineering partner Naxa.
- Why it matters
- Missing the deadline means fines, insurability issues, and personal exposure if an element fails. One vendor for the repair-through-recertification chain.
S03 · Service
ADUs, through our sister companies
For dedicated ADU design and delivery, our sister companies lead: ADU Concepts for single-family and multifamily ADUs, and LyteMods for panelized light-gauge-steel ADU homes. Cal Retrofit provides the structural, foundation, and permitting support where an ADU pairs with retrofit work on the same lot.
- Serves
- Property owners exploring an accessory dwelling unit alongside compliance or foundation work.
- What we provide
- A direct handoff to ADU Concepts and LyteMods, plus the structural, foundation, and permitting support Cal Retrofit already performs on the same lot.
- Why it matters
- ADUs are the fastest, most reliable way to add legal housing to an existing lot in California. Our family of companies covers the whole path.

Waterproofing that protects the whole building.
Water is the number-one cause of structural deterioration in Southern California buildings. Waterproofing is not a finish coat, it is building maintenance that protects the structure underneath.
It protects the structure
Water intrusion drives dry rot, steel corrosion, and mold, the exact damage that fails balconies and decks under SB-721 and SB-326. Stop the water and you stop the failure.
It is the cheapest work on the building
Once water reaches the framing, the repair is no longer a coating, it is structural. Waterproofing done right, on schedule, is a fraction of the cost of the damage it prevents.
The right system depends on the building
Coastal salt air, seasonal rain, and irrigation each attack the envelope differently. We select the system by the building's location, exposure, and use, not one product for every surface.
Applications we install
01
Balcony and deck coatings
Traffic-bearing waterproof membranes for exterior elevated elements: decks, balconies, walkways, and stair landings. The system that keeps water off the framing and keeps EEEs compliant after repair.
02
Below-grade and foundation
Membranes, coatings, and drainage for basements, retaining walls, and foundations, stopping the water intrusion that undermines a structure from the ground up.
03
Building envelope and walls
Flashings, sealants, coatings, and air-and-water barriers that keep the wall assembly dry, protecting sheathing, framing, and interior finishes.
04
Roof decks and flat surfaces
Fluid-applied and sheet systems for roof decks, podium slabs, and flat transitions where standing water and foot traffic meet.
Single-component or reinforced, fluid-applied or sheet, we match the system to the building. One product does not fit a coastal balcony and a below-grade wall.
04 · Capabilities
One accountable team.
The chain that keeps a Cal Retrofit project moving: permitting, fabrication, installation, and closeout under one license. Structural engineering and balcony inspection reports are handled by our sister company Naxa.
C02
Permitting and plan check
We pull the permits. We respond to plan check. We coordinate every back-and-forth with the city so the project keeps moving.
C03
SB-721 and SB-326 balcony repair
Repair, structural remediation, waterproofing, and recertification of exterior elevated elements. Inspection reports handled with our engineering partner Naxa.
C04
Structural steel installation
Moment frames, cantilever columns, beam-and-post systems, and steel reinforcement for seismic retrofit and structural repair.
C05
Foundation repair and waterproofing
Foundation repair, leveling, and stabilization, plus waterproofing for exterior elevated elements and below-grade structures.
C06
Field execution
Licensed and insured crews. Documented quality control. Communication that doesn't disappear once the contract is signed.
05 · Also available
Additional construction scope.
Beyond the three primary services, Cal Retrofit handles related general-contractor scope for owners who already trust us with their property.
01 · Scope
Foundation repair and leveling
Structural foundation repair, leveling, and stabilization for residential and multifamily properties across Southern California. The structural work that keeps a retrofit sound from the ground up.
02 · Scope
Drainage and grading
Surface and subsurface drainage, area drains, and grading corrections that move water away from the structure before it ever becomes a waterproofing problem.
03 · Scope
Dry rot and structural repair
Removal and replacement of water-damaged framing, sheathing, and structural members uncovered during balcony, deck, and envelope repair.
Available as bolt-on scope on retrofit, balcony, or foundation contracts, or as standalone work. Ask during your free site assessment.
