Apartment Building Structural Engineering
Comprehensive structural engineering for apartment buildings, condominium complexes, townhomes, and multi-unit residential developments throughout California. Our licensed engineers deliver efficient, code-compliant designs for Type III and Type V construction with expert seismic engineering.
What is Apartment Building Engineering?
Apartment building structural engineering requires deep expertise in multi-unit residential construction, California seismic codes, and efficient structural system design that controls costs while meeting life-safety requirements. From 4-unit buildings to large apartment complexes, our engineers design complete structural systems including foundations, floor diaphragms, shear walls, and gravity framing optimized for repetitive unit layouts. We specialize in Type V wood-frame, Type III construction, and podium (Type I over Type V) buildings common throughout California residential development.

Frequently Asked Questions
Common questions about apartment building engineering
What construction types do you design for apartment buildings?
We design Type V-A and V-B wood-frame (most common for 2-4 story apartments), Type III-A and III-B (for taller wood-frame buildings up to 5 stories), and podium construction (Type I concrete podium with Type V wood-frame above). We also design steel and concrete structures for larger projects. The optimal construction type depends on building height, unit count, and local requirements.
How much does apartment building structural engineering cost?
Small apartment projects (4-12 units) typically range from $15,000-$30,000. Mid-size projects (12-50 units) range from $25,000-$50,000. Large or complex projects (50+ units, podium construction) range from $50,000-$75,000+. Fees reflect the extensive analysis, detailing, and coordination required for multi-unit buildings. We provide detailed proposals after reviewing your plans.
What is podium construction?
Podium construction places a concrete or steel structure (typically containing parking or commercial space) at the ground level, with wood-frame residential stories above. The concrete podium acts as the foundation for the wood structure and provides fire separation. This construction type is popular in California for maximizing density. It requires specialized structural engineering at the interface between construction types.
How do you handle seismic design for apartment buildings?
California apartment buildings require rigorous seismic design. We perform complete lateral analysis including base shear calculation, story drift checks, torsional irregularity evaluation, and diaphragm design. Shear walls with hold-downs provide lateral resistance in wood-frame buildings. We optimize shear wall placement to minimize impact on unit layouts while meeting all seismic code requirements.
How long does the engineering process take?
Structural design takes 6-12 weeks for most apartment projects, running concurrently with architectural design development. Building department plan review adds 6-16 weeks depending on jurisdiction and project complexity. Total timeline from structural design start to permit approval is typically 12-28 weeks. We align our schedule with the overall project timeline.
Do you provide construction phase services?
Yes, construction administration is a standard part of our apartment building services. This includes review of structural submittals and shop drawings, response to contractor RFIs, periodic site observations during critical construction phases, pre-pour foundation and post-tension inspections, and coordination meetings. These services ensure structural design intent is properly executed.
Can you help with value engineering?
Value engineering is integral to our apartment building design approach. We optimize structural member sizes, simplify framing layouts for construction efficiency, select cost-effective lateral systems, and coordinate with the architect to minimize structural impacts on unit plans. Efficient structural design directly reduces construction costs on repetitive multi-unit buildings.
What about fire-rated assemblies in apartment buildings?
Fire-rated floor/ceiling and wall assemblies are required between units and at corridors in apartment buildings. We design structural systems compatible with required fire-rated assemblies, including UL-listed floor/ceiling systems and fire-rated shear walls. Our framing plans reference specific fire-rated assembly designations to ensure code compliance.
