Our Structural Engineering Services
We provide detailed engineering solutions tailored specifically for ADU projects. Our work addresses every critical aspect, from the ground up, ensuring a durable and code-compliant structure.
Foundation Analysis and Design
Our foundation analysis begins with a thorough evaluation of soil conditions and site-specific factors. We determine the soil's bearing capacity and identify any challenges such as soil instability or moisture issues.
Based on these insights, we design foundations that support your ADU's weight safely and efficiently. This includes recommending appropriate footing types and depths that suit both the local geology and structural demands.
We ensure all foundation plans comply with Pasadena’s building codes. Proper foundation design is essential to prevent settling, cracking, or shifting that could compromise your ADU’s integrity.
Framing and Load-Bearing Calculations
We calculate load requirements carefully to design framing systems that handle all stresses the structure will encounter. This includes dead loads (weight of materials) and live loads (occupants, furniture, environmental pressures).
Our process involves selecting suitable framing materials and sizing beams, joists, and headers to maintain stability and safety. We incorporate shear walls and other reinforcements where necessary.
Our calculations strictly follow local building codes and engineering standards to provide balanced support without unnecessary material use. This approach optimizes structural efficiency and cost.
Seismic Reinforcement Strategies
Given Pasadena’s seismic activity, seismic reinforcement is critical. We integrate design strategies that improve your ADU’s ability to withstand earthquakes.
This includes proper shear wall placement, foundation anchoring, and flexible framing connections that absorb and dissipate seismic forces.
We use materials and construction methods that meet or exceed California’s seismic safety standards, reducing risk and enhancing occupant safety during an event.
Our Process: From Consultation to Completion
We focus on understanding your specific ADU needs, thoroughly planning structural details, and ensuring compliance through on-site inspections. Each step ensures safety, efficiency, and clear communication to meet Pasadena’s building standards.
1. Feasibility Assessment
We begin by discussing your ADU goals, site conditions, and budget. This includes reviewing existing property structures and local zoning regulations to assess project feasibility.
Our team evaluates soil conditions, foundation stability, and any potential structural challenges upfront. We provide you with a clear feasibility report outlining what can be done based on engineering limits and city codes.
This consultation allows us to tailor the design process effectively and avoid costly surprises during construction.
2. Detailed Structural Planning and Review
Once the feasibility is set, we develop comprehensive structural plans that address load calculations, foundation design, and materials selection. These plans comply with California’s seismic and building codes specific to Pasadena.
We collaborate closely with architects and contractors to integrate engineering solutions seamlessly into your ADU design. Changes and concerns are addressed during plan reviews to ensure accuracy.
All structural drawings are prepared for permit submission, helping to streamline approval from Pasadena’s building department.
3. On-Site Engineering Inspection
Our engineers conduct critical inspections during key construction phases to verify compliance with approved plans and safety standards. We assess foundation work, framing, and load-bearing elements.
Inspections minimize risks by catching issues early and confirming proper material use and workmanship. We provide detailed reports and recommendations after each visit.
This hands-on involvement supports a smooth construction process and ensures the structural integrity of the completed ADU.

Frequently Asked Questions About Structural Engineering for ADU Construction
Do I need a structural engineer for my ADU project?
Yes, California requires structural engineering for ADU projects to meet seismic safety standards and building codes. Even garage conversions need structural analysis to ensure existing foundations can handle new loads. At Pasadena Master ADU Builder, we work with licensed structural engineers on every project to ensure code compliance and smooth permit approval.
How much does structural engineering cost for an accessory dwelling unit?
Structural engineering for ADUs typically costs $3,000 to $8,000, depending on size and complexity. Simple detached units cost less, while attached ADUs or those requiring foundation work cost more. The investment prevents costly delays and ensures safety compliance.
What does a structural engineer do for ADU construction?
A structural engineer designs your ADU's framework for safety and stability. They analyze soil conditions, design foundations, specify framing details, and ensure seismic compliance. They create the stamped engineering plans required for permit approval and provide construction support when structural questions arise during building.
Can I build an ADU without structural engineering plans?
No, California law requires stamped structural engineering plans from a licensed engineer before permits are issued. Building without proper engineering violates codes, creates liability issues, and prevents passing inspections. This could result in costly retrofits or demolition.
How long does structural engineering take for ADU permits?
Structural engineering takes 2-4 weeks once architectural plans and site information are provided. Simple projects may finish in 1-2 weeks, while complex designs can take 4-6 weeks. At Pasadena Master ADU Builder, we coordinate with engineering partners early to keep your timeline on track.
