ADU Structural Plans Built for Permit Review.

Detached ADUs, junior ADUs, and garage conversions all need engineered foundations, framing, and a lateral system before a city will issue a permit. We prepare the structural drawings and calculations your submittal requires, coordinated with your architectural plans.

The deliverables for this scope

Structural plans, calculations, and clear scope for Bay Area projects.

Structural plans

A stamped structural drawing set for your ADU: foundation, floor and roof framing, and the lateral system, coordinated with your architectural drawings.

Structural calculations

Supporting gravity and lateral calculations documenting how the design meets code, prepared for review by your building department.

Foundation and framing details

The connection and detail drawings your contractor builds from, covering foundation type, anchorage, shear walls, and framing members.

Engineering that keeps the project moving

Clear structural scope before construction

We define what the structure actually requires up front, so the work is priced and built against a defined scope instead of assumptions.

Drawings and calculations for permit submittal

You receive stamped structural drawings and supporting calculations prepared for submittal to your local building department.

Support for homeowners, architects, and contractors

We coordinate with whoever is on your team, or work directly with you if the project has no architect yet.

Familiarity with Bay Area projects

Our work is concentrated in Bay Area jurisdictions, from hillside lots and older housing stock to seismic requirements.

Questions we hear most

What information do you need to quote an ADU?

The property address, the type of ADU (detached, garage conversion, or junior ADU), approximate size, and any drawings you already have. Architectural plans, a site plan, or even photos and sketches help us scope the engineering accurately.

Are the drawings and calculations ready for permit submittal?

Yes. We prepare stamped structural drawings and calculations formatted for submittal to your local building department. Permit approval is issued by the city, not by us, and we support you through any comments they return.

Do I need architectural plans before you start?

Architectural plans make the engineering more efficient, but they are not always required to begin. If you do not have them yet, we can review what you have and tell you what is needed before structural work starts.

Which areas do you serve?

We work across the Bay Area, including Oakland, San Francisco, Concord, Berkeley, Alameda, Walnut Creek, Fremont, and San Jose. Availability depends on project scope and location.

How are site inspections scheduled?

We review your project details first. If an on-site visit is needed for the scope, we schedule it after that review rather than booking inspections up front.
