Repair recommendations and construction drawings
We provide repair recommendations and, when needed, code-compliant construction drawings. Recommendations address the repair work; drawings provide construction details when the job requires them.
Walnut Creek permit requirements
For Walnut Creek permit applications received from January 1, 2026 onward, we work to the 2025 California Building Code and 2025 California Residential Code.
For retaining-wall work, we check whether the wall supports a surcharge, such as sloping ground or a parking area. A wall supporting a surcharge requires both a building permit and a site development permit. The City also requires its design to be prepared by a licensed architect or registered civil or structural engineer.

FAQs
Basic structural inspections typically range from $350 to $800. Foundation inspections and reports cost $300 to $750. Load-bearing wall analysis or beam calculations run $250 to $1,000. Residential engineering plans range from $500 to $3,000, while full drawings for additions can reach $2,000 to $5,000. Hourly rates fall between $70 and $250. Prices depend on project scope, site access, and required documentation.
Demand often exceeds supply in many areas because licensed structural engineers handle specialized work like load calculations, foundation assessments, and code compliance. Smaller firms may have limited availability, and not all civil engineers focus on residential structural issues. Checking local licensing boards and professional directories can help locate qualified professionals for specific needs.
A structural engineer inspects visible elements from foundation to roof framing, reviews building history, measures elevations, and analyzes loads. They size beams, posts, and connections, calculate required footing upgrades, and document observations with notes and photos. Their work ensures safety and code compliance for modifications like wall removals or additions.
