Location: Gardena, CA — 19210 S Vermont Ave, Building E, Gardena, CA 90248 (on-site daily)

Job Type: Full-Time

Pay: $65,000–$75,000/year, based on experience

About the Role

ADU Express is looking for an organized, detail-oriented Construction Administrative Assistant to be the administrative backbone of our projects. You'll support project managers, superintendents, and field teams — owning document control, subcontractor compliance, and day-to-day job-cost tracking so projects stay on time and on budget.

What You'll Do

• Own document control: organize, track, and distribute submittals, RFIs (requests for information), change orders, contracts, and permits
• Keep subcontractors compliant: collect, review, and track Certificates of Insurance, W-9s, and lien waivers
• Support project financials: process vendor invoices, match purchase orders, code expenses to job numbers, and assist with weekly payroll data entry
• Be the reliable point of contact: answer incoming calls, route messages, and keep field crews, subcontractors, vendors, and clients connected
• Keep schedules on track: book inspections, safety meetings, and project milestones, and track critical permit and approval deadlines

Required

• 3–5 years of administrative experience in the construction industry
• Working knowledge of construction documents — submittals, RFIs, change orders, permits
• Strong organization and attention to detail; you'll be juggling deadlines across multiple active projects
• Able to work on-site daily at our Gardena office

Preferred

• Hands-on experience with subcontractor compliance (Certificates of Insurance, lien waiver tracking)
• Experience with job costing, purchase-order matching, or payroll support

Compensation & Growth

• $65,000–$75,000/year, depending on experience
• Free Welcome+ membership for up to 12 months while actively employed — includes $0 cost telemedicine with unlimited 24/7 access, counseling support, prescription discounts, dental (Aetna Dental Access®), and vision. Covers you and your family (spouse + children under 26).
• A seat at the operational center of a fast-growing design-build firm — your work touches every active project
