Fast, clean build outs that hit occupancy dates in occupied buildings." url: "https://hanenburg-drywall.vercel.app/services/tenant-improvement-drywall" section: "Services" business: "Hanenburg Drywall" location: "Irvine, California" updated: "2026-09-25" --- # Tenant Improvement Drywall in Orange County Tenant improvement drywall covers interior build outs and reconfigurations for commercial tenants. TI work is defined by fixed occupancy dates, work inside buildings that remain occupied, and demising and corridor assemblies that must satisfy inspection. Tenant improvement work runs against a date that does not move. A lease starts, a tenant has staff arriving, and the certificate of occupancy has to be in hand. Everything about how a TI job is run follows from that. The complications are usually the building rather than the work. Access is restricted to certain hours. Freight elevator time has to be booked. Other tenants are working on the floors above and below. Corridors have to stay clean and passable. None of that is difficult, but all of it has to be planned rather than discovered on day one. The technical content is mostly demising walls, corridor assemblies, and partition layouts, which means rated and acoustic assemblies that will be inspected. We build those to their listed details and document them, because a failed inspection on a TI job costs occupancy days that nobody has spare. ## Why this matters - Schedule built backward from the occupancy date - After hours and restricted access work accommodated - Demising and corridor assemblies built to listed details - Corridors and common areas kept clean and passable - Documentation ready for inspection rather than assembled afterward ## Our Process 1. **Scope Walkthrough**: We walk the project, measure, review existing conditions, and confirm finish levels and textures room by room. 2. **Written Estimate**: A written scope with explicit inclusions and exclusions, finish level by area, materials, and a realistic schedule. 3. **Protection and Mobilization**: Floors, fixtures, and access routes protected, containment installed, and materials staged before work starts. 4. **Execute in Sequence**: Framing, board, finishing, and texture completed in sequence with quality checked at each stage rather than only at the end. 5. **Punch and Walkthrough**: Raking light inspection, punch list completion, full cleanup, and a walkthrough before the work is signed off. ## What's Included - Drawing review and building rule coordination - Demolition of existing partitions where required - Metal stud framing and layout - Blocking for millwork, equipment, and displays - Board installation including rated and acoustic assemblies - Firestopping and acoustic sealing - Finishing to specified level - Punch completion and closeout documentation ## Frequently Asked Questions ### Can you work nights and weekends for a TI project? Yes, and on many TI jobs that is the only way the building will allow the work. We plan around building access rules, freight elevator availability, and neighbouring tenant operations from the outset rather than discovering the restrictions after mobilizing. ### How do you handle demising walls? To their listed assembly, which typically means specified stud gauge and spacing, rated board layering, insulation, acoustic sealant at all perimeters and penetrations, and correct head of wall detailing. Demising walls carry both fire and acoustic expectations, and both get inspected or complained about, so they are worth building properly the first time. --- **Hanenburg Drywall** 12 Elksford Ave, Irvine, CA 92604 Phone: (949) 446-1300 Email: info@hanenburgdrywall.com Hours: Mon to Fri, 8:00am to 4:00pm Serving all of Orange County with no travel surcharge.
