"How long will this take?" is as important as "what will it cost" — especially when you're paying rent on a space you can't yet occupy. While every project differs, the phases are consistent, and understanding them helps you set a realistic move-in target.
Before construction starts, the space needs a design that reflects how your business actually works: layout, finishes, and any specialized requirements. This phase moves as fast as decisions get made, so timely sign-offs keep things on track.
As covered in our permitting guide, LADBS plan check is often the least predictable phase. Building it into the schedule early — rather than discovering it late — is the difference between an on-time and a delayed project.
Demolition, framing, MEP rough-in, inspections, finishes, and final details. The duration scales with scope: a straightforward open-plan office moves quickly, while medical, lab, or heavily customized spaces take longer due to systems and inspections.
Final inspections, any corrections, and closeout precede your certificate of occupancy. Planning for inspection windows avoids last-minute surprises right before move-in.
The usual culprits: slow design decisions, permit corrections, long-lead materials ordered too late, and change orders introduced mid-build. Most delays are avoidable with early planning and clear communication.
ASEP gives you a clear timeline up front and manages scope, permitting, and procurement to protect it. Our reputation is built on finishing on schedule — including work in occupied buildings where timing matters most.
A commercial office build-out moves through predictable phases: design and space planning, permitting and plan check, demolition of existing conditions, rough-in of framing and MEP systems, inspections, finishes (drywall, paint, flooring, ceilings, millwork), and final punch list before occupancy. Each phase depends on the one before it, which is why realistic sequencing — not optimism — is what keeps a project on track. Understanding these stages up front helps a business owner plan a move-in date they can actually rely on.
The most common schedule risks are permitting delays, long-lead materials and equipment, mid-project scope changes, and unforeseen existing conditions discovered once demolition opens up walls and ceilings. Custom millwork, specialty lighting, and mechanical equipment can carry weeks of lead time, so ordering early matters. A contractor who identifies long-lead items and unknowns at the start — and orders and investigates ahead of need — protects the timeline before problems surface.
Schedule protection is mostly about decisions made early: finalizing the design and finishes before construction starts, locking scope, procuring long-lead items ahead of time, and building permitting into the plan rather than treating it as a formality. Fast, clear decision-making on the client side keeps momentum — every open question that lingers is time the schedule quietly absorbs. Regular progress updates let you catch and resolve issues before they cascade.
A reliable build-out timeline lets you coordinate the rest of your move — lease overlap, IT and furniture installation, signage, and the actual relocation of staff. The safest approach is to plan move-in against a realistic completion date with a small buffer, not the most optimistic one. A contractor who commits to a clear schedule up front, and communicates as it progresses, is what makes that planning possible.
