Commercial Construction
How Long Does a Commercial Build-Out Take?
November 20, 2025 · 6 min read
The honest answer is that construction is rarely the long pole. Permitting, landlord approvals and long-lead equipment usually decide when a space opens.
Typical construction durations
Assuming permits are in hand and materials are released:
- Small retail or café (under 2,500 SF): 6–9 weeks
- Office (5,000–15,000 SF): 10–18 weeks
- Restaurant (3,000–6,000 SF): 12–20 weeks
- Medical or dental clinic: 12–20 weeks
- Warehouse interior with office: 8–16 weeks
What controls the critical path
Permit issuance, rough-in inspections, switchgear and HVAC equipment delivery, and landlord-controlled access windows.
How to compress safely
File early, release long-lead packages during design, prefabricate where possible, and lock finish selections before construction documents are complete. Adding crews to an unsequenced job just adds cost.
Frequently Asked Questions
Can construction and permitting overlap?
Partially — protection, survey and some demolition can proceed under the right filing while full permits are processed.
