How Long Does a Flex Space Project Take in Houston, Texas?

Flex space developments are one of the fastest commercial building types in the Houston market. Still, owners often ask the same question: how long does a flex space project actually take?

With proper planning and early contractor involvement, most flex space projects in Houston can be delivered efficiently and predictably.

Typical Flex Space Timeline in Houston

Total Project Duration: 12–18 Months

Here’s a simplified breakdown:

Planning & Pre-Development (2–4 months)Site evaluation, budgeting, zoning review, and early design. This phase is critical in Houston due to utilities, drainage, and permitting requirements.

Design & Permitting (3–6 months)Architectural and engineering drawings, detention design, and city or county approvals. Timelines vary by jurisdiction, but experienced local teams help avoid delays.

Sitework & Foundations (1–2 months)Clearing, grading, underground utilities, detention systems, and foundations. Weather and soil conditions can impact this phase.

Building Shell Construction (3–5 months)Structural steel, roofing, exterior walls, overhead doors, and storefronts. Flex buildings move quickly once the shell begins.

Interior Build-Outs (2–4 months)Office areas, restrooms, HVAC, electrical, plumbing, and fire protection. Tenant customization can affect duration.

Final Inspections & Occupancy (2–4 weeks)City inspections, fire marshal approvals, and Certificate of Occupancy.
