Contingency

A contingency is a planned budget reserve in a commercial buildout, expressed as a percentage of hard costs, that absorbs unexpected expenses without derailing the project. Construction projects almost always encounter unforeseen conditions — hidden structural damage, code compliance requirements discovered mid-project, material price changes, scope additions — and a contingency buffer is what separates projects that finish on budget from those that run over.

Key Facts

  • 1Industry standard contingency for commercial tenant improvements is 10–15% of hard costs; first-time buildouts in older buildings or complex food service spaces should budget 15–20%
  • 2Unused contingency is not a savings account — it is discipline. Projects that spend every contingency dollar are actually running over budget; the contingency exists to absorb the unpredictable without emergency re-financing
  • 3Lenders and investors evaluate buildout budgets for adequate contingency — a budget with no contingency line is a red flag for underfunding

What Contingency Covers

  • Unforeseen conditions in the existing structure (mold, asbestos, failed plumbing discovered during demolition)
  • Code upgrade requirements triggered by the permit process (sprinkler system upgrades, ADA path-of-travel requirements)
  • Scope additions requested after the GC contract is signed — these become change orders billed at a markup
  • Material price escalation between bid and delivery for long-lead items
  • Subcontractor cost overruns on allowance items (tile, lighting, millwork) where the final selection exceeds the budgeted allowance
  • Re-work required by failed inspections

Contractor Contingency vs. Owner Contingency

In GMP (guaranteed maximum price) contracts, the contractor holds their own internal contingency for cost overruns within their scope. The owner maintains a separate contingency for scope changes, owner-requested additions, and unforeseen conditions outside the contractor's risk. These are distinct pools and should be budgeted separately.

In lump-sum contracts — more common for smaller TI buildouts — there is no contractor contingency; any overrun becomes a change order billed to the owner at a markup. This makes owner contingency even more important in lump-sum projects.

Frequently Asked Questions

What if I don't use my contingency?

Unspent contingency is a positive outcome — it means your project came in under budget. Some business owners redirect unspent contingency to FF&E, opening inventory, or working capital. Others keep it in reserve for early-operation repairs. It's your money; the contingency just ensures it's available if construction needs it.

Should contingency be included in the TIA calculation?

No. TIA is a hard-cost reimbursement mechanism, not a contingency fund. Budget your TIA against confirmed hard costs. Maintain a separate owner contingency in cash that isn't dependent on TIA disbursement timing.

How do I handle contingency in a tight budget?

If you can't afford a 15% contingency, reduce scope to create the reserve rather than eliminating the contingency entirely. A smaller, well-funded buildout is safer than a larger one with no financial cushion. Contingency is the difference between a construction surprise and a project failure.
