Hard Costs, Soft Costs & Contingency

Breaking a construction budget into the predictable and the unpredictable.

A development budget separates hard costs (physical construction), soft costs (design, permitting, financing, and fees), and contingency (a reserve for the unexpected), with contingency typically sized as a percentage of hard costs.

Hard Costs: The Physical Building

Hard costs are the direct, physical costs of construction: site work and utilities, foundations and structure, building systems (mechanical, electrical, plumbing), interior finishes, and the general contractor's fee and general conditions. They are usually the largest single component of a development budget and the category most exposed to material price swings, labor availability, and site conditions discovered once work begins.

Hard costs are typically documented in a detailed schedule of values — a line-item breakdown by trade or scope that later doubles as the basis for approving construction draws as work is completed.

Soft Costs: Everything Around the Building

Soft costs cover everything required to plan, approve, and finance the project that isn't physical construction: architecture and engineering fees, permits and impact or tap fees, legal and title costs, construction-period loan interest and financing fees, insurance, taxes during construction, the developer's fee, and pre-leasing or marketing costs. Soft costs are commonly discussed as a percentage of hard costs for quick sanity-checking, though the actual figure varies significantly by project type, jurisdiction, and complexity.

Because soft costs accrue over the entire development timeline — often starting well before hard construction begins — delays in entitlement or permitting tend to inflate soft costs, particularly financing costs, even when the physical scope of the building never changes.

Contingency: Budgeting for the Unknown

Contingency is a reserve set aside for costs that cannot be specifically identified in advance — unforeseen site or subsurface conditions, code changes, design errors, or price escalation between budgeting and construction. It is conventionally sized as a percentage of hard costs, with the percentage generally scaled to the level of risk and uncertainty in the project: straightforward new construction under a guaranteed-maximum-price contract typically warrants a smaller contingency than a complex renovation or a project bid before design is fully complete.

Contingency is not a slush fund for scope changes the developer wants to make; disciplined sponsors and lenders track contingency draws closely and expect it to be used only for genuinely unforeseen items.

Why Lenders Underwrite Each Category Separately

Construction lenders typically review hard costs, soft costs, and contingency as distinct line items rather than a single lump sum, because each carries a different risk profile and a different likelihood of overrun. A budget with a thin or nonexistent contingency, or one that buries financing costs inside a vague soft-cost figure, is a common underwriting red flag — it suggests the sponsor's total development cost estimate may understate what the project will actually require to complete.

Typical Hard Cost Items

  • Site work, grading, and utilities
  • Foundation and structural shell
  • Building systems (mechanical, electrical, plumbing)
  • Interior finishes
  • General contractor's fee and general conditions

Typical Soft Cost Items

  • Architecture and engineering fees
  • Permits and impact/tap fees
  • Legal and title costs
  • Construction-period loan interest and financing fees
  • Developer fee
  • Insurance and taxes during construction

An Underfunded Contingency Is a Common Point of Failure

When a project runs into unexpected site conditions, code changes, or price escalation without an adequate contingency reserve, the shortfall typically has to be covered by additional equity, a loan increase, or a value-engineering redesign — any of which can delay the project or erode the developer's projected profit.

Frequently Asked Questions

What is the difference between hard costs and soft costs in construction?

Hard costs are the physical costs of building (site work, structure, systems, finishes, and the general contractor's fee), while soft costs are everything else needed to plan, permit, and finance the project, such as architecture and engineering, permits, legal fees, construction-period interest, and the developer's fee.

How is a construction contingency typically sized?

Contingency is usually budgeted as a percentage of hard costs, with the exact percentage scaled to project risk — new construction under a guaranteed-maximum-price contract typically warrants a smaller contingency than a complex renovation or a project bid before design is fully complete.
