Retail Space Build-Out Cost Estimator
Estimate the total cost to build out a retail space, including construction, fixtures, mechanical systems, and soft costs. Enter your space details below to get a comprehensive cost breakdown.
Formula & Methodology
Step 1 — Adjusted Base Rate:
Adjusted Rate ($/sq ft) = Base Finish Rate × (1 + Condition Adjustment) × Retail Type Multiplier × Location Factor
Step 2 — Base Construction Cost:
Base Cost = Adjusted Rate × Square Footage
Step 3 — MEP Delta (scope above base rate):
MEP Delta = max(0, (HVAC + Plumbing + Electrical costs) − (Base Rate × 30% × Sq Ft))
The base construction rate already includes approximately 30% for standard MEP systems. The delta captures only the additional cost when the selected scope exceeds that baseline.
Step 4 — Hard Cost Subtotal:
Hard Costs = Base Cost + MEP Delta + Storefront Cost
Step 5 — Soft Costs (12% of Hard Costs):
Soft Costs = Hard Costs × 0.12 — covers architecture, engineering, permit fees, and project management.
Step 6 — Contingency (10%):
Contingency = (Hard Costs + Soft Costs) × 0.10
Step 7 — Total Project Cost:
Total = Hard Costs + Soft Costs + Contingency + FF&E
Step 8 — Out-of-Pocket:
Out-of-Pocket = max(0, Total Project Cost − TI Allowance)
Assumptions & References
- Base finish rates are derived from industry benchmarks: Basic $60–$80/sq ft, Standard $80–$120/sq ft, Premium $120–$200/sq ft, Luxury $200–$350/sq ft (RSMeans, CBRE, JLL retail build-out surveys, 2023–2024).
- Retail type multipliers reflect the relative complexity of MEP and specialty systems: restaurants (+35%), medical offices (+25%), grocery (+20%), salons (+10%), gyms (+8%), general retail (baseline).
- Condition adjustments: Cold dark shell adds ~15% for MEP rough-in; gut renovation adds ~12% for demolition and disposal; second-generation space may save ~5% from reusable improvements.
- MEP allocation: Standard base rates assume ~30% of cost is MEP (mechanical, electrical, plumbing). Scope selections above this baseline generate an incremental cost delta.
- HVAC costs: Reuse existing ~$4/sq ft, partial replacement ~$12/sq ft, full new system ~$22/sq ft (ASHRAE, contractor benchmarks).
- Soft costs (architecture, permits, engineering) are estimated at 12% of hard costs, consistent with industry norms for retail projects under 10,000 sq ft.
- Contingency of 10% is recommended for projects in design development phase; increase to 15–20% for early-stage budgeting.
- Location factors are approximate regional cost indices based on ENR Construction Cost Index and RSMeans City Cost Data.
- TI allowances from landlords typically range from $20–$80/sq ft depending on market, lease term, and tenant creditworthiness (CBRE, Cushman & Wakefield leasing data).
