A useful commercial renovation budget has to account for far more than finishes. Occupancy, building systems, accessibility, plan review, long-lead equipment, and the condition of the existing space all shape the final investment and opening date.
The fastest projects are usually the ones that resolve use, code, equipment, and landlord requirements before crews mobilize. The opening date should be built from real dependencies, not a desired ribbon-cutting date.
A low construction proposal is not a complete budget when design, permits, utility upgrades, furniture, technology, and owner-supplied equipment are missing.
Coordinate vendor deliveries, signage, internet, security, furniture, and staff training with the construction schedule so a finished space can actually open.
Choose the closest project profile for a rough feasibility range. This tool is for initial planning and cannot replace drawings, a site walk, or a line-item proposal.
Planning range only. It excludes property acquisition, rent, financing, professional fees, loose furniture, specialty owner equipment, and conditions that have not been investigated.
Square footage matters, but use and system intensity often matter more. A quiet office and a restaurant of the same size are not comparable projects.
Office renovations typically emphasize flexible planning, acoustics, lighting, power, data, conference rooms, and employee comfort.
Private rooms, open work areas, phone rooms, and meeting spaces need deliberate sound control and circulation.
Floor boxes, dedicated circuits, data pathways, access control, and audiovisual systems should be coordinated before finishes.
Retail projects combine customer experience with durable details, merchandising flexibility, security, storage, and an efficient checkout path.
Facade work, signs, lighting, and entry conditions may involve both landlord approval and municipal review.
High-traffic flooring, wall protection, adjustable displays, stock areas, and delivery paths reduce operational headaches.
Restaurants are system-heavy renovations because cooking, ventilation, sanitation, refrigeration, grease management, and customer areas must work together.
Hoods, make-up air, gas or electric equipment, floor sinks, and fire suppression can drive the core budget.
Washable surfaces, hand sinks, restroom access, occupant load, exits, and inspections influence both layout and approvals.
Investigate these four areas before treating any early estimate as a reliable construction number.
New occupancy, equipment, partitions, or operating hours can require load calculations, distribution changes, controls, or new equipment.
Service capacity, panels, lighting controls, emergency lighting, kitchen equipment, and technology loads must be coordinated.
Restroom counts, accessible clearances, service sinks, food-service fixtures, and long drain runs can materially change scope.
Exits, travel distance, alarms, sprinklers, rated assemblies, hardware, and occupant load belong in early planning.
Allocations vary by property and business type, but organizing the budget by system makes omissions easier to see.
| Budget Category | Planning Allocation | What It Includes |
|---|---|---|
| Design, Engineering, Permits | 8%–15% | Field verification, code analysis, drawings, consultants, plan review, permits, and coordination. |
| Demolition and Base Building | 12%–20% | Selective demolition, protection, framing, ceilings, fire-rated work, and repairs to existing conditions. |
| Mechanical, Electrical, Plumbing | 25%–40% | HVAC, power, lighting, controls, plumbing, fire alarm, sprinkler modifications, and inspections. |
| Interior Finishes and Millwork | 20%–35% | Flooring, paint, tile, doors, glass, counters, cabinets, fixtures, and finish carpentry. |
| Contingency | 10%–20% | Concealed conditions, field corrections, documented scope changes, and price movement. |
Compare scope, exclusions, and responsibilities—not just bottom-line price.
A cosmetic refresh may take weeks, while a permitted tenant buildout often takes several months from investigation through turnover. Specialty uses, plan review, long-lead equipment, and base-building upgrades can extend the schedule.
Sometimes. Phasing requires safe separation, maintained exits, dust and noise control, temporary utilities, and a schedule that protects customers and employees. Phasing can add time and cost.
Not necessarily. Compare drawings, inclusions, allowances, exclusions, schedule assumptions, and who owns permit and building coordination. Missing scope commonly returns later as a change order.
