How to Create a Commercial Real Estate Development Gantt Chart

Plan a commercial real estate development project with a Gantt chart. Track site acquisition, entitlements, design, construction, and lease-up in one visual timeline.

How to Create a Commercial Real Estate Development Gantt Chart

The Problem: CRE Development Has Too Many Parallel Workstreams

Commercial real estate development projects—office buildings, retail centers, industrial parks, mixed-use towers—involve dozens of interdependent workstreams running simultaneously over 2-7 years. A developer managing a single $50M office project coordinates architects, civil engineers, geotechnical consultants, attorneys, lenders, city planners, general contractors, leasing brokers, and future tenants. Without a shared timeline, critical path items fall through the cracks.

The most expensive mistakes in CRE development are schedule mistakes. A 3-month delay in entitlements pushes your construction loan draw, increases carry costs, and risks losing an anchor tenant whose lease required occupancy by a specific date. Developers who track their schedule informally—in spreadsheets or email threads—consistently underestimate the time required for permitting and fail to protect their contingency periods.

A commercial real estate development Gantt chart maps every phase from site control through stabilized occupancy, makes the critical path visible, and lets your whole team—from equity partners to the GC—see where the project stands. gantt-chart.io lets CRE developers build and share this schedule without the complexity of enterprise project management software.

Prerequisites

Before building your commercial real estate development Gantt chart:

  • Project type: Office, retail, industrial, mixed-use, hospitality—each has different entitlement and construction timelines
  • Site status: Under LOI, under contract, or already owned
  • Zoning: Current zoning vs. required zoning; whether a rezoning or variance is needed
  • Entitlement jurisdiction: City, county, or state permitting authority and their published review timelines
  • Financing structure: Construction loan closing timeline, equity funding schedule, any mezzanine debt
  • Design team: Architect and engineer contracts signed or in negotiation
  • Anchor tenant status: Any pre-leasing commitments that create hard delivery deadlines
  • Construction market: GC procurement strategy (negotiated vs. bid) and current lead times for steel, concrete, curtainwall

Step-by-Step Instructions

Step 1: Set Up the Development Timeline

  1. Open gantt-chart.io
  2. Title it "[Property Name] — [Type] — [City] — Target Delivery [Quarter/Year]"
  3. Set the view to cover the full development period: typically 3-5 years for a ground-up commercial project
  4. Use Month view for pre-construction and entitlement phases; Week view for construction
  5. Add Certificate of Occupancy as the hard red milestone. Add Construction Loan Closing and Lease Execution — Anchor Tenant as orange milestones.

Step 2: Site Acquisition Track

  1. Create a task group: Site Acquisition
  2. Add:
  • LOI negotiation and execution — 2-4 weeks
  • Purchase and sale agreement negotiation — 3-6 weeks
  • Feasibility period / due diligence — 30-60 days; hard deadline per PSA
  • Title review and curative work — runs concurrent with feasibility
  • Environmental Phase I / Phase II — Phase I takes 3-4 weeks; Phase II if needed adds 6-10 weeks
  • Survey and boundary review — 2-3 weeks
  • Geotechnical investigation — 3-5 weeks
  • Hard deposit goes non-refundable — milestone
  • Site closing — milestone
  1. Flag the feasibility period end as a go/no-go decision point.

Step 3: Entitlements and Permitting Track

  1. Create a task group: Entitlements & Permitting
  2. Add:
  • Pre-application meeting with planning department — 2-4 weeks to schedule
  • Rezoning application submittal — if required; 3-9 months for approval
  • Site plan / design review application — 4-12 weeks for initial review cycle
  • Traffic impact study — 6-10 weeks
  • Environmental review (CEQA/NEPA if applicable) — 3-18 months depending on complexity
  • Utility coordination (water, sewer, power, gas) — 3-6 months for service agreements
  • Building permit application submittal — after design is complete
  • Building permit issued — milestone
  1. Entitlements are almost always the longest phase. Add a 2-month buffer after any city review period.

Step 4: Design and Engineering Track

  1. Create a task group: Design & Engineering
  2. Add:
  • Schematic design — 6-10 weeks
  • Design development — 8-12 weeks
  • Construction documents — 50% CD — milestone
  • Construction documents — 100% CD — milestone
  • GC pricing / bid period — 4-8 weeks
  • Value engineering — 2-4 weeks
  • Construction documents — permit set — milestone

Step 5: Financing Track

  1. Create a task group: Financing
  2. Add:
  • Construction loan term sheet — 2-4 weeks
  • Lender due diligence period — 30-60 days
  • Appraisal — 4-6 weeks
  • Construction loan closing — milestone
  • Equity funding confirmation — milestone
  • First draw request — milestone; typically at construction start

Step 6: Construction Track

  1. Create a task group: Construction
  2. Add:
  • Site work and demolition — 4-12 weeks
  • Foundation and underground utilities — 6-16 weeks
  • Structural frame — varies widely; 3-12 months for multi-story
  • Skin / envelope closure — 2-6 months
  • MEP rough-in — 3-6 months
  • Interior finishes — core and shell — 2-4 months
  • Tenant improvement construction — 2-4 months (may overlap)
  • Substantial completion — milestone
  • Certificate of Occupancy — milestone

Key Milestones

MilestoneTypical Timing

Feasibility period expiresMonth 2-3
Site closingMonth 3-5
Building permit issuedMonth 12-24
Construction loan closesMonth 14-26
Construction startMonth 15-28
Structural topping outMonth 24-36
Substantial completionMonth 36-54
Certificate of OccupancyMonth 38-56
Stabilized occupancy (90%+ leased)Month 44-66

Common Mistakes

  • Assuming entitlements will take the published timeline: City review clocks are rarely accurate. Budget 50-100% more time than the official review period suggests, especially for projects requiring discretionary approval.
  • Starting design before site control is secured: Significant design fees spent before site closing are at risk if the deal falls apart during feasibility. Time the major design investment to begin after the deposit goes hard.
  • Not tracking the construction loan draw schedule: Lenders have specific documentation requirements for each draw. Missing a draw deadline can halt construction and trigger default provisions.
  • Omitting tenant improvement timelines: TI construction for each tenant is a separate project within your project. Failing to track TI schedules means tenants move in later than their lease requires, creating liability.
  • No contingency buffer before the anchor tenant delivery date: Add a minimum 60-day buffer between substantial completion and any contractually obligated delivery date to your anchor tenant.
