The General Phases of a Commercial Remodel

Phase 1: Planning and Design

The foundation of every successful commercial remodel lies in the planning and design stage. This phase typically sets the tone for how long the overall project will take. Here’s what to expect during this initial step:

1. Assessment of Goals and Needs

Timeline: 1–2 weeks
Sit down with a commercial construction manager to figure out the remodel’s purpose. Are you optimizing your layout, refreshing the space for branding purposes, or integrating new infrastructure?

2. Concept and Design Development

Timeline: 4–8 weeks
Designers and architects will turn your ideas into comprehensive floor plans and renderings. If you’re working with an experienced team, they’ll also ensure the design aligns with local building codes and ADA guidelines.

3. Estimation of Costs

Timeline: 1–2 weeks
Pro Tip: Collaborating closely with your design team saves time by identifying issues early and reducing the number of costly change orders down the line.
You’ll need preliminary cost evaluations for construction, materials, and commercial renovation costs. This step ensures your design aligns with the project’s budget parameters.

Phase 2: Permitting and Approvals

Before construction can begin, your project needs to receive the necessary permits and approvals. This phase can be unpredictable depending on your location and the complexity of your project.

1. Permit Application Submission

Timeline: 2–4 weeks (may vary based on local regulations)
Your contractor or architect will submit the required documentation to local authorities, which may include engineering drawings and detailed plans.

2. Review and Approval Window

Timeline: 3–8 weeks
Depending on how busy your local building department is, the waiting period for approvals could range from a few weeks to months.

3. Addressing Municipal Feedback

Timeline: 1–2 weeks
Potential Delays: Materials may need to comply with ADA standards, and additional approvals may be required for zoning or safety compliance. To reduce delays, ensure thorough documentation.
If city officials request revisions or additional information, time will be added to this step.

Phase 3: Construction

Once permits are secured, the most visible phase begins. Construction is where timelines can vary drastically, depending on the scope of the remodel and potential challenges.

1. Site Preparation and Demolition

Timeline: 1–4 weeks
Structural elements or interior fixtures that need to be removed or relocated will be handled during this stage to prepare the site for construction.

2. Structural Work and Framing

Timeline: 3–6 weeks
This involves tasks like drywall construction, window installation, and any changes to the building’s structural layout.

3. Mechanical, Electrical, and Plumbing (MEP)

Timeline: 4–8 weeks
Upgrading or installing HVAC systems, electrical wiring, and plumbing is a critical step in every remodel.

4. Interior Finishes and Fixtures

Timeline: 4–8 weeks
Watch Out For: Delays caused by material shortages or weather conditions may occur during exterior construction tasks or installations. Proactively procure materials in advance to mitigate risks.
Tasks like flooring, painting, and installing lighting fixtures fall under this category. This stage also includes placing furniture and any decorative elements.

Phase 4: Final Inspections and Handover

Before your newly remodeled space is ready for use, the project goes through a critical final phase. Here are the general steps to that phase:

1. Inspection Walkthroughs

Timeline: 1–2 weeks
Local authorities will perform inspections to certify that the remodel meets safety, health, and construction codes.

2. Addressing Outstanding Punch List Items

Timeline: 1–2 weeks
If inspectors identify any issues or non-compliance, additional adjustments may need to be made.

3. Handover and Occupancy Certificate

Timeline: 1–2 weeks
Once the remodel passes all inspections, you’ll receive a certificate of occupancy, signaling project completion.
Remember to allocate time for final clean-up and preparing the space for reopening.

Tackling Common Delays in Commercial Remodels

Though estimating a perfect commercial remodel timeline is difficult, knowing the common obstacles helps you plan around potential delays. These include:

Weather Conditions: Exterior work, such as roofing or landscaping, may be postponed due to poor weather.
Material Delays: Supply chain disruptions could impact timelines, especially for custom pieces.
Change Orders: Introducing design modifications after construction has started can push deadlines back significantly.
Inspection Issues: Failing an initial inspection may result in reworking specific sections and scheduling another inspection.
Subcontractor Scheduling: Misalignment between the availability of plumbing, electrical, and other specialists can lead to downtime.

Key Considerations for Setting a Realistic Budget

Your commercial remodel’s budget will correlate with the scale and quality of the project. Here’s a rough guide to help you estimate costs:

Small Renovations (Office refresh): $5,000–$20,000
Medium-Sized Projects (Retail/Office remodel): $20,000–$100,000
Large-Scale Remodels (Full building renovations): $100,000+
High-End Finishes: Expect significant cost increases for custom designs or high-end materials.

When finalizing your budget, allocate 10%–15% of the estimated costs for unforeseen emergencies and unexpected construction costs.

Take On Your Remodel with Confidence

Every commercial remodel involves multiple moving parts, which is why understanding the step-by-step timeline is essential. From careful planning to final handover, each stage requires attention to detail, proper management, and the flexibility to adapt to unexpected challenges.
