Frequently Asked Questions

Commercial Construction Process

How long do commercial projects take?

The timeline depends on project size and complexity. Small tenant improvements take 4-8 weeks. New construction or major remodels take 3-6 months. We provide detailed schedules based on your specific project.

Can our business stay open during construction?

Sometimes yes, depending on scope. We schedule work during off-hours when possible, phase projects to maintain operations, and coordinate with you to minimize business disruption.

Do you handle all permits and inspections?

Yes, we manage all commercial permits, coordinate inspections, ensure code compliance, and handle building department requirements. Commercial projects have more stringent requirements than residential.

What's your experience with commercial codes?

We’re familiar with commercial building codes, ADA requirements, fire safety regulations, and local jurisdiction requirements. Our projects pass inspections because we build to code from the start.

Planning & Design

Do you work with architects on commercial projects?

Yes, we coordinate with architects and engineers regularly. We provide input during design on constructability and costs. Good collaboration between design and construction teams produces better results.

Can you help with space planning?

We provide input on layouts that work functionally and meet code requirements. For detailed space planning, we recommend working with architects or commercial designers who specialize in your business type.

What about ADA compliance?

All commercial spaces must meet ADA requirements. We ensure proper door widths, accessible restrooms, ramps where needed, appropriate signage, and parking compliance. ADA requirements are built into our commercial work.

How do you minimize business disruption?

We schedule noisy work during off-hours when possible, maintain access to critical areas, coordinate work in phases, communicate schedules clearly, and work efficiently to complete projects quickly.

Restaurant & Retail Specific

What makes restaurant construction different?

Restaurants require commercial kitchen equipment hookups, proper ventilation and hood systems, grease traps and interceptors, health department approval, adequate electrical for equipment, and specific finishes that meet health codes.

Do you handle health department requirements?

Yes, we build to health department standards, coordinate required inspections, install proper sinks and sanitation equipment, and ensure finishes meet requirements. We know what health departments require.

What about retail storefronts?

Retail storefronts need attractive entrances, proper glass and doors, adequate lighting, security considerations, and visibility. We build storefronts that attract customers while meeting code requirements.

Can you work around existing inventory?

We protect inventory during construction, work in phases to minimize impact, coordinate with your operations, and schedule work to avoid your busy periods when possible.

Tenant Improvements & Remodeling

What are tenant improvements?

Tenant improvements modify existing commercial space for new tenants—adding walls, updating finishes, improving layouts, upgrading systems, and customizing spaces to suit specific business needs.

Do you coordinate with landlords?

Yes, we work with property owners on approvals, coordinate with building management, ensure work meets lease requirements, and handle communication between tenants and landlords.

Can you update outdated commercial spaces?

We modernize older commercial spaces with updated finishes, improved lighting, better HVAC, modernized electrical, and layouts that work for current business needs.

What about working in occupied buildings?

We minimize disruption to other tenants, maintain building access, control dust and noise, work during appropriate hours, and coordinate with building management throughout the project.

Budget & Timeline

How much do commercial projects cost?

Commercial construction costs vary widely by project type, size, and finishes. Tenant improvements cost less than ground-up construction. We provide detailed estimates after understanding your requirements.

What affects commercial construction costs?

Project size, finish quality, site conditions, code requirements, and timeline expectations affect costs. Commercial projects have higher standards than residential, which affects pricing.

Can projects be phased to manage costs?

Sometimes yes. We can phase work to spread costs over time or maintain partial operations. Phasing extends overall timelines but can help with cash flow management.

Do you work with commercial lenders?

Yes, we provide documentation required by commercial lenders, work within their draw schedules, and coordinate with lenders throughout construction.

Quality & Compliance

How do you ensure commercial quality standards?

We use commercial-grade materials, follow commercial building codes, install systems properly, conduct quality inspections, and ensure work meets higher standards required for commercial spaces.

What warranty comes with commercial work?

We warranty our workmanship. Equipment and materials come with manufacturer warranties. We address issues during warranty periods and remain available after project completion.

Do you carry proper insurance for commercial work?

Yes, we carry commercial general liability insurance, workers compensation, and required bonds. We provide certificates of insurance as needed for projects.
