Renovating a laboratory is far more complex than renovating an office or commercial space. Labs have specialized utility infrastructure, strict ventilation requirements, chemical-resistant materials, and regulatory standards that must be followed precisely.
This guide covers the complete lab renovation process — from initial assessment through design, construction, and commissioning — so you can plan your project with confidence.
When to Renovate vs Build New
Renovation makes sense when:
- The building structure is sound and the location works
- The existing utility infrastructure (HVAC, plumbing, electrical) can be upgraded cost-effectively
- Budget is limited — renovations typically cost 30-60% less than new construction
- Timeline is shorter than building new
- Regulatory or institutional constraints require staying in the current location
Build new when the existing building cannot support the required ventilation, structural loads, or utility capacity, or when the renovation cost approaches 70-80% of new construction cost.
Phase 1: Assessment and Programming
Before design begins, thoroughly assess the existing space and define requirements:
Existing Conditions Assessment
- HVAC capacity — can the existing air handling system support the required fume hood count and air changes? Fume hoods are the largest HVAC load in any lab.
- Electrical capacity — is there enough panel capacity for instruments, hoods, and additional circuits?
- Plumbing — can gas, water, waste, and DI water lines be extended to new locations?
- Structural — can the floor support heavy equipment? Upper floors may need structural analysis for items like NMR instruments or vibration-sensitive balances.
- Hazardous materials — older buildings may contain asbestos, lead paint, or PCBs that require abatement before construction.
Programming (Defining Requirements)
- Number of researchers/technicians and their work types
- Equipment list with utility requirements (power, water, gas, ventilation)
- Fume hood count and types needed
- Storage requirements — chemicals, supplies, samples, waste
- Specialty spaces — cold rooms, dark rooms, tissue culture, instrument rooms
- Adjacency requirements — which spaces need to be near each other
- Future flexibility — will research programs change?
Phase 2: Design
Lab Layout Design
The layout determines workflow efficiency and safety. Key considerations:
- Open vs enclosed labs — modern lab design trends toward open plans with shared equipment zones, balanced with enclosed spaces for sensitive work
- Bench configurations — island benches, wall benches, or peninsula benches depending on space and workflow
- Fume hood placement — away from doors, high-traffic areas, and HVAC diffusers to prevent airflow disruption
- Emergency access — two exits from every lab, clear paths to eyewash stations and safety showers
- ADA compliance — accessible workstations, aisle widths, and emergency equipment at every design stage
Furniture Selection
Choose furniture early because it affects utility locations and space planning:
- Casework — fixed for stable lab programs, modular for flexibility. Steel, wood, or phenolic based on the environment.
- Work surfaces — epoxy resin for chemistry, phenolic for biology, stainless steel for healthcare, laminate for light-duty.
- Shelving — wire shelving for supply storage, high-density mobile shelving for sample archives.
- Specialty furniture — healthcare furniture for clinical labs, clean bench stations for sensitive work.
Mechanical, Electrical, and Plumbing (MEP) Design
MEP design is the most expensive and complex part of any lab renovation:
- HVAC — lab ventilation requires 6-12 air changes per hour (ACH) for general labs, more for high-hazard work. Each fume hood adds 800-1,500 CFM of exhaust capacity needed.
- Electrical — typical lab requires 15-25 watts per square foot, 3-4x a standard office. Emergency power for critical instruments.
- Plumbing — lab-grade piping for acid waste, DI water, specialty gases, vacuum, compressed air. Acid-resistant drain materials (polypropylene or glass-lined).
Phase 3: Budgeting
Typical Lab Renovation Costs
| Component | Cost Range per SF | % of Total |
|---|---|---|
| Construction (general) | $80-$200 | 35-45% |
| HVAC/mechanical | $60-$150 | 25-35% |
| Lab furniture and equipment | $40-$100 | 15-25% |
| Electrical and plumbing | $30-$80 | 10-15% |
| Design and engineering | $15-$40 | 5-10% |
Total renovation costs typically range from $200 to $500+ per square foot depending on the lab type, complexity, and region. Wet chemistry labs and clean rooms are at the high end. Dry labs and computational spaces are at the low end.
Budget Tips
- Include a 10-15% contingency for unknowns (hidden conditions are common in renovations)
- Price furniture early — it is a major cost item and lead times can be 8-16 weeks
- VAV (variable air volume) fume hood systems cost more upfront but save significantly on energy long-term
- Modular furniture and demountable partitions cost more initially but save on future reconfigurations
Phase 4: Construction
Phasing for Occupied Buildings
If the building remains occupied during renovation, phasing is critical:
- Divide the project into zones that can be renovated sequentially
- Provide temporary lab space for displaced researchers
- Maintain fire/life safety systems throughout construction
- Control dust, vibration, and noise — active labs are sensitive to all three
- Coordinate utility shutdowns carefully to minimize disruption to other labs
Common Construction Challenges
- Hidden conditions — older buildings often reveal unexpected plumbing, electrical, or structural issues once walls are opened
- Asbestos and lead — abatement adds time and cost
- Utility capacity — discovering that the main electrical panel or air handling unit cannot support the new design
- Lead times — fume hoods, casework, and specialty items may have 8-20 week lead times. Order early.
Phase 5: Commissioning and Move-In
Commissioning Checklist
- Fume hood face velocity testing (ANSI/ASHRAE 110 method)
- Room air change rate verification
- Emergency eyewash and shower testing
- Gas and vacuum line pressure testing
- Electrical circuit verification and labeling
- Fire alarm and suppression system testing
- Safety equipment inspection (fire extinguishers, spill kits, first aid)
Move-In Planning
- Chemical inventory and relocation plan (DOT compliance for transport)
- Equipment calibration after relocation
- Staff orientation to new spaces, emergency equipment, and evacuation routes
- Punch list completion before full occupancy

Frequently Asked Questions
How long does a lab renovation take?
Small renovations (one or two rooms) take 3-6 months from design through move-in. Large renovations (full floors or buildings) take 12-24 months. The design phase typically takes 2-4 months and furniture lead times add 8-16 weeks.
Can we stay in the building during renovation?
Yes, with proper phasing. The project is divided into zones, and researchers move temporarily while their zone is renovated. This adds time to the overall schedule but avoids the cost and disruption of a complete relocation.
What is the biggest cost driver in lab renovation?
HVAC is almost always the largest single cost. Adding or modifying fume hoods requires additional exhaust capacity, supply air make-up, and often ductwork changes. Budget 25-35% of total project cost for mechanical systems.
How do I reduce lab renovation costs?
Reuse existing HVAC infrastructure where possible. Choose modular furniture that does not require custom millwork. Plan utility runs efficiently to minimize piping and ductwork. Get furniture quotes early to avoid budget surprises.
Do I need a lab design specialist or can my architect handle it?
General architects can design labs but often miss critical details about chemical resistance, ventilation requirements, and utility integration. A lab design specialist or a furniture supplier with lab design experience (like Labs USA) ensures the design meets scientific requirements. Many projects use a general architect plus a lab planning consultant.
