Due Diligence before Commercial Real Estate Deals
Due Diligence for Small Businesses Opening Their First Retail Space
Opening your first retail location is an exciting milestone — but it also comes with complex decisions and potential pitfalls that can derail your timeline and budget if not properly planned. Before you sign a lease, hire a contractor, or order your signage, it’s crucial to do your due diligence.
This guide outlines what small business owners need to know before building out a new retail space, and who to bring onto the team to make the process smoother.
🧠 What Is Due Diligence in Retail Real Estate?
Due diligence is the process of researching and verifying all critical factors about a potential space before you commit. This includes assessing zoning, compliance requirements, building conditions, design feasibility, costs, and timelines.
Skipping this step often leads to unforeseen expenses, delays, or even needing to abandon the space after signing a lease.
🧱 Key Areas to Investigate
1. Zoning & Use Compatibility
Is your business type (retail, salon, daycare, etc.) allowed in that location?
Are there use restrictions in the lease or the zoning code?
Tip: Don’t assume it’s okay just because a similar business was there before.
2. Space Condition & Infrastructure
Is the HVAC functional? Are electrical and plumbing systems adequate?
Will the space need accessibility upgrades (ADA compliance)?
Is there enough ceiling height, ventilation, power, and egress?
Pitfall: Assuming the space is “move-in ready” — it rarely is.
3. Permitting & Code Requirements
Will the build-out require a building permit? Most do.
Will your plans trigger fire, ADA, or health department reviews?
Tip: Permits can take weeks (or months). Start early.
4. Landlord Work vs. Tenant Work
What will the landlord provide (demo, sprinklers, bathrooms)?
What are you (the tenant) responsible for?
Pitfall: Many tenants overestimate what’s included in the “white box.”
5. Timeline Feasibility
Can you realistically open in 2–3 months?
How long will design, permits, and construction take?
Reality: Fit-outs typically take 3–6 months, start to finish.

Final Thoughts
Opening a retail space is more than just designing a beautiful interior — it’s a construction and compliance project. Taking time to do your due diligence, and surrounding yourself with the right experts, can save you from costly delays and rework.
Treat your first space like a real estate project, not just a business milestone. It’ll set the tone for every location you open after that.
