Environmental assessments, structural inspections, zoning confirmation, and a review of existing leases before you commit — here's what a thorough process actually covers.
Negotiate a due diligence period that's actually long enough
Environmental assessments and lease/financial review both take real time — a rushed due diligence period is how issues get missed, not avoided.
Assemble your team early
A commercial real estate lawyer, an environmental consultant, and a building inspector experienced with commercial property should all be lined up before your clock starts running, not after.
Work through each category systematically
Environmental, structural, zoning, leases and tenants, and financials each need their own review — treat this as five separate workstreams, not one general inspection.
Get everything in writing before you waive conditions
Verbal assurances from a seller or listing agent aren't a substitute for a written report or a confirmed answer from the City — don't waive a condition based on something you were only told.
A Phase I Environmental Site Assessment (and a Phase II if issues surface) checks for contamination risk, especially for industrial-use or older sites.
A commercial-experienced inspector should assess the roof, structure, HVAC, electrical, and life-safety systems.
Confirm your intended use is actually permitted, not just similar to what's already there.

For an income property, review every lease in full — terms, rent escalations, renewal options, and any tenant defaults or disputes.
Verify actual rent roll, operating expenses, and property tax history against what you were told, not just a summary NOI figure.
A title search and current survey confirm there are no easements, encroachments, or liens that could affect your intended use.
