Louisiana CRE deals run under a civil law system that most buyers from common law states aren't ready for. Notarial acts, mineral servitudes, and a parish-level documentary transaction tax add steps that aren't in any standard checklist. This guide covers every check before you close in 2026.
Louisiana is one of the few US states that operates under a civil law system derived from French and Spanish legal codes. That matters the moment you sign a purchase agreement.
Title transfers through a notarial Act of Sale, executed before a Louisiana notary. The deed form used in other states won't work here.
Mineral rights in Louisiana are treated as a separate estate. They can be severed from the surface and held by a third party for up to 10 years under a mineral servitude - but active servitudes run with the land.

Where Louisiana property deals actually go wrong
Not every check carries the same weight. The table below sorts risks by impact on deal execution.
| Area | Documents to pull | Louisiana red flag | Matters most for | Tier | |
|---|---|---|---|---|---|
| Title and ownership | Title and ownership | Notarial Act of Sale, title commitment, 30-year chain-of-title, Clerk of Court search | Louisiana requires a notarial Act of Sale; a standard deed from another state is void | All buyers | Dealbreaker |
| Mineral servitudes | Mineral servitudes | Mineral servitude search, 10-year prescriptive period records, oil and gas lease abstracts | Active mineral servitudes in south Louisiana restrict surface use and run with the land | All buyers, development | Dealbreaker |
| Zoning and land use | Zoning and land use | Parish zoning certificate, variance history, conditional use permit records | Unincorporated Louisiana parishes lack zoning; use restrictions come from deed covenants only | Development, repositioning | Dealbreaker |
| Environmental | Environmental | Phase I ESA, DEQ database search, UST records, wetlands delineation report | Louisiana petrochemical corridor and wetlands create contamination risk on many CRE parcels | Industrial, coastal, vacant land | Dealbreaker |
| Leases and tenancies | Leases and tenancies | All leases, amendments, rent roll, estoppels, Louisiana civil code lease terms | Louisiana leases can include tacit reconduction; month-to-month rollover binds the new owner | Income-producing assets | Price-adjuster |
| Building and physical condition | Building and physical condition | Property Condition Assessment, building permit history, certificate of occupancy | Louisiana subsidence and expansive clay soils damage foundations on older New Orleans stock | All asset types | Price-adjuster |
| Service charge and costs | Service charge and costs | 3y operating statements, Louisiana property tax bills, CAM reconciliations, millage rates | Louisiana millage rates vary sharply by parish; Orleans and Jefferson levy higher commercial rates | Income-producing assets | Price-adjuster |
| Documentary transaction tax | Documentary transaction tax | Parish documentary transaction tax receipt, Clerk of Court recording fee | Tax rate and applicability varies by parish; out-of-state buyers often miss it entirely | All deals in applicable parishes | Price-adjuster |
| Insurance and valuation | Insurance and valuation | Current policies, loss run history, FEMA flood zone certificate, wind and hail coverage | Louisiana coastal and river floodplains affect most commercial parcels; flood insurance is costly | All asset types | Standard check |
| Utilities and access | Utilities and access | Utility connection records, DOTD access permits, right-of-way records | DOTD controls state highway access; coastal and rural parcels need separate access permits | Retail, logistics, industrial | Standard check |

Start free 14-day trialThe full Louisiana property due diligence checklist
Title and ownership
- Confirm title transfers via a notarial Act of Sale executed before a Louisiana notary
- Order a 30-year chain-of-title search from the Clerk of Court in the relevant parish
- Search for all recorded liens, judgments, mortgages, and encumbrances at the parish level
- Confirm whether a mineral servitude is active; run a separate mineral abstract if needed
- Check for any open mechanic's lien claims against recent construction at the parcel
- Verify the parcel description matches the Act of Sale, survey, and tax assessment records
Mineral servitudes
- Search the Clerk of Court for active mineral servitudes on the parcel
- Confirm the 10-year prescriptive period: unused servitudes prescribe under Louisiana law
- Abstract any active oil and gas leases; they run with the land and restrict surface use
- Confirm whether mineral rights were reserved by a prior seller in the chain of title
- For south Louisiana parcels: check for salt dome and subsurface extraction activity nearby
Zoning and land use
- Confirm current zoning from the parish planning department in writing
- For unincorporated parish parcels: zoning may not exist - check deed covenants and restrictions
- Pull the full variance and conditional use permit history from the local zoning board
- Verify all certificates of occupancy for buildings and improvements are current
- Confirm no open code violations or stop-work orders at the local building department
- For Orleans Parish parcels: check Historic District Commission restrictions before committing
Environmental
- Commission a Phase I ESA per ASTM E1527-21; petrochemical corridor parcels need extra scrutiny
- Search the Louisiana DEQ public database for releases, cleanups, and UST records
- Order a wetlands delineation report; Louisiana coastal and riparian parcels often include wetlands
- Run a UST search for all former gas station, dry-cleaning, and industrial parcels
- Confirm FEMA flood zone status; most Louisiana commercial parcels fall in AE or VE flood zones
- Budget Phase II at $10,000-$30,000 if recognized environmental conditions appear in Phase I
See how environmental due diligence works for how to scope this track alongside legal and financial review.
Leases and tenancies
- Collect all leases, amendments, and sublease consents before diligence opens
- Flag any Louisiana tacit reconduction clauses; leases can roll month-to-month and bind buyers
- Cross-reference the rent roll against 3 months of actual bank receipts from the seller
- Confirm estoppel certificates are deliverable before the scheduled closing date
- Identify any month-to-month occupancies or undocumented tenants on the property
- Check for tenant purchase options or rights of first refusal embedded in lease terms
Load all lease files into Ellty so your attorney and advisors can review without open folder access.
Building and physical condition
- Commission a Property Condition Assessment; check subsidence and clay soil risk in New Orleans
- Pull the full building permit history from the local building department
- Check for unpermitted additions common in older New Orleans and Baton Rouge commercial stock
- Confirm ADA compliance documentation for all commercial spaces on the property
- Inspect foundations closely; Louisiana expansive soils cause differential settlement on many sites
- Verify roof condition; Louisiana hurricane exposure accelerates wear on older commercial stock
Service charge and operating costs
- Pull 3 years of operating statements and reconcile against actual property tax bills
- Check the parish millage rate; Orleans and Jefferson levy higher commercial rates than rural parishes
- Audit CAM pass-throughs against lease terms for all multi-tenant assets
- Check for pending parish or city infrastructure special assessments on the parcel
Documentary transaction tax and recording
- Confirm whether the parish levies a documentary transaction tax on the transaction
- Calculate the applicable rate; Orleans Parish charges $325 per $100,000 of consideration
- Pay the documentary transaction tax before presenting the Act of Sale for recording
- Note: not all Louisiana parishes levy this tax - confirm with the local Clerk of Court
Insurance and valuation
- Pull current insurance policies and a 3-year loss run history from the seller
- Check FEMA flood zone status; most Louisiana CRE requires separate flood coverage
- Verify wind and named storm coverage is in place; standard policies exclude hurricane damage
- Order an independent appraisal scoped to the intended use and lender requirements
Utilities and access
- Verify all utility connections are active and legally transferable at closing
- Check DOTD records for any state highway access permit requirements on the parcel
- Confirm legal road access via recorded servitude or dedicated public right of way
- Verify stormwater drainage compliance with parish or city drainage permits
Seller KYC and AML
- Confirm seller identity matches the Clerk of Court Act of Sale record exactly
- For LLC or corporate sellers: confirm good standing with the Louisiana Secretary of State
- Run bankruptcy, federal tax lien, and judgment lien searches before committing to close
- Confirm entity authority to sell; Louisiana LLCs require manager or member authorization

How property due diligence in Louisiana works
Step 1 - Title search
Start the title search immediately after the purchase agreement is signed. Louisiana is a civil law state; title works differently from common law recording systems.
Commission a 30-year chain-of-title at the Clerk of Court. Confirm the Act of Sale chain is intact and no mineral servitudes are active on the parcel before proceeding.
Step 2 - Survey and inspection
Order an ALTA/NSPS survey alongside the title search. Confirm the parcel description, legal boundaries, and all servitude locations match the Act of Sale exactly.
Commission the Property Condition Assessment in parallel. Louisiana subsidence and clay soils mean foundation condition needs close review on any New Orleans or Baton Rouge site.
Step 3 - Leases and income review
Pull all leases and flag any tacit reconduction clauses first. Louisiana law allows leases to roll month-to-month automatically if neither party terminates in time.
Check the legal due diligence guide for how to structure a parallel-track review. Adapt the standard request list for Louisiana civil code lease terms and parish tax items.
Step 4 - Environmental review
Run the Phase I ESA and Louisiana DEQ database search in parallel. Petrochemical plants, refineries, and industrial sites are common neighbors to commercial parcels in south Louisiana.
Load DEQ search results and Phase I findings into Ellty so lenders and advisors can access them without open-folder permissions. Track who reviewed which file and when.
Step 5 - Closing and registration
Louisiana requires the Act of Sale to be executed before a notary and recorded at the Clerk of Court. No other state form substitutes for this requirement.
Confirm the Louisiana Secretary of State good-standing certificate for any LLC or corporate seller is current before closing day. Out-of-state buyers regularly miss this step.
How to set up your Louisiana data room in Ellty.
Load Louisiana property files before advisors arrive. Give each one a scoped link on day one.
- 1.Create a data room and upload the property filesDrop title docs, leases, DEQ search results, and mineral servitude records into Ellty. Each folder maps to a diligence area.
- 2.Give each advisor a scoped, secure linkYour title attorney sees title files only. The ESA consultant sees environmental files only. Ellty enforces the scope.
- 3.Track who reviews which documentsSee which files each advisor opened and when. Spot delays before they slow the Louisiana close.
What makes due diligence in Louisiana different
Louisiana's civil law system is the first thing that catches out-of-state buyers. The Act of Sale must be executed before a Louisiana notary. Buyers who use out-of-state closing attorneys or standard deed forms void the transfer.
Mineral servitudes are the second trap. South Louisiana has a long petrochemical and oil extraction history. A buyer who skips the mineral abstract can close on land with active drilling rights they never factored into the price.
Flood and wind exposure is a cost most buyers underestimate. Nearly all Louisiana commercial parcels fall inside FEMA flood zones. Flood insurance can run $20,000-$80,000 per year on mid-market assets near the coast.
In Louisiana, a transfer of immovable property must be made by authentic act or by act under private signature duly acknowledged. An instrument not executed before a Louisiana notary does not transfer title under Louisiana Civil Code Article 1839.
Timeline and cost in Louisiana
Week 1-2 covers kickoff: Clerk of Court title search, mineral servitude abstract if needed, ALTA survey engagement, Phase I ESA, and Louisiana DEQ database search. Budget $3,500-$8,000 for this phase.
Load all files into Ellty on day one and give each advisor a trackable scoped link. That removes weeks of email follow-up from a standard Louisiana diligence process.
Weeks 2-4 cover deep review: Phase I ESA delivery, Property Condition Assessment, lease abstraction, mineral servitude review, millage rate check, and FEMA flood zone confirmation.
Cost for weeks 2-4 runs $5,000-$18,000 depending on Phase I scope and asset complexity. Phase II ESA adds $10,000-$30,000 if recognized environmental conditions surface; budget it early.
Weeks 4-6 handle resolution: Phase II if needed, title exception negotiations, documentary transaction tax, and closing before a Louisiana notary.
Orleans Parish documentary transaction tax runs $325 per $100,000 of consideration. Buy-side legal fees typically run $3,000-$8,000 for a standard Louisiana commercial close. Notary fees add $500-$2,500 depending on complexity. See real estate due diligence done right to model how Louisiana-specific costs fit your full deal budget.

Start free 14-day trialCommon questions about property due diligence in Louisiana
- Louisiana operates under a civil law system. Title to immovable property must transfer by authentic act before a Louisiana notary. A standard warranty deed from another state does not transfer title.
- A mineral servitude is a real right allowing a third party to extract minerals from your land. Active servitudes run with the property and restrict surface development without prescribing for 10 years.
- Some parishes levy a documentary transaction tax. Orleans Parish charges $325 per $100,000. Not all parishes apply it - confirm the applicable rate with the local Clerk of Court before closing.
- Petrochemical contamination, UST sites, and wetlands delineation issues are the main risks. Search the Louisiana DEQ public database and commission a Phase I ESA on every deal.
- Standard Louisiana deals take 45-65 days. Civil law title issues, DEQ environmental findings, or mineral servitude searches regularly push timelines past 90 days.
- Yes. Louisiana's civil law system requires a Louisiana-licensed notary for the Act of Sale. Out-of-state closing attorneys cannot execute a valid transfer of Louisiana immovable property.
