Construction Defects Discovered After Buying a Commercial Property: Who Is Responsible?
Construction Defects Discovered After Buying a Commercial Property: Who Is Responsible?
In California, responsibility for construction defects discovered after buying a commercial property may fall on the seller, developer, general contractor, subcontractors, or design professionals, depending on what caused the defect and the legal duties involved. Buying the property does not automatically make you responsible for someone else’s defective work. However, your ability to recover depends on the evidence, purchase agreement, available claims, and applicable deadlines.
You purchased a commercial building expecting it to support your business or generate rental income. Then the problems began: a roof that leaks during rain, cracks spreading across warehouse flooring, or water appearing behind newly painted walls.
Now you face repair costs, tenant concerns, and a difficult question: Who should pay?
At The Naumann Law Firm, we help commercial property owners evaluate construction defect disputes. Identifying responsibility starts with understanding the building’s history, the cause of the damage, and what was represented before the sale.
What Counts as a Construction Defect in a Commercial Property?
A commercial construction defect is a deficiency in design, materials, or construction that can impair a building’s performance, safety, or intended use. A costly building problem is not necessarily a construction defect. Ordinary wear, deferred maintenance, and defective construction can produce similar symptoms.
Potential examples include:
- Roof leaks caused by improperly installed flashing or roofing assemblies.
- Water intrusion around windows, exterior walls, or doors.
- Foundation or slab damage associated with inadequate soil preparation.
- Drainage systems that direct water toward the building.
- Structural deficiencies involving framing, connections, or load-bearing components.
- Improperly installed plumbing, electrical, or mechanical systems.
For example, an aging roof that has reached the end of its useful life presents a different issue from a newer roof that leaks because critical flashing was installed incorrectly.
Our article on common examples of construction defects explains additional warning signs owners may encounter.
Who May Be Responsible for Defects Discovered After the Purchase?
More than one party may share responsibility. The seller’s conduct and the original construction work are separate issues, and both may require investigation.
The Seller
A seller may face liability for misrepresentations, actionable concealment, or breaches of promises made in the purchase agreement. California law recognizes that suppressing a fact can constitute deceit when there is a duty to disclose it or when other statements become misleading without that information.
Relevant questions include:
- Did the seller know about recurring leaks or structural concerns?
- Were prior engineering reports or repair records withheld?
- Did the seller make statements about the building’s condition that were inaccurate?
- Did the purchase agreement contain representations or warranties covering the problem?
Discovering a defect after closing does not, by itself, establish seller liability. The seller’s knowledge, disclosure obligations, statements, and contract terms must be evaluated.
The Developer, General Contractor, or Subcontractors
The parties responsible for developing or constructing the building may face claims if their work caused the defect and the legal requirements for recovery are met.
A roofing subcontractor’s installation, for example, may need to be evaluated separately from the general contractor’s coordination of the roof and exterior wall assemblies.
Purchasing an existing building does not automatically eliminate potential construction claims. It also does not guarantee that every contract or warranty right transfers to you. Ownership history, assignments, warranty language, and the type of claim matter.
Architects, Engineers, and Other Design Professionals
A design professional may bear responsibility when a design deficiency or failure to meet an applicable professional standard caused damage.
Determining whether a problem originated in the plans, field installation, or later alterations often requires a qualified expert’s investigation. The location where damage appears may not identify the party that caused it.
Does Buying a Commercial Property “As Is” Prevent a Claim?
An “as is” clause can significantly affect your rights, but it does not automatically defeat every claim involving concealment or misrepresentation.
California courts have recognized that accepting a property’s observable condition is different from waiving claims involving concealed defects or misleading statements. The language and circumstances of the transaction remain important.
Commercial purchase agreements may also include releases, limits on representations, inspection requirements, and provisions addressing reliance on the seller’s statements. Each provision deserves careful review.
Do not assume that “as is” means you have no options. Likewise, do not assume that every undisclosed problem creates a valid claim.
What If the Building Passed a Pre-Purchase Inspection?
A completed inspection does not establish that the building was free of hidden construction defects. Some problems are concealed inside walls, beneath roofing materials, or below a concrete slab.
California distinguishes between:
- Latent defects: Deficiencies not apparent through reasonable inspection.
- Patent defects: Deficiencies apparent through reasonable inspection.
An inspection report is still important evidence. It may document conditions before closing, identify areas excluded from the inspection, or reveal warning signs that required additional investigation.
Whether an inspector bears responsibility requires a separate review of the inspection agreement, scope of work, applicable duties, and what reasonably should have been identified.
How Long Do You Have to Bring a Commercial Construction Defect Claim in California?
There is no single deadline that applies to every commercial construction defect claim. Your purchase date does not generally restart the original construction deadlines.
California Code of Civil Procedure section 337.15 generally establishes a 10-year outer limit after substantial completion for specified latent construction defect claims against covered construction participants. Shorter claim-specific deadlines can expire earlier, and statutory exceptions may apply.
Section 337.1 generally establishes a four-year outer limit after substantial completion for specified patent-defect claims, subject to its provisions and exceptions.
Consider a building substantially completed eight years before you purchased it. Discovering a hidden defect shortly after closing does not generally give you a new 10-year period to pursue the original construction participants.
Seller-related claims, contract claims, and claims involving later improvements may require different deadline analyses. Repair discussions alone should not be treated as protection against an approaching deadline.

Does California’s SB 800 Right to Repair Act Apply to Commercial Buildings?
SB 800 generally does not govern purely commercial construction. Civil Code section 896 describes its application to original residential construction intended to be sold as individual dwelling units. Commercial owners should not assume that residential construction standards or claim procedures apply to an office building, warehouse, or retail center.
Mixed-use properties require closer analysis because the residential and commercial components may raise different legal issues.
What Should You Do After Discovering a Defect?
Address immediate hazards, document the condition, preserve records, and obtain qualified advice promptly.
- Protect occupants and limit further damage. Arrange necessary emergency measures when a condition threatens safety or allows damage to continue.
- Photograph the problem. Record affected areas, dates, weather conditions, and recurring symptoms.
- Gather transaction documents. Preserve the purchase agreement, disclosures, inspection reports, seller communications, and warranty documents.
- Collect the building’s history. Locate plans, permits, maintenance logs, repair invoices, and tenant complaints.
- Obtain a qualified investigation. Ask an appropriate expert to evaluate the cause and extent of the problem.
- Coordinate evidence preservation before major repairs. When feasible, document conditions before they are covered or removed. Do not delay necessary emergency work.
- Have deadlines and notice requirements reviewed. An attorney can assess potential claims and any applicable contractual procedures.
A patch may stop today’s leak without correcting the underlying defect. Understanding the cause helps you make better repair decisions and identify potentially responsible parties.

Frequently Asked Questions About Commercial Property Construction Defects
Can I sue the seller for construction defects discovered after closing?
Possibly. A claim may exist if the seller made actionable misrepresentations, concealed information they were required to disclose, or breached the purchase agreement. Discovering damage after closing does not automatically prove seller liability.
Can I pursue the original builder if I bought the property from someone else?
Potentially. A later purchaser may have available claims, but the answer depends on the legal basis, building history, damage, contract rights, and deadlines. Buying the property does not restart the construction clock.
Who pays for repairs while responsibility is being investigated?
You may need to arrange and initially pay for urgent repairs to protect occupants and limit damage. Whether those expenses can be recovered from another party depends on liability, supporting evidence, and available remedies.
Does an “as is” purchase mean I accepted hidden construction defects?
It can affect the risks you accepted, but it does not automatically bar every concealment or misrepresentation claim. The complete purchase agreement and surrounding facts must be reviewed.
Should I wait for the seller or contractor to attempt repairs before contacting an attorney?
If significant damage or a potential deadline is involved, seek advice promptly. A repair promise or ongoing negotiation should not be assumed to extend your time to bring a claim.
