What Real Estate Lawyers Actually Check About Permits When You Sell

Real estate lawyers performing standard due diligence on a home sale check title for registered encumbrances and request municipal work order searches that reveal active violations, outstanding property standards orders, and unpaid charges. What they do not routinely check is building permit history. That requires a separate search most buyers never order. This means a finished basement, converted garage, or second-floor addition can close without anyone confirming whether permits were pulled, inspections passed, or the work was ever legally completed. The gap between what lawyers check and what actually exists on the property is where permit problems hide until they become your problem.

The Standard Title Search and What It Actually Reveals

Every real estate transaction in Ontario involves a title search through the Land Registry Office. Your lawyer examines the parcel register to confirm ownership, identify registered mortgages, and flag any encumbrances that affect the property. This search catches liens registered against title, easements, rights of way, and restrictive covenants. If the city has registered a lien for unpaid property taxes or a demolition order, it shows up here.

What the title search does not reveal is whether the physical structure matches what was legally permitted. A homeowner could have added a second storey, converted their garage to living space, and installed a basement apartment without pulling a single permit. None of that appears on title. The parcel register describes the legal lot and registered interests, not the building envelope or interior configuration. Lawyers checking title are confirming you can legally transfer ownership, not that the building complies with the Ontario Building Code.

Municipal Liens That Do Appear

When municipalities escalate enforcement to the point of registering charges against title, those do show up. This happens with unpaid property standards fines, emergency repairs the city performed and billed to the owner, or demolition liens for unsafe structures. But registration is the final step in a long enforcement process. Most permit violations never reach this stage. A property can have multiple outstanding building code violations that remain unregistered because the city is still in the notice and order phase.

Municipal Work Order Searches: What They Catch and Miss

Beyond the title search, lawyers typically order a municipal work order search, sometimes called a compliance letter or status certificate request for freehold properties. This search asks the city whether there are any outstanding work orders, property standards orders, or compliance issues registered against the property. In Toronto, this goes through the Municipal Licensing and Standards division. Other GTA municipalities have similar processes through their building or bylaw departments.

The work order search catches active enforcement. If a bylaw officer issued a property standards order for an unsafe deck, it appears here. If the fire department flagged an illegal rooming house, that shows up. Outstanding zoning violation notices, orders to comply, and active court proceedings related to the property all get captured. This gives buyers visibility into problems the city has already identified and is actively pursuing.

The work order search tells you what the city is currently upset about. It tells you nothing about what the city doesn't know yet.

Here is the critical gap: work order searches only reveal violations the city has discovered and documented. If a homeowner finished their basement without permits and no inspector ever visited, no complaint was ever filed, and no fire or flood ever triggered municipal attention, that unpermitted basement does not appear on any work order search. The city has no record of the violation because they have no record of the work. From the municipality's perspective, the basement is still unfinished.

The Timing Problem

Work order searches reflect a snapshot in time. If a neighbor files a complaint about your illegal second unit the week after the search was completed, that violation will not appear in the results the buyer's lawyer received. Municipalities do not proactively update lawyers about new orders. The search reflects conditions as of the date it was run, and closings often happen weeks or months later.

Building Permit History Searches: The Search Most Buyers Skip

The only way to confirm whether renovations were permitted is to request a building permit history search directly from the municipal building department. This is a separate search from title and work order inquiries. It requires a specific request, often involves a fee, and typically takes longer to process. Most importantly, it is optional. Neither buyers nor their lawyers are required to order it, and in standard transactions, they often do not.

A building permit history search returns a list of permits issued for the property, their scope, and their status. You learn whether a permit was applied for, whether it was issued, and critically, whether it was closed out with final inspection approval. An open permit from fifteen years ago for a basement renovation tells you the work was started but never signed off. A missing permit for work that clearly exists tells you it was never permitted at all.

Why Lawyers Do Not Automatically Order This

Real estate lawyers are not building inspectors. Their role is to facilitate the legal transfer of property and protect their client from title defects. Building permit compliance falls into a gray area. Most lawyers will advise buyers that they can order a permit history search if they have concerns, but they do not include it as standard practice. The search adds time, costs money, and in many transactions, the buyer is not particularly worried about permit history.

This creates an information asymmetry that benefits sellers with unpermitted work. Unless something triggers the buyer to dig deeper, the permit gaps remain invisible through closing. The new owner inherits whatever compliance issues exist, often without knowing they exist until they try to sell, refinance, or renovate years later.

What Actually Triggers Deeper Investigation

Certain red flags prompt buyers or their lawyers to order enhanced due diligence including building permit history searches. Understanding these triggers helps sellers anticipate where their transaction might hit friction.

• Visible additions or structural changes that do not match property records or listing history
• Basement apartments, secondary suites, or rental units that raise questions about legal status
• Recent major renovations disclosed by the seller without corresponding permit documentation
• Home inspection findings that suggest work was done without proper permits or inspections
• Discrepancies between the listing square footage and municipal assessment records
• Insurance requirements for rental properties that demand proof of legal compliance
• Mortgage lender concerns about property condition or legal use

In hot markets where buyers compete for properties, enhanced due diligence often gets skipped in favor of speed. In slower markets where buyers have leverage, permit history searches become more common. Savvy buyers purchasing income properties almost always investigate permit status because their rental income depends on the units being legal.

The Home Inspection Connection

Home inspectors are not permit specialists, but experienced inspectors notice signs of unpermitted work. Electrical panels with amateur wiring, plumbing runs that do not meet code, structural modifications without proper engineering, and basement bedrooms without egress windows all raise questions. When an inspector flags these issues, buyers often follow up with permit history searches. At PermitsHub, we regularly help homeowners who discover permit problems this way, often weeks before their planned closing date.

Municipality-Specific Search Processes Across the GTA

Each GTA municipality handles permit history searches differently. Toronto maintains records through its Building Division and offers online access to some permit information through the Application Information Centre, though complete historical records often require formal requests. Mississauga, Vaughan, Markham, and other municipalities have their own processes, response times, and fee structures.

Older properties present particular challenges. Records from before digital systems were implemented may be incomplete, missing, or difficult to locate. A house built in the 1950s with renovations done in the 1980s may have permit records that exist only in paper archives, if they exist at all. Some municipalities cannot confirm permit status for work done before certain dates. This does not mean the work was unpermitted, but it does mean proving compliance becomes difficult.

What Sellers Should Know About Records

If you have documentation from your own renovations, including permits, inspection records, and contractor invoices, organize these before listing. Proactive disclosure of permitted work reassures buyers and reduces the chance they will order their own investigation. If you know certain work was done without permits by previous owners, consider whether addressing it before sale makes sense. At PermitsHub, we help sellers evaluate their options, whether that means retroactive permitting, disclosure strategies, or pricing adjustments that account for compliance risk.

The Seller's Disclosure Obligation

Ontario's standard Agreement of Purchase and Sale includes seller representations about the property. While sellers are not required to warrant that all work was permitted, they are required to disclose known material defects. Whether unpermitted renovations constitute a material defect that must be disclosed is a legal question that depends on circumstances. Sellers who actively conceal permit problems face greater liability than those who simply did not know.

The practical reality is that most sellers know whether they pulled permits for their own renovations. What they often do not know is whether previous owners did. If you bought a house with a finished basement and assumed it was permitted because it looked professional, you may genuinely not know its permit status. This is different from finishing your own basement without permits and hoping nobody asks.

The seller who says nothing about permits is in a very different position than the seller who says the basement was permitted when they know it was not.

What Happens When Problems Surface Before Closing

When permit issues emerge during due diligence, transactions can proceed in several directions. Buyers may request a price reduction to account for the cost and risk of addressing compliance issues. They may require the seller to obtain retroactive permits or complete required work before closing. In some cases, buyers walk away entirely, particularly if the issues affect their intended use of the property or their ability to insure it.

Sellers facing these situations need to respond quickly. Retroactive permitting takes time, and closing dates do not always accommodate the municipal process. Understanding what can realistically be resolved before closing versus what requires renegotiation is critical. Some issues, like open permits that just need final inspection, can be resolved in days. Others, like unpermitted structural work that requires engineering review, may take months.

Holdbacks and Escrow Arrangements

When permit issues cannot be fully resolved before closing but both parties want the transaction to proceed, lawyers sometimes arrange holdbacks. A portion of the purchase price is held in escrow until the seller completes specific remediation or obtains required permits. This protects the buyer while allowing the sale to close. The terms of holdback arrangements vary widely depending on the nature and severity of the permit issues.

Protecting Yourself as a Seller

The best protection against permit problems derailing your sale is addressing them before listing. Order your own permit history search to understand what records exist. Review your files for permits and inspection documentation from your renovations. Identify any work you know was done without permits and evaluate your options.

For work that was never permitted, you have choices. Retroactive permitting is possible in many cases, though it requires drawings, inspections, and sometimes opening up finished work to verify compliance. Disclosure without remediation is another path, pricing the property to reflect the compliance risk. Doing nothing and hoping it does not come up is technically an option, but it carries meaningful legal and financial risk if issues surface later.

PermitsHub works with sellers across the GTA who need to resolve permit issues before closing. Whether that means preparing drawings for retroactive permits, coordinating expedited inspections, or simply helping you understand what your permit history actually shows, getting ahead of these issues protects your sale.
