A property certification, occupancy process, dye test or unresolved permit can affect a closing. The checklist depends on the exact municipality and legal use of the home.

You can prepare a house beautifully, price it correctly, accept a strong offer, and still run into a closing delay because of a municipal requirement nobody discussed at the beginning.
That is especially possible around Pittsburgh. Allegheny County is made up of 130 municipalities, and the rules can change when you cross a borough line. One community may require an occupancy inspection when ownership changes. Another may require a sewer dye test. Inside the City of Pittsburgh, the process is different again.
This is not a reason to panic or order every inspection you can find. It is a reason to identify the property’s municipality early and build the correct requirements into the selling timeline.
The short answer
A Pittsburgh-area sale can be delayed by four broad categories of local requirements:
- Property or zoning certification
- Occupancy permits or municipal inspections
- Sewer dye testing or related compliance letters
- Open permits, code violations, municipal claims, or tax certifications
They are not interchangeable. A home inspection performed for a buyer is not the same thing as a municipal inspection. A dye test does not certify the entire condition of the house. A property certification does not guarantee that every improvement was properly permitted.
The correct checklist depends on the exact address, its legal use, and the municipality handling it.
City of Pittsburgh versus a surrounding municipality
This is where many owners understandably get confused.
The City of Pittsburgh states that it does not require a Certificate of Occupancy simply to buy or sell a property. The City also notes that this does not mean the property complies with every zoning and building rule. A buyer may need an occupancy permit if the present use is different from the use shown on the current certificate. Older single-family homes may not have a Certificate of Occupancy on file because previous regulations did not require one. City of Pittsburgh: Online Occupancy Search
For a City closing, however, a property certification is required. That document reports the zoning classification and legality of use, whether an occupancy permit is on file, local historic status, and active code violations or unsafe conditions. The current application fee listed by the City is $100. City of Pittsburgh: Property Certification
Move outside the City, and a different local process may apply.
For example, Mt. Lebanon requires point-of-sale dye-test paperwork. Its official instructions say evidence of compliance and the $50 fee must be submitted at least 10 business days before closing. If interim compliance is needed because of weather or a failed test, the request must be submitted at least 14 business days before closing. Mt. Lebanon also says violations, open permits, and dye-testing requirements must be resolved before certain municipal and tax letters are released. Mt. Lebanon: Dye Testing
Plum Borough takes another approach. Its published guidance says a residential occupancy permit is required when the occupancy of a residence changes, while its community-development page describes the requirement as applying when ownership or residents change, subject to its timing rule.

The takeaway is simple: “Pittsburgh” is not one transfer process.
What actually causes the delay?
1. Waiting until the closing date is already close
Municipal review takes time. Weekends, holidays, missing signatures, unavailable inspectors, and required reinspections can turn a small issue into a scheduling problem. Mt. Lebanon’s 10-business-day submission window is a good example of why this work cannot always wait until the final week.
2. The property’s legal use does not match its current use
This often matters with older homes that have been divided into units, converted back to a single-family home, or used differently over time. A listing may call a property a duplex, but the municipal record may show one dwelling unit—or the reverse.
That does not automatically mean the property cannot be sold. It does mean the discrepancy should be understood before marketing promises are made and before a buyer’s lender or appraiser discovers it.
3. A dye test reveals an improper stormwater connection
A dye test is intended to show where water is flowing. Downspouts, driveway drains, sump pumps, and other drains may be tested. If stormwater is improperly connected to a sanitary sewer, corrective work or an approved interim process may be needed.
The cost is not always the test itself. The larger question is what must be repaired, who will complete it, whether the municipality permits an escrow arrangement, and whether the work can be finished before settlement.
4. Old permits or violations are still open
A project may look finished while the paperwork remains incomplete. A prior owner may have started work under a permit but never obtained a final approval. An active code violation may also appear during certification or title work.
The earlier these records are reviewed, the more options a seller usually has.
5. The contract is vague about responsibility
“As-is” does not necessarily erase a municipal obligation. A buyer may agree not to request ordinary repairs and still expect the seller to deliver documents required for closing. Local rules may also control whether a responsibility can be transferred or escrowed.
The agreement should clearly address who orders required inspections, who pays the fees, who handles repairs, and what happens if compliance is not available by the scheduled closing.
A practical timeline for Pittsburgh-area sellers
Before the house is listed
Confirm the exact municipality—not only the mailing address or school district. Then ask for the current point-of-sale, occupancy, dye-test, tax, and municipal-claim requirements. If the property has multiple units or a nonstandard use, verify the legal use and available occupancy record.
During listing preparation
Order any items with long lead times. Gather records for additions, finished basements, decks, electrical work, sewer repairs, and prior occupancy approvals. You do not need a perfect archive, but the documents you already have can help resolve questions quickly.
When reviewing an offer
Compare more than price. Look at the closing timeline, inspection terms, financing, appraisal risk, municipal-repair language, and the buyer’s flexibility if additional review is needed. A clean plan can be more valuable than a rushed closing date that the local process cannot support.
Before closing
Confirm that the title company, municipality, buyer, and seller have the required approvals and receipts. If a repair, reinspection, or escrow arrangement is involved, make sure the written terms are understood before everyone arrives at the closing table.
Four common myths
“The buyer’s home inspector passed the house, so municipal compliance is handled.” A buyer’s inspection and a municipal requirement serve different purposes.
“There is no Certificate of Occupancy, so the City house is illegal.” Not necessarily. Pittsburgh says some older single-family homes may have no certificate because earlier rules did not require one.
“The county assessment tells us what the house is worth.” Allegheny County expressly says assessed values are not current market values and explains that it uses a 2012 base-year methodology. Assessment data is useful, but it is not a substitute for current comparable sales, property condition, and market response. Allegheny County Real Estate Portal disclaimer
“Selling as-is means the seller has no paperwork or compliance responsibilities.” As-is usually speaks to repair negotiations; it does not automatically override municipal rules or the written sales agreement.
The no-pressure bottom line
Most municipal issues are manageable when they are found early. The problem is rarely that a form exists. The problem is discovering the form, failed test, legal-use question, or open permit after the moving truck and closing date are already scheduled.
If you are thinking about selling, start with the address. I can help identify the local process, explain how it may affect timing and selling options, and connect you with the appropriate municipal office, title professional, plumber, contractor, or other specialist when needed. You can get the facts first and decide what makes sense from there—without pressure to list.
