Townhouses in Ajax, Pickering and Clarington look simple from the street, but buyers miss the same seven things over and over: shared roofs and walls, freehold vs condo ownership, grading between units, and follow-up before the condition date. A townhouse inspection is not a scaled-down detached-house inspection. Your inspector is Yama Nehan, a Certified and Registered Home Inspector with 15 years of home inspection experience. To book, call 647-704-7100 or book an inspection online.
Key takeaways
- Know whether the townhouse is freehold or condo/stacked before you book. What gets inspected, and who maintains the roof, changes completely.
- Shared walls, attic separations and drainage between units matter as much as the kitchen and furnace.
- End units and rear-walkout units have their own weak spots: extra exterior wall, taller foundations and finished-basement add-ons.
- Plan specialist follow-ups (sewer scope, roofer, electrician) before your condition date, not after you go firm.
- Home inspections start from $499 and condo inspections from $399. The final price depends on the property.
East Durham has plenty of townhouse stock: freehold rows in south Ajax and Pickering, newer freehold and condo townhomes in north Ajax and Courtice, and stacked units in Clarington.

7 townhouse inspection mistakes buyers make
1. Treating every townhouse like a detached house
A detached house stands alone. A townhouse shares walls, often a continuous roof, and a tight strip of yard with the units beside it. Buyers who only ask about the kitchen, furnace and basement finishes miss the surprises: water along a shared roof valley, a gap in the attic fire separation, or downspouts dumping between units. A full home inspection still covers structure, roof, exterior, electrical, plumbing, heating, insulation and interior — on a townhouse, extra time goes where the units join.
2. Skipping the freehold vs condo (or stacked) distinction
This is the biggest booking mistake. In Ajax, Pickering and Clarington you will see:
- Freehold townhouses — you own the building and the land. You are responsible for the roof, exterior, foundation and yard.
- Condo townhouses and stacked townhomes — the corporation usually maintains the roof, exterior and foundations. The inspection focuses on the unit and exclusive-use areas.
Book the wrong type and you waste time on a common roof the board looks after, or skip the costliest systems on a freehold row. Confirm ownership with your agent before you book. See our condo inspection page and condo inspection in Pickering, Ajax, Whitby and Oshawa.
3. Not checking roof access — and who maintains the roof
On a freehold townhouse, the roof is yours. I check shingles, flashing at walls and valleys, vents and eavestroughs where it is safe. Shared valleys are common leak points; a top-floor stain may start on the neighbour’s side of the ridge. On a condo or stacked townhouse, the corporation usually maintains the roof — I note ground-level issues that affect your unit, but I do not walk a common roof. Ask who pays when the roof fails; that changes what needs attention before your condition date.
4. Ignoring grading, rear walkouts and shared drainage
Townhouse lots here are narrow. Water has nowhere to go except between units or toward a rear walkout. A situation we often see: downspouts from two units empty into the same side path, grading is flat, and the end-unit basement shows damp patches on the shared wall. On rear-walkout units (common toward Lake Ontario and in parts of Courtice and Bowmanville), I also check the taller foundation, walkout door, deck framing and lower-level drainage.
5. Missing party walls, firewalls and attic separations
The wall between two townhouses is meant to slow fire and sound. In the attic, that separation should run continuously to the underside of the roof. Gaps, holes cut for wiring or fans, and missing drywall are findings I photograph. I also check the party wall in the basement for cracks and dampness. End units have one party wall instead of two, but more exterior wall and weather exposure — a different trade-off, not an easier one.
6. Skipping the electrical panel and finished-basement add-ons
End units and larger freehold townhouses in north Ajax, Pickering and Clarington often have finished basements or DIY electrical from a past renovation. I check the panel, visible wiring, grounding and GFCI near water. Amateur basement circuits and double-tapped breakers show up regularly. If the basement was finished later, ask the seller for permits. The inspection is visual and non-invasive, so paperwork plus what we see at the panel tells you whether an electrician should follow up before you go firm.
7. Not planning follow-up before the condition date
Most GTA conditional offers give you only a few business days. Buyers who open the report the night before leave no time for a sewer camera scope, a roofer’s quote or an electrician. On townhouses I often recommend a sewer scope when the home is older, drains are slow, or shared grading raises questions — book it while the condition is still open. Attend if you can. You get a written report with photos within 24 hours; block time the same day to read it with your agent.
Freehold townhouse vs condo / stacked townhouse: what gets checked
| Area | Freehold townhouse | Condo / stacked townhouse |
|---|---|---|
| Roof and exterior | Fully inspected where safely accessible | Usually corporation responsibility; we note issues that affect your unit |
| Foundation and grading | Full perimeter, downspouts, rear walkouts, shared side paths | Unit-level moisture signs; common exterior usually not our scope |
| Party wall / attic separation | Checked in attic and basement where accessible | Checked where accessible inside the unit |
| Electrical and plumbing | Panel, visible wiring, fixtures, water heater, drains | Same inside the unit; shared building systems are corporation scope |
| Heating and cooling | Furnace/boiler, A/C, venting for the dwelling | Equipment that serves only your unit |
| Interior and basement | Full interior, finished basement, water and movement signs | Full unit interior; exclusive patios as access allows |
| Who pays for big repairs | You (roof, exterior, foundation) | Usually the corporation (confirm in the status certificate) |
Townhouse inspection checklist for Ajax, Pickering and Clarington buyers
- Confirm freehold vs condo/stacked with your agent before booking
- Condition date noted, with time reserved to read the report the day it arrives
- Roof: who maintains it, age if known, valleys and flashing at shared walls
- Attic: continuous fire separation, insulation, stains, fans venting outdoors
- Party wall in basement: cracks, dampness, unfinished gaps
- Grading and downspouts between units; rear walkout drainage if applicable
- Electrical panel, GFCI near water, any basement add-on wiring
- Furnace and water heater age and venting
- Windows, sliding doors and exclusive-use decks or patios
- Plan for sewer scope or specialist quotes if recommended
- Status certificate ready if it is a condo townhouse
In older townhomes, vermiculite-like attic insulation or other suspect materials can come up. If you want those checked, we can arrange home hazard testing alongside the inspection.
Townhouse inspection FAQ
Do I need a different inspection for a condo townhouse than a freehold townhouse?
Yes. Freehold townhouses are inspected like a house you fully own. Condo and stacked townhouses focus on the unit and exclusive-use areas. Tell us which type you are buying when you book.
Should I attend the townhouse inspection?
Yes, if you can. Shared walls, valleys and grading are easier to understand in person. If you cannot stay for the whole visit, come for the final walkthrough.
What does a townhouse inspection cost?
Home inspections start from $499 and condo inspections from $399. The final price depends on the property — mainly size, age, type and any added services such as hazard testing.
