Oshawa Building Permit & Structural Engineering FAQs
How do I know if a wall is load-bearing in my Oshawa home?
It’s not always obvious. Some walls are just room dividers, but others are carrying floor or roof loads. The quickest way to confirm is to look at joist direction, what’s supported below (basement/crawlspace), and whether there are posts or beams lined up underneath.
- On-site review of framing & supports
- Clear answer + next steps if it’s structural
Do I need a permit to remove a load-bearing wall in Oshawa?
Most of the time, yes. If you’re changing structural framing, the City typically expects a building permit and engineered drawings. It also helps protect you later with insurance and when you sell.
- Beam sizing (LVL or steel) + post layout
- Temporary shoring plan for safe construction
I’m planning a legal basement apartment in Oshawa — what gets reviewed?
Most second-unit reviews come down to life-safety: safe exits, fire separation, and layouts that meet code. If you’re cutting new openings, moving beams, or changing framing, structural details are reviewed too.
- Egress + exit/window requirements
- Fire separation details
For a home addition in Oshawa, what do you actually design?
We design what keeps the addition standing and tied into your existing home: foundations/footings, floor framing, roof framing, and the connection details so it performs well long-term.
- Foundations + structural framing
- Tie-ins to the existing structure
Do decks, porches, or patio covers need permits in Oshawa?
Often, yes — especially if it’s elevated, attached to the house, multi-level, or has a roof. Permits usually focus on footing depth, spans, connections, and guardrail safety.
- Footing depth + framing spans
- Guardrails + strong connections
Can you help if the City of Oshawa asks for revisions?
Yes. If the reviewer asks for clarifications, we update the drawings and respond with clear notes so your permit application can keep moving without unnecessary delays.
- Municipal comment support
- Fast revisions when needed
