Structural Engineering · Hamilton
Structural engineering for Hamilton’s older single-detached houses and its commercial units: beams and posts where a bearing wall is removed, underpinning for a lowered basement, footings for additions and converted rear garages, steel and OWSJ framing, and engineer’s letters, all stamped by our own P.Eng and filed through the Customer Portal.
What’s included
Structure is the sheet the permit examiner reads most carefully. Ours is designed by the engineer who visited the site, drawn so a framer or a fabricator can build from it, and stamped in-house. In Hamilton the package goes to the City of Hamilton Building Division, and it is drawn to that department’s checklist.
Custom homes & additions
Beams, joists, posts and roof framing sized for the spans and loads of the building, balancing strength, efficiency and the architecture.
Foundations & slabs
Footings, foundation walls, underpinning and slabs designed for the soil and the loads above, for long-term performance.
Commercial & industrial
Steel framing for commercial units and industrial buildings, with the beams, columns, joists and connections detailed for fabrication.
Inspections & letters
Evaluation of what is already built: structural inspections, responses to city letters, code compliance reviews and special solutions for hard sites.

How it runs
Four steps from a site visit to a stamped set. The engineer who sees the framing is the one who signs the drawings.
We look at what carries what: framing direction, bearing walls, foundation condition and anything the last renovation hid. Photos and measurements go into the file.
Dead, live, snow and wind loads are worked out for the building and the site, and the load path is traced from the roof to the footings.
Members and connections are sized, detailed and drawn so a framer or a steel fabricator can build from them without guessing, then stamped by our P.Eng.
We answer the examiner’s structural comments at no extra charge and, where the permit requires general review, inspect at the stages the city sets and issue the field reports.

Anything we haven’t answered here, we’ll answer on a call. The first consultation is free.
(416) 990-9179A building permit from the City of Hamilton Building Division, because both alter or extend the structure of the house. Hamilton’s Site Alteration By-law 19-286 applies to all land in the city, including residential lots, with written exemptions for minor landscaping and for work under an issued building permit. Underpinning done under its building permit is the kind of work that exemption describes, but a free-standing retaining wall or a regraded yard may need an application of its own. Where the design has to be engineered, our P.Eng stamps it and signs the Commitment to General Reviews the permit calls for.
If the lot is inside the Hamilton Conservation Authority (HCA) regulated area, yes. Ontario’s Conservation Authorities Act prohibits development in hazardous lands, wetlands, river or stream valleys and shorelines at risk of flooding or erosion unless the authority issues a permit. We design the footings to its conditions and settle that permit with the HCA, then apply to Hamilton for the building permit.
Yes. We take on structural engineering across Hamilton, including Ancaster and Dundas, within an hour of our Richmond Hill office. The first consultation is free, by phone or on site.
Three things to start: property address and what you plan to change; existing drawings or previous permits, if any; and photos of the framing, the foundation or the problem area. Send those and we tell you what the City of Hamilton Building Division will ask for before we quote.
Yes. Removing a wall that carries load alters the structure, so it needs a permit from the City of Hamilton Building Division before any demolition starts, while our P.Eng designs and stamps the beam and posts that take over its load. In an older single-detached house the new posts usually need footings of their own, since a basement slab is not designed to carry a point load, and those footings go on the same sheets in the Customer Portal upload.
It can. Private trees are protected under the by-law of the former municipality the lot is in, for example 4401-96 in Stoney Creek, and many front lawn trees are City trees under By-law 15-125. Digging for a pier, a strip footing or underpinning close to one can damage its roots, so our P.Eng lays the footings out around the trees shown on the survey and warns you early if a tree permit looks likely.
Indirectly, through the form the district accepts. In Cross-Melville, Melville-Park West, St. Clair Boulevard and the City’s five other Part V districts, the height, roofline and placement of an addition are settled against the district first. Our P.Eng then sizes the beams, joists and footings for that shape, and the structural sheets are filed with the architecture in one application to the City of Hamilton Building Division.
Yes. A City of Hamilton Building Division inspector asks for one when what is on site differs from the approved sheets, such as a beam of another size, or a joist notched during an earlier renovation of an aging Hamilton house. Our P.Eng visits, checks the member against its loads, and either confirms it in a stamped letter or designs the fix.
Only a site check can say. Our P.Eng opens up the framing and checks the walls and footings against the added loads, since the original drawings for an older single-detached house are seldom on hand. The zoning comes first, though: most lots take their height and setback rules from By-law 05-200, and some still from a former community by-law such as 6593 in the former City of Hamilton or 3581-86 in Dundas.
Yes. For a Hamilton commercial unit our P.Eng designs and stamps the steel: beams and columns to open up a floor, OWSJ framing for a roof or a mezzanine, and the connections that tie them together. When the work comes with a new use, we first confirm that By-law 05-200, or the former community by-law where one still applies, allows that use at the address. The stamped sheets are filed in the same Customer Portal application as the fit-out, and the examiner reads them alongside the floor plan.
Yes. Cutting a door into the foundation wall needs a lintel over the opening and retaining walls along the new stairwell, and our engineer sizes both for the permit set. Hamilton allows an Additional Dwelling Unit inside the main house, and some zones allow up to four units on the property, so we check how many units the lot already has before the opening is drawn for the City of Hamilton Building Division.
Searched & answered
Short answers to the structural engineering questions people search most, and the broader topics they lead to.
Not covered here? Book a free consultationUnderpinning deepens an existing foundation by building new footings beneath the old ones, one short section at a time, so the house stays supported throughout. It is the usual way to lower a basement for more headroom, and it is also used to repair a foundation that has settled. Fine Engineering designs the sequence and the new footings, then reviews the stages the permit calls for on site.
A structural engineer works out how a building carries its loads from the roof down to the footings, then sizes the beams, columns, joists and foundations to carry them safely. On a house that usually means wall removals, additions, underpinning, or a look at cracks and sagging floors. At Fine Engineering the P.Eng who designs the structure also stamps the drawings.
Once a complete application is in, Ontario’s Building Code gives the municipality 10 business days to issue a house permit or refuse it with reasons. Larger and more complex buildings get a longer period. The count only starts when nothing is missing, so an absent sheet or an unresolved zoning issue holds it back. Fine Engineering checks zoning and code before anything is submitted.
The application form, the drawings the Building Code calls for, and every other approval the project depends on. Zoning counts as applicable law, so a needed minor variance has to be granted before the permit can be issued, and a lot in a conservation authority’s regulated area may need that authority’s permit first. Fine Engineering assembles the whole package, with the designer’s registration details on the drawings.
Most often because the plans do not show that the work meets the Building Code or applicable law, such as the zoning by-law. A permit is also withheld when the law requires an engineer’s or architect’s design and the drawings lack one, or when the builder of a new home is unlicensed. The refusal must state its reasons, and Fine Engineering revises the set to answer each one.
Stop work and start on the drawings. A stop-work order usually means construction began without a permit or departed from the approved plans. Getting out of it takes a permit application that shows what was built and what is proposed, then whatever inspections the city asks for. Fine Engineering prepares those drawings and replies to the city’s letters.
Good to know
In Hamilton the reviewer is the City of Hamilton Building Division. Every Hamilton lot sets its own terms: the age of the framing, what the last renovation hid and how the load reaches the foundation all shape the design.
We walk the site with the survey on a scheduled visit before anything is drawn, then file the structural engineering package to the City of Hamilton Building Division’s own checklist.
Hamilton has an aging stock led by single-detached houses, with the age of housing varying widely from ward to ward. Older houses rarely come with drawings and have often been renovated already, so we open the framing and confirm what the last change did to the load path.
When a Hamilton basement is lowered, the underpinning drawings number the dig sequence, and the depth, the soil and the neighbouring footings decide whether that design has to be engineered. For an aging stock led by single-detached houses, we open a test pit at the existing footing to measure its depth and condition.
The HCA is not the only conservation authority in Hamilton. East Stoney Creek and Glanbrook are under the Niagara Peninsula Conservation Authority, and parts of Flamborough under the Grand River Conservation Authority. Which one reviews a footing depends on where the lot sits, so we check the lot against each authority’s mapping.
The HCA, the GRCA and the NPCA all work under Ontario Regulation 41/24, which regulates a valley with stable slopes to the stable top of the bank plus 15 metres and extends the prohibition on development to 30 metres from a wetland.
Hamilton’s Additional Dwelling Unit rules let an existing accessory building, such as a garage at the back of the yard, become a detached unit, and from then on it is designed as a dwelling. A garage slab may not have footings below frost depth, and its walls and roof were framed for storage rather than for insulation and interior finishes. Our P.Eng checks the slab edge and the framing before the conversion is designed.
Once a structural permit is issued, the inspections the City of Hamilton Building Division carries out at each stage are requested through the Customer Portal, under Permitting and Inspections. Where our P.Eng has committed to general reviews, we arrange the engineer’s site visits with those stages in mind, so the designer has seen the footing or the new beam by the time the City’s inspector arrives.
