Permits in Hamilton
A City of Hamilton building permit is not required for landscaping such as a paver patio. A Site Alteration Permit is required where the work alters the grade of land, and the landscaping exemption only holds where fill is 15 cm or less at any point, drainage to neighbouring properties is unchanged, and no swale is blocked. Where a permit is needed the residential (minor) fee is $1,155.

Moderate confidence. Based on published Ontario and GTA cost ranges, adjusted for local labour.
What an interlocking patio costs in Hamilton comes down to what happens below grade before a single paver is placed, not the paver itself. A base built to withstand seasonal freeze-thaw cycling needs to be excavated and compacted well beyond what a walkway or a warmer climate would need, and skipping that depth is the most common reason a patio heaves or settles unevenly within a few winters. Ask a contractor how they're building the base before you compare their per-square-foot number to anyone else's.
What drives your price
Base excavation and compaction
Digging out and compacting a frost-resistant granular base is the most labour-intensive part of the job and the step most likely to be shortcut by a low bid, since it's invisible once the pavers are down.
Paver material and pattern
Concrete pavers, natural stone-look product, and the premium lines Hamilton-area dealers carry vary widely in unit price, and a herringbone or running-bond pattern with cut borders takes longer to lay than a simple grid.
Excavation spoil and site access
Removing and hauling away the soil displaced by a deep base adds cost that scales with patio size, and a backyard reachable only through a narrow side gate or over an existing deck adds hand-carrying time that a skid-steer could otherwise do.
Edge restraint and drainage detailing
Proper edge restraints keep the pattern from spreading over time, and grading the patio surface to shed water away from the foundation instead of toward it is a detail that separates a patio that lasts from one that doesn't.
What this means in Hamilton
Frost-depth base preparation
Hamilton's winters put the ground through repeated freeze-thaw cycles, and a base that isn't excavated and compacted to a locally appropriate depth will heave unevenly as frost moves through it, typically showing up as lippage or gaps within the first couple of winters rather than right away. This is a climate and soil condition rather than a single fixed rule, so ask any contractor quoting the job how deep they're excavating and what base material they're using before comparing prices.
Site Alteration By-law 19-286 and grading
A City of Hamilton building permit is not required for a paver patio, but Site Alteration By-law 19-286 requires a separate Site Alteration Permit where the work changes the grade of the land, and the landscaping exemption only holds if fill stays at 15 centimetres or less at any point, drainage onto neighbouring properties is unchanged, and no swale is blocked. A patio that raises the yard significantly or redirects runoff toward a neighbour can cross that line even though the same size patio built flush with existing grade would not.

Heavy clay soil and drainage
Much of Hamilton sits on dense clay subsoil that drains more slowly than sandier soil, which means a patio base without adequate compaction and a drainage outlet can hold water against the pavers through wet spring seasons. Contractors familiar with the area typically add extra granular depth or a drainage layer specifically because of this soil, not as an upsell.

Common questions
Do I need a permit for an interlocking patio in Hamilton?
Not for a typical patio built at or near existing grade. You only need a Site Alteration Permit under By-law 19-286 if the work changes the grade of your lot beyond the landscaping exemption, for example raising the yard more than 15 centimetres at any point or changing where water drains onto a neighbouring property.
How deep does the base need to be so the patio survives Hamilton winters?
It depends on soil and drainage conditions on the specific site, which is exactly why a reputable contractor excavates and compacts a granular base well beyond what a warmer climate would need rather than quoting a fixed depth over the phone.
Can interlock pavers be installed over an existing concrete patio?
Generally no. Pavers need a properly excavated and compacted granular base underneath them to handle freeze-thaw movement, and laying them directly on top of concrete skips that base and tends to fail within a season or two.
How long does an interlock patio installation take from start to finish?
Excavation and base compaction typically take longer than laying the pavers themselves, so a mid-sized patio often runs several days to a week depending on soil conditions, access to the yard, and how much old material has to come out first.
