Excavation, Grading & Construction Contractor in Richmond Hill, ON

Richmond Hill is home base for OCM Excavation & Construction. Owner Ofer Hadad lives and works here, and our trucks are parked here every night — which means Richmond Hill clients almost always get same-day or next-day on-site visits. We’ve dug, graded and built across the entire city, from the mature streets south of Major Mackenzie, up through Bayview Hill, Mill Pond, Jefferson, Oak Ridges, and the rural acreages north of Stouffville Road. If you’ve driven past an excavation site behind a Richmond Hill home in the past few years, there’s a good chance it was one of ours.

Local Knowledge: Richmond Hill Permits & Conditions

Site Alteration & Lot Grading Bylaw

Richmond Hill enforces a site-alteration and lot-grading bylaw on most residential lots. Before any major dig, regrade or fill import we file the lot-grading plan with the Richmond Hill building department and book the pre-pour and final-grade inspections so your deposit gets released on schedule.

Tree Preservation & Protection

Richmond Hill protects mature trees on private and boulevard lots. We assess the tree-protection zone before mobilising, install snow-fence hoarding where required, and coordinate with the city arborist on any work inside the drip line so you avoid surprise stop-work orders mid-dig.

Conservation Authority Setbacks

Lots near rivers, ravines or wetlands in Richmond Hill fall inside the Toronto and Region Conservation Authority (TRCA) regulated area. We flag this on the quote, prepare the permit package and engineering letters, and stage the dig so the inspector signs off the first time — no two-week resubmission delays.

All Richmond Hill permits route through the Richmond Hill Municipal Offices at 225 East Beaver Creek Road (Building Permits Counter). Foundation, pool, deck-over-2′-grade, walk-up basement and septic work require a permit reviewed under the Ontario Building Code 2024. Importantly, Richmond Hill enforces a Site Alteration Bylaw separately from the building permit — moving, importing or exporting more than 30 cubic metres of soil in a single property requires its own Site Alteration Permit, regardless of whether you’re building anything. OCM has filed dozens of these and knows the geotechnical and drainage-plan inputs reviewers expect.

Soil and groundwater conditions in Richmond Hill are some of the most variable in the GTA. South of Elgin Mills you’ll find dense glacial till — slow to excavate but stable in deep cuts. Oak Ridges and Jefferson sit on the Oak Ridges Moraine, with sandy, highly permeable soils and shallow water tables that demand careful dewatering and almost always trigger the Lake Simcoe Region Conservation Authority (LSRCA) or TRCA permit process. Bayview Hill and Mill Pond often have older clay-tile drainage that needs upgrading whenever a basement entrance is added. Common Richmond Hill jobs for us: inground pool excavations in Bayview Hill, full-property regrading in Westbrook, and rural septic installs north of Bloomington Road. Because we live here, we genuinely care about leaving your street as we found it — no mud tracked four blocks down Yonge.

Richmond Hill Excavation FAQ

Do I need a permit to excavate in Richmond Hill?

Yes for most digs. Richmond Hill requires a building permit any time you excavate deeper than 1.2 m for footings, a pool, a walk-up basement or an addition — applications go through Richmond Hill Municipal Offices. Site-alteration and lot-grading bylaws also apply: most new builds and major regrades require a grading certificate signed by an Ontario Land Surveyor or P.Eng before the city releases your deposit. OCM files the permit, books the inspections and coordinates with Toronto and Region Conservation Authority (TRCA) when your lot is inside a regulated area.

How much does excavation cost in Richmond Hill in 2026?

Most Richmond Hill residential excavation jobs land between $3,500 and $25,000, depending on volume and access. A 16×32 pool dig is typically $9,000–$14,000; a foundation hole for a 2-storey addition runs $6,500–$12,000; a single-side walk-up basement runs $14,000–$24,000 with shoring. Costs rise with deeper digs, tight rear-yard access requiring a smaller machine, hauling soil offsite, or hitting groundwater. Every OCM quote is itemised: machine time, trucking, disposal, permit fees and restoration — call 416-317-3090 for a free site visit.

How long does a typical residential excavation take in Richmond Hill?

Most Richmond Hill residential digs finish in 1–5 working days on site. A standard 30×50 foundation hole is usually 1–2 days of machine time. A rear-yard pool excavation is 2–3 days including soil haul-away. Walk-up basement entrances take 4–7 days because of underpinning, structural steel and concrete pouring. The full project clock is longer because of permitting (2–6 weeks) and Toronto and Region Conservation Authority (TRCA) review when applicable. OCM books a site visit within 48 hours and gives you a written start-to-finish schedule before any dig begins.

What soil conditions are common in Richmond Hill and how do they affect cost?

Richmond Hill soil varies block to block. Older neighbourhoods like Bayview Hill often sit on dense clay till with seasonal high water tables — that means trench-box shoring past 1.5 m and slower digging. Newer subdivisions like Oak Ridges are often built on engineered fill that's looser but mixed with debris. Lots near rivers, ravines or the Toronto and Region Conservation Authority (TRCA) regulated area can hit groundwater that needs a dewatering pump on site. OCM's site visit always includes a hand-dig test pit so the quote reflects real soil — no surprise change orders mid-project.
