Deck Building in King City & Across King Township

OCM Excavation & Construction builds custom decks across King City, Nobleton, Schomberg, and Kettleby. We have been working King Township estate lots since 2008 — multi-level wraparounds, pool decks tied into Fence By-law 2012-132 enclosures, and raised structures on ORM and Greenbelt land where the rules tighten. Call 416-317-3090 to book a site visit. We pull the Township of King building permit, locate well and septic before any footing goes in, and frame to the 1.2 m frost depth the Ontario Building Code requires this far north.

Why deck building in King City is different

King City is not the suburbs. The Township of King governs differently from Vaughan or Richmond Hill, and the lots reflect that — 1 to 5 acres is normal, 10+ acres is common in the equestrian belt north of 15th Sideroad. That changes the deck conversation in five concrete ways.

• Township governance, not city — building permits go through the Township of King Building Division, not a regional one-stop counter. Drawings and lot grading expectations are reviewed against rural standards.
• Estate-lot scale — a 600 sq ft deck is small here. Most King City builds we quote run multi-level, wraparound, or main-deck-plus-pool-deck configurations because the homes and the views support it.
• ORM and Greenbelt overlays — large parts of King Township sit inside the Oak Ridges Moraine Conservation Plan area and Greenbelt. ORM Area Zoning By-law 2005-23 governs setbacks, permeable cover, and vegetation removal. Paver-base or stamped-concrete deck transitions get reviewed against impermeable-surface limits.
• Heritage in the King City core — properties inside the King City Heritage Conservation District face extra design review for visible additions. We confirm heritage status before drafting plans.
• Well, septic, and conservation — every estate lot has a private well and septic field. Footing layout has to clear both. TRCA covers south King, LSRCA covers north King — if the deck sits within a regulated area, a CA permit precedes the building permit.

Where we build across King Township

• King City core — Keele, King Road, Dufferin frontage. Mature lots, some inside the Heritage Conservation District.
• Nobleton — west King, custom builds along Highway 27 and the side roads. Many lots on private well/septic.
• Schomberg — north Township, mix of village lots and rural estate parcels.
• Kettleby — small village character, surrounded by ORM-regulated countryside.
• ORM countryside and equestrian belt — 15th Sideroad, 16th Sideroad, Weston Road, Jane Street north of King Road. Acreage builds where deck footprints often exceed 1,000 sq ft.

Types of decks we build in King City

• Single-level decks — straightforward attached or freestanding builds, pressure-treated or cedar framing, composite or PT decking.
• Multi-level decks — common on King Township estate lots where the walk-out grade drops 4 to 8 feet from the main floor. Stepped platforms tie the upper deck to a lower patio or pool surround.
• Pool decks — integrated with the pool enclosure under King Township Fence By-law 2012-132. We frame the deck so the 1.2 m enclosure fence, gates, and self-closing hardware satisfy the by-law before pool inspection.
• Wraparound decks — estate-scale builds wrapping two or three elevations of the house, often 800 to 1,500+ sq ft.
• Raised decks with under-deck storage — common on walk-out lots where the under-deck space becomes covered patio or equipment storage.
• Material mix — pressure-treated framing standard, cedar for visible structure, composite (Trex, TimberTech) or hardwood decking, aluminum or glass railing for sightlines on rural properties.

Our deck building process in King Township

1. Site visit and quote — we walk the lot, confirm grade, locate well head and septic bed, flag any ORM/Greenbelt or CA regulated lands.
2. Drawings and permit — Township of King building permits are required for decks attached to a dwelling more than 600 mm (2 ft) above grade or larger than 10 sq m. We prepare plans, site plan, and lot grading detail.
3. Conservation authority check — if the deck sits in TRCA or LSRCA regulated area, we file for the CA permit before the building permit goes final.
4. Ontario One Call locate — gas, hydro, telecom marked. On rural King City lots we add a private locate for well lines and septic components.
5. Sonotube footings — augured to 1.2 m minimum frost depth per the Ontario Building Code, bell-bottomed where soil bearing requires.
6. Framing — pressure-treated ledger lag-bolted with flashing, joists at 16 in. on centre (12 in. for composite), double rim, hurricane ties.
7. Decking, railing, stairs — boards laid, picture-frame border where specified, code-compliant railing at 36 in. residential or 42 in. where the walking surface exceeds 1.8 m above grade.
8. Final inspection — Township building inspector signs off; pool enclosure inspection follows if the deck integrates with a pool.

What affects deck cost in King City

• Square footage — estate-scale King Township decks routinely run 600 to 1,500+ sq ft, well above the suburban 200-400 sq ft average.
• Height and levels — multi-level builds need more footings, more rim joist, more stairs, more railing.
• Material — pressure-treated is the floor; cedar, composite, and hardwood each add to the linear-foot cost.
• Footing count — sonotube count drives labour and concrete. Soft or organic soil on ORM lots sometimes requires bell-bottom or helical piles.
• Township permit fees — Building Division fees scale with deck area.
• ORM, Greenbelt, or CA permits — if the lot is regulated, add review time and permit cost. TRCA and LSRCA both charge by complexity.
• Well or septic conflict — if the planned footing pattern clashes with a septic bed, the layout changes or the bed gets a relocation cost added.
• Access — long driveways and gated estate properties affect material delivery and disposal.

FAQ — deck building in King City

Do I need a building permit for a deck in King Township?

Yes, if the deck is attached to your dwelling and rises more than 600 mm (2 ft) above grade, or if the deck is larger than 10 sq m. The Township of King Building Division issues the permit. We prepare drawings, site plan, and lot grading detail and submit through the King CityView portal.

Does ORM or Greenbelt status change what I can build?

It can. Large parts of King Township sit inside the Oak Ridges Moraine Conservation Plan area, governed by ORM Area Zoning By-law 2005-23. Permeable-cover rules, vegetation setbacks, and added review apply. We confirm ORM and Greenbelt status from the survey and Township mapping before we draw plans.

How deep do deck footings go in King City?

Sonotube footings are augered to 1.2 m minimum to clear frost depth under the Ontario Building Code. On organic or low-bearing soil — which we see on some ORM and Holland Marsh-adjacent lots — we bell-bottom the base or switch to helical piles to hit bearing.

Can you build a deck around a pool on a King Township lot?

Yes. We frame pool decks so the enclosure required by King Township Fence By-law 2012-132 — fence height, self-closing gates, hardware — is integrated rather than bolted on after. The Township pool enclosure inspection runs after the deck and fence are complete.
