Richmond Hill Demolition Permit Requirements and Timeline

Yes, you need a demolition permit in Richmond Hill for any structure over 10 square metres, which is about 108 square feet. That threshold catches every house, every detached garage large enough to park a car in, and most sheds. The permit costs $250 as of 2026, and review takes two to four weeks for a complete application with all required documents. If you are tearing down a house to build a replacement estate in South Richvale or Oak Ridges, the demolition permit is the first permit in the sequence, ahead of your building permit requirements in Richmond Hill.

The City of Richmond Hill issues demolition permits through Building Services. The application requires proof of utility disconnection, a site plan showing what comes down and what stays, and in some cases an asbestos survey or heritage clearance. Most teardowns we run in Richmond Hill are 1960s to 1980s houses on lots that now justify custom home construction in Richmond Hill, where the demolition permit, the grading permit and the building permit often move through review in parallel to save calendar time.

When Richmond Hill requires a demolition permit

Richmond Hill requires a demolition permit for any building or structure with a footprint larger than 10 square metres. That includes every single-family house, every detached garage wider than about 3.3 metres, most workshops, and any accessory building that was permitted when it was built. The 10-square-metre line is set by the Building Code Act, so it applies equally across Ontario municipalities.

You also need a demolition permit for partial demolition that affects the structure: removing a bearing wall, cutting away part of a foundation, or tearing off more than half the roof framing. Interior gut work that leaves the framing standing does not trigger a separate demolition permit, but it does need a building permit before you start. The distinction matters on South Richvale lots, where some clients consider a facade-retention strategy to preserve mature trees near the house. That approach still needs both permits, plus engineered shoring.

Structures inside the Oak Ridges Moraine Conservation Plan area, which covers most of Oak Ridges and Jefferson, need the same demolition permit but may also need Lake Simcoe Region Conservation Authority screening if the lot sits near a watercourse, wetland or steep slope. We check moraine designations and conservation regulation at feasibility, because on some Jefferson lots the conservation review, not the building department, sets the approval calendar.

What structures are exempt from a demolition permit

Structures under 10 square metres do not need a demolition permit in Richmond Hill. A garden shed measuring 3 metres by 3 metres, for instance, can come down without a permit application. Fences, retaining walls under about 1 metre high, decks under 600 millimetres above grade, and detached carports or canopies smaller than the threshold are also exempt.

The exemption does not mean you can ignore other bylaws. A structure that did not need a permit to build still needs to be demolished safely, with dust control, noise limits during the hours allowed by the city, and disposal bin permits if the bin sits on the street. And if asbestos is present, provincial Regulation 278/05 under the Occupational Health and Safety Act requires abatement by a licensed contractor before demolition starts, regardless of structure size or whether a permit is involved.

How much a demolition permit costs in Richmond Hill in 2026

The demolition permit fee in Richmond Hill is $250 as of 2026. That is a flat fee for residential structures and does not scale with house size or value. The fee covers the permit review, the site inspection after demolition to confirm the foundation is capped or removed as approved, and the administrative close-out.

The $250 is the smallest line item in a teardown budget. Actual demolition of a typical Richmond Hill house runs roughly $18,000 to $35,000 depending on size, basement depth, whether the foundation comes out or gets capped for reuse, and how many trucks of rubble leave the site. A 1970s South Richvale bungalow with a full basement and an attached two-car garage typically lands near $22,000 to $28,000 for demolition, plus the bin permits, utility disconnections, and asbestos abatement if the house has vermiculite insulation or older floor tiles. On the South Richvale modern home we completed in 2024, demolition of the existing 1,800-square-foot bungalow and detached garage cost $26,400 including asbestos removal, capping the foundation for reuse, and three weeks of bin rental.

What documents you need to submit with your application

A complete demolition permit application in Richmond Hill requires a site plan showing the structure to be demolished, the lot lines, and any structures or trees that remain. The plan does not need an architect's stamp, but it must be to scale and dimensioned. If you are demolishing to build a replacement house, we usually submit the demolition application with the grading plan prepared for the building permit, which satisfies the site plan requirement and keeps both files moving in parallel.

You also need proof that all utilities serving the structure have been disconnected or will be disconnected before demolition starts: a letter or work order from Enbridge for gas, from Alectra Utilities for hydro, and confirmation that water and sanitary connections are capped at the property line. Richmond Hill will not issue the demolition permit until those confirmations are on file. For a house demolition, we coordinate the disconnection requests as soon as the permit application goes in, because Enbridge and Alectra each need roughly two to three weeks to schedule the physical disconnection.

If the house was built before 1990, the city may ask for an asbestos survey or a signed declaration that no asbestos-containing materials are present. In practice, almost every pre-1990 house in Richmond Hill contains some asbestos, most commonly in vermiculite attic insulation, vinyl floor tiles, or pipe wrap, so the survey finds it and the abatement happens before the demolition crew arrives. A survey costs roughly $800 to $1,500. Abatement for a typical bungalow runs $3,500 to $9,000 depending on what the survey finds and how much material needs removal.

How long the demolition permit review takes

Richmond Hill Building Services reviews complete demolition permit applications in two to four weeks. The Building Code Act sets a 10-business-day review deadline for houses, but the clock does not start until the application is deemed complete, which means all required documents are submitted and legible, the fee is paid, and any heritage or conservation screening is cleared. Incomplete applications sit in the queue without a running clock, which is why we submit a full package on day one.

Heritage properties and houses near Mill Pond sometimes need a heritage clearance before the demolition permit issues, even if the house itself is not designated. That review is handled by the city's Heritage Section and adds roughly two to four weeks to the timeline. Oak Ridges and Jefferson properties within the moraine plan may need Lake Simcoe Region Conservation Authority screening if the lot is regulated. That screening typically adds one to three weeks if it is required. We identify both risks at the feasibility stage, so the timeline estimate we give a client before land purchase includes the extra review steps.

Utility disconnection requirements before demolition starts

Before demolition begins, you must disconnect or cap natural gas, electrical service, water and sanitary sewer at the property line. Enbridge Gas requires a licensed gas technician to physically disconnect and cap the gas line. The work needs a TSSA certificate, and Enbridge will not remove the meter until the certificate is filed. Alectra Utilities disconnects the hydro service at the pole or the transformer after you submit a disconnection request. That service call is free but needs to be booked at least two weeks ahead.

Water and sanitary disconnection is usually handled by the demolition contractor or the plumbing subtrade preparing the site for the new house. The water curb valve is shut off, the service line is capped at the property line, and the sanitary line is plugged with a test cap that can be reopened when the new house is ready for service. Richmond Hill inspects the capped connections as part of the demolition permit close-out, so the caps must meet the plumbing code even though the house is gone.

We coordinate all four disconnections before the demolition crew mobilizes. A gas line left live or a hydro service still connected is a safety hazard and a permit violation that stops the job. On most Richmond Hill teardowns, the gas and hydro disconnections happen in the same week the demolition permit is issued, and the demo crew arrives two or three days after the last utility confirms disconnection.

What happens if you demolish without a permit in Richmond Hill

Demolishing a structure over 10 square metres without a permit in Richmond Hill is a Building Code Act offence. The city can issue a stop-work order, which halts all work on the property including any construction planned for the replacement house. The fine for proceeding without a permit can reach several thousand dollars for a first offence, and each day the violation continues can be charged as a separate count.

More costly than the fine is the delay to your building permit. If the demolition happened without inspection, Richmond Hill may require an engineer's report confirming that the foundation, if it remains, is sound and that no debris or contaminants were buried on site. That report costs $4,000 to $8,000 and takes two to four weeks to prepare, and the building permit will not issue until it is submitted and reviewed. On a custom home project with a construction loan or a closing date tied to selling another house, that delay costs real money.

We have been called to projects where a homeowner hired a demolition contractor who promised to handle the permits and then did not. The contractor disappeared, the city issued a stop-work, and the building permit application sat frozen until an engineer certified the site. The $250 permit fee would have prevented all of it. If you are planning a replacement home in Richmond Hill, make the demolition permit the first line item in the budget and the first application in the sequence. It protects the schedule, it protects the budget, and it keeps the building department cooperative when the larger permits arrive.
