Key takeaways
- The City's development charge on one new single detached unit runs from $44,415 in the rural area to $102,451 in Urban Area A on separated sewers. Where the lot sits decides the number, not the size of the house.
- Four conservation authorities have jurisdiction inside Hamilton. Which one governs your property follows the watershed, not the ward.
- A building permit for a detached house is priced at $18.32 per square metre of floor area. Per square metre, not per square foot.
- One Building Division issues building permits for all six former municipalities, but residential zoning in parts of Hamilton is still governed by the former community's by-law.
- The price of a listed model covers the structure and delivery. Turnkey finishing, foundation, site preparation, servicing, permits and municipal charges are quoted separately against your lot.
What does the City of Hamilton charge to build one new house?
The City collects development charges under City of Hamilton Development Charges By-law 24-072. The rate depends on the dwelling type and on which servicing area the lot falls in. It does not depend on how large the house is.
How much are Hamilton's development charges on a single detached dwelling?
For a single or semi-detached unit, the full City rate in effect from 1 June 2026 to 31 May 2027 is set out in the City's development charges pamphlet for the current rate year:
| Servicing area | City development charge, single or semi-detached ($ per unit) |
|---|---|
| Rural Area | $44,415 |
| Urban Area A — combined sewer system | $89,729 |
| Urban Area A — separated sewer system | $102,451 |
| Urban Area B — separated sewer system | $81,303 |
All four rates are stated per unit, not per square foot or per square metre.
These are the full rates. Two partial exemptions currently reduce what is actually payable: a 20% partial exemption running 1 September 2025 to 31 August 2027, and a 4% partial exemption running 1 June 2026 to 31 May 2027. The City calculates the net figure. Do not assume a number off this table is what you will write the cheque for.
Education development charges add $3,579 per unit. They are set by the Hamilton-Wentworth District School Board and the Hamilton-Wentworth Catholic District School Board and collected by the City on their behalf, and City exemption policies do not touch them. Land inside the Dundas and Waterdown special area carries a further $1,931 per unit. Parkland dedication is a separate instrument again.
Why the rural development charge is less than half the urban rate
A rural lot pays the municipal-wide soft and hard services component only. An urban lot pays that plus water, wastewater and stormwater.
That is the entire difference, and it is worth $58,036 per unit between the rural rate and the Urban Area A separated-sewer rate.
It is settled before anyone draws anything, and it is why two Hamilton lots twenty minutes apart produce quotes that look impossible to reconcile.
What does a Hamilton building permit cost for a new house?
Building permits in Hamilton are priced by floor area. Under City of Hamilton Building By-law 15-058, as replaced by the 2025 schedule of permit fees, the service index for a detached house is $18.32 per square metre.
Read that unit carefully. Per square metre, not per square foot — mistaking one for the other understates the fee tenfold, and you find out at the counter. A 200-square-metre house, about 2,153 square feet, works out to roughly $3,664 at that rate. The minimum fee for any permit is $291.
Several other permits attach to the same residential construction project:
| Permit type | Flat fee under the current schedule |
|---|---|
| Foundation permit, residential under Part 9 | $453 |
| New water service, filed with the building permit application | $168 |
| New sewer service, filed with the building permit application | $168 |
| Sewage system, new construction | $1,010 |
| Sewage system, Class 5 or repair | $619 |
None of these sit inside a model price. They are municipal charges, quoted and paid separately.
You now know the range. What you need is the number for your own address — which servicing area the lot falls in, and what that does to your budget.
Which conservation authority has jurisdiction over your Hamilton lot?
Four conservation authorities have jurisdiction inside the City of Hamilton. This is unusual, and it catches people who assume one city means one authority.
The four conservation authorities inside one city
City staff met with all four in March 2024 to work through the regulatory changes: the Hamilton Conservation Authority, the Niagara Peninsula Conservation Authority, the Grand River Conservation Authority, and Conservation Halton. The City recorded this in a communication update to Council on the Conservation Authorities Act dated 5 April 2024.
Boundaries follow watersheds. They do not follow wards, former municipal lines, or anything visible from the road. Two neighbours can answer to different authorities.
When do you need a conservation authority permit as well as building permits?
Since 1 April 2024 a single provincial regulation, O. Reg. 41/24, has replaced the 36 individual conservation authority regulations. Under it the regulated area around a wetland is 30 metres, reduced from the previous 120 metres for provincially significant wetlands.
A conservation authority permit is separate from your building permit. One does not substitute for the other, and the conservation authority permit generally has to clear first.
How long does a conservation authority decision take?
O. Reg. 41/24 set service standards. The authority has 21 days to confirm whether your application is complete, and 90 days from that point to decide. If no decision arrives inside 90 days, the applicant can appeal to the Ontario Land Tribunal.
Those are the outer limits, not a schedule. The City also retains its own Official Plan policies and zoning regardless of what the conservation authority does, and can still require an Environmental Impact Study on land outside the 30-metre buffer. A lot can clear the conservation authority and still face a City study requirement, so find out which authority you are dealing with before you make an offer on land.
Where do you apply for a building permit in Hamilton?
One Building Division for all six former municipalities
Hamilton amalgamated the former City of Hamilton, the Town of Ancaster, the Town of Dundas, the Town of Flamborough, the Township of Glanbrook and the City of Stoney Creek. Building permits for all of them are issued by the City of Hamilton Building Division at 71 Main Street West.
Former city
HamiltonTown
AncasterTown
DundasTown
FlamboroughTownship
GlanbrookCity
Stoney CreekYou apply in one place whether the lot is in Waterdown or on Barton Street. That part is simple.
Which zoning by-law governs your Hamilton lot?
Zoning is not simple. City-wide Zoning By-law No. 05-200 came into effect on 25 May 2005 and has been implemented in stages ever since, progressively replacing the by-laws of the six former municipalities.
The City's current position on zoning is that for most properties in the former municipalities, zoning is regulated by By-law 05-200 — but the residential zones are regulated by the by-laws of each former community.
| Where your lot sits | Which by-law governs the residential zone |
|---|---|
| Rural area, city-wide | By-law 05-200, Section 12 (Rural Zones) |
| Urban area, low-density residential | By-law 05-200 low-density residential zones, introduced 2022 |
| Urban area under a secondary plan | The former community's by-law — including Hamilton 6593, Ancaster 87-57 and Dundas 3581-86 |
Confirm which by-law governs your lot before you assume a setback, a height or a lot coverage number. Getting this wrong is a redesign, not a correction.
What rural zoning allows for a single detached dwelling
Here is the counterintuitive part: rural zoning was folded into the city-wide by-law before urban residential zoning was. The numbers that decide what will physically fit on a rural lot are identical in both rural zones — the Agriculture (A1) Zone at Section 12.1.3.3 and the Rural (A2) Zone at Section 12.2.3.7.
| Zoning regulation | Requirement for a single detached dwelling |
|---|---|
| Minimum lot area | 0.4 hectares |
| Minimum lot width | 30.0 metres |
| Maximum building height | 10.5 metres |
| Minimum front yard | 10.0 metres |
| Minimum side yard | 3.0 metres |
| Minimum rear yard | 10.0 metres |
The 0.4-hectare minimum is roughly one acre, and it applies to the dwelling. Agricultural uses in the same zones carry a 40.4-hectare minimum. A parcel can be far too small to farm and still large enough to build a house on.
In the urban area the direction of travel has been toward more units on the same land. In February 2024 the City permitted triplexes and fourplexes in low-density residential zones, and on 8 October 2025 Council approved new mid-rise residential zones city-wide.
Which by-law governs your lot decides your setbacks, your height and your lot coverage. Bring the address and we will confirm it before you commit to a design.
Where in Hamilton does My Own Cottage build custom homes?
Which Hamilton communities we deliver to
My Own Cottage Inc. delivers anywhere in Ontario, and Hamilton sits comfortably inside that. That covers the lower city and the Mountain, Ancaster, Dundas, Waterdown and Flamborough, Stoney Creek, and Glanbrook — including Binbrook, Mount Hope, Carlisle, Freelton and Greensville.
Including
Binbrook·Mount Hope·Carlisle·Freelton·GreensvilleThe build happens at our facility at 12 Lankin Blvd #3, Orillia, ON L3V 7B6. What arrives on your Hamilton lot is the finished structure.
What the price of a listed model covers
A listed model price covers the structure and delivery. That is the whole of it.
Turnkey finishing, foundation, site preparation, servicing, permits and municipal charges sit outside that number and are quoted separately against your specific lot. Development charges, education development charges and building permit fees are all in that second category, which is why the figures earlier on this page matter more to your budget than the model you choose.
Who builds on your Hamilton lot
Everything that happens on the ground in Hamilton — foundation, site preparation, servicing — is carried out by licensed-trade installation professionals. They are contracted, not employees.
Their work is quoted separately against your lot and set in the agreement before the build starts. You see that number before you commit, not after. We also help with municipal permits.
Most of what decides your Hamilton budget is on the lot, not in the model. Bring the address and we will work through the charges, the authority and the by-law together.
What has to be approved on a Hamilton lot with no municipal water or sewer?
Who approves a septic system in Hamilton?
The City of Hamilton Building Division administers private on-site sewage systems, from City Hall, 3rd Floor, 71 Main Street West. Not the conservation authority, and not Public Health.
A permit for a new sewage system costs $1,010, flat. A Class 5 system or a repair costs $619, and the maintenance inspection program fee is $283. These are flat fees — unlike the building permit itself, they do not scale with floor area. The City also runs a septic system inspection program tied to source water protection, under which existing private systems are inspected on a cycle.
What the Rural Hamilton Official Plan requires of a rural applicant
The Rural Hamilton Official Plan was adopted by By-law 06-295 on 27 September 2006, approved by the Ministry of Municipal Affairs and Housing on 13 March 2011, and approved by the Ontario Municipal Board on 7 March 2012. It has been amended many times since.
Its Section C.5 servicing policies govern rural lots. A rural applicant has to demonstrate a sustainable private well and a sustainable private sewage disposal system. The Plan uses "sustainable" as a test to be satisfied, not as a description.
What a private-services lot needs before a building permit
The order matters. Servicing has to be demonstrated before the dwelling is approved, not alongside it.
Zoning gives you a 0.4-hectare floor. Servicing can raise it. A lot that cannot carry a septic bed and a well at the required separations is not a lot you can put a principal dwelling on, whatever the zoning map says.
Can a factory-built home reach your Hamilton lot?
Do you need a permit for home delivery on a Hamilton street?
Sometimes, and there are two of them. Short-term occupancy of a lane or a sidewalk requires a Temporary Lane and Sidewalk Occupancy Permit. Blocking a full roadway, or one full direction of traffic, for more than three to five minutes requires a Temporary Road Closure Permit. Both are set out on the City's page for temporary permits covering lanes, sidewalks and road closures.
| Occupancy type | Fee | Charged on this basis |
|---|---|---|
| Unrestricted lane occupancy | $61.30 | Per 14-day period |
| Restricted lane occupancy, on an arterial signed No Parking or No Stopping Anytime | $61.30 | Per lane, per day |
| Sidewalk closure | $132.80 | Per 14-day period |
The City asks for a minimum of five days' notice. Note the unit difference in the middle row — restricted lane occupancy is charged daily, not per fortnight, so a delivery onto a busy arterial is priced differently from the same delivery onto a residential street.
What a lower-city lot on the LRT corridor adds
If your lot sits along the future Hamilton LRT, you may need a Corridor Development Permit from Metrolinx under the Building Transit Faster Act, 2020 before you can apply for the City's occupancy permit.
That is a sequencing problem rather than a cost problem. It is the kind of thing worth establishing in week one rather than week twelve.
Getting a driveway approved on a rural Hamilton road
If the lot has no driveway yet, or the existing one has to be widened, you need City approval before anything crosses the municipal boulevard. The driveway access application goes to Transportation Planning and Parking and carries a non-refundable fee of $489 including HST. Construction of the approach ramp is billed on top of that.
The same application covers a new driveway with a culvert, which is the usual case on a rural road. City standards allow a single approach of 2.7 to 3.6 metres and a double of 5.4 to 6.1 metres, measured on City property.
One thing to be clear about: approving the access says nothing about whether your land use conforms to the zoning. Those are two separate determinations and you need both.
Charges, jurisdiction, servicing and access all resolve differently on every lot. Once you know what yours allows, the next question is what fits on it.
What Hamilton custom home builders cannot change about your lot
The City's charges are the same whoever builds
Prefab homes, modular homes and factory-built homes are three names for the same thing — a house assembled off-site and delivered to your land. The City of Hamilton does not price any of them differently from traditional homes built on site.
Development charges, education development charges, special area charges, building permits and conservation authority permits attach to the lot and the dwelling. They do not move based on who signs the contract. Any quote that appears to beat another by the size of a development charge is either excluding it or has a lot in a different servicing area. Ask which.
What every builder still has to do on site
Foundation, site preparation and servicing happen on your Hamilton lot regardless of where the house was assembled. With My Own Cottage those are quoted separately by licensed trades and set in the agreement before the build. With a local design-build firm they sit inside a single contract and a single number.
Neither arrangement removes the work, and neither removes the municipal charges. The useful comparison between a design-build contract and a factory-built one is not the headline figure — it is what each figure includes. Ask both for the same line items and the numbers become comparable.

Book the consultation before you commit to a Hamilton lot
Hamilton custom home builders are all working from the same zoning by-law, the same four conservation authorities and the same development charge schedule. What separates a workable budget from a stalled one is finding out which of those apply to your specific address, early enough to matter.
Bring the address. We will tell you which servicing area it falls in, which conservation authority has jurisdiction, and which zoning by-law governs it. Free, no obligation. If a factory-built path turns out to be wrong for that lot, we will say so.
