Modular Homes & Garden Suites in Township of Madoc, Ontario
Factory-direct modular homes and backyard suites for the Township of Madoc — the rural township north and west of the village, taking in Eldorado, Bannockburn and Cooper. ⚠️ Not the same municipality as the village of Madoc, which has been part of Centre Hastings since 1998 and has quite different rules. Here in the Township, By-law 1431-2017 permits a second dwelling unit as-of-right on a well-and-septic lot, with NO maximum size — here's what it allows, what it costs, and the one question worth asking before you order.
What you can build in Township of Madoc
Full modular homes — from $175,696. 29 models from 560 to 1,405 sq ft, 1–3 bedrooms — factory-built to the Ontario Building Code and set on a permanent foundation (a real, permanent house, not a “trailer”).
Backyard suites (ADUs) — from $96,244. 7 compact models built for garden-suite and in-law-suite use, sized to fit what Township of Madoc's by-law allows.
All homes are CSA-certified (A277 modular / Z240MH manufactured), finished in the factory, and delivered ready for foundation and hook-up. What's the difference between modular, manufactured, and mobile? →

1 · Who's it for?
2 · What layout?
3 · What size feels right? (Township of Madoc lots typically allow up to ~1,200 sq ft)
The Township sets no maximum size for a second dwelling unit. All accessory buildings together may cover 10% of the lot, which on a 2-acre rural lot is roughly 800 m² (≈8,600 sq ft) of allowance — so a full-size home is genuinely in play, and setbacks and septic capacity are the real limits. Enter your address for the specifics. Your exact lot may allow more or less — get the real number for your address in seconds.

Often, yes — Township of Madoc permits a detached Additional Residential Unit on most serviced residential lots. The specifics, from Township of Madoc Comprehensive Zoning By-law 1072-2002, §5.19.1 — Second Dwelling Units (added by amending By-law 1431-2017; a standalone amendment that is NOT merged into the posted September 2008 office consolidation):
| Max size | No maximum. §5.19.1 sets no floor-area cap at all — the governing limit is that all accessory buildings on the lot together may cover at most 10% of the lot. On a 1-acre lot that is about 400 m² (≈4,300 sq ft) of allowance, so the by-law is rarely what limits you. |
|---|---|
| ⚠️ Minimum size | Worth settling BEFORE you order a compact model. The Rural Residential zone sets a MINIMUM gross floor area of 74.3 m² (800 sq ft) for a dwelling, and §5.19.1 sends a detached unit to the principal-building requirements of its zone — but the township-wide minimum-size table (§5.50) has no line for a second dwelling unit, because it predates the 2017 amendment. We read it as applying; Hastings County planning can confirm in one call. If it does apply, studio-sized units are out here. |
| Where it goes | Permitted in the Rural (RU), Rural Residential (RR), Waterfront Residential (WR), Residential First Density (R1), Residential Second Density (R2) and Multiple Residential (MR) zones — inside your existing house OR in a detached building, but not both, and only ONE second unit per lot. Private-road and water-access lots are zoned Limited Service Residential, which is not on that list. |
| Height & setbacks | A detached unit follows the PRINCIPAL-building standards of your zone, not the smaller accessory-building ones. In Rural Residential that is a 20 m (≈66 ft) front yard, 10 m (≈33 ft) rear, 3 m (≈10 ft) interior side and 20 m exterior side; in the Rural zone the interior side is 8 m (≈26 ft). Maximum height 11 m (≈36 ft), and at least 3 m (≈10 ft) from the main house. |
| Parking | 1 space, for the exclusive use of the second unit’s occupants |
| Servicing | The Township has no municipal water or sewer anywhere — every lot is a private well and septic, so septic capacity is the gate. Helpfully, Madoc issues its own septic permits through the joint Building Inspection Service Board using the same Cloudpermit application as the building permit, so it is one desk rather than two. |
| Conservation | Quinte Conservation covers the entire Township (Moira / Skootamatta watershed). No building, structure or septic bed within 30 m (≈98 ft) of the high-water mark of a waterbody or permanent watercourse, 15 m (≈49 ft) of a top of bank, or 30 m of an Environmental Protection Wetland zone. A proposal within 300 m of Eldorado, Jarvis, Hazzard or Banker Lake should carry a cold-water Lake Capacity Study. |
Getting your building permit in Township of Madoc
An eligible lot still needs a building permit before anything is delivered. Here's how Township of Madoc's process actually works — verified against the Township of Madoc building department's own pages.
How do you apply for an ADU building permit in Township of Madoc?
Through Cloudpermit — building, plumbing and septic permits all go through the same online portal (application portal ↗). Building services for Madoc Township are delivered by a joint Building Inspection Service Board (BISB) shared with Stirling-Rawdon, Tyendinaga, Deseronto, Tweed and Marmora and Lake, and administered out of Stirling-Rawdon. Applications are created and paid for online in Cloudpermit, and inspections are booked there too — but Building staff are physically in the Madoc Township office (15651 Highway 62) only on WEDNESDAYS 1:00–4:00 pm, so plan any in-person conversation around that window. The contact and inspection line is 1-866-414-0088 (or 613-395-5166). Township of Madoc's building-permit page ↗
- Confirm your zone first — a second dwelling unit is only permitted in the RU, RR, WR, R1, R2 and MR zones, and the Township's own note is explicit that the proposed USE must conform to the Zoning By-law before a permit can be issued
- ⚠️ Make sure whoever reviews your file is applying By-law 1431-2017. The second-unit permission is a standalone 2017 amendment that has NOT been merged into the posted 2008 office consolidation, so the RU and RR sections as published online don't mention second units at all
- Check whether Quinte Conservation regulates your part of the lot (watercourse, wetland, steep slope or floodplain) — their approval is a prerequisite, not a parallel step, and the site drawing has to show it
- Get your septic sorted: a new or altered system needs its own permit, applied for through the SAME Cloudpermit application by choosing the 'Sewage System' category — not 'Residential Building'. A second unit on an existing system needs that system shown to have capacity
- Get an Entrance Permit signed by the Road Superintendent if the unit needs a new or altered driveway entrance
- Complete the Minimum Distance Separation (MDS) form where there is a nearby livestock operation
- Register for Cloudpermit, create the application, and attach two complete sets of scaled construction drawings plus the site plan and schedules
- Pay the fees — all applicable fees must be paid before the permit is issued
- Book inspections through Cloudpermit or on 1-866-414-0088 as construction proceeds; the BISB inspects within 48 hours of its working schedule. A permit can be revoked if required inspections aren't completed
What does a Township of Madoc ADU permit application need?
- Fully completed BISB Building Permit Application (the joint six-municipality form)
- Two complete sets of scaled construction drawings — foundation plans, floor plans, roof plan, building sections, wall sections and any engineered systems designs
- Site drawing showing the location of the building on the lot with front, side and rear yard setbacks, plus MDS reports and conservation-authority approvals where applicable
- Proof of ownership — a copy of the registered deed where the Township hasn't yet been notified of a change in ownership
- Signed Schedule 1 (Designer Information) for whoever takes responsibility for the design
- Schedule 2 signed, with the septic design, where a sewage system is being installed or altered
- Roof truss drawings stamped by a P.Eng, and stamped engineer's or architect's drawings, where applicable
- Energy efficiency design documentation — SB-12 prescriptive or performance, Energy Star or EnerGuide 80, plus duct design
- Heat loss calculations where applicable
- Well report (water source) for a new dwelling
- Entrance Permit signed by the Road Superintendent and the property owner, where applicable
- Plumbing design, at the Chief Building Official's request
How much does an ADU building permit cost in Township of Madoc?
⚠️ Madoc Township does not publish a building or septic fee schedule online, so NO dollar figures are given here — anything you are quoted should be treated as an estimate until you have it in writing from the Building Department. The Township states only that building and plumbing permit fee revenue covers the full cost of the service, with any surplus reserved for future Building Section use. Confirm current figures on 613-473-2677 (Wednesdays 1:00–4:00 pm) or 1-866-414-0088.
| Building permit — second dwelling unit | Not published. ⚠️ Do NOT assume Stirling-Rawdon's building fee by-law applies: the Building Inspection Service Board is a shared SERVICE administered out of Stirling-Rawdon, but each member municipality sets its own fees, and no Madoc-specific fee by-law is posted. Note the BISB's own permit list expressly includes 'to construct any secondary residence', so a backyard unit is unambiguously permit-triggering. |
|---|---|
| Septic permit (new or altered system) | Not published. Issued by the Township itself through the same Cloudpermit application under the 'Sewage System' category — this is one desk, not two, and no health-unit permit is involved. |
| Starting work without a permit | This one IS published as a rule rather than an amount: construction started before the permit is issued attracts an administration fee of DOUBLE the permit fee, possible fines under the Set Fines By-law, and a Stop Work Order against the construction until a permit is obtained. |
| Development charges | Collected by the Building Section when the permit is issued. No Madoc-specific rate is published, and the Township and Hastings County figures should be confirmed in writing. ⚠️ The ~$27,000-per-unit development charge widely reported for this area in 2026 belongs to CENTRE HASTINGS — a different municipality — and must not be applied to a Madoc Township lot. |
Whether Bill 23's additional-residential-unit development-charge exemption is applied here could not be verified — neither a Township nor a County DC by-law is published in a form that resolves it. Confirm before assuming the unit is exempt.
How long does an ADU building permit take in Township of Madoc?
Ontario's Building Code requires a decision on a complete house-class application within 10 business days. The BISB publishes its own service commitment: a minimum of 5 days for decks and garages, 10 working days for house permits, and 30 working days for commercial or septic permits; residential applications are issued or denied within 10 working days and multi-residential or commercial within 30. That aligns with the Ontario Building Code's 10-business-day house-class window, which only starts once the application is complete. Inspections are carried out within 48 hours of the BISB working schedule.
Registration: No separate ongoing registration or licensing regime for a second dwelling unit is published — the building permit is the approval. Planning matters, however, are no longer handled at the Township: Madoc joined Hastings County's SPARC shared-planning program on 2 July 2025, so any minor variance, rezoning or consent goes to the County (613-966-1311) and is paid for under the County's fee by-law, while the building and septic permits stay with the Township's Chief Building Official.
Worth knowing before you apply
- Building staff are in the Madoc Township office only on WEDNESDAYS 1:00–4:00 pm. Everything else runs through Cloudpermit or the toll-free line, 1-866-414-0088.
- When applying for the septic, choose the 'Sewage System' category in Cloudpermit — NOT 'Residential Building'. The Township calls this out specifically because people get it wrong and can't submit.
- ⚠️ The permission for your unit is in a standalone amendment (By-law 1431-2017), not in the zoning by-law consolidation posted online — that consolidation stops at September 2008. Have the amendment to hand if a reviewer, lender or appraiser tells you second units aren't permitted.
- The by-law sends a detached second unit to the PRINCIPAL-building setbacks of your zone, not the smaller accessory-building setbacks — so the site drawing has to show the bigger numbers (in RR: 20 m front, 10 m rear, 3 m interior side).
- A storage building under 160 sq ft doesn't need a permit, but it still has to meet the Zoning By-law setbacks — and it still counts toward the 10% accessory-building lot coverage that caps your unit.
- The BISB flyer lists three conservation authorities (Quinte, Lower Trent Valley and Crowe Valley) because it serves six municipalities. For a Madoc Township lot it is Quinte Conservation — confirmed by intersecting the County's own conservation-authority boundary layer against the full Township boundary.
- An Entrance Permit signed by the Road Superintendent is a separate item from the building permit, and the new unit will need a civic address.

Grants & financing in Township of Madoc
Building and septic permits — fees not published — The Township does not publish a building or septic fee schedule online, so we quote no figure. Confirm with the Building Department on 613-473-2677 (staff are in the Madoc office Wednesdays 1:00–4:00 pm) or 1-866-414-0088. Note that building services are shared with five neighbouring municipalities through the Building Inspection Service Board, but each sets its own fees — a figure from Stirling-Rawdon does not apply here.
Development charges — confirm before budgeting — No Madoc-specific development charge rate is published. ⚠️ Be careful with figures you find online: the roughly $27,000-per-unit charge widely reported for this area in 2026 belongs to CENTRE HASTINGS, a different municipality, and does not apply to a Township of Madoc lot.

Township of Madoc modular homes — FAQ
Is the Township of Madoc the same as the village of Madoc?
No — and this catches people out, because both share the Madoc post office and even the same postal code. The Township of Madoc is a separate municipality covering the rural land north and west of the village, with its own office on Highway 62 near Eldorado. The built-up village of Madoc has been part of the Municipality of Centre Hastings since 1998. The rules differ in the way that matters most: Centre Hastings only permits a second unit on municipal water and sewer, while the Township has neither and permits one on a well and septic. Your property tax bill tells you which you are in.
Can you build a garden suite / ADU in the Township of Madoc?
Yes. By-law 1431-2017 added §5.19.1 to the zoning by-law, permitting a second dwelling unit as-of-right in the Rural, Rural Residential, Waterfront Residential, R1, R2 and Multiple Residential zones — either inside your existing house or in a detached building on the same lot, but not both. One second unit per lot, and it is not permitted on an undersized lot, a lot without public-road frontage, in a regulated floodplain, or on a lot abutting a lake designated at-capacity.
How big can a backyard suite be in the Township of Madoc?
There is no maximum. §5.19.1 sets no floor-area cap — the governing limit is that all accessory buildings on the lot together may cover at most 10% of the lot, which on typical rural acreage is thousands of square feet. The practical limits are your zone’s principal-building setbacks, your septic capacity, and your budget. The open question is at the other end: the Rural Residential zone sets a 74.3 m² (800 sq ft) MINIMUM gross floor area for a dwelling, and whether that is applied to a second unit is worth confirming with Hastings County planning before you order a compact model.
Can you build an ADU on well and septic in the Township of Madoc?
Yes — and you have no other option, because there is no municipal water or sewer anywhere in the Township. §5.19.1 imposes no servicing test of its own, so the gate is whether your septic system has capacity for the extra unit. The Township issues its own septic permits through the Building Inspection Service Board, applied for in the same Cloudpermit application as the building permit under the "Sewage System" category — not through a health unit.
Can you put a modular home in the Township of Madoc, Ontario?
Yes. On land you own, a modular home on a permanent foundation is legal residential housing under the Ontario Building Code throughout the Township — as the principal dwelling or as the second dwelling unit, subject to the zoning standards and permits above.
How much does a modular home or backyard suite cost in the Township of Madoc?
Modular home models start at $175,696 and run to about $338,000 for the largest layouts; backyard ADU models start at $96,244. Site work, foundation, delivery, and permits are additional.
Can I get a mortgage on a modular home in the Township of Madoc?
Yes — on a permanent foundation it is financed as real property, including via CMHC Prefab Plus (5% down on the first $500,000).
