Modular Homes & Garden Suites in Hanover, Ontario
Factory-direct modular homes and backyard suites for the Town of Hanover — the Saugeen River town at Grey County's western edge. Hanover's by-law does something rare: it names the backyard unit itself. The 'Additional Detached Dwelling' — the by-law's own text calls it a garden suite, and it's permanent, not a temporary-use approval — is as-of-right in the R1, R2 and R3 zones at up to 69 m² (≈743 sq ft). The number to check first, though, is 56: all accessory buildings together (garage, shed, suite) are capped at 56 m² (≈603 sq ft) of building area, and an existing garage eats into it. Here's what By-law 2912-15 allows, what it costs, and the rules that apply.
What you can build in Hanover
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 Hanover'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? →
Find your backyard suite — 3 quick questions

1 · Who's it for?
2 · What layout?
3 · What size feels right? (Hanover lots typically allow up to ~600 sq ft)
Hanover caps the unit at 69 m² (≈743 sq ft) — but ALL accessory buildings together are capped at the lesser of 10% of the lot or 56 m² (≈603 sq ft) of building area, so on a lot with an existing garage or shed the shared cap usually binds first. Check what's already in the yard, then 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 — Hanover permits a detached Additional Residential Unit on most serviced residential lots. The specifics, from Town of Hanover Comprehensive Zoning By-law 2912-15, as amended by By-laws 3269-23 and 3308-24 — Additional Detached Dwellings (consolidation to June 17, 2024):
| Max size | Up to 69 m² (≈743 sq ft) and two bedrooms for the detached unit, 5 m (≈16 ft) tall — the by-law's own text calls it a garden suite, and it's PERMANENT, as-of-right in the R1, R2 and R3 zones (By-law 3269-23). The in-house alternative, the 'Additional Attached Dwelling', runs to 83 m² (≈893 sq ft). |
|---|---|
| The shared 56 m² cap | The quiet constraint: all accessory buildings together — garage, shed and suite — are capped at the LESSER of 10% of the lot or 56 m² (≈603 sq ft) of building area (§7.2.3, By-law 3308-24). On a lot with an existing double garage the shared cap can bind long before the 69 m² unit cap. Check what's already in the yard first. |
| Setbacks & address | Town-scaled: 1.0 m (≈3.3 ft) from side and rear lot lines (§7.2.2); where the rear or side line abuts a street, the principal-building setback applies instead. The Town assigns the suite its own municipal address for emergency services. |
| Parking | One space for the unit on top of the home's two — and Hanover's by-law has NO tandem allowance, so all three spaces must genuinely fit side-by-side on the lot (§6.13). Measure the driveway before you design. |
| Servicing | Hanover is a fully municipally serviced town (§6.29) — no septic project, connection is process. That also means Bill 23’s as-of-right override applies here rather than being blocked by private servicing. |
| Conservation | The Saugeen River runs through town: on a riverside lot, Saugeen Valley Conservation Authority (SVCA) floodplain approval (O.Reg 169/06) is a separate desk from the building permit, and the Hazard (H) zone bars habitable buildings outright. |
Getting your building permit in Hanover
An eligible lot still needs a building permit before anything is delivered. Here's how Hanover's process actually works — verified against the Hanover building department's own pages.
How do you apply for an ADU building permit in Hanover?
Through Cloudpermit (Town of Hanover Building Department) (application portal ↗). Hanover runs its own building department (341 10th Street; inquiry@hanover.ca, 519-364-2780 ext. 1222; Building Inspector & Plans Examiner ext. 1227). Applications go through Cloudpermit, or in person / by mail on request — a rarity these days. Inspections are booked at least two full business days ahead. Hanover's building-permit page ↗
- Confirm the zoning envelope first — the Additional Detached Dwelling is as-of-right in the R1, R2 and R3 zones at up to 69 m² (≈743 sq ft), two bedrooms and 5 m tall, but the binding check is usually the shared accessory cap: ALL accessory buildings together are limited to the lesser of 10% of the lot or 56 m² of building area (§7.2.3), and the parking rule allows no tandem — three genuinely separate spaces must fit (§6.13).
- Check the river — on a lot in the Saugeen Valley Conservation Authority's regulated area (the Saugeen runs through town), SVCA approval under O.Reg 169/06 is a separate desk that comes before the building permit.
- Plan the services connection — Hanover requires municipal water and sanitary town-wide (§6.29), so there is no septic project; new water/sewer hook-ups are charged at cost recovery (Rates & Fees By-law 3357-25, Schedule F).
- Retain a qualified BCIN designer for the Ontario Building Code drawings, and prepare the site plan to the Town's own checklist — road allowance and street name, all lot dimensions, every underground service, existing buildings on both sides of the lot lines, and the driveway.
- Apply through Cloudpermit and pay the permit fee — the residential line prices at $8.00 per $1,000 of construction value (minimum $60), though the schedule also carries a $2.25/sq ft 'new residential occupancies' line; ask the Building Department which applies to a detached unit before budgeting.
- Review, issuance, inspections — the Town assigns the suite its own municipal address for emergency services, and starting work before the permit adds a $150 investigation fee on top.
What does a Hanover ADU permit application need?
- Application for a Permit to Construct or Demolish + Schedule 1 Designer Information (BCIN, or the homeowner exemption)
- Site plan per the Town's By-law 2486-05 checklist — road allowance, all lot dimensions, underground services, existing buildings relative to all lot lines, driveway location, north arrow and scale
- Two sets of building plans — floor plans, elevations, cross-sections, plumbing and heating as applicable
- Engineered, stamped specifications where floor or roof truss systems are involved
- SVCA approval (or written confirmation it isn't needed) on a lot in the Saugeen regulated area
How much does an ADU building permit cost in Hanover?
Fees follow Hanover's Rates & Fees By-law 3357-25 (effective January 1, 2026): the residential building permit prices at $8.00 per $1,000 of construction value with a $60 minimum — roughly $1,200 on a $150,000 backyard suite — though the schedule also carries a $2.25 per sq ft 'new residential occupancies' line (about $1,350 on a 600 sq ft unit); which line applies to a detached unit is a question for the Building Department (519-364-2780 ext. 1222). Plumbing adds $100 plus $8 per fixture. All figures are estimates.
| Building permit — residential | $8.00 per $1,000 (or part) of estimated construction value, minimum $60 (By-law 3357-25, Schedule I); the schedule's separate 'new residential occupancies' line of $2.25/sq ft may apply instead — confirm which with the Building Department |
|---|---|
| Plumbing permit | $100 per application plus $8.00 per fixture (By-law 3357-25, Schedule I) |
| Water & sewer hook-up | Charged at cost recovery — no flat fee is published (By-law 3357-25, Schedule F); the unit connects to municipal services, so there is no septic leg |
| SVCA permit — regulated riverside lots only | A separate Saugeen Valley Conservation Authority application and fee (SVCA's own current fee schedule applies) before the building permit |
| Development charges | Hanover has NO municipal development-charge by-law in force (a first-ever DC background study was commissioned in 2024 — confirm nothing has been enacted since). Grey County's charge ($2,617 single-detached, 2022 base, indexed annually) carries pre-Bill-23 exemption wording ('in or attached to' an existing dwelling) — confirm the County's treatment of a detached unit |
Hanover itself currently charges no municipal development charges — there is no Town DC by-law in force, which is genuinely unusual and worth confirming hasn't changed when you apply. Grey County's charge ($2,617 single-detached, 2022 base, indexed) carries exemption wording written before Bill 23 that speaks to units 'in or attached to' the house; the Development Charges Act's statutory ADU exemption governs, but confirm the County's treatment of a detached unit when the permit is issued.
How long does an ADU building permit take in Hanover?
Ontario's Building Code requires a decision on a complete house-class application within 10 business days. Hanover publishes no turnaround figure of its own and requires inspections booked at least two full business days ahead. On a riverside lot the SVCA approval comes before the permit — sequence it first.
Worth knowing before you apply
- Measure the yard before you design: the 69 m² unit cap is rarely the binding number — the lesser-of-10%-or-56 m² cap on ALL accessory buildings together (§7.2.3) means an existing garage can shrink the buildable suite, and the no-tandem parking rule means three real spaces must fit side by side.
- The Town assigns the suite its own municipal address for emergency services — automatic, not an extra application.
- No municipal development charges exist in Hanover today — a genuine cost advantage over the growth municipalities; only the County's (much smaller, likely exempt) charge is in play.
- SVCA floodplain approval is a separate desk from the building permit on Saugeen-side lots, and the Hazard (H) zone bars habitable buildings outright.
- Starting work before the permit adds a $150 investigation fee on top of the permit fee.
Fees and timelines are estimates from Hanover's published schedules, verified August 28, 2026. Rates and processes change — always confirm current requirements with the building department before you apply.
Grants & financing in Hanover
Development charges — exempt for a qualifying ADU — Ontario's Development Charges Act (s.2(3)) exempts qualifying additional residential units — up to two units added to an existing home, or one unit in an ancillary building. Grey County's charge ($2,617 single-detached, 2022 schedule, indexed) carries exemption wording written before Bill 23 that speaks to units 'in or attached to' the house — confirm the County's and the Town's treatment of a detached unit when the permit is issued.

Hanover modular homes — FAQ
Can you build a garden suite / ADU in Hanover?
Yes — Hanover codified it by name: the 'Additional Detached Dwelling' (the by-law itself calls it a garden suite, and it's permanent) is as-of-right in the R1, R2 and R3 zones, up to 69 m² (≈743 sq ft) and two bedrooms, needing only a building permit (By-law 3269-23). R4 and R5 apartment/multi-unit lots don't carry the right — those read 'not as-of-right' rather than no.
How big can a backyard suite be in Hanover?
The unit itself is capped at 69 m² (≈743 sq ft) — but the binding number is usually 56: all accessory buildings together are capped at the lesser of 10% of the lot or 56 m² (≈603 sq ft) of building area (§7.2.3). On an empty yard a single-storey suite tops out around 56 m²; an existing garage or shed lowers it. Enter your address and tell us what’s in the yard for the real number.
Can you build an ADU on well and septic in Hanover?
No — Hanover requires municipal water and sanitary sewer town-wide (§6.29), so the unit connects to town services. On a serviced town lot that’s a connection design, not a constraint — no septic assessment, no capacity letter.
Can you put a modular home in Hanover, Ontario?
Yes. On land you own, a CSA A277 modular home on a permanent foundation is legal residential housing under the Ontario Building Code throughout Hanover — as the principal dwelling, or as the Additional Detached Dwelling in your backyard. The compact backyard-suite models fit the 56–69 m² envelope naturally.
How much does a modular home or backyard suite cost in Hanover?
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 Hanover?
Yes — on a permanent foundation it is financed as real property, including via CMHC Prefab Plus (5% down on the first $500,000).
