## Garden Suite Costs in Toronto, Explained

A garden suite is a separate backyard home, also called an additional residential unit (ARU) or detached accessory dwelling unit. In Toronto in 2026, the all-in turnkey price for one runs $160,000 to $380,000. That range is wide because lots are different. A 40 sqm studio on an open lot with good services sits near the bottom. A 60 sqm suite with a loft on a ravine lot with an old hydro service sits near the top.

### What does a garden suite cost in Toronto by size?

For a detached site-built suite, expect $160,000 to $240,000 at 40 sqm and $220,000 to $380,000 at 60 sqm. Per square metre that works out to roughly $4,000 to $6,300 all-in, higher on small suites because kitchens, bathrooms and mechanical systems cost the same whatever the size. Toronto Building permit fees, design and engineering are part of the total. Prefab-hybrid suites save $20,000 to $40,000, and garage conversions can start at $120,000 when the existing structure is sound.

### Which rules affect the cost under By-law 574-2022?

By-law 574-2022 and Zoning By-law 569-2013 set the size cap (60 sqm, or 40 sqm on narrower lots), separation from the main house, setbacks and fire access. Those rules shape the footprint and so the price. Overlays add cost: TRCA regulated areas can require a geotechnical review, the Tree Protection By-law can require helical piles near root zones, and a Heritage Conservation District can call for specific cladding. A minor variance at the Committee of Adjustment adds fees and about two months.

### Who gives fixed-price garden suite quotes in Toronto?

Many builders quote a range and adjust it during construction through allowances and change orders. We issue a written fixed price after the feasibility report, because by then we know the lot, the envelope and the utility situation. Our founder, Dmitri Varga, P.Eng and BCIN Part 9, reviews every quote before it goes out.

## How We Build Your Cost Estimate

![Garden suite estimator reviewing a printed site plan and cost spreadsheet with a Toronto lot survey on the desk](/images/content/garden-suite-estimator-reviewing-a-site-plan-and-c.webp)

### 1\. Free consult

A short call or site walk. We ask about goals (rental, family, office or retirement), lot width, lane access, garage and timeline, and give you a realistic range.

### 2\. Written feasibility report

Our 

garden suite site evaluation

[/garden-suite-feasibility/ →](/garden-suite-feasibility/)

 confirms eligibility, measures the envelope and checks soil, access and utility capacity. It costs $1,200 to $2,800 with zero deposit, and it is what makes a fixed price possible.

### 3\. Fixed-price quote

Within 2 weeks of the report, you get a written CAD quote showing hard and soft costs, material allowances, exclusions and the 5-stage draw schedule.

### 4\. Contract with written change control

10% at contract, then draws at permit, foundation, framing, finishes and occupancy. Any change needs your written approval and a written price before work starts.

## Garden Suite Cost Breakdown (60 sqm Example)

## What Drives the Price on a Toronto Lot?

**Utility upgrades.** Older homes in Riverdale, Leslieville and East York often have a 60-amp electrical service or a 1/2 inch galvanized water line. A Toronto Hydro service upgrade or new Toronto Water line can add $12,000 to $30,000.

**Foundation choice.** A frost-protected shallow foundation on an open lot is the least costly. Helical piles cost more but protect tree roots and work on poor soil or tight access.

**Access.** Narrow side yards mean hand-carrying materials or booking a crane and a street occupancy permit.

**Size and storeys.** A loft or second storey adds structure and stairs, but leaves more yard.

**Finish level.** Our standard spec meets Toronto Green Standard Tier 1. Upgraded or premium finishes add roughly 12 to 25 percent to construction.

> **The cheapest garden suite is the one you only design once**
> 
> Redrawing a suite after a Zoning Examiner rejection costs $3,000 to $8,000 in fees and 8 to 12 weeks of carrying costs. Measuring the envelope first is the single best cost control.

## Cost by Build Type

| Build type | Typical Toronto range | Page |
| --- | --- | --- |
| Detached site-built | $180K - $340K | Detached garden suites |
| Prefab-hybrid | $140K - $240K | Prefab garden suites |
| Attached | $160K - $280K | Attached garden suites |
| Garage conversion | $120K - $220K | Garage conversions |
| Laneway house | $200K - $380K | Laneway houses |

## Does a Garden Suite Pay for Itself?

Toronto garden suites typically rent for $2,200 to $3,400 a month. A $280,000 suite renting at $2,800, after a vacancy allowance and about $4,500 a year in taxes, insurance and upkeep, nets roughly $27,750 a year, which is a payback of about 10 years before financing. Our

Client Proof

## What Clients Say About Our Cost Estimation Work

Feedback from homeowners we have designed, permitted and built for across Toronto. Project prices are the fixed contract amounts.

Leila K. • Yonge-Eglinton

$298,000 detached home office suite

> “Our design needed a small height variance. I was dreading the Committee of Adjustment, but the expeditor prepared the application, briefed our neighbours and handled the hearing. It added about two months, exactly as the feasibility report warned. Meanwhile the team finished design and lined up Toronto Hydro so nothing else slipped. The office is quiet, warm in February and permitted down to the last outlet. No change orders, no excuses.”

Marcus T. • Davisville

$198,000 attached in-law suite

> “Fixed price meant fixed price. My mother has her own entry and her own thermostat, and we never argued about an extra.”

Darshan M. • Leaside

$288,000 detached garden suite

> “They gave us the written feasibility report inside two weeks. The variance we needed for the TRCA ravine lot was flagged before we spent a dollar on drawings. Permit cleared in 11 weeks. Suite ready for tenants in month 7.”

Common Questions

## Cost Estimation FAQs: Toronto Homeowner Questions

Straight answers on cost, timelines, by-laws and permits for Toronto lots.

### How much does a garden suite cost in Toronto in 2026?

Full-build turnkey garden suites in Toronto run $220,000 to $380,000 for a 60 sqm detached unit, including design, permits, construction and delivery. Smaller 40 sqm suites run $160,000 to $240,000. Prefab-hybrid suites save $20,000 to $40,000 compared with site-built. Garage conversions start near $120,000 because the structure already exists, and laneway houses run $200,000 to $380,000. The price on your lot depends on five things: size, build type, foundation, utility upgrades and finish level. Lot conditions such as a TRCA ravine slope, protected trees or a narrow side yard can add $15,000 to $35,000. Your written feasibility report sets a budget range before any contract.

### What is included in a turnkey garden suite price?

Our turnkey price includes the feasibility report findings, design and engineering, Toronto Building Division permits, utility connections, foundation, structure, envelope, mechanical systems, interior finishes, final inspections and occupancy. City permit fees and any variance fees are billed at cost and shown in the quote.

### What are hard costs and soft costs?

Soft costs are design, engineering, surveys, arborist reports, permits and project management, usually $14,000 to $30,000 on a garden suite. Hard costs are everything built on site: foundation, framing, roofing, windows, mechanical, electrical, plumbing and finishes. Hard costs are the larger share, often 85 to 90 percent.

### Do I pay development charges on a garden suite?

No. Under provincial Bill 23, development charges are waived for additional residential units such as garden suites and laneway suites. You still pay City building permit fees, which scale with floor area.

### How do payments work?

Zero deposit on the feasibility report, 10% at contract, then 5 staged draws at permit, foundation, framing, finishes and occupancy. No change orders without your written approval.

### Why do some garden suite quotes grow during construction?

Usually because of low material allowances, unpriced utility upgrades or foundation surprises. We price utilities and foundations from the feasibility findings, set realistic allowances and put the change order policy in writing.

### Is prefab cheaper than site-built?

Prefab-hybrid suites typically save $20,000 to $40,000 and shorten the on-site schedule to about 10 weeks. Foundations, servicing and permits cost the same, so savings come from factory framing and less site labour.

### Will a garden suite raise my property taxes?

MPAC may reassess the property after the suite is built, which can raise your property tax. The amount varies. We include an estimate of carrying costs in the rental calculator.

### Is there a rebate for rental garden suites?

Long-term rental suites may qualify for the HST New Residential Rental Property Rebate. Rules change, so confirm with your accountant. We supply the documents the application needs.

### How fast can I get a quote?

The consult is the same week. The feasibility report takes about 2 weeks, and the fixed-price quote follows within 2 weeks of the report.

### Still have a question about your lot?

Send us the address and lot width. We will tell you what applies before you pay for anything.
