Multiplex Appraisal in Toronto: How Triplex, Fourplex, and Small Apartment Buildings Are Actually Valued
You have done the numbers on a fourplex in East York. The rents look strong, the location is good, and the recent zoning reforms mean you could potentially add a garden suite later. Your lender sends an appraiser. The report comes back $80,000 below what you expected.
This happens more often than investors realize. And in most cases, it is not a bad appraiser or a slow market. It is a misunderstanding of how multiplex properties are actually valued, specifically the difference between what a property earns and what a lender’s appraiser is instructed to establish.
Understanding how a triplex, fourplex, or small apartment building is appraised in Toronto is not just academic knowledge. It affects how much equity you can pull out on a refinance, whether your BRRRR numbers work, and how you structure an offer on an acquisition. This guide walks through the methodology clearly, covers where the new zoning rules under Bill 23 and Toronto’s multiplex bylaw fit in, and explains how rent control status quietly affects the numbers your appraiser will use.
Why a Multiplex Is Not Valued Like a House
If you own a single family home in Leslieville and a neighbor sells their comparable house for $1.4 million, your home benefits from that sale. The comparable is clean, the adjustments are straightforward, and the value conclusion is anchored to what buyers are paying for similar houses.
Under five units, your duplex, triplex, or fourplex gets treated differently by the lender’s appraisal process. The bank is not primarily looking at how much rent you collect. That statement surprises investors who have spent months building a cash flow model. But it reflects the reality of how lenders approach small multiplexes versus purpose built apartment buildings. Greater Toronto Home Pros
The cutoff is typically at five units. Below five units, most lenders apply residential mortgage rules and their appraiser approaches the file with a primary focus on direct comparison, what similar properties have actually sold for, supported by income analysis as a secondary check. At five units and above, the income approach becomes the primary method and the file often moves into CMHC multi-unit territory.
This distinction matters enormously for how you think about value creation on a small GTA multiplex. A well-renovated two-unit can appraise higher than a three-unit with average finishes on the same street. The appraiser is comparing your property to what buyers have been willing to pay nearby, and a polished property commands stronger comparables than one that just has more doors.

That said, income still factors into the analysis even below five units, particularly on refinancing, and the relationship between rent and appraised value becomes increasingly direct as the unit count approaches five. Understanding all three approaches gives you the full picture.
The Three Valuation Approaches on a Multiplex File
Every CUSPAP compliant appraisal considers three approaches to value: the income approach, the direct comparison approach, and the cost approach. For a multiplex, here is how each actually works in practice.
The Income Approach: Where Rents Become Dollars
The income approach converts the income a property produces into a value estimate. The formula is simple: divide the net operating income (NOI) by the market cap rate. The cap rate reflects what investors are paying per dollar of income for comparable assets in the same submarket.
If a fully occupied Toronto fourplex produces $90,000 in gross annual rent, you subtract vacancy allowance (typically 3 to 5 percent) and operating expenses (property taxes, insurance, maintenance, management, utilities if landlord-paid). The result is NOI. Divide that by the market cap rate and you have the income approach value.
For small multiplex properties in Toronto, cap rates in the 5 to 5.5 percent range currently offer the strongest balance between income and stability in 2026. Using a 5.25 percent cap rate on a NOI of $65,000 produces a value of roughly $1.24 million. Change the cap rate to 5.75 percent and the same NOI produces $1.13 million. That $110,000 difference comes entirely from cap rate selection, which is why your appraiser’s derivation of the cap rate matters. WealthTrack
The NOI itself is where most investors either gain or lose money in the appraisal. The appraiser uses market supported rents for vacant units, not your optimistic projections. Appraisers tend to be conservative with market rent estimates. If you know the area well and believe rents could be higher, that is great for your future cash flow, but do not count on the appraiser seeing it that way for qualification purposes.

The Direct Comparison Approach: Per Unit and Per Suite Analysis
The direct comparison approach analyzes recent sales of similar multiplexes in the area and adjusts for differences. On a multiplex file, the most common metrics are price per unit (the total sale price divided by the number of units) and price per square foot of gross living area.
A triplex in Riverdale at $1.2 million with three units works out to $400,000 per unit. An adjusted comparable fourplex in the same area at $1.5 million works out to $375,000 per unit. These figures anchor the comparison analysis alongside direct dollar adjustments for condition, size, building type, and location.
The building type sets the starting point, not the number of units. A detached house will almost always appraise higher than a semi-detached on the same street, even if both collect the same rent. This is why two investors can do essentially the same conversion and see meaningfully different appraisal results depending on whether their starting building was a detached house, a semi, or a row house. Greater Toronto Home Pros
The comparable scarcity issue is real in some Toronto submarkets. Recent sales of triplexes in certain established neighbourhoods are limited, which means the appraiser may need to expand the geographic search or go back further in time, with appropriate adjustments. A well-scoped appraisal documents this search methodology clearly.
The Cost Approach: Land Plus Build Minus Depreciation
The cost approach estimates what it would cost to rebuild the structure today, deducts depreciation (physical wear, functional obsolescence, external obsolescence), and adds land value. On newer multiplexes built in the past few years, this approach carries meaningful weight because the build cost is recent and verifiable. On a 1960s triplex with aging mechanical systems, the depreciation analysis is more complex and the approach typically carries less persuasive weight in the reconciliation.
Multifamily construction costs are more than 30 percent above levels five years ago, per Urban Land Institute data from 2026. This matters for the cost approach on newly built multiplexes, where the replacement cost is high and the development spread (the difference between what existing buildings trade for versus what it costs to build new) affects investor behavior across the market.

How Bill 23 and Toronto’s Fourplex Bylaw Changed the Value Equation
The zoning reform story for Toronto multiplex investors has moved fast and the details matter for valuation purposes.
Bill 23, the More Homes Built Faster Act, received Royal Assent November 28, 2022, and required all Ontario municipalities to permit up to three residential units per lot as of right on any residential lot with municipal services. Toronto City Council went further, extending to four units as of right on all Neighbourhood-designated lots covering the RD, RS, and RT residential zones, which represent approximately 70 percent of Toronto’s residential land. VanPlex
On May 10, 2023, City Council adopted city-wide permissions for up to four units as of right (OPA Law 0473, Zoning Law 0474). The zoning took effect May 12, 2023 and the Official Plan amendment on June 14, 2023. VanPlex
Then in 2025, the math changed again. Bill 185, effective January 2025, waived development charges entirely for up to four units. Pre-reform development charges on a Toronto fourplex reached $200,000 to $270,000, effectively making most projects unfeasible. The elimination of development charges changed the math fundamentally. VanPlex
As of June 2025, sixplexes (five and six units) are now permitted as of right in the Toronto and East York district and Ward 23 in Scarborough North, with a city-wide study underway. The DC waiver currently applies to fourplexes. For sixplexes, development charges apply on units five and six. Landsignal ai blog
How does all of this feed into an appraisal?
Highest and best use analysis. Before any value conclusion, the appraiser must determine the highest and best use of the property, meaning the legally permissible, physically possible, financially feasible use that produces the highest value. On a residential lot in Toronto that can now accommodate four units as of right without rezoning, the highest and best use analysis has shifted. A property previously valued as a single family home or duplex may now support a higher use that the appraiser must consider.
Land value uplift. Lots with development potential for three or four units are worth more on a per square foot basis than identical lots limited to one unit. As the zoning reforms became established and the market digested them, land values in Toronto neighborhoods adjusted to reflect the new as of right capacity. An appraiser working a conversion or new build file needs current comparable land sales that reflect post-reform market conditions.
The “as if complete, as stabilized” scenario. On a construction or conversion file, the lender often needs three values: the as is current value, the as if complete value (what it will be worth when construction is finished), and the as stabilized value (what it will be worth once fully leased at market rents). Each is a distinct analysis with its own assumptions, and the income approach drives the as stabilized conclusion.
One important note on development charges that often causes confusion. Bill 23 exempts the second and third units from development charges. Toronto’s by-law extended to four units, but the provincial exemption is not written to automatically cover the fourth unit. Before finalizing a fourplex pro forma, the DC treatment of the fourth unit should be confirmed with the City directly. An appraiser assessing development feasibility for a highest and best use analysis needs accurate cost inputs, and DC assumptions that do not match the City’s current bylaw undermine the analysis. VanPlex
How Rent Control Status Affects Your Appraised Value
This is one of the most practically important and least understood aspects of Toronto multiplex valuation. Whether the units in your building are subject to rent control directly affects what the income approach will produce.
Ontario’s rent control applies to residential units first occupied on or before November 15, 2018. Rental units first occupied after November 15, 2018 are generally exempt from rent control, meaning landlords are not subject to the annual rent increase guideline and can set market-driven rents between tenancies. The annual guideline was 2.5 percent in 2024. Allowayproperty
The appraisal implication is direct. Consider two Toronto triplexes, similar in size and location, both currently fully leased. Building A was built in 2015 and is subject to rent control. Its long-term tenants are paying rents that have tracked the annual guideline for several years and now sit meaningfully below current market. Building B is a newly converted triplex completed in 2019 and is fully rent control exempt. Its units lease at current market rates.
The income approach on Building A produces a NOI based on the below-market in-place rents, not on what the units could achieve if vacant today. The appraiser uses in-place rents for stabilized existing tenancies. Toronto tenants in rent control exempted units are paying anywhere from $800 to over $1,000 extra every single month compared to units protected by rent control. That monthly gap, multiplied by the number of units and annualized, translates to a substantial difference in NOI and therefore in appraised value. TorontoLivings
Building B’s NOI reflects market rents. At a 5.25 percent cap rate, an additional $10,000 in annual NOI from higher rents produces approximately $190,000 in additional appraised value. Across a four-unit building where all units are at market versus below market, the value difference can easily reach $300,000 to $500,000 on the same physical asset.
This is why investors acquiring multiplexes in Toronto pay close attention to tenancy status and unit occupancy dates. A building with existing long-term tenants in rent-controlled units, even at below market rents, may appraise differently than the same building with vacant units that will be leased at current market rates. The appraiser uses in-place rents on occupied units and market rents for vacant or newly leased units.
What Per-Unit Analysis Actually Tells You
Beyond the income approach, per unit metrics give investors a useful benchmark for whether a property is priced reasonably against comparable assets in the submarket.
Current Toronto market conditions (based on 2026 transaction data) produce per unit values across different triplex and fourplex configurations that vary significantly by neighbourhood, building type, and unit mix. A three bedroom unit in a well-positioned triplex in Leslieville or Riverdale commands a meaningfully higher per-unit value than a one bedroom unit in a fourplex in Scarborough, even when the gross rents are similar on a per-square-foot basis.
Why does this matter to you as an investor? Because per-unit benchmarking is how you reality-check both the asking price and the appraisal conclusion. If comparable fourplexes in your target neighbourhood have been trading at $350,000 to $400,000 per unit and the property you are acquiring is priced at $500,000 per unit based on a renovation story, your appraisal will not deliver the income approach value you need unless the rents and cap rate fully support it.
Unit mix also drives value. A fourplex with four two-bedroom units in a family-oriented neighbourhood like Danforth Village or Birch Cliff will typically command a higher per-unit value than a fourplex with four bachelor units in the same location. The appraiser selects comparables with similar unit configurations and applies adjustments for differences. If your unit mix is unusual for the area, the comparable selection becomes more challenging and the adjustments more important.
Legal Units vs. Unpermitted Units: The Appraisal Risk
This is where many investors get caught. A property listed as a triplex may have units that were converted without permits or that do not comply with the Ontario Building Code requirements for legal dwelling units. This affects the appraisal in two ways.
First, the appraiser can only count legally permitted units. An unpermitted basement suite will not count toward financing and could actually hurt the application if discovered during the appraisal. A “triplex” with two legal units and one unpermitted basement suite is a duplex for appraisal purposes, which changes both the comparison analysis and the income analysis. Quadrantarchitects
Second, unpermitted units affect the highest and best use analysis. If the property is currently operating as a triplex but only has two legal units, the appraiser must consider whether the third unit could be legalized, at what cost, and what the value of the legal triplex would be, then weigh that against the current illegal configuration. The value conclusion is based on the legal permitted use, not on what is currently in place.
Since Toronto’s fourplex bylaw came into effect in May 2023, many previously non-conforming conversions may now be legalizeable under the new as-of-right framework, but the permit and building code compliance process is still required. An investor acquiring a property with unpermitted units and relying on a triplex or fourplex appraisal value needs to understand this exposure before closing.
Garden Suites, Laneway Houses, and What They Add
The ability to add a laneway suite or garden suite to an existing multiplex lot is a legitimate value consideration in Toronto, but how the appraiser treats it is nuanced.
A lot that abuts a public laneway and qualifies for a laneway suite (permitted city-wide since 2019) has additional development potential beyond the four units allowed in the main building. A garden suite in the rear yard (permitted city-wide since 2022) represents similar potential.
The appraiser’s treatment depends on whether the suite already exists or whether it is merely potential. If the garden suite is already built and leased, its income is in the NOI and its cost is in the cost approach. If it is future potential, the appraiser must assess whether to reflect that potential as a positive value factor in the highest and best use analysis, and if so, how to quantify it against comparable properties with and without the additional suite.
The key point: future development potential is a value factor, but it is not valued as though the suite already exists unless the comparable evidence directly supports a premium for that potential. An appraiser who adds the full estimated value of a future garden suite to a current as-is value without comparable support is speculating, not valuing.
What Drives Your Multiplex Appraisal Up or Down
To summarize the practical variables that move the appraisal on a Toronto triplex, fourplex, or small apartment building:
Pushing value up:
Rents at or above market with current leases in place (especially on post-2018 exempt units). Legal, permitted units throughout. Strong, recent comparable sales within a tight geographic radius. Well-maintained building with low deferred maintenance. Detached building type over semi or row. Development potential for garden or laneway suite where already proven in comparables. Post-2018 first occupancy on all units (rent control exempt).
Pushing value down:
Below-market in-place rents in rent-controlled units with long-term tenants. Unpermitted units or units built before current OBC standards. High deferred maintenance or aging mechanical systems. Comparable scarcity in the submarket requiring distant or time-adjusted comparables. Building type that limits comparable pool.
Neutral but often misunderstood:
The number of units alone does not drive value above the direct comparison evidence. An investor who adds a third unit to a duplex and expects the appraiser to credit the full income value of that unit without supporting comparable sales will often be disappointed. The income approach and the comparison approach need to triangulate on a consistent conclusion.

Frequently Asked Questions
- What is the primary valuation approach for a Toronto triplex or fourplex?
For properties below five units, most lenders require a primarily residential appraisal where the direct comparison approach is the primary method, supported by income analysis. The comparable sales the appraiser can identify for similar multiplexes in your specific area carry significant weight. At five units and above, the income approach becomes primary. This distinction has real consequences for BRRRR investors who assume strong rents automatically translate into a high appraised value on a triplex or fourplex. - Does rent control status affect my multiplex appraisal?
Yes, meaningfully. Ontario’s rent control applies to units first occupied on or before November 15, 2018. Units exempt from rent control can be leased at full market rates on turnover. A building with below-market in-place rents in rent-controlled units produces a lower NOI and a lower income approach value than an identical building with market rate exempt units. The gap between a fully controlled building and a fully exempt building in the same location can reach hundreds of thousands of dollars on the appraised value. - How does the Bill 23 fourplex zoning affect my property’s appraised value?
The ability to build up to four units as of right across most Toronto residential lots (under the May 2023 multiplex bylaw) affects highest and best use analysis and land value. Properties that can now legally accommodate four units without rezoning are worth more as land than identical lots that previously required Committee of Adjustment approval. The appraiser must consider this in the highest and best use analysis, particularly on single family homes or under-developed lots where conversion to a fourplex is economically viable. - How are unpermitted units treated in an appraisal?
The appraiser values what is legally permitted. An unpermitted unit does not count toward the income analysis or the unit comparison. A triplex with one unpermitted unit is a duplex for appraisal purposes. This affects both the income approach and the per-unit comparison analysis. Since Toronto’s fourplex bylaw came into effect in May 2023, some previously non-conforming units may now be legalizable under the new framework, but permit compliance is still required before the appraiser can count the unit. - How much does a GTA multiplex appraisal cost?
Residential multiplex appraisals for two to four unit properties generally run from $700 to $1,500 in the GTA. Larger files with five or more units, complex income analysis, or multiple value scenarios (as is, as if complete, as stabilized) for construction financing run higher, typically $2,500 to $5,000. IPS provides a written fee quote before any work begins. - Can I use an appraisal to support a refinance and pull equity out of a Toronto multiplex?
Yes. Refinancing on a multiplex requires the lender to appraise the property, and the appraised value determines your maximum loan at the lender’s LTV threshold. Engaging an independent pre-lender appraisal before submitting the refinancing application lets you understand what the income and comparison analysis will likely produce, which helps you size the refinance appropriately rather than discovering the number on the lender’s timeline.
