What Bill 23 actually means for your Ottawa property

Ottawa just legalized the biggest residential development opportunity in a generation.

In December 2025, Ottawa City Council approved the new Ottawa Comprehensive Zoning By-law, the city's largest zoning reform since 2001. Together with provincial Bill 23 Ottawa (the More Homes Built Faster Act Ottawa), it lets property owners build up to four residential units as-of-right on virtually any serviced residential lot, without zoning amendments, Committee of Adjustment hearings, or variances.

With the federal permission for two ADUs per principal dwelling, Ottawa lots can hold up to six units. Three-storey buildings are permitted citywide and mandatory parking minimums are gone. That is as-of-right zoning Ottawa today.

For Ottawa investors, a property zoned for a single-family home in 2024 may now legally accommodate an Ottawa fourplex earning monthly rent from four units. A bungalow on a deep lot can become a duplex with a coach home, and a small commercial property may permit a six-unit residential conversion.

Ottawa fourplex zoning and Ottawa triplex zoning have gone from restricted to permitted. Ottawa multi-unit conversion is now the fastest-growing residential category, and investors are already moving on Ottawa intensification opportunities.

For Ottawa homeowners, Bill 23 Ottawa opens up options. You could add a coach house for adult children, convert your basement to a legal Ottawa secondary dwelling unit, build a duplex addition for aging parents that also brings in rent, or expand upward into a multi-generational triplex.

Ottawa has rewritten the rules for Ottawa missing middle residential property, and Dream Touch takes property owners from feasibility through construction. Ottawa coach home zoning rules are also clearer than they were.

How we guide you through Bill 23

Three Bill 23 service tiers, from "is this even possible?" to "keys in your tenant's hand."

Clients come to Bill 23 at different stages: some are evaluating a purchase, some want more from a property they already own, and some have a property and a plan but need a builder.

What Bill 23 actually says

Bill 23 Ottawa and the Comprehensive Zoning By-law, what's actually permitted in 2026.

Most Ottawa property owners have heard of "Bill 23" but don't know what it permits on their property. This is where the legislation stands now.

01 · Bill 23 (Provincial)

The More Homes Built Faster Act Ottawa, passed by the Ontario Legislature in 2022, sets a baseline municipalities cannot restrict below. Key provisions: up to three residential units permitted as-of-right on most urban serviced residential lots, plus permission for two Additional Dwelling Units (ADUs) per principal dwelling, meaning potentially up to six units per lot. It also reduced municipal development charges and streamlined approvals for small-scale residential intensification.

02 · Ottawa Comprehensive Zoning By-law (Municipal)

Approved by Ottawa City Council on December 17, 2025. Replaces the 2001-era Zoning By-law 2008-250 and the previous R1–R5 zone system with new Ottawa N1 N2 N3 zones and N4–N6 Neighbourhood Zones. Key provisions: Ottawa fourplex zoning permitted as-of-right on all serviced residential lots citywide, three-storey buildings (up to 11 metres) in all urban neighbourhoods, removal of mandatory parking minimums, EV-ready infrastructure requirements, updated tree protection.

03 · The N1–N6 Neighbourhood Zones Ottawa System

The new framework replaces 140+ legacy R-zones with six unified Neighbourhood Zones Ottawa based on density and form rather than dwelling typology. N1 (Neighbourhood Core): low-density with secondary suite and ADU permission. N2 (Neighbourhood Edge): small Ottawa multiplex permission. N3 (Neighbourhood Centre): moderate density. N4–N6: increasing density and height. All N-zones permit four dwellings as-of-right on serviced lots.

04 · Federal Housing Accelerator Fund Coordination

Ottawa's participation in the federal Housing Accelerator Fund requires alignment with federal density mandates. This locks in the Bill 23 Ontario fourplex-as-of-right permission and additional intensification commitments. Federal funding to Ottawa over four years accelerates permit processing and infrastructure capacity for multi-unit construction across Ottawa intensification zones.

What can YOUR Ottawa property accommodate?

Quick reference: Maximum units by Ottawa property type.

Under Bill 23 Ottawa and the Ottawa Comprehensive Zoning By-law, unit potential depends on your property's specifics. The table covers the most common Ottawa residential property types, with Ottawa fourplex, Ottawa triplex zoning, Ottawa duplex conversion, and Ottawa six units zoning scenarios.

Property Type Max Units (Bill 23) Max Units with ADUs Coach Home?
Single-family detached on serviced urban lot4 dwelling unitsUp to 6 (4 + 2 ADUs)Yes (counts as 1 ADU)
Semi-detached home on serviced lot4 per sideUp to 6 per sideYes (lot-size dependent)
Townhouse / row house4 typicalUp to 6 typicalLimited (rear-yard dependent)
Existing duplex4 totalUp to 6 with internal ADUsYes (typically)
Lot in heritage conservation district4 (design-review subject)Up to 6 (heritage approval)Possible (heritage subject)

Your maximum unit potential depends on lot dimensions, setbacks, height, lot coverage, mature tree protection, conservation authority restrictions, and heritage status, and our feasibility assessment checks each of these for your property. Call 613-862-4555 for a 5-minute "quick read" or book a full assessment.

What Ottawa Bill 23 looks like as an investment

The Ottawa Bill 23 investment math, honestly explained.

Below are three Bill 23 Ottawa investment scenarios and what drives each one. Costs and returns depend on property location, lot size, scope, financing structure, and rental market conditions, and your written feasibility report covers all of them.

Scenario 01 / Conservative

Existing Home + Coach Home Addition

Property assumption
Existing single-family home in established Ottawa neighbourhood (Westboro, The Glebe, Manor Park, Centretown)
Cost drivers
Coach home size, foundation and servicing, finish level, and site access
New rental income
A self-contained coach home unit adding monthly rent
Cap rate (additional investment)
9 – 12%
Coach houses →
Scenario 02 / Moderate

Ottawa Duplex Conversion (Existing → Two Units)

Property assumption
Family home with separable layout, often older Ottawa bungalow or 1960s split-level
Cost drivers
Extent of layout changes, separate entrances, fire separation, plumbing and electrical, and finish level
Total rental income
Two legal units generating combined monthly rent
Cap rate (vs. construction cost)
12 – 18%
Multi-unit →
Scenario 03 / Aggressive

Ottawa Fourplex Build or Conversion

Property assumption
Older Ottawa property suitable for full multi-unit conversion or teardown rebuild
Cost drivers
Conversion vs. new build, structural scope, servicing upgrades, parking, and finish level across four units
Total rental income
Four legal units generating combined monthly rent
Cap rate (vs. construction cost)
9 – 15%
Multi-unit →

These ranges reflect current Ottawa rental market conditions and Bill 23-compliant builds. Your own numbers depend on purchase cost, location, financing structure, design choices, and rental positioning. Our feasibility assessment gives property-specific projections, including how-to-build-fourplex-Ottawa timelines and Ottawa rental property zoning verification.

Honest assessment

Bill 23 opportunities and risks Ottawa investors should understand.

Bill 23 Ottawa and as-of-right zoning Ottawa rules have opened real opportunities, and they carry risks. Below are both sides for investors evaluating as-of-right zoning Ottawa, including structural engineering coordination and portfolio precedent.

+ Opportunities

Bill 23 opportunities

  • As-of-right zoningMost multi-unit conversions no longer require Committee of Adjustment hearings, eliminating 3–6 months from timelines.
  • Reduced development chargesBill 23 substantially reduces municipal DCs for multi-unit residential, sometimes by tens of thousands per project.
  • Federal Housing Accelerator FundOttawa's participation accelerates permit processing for multi-unit projects.
  • Strong rental marketOttawa rental vacancy at historic lows; demand for multi-unit rentals exceeds supply.
  • Income property tax advantagesMulti-unit properties qualify for capital cost allowance, expense deductibility, and other investment structures.
  • Property value appreciationMulti-unit properties in Ottawa appreciating faster than single-family homes.
  • Future-proof investmentAligned with provincial and federal housing policy direction; unlikely to face regulatory rollback.
! Risks

Risks to understand

  • Construction cost inflationMulti-unit construction costs in Ottawa have risen 15–25% since 2022; projects today cost more than projections from even 12 months ago.
  • Financing complexityMulti-unit construction financing is more complex than single-family; requires specific lender expertise and often higher down payments.
  • Heritage and conservation restrictionsHeritage districts, conservation authority lands, and floodplains can limit Bill 23 opportunities significantly.
  • Tree protection and landscapingOttawa's strengthened tree protection by-law affects setbacks and landscaping requirements.
  • Tenant management responsibilitiesBecoming a multi-unit landlord involves Ontario Residential Tenancies Act compliance, property management, and tenant relations.
  • Municipal infrastructure capacitySome Ottawa neighbourhoods have water/sewer capacity constraints that may limit unit count regardless of zoning.
  • Comprehensive Zoning By-law appealsWhile approved December 2025, appeals through Ontario Land Tribunal may delay full enactment in some areas through September 2026.

Our feasibility assessment weighs these risks for your property and investment scenario, so you decide with realistic expectations. We assess properties across Ottawa intensification zones, including Centretown, The Glebe, Barrhaven, Kanata, and Orleans.

Common questions

Ottawa Bill 23 questions, answered.

These are the questions Ottawa investors and homeowners ask most often about Bill 23 Ottawa and the new Ottawa Comprehensive Zoning By-law, such as "can I build a fourplex in Ottawa" and "how many units can I build on my Ottawa property."

Call 613-862-4555
On most serviced urban residential lots, yes. That's the as-of-right zoning Ottawa permission set by Ottawa's Comprehensive Zoning By-law (approved December 17, 2025) and Bill 23. Lot dimensions, setbacks, height, lot coverage, mature tree protection, heritage status, and infrastructure capacity still shape what fits. Our feasibility assessment works out what your property can hold.
Bill 23 permits up to three principal dwelling units. Ottawa's Comprehensive Zoning By-law extends this to four dwelling units on serviced lots, and Ottawa six units zoning becomes realistic when you add the federally-mandated two ADUs per principal dwelling. The practical maximum depends on lot dimensions, configuration, and zoning constraints. Many Ottawa properties can hold 4–6 units.
Yes. Bill 23 removes the need for zoning amendments and most Committee of Adjustment hearings, but you still need building permits. You submit through MyServiceOttawa, City of Ottawa Building Code Services reviews the application, and it needs BCIN-certified architectural drawings and Schedule 1 designer documentation. Our permit concierge service handles this for you.
Ottawa City Council approved it on December 17, 2025, and enactment is expected in mid-March 2026, followed by a 20-day appeal period. OLT hearings may delay full enactment in appealed areas, with an OLT decision expected by September 2026. Provisions that aren't appealed take effect on enactment. We track which provisions are in force for your area.
The main drivers are whether you convert an existing home or build new, structural scope, servicing and utility upgrades, parking, unit count and size, and finish level. A conversion typically costs less than a ground-up build, and a coach home addition less again. Your feasibility assessment includes a written budget range for your property, so you plan with real numbers.
An Ottawa fourplex earns combined monthly rent from its four units. The amount depends on neighbourhood, unit size, finish quality, and rental positioning. Centretown, Sandy Hill, the Civic Hospital area, and Alta Vista are strong markets. Your feasibility assessment includes realistic rental projections for your property.
No. Heritage conservation district properties go through design review by Ottawa's Built Heritage Committee, and designs must be compatible with the heritage character, but the Bill 23 unit permission still applies. Many Ottawa heritage homes in The Glebe, Centretown, Sandy Hill, New Edinburgh, and Old Ottawa South have been successfully converted to multi-unit configurations.
Yes. The Ottawa Zoning By-law 2025 eliminates mandatory minimum parking requirements citywide. Property owners decide parking based on market demand, site constraints, and project economics. Maximum parking rules apply near rapid transit stations, and 25% of parking spaces in mid- and high-rise developments must be EV-ready.
Often yes, depending on lot size and configuration. The four principal dwelling units under Bill 23 / Ottawa's Comprehensive Zoning By-law plus a coach home (which counts as one of the two permitted ADUs) can result in five total units. Ottawa ADU rules allow this on larger lots; lot dimensions and setbacks determine feasibility.
No. Bill 23 ADU permissions don't depend on owner-occupancy, so investors can build purely for rental income. Some federal financing programs (CMHC MLI) have their own occupancy or rental rate requirements, but those come from the program, not from zoning.
Realistic Ottawa Bill 23 timelines: feasibility assessment 2–3 weeks; design and drawings 4–10 weeks; structural engineering 2–6 weeks (parallel); permit review 8–24 weeks; construction 6–14 months. Total feasibility-to-occupancy: typically 8–18 months for moderate projects, 12–24 months for complex projects.
Yes, in many cases. Bill 23 substantially reduced municipal development charges for residential intensification. As of October 2025, Council approved DCs are due at first occupancy permit (not at permit issuance) for residential occupancies, on an interest-free basis for 18 months, which helps project cash flow.
Yes. Multi-unit financing has expanded under Bill 23 and federal housing initiatives. Options: traditional commercial multi-unit mortgages, CMHC MLI Select (purpose-built rentals with affordability/sustainability commitments), conventional residential mortgages for 1–4 unit properties, and construction-to-permanent financing. We introduce you to Ottawa lenders specializing in multi-unit financing.
