Can you add a secondary suite to your property in HRM in 2026?
Yes. Across Halifax Regional Municipality's Urban Service Area — anywhere you have municipal water and sewer — you can now add up to four units on a single residential lot as-of-right, with no rezoning or discretionary development agreement required. That can mean a main house plus a basement apartment plus a backyard suite, or a duplex plus a backyard suite. You can also apply for Halifax's Second Unit Incentive Program (SUIP), which offers up to $13,000 in non-repayable grant money per unit toward water and wastewater costs — but the application deadline is October 11, 2026.
I'm Johnny Dulong, Family Real Estate Advisor with EXIT Realty Metro in Halifax, Nova Scotia, licensed REALTOR® (NS #NA5059). I've been helping homeowners and investors across Halifax Regional Municipality for 24 years. With mortgage renewals squeezing a lot of 2020 and 2021 buyers right now, a secondary suite is one of the few moves that can meaningfully change your monthly numbers — and HRM just made it easier to build one.

If you've been weighing whether to add a basement apartment or a backyard suite to your HRM property, 2026 is the most favourable year this has been in a long time — for two separate reasons. The zoning got easier, and there's grant money attached with a hard deadline.
Here's what's actually changed, and what it means for your numbers.
WHAT CHANGED: FOUR UNITS AS-OF-RIGHT
Halifax Regional Council's zoning reform now permits up to four units on a single lot, as-of-right, anywhere within the Urban Service Area — the parts of HRM serviced by municipal water and sewer. As-of-right means exactly what it sounds like: if your project fits within the rules, you go straight to a building permit application. No rezoning application, no public hearing, no discretionary approval from Council.
What counts toward your four units is flexible. A single-family home plus a basement apartment plus a backyard suite is three. A legal duplex plus a backyard suite is also within the limit. The combination is up to you, within the unit cap and the specific rules for each unit type.
Backyard Suite Specifications
If your plan includes a detached backyard suite, the as-of-right rules cap it at roughly 90 square metres (approximately 968 square feet) of floor area — comfortably large enough for a one- or two-bedroom unit — with a height limit and one backyard suite permitted per lot. Setback, parking, and servicing requirements still apply, so confirm the specifics for your lot with HRM's planning department or a designer familiar with the current bylaw before you finalise a design.
THE SECOND UNIT INCENTIVE PROGRAM (SUIP): WHAT THE GRANT ACTUALLY COVERS
This is the part most property owners miss: HRM isn't just allowing more units, it's paying toward the cost of servicing them.
The Second Unit Incentive Program combines two grants:
Halifax Water Fees Grant — covers a portion of the water and wastewater connection fees associated with adding a unit
Water and Wastewater Infrastructure Grant — covers up to $10,000 toward the infrastructure costs of servicing the new unit
Combined, eligible property owners can receive up to $13,000 per unit, non-repayable, toward those specific costs. This is a contribution toward servicing costs — not toward construction or finishing costs. Budget your renovation or build separately.
What Council Changed on January 27, 2026
Regional Council approved a set of updates to SUIP that materially widened the program:
Eligibility expanded to include non-profit organisations that own qualifying properties, not just individual homeowners
Multiple units per property may now be eligible for funding, subject to land use and servicing requirements — previously the program was understood to apply per property rather than per unit
Application deadline extended to October 11, 2026
Construction completion deadline extended to April 1, 2027, giving approved applicants more runway to finish the build after their application is approved
If you've been on the fence, the deadline is the part that should move you off it. Grant programs like this typically aren't renewed indefinitely — apply while the window is open, even if your construction timeline runs into next year under the extended completion deadline.
WHY THIS MATTERS FOR YOUR NUMBERS RIGHT NOW
Three things are happening in the Halifax market at the same time, and a secondary suite sits at the intersection of all of them.
First, a lot of HRM buyers who locked in ultra-low fixed rates in 2020 and 2021 are renewing in 2025 and 2026 at considerably higher rates, and feeling the payment shock directly. A rented secondary suite generates monthly income that can offset a meaningful share of a higher renewal payment.
Second, rents in HRM have moved up substantially. Asking rents for new two-bedroom leases in Halifax are running at a median of $2,550 per month as of April 2026, according to Door Insight's monthly market report. That's real, durable cash flow against a unit that, until recently, may not have been legal or practical to build under the old zoning rules.
Third, the inventory and pricing environment has normalised compared to the frenzy of a few years ago, with conditions returning to offers and price reductions becoming a routine part of the market. That's relevant here because it means your renovation dollars are competing in a calmer market — contractors and trades have more capacity than they did at the peak, which can help with both pricing and scheduling for a secondary suite build.
WHAT TO CONFIRM BEFORE YOU COMMIT
A few things worth nailing down before you sign a contractor or submit a permit application:
Confirm your lot's exact entitlement. As-of-right rules are bylaw-specific and lot-specific — confirm setbacks, servicing capacity, and your specific unit count with HRM planning staff before finalising design.
Talk to your lender about how the build will be financed, and how an appraiser will treat the added unit and its income potential. A refinance or construction draw mortgage may be involved, and the appraisal will look different than a standard purchase appraisal.
Ask your accountant about the tax treatment of the rental income and any HST implications on construction costs — this varies by your specific situation.
Check whether your existing mortgage allows secondary suite construction without triggering a renewal or amendment, particularly if you're mid-term.
If you're financing the build through a refinance, the appraiser's number matters as much as the permit. A low appraisal can change your numbers significantly — for a full guide on how the appraisal process works and what your options are when the number comes in below expectations, see the low appraisal guide.

If you're approaching this as a longer-term investment property strategy rather than a one-off suite addition, the broader investor playbook for HRM covers financing structure, cash flow modelling, and multi-unit considerations in more depth.

And if you're trying to figure out what your property is worth today — before or after adding a unit — a proper market analysis is the place to start, not an online estimate.

A secondary suite is a meaningful project — permits, servicing, financing, and a grant application with a real deadline all have to line up.

FREQUENTLY ASKED QUESTIONS
Can I add a secondary suite to my property in HRM in 2026?
In most cases, yes. Anywhere in HRM's Urban Service Area — areas with municipal water and sewer — you can add units up to a total of four per lot as-of-right, meaning no rezoning or discretionary approval is required if your project fits the rules. Backyard suites are capped at roughly 90 square metres of floor area, with one permitted per lot. Confirm your specific lot's servicing capacity and setbacks with HRM planning before finalising a design.
How much does Halifax's Second Unit Incentive Program (SUIP) grant cover?
SUIP combines a Halifax Water Fees Grant with a Water and Wastewater Infrastructure Grant of up to $10,000, for a combined total of up to $13,000 per eligible unit. The money is non-repayable and goes toward water and wastewater servicing costs specifically — it does not cover general construction or finishing costs. Regional Council expanded the program on January 27, 2026 to allow multiple units per property to be eligible, subject to land use and servicing requirements.
What's the deadline to apply for the SUIP grant?
Regional Council extended the application deadline to October 11, 2026, as part of a set of program changes approved on January 27, 2026. The construction completion deadline for approved applicants was also extended to April 1, 2027. Confirm current details directly with HRM before applying, as program terms can change.
Do I need a development agreement to build a backyard suite in Halifax?
If your project fits within HRM's as-of-right rules — unit count, size, setbacks, and servicing — you do not need a discretionary development agreement or rezoning approval, and can apply directly for a building permit. Projects that exceed the as-of-right limits, or that don't meet servicing requirements, may still require a different approval path.
Will a secondary suite increase my property taxes or affect my home's resale value?
Adding a secondary suite can affect your property's assessed value, since PVSC assessments account for additional living space and income-producing potential — though the actual tax impact varies by property and should be confirmed with PVSC directly. On resale, a legal, permitted secondary suite is generally viewed as an asset by buyers and lenders because it adds rental income potential. Asking rents for new two-bedroom leases in Halifax were running at a median of $2,550 per month as of April 2026, which illustrates the income case — but the actual effect on your specific home's value depends on your property, your market, and how the unit was built and permitted.
