In Halifax, ER-3 zoning allows homeowners with lots under 375 m² to add secondary suites without strict unit limits. This zoning focuses on building dimensions - like height, setbacks, and lot coverage - rather than capping the number of units. You can build single-unit, two-unit, semi-detached, three-unit homes, or townhomes, all with secondary suites. Key rules include:
- Height limits: 8–11 metres
- Setbacks: 1.25 m (side), 6 m (rear), 0.5–4.5 m (front)
- Secondary suite size: Up to 80 m² inside the main home or 90 m² for backyard suites
No extra parking is required, and the permit process is straightforward. Adding a secondary suite can generate rental income, with two-bedroom units renting for $1,950–$2,100/month. Efficient design, like open layouts and vertical storage, helps maximize small spaces. For smooth construction, fixed-price contracts and integrated design-build methods are recommended.
ER-3 zoning supports affordable housing and urban infill while offering flexibility for property owners to make the most of smaller lots.
What To Consider Before Building Backyard Suites In Halifax
ER-3 Zoning Rules for Small Lots
Halifax's ER-3 zoning provides a framework for developing secondary suites on lots smaller than 375 m². It outlines specific rules about what you can build, where you can build it, and how much space it can occupy. Let’s dig into the permitted building types and lot coverage to better understand the possibilities.
Allowed Building Types and Lot Coverage
Under ER-3 zoning, you can construct single-unit, two-unit, semi-detached, three-unit dwellings, and townhomes. Each of these can include a secondary suite, offering an opportunity for additional rental income [1][2].
This zoning is tailored for areas near transportation links, making it ideal for urban infill projects. With infrastructure already in place, tenants benefit from easy access to transit and other amenities [1][2].
Lot coverage rules depend on the size of the lot and the type of development. These regulations aim to balance the need for green space with the desire to maximize the use of compact urban lots.
For specifics on height and setback requirements, keep reading to refine your project plans.
Height, Setback, and Design Requirements
ER-3 zoning sets clear guidelines for building dimensions and placement on your property. Maximum building heights range from 8.0 to 11 metres, making it possible to construct multi-storey homes that accommodate both primary and secondary suites [2].
Setback requirements are equally important:
- Minimum side yard setback: 1.25 metres for buildings up to 4.5 metres tall.
- Minimum rear yard setback: 6.0 metres.
- Minimum front yard setback: Typically between 0.5 and 4.5 metres [2].
These rules help you make the most of your lot while staying within the zoning framework.
Another advantage? ER-3 zoning generally requires only a permit, without the need for site plan approval [2]. This simplified process saves time and money, making it easier to move forward with your secondary suite project.
How No Unit Caps Work
One standout feature of ER-3 zoning is its focus on building form rather than unit limits. This approach is particularly advantageous for small lots, as it allows for greater flexibility and higher rental potential [1][2].
Instead of restricting the number of units, the zoning regulations emphasize physical parameters like lot coverage, height, and setbacks. As long as your project fits within these guidelines, you can include secondary suites within the building envelope [1][2].
The Centre Plan, which governs ER-3 zoning, encourages the creation of affordable housing by supporting infill developments, secondary suites, and backyard suites [1]. This policy acknowledges that even small lots can play a significant role in addressing Halifax's housing needs when the focus shifts to building form.
For lots under 375 m², this flexibility opens up creative design opportunities. By working with knowledgeable builders, property owners can develop layouts that maximize both living space and rental income, all without being held back by outdated unit restrictions.
How to Add Secondary Suites on Small Lots
Adding a secondary suite to a small lot in Halifax under the ER-3 zoning guidelines requires careful planning. You'll need to understand zoning rules, choose a design that fits the regulations, and navigate the permit process. For lots under 375 m², these steps are essential to ensure everything goes smoothly.
Check Your Zoning and Lot Size
The first step is to confirm your property’s zoning. Use HRM's online zoning map to determine if your lot is designated as ER-3. This tool also highlights any overlays that might impact your project. To qualify for a 1-4 unit dwelling with a secondary suite, your lot must be at least 325 m² [2].
It’s also important to check for any additional restrictions tied to your property. You can call 311 or visit the HRM Planning & Development office to get clarity on specific rules that may apply [4].
Next, evaluate your lot’s current coverage and available space for expansion. Small lots often have limited room, so understanding these constraints early will save you time and effort. Once you’ve confirmed the zoning and assessed your lot’s limits, you can start planning the type of suite that works best for your property.
Choose a Suite Type That Fits the Rules
Once you’ve reviewed your lot’s restrictions, it’s time to decide on the type of secondary suite you want to add. There are two main options: secondary suites within your main home or backyard suites as separate structures. Each comes with its own set of size limits and design considerations.
- Secondary suites are fully integrated into your existing home, such as a basement apartment or a converted upper floor. These units are capped at 80 m² and must meet the same setback and height rules as your main house [3].
- Backyard suites, on the other hand, are stand-alone buildings. They can be up to 90 m², although some areas limit the footprint to 60 m² [3]. These structures offer more flexibility in design, but accessory building bylaws may impose additional restrictions [3][4].
If space is extremely tight, consider a "tiny home" approach for a backyard suite. Units under 37 m² can still generate rental income while meeting the National Building Code [3][4].
One advantage of both options is that additional parking is not required, which is a big plus for smaller lots [3][4]. However, keep in mind that you’re limited to either one secondary suite or one backyard suite per property - you can’t have both [4].
Navigate the Permit Process
With your design in place, the next step is to apply for the necessary permits. Start by submitting a building permit application through HRM’s online customer portal. You’ll need to include detailed construction and site plans that demonstrate compliance with the Building Code [5].
During the application process, your secondary suite will be assigned a separate civic address from your main home [5][4]. This makes rental management easier and ensures tenants receive their mail without issues.
The permit process includes multiple inspections at key stages of construction, such as foundation, framing, electrical, plumbing, and insulation. These inspections are crucial for ensuring your project meets code requirements. Once everything is complete, you’ll need an Occupancy Permit to confirm the suite is safe and liveable before you can rent it out [5].
Keep in mind that the permit process can take time, especially if your design is complex or pushes the limits of what’s allowed. Working with experienced builders who understand Halifax’s regulations can help avoid unnecessary delays or costly revisions.
Building on Small Lots: Design and Construction
Creating secondary suites on Halifax lots under 375 m² requires careful planning to make the most of limited space while adhering to ER-3 zoning regulations. Thoughtful design and efficient construction can turn even the smallest urban lots into profitable rental opportunities.
Layout Ideas for Secondary Suites
When working with small spaces, smart design choices can make a big difference. Open-concept layouts are a great way to create an airy, spacious feel. By combining the kitchen, dining, and living areas into one open space, you not only save on construction costs but also make the suite feel less confined.
Vertical storage solutions are another must. Think under-stair storage, high-mounted cabinets, or furniture that serves multiple purposes. These ideas help maximize every inch of available space. For existing homes, converting underused areas like basements into secondary suites is an efficient way to add rental units without expanding the home's footprint.
If you're considering a two-bedroom layout, a split design - where the bedrooms are separated by a central living area - offers added privacy for tenants. This setup can attract more tenants and generate higher rental income compared to a single-bedroom unit.
Tenant privacy is also enhanced by providing separate entrances. For instance, a backyard suite with its own entrance away from the main house creates a sense of independence. Similarly, a basement suite with an external entry ensures the main residence remains private.
The kitchen is another area where thoughtful design pays off. Compact options like galley kitchens or L-shaped layouts work well in tight spaces. Including full-size appliances, even in smaller kitchens, can appeal to tenants and justify higher rental rates.
Once you’ve nailed down the layout, the next step is ensuring a smooth and cost-effective construction process.
Construction Methods That Save Time and Money
Efficient construction is critical to keeping your project on track and within budget. Disorganized construction schedules can lead to delays and higher costs, so a well-coordinated approach is key.
One of the most effective methods is integrated design-build construction, which brings designers, contractors, and other professionals together as a single team. This approach simplifies communication, reduces errors, and can significantly shorten project timelines - sometimes cutting the standard 12–18 months down to just six months.
Opting for fixed-price contracts is another smart move. While cost-plus arrangements might seem appealing initially, they often result in unexpected budget increases. Fixed pricing, on the other hand, gives you a clear understanding of total costs before construction begins.
Advanced scheduling systems also play a role in avoiding delays. Coordinating trades and material deliveries ensures the project stays on track. Adding daily progress documentation, such as photo updates, allows you to monitor the build remotely, address issues early, and keep a detailed record for insurance or warranty purposes.
To maintain high construction standards, a quality verification system is essential. For example, having a Professional Engineer perform multiple inspections during the build ensures everything meets rigorous standards. Choosing your final inspector can also give you peace of mind and may even come with an extended warranty.
Solving Parking, Access, and Utility Issues
Small urban lots often come with unique challenges, but strategic planning can help you navigate them. For example, ER-3 zoning does not require additional parking, which allows you to dedicate more space to the suite itself.
Fire access is an important consideration, especially on tight lots. Maintaining clear routes for emergency vehicles is crucial, but this can often be achieved by placing suites near existing driveways, minimizing the impact on your buildable area.
When it comes to utility connections, careful planning can save you from costly surprises. Secondary suites within the main home often tie into existing electrical, water, and sewer systems, though upgrades may be needed. Backyard suites, on the other hand, typically require separate utility lines, which should be planned early to avoid expensive rework.
Older homes may need electrical service upgrades to handle the extra load of a secondary suite. It’s important to assess whether your current panel can meet the increased demand or if an upgrade is necessary.
For sewer and water connections, early planning is critical. Running new lines near driveways or existing structures requires precise coordination to avoid later disruptions. Proper drainage is equally important. Installing effective stormwater management systems protects neighbouring properties and ensures compliance with local regulations.
Finally, don’t overlook Internet and cable connections during construction. Pre-installing these services is a cost-effective way to meet modern tenant expectations and avoid the hassle of retrofits later on.

Getting the Best Rental Returns
Boosting rental income on small Halifax lots zoned under ER-3 calls for a focused strategy that balances smart unit design, tenant-friendly features, and careful cost management.
Unit Types and Expected ROI
Two-bedroom units tend to deliver the best rental returns. In Halifax, these units typically rent for $1,950–$2,100 per month. Adding a secondary suite to an existing home is often a more affordable way to generate rental income compared to constructing a detached backyard suite. However, backyard suites - while more expensive to build - can command higher rents due to added privacy and features like separate entrances. Even with the 60 m² maximum building footprint allowed on small lots in areas like Halifax Peninsula and Downtown Dartmouth, clever design can still accommodate comfortable two-bedroom layouts [6].
To achieve a strong annual ROI - typically between 12% and 20% - it’s crucial to keep construction costs per unit efficient while ensuring the property appeals to renters. On small lots, where land costs are already accounted for, this balance becomes even more critical.
Next, let’s explore features that can attract quality tenants and justify premium rents.
Features That Attract Good Tenants
Energy-efficient upgrades not only cut operating costs but also appeal to tenants. Installing features like triple-pane windows and ductless heat pumps ensures lower utility bills and provides quiet, consistent heating - both of which enhance tenant satisfaction.
In-suite laundry is another must-have. Tenants are often willing to pay more for units with washer and dryer access. Modern kitchens with quartz countertops, stainless steel appliances, and full-size features like dishwashers also create a strong impression during showings. These details signal quality construction and help attract renters who are willing to pay a premium.
For added convenience and security, consider smart home features like keyless entry and programmable thermostats. Separate entrances are especially desirable for secondary suites, offering tenants privacy and independence. Thoughtful storage solutions - like built-in closet organizers, under-stair storage, and well-designed pantries - further improve the functionality of compact spaces, making them more appealing to renters.
Construction Costs and Financing Options
Striking the right balance between attractive features and controlled construction costs is key to maintaining healthy rental returns. Opting for fixed-price contracts can help avoid unexpected cost overruns - common with cost-plus contracts, which can inflate expenses by 30-60%. Fixed pricing also simplifies ROI calculations and financing plans.
In Halifax, the average cost to build quality rental units is about $160,000 per unit for projects with four or more units. This estimate includes energy-efficient features like heat pumps and triple-pane windows, along with high-quality finishes that appeal to discerning renters.
For projects meeting advanced energy efficiency standards, CMHC MLI Select financing offers favourable terms, such as up to 95% financing with a 50-year amortization period. While these projects may cost closer to $200,000 per unit, the financing benefits can significantly improve cash flow from the outset.
To ensure units are ready for immediate occupancy, property owners should budget an additional $15,000 per unit for appliances and other move-in essentials. Timely project completion is also critical - construction delays can cost property owners the equivalent of one month’s rent per unit, or approximately $1,950 to $2,100. Using an integrated construction approach that streamlines trades and material coordination can cut timelines from the standard 12–18 months to around 6 months, allowing units to hit the rental market faster.
The key to maximizing rental returns lies in combining high-quality construction with careful cost control. Avoid cutting corners on tenant-facing features like flooring, fixtures, and appliances - these investments help maintain strong rental rates and low vacancy levels.
Conclusion
For Halifax property owners with lots under 375 m², ER-3 zoning opens the door to generating rental income by allowing 4–8 residential units, depending on the lot size[7].
To bring your project to life, follow these three key steps. First, confirm your ER-3 zoning and service capacity with Halifax Water to ensure your lot meets the requirements[7][8]. Second, design your development within the 11-metre height limit, adhere to lot coverage restrictions, and include street-facing entrances with appropriate windows and doors for a welcoming appearance[7]. Third, take advantage of the absence of minimum parking requirements to maximise your buildable space, while ensuring essential features like screened waste areas are included for developments with four or more units[7].
Looking ahead to 2025, policy updates - such as relaxed rules for secondary suites and the potential for shipping container conversions - signal growing support for creative housing solutions[8]. For small-lot owners, this creates a timely opportunity to make the most of the current zoning regulations before any changes take effect.
