Halifax Fourplex Development: Now Legal on ER-3 Properties

published on 10 August 2025

Property owners in Halifax can now legally build fourplexes on ER-3 zoned lots, thanks to new zoning rules under the 2025 Regional Plan. This change aims to address the city's growing housing demand and offers opportunities for rental income and long-term property value growth. Key details include:

  • ER-3 Zoning Flexibility: Allows up to 8 units per lot, including fourplexes, with a maximum building height of 12 metres (~3 storeys).
  • No Minimum Parking Requirements: Easier development in urban and suburban areas.
  • Construction Costs: Estimated at $160,000–$200,000 per unit, depending on energy efficiency goals.
  • Financing Options: CMHC MLI Select offers up to 95% financing with extended amortization for energy-efficient projects.
  • Rental Income Potential: Two-bedroom units rent for $1,950–$2,100/month, offering annual returns of 12%–20%.

The introduction of these rules simplifies the process for property owners to develop multi-unit housing, helping alleviate Halifax's housing shortage while generating steady rental income. Integrated construction methods, like those offered by Helio Urban Development, ensure fixed costs, faster timelines, and reduced risks compared to fragmented approaches.

ER-3 Zoning Rules for Fourplex Construction

Before diving into your fourplex construction project, it's essential to understand the ER-3 zoning rules. These regulations outline important factors like building height, density, and parking requirements, which can significantly impact your plans.

What is ER-3 Zoning?

ER-3 zoning is Halifax's most flexible residential designation under its updated planning framework. This zoning allows property owners to construct up to eight units on a single lot. These units can include duplexes, townhomes, small apartment buildings, or condos, making it a versatile option for fourplex developments [1].

"The ER-3 zone would become the most common in residential areas because it's the most flexible. It would allow up to eight units of duplexes, townhomes, small apartments or condos to be built on a single lot." - Haley Ryan, Reporter, CBC News [1]

With the maximum unit count established, the next step is to consider the specific construction guidelines.

Construction Requirements for Fourplexes

ER-3 zoning provides clear construction standards that are crucial for planning and approval. For example, buildings in this zone can reach a height of up to 12 metres, which is roughly three storeys [1]. This height allowance gives developers room to design functional and aesthetically pleasing fourplexes.

One notable change under ER-3 zoning is the removal of minimum parking requirements in many areas. This shift eliminates a common barrier to developing smaller lots, opening up new possibilities for urban housing [1].

"There would also be no minimum parking requirements for new development in the regional centre or the suburbs." - Haley Ryan, Reporter, CBC News [1]

While the rules around setbacks and minimum lot sizes aren't explicitly detailed, these typically depend on the neighbourhood and local infrastructure. It's important to review these elements based on the specific location of your project to ensure compliance with local standards.

How to Make Money with Fourplex Developments

The updated ER-3 guidelines have made fourplex developments a more attractive option for generating financial returns. In Halifax, the fourplex market promises steady rental income and opportunities for building long-term wealth. With the right strategy for construction and market positioning, these properties can deliver strong returns while offering a diversified income stream.

Rental Income and ROI in Halifax

Helio Urban Development's two-bedroom units rent for $1,950–$2,100 per month, providing an annual return of approximately 12%–20%. With four units in a single property, landlords benefit from a diversified income source that remains resilient even if one unit becomes vacant.

Maximizing rental income starts with carefully managing construction costs to ensure profitability.

Construction Costs and Financing Options

Keeping construction costs under control is key to boosting returns. Helio offers a fixed-price model for building fourplexes, with each unit costing $160,000 to construct. This brings the total cost to $640,000 and includes high-quality finishes such as engineered hardwood floors, quartz countertops, triple-pane windows, and individual ductless heat pumps.

For those looking to build energy-efficient units, Helio’s CMHC MLI Select tier offers an alternative. These units cost about $200,000 each to construct but qualify for up to 95% financing with extended amortization periods. This financing structure ensures immediate positive cash flow once the units are rented.

Fixed-price contracts eliminate the uncertainty of budget overruns, a common issue in traditional construction projects. Helio’s integrated delivery model also guarantees a six-month construction timeline - far shorter than the usual 12–18 months - allowing rental income to start flowing sooner.

To make the units rental-ready, an additional $15,000 per unit covers essentials like appliances, smart home technology, and window coverings. This package not only helps attract high-quality tenants but also ensures there are no delays between project completion and generating rental income.

Integrated vs Fragmented Construction Methods

When planning to build a fourplex on your ER-3 property, the construction method you choose can have a big impact on your project's profitability. The decision often boils down to choosing between hiring multiple contractors for different phases or working with an integrated design-build company. These two approaches can lead to very different outcomes. Let’s explore how Helio’s integrated model addresses the common challenges of traditional construction.

Problems with Fragmented Construction

Traditional construction typically involves hiring separate professionals for each stage - architects, engineers, general contractors, and subcontractors. While this might seem straightforward, it often creates serious coordination issues. In fact, property owners can lose an average of $47,000 per project due to inefficiencies. Why? Misaligned designs, engineering missteps, and permitting delays frequently slow things down. These inefficiencies often lead to budget overruns of 30–60% and extend project timelines to 12–18 months or more. Not only does this increase your costs, but it also delays the start of rental income, which can be a significant financial setback.

Advantages of Integrated Design-Build

Integrated construction takes a different approach by bringing everyone - planners, architects, engineers, and builders - under one roof. This unified model solves many of the problems that fragmented methods create.

  • Single accountability: With one company managing the entire project, there’s no finger-pointing. Helio, for example, guarantees a six-month timeline and even includes delay penalties of up to $1,000 per day.
  • Fixed pricing: Because the same team handles both design and construction, you get a clear, upfront cost. Helio offers a fixed price of $160,000 per unit, which eliminates the risk of unexpected change orders or budget blowouts.
  • Streamlined processes: Integrated companies rely on repeatable designs and standardized workflows to keep everything on track. Proven floor plans and efficient construction methods help reduce risks and speed up completion.

Comparison Table: Fragmented vs Integrated Construction

Here’s a quick breakdown of how fragmented and integrated methods stack up:

Feature Fragmented Construction Integrated Construction
Timeline 12–18 months typical 6 months guaranteed
Budget Control 30–60% overruns common Fixed price, no overruns
Accountability Multiple parties with fragmented oversight Single company responsibility
Coordination Multiple contractor management Internal team coordination
Quality Control Varies by individual contractor Systematic quality verification
Design Efficiency Custom designs tailored to each project Repeatable, proven designs
Risk Management Owner bears significant risks Builder guarantees delivery
Communication Multiple contacts to manage Single point of contact

Choosing between fragmented and integrated construction is a critical decision. While fragmented methods often lead to delays, cost overruns, and miscommunication, integrated design-build companies like Helio provide a smoother, more predictable process. By addressing the core issues of coordination, budgeting, and timelines, they help ensure your fourplex project becomes a profitable investment instead of a financial headache.
