Dartmouth's updated ER-3 zoning now permits up to 8 rental units on lots of 600 square metres or more. This change tackles Halifax's housing shortage, with the city aiming to add 71,000 units over time. ER-3 zones, found near transit and amenities, allow for low-rise developments like duplexes, townhomes, and small apartments. Property owners can increase land value and earn steady rental income, with average rents in Dartmouth reaching C$2,550/month. With no parking minimums and streamlined approvals, this presents a strong opportunity for small-scale builders and investors.
Key Takeaways:
- Lot Size: Minimum 600 m² for 8 units; 325 m² for 1–4 units.
- Building Height: Up to 12 metres.
- Rental Demand: Average rent in Dartmouth is 21% higher than the national average.
- Approval Process: Simplified with Halifax investing C$79M in planning resources.
For property owners, this is a chance to meet strong housing demand while growing their investment potential.
ER-3 Zoning Rules for Multi-Unit Buildings
ER-3 zoning regulations are crafted to help property owners make the most of their investments while supporting higher-density housing that fits seamlessly into existing neighbourhoods. Let's break down the key rules, including lot sizes, design standards, and accessibility considerations.
Lot Size and Unit Limits
In Dartmouth's ER-3 zones, up to eight housing units can be built on a single lot. These units can take the form of duplexes, townhomes, small apartment buildings, or condos, with specific lot size and configuration guidelines outlined in the draft Centre Plan and Land Use By-law [3]. These zones are often located along major transit routes or areas where townhomes were previously allowed, giving residents easy access to public transit and local amenities.
Building Design Requirements
Design standards in ER-3 zones are focused on maintaining a balance between density and liveability. Buildings can be as tall as 12 metres, with lot coverage ranging from 35% to 50%. Setback rules ensure privacy, allow for utility and service access, and provide necessary clearance for emergency vehicles [2][3]. This approach gives architects the freedom to create designs that suit the local community while adhering to these practical guidelines.
Parking and Accessibility Rules
Halifax has removed minimum parking requirements for new developments in both the regional centre and suburban areas [2]. This shift enables developers to allocate more space for housing, outdoor spaces, or landscaping. While parking is now optional, developers can include features like bicycle storage and secure, well-lit access points if desired.
Accessibility standards, as outlined in Nova Scotia's building code, are non-negotiable. These include elevators, step-free entrances, wider doorways, accessible bathrooms, non-slip flooring, proper lighting, and clear sight lines [4]. These features not only meet legal requirements but also make properties more appealing to a broader range of residents.
How to Build an 8-Unit Property: Step-by-Step Process
Creating an 8-unit property on ER-3 zoned land involves meticulous planning and coordination. By following a structured process - from initial assessment to construction - you can sidestep common issues like missed deadlines and budget overruns that often arise from disjointed project management.
Step 1: Property Assessment and Planning
Start by confirming that your lot meets the specific requirements for ER-3 zoning. While this zoning allows for multi-unit dwellings, the rules can vary depending on your property's location and size. Generally, an 8-unit development will need a lot of at least 600 square metres to accommodate the building, parking spaces, and required setbacks [3]. You'll also need to ensure your lot’s coverage allowance falls within the 35% to 50% range [3].
Location plays a critical role since ER-3 zones are often found near major transit routes or in areas previously designated for townhomes [3]. To ensure your lot is suitable, hire a qualified planner or architect to conduct a feasibility study. This study should evaluate utility access, drainage, and how the development might impact or be affected by neighbouring properties. Once you confirm your lot’s potential and complete the planning phase, you can move forward with obtaining the necessary municipal permits.
Step 2: Municipal Permits and Approvals
For multi-unit projects in the Halifax Regional Municipality (HRM), securing the right permits is essential. Typically, you’ll need a development permit supported by detailed plans that align with the Centre Plan and Land Use By-law.
Reach out to HRM Planning & Development (planhrm@halifax.ca) early in the process to clarify property-specific regulations. If your project includes variations from standard by-law requirements, a Site Plan Approval may also be necessary. Prepare comprehensive documentation, including site plans, building elevations, parking layouts, and landscaping designs, to facilitate a smoother review process. Keep in mind that municipal approvals can take several weeks, so detailed and accurate submissions are crucial. Once permits are in hand, you can turn your attention to construction.
Step 3: Construction Management
The construction phase is where many projects encounter delays and cost overruns, often due to fragmented management. When multiple professionals work independently, coordination issues can arise, stretching timelines and increasing expenses.
To avoid these pitfalls, adopt an integrated construction management approach. This method brings all professionals - architects, engineers, contractors - under a single leadership structure, ensuring smoother coordination. Without this unified strategy, timelines can balloon from the planned 8 months to 18 months or more. Regular inspections by a Professional Engineer and daily progress monitoring (including photo updates) help maintain quality and address issues promptly.
A well-organized construction process not only ensures timely completion but also allows you to start generating rental income as planned. By sticking to a systematic management strategy with clear timelines and guaranteed completion dates, you can protect your investment and keep your project on track.
Design-Build vs Multiple Contractor Approach
When planning an 8-unit property on ER-3 zoned land, one of the biggest decisions you'll face is choosing between a design-build firm or hiring multiple separate contractors. This choice can have a major impact on your project's timeline, budget, and overall stress level.
Let’s break down why this decision matters, especially for ER-3 developments.
Design-Build Advantages
The design-build model brings everything under one roof - planners, architects, engineers, and builders all work as one team. This eliminates the usual coordination headaches. With one company handling the entire process, you can lock in a fixed price before construction even begins, avoiding the budget overruns that often occur with traditional methods (which can range from 30–60%).
This approach also speeds things up. Overlapping phases and having a single decision-maker keep the project moving, while issues are resolved quickly. Plus, quality control is more reliable because one company is responsible for every part of the process.
Challenges of Using Multiple Contractors
When you hire separate contractors, coordination can become a nightmare. Misaligned schedules between electricians, plumbers, and other trades lead to delays. Miscommunication about design changes can cause errors, and competition for workspace or power sources can slow productivity.
Managing payments is another hassle - you’ll juggle multiple invoices, warranties, and contract terms. On top of that, inconsistent safety standards among contractors can increase liability risks and even halt work entirely.
Construction Method Comparison
| Factor | Design-Build | Multiple Contractors |
|---|---|---|
| Budget Control | Fixed price with no overruns | Cost-plus with frequent overruns |
| Timeline Management | 6–8 months with guarantees | 12–18 months with delays |
| Communication | Single point of contact | Coordinating 6+ separate companies |
| Quality Assurance | Unified standards and warranty | Multiple warranties and standards |
| Problem Resolution | Internal coordination | External mediation required |
Collaboration plays a huge role in project success. Studies show that 46% of collaboration-focused projects come in under budget, compared to just 10% of other projects [5]. Additionally, 24% of collaboration-driven projects finish ahead of schedule, compared to only 6% of typical projects [5]. Notably, 43% of the most trusted construction firms prioritize collaboration in their project management approach [5].
For ER-3 developments, where rental income depends on finishing on time, the predictability of a design-build approach can be a game-changer. A streamlined timeline means you can start earning rental income sooner, making this method a smart financial choice.

Rental Income and ROI for 8-Unit Properties
Owning an 8-unit ER-3 property in Dartmouth can be a rewarding investment when tenant needs, market trends, and upkeep are managed effectively. With Dartmouth's rental market showing strong demand and rents sitting 21% higher than the national average[7], property owners who take a strategic approach can see impressive returns. Thoughtful design choices play a direct role in tenant satisfaction and overall profitability.
Tenant-Focused Design Features
To attract and retain quality tenants, properties must meet modern expectations. For example, in-suite laundry is a must-have amenity for many renters. At 222 Portland Street in Dartmouth, the inclusion of in-suite washers and dryers has proven to be a key draw for tenants in one- and two-bedroom units.
Another feature tenants value is modern kitchens with high-quality finishes. At the same Portland Street property, designer kitchens equipped with built-in dishwashers and microwaves not only add convenience but also justify higher rents.
Private outdoor spaces, like well-designed balconies, further enhance the appeal of a rental unit. Beyond aesthetics, factors like security, cleanliness, and responsive property management are critical for retaining tenants and reducing turnover.
Dartmouth Rental Market Data
Dartmouth's rental market provides a solid foundation for 8-unit developments. As of August 2025, the average rent across all property types in Dartmouth hit C$2,550 per month, reflecting steady growth[7].
Two-bedroom units, a common configuration for 8-unit properties, command an average rent of C$2,091 per month, with some central Dartmouth locations reporting rents as high as C$2,700[6][8]. These variations often depend on the building's quality, amenities, and location.
The market continues to grow, with rents increasing by C$750 over the past year, showcasing strong demand[7]. More conservative estimates report a smaller growth of 0.8%, which adds about C$14 per month to average rents[6]. For context, in Halifax's broader market, two-bedroom units saw a 3.8% rent increase, reaching C$1,707 in 2024. Dartmouth's higher rates reflect its growing desirability[1].
Dartmouth's rental rates also benefit from the region's economic and population growth. With rents 21% above the national average[7], the city's appeal continues to rise. Local authorities are focusing on "missing middle" housing solutions - like 8-unit developments - to address supply shortages[1]. Additionally, Nova Scotia's rent control measures, which cap annual rent increases at 5%, provide stability for both landlords and tenants[1].
Property Management and Maintenance
Effective property management and maintenance are essential for protecting returns over the long term. A good rule of thumb is to allocate 50% of monthly rental income for operating costs. For an 8-unit property generating C$16,728 monthly, this means setting aside roughly C$8,364 for expenses like maintenance, insurance, and management.
It’s also wise to plan for major repairs or replacements by reserving 1% to 2% of the property’s purchase price annually. For a property valued at C$1.28 million, this translates to setting aside C$12,800 to C$25,600 per year[9].
Vacancy rates should also be factored in. A 5–10% vacancy rate equates to having 0.4 to 0.8 units vacant in an 8-unit property[10].
For well-managed 8-unit properties, annual returns typically range from 8% to 12% for long-term rentals, with similar cash-on-cash returns considered favourable for financed properties[11]. In Dartmouth’s thriving market, properties that combine excellent construction with tenant-focused design can achieve returns at the higher end of this range.
The secret to strong returns lies in balancing quality construction with market-appropriate rents. Skimping on construction quality often leads to higher vacancy rates and increased maintenance costs, which can quickly eat into profits. Thoughtful planning and attention to tenant needs are key to long-term success.
Getting Started with ER-3 Development
Diving into Dartmouth's ER-3 development means first confirming your property’s eligibility and assembling the right team for the job. With Halifax grappling with a housing shortage of nearly 20,000 units as of 2023 and rental vacancy rates stuck at 1.0% for three straight years, acting now puts property owners in a strong position to meet market demand[17].
Start by checking Halifax's municipal zoning maps, which are accessible through the local government's website, to ensure your property is zoned as ER-3[12]. This step is crucial to confirm your lot meets the necessary zoning requirements.
Next, focus on building a professional team that can handle the complexities of multifamily development. From navigating design and permitting to managing construction, experienced professionals are essential for a smooth process[13]. Begin permit applications early, and seek out construction experts with a proven track record in multifamily projects[14][15].
"Communication, collaboration and education between Fort Sands and the people with the vision for their unique property is vital for a successful project."
Once eligibility and a skilled team are in place, the next priority is selecting a construction strategy that ensures success. The method you choose can make or break your project. Fragmented construction often leads to budget overruns ranging from 30% to 60% and can stretch timelines from 8 months to over 18 months. Instead, consider an integrated design-build approach, which minimizes coordination issues and offers fixed pricing with guaranteed timelines.
Budget planning is another critical step. With HRM welcoming over 20,000 new residents last year and rental prices climbing by more than 11% annually, the fundamentals strongly support 8-unit developments[17]. To keep your project on track, leverage effective project management tools and delivery systems that help identify and address potential challenges early on[14][15].
Upcoming regulatory changes, effective June 13, 2024, present a unique opportunity for property owners[17]. The Housing Accelerator Fund aims to add 2,600 new housing units to HRM within the next three years, positioning ER-3 developments as a vital part of addressing the "missing middle housing" gap[17].
Success in ER-3 development boils down to three key steps: confirming your property qualifies, hiring skilled professionals who understand the approval process, and adopting a construction strategy that ensures predictable outcomes. By approaching each of these elements methodically, you can take advantage of Dartmouth’s thriving rental market while playing a role in alleviating the community’s housing challenges.
