Stormwater, Driveway & Curb-Cut Approvals in HRM: The Servicing Permits That Govern What a Lot Can Become

Zoning tells you how many units a Halifax lot can hold. It does not tell you whether the lot can be serviced — connected to municipal water, wastewater, and stormwater systems, and reached by a legal driveway across a public road. Those questions are answered by a separate set of approvals: the water permit, the right-of-way (driveway and curb-cut) permit, and the servicing engineering that sits behind both. They are routinely the most overlooked part of a multi-unit feasibility analysis, and they are where a project that looks buildable on paper can stall, shrink, or get materially more expensive.

Helio is a computation-driven real estate development company in Halifax. When we model what a parcel can realistically become, servicing is not an afterthought — it is one of the constraints we solve for, alongside the Land Use By-law, the building code, and the capital stack. This article walks through how these three approvals actually work in the Halifax Regional Municipality (HRM), in the correct order, with the costs that are verifiable against primary sources. (All figures are current as of 2026-06-23; HRM and Halifax Water update fee schedules annually, so confirm the live schedule before you budget.)

Why servicing approvals decide feasibility, not just compliance

A development lives or dies on whether the building it contemplates can physically connect to the systems around it. Three of those connections are governed by separate HRM and Halifax Water approvals:

• Stormwater and water/wastewater connections — how rain and surface water leave the site, and how potable water and sewage move to and from the building. Managed through Halifax Water's Water Permit process [1].
• Driveway access — the legal and physical right to cross the municipal right-of-way to reach your lot, governed by a right-of-way permit [1].
• Curb cuts — the modification of the existing curb, culvert, or sidewalk edge to create or move that access, which travels with the same right-of-way permit family [1].

The reason these matter at the feasibility stage and not merely the compliance stage is that they can change the answer. A required stormwater management approach may consume buildable area. A driveway-width rule can limit how many parking spaces — and therefore which unit yields — a lot can support. A constrained or contested curb cut can force a different site layout entirely. None of this shows up in a zoning lookup, which is exactly why it has to be modelled deliberately.

The water permit: stormwater, water, and wastewater connections

Stormwater is not a standalone HRM permit. It is handled as part of Halifax Water's Water Permit system, which governs how a new building connects to municipal water, wastewater, and storm infrastructure. A Water Permit is required when the new building falls within the Municipal Water Boundary [1].

The technical core of the application is a Site Servicing Plan. Per HRM's streets and services guidance, that plan shows the lot layout and building footprint, driveway location(s) and dimensions, the sewer lateral location and size, the water lateral location and size, and the existing trunk services that will serve the property [1]. For a multi-unit building, the volume of runoff from a larger roof and more paved surface is greater than a single house, so the servicing plan — and the engineering judgement behind it — carries more weight.

Sequencing matters. The Water Permit is downstream of the building permit: you work through the building-permit process first, then the servicing approval. Halifax Water also oversees the inspections that confirm the service connections are made correctly. Getting the order and the documents right is the difference between a clean review and an iterative one.

The per-unit cost that actually moves the budget

The small administrative fees attached to service connections are real but minor relative to the charge that genuinely affects a multi-unit pro forma: the Regional Development Charge (RDC), levied by Halifax Water per new unit to fund regional water and wastewater infrastructure.

As of 2026-06-23, and effective April 1, 2024 (frozen at 2023 levels under an HRM Charter amendment), the RDC is:

• Multiple-unit dwellings: $5,405.81 per unit — $1,290.77 water + $4,115.04 wastewater [2].
• Single-unit dwellings and townhouses: $8,048.66 per unit — $1,921.82 water + $6,126.84 wastewater [2].

On those numbers, a four-unit building in the multi-unit category carries roughly $21,623 in RDCs alone (4 × $5,405.81) — a figure worth carrying explicitly in any feasibility model rather than discovering at the servicing-permit stage. Note the freeze is not permanent: Halifax Water has been engaging stakeholders on an RDC increase (reported in the mid-to-high teens in percentage terms), so the per-unit charge is a moving number to re-confirm at the time you apply [3].

Driveway and curb-cut approvals: DEV-ROW vs TPW-ROW

Driveway and curb-cut work happens in the municipal right-of-way — the public land between your property line and the road — which is why it needs its own permit. HRM offers two different right-of-way permits for driveway access, and they are not interchangeable [1]:

• DEV-ROW (Development Right-of-Way) permit — used when you already have an open building permit on the property. New multi-unit construction falls here: the driveway is part of the development, so it travels under the development-stream right-of-way permit [1].
• TPW-ROW (Transportation & Public Works Right-of-Way) permit — used when there is no open building permit and you are modifying an existing driveway: moving it, widening it, or changing the curb or culvert [1].

These permits apply only to properties fronting a municipally owned road [1]. The plan you submit must show the driveway's location relative to the property lines and the right-of-way, consistent with the Site Servicing Plan.

Driveway dimensions are regulated, and they interact with unit yield. For residential properties of four units or fewer, a two-way driveway must be not less than 3 m (10 ft) and not greater than 5 m (16 ft) wide; lots with frontage greater than 18 m (60 ft) may be permitted a driveway up to 6 m (20 ft) [1]. Width limits and hard-surface rules constrain how a site lays out parking and access — which is precisely the kind of detail that determines whether a given unit count is actually achievable on a particular lot.

Curb cuts travel with the right-of-way permit

A curb cut — modifying the existing curb, culvert, or sidewalk edge to create the driveway opening — is part of the same right-of-way approval family rather than a wholly separate process [1]. Because it physically alters municipal infrastructure and ties into how surface water drains at the lot edge, it has to coordinate with the stormwater servicing on the site and with any existing utilities in the right-of-way.

Work within the public right-of-way is performed under municipal rules: HRM requires that such work be done by appropriately qualified, insured contractors, and a performance security (a deposit or a letter of credit on file with the municipality) is part of the right-of-way framework. The exact administrative fees and security amounts are set in HRM's current fee schedule and should be confirmed there directly, as they are reviewed annually [1].

How the approvals fit together — and in what order

The three approvals are interdependent, so the order is not cosmetic:

1. Confirm the zoning and the servicing context first — is the lot within the Municipal Water Boundary, on a municipally owned road, and serviceable for the unit count the zone permits? This is feasibility, not paperwork.
2. Work the building permit for the development. Building permits, inspections, and occupancy permits in Nova Scotia are administered and enforced municipally — by HRM's Planning & Development office — even though the building code itself is provincial law [4].
3. Apply for the Water Permit with the Site Servicing Plan once the building-permit stream is underway; this is the stormwater/water/wastewater connection approval [1].
4. Apply for the right-of-way permit — DEV-ROW where there is an open building permit (the multi-unit case), TPW-ROW where there is not — covering the driveway and curb cut [1].
5. Pass the inspections, including Halifax Water's service-connection inspections, before the connections are accepted [1].

Applications for these permits are submitted through HRM's online permitting portal. Submitting them out of sequence, or with an incomplete Site Servicing Plan, is the most common self-inflicted delay.

What this costs at the municipal level (verifiable figures only)

Several numbers that circulate for these approvals are not traceable to a primary source, so we don't repeat them. The figures below are the ones you can verify directly:

• Regional Development Charge: $5,405.81 per unit (multi-unit) / $8,048.66 per unit (single-unit & townhouse), effective April 1, 2024, frozen at 2023 levels (re-confirm — an increase is under engagement) [2][3].
• HRM building permit fee, new residential (4 units or fewer): charged per square metre of floor area — $4.04/m² at or above average finished grade, $3.36/m² for shallow below-grade floors (≤1.67 m), and $1.35/m² for deeper basements and garages, with a $31.25 minimum (effective April 1, 2024) [5].
• HRM building permit fee, other residential / renovations / commercial: $6.88 per $1,000 of estimated construction value, $31.25 minimum (effective April 1, 2024) [5].
• HRM demolition permit (if you are clearing an existing structure to develop): $62.50, plus possible engineering-related fees [5].

Two more budget realities sit alongside the permit fees. First, HST in Nova Scotia is 14% (5% federal + 9% provincial) as of April 1, 2025, and applies to construction inputs [6]. Second, there is no province-wide statutory deadline for permit review in Nova Scotia; HRM residential reviews are commonly described as roughly four to eight weeks and multi-unit developments as several months, but these are practitioner estimates that depend entirely on how complete the application is [7]. Building schedule contingency around servicing review — not assuming a fixed turnaround — is the conservative posture.

Where projects go wrong on servicing

The failure modes are consistent, and all of them are avoidable in the modelling stage:

• Treating servicing as a downstream formality. A stormwater approach or a constrained curb cut can change the buildable layout. Discovering that after the design is locked is expensive; modelling it first is not.
• Submitting in the wrong order or with an incomplete servicing plan. The Water Permit follows the building permit; the Site Servicing Plan must show the laterals, the trunk services, and the driveway geometry. Missing pieces mean a re-review, not a quick fix.
• Applying for the wrong right-of-way permit. DEV-ROW and TPW-ROW are not interchangeable; new construction with an open building permit uses DEV-ROW [1].
• Ignoring the per-unit development charge in the pro forma. At $5,405.81 per multi-unit dwelling, RDCs are a material line item, not a rounding error [2].
• Assuming a fixed review window. There is no legislated maximum; completeness drives the timeline [7].

How a development firm models this from the start

Because we treat servicing as a feasibility constraint rather than a permitting chore, the work happens before a shovel is contemplated. When Helio computes what a parcel can support, the same analysis that reads the zone's permitted unit yield also asks whether the lot is within the Municipal Water Boundary, what the driveway-width and curb-cut rules allow given the frontage, what stormwater management the site will likely require, and what the per-unit Regional Development Charge does to the returns. The servicing approvals then proceed in their correct sequence, with the building permit and Water Permit and right-of-way permit handled in order and the engineering documents prepared to HRM and Halifax Water standards.

The point of doing it this way is not to make the permits disappear — they are a fundamental part of building anything in HRM — but to ensure the development you commit to is the one the land can actually support, fully serviced, before the capital is at risk. Helio develops on land its clients own, computes the optimal program for the parcel, and delivers it end-to-end, with construction carried out by established builders. We publish no price of our own; the figures in this article are official HRM, Halifax Water, and federal sources, cited so you can verify them.

If you own a lot in HRM and want to understand what it can realistically become — including whether it can be serviced for the unit count the zoning allows — that is the question a feasibility study answers.
