Forum answers to this question range from "always" to "never," and both are wrong in both directions. The actual answer lives in section 56(2) of the Nova Scotia Architects Act, and it's more permissive for an ordinary house than most people expect. Here is the statute first, then what it means.
What the Act says
Nothing in this Act prevents (a) the practice of architecture by persons other than licensed architects in connection with a building as constructed, enlarged or altered, and used for one or more of the following occupancies, unless a licensed architect is otherwise required by law or by the building authority having jurisdiction over the project: (i) a one-dwelling or two-dwelling unit, (ii) of three storeys or less in buiding height, having a buiding area not exceeding 450 square metres classified as (A) residential occupancy, (B) business and personal services occupancy, (C) mercantile occupancy, or (D) low and medium hazard industrial occupancy, (iii) an assembly occupancy of not more than one storey in building height, having a building area of not more than 200 square metres, or (iv) a high hazard industrial occupancy of not more than one storey in building height, having a building area of not more than 200 square metres
Architects Act, SNS 2006, c. 12, s. 56(2)(a) — retrieved August 30, 2026 from CanLII (canlii.org/en/ns/laws/stat/sns-2006-c-12).
The spelling of "buiding" is in the statute as published — we quote legislation verbatim, typos included, rather than silently correct it.
What that means for a single house
Clause (i) is the one most homeowners care about: a one-dwelling or two-dwelling unit is exempt from the Act's licensing requirement. For a typical detached house, semi-detached or duplex, Nova Scotia does not require a licensed architect to prepare the design. The exemption is not size-limited the way clause (ii) is — a one- or two-dwelling building is exempt as such.
Two qualifications matter. First, the carve-out ends with "unless a licensed architect is otherwise required by law or by the building authority having jurisdiction" — another statute, or the authority reviewing your permit, can still require professional involvement for a specific project. Second, exemption from the Architects Act is not exemption from the Building Code: your plans must still meet code, and the permit still has to be issued.
What HRM asks for at intake
Halifax Regional Municipality's published intake for new home construction lists the documents a residential application usually needs — and notably, an architect's seal is not among them for a standard house. As published on the municipality's New Home Construction page (retrieved August 30, 2026):
- Construction Plan — floor plans showing interior layout of each floor with rooms labelled and dimensioned, fixture locations, framing member sizes and spans, and total areas; a roof plan; and a cross-section through an exterior wall from footing to roof.
- Site Plan — lot dimensions and building footprint, setbacks to property boundaries, driveway location, and watercourse or coastal buffers where applicable; service laterals, fire department connections and hydrants when the building is inside the municipal service boundary.
- Elevations — dimensions of all sides with finished grade and overall height, exterior finishes, window and door types, sizes and locations, and exterior decks, stairs, guards and handrails.
- Outside municipal services — an On-Site Sewage Disposal System notification from Nova Scotia Environment, and provincial Transportation approval where work touches a provincially owned road or its right-of-way.
The municipality also states that anybody can apply for a building permit, and that permits expire two years from issue. A building permit is always required for a new residential structure — the exemption is about who may design, not whether you need a permit.
Where a designer still earns their fee
Legal permission is not the same as a good idea. Complex sites, coastal exposure, barrier-free design and anything structural beyond prescriptive code tables all reward professional involvement. The statute tells you what you may do without an architect; it doesn't tell you what you should do. That judgement is yours — now with the actual rule in front of you.
