Are there special landscaping restrictions for heritage properties in NB?

Yes, heritage-designated properties in New Brunswick are subject to additional landscaping restrictions that go beyond standard municipal bylaws, and making unauthorized alterations to the grounds of a designated heritage property can result in orders to restore the site to its original condition. The level of restriction depends on whether the property is designated under the provincial Heritage Conservation Act or under a municipal heritage bylaw, and whether the heritage designation specifically includes landscape features.

Provincially designated heritage properties in NB are listed on the Canadian Register of Historic Places and protected under the New Brunswick Heritage Conservation Act. Any alteration to a provincially designated property — including significant landscaping changes — requires approval from the Minister of Tourism, Heritage and Culture (in practice, the Heritage Branch reviews applications). This can include removing mature trees or hedges that are part of the historic character, changing the grade or contour of the property, installing hardscaping like patios or retaining walls visible from public areas, removing historic fencing or stone walls, and altering garden layouts that are considered heritage-defining elements.

Municipally designated heritage properties are protected under local heritage bylaws in cities like Fredericton, Saint John, and Moncton. Fredericton's heritage bylaw is particularly detailed and covers the Heritage Conservation Areas in the downtown and surrounding historic neighbourhoods. Within these areas, exterior alterations visible from a public street — including fencing, walkways, retaining walls, and significant landscape changes — may require a Heritage Officer's review and approval. Saint John's heritage conservation areas, including the historic Uptown and Trinity Royal districts, have similar review requirements for exterior changes.

Common landscaping activities that may require heritage review include removing or significantly pruning mature trees and hedges (especially those visible from the street that contribute to the historic streetscape), installing modern fencing that does not match the historic character of the neighbourhood, adding paving or hardscaping to front yards, changing the grade or drainage patterns of the property, and installing modern elements like concrete driveways, chain link fences, or vinyl siding on outbuildings.

The review process is manageable. Submit a brief application with photos and a description of proposed work to the heritage officer or advisory committee. Decisions typically take 2-6 weeks. The goal is ensuring changes are compatible with the property's historic character, not preventing all changes. Committees often approve plans with minor modifications — for example, suggesting a wood picket fence instead of vinyl, or recommending historically appropriate native species.

If you own or are purchasing a heritage property in NB, request a copy of the heritage designation documents, which will specify exactly which features are protected. Some designations cover only the building itself, while others explicitly include landscape features like gardens, pathways, stone walls, and mature tree canopy. A landscape architect experienced in heritage properties ($100-250 for an initial consultation) can develop a plan that respects the heritage character while meeting your practical needs. NB also offers heritage property tax incentives and grants to help offset maintenance costs.
