What restrictions apply for building retaining walls?
Retaining walls require a building permit if they are going to be more than 0.6 metres in height, either as one wall, or in combination with other walls unless they are suitably spaced. Retaining walls over four feet in height are not permitted on residentially zoned properties except those constructed as a condition of subdivision approval or those approved by a building inspector when specific conditions are met. Retaining walls over 1 metre require structural design and review by a professional engineer.
