L-104.3 Local rules
Renovating in Richmond Hill: what to know
Neighbourhoods and homes
We work across Richmond Hill, from the older streets around Yonge Street, Mill Pond and Richvale to Bayview Hill, Westbrook, Jefferson and the Oak Ridges and Lake Wilcox area on the moraine. Many homes here are larger family houses from the 1980s onward, and their original bathrooms and kitchens are often the first rooms to go. Older lots closer to the core tend to have mature trees, which matter if you plan to build out.
Permits
- Renovations, additions, interior alterations, plumbing and HVAC changes need a building permit. Painting, landscaping, re-shingling (except clay tile) and minor repairs do not. Applications are made online through the city’s permit portal; the city’s service charter targets 10 business days for house permits after a 2-day completeness check. Source: City of Richmond Hill: Building Permits
- Additions over 400 sq ft: an addition with a footprint greater than 400 sq ft needs a site alteration permit before you apply for the building permit, with a grading and servicing plan prepared by a professional engineer or Ontario land surveyor, and refundable deposits. Sources: City of Richmond Hill: Residential Permits · Site Alteration Permits
- Trees: removing or injuring a tree on private property with a trunk diameter of 15 cm or more (measured at breast height) needs a permit, and work inside a tree’s protection zone counts as injury. Source: City of Richmond Hill: Trees on Private Property
- Decks: a permit is needed if the deck is attached to the house, more than 600 mm (2 ft) above average grade, or larger than 10 m² (108 sq ft). Decks can’t be attached to brick veneer, and zoning setbacks apply. Source: City of Richmond Hill: Deck Permit checklist (PDF)
- Additional residential units: allowed in zones that permit detached, semi-detached and certain townhouses, up to four units on a lot in total, with building permits. The lot must be on municipal water and sewer. Source: City of Richmond Hill: Additional Residential Unit
- Heritage: alterations that affect the heritage attributes of a designated property, or a property in the Gormley Heritage Conservation District, need the city’s written consent (a heritage permit) before work starts. Owners of listed properties must notify the city before demolishing, and the city has 60 days to respond. Source: City of Richmond Hill: Cultural Heritage Planning
