Secondary Suite Zoning Requirements

Share on Facebook Share on Twitter Share on Linkedin Email this link

Since 2012, secondary suites have been permitted in all but a few single detached residential zones, as long as they meet certain conditions. We regularly review these conditions to make sure they are working for the community.

There are three secondary suite requirements currently under review:

1. Removing the secondary suite requirement that all required parking spaces be free and clear of each other.

Homes with secondary suites must have two parking spaces for the occupants of the home and one parking space for the secondary suite tenant. Currently, all three parking spaces must have their own designated spot and tandem parking (a car parked right in front of another) is not allowed. All required parking must be on-site (street parking does not count), so a property with a suite needs to fit three parking spaces either side-by-side or far enough apart so that the parking spaces are easily accessible.

This requirement has resulted in wider driveways, complicated parking configurations (see image gallery on the right) and has made it difficult to meet other zoning regulations about permeability and front yard landscaping. In some cases, this requirement prevents owners from being able to have a legal secondary suite.

Should the City remove this current parking requirement, more properties would be eligible for secondary suites, more owners would be able to meet their landscaping requirements, and less yard area would be devoted to parking. Owners and tenants would need to agree among themselves on how to access their parking spaces without inconveniencing others. It is possible that street parking spaces would be used more often.

2. Removing the minimum lot width of 15 m (49 ft) to be eligible for a secondary suite.

Delta requires a minimum lot width of 15 m (49 ft) in order to be eligible for a secondary suite. Most newly subdivided lots and some irregularly shaped lots have lot widths narrower than that and are not able to have a secondary suite.

Over the years, suite parking requirements have changed and the rationale behind the specific
15 m (49 ft) minimum lot width is no longer relevant. As such, the 15 m (49 ft) minimum lot width requirement is being considered for removal.

If this requirement was removed, the City would allow suites on any properly zoned lot that could fit three required parking spaces on the property.

3. Discharging restrictive covenants that prohibit secondary suites on a property (should the zoning regulations change).

Many previously developed properties have a restrictive covenant registered on title that prohibits secondary suites. This type of restrictive covenant typically includes restrictions that mirror secondary suite zoning regulations and does not add any additional restrictions; however, it increases administrative work for City staff and adds cost and delay to applicants.

If Delta were to change the zoning regulations about parking configuration and lot width, we would also consider removing the related registered covenants and allow these properties to have secondary suites.


Adopting the above changes would make it easier for some owners to construct or legalize a secondary suite within their home, while still requiring enough on-site parking. Alternatively, the requirements could remain as they stand today.
