What is a Garden Suite?

Garden suites – also called detached suites, accessory dwelling units (ADUs), coach houses, laneway homes, carriage homes, granny flats or backyard cottages – are small, independent homes built on the same lot as an existing single‑family home.

The Province of British Columbia describes garden suites as detached accessory dwelling units that are part of a broader category called small‑scale, multi‑unit housing (SSMUH) ↗. They are ground‑oriented and usually tucked into a back or side yard, providing an independent living space while remaining close to the main house. In most cases, a garden suite can only contain one dwelling unit and is intended for long‑term living – not for short‑term rentals like AirBnB (but this depends on the municipality). Common sizes run between 400–1,000 sqft.

Benefits of building a Garden Suite

Multi‑generational living & aging in place

A detached garden suite offers a private home for aging parents, adult children or caregivers. Seniors can downsize and “age in place” while staying close to loved ones.

Rental income

Long‑term rentals help homeowners offset mortgages or generate steady income.

Work‑from‑home flexibility

Many clients use garden suites as offices, art studios or guest cottages.

Property value

Adding a legally permitted suite can boost resale value and make a property more attractive in a tight housing market.

Sustainability & efficient design

Modern codes require garden suites to meet Step 3 of the BC Energy Step Code for energy efficiency, making them comfortable and cost‑effective to run.

Recent bylaw changes create new rental opportunities for Victoria homeowners like you

British Columbia’s Housing Statutes (Residential Development) Amendment Act, 2023 (Bill 44) introduced a sweeping Small‑Scale, Multi‑Unit Housing (SSMUH) mandate. The provincial government requires local governments to allow secondary suites and/or accessory dwelling units (eg. detached garden suites) on residential lots province‑wide and to update zoning bylaws by June 30, 2024. The legislation also requires the allowance of:

  • 3–4 units on single‑family or duplex lots within urban containment areas or municipalities over 5 000 people
  • Up to 6 units on lots near frequent bus service

In July 2024 the District of Saanich rezoned approximately 27,000 lots to comply with SSMUH. The amended zoning now permits both a secondary suite and a detached garden suite on eligible RS or RD‑zoned lots inside the Urban Containment Boundary, and also allows secondary suites on eligible lots outside the boundary.

The City of Victoria on the other hand already allows a mix of housing types under its “Missing Middle” and house‑conversion programs, so the provincial SSMUH rules apply only to a handful of “restricted” zones. Instead of doing a quick, stand‑alone amendment, Victoria opted to incorporate the new density rules into a comprehensive Official Community Plan (OCP) update and a “zoning modernisation” project. As of October 2nd 2025, the new OCP/bylaws have been signed off by council ↗. This means that City of Victoria properties will be allowed to have both a detached garden suite and an in-home secondary suite, which has historically been prohibited, so this represents a significant liberalization and opportunity for homeowners to generate more rental income.

Why work with a Licensed Builder?

British Columbia’s Homeowner Protection Act requires that anyone who “engages in, arranges for or manages… the construction of a new home” must be a licensed residential builder and arrange home warranty insurance ↗. Even in areas where building permits aren’t required, construction of a new home (including a garden suite) must be carried out by a licensed builder ↗, unless the homeowner qualifies as an owner builder by passing the BC Housing Owner Builder Exam ↗. Partnering with a licensed contractor ensures your project complies with the BC Building Code, meets the BC Energy Step Code, and qualifies for a new‑home warranty.

Constructo Group’s design-build service for Garden Suites

Constructo Group is a Licensed Residential Builder (#55931) and General Contractor based in Victoria. We provide one point of contact from design through construction, giving you full accountability and peace of mind. Our role is to bridge the gap between design vision and build reality—blending creativity with practical planning to deliver beautiful, durable garden suites.

Every municipality has its own bylaws, policies and design considerations. During our initial site visit, we:

  • Review your property’s zoning, lot size and covenants against municipal eligibility criteria (e.g., RS/RD zones, minimum lot area and width)
  • Discuss your goals – whether you’re housing family, creating a rental, adding a home office or planning for multi‑generational living
  • Identify servicing requirements (water, sewer, storm) and parking needs. Many municipalities require at least one on‑site parking space and recommend provision for EV charging.
  • Explain building and permit steps so you know what to expect.

 

We collaborate with trusted local designers, contributing a builder’s perspective to make sure your plans are feasible, cost-effective, and ready for approvals. Our team assists with:

  • Design consultation – Reviewing layouts, elevations and 3-D models to ensure they align with both municipal guidelines and your budget, while considering natural light, privacy, accessibility and energy efficiency.
  • Permit drawings & approvals – Preparing all documents needed for development permits, building permits and tree permits, and coordinating with municipal planners and engineers.
  • Energy efficiency & sustainability – Ensuring the design meets the BC Energy Step Code (currently Step 3 for small dwellings). We recommend high‑performance building envelopes, airtight construction, heat‑pump heating/cooling and EV‑ready electrical service.

 

As licensed builders, we manage every aspect of construction:

  • Site preparation – Surveying, excavation and servicing (water, sewer, storm and electrical). Our relationships with local engineers and inspectors expedite approvals.
  • Quality craftsmanship – Our skilled trades build to the highest standards using durable, low‑maintenance materials. We’re small enough to handle much of the work in‑house, but experienced enough to coordinate specialists when needed.
  • Project management – We schedule and supervise all trades, handle inspections, and keep you updated. This integrated approach controls costs and accelerates completion.
  • Warranty & handover – Upon completion, we provide a new‑home warranty and walk you through operation of the suite’s systems. We also offer maintenance packages to protect your investment.

 

After you move in or rent out the suite, we remain available. We’ll address any warranty issues and can help you navigate changes to municipal bylaws.

Frequently asked questions about building a detached garden suite in Victoria BC

Timeframes vary depending on municipal review timelines, but typically:

  1. Property assessment & preliminary design – 2–4 weeks.
  2. Development & building permit approval – 3–6 months (depending on municipality and complexity).
  3. Construction – 3–6 months. Projects that involve complex foundations or service upgrades may take longer.

Yes, unless you qualify as an owner builder. The Homeowner Protection Act requires anyone who constructs or manages a new home (including a new garden suite) to be a licensed residential builder and to arrange home‑warranty insurance. If you wish to act as your own builder, you must pass the BC Housing Owner Builder Exam. Partnering with Constructo Group eliminates this hurdle, as we are licensed and insured.

Saanich requires RS or RD‑zoned lots within the Urban Containment Boundary to have a minimum area of 400 m² and a minimum width of 12 m. Other municipalities have similar requirements; we confirm your lot’s eligibility during our initial assessment/consultation.

No. Both Victoria and Saanich restrict garden suites to long‑term residential use; short‑term rentals or "Airbnb" uses are not permitted (at the time of writing).

It depends, but the answer is increasingly becoming "yes". In Saanich, as of June 30 2024, RS and RD‑zoned properties may have both a secondary suite and a garden suite. In Victoria, properties with an existing secondary suite or duplex have historically not been eligible for a garden suite, but this is expected to change once council adopts the new OCP and zoning amendments (expected later in 2025).
