• Secondary Suite Development

Secondary Suite Development

Secondary Suite 

A self-contained dwelling unit within the main residence that has separate living, sleeping, cooking and bathroom facilities.  These are commonly referred to as basement suites or in-law suites.  A permit process exists if you are planning on developing a secondary suite. Please contact Planning Services at 403-995-2760 or planning@okotoks.ca to determine whether your house is zoned correctly. A development permit and a building permit must be obtained prior to construction of a secondary suite.

It’s important to ensure suite development respects the nature and density of the neighbourhood and doesn’t result in the creation of duplexes where only secondary, studio (e.g. ‘bachelor’) suites are intended.   Regulations exist to minimize impacts of the suite on other, surrounding properties and to provide for the development of safe living spaces.  It’s easier, less expensive and less stressful to develop the suite with the required Development and Safety Code Permits, in compliance with land use and safety codes requirements.

Please refer to Secondary Suite Development Guidelines.

Existing Suites

There are many benefits involved in making an existing suite legal.  The building permit application process required to legalize a suite ensures that the Alberta Building Code is met and all safety issues comply.

Consequences Involved When No Permit Obtained

  • Enforcement action or stop work order issued by the Town of Okotoks inspector

  • Fines for building without a permit

  • Undo and redo work that has been completed potentially increasing your budget significantly

  • Future legal and financial issues when you sell your property or make an insurance claim

    Note:  It is the responsibility of the applicant to ensure that the work being carried out conforms to any restrictive covenants, caveats or other restrictions that are registered at land titles.

  • Studio Suites can be considered in most residential districts in Okotoks.
  • Some of the important standards to be aware of include:
    • One extra parking space is required on the lot in addition to the minimum spaces required for the house;
    • Parking for the suite must be independent of other parking spaces, e.g. cannot be tandem (end to end) with a space required for the house;
    • Suite size is not to exceed the lesser of 40% of the floor area of the dwelling or 75 square meters;
  • A Development Permit is required and the process can be expected to take up to 6-8 weeks.
  • For more information on Development Permit requirements, visit www.okotoks.ca and select Town Services – Planning & Development – Planning – Development Permits – Developing a Studio Suite/Secondary Residential Suite. http://www.okotoks.ca/town-services/planning-development/planning/development-permits
  • Safety Codes permits are required (Building, Plumbing, Electrical, Gas) and the suite must meet Alberta Building Code requirements for minimum safety standards.  The safety codes permits will be issued only after a valid Development Permit has been approved, and may take an additional 2-4 weeks.

Step One: Development Permit Application

Please review the Studio Suite Information Sheet and the Development Permit Requirement Checklist under Publications & Forms.

A Development Permit is required before safety codes permits may be issued.  To apply, submit a complete application form with the fee of $250 and the supporting documentation outlined on page 1 and in the studio suite section of the checklist.

Planning Services will post a notice on the property and notify adjacent property owners of the application at least 21 days before a decision is made.  The application will be referred to the Municipal Planning Commission for a decision at one of their monthly meetings and a Notice of Decision will be issued to the applicant the following day.  If approved, the approval is advertised in the following week’s edition of the Western Wheel and anyone who believes they are affected has 14 days to appeal.  The Development Permit is issued 15 days after advertising provided no appeals are received, and any conditions of approval that are required to be met before issuance, as outlined in the Notice of Decision, have been met by the applicant.
