Developer Permits

If you are a Production Builder and wish to have your model plans certified before applying for building permits to construct the houses, please review and complete the following:

• Complete a Certified Model Plan (C.M.P.) for each model. 
• The models need to be reviewed and certified by the City before applying for building permits.
• A certified model is not a building permit. You must apply for a permit to construct on each lot the certified model will be built.
• The Model Certification does not include a review of Applicable Law. Applicant is responsible to ensure each permit application for each lot complies with all applicable laws.
• C.M.P. reviews for multiple models may take 2 to 3 months. For a smoother building permit application process, you should submit your models for certification before a subdivision or Site Plan Agreement is registered.

To construct a new house in a subdivision using a Certified Model Plan, the Certified Model Plans must be approved by the City and your proposed site must be registered.

NOTE: if the C.M.P. certification is not finalized before submitting permits, the applications will be accepted with an incomplete status.

Your new construction must comply with Oshawa's Zoning By-Law. For information on how your property is zoned, view our Zoning page. 

Schedule D Conditions

All Subdivision Agreements have Schedule D conditions that must be met before building permits will be issued. Before applying for any building permits, review the conditions in the Subdivision Agreement to ensure there are no outstanding Schedule D conditions.

Fire Access Information to Consider

Fire Prevention reviews and approvals any private roadways for residential or commercial developments provided with a single access point that fall outside the prescriptive requirements of the Ontario Building Code as amended.

The requirements of these private roads are:

• All lengths of roadway are to be measured along the centerline of the roadway.

• The roadway shall be a minimum 6m wide, with a minimum 12m centerline-turning radius and be at least 3m from any portion of a building.

• Maximum 90m long access street or “throat” entering into the property from a municipal road (measured from the centerline of the municipal roadway lane closest to the subject property and measured to the curb at which an intersection is created).  

• The maximum distance from centerline of municipal road to the furthest point of private roadway shall not exceed 250m. This dimension shall be measured to the centerline of the most remote point in the roadway.

• The minimum distance from building to building across private roadway shall not be less than 12m.

• The cumulative length of all private roadways within the subject development area shall not exceed 750m.

• If the private roadway is connected to a municipal road that also has a single access point of access (ie cul-de-sac), all measurements shall be calculated from the single access point of the municipal road.  Therefore, the distance from the single point of access for the private roadway to single point of access for the municipal road, shall be added to all private roadway lengths.
• Any proposed private roadway designs not meeting the above requirements must include a rationale prepared by a Professional Engineer or Architect.  These proposed designs must be approved by the Fire Chief and/or Deputy Fire Chief in consultation with the Chief Fire Prevention Officer.

For information regarding Secondary or Emergency Access, please see City of Oshawa Engineering Design Manual, section 3.16 Secondary or Emergency Access (page 52).

Waste Removal requirements

Eligibility for municipal waste collection services is contingent upon adherence to specific municipal design standards and compliance with the Waste Collection By-law.

Please contact Operations Services staff during the design stage to proactively address concerns with the site that would not allow for municipal waste collection and to incorporate any changes ahead of construction.

You site will require inspection prior to assumption of service in order to determine if the site is eligible for municipal collection. 

If your site does not conform to the City's standards for municipal waste collection services, the property owner/manager will be required to retain private waste collection services at their expense.

For further information, guidance, or to submit your plans for review, please reach out to Service Oshawa.

We are here to assist you in meeting the necessary requirements to ensure a smooth and compliant development process.

For more information visit Multi-Residential Services.

To speak to Operations Services Staff to review your plans, please contact Service Oshawa.
