Permit Submission Design Services in Ontario

RN Engineering provides HVAC, plumbing & drainage, and fire protection design services for permit submission projects across Ontario, including residential, commercial, industrial, mixed-use, tenant fit-up, and change-of-use projects..

We support residential, commercial, industrial, and mixed-use projects where clear, coordinated engineering design is required for building permit submission, construction coordination, or project approval. Our team prepares professional design packages for a wide range of project types, including custom homes, single-family homes, restaurants, offices, retail units, medical and dental clinics, tenant fit-ups, change-of-use projects, and industrial spaces.

Whether your project is small or complex, RN Engineering can help review the mechanical design requirements, prepare the required drawings, and support the submission process with practical and code-conscious design.

Mechanical Design Support for Permit Submission

Many projects in Ontario require mechanical design input before construction can begin. Depending on the scope of work, this may include heating, cooling, ventilation, exhaust, make-up air, plumbing, sanitary drainage, storm drainage, sprinkler coordination, or fire protection review.

RN Engineering helps owners, architects, contractors, designers, and builders prepare coordinated mechanical design documents that support the permit submission process and help reduce delays during review.

Our design work is prepared using AutoCAD and Revit, allowing us to provide clear, organized, and coordinated drawings for both residential and commercial projects
