DELVIN GROUP • ARU Design Toronto

Additional Residential Unit Design Toronto – ARU Permits & Architectural Plans

Professional architectural design and permit support for Additional Residential Units in Toronto and the GTA. We help property owners evaluate, design, and document ARU projects with clarity and technical precision.

Common Challenges We Help Solve

Adding residential capacity to an existing property involves navigating complex site conditions, zoning requirements, and permit processes. Early evaluation and coordinated design help property owners avoid delays and costly revisions.

Unclear Development Potential

Property owners are unsure whether their site can accommodate an Additional Residential Unit or what constraints may apply based on zoning, site coverage, or existing structures.

Inefficient Space Planning

Available space is not optimized for circulation, natural light, privacy, or functional living, resulting in layouts that feel cramped or fail to meet building code requirements.

Incomplete Permit Documentation

Drawings lack the technical detail, site analysis, or consultant coordination needed for municipal review, leading to resubmissions and approval delays.

Fragmented Design and Approval Process

Without a clear roadmap from evaluation through permit submission, property owners face uncertainty about timelines, requirements, and next steps.
About the Service

Additional Residential Unit Design & Permit Support in Toronto and the GTA

Delvin Group provides architectural design and permit coordination for Additional Residential Unit (ARU) projects across Toronto and the Greater Toronto Area. We work with homeowners, property owners, and investors to evaluate existing properties, assess development potential, and create functional, code-informed designs that support residential intensification. Our process begins with a review of the existing property, site conditions, zoning context, and project goals. We analyze available space, access, circulation, natural light, privacy, and applicable planning and building requirements before developing design options. From there, we prepare architectural drawings, coordinate with consultants as needed, and support the permit application process. ARU projects may include secondary suites, garden suites, laneway houses, or residential conversions that add dwelling capacity to an existing property. Each project is site-specific, and feasibility depends on property characteristics, municipal regulations, and design objectives. Delvin Group does not guarantee zoning compliance, permit approval, or project feasibility. Our role is to provide technically sound architectural documentation and coordinated support throughout the design and permitting process.
