Q: How much is Hamilton's ADU grant?

Hamilton's ADU and Multi-Plex Housing Incentive Program grant covers 70% of eligible costs up to $40,000 per eligible unit, with a first advance of 20% (max $8,000). A building permit must be issued before a grant decision is made, and the property must fall within the program's Community Improvement Project Area.

Q: Do older Hamilton homes have different permit requirements?

The Ontario Building Code applies different provisions based on the age of the building - fire separation and structural details for a 1920s brick home differ from a 1990s build. Drawings should account for the home's vintage from the start.

Ontario Design Studio provides BCIN-certified building permit drawings for projects in the City of Hamilton. Our team prepares OBC-compliant drawings for residential and commercial permits across Hamilton's diverse neighbourhoods.

💰 Hamilton's ADU Grant: Up to $40,000 Per Unit

Through the City's ADU and Multi-Plex Housing Incentive Program, eligible homeowners can receive a grant covering 70% of eligible costs, up to $40,000 per eligible unit - with a first advance of 20% (up to $8,000) to help fund early work.

Your property must be within the Housing for Hamilton Community Improvement Project Area (most of the city, with limited exceptions)
A building permit must be issued before any grant decision is made - which makes getting your drawings right the critical first step

We prepare the complete permit drawing package the grant application depends on, and our documentation is built to satisfy both the Building Division and the incentive program's file requirements.

How the Hamilton Building Permit Process Works

Hamilton runs a dedicated ADU review team for existing single-family homes - covering up to two units inside the house plus one detached unit. A few Hamilton-specific realities we design around:

House age matters: different Ontario Building Code provisions apply depending on when your home was built - critical for Hamilton's large stock of pre-war and century homes
Water service sizing: adding units can require upsizing the water service line on the private and/or public side, depending on total fixture counts
Escarpment and grading: Mountain-brow and lower-city properties can carry different grading and drainage requirements

Don't leave $40,000 on the table.
