A basement apartment with its own compact kitchen, a large egress window in a window well under a smoke alarm, and its own entrance door.

What’s included

What a second
unit takes.

One part after another, a finished basement is made into a second dwelling.

  • A basement apartment’s own walkout entrance at the back of a brick house: a sunken limestone patio, steps down and a glazed door under a cedar canopy.

    A separate entrance

    A door and stair of its own, placed where the zoning allows an entrance, so nobody walks through the house above.

  • A basement apartment’s own bathroom, with a tub and shower behind a glass panel and a compact vanity under a high window.

    Its own kitchen and bathroom

    Both plumbing and electrical serve the unit alone, and the drains and supply lines run clear of the floor above.

  • A solid fire-rated door with a closer between the apartment and the house, and a smoke and carbon monoxide alarm on the ceiling.

    Fire separation, smoke alarms and egress windows

    A rated separation between the two units, interconnected smoke alarms, and bedroom windows large enough to leave through.

  • A basement apartment framed, insulated and closed in overhead with fire-rated drywall, a new egress window set in the foundation wall, ready for inspection.

    Permits and inspections for a legal unit

    Zoning must allow the lot. A building permit, inspections at stages and a separate electrical permit are needed.

How it runs

One bay of it,
stage by stage.

Five stages run in the same order on a room or a whole house, and one builder is accountable for each.

  1. 01

    Permits

    Zoning gets looked at ahead of the building permit, since not every lot qualifies.

  2. 02

    Structure

    Framing is where the walls and ceiling that sit between the units become fire separations.

  3. 03

    Trades

    The house above stays separate: supply lines, drains and shut-off valves are run, then the unit’s wiring.

  4. 04

    Finishes

    Alarm wiring runs through both units, and the bathroom, kitchen and floors come next.

  5. 05

    Handover

    Move-in comes after the final inspection, when the permit is closed.

Why Hanna Homes

Why one builder
for all of it.

What a second unit asks of a builder, settled first.

The schedule is built around the final inspection. A unit can’t be lived in until it passes, and that puts a tenant’s date second.

The unit gets its own fire separation, its own plumbing and its own electrical permit, as a dwelling does, instead of a kitchen added to a finished basement.

Planning and inspection both treat interconnected smoke alarms and the fire separation as a pair, so neither becomes an afterthought.

A street-facing elevation may have no more than one exterior entrance, which puts the separate door ahead of the stair and grading.

Client reviews

Their house,
their words.

01Basement apartments

We turned the basement into a unit for my mother-in-law. She has her own entrance and her own kitchen, and we still get Sunday dinners. The paperwork I was dreading turned out to be the part I thought about least.

Daniel K.Kitchener
02Whole home

We put off the whole house for years because we couldn’t picture living through it. Akram walked us through every stage before it started, and each week went the way he said it would.

Laura M.Oakville
03Kitchens

The crew covered the floors and cleaned up at the end of every day, which mattered with two kids at home. The new kitchen is the room everyone ends up in now. Worth every week of takeout.

Sanjay P.Burlington
04Custom homes

Building a new house was the biggest decision we’ve ever made, and it never felt rushed. We walked the site most Saturdays and always knew exactly where things stood.

Michelle R.Ancaster
05Additions

We needed more room but didn’t want to leave the street. The second storey went on over the summer, and from the sidewalk you’d think the house was always built that way.

Greg H.Burlington
06Bathrooms

One bathroom is a small job for a builder, but they treated it like the whole house. The tile lines up, the door finally closes properly, and they finished the week they said they would.

Ana T.Cambridge
07Knockdown & rebuild

Our old bungalow wasn’t worth saving, so we took it down and built new on the same lot. They kept the neighbours in the loop from demolition to the final walk-through. We love coming home to it.

Priya S.Oakville
08Basements

The basement used to be storage and a furnace. Now it’s a family room the kids actually want to be in. A clear quote, no surprises, and the site was swept every night.

Kevin L.Ancaster
09Whole home

We bought an older house knowing it needed everything. Akram was straight with us from the first visit about what was worth keeping. Every room is new to us now, and it still feels like the house we fell for.

Third builder we spoke to, and the only one who returned every call. When we changed our minds about the island halfway through, they made it work without any drama.

Common questions

Common questions
in Hamilton.

The water line can move it first. Hamilton requires adequate servicing to be approved before the building permit is issued, and a larger water service or meter may be needed. After that come the entrance and any excavation, the kitchen and bathroom, and the fire separation. A price needs those answers first.

The servicing approval has to come before the permit, so it is the first wait. A heritage-designated house cannot be permitted until its Heritage Permit is approved, which adds another. Then the entrance, framing, trades, fire separation and the inspections at set stages. No duration is quoted yet.

A building permit, after servicing approval. New or relocated plumbing is permit work on Hamilton's list, and a designated property also needs a Heritage Permit first. Even a unit that meets the zoning rules must still meet the Ontario Building Code and Fire Code. Hanna Homes handles the permit file and books the inspections.

Two things together: zoning that allows the unit, and construction that meets the Building Code and Fire Code. On the build side that means a private way in, a kitchen and bath for the unit, a fire separation from the rooms above, smoke alarms wired to each other, and windows or doors big enough to escape through. Hamilton allows one second unit in a single-detached, semi-detached or townhouse dwelling; more than one stays illegal.

No. The City says second units in duplexes and triplexes remain illegal, and so does a second unit beyond the first in a single-detached, semi-detached or townhouse dwelling. Those checks come before design, along with the entrance and the servicing.

People also ask

Before you build,
people in Hamilton ask.

What people in Hamilton search before basement apartments, answered for the town.

  • Yes, in a single-detached, semi-detached or townhouse dwelling, if it meets the zoning, the Building Code and the Fire Code. Duplexes and triplexes cannot have one.

  • Yes. The Building Code expects a way out a person can actually use, which in a basement means an egress window or door, and inspectors check it.

  • The unit is built to the Code and inspected. Its trade-off is the work: servicing approval, a permit, a separate entrance and a fire separation before anyone moves in.

about legal basement apartments in Hamilton.

What changes the work in Hamilton: the rules, the houses and the ground.

Legal basement apartment permits in Hamilton

Hamilton requires an additional dwelling unit to have adequate servicing approved before the building permit is issued, so the water service is looked at first, and a larger service or meter may be needed. The building permit then follows, with inspections at set stages. Meeting the zoning rules is not enough on its own: the unit has to satisfy the Ontario Building Code and Fire Code too. New or relocated plumbing is also permit work on the City's list. A heritage-designated house cannot be permitted until its Heritage Permit has been approved.

Secondary suite in Hamilton: what the job includes

A secondary suite gets a private entrance, reached by a stair down at the side or back of the house, or by a walkout if the grade allows. A full kitchen and a bathroom serve it, and the plumbing, electrical and ventilation behind them are coordinated by the builder. A fire separation divides the suite from the house above, the smoke alarms are interconnected, and egress windows or doors give a way out. The licensed builder is about 15 minutes away in Burlington and coordinates the trades and the inspections.

Basement second unit in Hamilton: cost and timing

What moves the cost is the entrance and any excavation outside, the kitchen and bathroom, the fire separation, and the approvals. In Hamilton the servicing step adds a line the others do not: a larger water service or meter, if the City asks for one. Time starts with that approval and the permit behind it. The build then runs in order, entrance and framing, trades, separation and alarms, then inspection at set stages. A unit is legal to rent only once those are passed.
