HOME ADDITIONS TORONTO

More Space.
Same Address.

Second-storey additions, rear extensions, and in-law suites across Toronto and the GTA. Drawings, permits, and construction handled end to end — by one team.

WHAT WE BUILD

Types of Home Additions

Which addition suits your home depends on your lot, your zoning, and your budget. We assess all three before a single drawing is made.

Second Floor Addition in Etobicoke

GO UP

Second Floor Additions

Toronto has thousands of bungalows on lots that cannot expand outward. Adding a storey delivers bedrooms with bathrooms — and the look of a new build.

Rear House Addition Toronto

GO OUT

Side & Rear Extensions

Where bylaw height limits cap how high you can build, extending at the front or rear is the answer — often without gutting the whole house.

Garden & In-Law Suites

The most economical route. Garage conversions and secondary suites add livable square footage with minimal structural conflict.

THE TRANSFORMATION

HOW WE WORK

Our Home Addition Process

Six steps from first conversation to final walkthrough — one team responsible for all of it.

01

Consultation

We start on your kitchen table, not ours. We walk the property, listen to what you want to build, and give you a straight read on what your lot and budget allow — before any commitments.

02

Design & Drawings

Our in-house designers turn the vision into architectural drawings, with revisions until the layout, elevations, and finishes are exactly right. You approve every sheet before it moves forward.

03

Budgeting

A line-item estimate tied to the approved drawings — structure, mechanicals, finishes, allowances. No vague per-square-foot guesses, and no surprises buried in the fine print.

04

Contract & Permits

A fixed-scope contract, then we handle the City: zoning review, permit drawings, and submission. You sign; we deal with the paperwork and the examiners.

05

Construction

One dedicated project manager, a vetted crew, and scheduled updates. The site is kept clean, the neighbours are kept happy, and the schedule is kept honest.

06

Completion & Warranty

A detailed walkthrough, a deficiency list driven to zero, and your Tarion warranty coverage confirmed in writing. Then we hand over the keys.

Home Addition FAQs

Permits, timelines, budgets, and warranties — the questions every homeowner asks before adding on.

Still have a question?
Ask us directly — no obligation.

Yes. Any addition that changes the building footprint or adds floor area requires a building permit from the City of Toronto. ALBO handles the drawings, zoning review, and permit submission as part of the project.

Most additions run 5 to 9 months from permit issuance to completion, depending on scope. Second-storey additions typically take longer than rear extensions due to structural work.

Additions in the GTA generally start around $400 per square foot for finished space, varying with structural complexity, finishes, and site access. We provide a detailed, itemized estimate before any work begins.

Often yes for rear or side extensions, where we can isolate the work zone. Second-storey additions usually require temporary relocation while the roof is open.

ALBO Homes is a Tarion Registered Builder. Coverage requirements vary by project type — we will confirm what applies to your addition during the consultation.
