Why Ottawa homeowners choose Dream Touch Renovations for home additions

Dream Touch Renovations has been the home addition contractor Ottawa families have trusted since 2005, with more than 500 completed projects across Barrhaven, Kanata, Orleans, Westboro, Nepean, Manotick, and every neighbourhood in between. As a Licensed Ontario General Contractor, fully insured for new-build components, Dream Touch delivers fixed-price contracts and a 98% on-time rate, backed by written delivery dates in every agreement. For homeowners looking for an addition builder they can rely on, that track record is the foundation we build on.

We build the five categories of Ottawa home additions homeowners most commonly need: second storey addition Ottawa projects that transform bungalows into full two-storey homes; rear addition Ottawa extensions that expand kitchens, family rooms, and primary suites into the backyard; side addition Ottawa projects for narrow urban lots in the Glebe, Westboro, and Hintonburg; bump out addition Ottawa work for targeted four-to-eight-foot expansions of existing rooms; and dormer addition Ottawa solutions for 1.5-storey homes that need attic bedrooms without expanding the footprint. Every home extension Ottawa we build is designed in-house with full architectural plans and constructed by our own crew

What sets Dream Touch apart from every other Ottawa builder is deep local expertise. We know which lots qualify for which additions, where lot-coverage limits bite, where setback minimums apply, and how to navigate the Committee of Adjustment variance process. We know Ontario Building Code compliance, and we work daily with the City of Ottawa's building permit system. That expertise is what makes our free 48-hour lot feasibility review and our fixed-price contract model possible. Explore our Bill 23 Guidance page for the new multi-unit provisions, or our Financing options to see how Ottawa homeowners fund their additions.

The Ottawa math

Why more Ottawa homeowners are building additions instead of moving

Home addition Ottawa after second-storey construction Before After
Every type of Ottawa home addition

Find the right addition for your home and lot.

The right Ottawa addition depends on four factors: lot shape, existing home structure, budget, and the new space you need. Dream Touch builds all six common Ottawa addition types. Second-storey additions dominate bungalow neighbourhoods like Alta Vista, Carlington, and Bells Corners. Rear additions are most common in suburban Ottawa including Barrhaven, Kanata, Orleans, Findlay Creek, Stittsville. Side additions are the standard in older central Ottawa especially the Glebe, Westboro, Hintonburg, Centretown, Sandy Hill, New Edinburgh. Every Dream Touch house addition Ottawa project starts with a free feasibility review to confirm which type your lot supports.

Second Storey Addition

Add a full second floor to a bungalow or single-storey home. Ottawa's highest-impact addition typically, doubles living space and adds 20–30% to home value. Most common in Alta Vista, Carlington, Riverside, and Bells Corners bungalow neighbourhoods.

Largest scope · full structure Timeline: 16–20 weeks Additional Footprint: 800 - 1,000 Sq Ft Most common in Alta Vista · Bells Corners · Riverside

Rear Addition Ottawa

Extending the back of your home for a new kitchen, family room, or primary suite. Ottawa's most popular addition type, ideal when your backyard has room to spare. Common in Barrhaven, Kanata, Orleans, and Manotick.

Mid scope · new foundation Timeline: 12–14 weeks Additional Footprint: 350 - 475 Sq Ft Most common in Barrhaven · Kanata · Orleans · Manotick

Side Addition Ottawa

Extending sideways when rear yard is shallow or front is restricted. Common in older central Ottawa neighbourhoods with narrow lots like the Glebe, Westboro, Hintonburg, Centretown, Sandy Hill, New Edinburgh, and Rockcliffe.

Mid scope · narrow-lot build Timeline: 11–14 weeks Additional Footprint: 300 - 425 Sq Ft Most common in Glebe · Westboro · Hintonburg · Sandy Hill

Bump-Out Addition Ottawa

A small, targeted extension, typically 4–8 feet, to expand a kitchen, bathroom, or bedroom without a full addition. Ottawa's fastest and most affordable addition option. Popular in Nepean, Vanier, Gloucester, and Overbrook.

Smaller scope · targeted extension Timeline: 8–10 weeks Additional Footprint: 160 - 270 Sq Ft Most common in Nepean · Vanier · Gloucester · Overbrook

Garage Conversion Ottawa

Convert your existing garage into a bedroom, home office, gym, or in-law suite. Zero foundation work, dramatic cost savings, fastest timeline. Popular across Ottawa, especially where lot coverage limits prevent expansion.

Smallest scope · no foundation Timeline: 5–7 weeks Additional Footprint: 400 - 500 Sq Ft Popular across Kanata · Barrhaven · Orleans · Nepean

Dormer Addition Ottawa

Add usable space within your existing attic footprint by raising a dormer. Perfect for Ottawa's many 1.5-storey homes in Centretown, Sandy Hill, Hintonburg, and Westboro. Create extra bedrooms without expanding the footprint.

Smaller scope · within roofline Timeline: 8–12 weeks Additional Footprint: 400 - 560 Sq Ft Common in Centretown · Sandy Hill · Hintonburg · Westboro

Case study · Second-storey addition

A bungalow becomes two full storeys.

Illustrative example
Ottawa bungalow after gaining a full second storey, representative of Dream Touch Renovations second-storey additions Before After

An illustrative before-and-after of a typical bungalow-to-two-storey conversion — representative of the second-storey additions we design, permit, and build, not a specific client project.

Second-storey additions are how many Ottawa families double their floor area without leaving the neighbourhood they love. This walkthrough is a representative example of how Dream Touch takes a single-storey home to two full storeys — same lot, same address — roughly the path every second-storey project follows.

Typical scope
  • Full second storey built over the existing footprint
  • New primary suite plus additional bedrooms upstairs
  • Existing roof removed and rebuilt to the new rooflines
  • Foundation and framing reviewed and sized by a structural engineer
  • Whole-home electrical, plumbing, and HVAC extended and brought up to current code
  • Siding, windows, and trim blended so old and new read as one house
How a second storey gets built
  • Feasibility & design
    Free 48-hour lot feasibility to confirm height and coverage, then in-house architectural drawings and a SketchUp 3D model approved before any pricing.
  • Permits & structural engineering
    Building permit filed through MyServiceOttawa with structural engineering for the new floor loads, plus a Committee of Adjustment minor variance if height or coverage requires one.
  • Roof removal & framing
    The existing roof comes off and the new second-floor structure is framed to the engineered drawings and the Ontario Building Code, with the home weather-protected throughout.
  • Systems & finishes
    Electrical, plumbing, and HVAC are run to the new floor, then insulation and interior and exterior finishes are completed and blended to the existing home.
  • Inspections & handover
    Municipal inspections are passed, the project manager walks the finished floor with you, and the addition carries a 1-year workmanship warranty.
Zoning · By-Law 2008-250 · Lot Coverage · Setbacks

Can you build a home addition on your Ottawa property?

Not every Ottawa lot is suitable for every addition type. Before any home addition Ottawa project begins, Dream Touch's free feasibility review confirms what you can build before you spend a dollar on design.

Ottawa's zoning by-law 2008-250 controls every residential addition in the city. Most Ottawa lots fall into one of four residential zones: R1 (detached), R2 (detached + duplex), R3 (townhomes + low-rise), or R4 (multi-unit). Each has distinct rules for maximum lot coverage, setbacks from property lines, building height, and permitted uses. The good news: most Ottawa suburban lots in Barrhaven, Kanata, Orleans, Nepean, Stittsville, Findlay Creek, and Riverside South easily qualify for a full home addition under current zoning. Older central neighbourhoods like the Glebe, Westboro, Hintonburg, Centretown, and Sandy Hill often need a minor variance, which Dream Touch handles.

Dream Touch's feasibility review checks five factors on every Ottawa property: (1) lot coverage percentage versus the zone's maximum, typically 35% for R1 and higher for other zones; (2) setback requirements from front, side, and rear lot lines, typically 6m front, 1.2m side, and 7.5m rear; (3) height restrictions, typically 11m maximum for R1/R2; (4) servicing capacity, confirming municipal water and sewer can support added fixtures; (5) parking requirements, ensuring the required minimum off-street spaces are retained. If any factor fails, we identify the need for a Committee of Adjustment minor variance at the feasibility stage, before you commit to design.

Ottawa's Bill 23 (More Homes Built Faster Act) provisions now allow up to three residential units on most Ottawa lots. That means you can combine a home addition with a legal secondary dwelling unit, like adding a second-storey for your family while converting the basement into a registered rental suite, or building a rear addition plus a coach home in the backyard. For the right Ottawa property, this strategy can generate ongoing monthly rental income on top of the addition's home-value lift. Explore our Coach Homes page for backyard options, or Bill 23 Guidance for the legal framework.

Return on Investment

What's the ROI of a home addition in Ottawa?

Home addition Ottawa ROI depends on two factors Ottawa appraisers always assess: net added square footage and material/finish quality. The table below shows how each addition type tends to recover its investment in resale value, expressed as a percentage so you can compare types before pricing your own project.

Home addition Ottawa pricing is driven by addition type and scope, square footage, finish and material selections, structural and foundation complexity, mechanical and electrical changes, permit requirements, and site conditions. Compact work like bump-outs and garage conversions sits at the lower end; full rear or side additions are mid-scope; second-storey additions are the largest. Every Dream Touch home addition Ottawa project is a written, fixed-price contract signed before permits are pulled, with a detailed itemized breakdown and no surprises.
Expect 8–16 weeks of active construction after permits are issued, plus 4–10 weeks for design and permit processing. Full project timelines from first consultation to handover run 4–7 months. Dream Touch maintains a strong on-time track record across two decades of Ottawa projects, with written delivery dates in every contract.
Yes. Every home addition in Ottawa requires a City of Ottawa building permit, plus trade permits for electrical, plumbing, and HVAC. Structural engineering stamps are required for anything modifying the building envelope. Some additions also need a minor variance requiring a Committee of Adjustment hearing. Dream Touch manages every permit and approval end-to-end.
Most Ottawa bungalows can accommodate a second storey, but it depends on foundation capacity, zoning height restrictions, and lot coverage limits. Dream Touch's 48-hour feasibility review confirms whether your specific bungalow is a candidate, including any foundation reinforcement required. Alta Vista, Riverside, and Bells Corners see the most second-storey addition activity in Ottawa.
For most rear, side, bump-out, and garage conversion additions, yes. Dream Touch seals the construction area from the existing home so daily life continues. For full second-storey additions, a 2–4 week period of temporary housing is typically needed during roof removal and re-sheathing. We coordinate temporary housing through trusted Ottawa partners if required.
Yes. MPAC (the Municipal Property Assessment Corporation) reassesses your property after permits are closed, and your annual property tax rises in proportion to the added assessed value. The increase is typically a small fraction of the project each year, and still well below the land-transfer tax and realtor commission you would pay to sell and buy a larger Ottawa home.
Yes. Ottawa's Bill 23 (More Homes Built Faster Act) and By-Law 2008-250 now allow up to three residential units on most Ottawa lots, including a primary home, an in-law or rental suite, and a coach home. Dream Touch builds legal secondary suites to full City of Ottawa compliance, registered as secondary dwelling units, with separate entrance, fire-rated separation, and code-compliant ceiling heights. See our Bill 23 Guidance page for details.
Many Ottawa additions require a minor variance, typically for lot coverage, setback, or height. Dream Touch's permits team prepares the variance application, represents you at the Committee of Adjustment hearing, and manages any conditions imposed. We identify the need for variance at the feasibility stage, before you commit to design work.
Ottawa home addition ROI varies by type: bump-outs and second-storey additions typically return 20–53% of their cost in home value; rear and side additions return 14–38%; and in-law suite additions add rental income on top of the value lift. Dream Touch runs project-specific ROI analysis for every feasibility review, using 2025 CMHC and Ottawa Real Estate Board comparable data.
Most Ottawa homeowners finance additions through one of four options: a Home Equity Line of Credit (HELOC) against existing equity, a construction-to-permanent mortgage, a refinance of the existing mortgage, or a renovation loan. Dream Touch partners with three trusted Ottawa mortgage brokers who specialize in renovation financing. See our Financing page for details.
