Whitby Housing Stock & History
Whitby's housing spans over 150 years. Downtown heritage homes feature brick construction with period details, while the 1980s-2000s suburban stock consists of typical builder-grade two-storey singles and splits. Brooklin's newer developments offer modern open-concept homes with 9-foot ceilings and contemporary finishes. The 1980s-90s homes represent the largest renovation opportunity, with dated kitchens, bathrooms, and finishes reaching their natural update cycle.
Development History
Whitby was established as a town in 1855, though settlement in the area dates to the 1830s. The historic downtown along Dundas Street and Brock Street retains much of its 19th-century character, with Victorian-era commercial buildings and surrounding residential streets featuring homes from the 1860s through early 1900s. Whitby served as the county seat of Ontario County and later the regional seat of Durham Region, giving it an institutional significance reflected in its stately older architecture. The town experienced major suburban growth beginning in the 1970s, with successive waves of subdivision development pushing north from the lakeshore and east along Dundas Street. The 1980s and 1990s saw extensive construction in areas like Blue Grass Meadows, Williamsburg, and the neighbourhoods along Rossland Road and Taunton Road. This era produced the majority of Whitby's current housing stock: builder-grade two-storey homes and side splits on suburban lots. Brooklin, a historically separate village north of Whitby's urban area, has experienced dramatic growth since the 2010s. Once a quiet rural hamlet centered around its agricultural fair, Brooklin is now one of Durham Region's fastest-growing communities with thousands of new homes built or under construction. This creates an interesting contrast for renovation contractors: Whitby offers everything from heritage restoration downtown to updating 1980s-90s suburban homes to addressing punch-list items in brand-new Brooklin construction.
Construction & Renovation Guide: Whitby
Whitby's renovation market is defined by three distinct segments. Downtown Whitby heritage properties require specialized knowledge of period construction, heritage regulations, and restoration techniques. These homes may have stone or brick foundations, original plaster walls, and heritage features worth preserving. Any exterior changes to designated heritage properties must be approved through the municipal heritage process. The vast suburban stock from the 1980s through 2000s represents the core of Whitby's renovation demand. These homes were built to code standards of their era but now show their age with dated kitchens featuring oak cabinets and laminate counters, basic builder bathrooms, and closed floor plans that feel restrictive by modern standards. Opening up main-floor layouts, modernizing kitchens and bathrooms, and finishing basements are the most common projects in these homes. Brooklin's newer construction generally needs less renovation work but owners frequently upgrade builder-basic finishes to premium materials. Custom backsplashes, upgraded lighting, finished basements, and landscape improvements are popular projects in this rapidly growing community. New homes in Brooklin typically have modern mechanical systems and 9-foot basement ceilings that make future finishing straightforward.

Typical Renovation Costs in Whitby
Estimates based on typical project scope. Actual costs vary by project specifics, material choices, and site conditions.
Unique Construction Challenges
- Downtown Whitby heritage properties require heritage permits for exterior alterations and may have stone or rubble foundations needing specialized assessment
- Rapid growth in Brooklin has strained infrastructure, and new-build homeowners may encounter punch-list deficiencies from builder construction requiring correction
- Clay till soil throughout Whitby causes seasonal ground movement that can affect foundations, particularly in older homes without modern drainage systems
- Many 1980s-90s homes have only 7-foot basement ceilings, limiting finishing options without costly underpinning
- Expanding municipal infrastructure in north Whitby and Brooklin may result in temporary water pressure or service disruptions during renovation projects
Foundation Types in Whitby
The majority of Whitby's housing stock has poured concrete foundations, standard for homes built from the 1970s onward. Basement ceiling heights are typically 7-8 feet in 1980s-90s homes and 9 feet in newer Brooklin construction. Downtown heritage homes may have original stone, rubble, or brick foundations from the 1860s-1900s period that require specialized assessment and potentially underpinning for major renovation work.
Common Foundation Issues
- Low basement ceilings (7 feet) in 1980s-era homes limiting finishing potential
- Heritage foundation deterioration in downtown properties
- Efflorescence and hairline cracking in 1980s-90s poured concrete
- Water seepage through aging waterproofing in 30-40 year old homes
- Window well drainage failures in clay soil
- Settlement cracking in areas with expansive clay deposits
Environmental Considerations in Whitby
Asbestos
LOW-MEDIUM RISKProbability in area homes: 30-60% in pre-1985 homes
Whitby's predominantly newer housing stock means asbestos is less prevalent than in older GTA communities. However, homes built before 1985 in the older sections of Whitby and downtown area may contain asbestos-containing materials. Heritage downtown properties from the 1800s-early 1900s almost certainly contain asbestos in later-added materials. All renovation work must comply with Ontario Regulation 278/05 under the Occupational Health and Safety Act regarding asbestos identification, handling, and disposal. Professional testing before renovation is required for any pre-1985 home.
Common Asbestos-Containing Materials
- Vinyl floor tiles and adhesive
- Pipe insulation and wrap
- Vermiculite attic insulation
- Drywall joint compound
- Exterior stucco or cement board
Radon
LOW RISKDurham Region has a relatively low radon risk compared to many parts of Ontario, with approximately 4.2% of tested homes exceeding Health Canada's guideline of 200 Bq/m3. Whitby's results are consistent with this regional average. However, radon concentrations vary house by house based on foundation type, soil conditions, and ventilation, so Health Canada recommends testing every home individually. A long-term radon test should be conducted as part of any basement renovation project, as finishing a basement can change radon dynamics in the home.
Soil & Drainage
Whitby sits predominantly on glacial clay till, a dense clay soil deposited during the retreat of the Laurentide Ice Sheet. This soil type has poor drainage characteristics and expands and contracts with moisture changes, placing stress on foundations over seasonal cycles. Properties near the Lynde Creek watershed, which runs through central Whitby, may have higher water tables and more variable soil conditions including silty and alluvial deposits.
Drainage considerations: Functioning sump pumps are essential in virtually all Whitby homes. Before finishing any basement, conduct a thorough moisture assessment through at least one full wet season. Ensure weeping tile, downspout extensions, and lot grading are all in good condition. Homes in lower-lying areas near Lynde Creek should have backwater valves installed to prevent sewer backup during heavy rain events. New construction in Brooklin generally has modern storm water management infrastructure.
All environmental assessments should be conducted by qualified professionals before renovation work begins. We coordinate testing and abatement as part of our renovation process.
Property Values & Renovation ROI in Whitby
Whitby's average home price of approximately $1,014,000 places it in the upper-middle tier of Durham Region communities. This price point means quality renovations offer meaningful equity gains. Kitchen renovations, bathroom updates, and basement finishing are the highest-ROI projects, with well-executed kitchen renovations typically recovering 75-85% of investment at resale. Secondary suites generate strong rental returns given Whitby's location between two post-secondary campuses and excellent GO Transit connectivity.
Market outlook: Steady growth supported by Durham Region's expanding employment base, ongoing Brooklin development, and continued demand from GTA buyers seeking value. Whitby benefits from its position as a well-established community with strong schools and amenities.
Building Permits & Regulations in Whitby
Building permits in Whitby are issued by the Town of Whitby Building Services division. All renovation projects involving structural changes, additions, basement finishing, or system modifications require building permits under the Ontario Building Code (OBC), with the 2024 OBC effective since January 2025 governing all new applications. Electrical permits are issued separately by the Electrical Safety Authority (ESA), and any gas or fuel-related work must be performed by TSSA-licensed technicians. Whitby has a straightforward permit process with online application options available.
Common Permits Required
- Building permit for structural changes, additions, and basement finishing
- ESA electrical permit for panel upgrades, circuit additions, and rewiring
- Plumbing permit for new fixtures, drain reconfiguration, and water service changes
- TSSA compliance for furnace, water heater, gas fireplace, and gas line work
- Heritage permit for exterior changes to designated heritage properties
- Site plan approval for certain additions and secondary suites
- Demolition permit if removing existing structures
Heritage Considerations
Downtown Whitby contains properties designated under the Ontario Heritage Act. Exterior alterations to designated heritage properties, including changes to facades, windows, rooflines, and significant additions, require approval from the Town of Whitby Municipal Heritage Committee. Interior renovations generally do not require heritage approval unless they affect the structural integrity or heritage attributes of the building. Consult the Town's heritage property register to determine if your property is designated or listed.
Zoning Notes
Whitby's zoning bylaw permits secondary suites and additional residential units in most residential zones, consistent with provincial housing policy. Properties in Brooklin and newer subdivisions are subject to site-specific zoning provisions that may affect lot coverage, setbacks, and building height. Downtown Whitby's mixed-use zoning allows for residential intensification in certain areas.
Applicable Codes & Standards
- Ontario Building Code (OBC) — Provincial building standards applicable to all renovation work
- ESA (Electrical Safety Authority) — All electrical work requires ESA permits and inspection
- TSSA — Gas and fuel-related work requires TSSA-licensed technicians
- Ontario Heritage Act — Heritage properties may require additional approvals
Key Renovation Considerations for Whitby
Check whether your property is on Whitby's heritage register before planning any exterior renovations. Heritage approval adds time to the project timeline but protects property values in the long run.
The majority of 1980s-90s Whitby homes have 7-foot basement ceilings. If you plan to finish your basement, assess whether the existing height meets OBC requirements for habitable space (minimum 6 feet 5 inches clear with 6 feet 8 inches at ducts and beams), or budget for underpinning if you want full-height ceilings.
Clay soil conditions make waterproofing a priority. Address any foundation moisture issues before investing in basement finishing. A failed waterproofing system can destroy a finished basement.
Many 1980s Whitby homes have galvanized steel drain stacks and polybutylene supply lines. Plan to replace these aging systems during major renovations to prevent future plumbing failures.
Brooklin homes, though new, may have builder-grade finishes that homeowners want to upgrade. Ensure any modifications do not void your Tarion new home warranty coverage during the warranty period.
Secondary suites are permitted in most Whitby residential zones. A basement apartment can generate $1,200-$1,800 monthly rental income while adding significant property value, making it one of the best renovation investments available.
When renovating older Whitby homes, budget for potential asbestos testing and electrical panel upgrades. These unseen costs catch many homeowners off guard but are essential for safety and code compliance.
Frequently Asked Questions: Renovations in Whitby
How much does it cost to renovate a kitchen in Whitby?
Kitchen renovations in Whitby typically range from $35,000 to $80,000 depending on the scope of work and material selections. A mid-range renovation including new cabinetry, quartz countertops, tile backsplash, and updated appliances generally costs $45,000-$65,000. Larger projects involving wall removal for open concept layouts, island additions, or premium materials like custom cabinetry will reach the higher end. With Whitby's average home price around $1,014,000, quality kitchen renovations offer excellent return on investment.
Do I need a heritage permit to renovate my downtown Whitby home?
It depends on the type of work. If your property is designated under the Ontario Heritage Act or listed on Whitby's heritage register, exterior alterations including changes to windows, siding, rooflines, and significant additions require heritage approval from the Town's Municipal Heritage Committee. Interior renovations generally do not require heritage permits unless they affect structural elements or designated heritage attributes. We recommend checking your property's heritage status with the Town of Whitby planning department before beginning any renovation planning.
Can I finish the basement in my 1980s Whitby home if the ceilings are only 7 feet?
Yes, 7-foot ceilings can work for a finished basement, though the result will feel more compact. The Ontario Building Code requires a minimum 6 feet 5 inches of clear height in habitable basement rooms, with 6 feet 8 inches required under beams, ducts, and other obstructions. If your existing ceiling height meets these minimums after accounting for finished flooring and any ceiling treatment, you can proceed. For full-height 8 or 9-foot ceilings, underpinning or bench footing is required, which adds $15,000-$40,000 to project costs but creates a significantly more comfortable space.
What renovation projects add the most value to Whitby homes?
In Whitby's market, kitchen renovations, bathroom modernizations, and basement finishing consistently offer the strongest return on investment. Kitchen renovations typically recover 75-85% of their cost at resale while making the biggest impact on daily living. Basement finishing, especially creating a secondary suite, adds both living space and potential rental income of $1,200-$1,800 per month. For heritage downtown properties, thoughtful restoration that preserves period character while modernizing systems commands premium prices from buyers seeking character homes.
Is Brooklin in Whitby a good area to invest in renovations?
Brooklin is one of Durham Region's fastest-growing communities with strong property values and excellent long-term appreciation potential. While most Brooklin homes are new enough to not need major renovations, popular investments include finishing basements with 9-foot ceilings for additional living space, upgrading builder-grade kitchen and bathroom finishes to premium materials, and adding custom landscaping and outdoor living features. The newer construction makes renovations straightforward since infrastructure and mechanical systems are modern and code-compliant.
