Calgary infill lot due diligence before you buy
Check a Calgary infill lot before purchase: parcel rules, title, survey, access, demolition, utilities and the fit between the site and your proposed home.
An infill lot should be tested against the home you intend to build before you commit to it. Confirm the parcel's planning information, review title and survey documents with the right advisers, and investigate access, demolition and service assumptions.
Write the proposed home brief first
A site cannot be assessed in the abstract. Record the type of dwelling, approximate size, garage requirements, outdoor priorities and any accessibility needs. Mark which features are essential and which can change.
Use that brief to ask a designer or builder for an early fit study. A desirable location may still require compromises in parking, daylight, privacy or usable outdoor area. Discovering those compromises before purchasing is more useful than producing detailed drawings afterward.
Check current property information
Use the City of Calgary's property and development resources to identify the parcel and its current planning information. Ask the applicant to verify applicable requirements for the actual proposal; a nearby infill is context, not evidence that the same design will be approved on your lot.
Avoid relying on a broad statement that an entire neighbourhood allows a particular form. Where information conflicts, record the question and obtain clarification before treating the concept as feasible.
Ask the legal and survey questions
Provide your lawyer with the title and registered interests relevant to the purchase. Ask which restrictions or rights may affect the proposed use of the property. Have a qualified survey professional advise whether the available survey information is sufficient for design.
Do not infer boundaries from fences, landscaping or a listing image. The position of existing structures and grades can matter to the new design, and the cost of obtaining accurate information belongs in the feasibility budget.
Create a parcel review worksheet
Use a simple register to prevent assumptions from becoming facts as the project moves between advisers.
| Question | Evidence to request | Who to consult |
|---|---|---|
| Does the intended form fit? | Current parcel rules and a concept study | Designer and municipal planning staff |
| Are boundaries and interests clear? | Title, registered documents and survey advice | Lawyer and surveyor |
| Can services support the proposal? | Existing service information and connection requirements | Utility providers and project consultants |
| Can construction work on this site? | Access and staging plan | Builder |
| What must be removed? | Existing-condition and demolition review | Qualified demolition and project specialists |
Price demolition and access explicitly
Ask what investigation is needed before removing the existing structure, including any material testing recommended by qualified specialists. Request a scope that distinguishes removal, disposal, service disconnections and site preparation. Those are cost-planning questions; they should not be assumed to be covered by a new-home square-foot rate.
Map where deliveries, equipment, temporary services and bins could go. Discuss how neighbouring property and any retained site features will be protected. Restricted access can change the work sequence even if the proposed home is straightforward.
Understand the permit sequence
The City's new-house guidance distinguishes development approval, building approval and demolition. It states that developed-area projects require a development permit and explains the demolition application sequence. Ask the project applicant to confirm the current requirements and dependencies for this site before setting a construction date.
Make the purchase decision from an open-items list
Collect the findings in one document. For each uncertainty, identify the next investigation, likely decision date and potential effect on the design or budget. Ask your advisers which issues should be resolved before a purchase commitment and which can be managed later.
A useful outcome is a clear go, revise or investigate-further decision tied to your brief. It is not simply a statement that the parcel is attractive. Compare the cost of making the property usable with other sites you are considering.

Frequently asked questions
Does a neighbouring infill prove what I can build?
No. Confirm the rules, conditions and approval route for your own parcel and design. Neighbouring construction may have different constraints or approvals.
Can a builder review a lot before I purchase?
Ask a suitable builder and designer to assess the proposed home against the site. Legal, survey, utility and technical advice may also be needed.
