No pressure. No cost. Get a Free Quote →Fixed-Price Proposal
You receive a detailed, itemized planning proposal. Once the scope is defined, the written agreement records the price, allowances, exclusions, and change process.
Scope and changes in writing.Permits & Build
We help identify the permit path for your address and coordinate applicable inspections where that work is included in the approved scope. The City controls permit and inspection decisions.
Permit-aware. Documentation-led.Handover
Final walkthrough, punch-list completion, and handover of the records and workmanship terms that apply to the approved scope.
Documented handover.How We Protect Your Project
Every approved project starts with the address, the intended use, and the scope: what does the property need, what does the current authority path require, and what should be documented before construction begins?
OAF works on basement developments, legal suites, and garages across Calgary and Airdrie. Each property brings different existing conditions, access, utilities, design decisions, and approval questions. The useful starting point is a property-specific review, not a generic package presented as if every address were the same.
"Documented scope comes first."
When the scope is sufficiently defined, a written fixed-price agreement records the committed work, allowances, exclusions, and price before construction starts. If the property or the owner's decisions add work outside that scope, the change is identified and approved in writing rather than hidden inside a vague day-rate quote.
The OAF Standard is simple: make the agreed permit path, inspections, documents, and handover responsibilities visible. Where that coordination is part of the approved scope, the team prepares the applicable submissions, keeps required inspection steps visible, and provides the records and workmanship terms that apply to the finished work. The City controls permit, inspection, and occupancy decisions.
What Calgary Homeowners Say
They quoted us a fixed price for our basement development and stuck to it. To the dollar. The crew was professional, the site was always clean, and they handled every permit and inspection without us having to chase anything.
We had three other contractors quote our legal suite. OAF was the only one who walked us through the full permit process upfront. No surprises during the build, and the final inspection passed first time.
Our garage build came in exactly on the timeline they promised. What impressed us most was the communication. Weekly updates with photos. You could tell they actually cared about getting it right.
Calgary Suite Incentive Guidance
Calgary has separate programs for in-home secondary suites and detached backyard suites. The City currently lists the Secondary Suite Incentive Program (SSIP) as waitlisted and says funding may not be available; the Backyard Suite Incentive is offered while funds last. OAF can help scope a permit-ready project and check the current requirements with you, but the City makes all eligibility and funding decisions.

Questions Calgary Homeowners Ask
It means the approved written scope, allowances, exclusions, and change process are documented before construction starts. Materials, labour, permits, inspections, and project management are itemized where they apply. If the property reveals a condition outside that scope, we explain the options and obtain written approval before proceeding.
We review the project details, confirm whether Calgary or Airdrie is the right service area, and follow up to discuss fit and the next step. A site assessment may be recommended before a written proposal. Timing depends on project scope, property access, and the information available; there is no obligation to proceed.
A lifestyle basement may use a $45,000 planning entry point, while a legal-suite project may use a $58,000–$140,000 planning range. These are not quotes: square footage, existing conditions, layout, code requirements, permits, finishes, allowances, and exclusions determine the approved written scope and price.
Permit requirements depend on the address, proposed work, suite status, and current City process. We help identify the likely permit path, coordinate drawings and submissions within the agreed scope, and keep inspection steps visible; the City makes the permit and occupancy decisions.
The City of Calgary Secondary Suite Incentive Program can reimburse eligible safety work up to $10,000 when intake, funding, and property requirements apply. The City currently lists new applications as waitlisted, and the City, not OAF, decides eligibility and payment. Treat any amount as unconfirmed until the City confirms it.
A project-specific construction allowance may fall within an 8–16 week range after required approvals, but the address, scope, revisions, inspections, selections, and material lead times control the actual schedule. Permit review is separate and City-controlled. The written proposal should identify the dependencies and milestones that apply to your project.
Where permit coordination is part of the approved scope, we help prepare submissions, track review comments, and coordinate required inspections with the project team. The City controls approvals, inspection outcomes, and occupancy decisions, so the exact path is confirmed for each address.
We serve all Calgary neighbourhoods and screen Airdrie projects for fit. Our most active areas include Tuscany, Auburn Bay, Cranston, Mahogany, Legacy, Killarney, Altadore, and Airdrie. Nearby-area requests are secondary and are reviewed during the qualification call.
OAF Construction Corp. is listed as City of Calgary licensed and WCB-covered; current insurance documentation is available on request. For SSIP work, OAF can help with planning and documentation, but the City does not maintain an approved-contractor list and makes the eligibility decision.
