Short answers to common starting questions, with a clear route to the guide or service that can help you go further.
Use these answers to find the next useful page. The detailed guides explain the decisions and records behind each topic. Property-specific feasibility, design and approval questions need the appropriate professional or authority.
Getting started
Do I need to know exactly which service I need?
No. Describe the current basement, the intended use and the question you want answered. The enquiry form includes a choice for homeowners who are not sure yet.
Is family basement finishing the same as a legal suite project?
They can involve similar finishes but different intended uses and planning questions. Read the project comparison before deciding whether to request family finishing or new-suite construction.
Can an unfinished basement always become a separate dwelling?
That cannot be confirmed from its unfinished appearance. The property, layout, access, services and applicable requirements need review. Start with the requirements guide.
Existing basements and records
What if the basement was finished before I bought the house?
Gather the records you received and note what is missing. Do not assume the marketing description established approval. The existing-basement review explains how to begin.
Where can I check second-unit registration?
Use the City’s official registry resource and follow up with the City when the address or record is unclear. The registration-check guide explains how to record what you find and what still needs clarification.
Does a permit number mean all work is complete?
A permit reference identifies a record; you still need to understand its scope and the related inspection or closeout status. See the records comparison.
Will all existing finishes have to be removed?
Not necessarily. A review should distinguish visible conditions, documented work and concealed items that may need investigation. Ask how selective openings and restoration would be authorized in the corrective-work scope.
Drawings and approvals
Can I ask for drawings and permit coordination only?
Yes. Select that service and explain whether the project is a new suite, existing-basement review, entrance or family renovation. The drawings page lists responsibilities to clarify.
What should I prepare before speaking to a designer?
Gather available surveys, old drawings, permit references and a concise description of the proposed use. Use the permit preparation checklist to separate owner inputs from design deliverables.
Can this website confirm an approved ceiling height or window size?
No. A generic number does not establish compliance for a particular layout. The responsible designer should identify the applicable requirements and assess the actual conditions. See the requirements guide.
Does submitting drawings mean construction can start?
A submission is a review step. Confirm the applicable approvals and any conditions before proceeding with work that depends on them. The process guide explains the sequence.
Separate entrances
Is excavation always needed for separate access?
Do not assume so. Existing side access, a new opening and a below-grade stairwell are different routes to assess. Read the entrance comparison.
Does adding a separate entrance make the unit legal?
No. The entrance is one part of the project. The full arrangement and relevant records need review. The entrance service page explains how to coordinate it with the wider scope.
What information helps with an entrance enquiry?
Explain whether access already exists, the proposed basement use and any known site concerns. During follow-up, ask how to share photographs, drawings or a survey for the entrance assessment.
Budget and timing
Why is there no single basement price on the website?
A drawing package, existing-unit corrections and a complete build contain different work. The cost guide helps define the scope needed for a useful estimate.
How should I compare two quotes?
Compare the same drawings, rooms, inclusions, allowances, exclusions and responsibilities before comparing totals. Use the quote comparison worksheet.
Can the project timeline be guaranteed at the first enquiry?
A reliable schedule needs the assessed scope, design, approval dependencies and construction plan. The process page shows the stages the provider should consider.
Contact and information handling
Who will contact me after I submit the form?
Your details may be shared with an appropriate independent provider so they can respond to the requested service. Read about the enquiry service and confirm the provider’s identity during follow-up.
Does a form submission create a construction contract?
No. It starts an enquiry. Any assessment, quote or project agreement is established directly with the provider. The website terms explain that relationship.
Can I correct or withdraw my enquiry?
Use the contact details and explain the change. The privacy policy describes requests about information already supplied.

Windows, building systems and completion
Where can I find specific window and building-system questions?
Explore egress windows, fire and sound, plumbing, electrical and HVAC planning. Bring the relevant questions back to one coordinated design.
What if moisture needs attention before the renovation?
Start with the moisture guide and document the pattern before deciding on corrective work or finishes.
What comes after construction is finished?
Resolve the applicable inspection and closeout items, then follow the City registration steps for the second unit. Keep records for each stage.
