Finished is not the same as legal装修过，不等于合法

Many GTA basements have a kitchen, a bathroom and a tenant, but were never built or inspected as a second unit.GTA 很多地下室有厨房、有卫生间、也有租客，但从未按第二单元施工和检查。

Common problems, and how we solve them常见难点与解决办法

  • Ceiling too low层高不够

    Reroute ducts and bulkheads first. If that isn't enough, the floor is lowered with underpinning or bench footings.先调整风管和包管；仍不够时，通过托换基础（underpinning）或台阶式基础（bench footing）降低地坪。

  • Windows too small窗户太小

    Cut a larger opening and add a window well, so every bedroom has a window you can climb out of.扩大窗洞并加装窗井，确保每间卧室都有可以爬出的逃生窗。

  • No separate entrance没有独立入口

    A side or rear walk-down entrance is common. Where the layout allows, a protected shared exit can work instead.常见做法是在侧面或后面增设下沉式入口；布局允许时，也可以采用受保护的共用出口。

  • One furnace, shared ducts共用一台炉子和风管

    Ductwork is detailed so smoke can't travel between units, or each unit gets its own system, depending on the house.根据房屋情况，对风管做防烟处理，或为每个单元配置独立系统。

One lot, three homes一块地，三个家

Ontario allows up to three units on most serviced residential lots: the main house, a basement suite and a garden suite. ARVO designs and builds both additions, and checks the zoning for them together.安省允许大多数有市政配套的住宅地块建最多三个单元：主屋、地下室单元和后院花园屋。两种加建 ARVO 都可以设计和施工，并同时核查分区要求。

Questions homeowners ask业主常见问题

What makes a basement apartment legal in Ontario?在安省，什么样的地下室出租单元才算合法？
It is allowed by zoning, built under a building permit, meets the Ontario Building Code requirements for a second unit (fire separation, a way out, ceiling height, smoke and CO alarms, among others), passes inspections, and the permit is closed. Ontario's rules now allow up to three residential units on most serviced residential lots, so in most GTA neighbourhoods the question is whether your particular basement can meet the code.需要同时满足：分区规定允许、在建筑许可下施工、符合安省建筑规范对第二单元的要求（防火分隔、逃生出口、层高、烟雾和一氧化碳报警器等）、通过各阶段检查，并完成许可关闭（permit closed）。安省现行规定允许大多数有市政配套的住宅地块建最多三个居住单元，因此在 GTA 大多数社区，关键问题是您家的地下室本身能否达到规范要求。
My basement is already finished. Does it all have to come out?地下室已经装修过了，需要全部拆掉吗？
Usually not. Some areas often need to be opened so the inspector can see framing, wiring, plumbing and insulation, and the ceiling between units typically needs fire-rated drywall and sealed openings. We look at what can stay during the feasibility assessment.通常不需要。一般要局部打开墙面或天花，让检查员查看结构、电线、水管和保温；两个单元之间的天花通常需要换成防火石膏板并封堵开口。哪些可以保留，我们在可行性评估时会逐项判断。
How long does it take?整个流程需要多长时间？
Permit review time depends on the city and on how complete the drawings are when they are submitted. After the feasibility assessment we give you a schedule for your project, covering design, permit and construction.审批时间取决于所在城市以及提交图纸的完整程度。完成可行性评估后，我们会给出针对您项目的时间表，涵盖设计、报批和施工三个阶段。
What does it cost?费用大概多少？
The biggest cost drivers are lowering the floor if the ceiling is too low, cutting in egress windows, adding a separate entrance, and separating heating, ventilation and plumbing. A basement that already has good height and an entrance costs far less. The feasibility assessment ends with an itemized estimate.主要的费用来自：层高不足时降低地坪、开挖新的逃生窗、增加独立入口，以及分隔暖通和给排水系统。层高够、已有入口的地下室费用会低很多。可行性评估结束时，我们会给出分项预算。
Who prepares the drawings and the permit application?图纸和报批由谁负责？
Drawings are prepared by BCIN-qualified designers. We submit the application, answer the plans examiner's comments, and book the inspections through to permit closure.图纸由 BCIN 资质设计师出具。报批申请由我们提交，审图意见由我们回复，各阶段检查也由我们预约，直至许可关闭。
Can I have a basement suite and a garden suite?可以同时做地下室单元和后院花园屋吗？
On many GTA lots, yes: a main house, a basement suite and a garden suite can add up to the three units the province allows. We check the zoning for both at the same time, since that is also what ARVO builds in the backyard.在很多 GTA 地块上可以：主屋、地下室单元加花园屋，正好是省里允许的三个单元。我们会同时核查两者的分区要求，后院花园屋本身也是 ARVO 的主营业务。
Do you work in Chinese?可以用中文沟通吗？
Yes. Consultations, drawing reviews and site meetings can be in English, Mandarin or Cantonese.可以。咨询、图纸讲解和现场沟通都可以使用英文、普通话或粤语。
