Ajax Renovation Contractor · Reformity Inc.Basement & Home Renovations in Ajax
Kitchen and bathroom work in Ajax's 1970s and 1980s houses often reaches walls, plumbing or windows, and once it needs a permit the Town's renovation checklist asks for fully dimensioned drawings carrying the designer's qualification information, an Energy Efficiency Design Summary, and heat-loss calculations if space is added. Homeowners can draw their own plans for simpler jobs, but the Town suggests a qualified designer when structural changes or several Building Code requirements are involved, which is where our drawings come in.

Renovations permits in Ajax
Renovations that need a permit go in under Ajax's renovation checklist, with fully dimensioned drawings carrying the designer's qualification information and an Energy Efficiency Design Summary, and a basement apartment needs its own additional-dwelling-unit permit with fire-separation details — Reformity prepares the drawings and manages the application.

Basements & second units
Finishing a basement goes through a building permit in Ajax; it's one of the Town's most common residential applications, with a guide that includes the application form, checklist and sample drawings. A basement apartment (an additional dwelling unit) and a below-grade entrance are separate permit types, each with its own checklist.
Town of Ajax: building permitsAdditional dwelling units
Zoning allows up to three additional dwelling units with a house where the zone permits them (up to three inside it, or up to two inside plus one detached), but not on land the conservation authority deems hazardous, and each needs an unobstructed path at least 1.2 m wide to the driveway, street or lane. The Town counts a finished basement with a separate entrance and cooking facilities, wet bars included, as one.
Ajax Zoning By-law s.4.4 (PDF)Second & third units
Ontario's Planning Act allows up to three units on a serviced urban residential lot with a detached, semi or townhouse: three in the house, or two in the house plus one in an ancillary building like a garage. Each new unit needs a building permit.

Ajax Renovations FAQ
Quick answers.
You can, but if the basement also has a separate entrance, the Town classes it as an additional dwelling unit: finished basements with a separate entrance and cooking facilities, wet bars included, count as ADUs. An ADU has to meet zoning, Building Code and fire safety rules, and a basement finished as part of your home can't be rented out as a separate legal unit.
