ARU Contractor London Ontario: What To Check Before You Hire

An ARU contractor can help turn a backyard-suite idea into a buildable plan, but the quote is only useful if the property has already been screened. Before you hire, check the lot, servicing route, permit path, rent-cap math, and City loan rules that can change the project cost.

Check the property before you spend on plans

Use the lot, loan, rent-cap, and servicing screens to decide whether the next step should be design work, a builder conversation, or more research.

  • Check the address
  • Review the loan rules
  • Confirm the rent math
  • Budget the hidden costs

A Good ARU Contractor Quote Starts With The Property

The best contractor conversation is not just about finishes or model size. It starts with the site: zoning, setbacks, lot coverage, service routing, access, grading, trees, permits, rental licensing, and whether the project fits the funding rules.

If the quote does not separate model price from site-specific work, it is not yet a decision-ready number.

What To Screen Before Paying A Deposit

A deposit can make sense once the project path is clearer. Before that, homeowners should screen the practical constraints that usually change contractor scope.

  • Confirm the zoning code and whether the property is in an eligible residential zone
  • Check rear and side setbacks before choosing a unit shape
  • Estimate lot coverage using the existing home, garage, additions, and proposed ARU
  • Map water, sanitary, hydro, gas, and internet routes
  • Ask what is included, excluded, provisional, or site-specific in the quote
  • Confirm whether the project depends on the $45,000 forgivable-loan path

Why Contractor Prices Can Change After Site Review

A simple model price can change once the contractor sees servicing, access, grading, utility capacity, tree conflicts, drainage, or permit requirements. Use the ARU cost guide to separate the base unit from hidden project costs before comparing quotes.

The Contractor Path Still Has To Fit The Loan And Rent Rules

If the project depends on the City incentive, the contractor conversation should connect back to the $45,000 ARU loan guide and the CMHC rent cap calculator. A buildable unit is not automatically a fundable or profitable unit.

The useful question is not only 'can this be built?' It is 'can this be approved, funded, licensed, rented, and held under the program rules?'

Questions To Ask An ARU Contractor

Use these questions before you treat a quote as final.

  • What site assumptions are baked into this price?
  • What utility work is included, excluded, or still unknown?
  • Who confirms zoning, setbacks, lot coverage, and permit drawings?
  • How are change orders handled if servicing or access is harder than expected?
  • Does the quote account for rental licensing, inspections, and development charge review?
  • If I want the City loan, when should I apply relative to design and construction?

FAQ

Common questions, answered plainly

Should I talk to an ARU contractor before checking zoning?

You can talk to contractors early, but do not rely on a quote until zoning, setbacks, lot coverage, servicing, access, permits, and funding rules have been screened.

What should an ARU contractor quote include?

A useful quote should clarify the base unit, site work, utility connections, design and engineering, permits, inspections, exclusions, allowances, and unknown site-specific risks.

Does hiring a contractor mean the $45,000 ARU loan is approved?

No. Contractor selection does not approve the City loan. The project still needs to follow the application timing, owner-occupancy, affordability, rent-cap, licensing, and permit rules.
