The trees had a permit process of their own

a Victoria infill self-build

A Victoria infill self-build shared its lot with three bylaw-protected trees -- and the City's Tree Protection Bylaw required an arborist report and cash-or-letter-of-credit security for the trees before the building permit would issue, an environmental approval track entirely separate from the building permit itself.

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

The problem

Victoria's Tree Protection Bylaw requires tree information and, where a development-related application like a building permit is involved, a tree permit before construction of a principal building can proceed -- and where replacement trees or the retention of protected trees are made a condition of that tree permit, the City requires security in the form of cash or a letter of credit.

What the tree permit process actually required

  • An arborist report identifying every protected tree on the lot and assessing the impact of the proposed construction on each one
  • A tree permit setting conditions -- retention, protective fencing during construction, or replacement where a tree could not be saved
  • Security in cash or letter of credit wherever replacement trees or retention was made a condition, separate from any other closing costs

None of this touched the municipal building permit's own review of the structure itself. It ran as its own approval track, through the City's parks department rather than its building division, and had to clear before the building permit would issue.

The numbers

Once the arborist report and tree permit conditions were satisfied, the underlying construction mortgage math was ordinary.

The uninsured construction takeoutAmount
As-improved lending value$920,000
Down payment (20%)-$184,000
Construction mortgage$736,000

Payment at the qualifying rate (6.92%), 25 years$5,119/mo
Property tax$440/mo
Heat (lender estimate)$175/mo
Car loan$290/mo
TDS39.6%

39.6% left comfortable room on the household's own income, and BC's property transfer tax on the $920,000 purchase came to $16,400. The mortgage ratios were never close to a limit -- the tree permit's own arborist report and security condition were what actually held the building permit back.

The solution

A submortgage broker licensed under BC's Mortgage Services Act treated the tree permit's own approval track as a distinct condition on the file, running through the City's parks department rather than the building division.

First, had the borrower retain a certified arborist to survey the lot before the building-permit application was even drawn up, since the report's findings on protected trees could change where the foundation itself could sit.

Second, confirmed with the City which trees the arborist report and the bylaw's own diameter threshold actually protected, rather than assuming every mature tree on the lot qualified.

Third, arranged the tree permit's own cash-or-letter-of-credit security separately from the file's other closing costs, so it did not compete for the same funds at the same stage of the file.

The outcome

The arborist report confirmed two of the three protected trees could be retained with protective fencing during construction, security was posted for the one requiring replacement, the tree permit and building permit issued together, and the construction mortgage funded at 39.6% TDS.

Because this is an uninsured construction mortgage, CMHC's ratio maximums do not apply directly; the TDS figure is informational.

What to take from this file

  • 01A municipal tree protection bylaw can require its own permit, arborist report and security before the building permit issues. It runs through the parks department, not the building division -- track it as its own approval.
  • 02Retain the arborist before the building-permit application is drawn up, not after. The report's findings on protected trees can change where the foundation itself can be sited.
  • 03Confirm the bylaw's own protected-tree threshold rather than assuming every mature tree on the lot qualifies. Diameter and species thresholds vary and are set by the municipality's own bylaw.
  • 04Arrange tree-permit security separately from the file's other closing costs. It should not be left to compete for the same funds at the same stage.
