Does cited mean verified by the municipality?

No. A citation points to evidence; it does not prove municipal confirmation, legal interpretation or permit eligibility.

How often does Bucky refresh local rules?

Refresh timing varies by source and municipality. Check the date on the relevant record and the official source for later amendments.

Can I rely on a missing rule as permission to build?

No. Missing data remains unknown. Confirm the applicable rules and approvals with the municipality and the appropriate professional.

How Bucky sources and cites local rules

Bucky connects preliminary site analysis to municipal parcel records, zoning maps, bylaws and other source datasets. A citation identifies the source behind a fact, with a section reference where available. Coverage and freshness vary by municipality and layer.

A sourced answer supports professional review; it does not establish municipal approval or permission to build.

What cited means

A cited zoning fact includes a source reference you can inspect. Where section-level evidence is available, the reference identifies the governing provision. Read its definitions, exceptions and site-specific conditions alongside the number.

Cited does not mean municipality-confirmed, legally verified or current after an amendment. Bucky is preliminary decision support, not a permit, appraisal or professional certification.

Where the data comes from

Parcel boundaries and identifiers come from municipal and regional GIS and other available registries. Zoning districts come from official maps; zoning rules come from bylaw or ordinance text. Overlay and development-activity records depend on the sources available for each municipality.

Where the source is a PDF, structured facts retain references to the source document. A missing rule, unmapped overlay or unavailable source is a gap to resolve, not permission to proceed.

Coverage and refresh dates

Coverage is checked by address and layer. A live municipality does not establish that every parcel has every fact. Check parcel, zoning, overlay and activity coverage separately.

There is no single refresh cadence for all sources. Consult the date and source attached to the relevant record and check the municipality for later amendments.

Worked example: 29 Wychwood Ave, Toronto

These are the facts for 29 Wychwood Ave, Toronto. Each source link opens the City of Toronto record.

29 Wychwood Ave, Toronto

Fact	Bucky returned	Official source	Applies when
Parcel	Parcel 5361021, stated area 162.06 m²	City of Toronto, Property Boundaries	Identifies the lot. It is not a survey and does not confirm title or frontage.
Zone	R	Zoning By-law Map: R (d0.6)	The map label carries a density value of d0.6 and no site-specific exception.
Maximum floor space index	0.6	By-law 569-2013, 10.10.40.40(1)(A)	Set by the d0.6 in the zone label. Regulations (1)(C) and (1)(D) remove the limit for houseplexes, buildings with a secondary suite, and some buildings on a major street.
Minimum rear yard setback	7.5 m	By-law 569-2013, 10.10.40.70(2)	Applies in the R zone. A lawfully existing building can keep a smaller setback under 10.5.40.71.
Minimum side yard setback	0.9 m	By-law 569-2013, 10.10.40.70(3)(A)	For a detached or semi-detached house or houseplex, a townhouse whose units all front a street, or an apartment building 13.0 m tall or less. Other building types need 7.5 m under (3)(B).
Minimum front yard setback	6.0 m	By-law 569-2013, 10.10.40.70(1)	Only if front-yard averaging in 10.5.40.70(1) does not apply. Averaging uses the front yards of buildings on abutting residential lots within 15.0 m, so check the neighbouring houses.
Maximum number of storeys	Not limited by this regulation	By-law 569-2013, 10.10.40.10(3)(B)	The Height Overlay Map shows no ST value for this lot. Height and main-wall limits still apply.

What the worked example does not establish

Maximum height is not in the table because the returned value did not match the City’s records. Bucky returned 10.0 m, the fallback in 10.10.40.10(1)(B) for a lot with no HT value. The Height Overlay Map shows HT 13.0 for this lot, so 10.10.40.10(1)(A) sets the limit. For floor space index, Bucky cited 10.10.40.40(1)(B), the clause for a zone label with no d value; (1)(A) governs here, and the value is the same.

Bucky did not resolve these facts for this lot: maximum lot coverage (not extracted), the flanking side yard (conditional, unresolved) and parking (not on file). Overlays, building depth, main-wall height, servicing and permits need a separate check.

Bucky’s stored copy of these sections predates wording added by By-laws 648-2025 and 848-2025. Check the City’s consolidated text for later amendments.

This is a record check for one lot, not a feasibility result or a zoning opinion. It does not show that any building would comply or be approved.

When a source is ambiguous or missing

Keep unknown facts and assumptions separate from sourced facts. Conflicting provisions, missing coverage and uncertain applicability need professional or municipal review before a decision.

Bucky does not claim universal coverage, municipal endorsement, or replacement of a planner, architect, lawyer or appraiser. Report an issue with the address, the cited source and the disputed fact so it can be investigated.
