Start with your question

What do you need to figure out?

Four different questions. Four different next steps. The right City source matters more than a big number.

Your next best step

Start with the proposed work and the property.

The number of permits across Toronto does not establish which rules apply to your lot. Your dimensions, zoning and proposed scope can change the answer.

  1. 01

    Choose the type of work you are considering.

  2. 02

    Match your actual Toronto address and review the sourced conditions.

  3. 03

    Confirm open conditions with Toronto Building before ordering materials or accepting a quote.

Check my project

BuildRules offers guidance, not permit approval.

Did this help you find the right next step?

Building a renovation team? Find a local professional. Claiming or buying a listing never affects an official permit answer.

Current dataset snapshot

What the City has on record today.

201,876

Rows in Toronto’s active building applications and permits dataset. One row does not necessarily represent one distinct project, property or permit issued.

What the number is not

It is not a count of permits issued this month, renovation starts, approved projects or unique homeowners. Active records can span multiple application years and statuses.

Selected categories · Not a ranking

A closer look at common project types.

These are exact category labels used in the City dataset, not a complete breakdown and not evidence that a particular property can be developed.

Small Residential Projects

45,280dataset rows

Building Additions/Alterations

32,119dataset rows

New Houses

11,866dataset rows

A snapshot, not a timeline

An application status is not a construction milestone.

These are selected, exact STATUS values found in the active Toronto dataset. They are neither a complete distribution nor counts of distinct projects. A City status may change after publication.

Application On Hold

1,898

An application is on hold in the published record. The dataset cannot tell you what must be resolved for a particular property.

Permit Issued

38,234

The record is marked issued. It does not establish that work started or finished.

Inspection

123,118

The record is marked for inspection activity. Use the City’s status tool for the actual file.

Revision Issued

19,972

The record indicates a revision was issued. Revisions may create additional rows for the same underlying project.

Do not add these categories to estimate total permits issued or construction starts. To check the actual progress of a specific application, use the official City status service.

Turn data into a decision

Citywide activity cannot answer your property question.

Whether you can build a deck, addition or garden suite depends on your address, proposed work, zoning and the conditions of the applicable rules. Start a property check before ordering materials or requesting a quote.

How these figures are calculated

BuildRules queries the City of Toronto’s public CKAN datastore for the total number of records and separate totals filtered by exact PERMIT_TYPE or STATUS field values. Results are cached for up to six hours. A value may change after a City update. We do not collect private application files, infer permit approval, or calculate neighbourhood trends from this snapshot. An active register loses closed records, so a difference between two retrievals cannot be described as changes in construction activity. Historical trends need a separately validated, longitudinal dataset.
