Ottawa Property History Reports
Ottawa property history reports pull from City of Ottawa open data: every construction, demolition and pool enclosure permit the City has published since July 2011, the zone under the new Zoning By-law 2026-50, the City's floodplain overlay, whether the sewer serving the address is combined or separated, and fire station and hydrant proximity. Coverage is the amalgamated City of Ottawa.
What's Included in an Ottawa Property History Report
Building Permits Since July 2011
Construction, demolition and pool enclosure permits from the City of Ottawa's open data permit files, from July 2011 to the most recent month published. Each permit shows its issue date, the work described, and the declared value of the work. Permits issued before September 2024 also name the contractor where the City recorded one. The City publishes the issue date only, so every permit is labelled Issued: the record does not say whether the work was inspected or completed, and the report does not imply it.
Zoning Under By-law 2026-50
The zone and its name under Zoning By-law 2026-50, the City's new comprehensive zoning by-law, read from the City's own zoning layer, with a link to the part of the by-law that governs that zone. Parts of the by-law are under appeal at the Ontario Land Tribunal; where an appeal covers the address, the report says so and gives the zone under the previous By-law 2008-250.
Floodplain Overlay
Whether the address falls inside the City of Ottawa floodplain overlay, which carries the regulatory floodplain mapping of the Rideau Valley, South Nation and Mississippi Valley conservation authorities. If the overlay cannot be read when the report is generated, the report says the flood status is unavailable rather than showing a clear.
Servicing, Fire and Hydrants
Whether the sewer at the address is combined or separated, and the year the water and sewer mains on the street were installed, from the City's own pipe layers; the distance to the nearest fire station; and the distance to the nearest hydrant.
Radon Risk
Radon prevalence context for Ontario, drawn from the Cross-Canada Radon Survey.
What an Ottawa Report Does Not Cover
Year built is often not available. Ontario assessment data is licensed through MPAC rather than published openly, and the only construction dates the City publishes are on its heritage register. A construction year is shown where the permit to construct the home falls inside the permit record, which begins in July 2011, or, for a listed heritage home, from the register's date, usually a circa year and labelled as an estimate. It is never inferred from a permit for a garage, addition or pool, and the age-based guidance that depends on a construction year is withheld rather than estimated.
Lot size, assessed value and Ontario land title are not part of the report. Permits issued since September 2024 name no contractor, because the City's current permit file has no contractor column. The report shows what the public record supports and names the rest as unavailable rather than leaving a gap unexplained.

Frequently Asked Questions
What is a property history report in Ottawa?
A property history report compiles publicly available City of Ottawa open data, including building permits since July 2011 with the declared value of the work, the zone under Zoning By-law 2026-50, the City floodplain overlay, whether the sewer is combined or separated, and fire station and hydrant proximity, into a single document for any residential address in Ottawa.
How far back do Ottawa permit records go?
To July 2011. The City of Ottawa's open data permit files begin then, and the report includes every year since. Work permitted before July 2011 is not in the public record the report draws on; a buyer wanting earlier history should ask the City directly.
Does the report show whether an Ottawa permit was closed?
No. The City of Ottawa publishes the issue date of each permit but not its inspection or closing status, so every permit is labelled Issued. The report says so rather than implying the work was finalled.
Does the Ottawa report show year built?
Where the permit to construct the home is in the record, which begins in July 2011, or where the home is on the City of Ottawa heritage register, which dates about 4,600 properties, usually as a circa year. Newer homes and listed heritage homes are usually dated; other older homes usually are not. Ontario assessment data is licensed through MPAC and is not published as open data. Year built is never inferred from a permit for a garage, addition or pool.
Which zoning by-law does the report use?
Zoning By-law 2026-50, the City of Ottawa's new comprehensive zoning by-law, read from the City's zoning layer. Where an appeal at the Ontario Land Tribunal covers the address, the report flags it and shows the zone under the previous By-law 2008-250, because the new zone may not yet be in effect there.
Does the Ottawa report include flood risk?
Yes. The report checks the address against the City of Ottawa floodplain overlay, which carries the regulatory floodplain mapping of the Rideau Valley, South Nation and Mississippi Valley conservation authorities. It reports the mapped classification; it does not predict flooding or confirm insurability.
What is not included in an Ottawa report?
Lot size, assessed value and Ontario land title are not included, year built is shown only where a construction permit or a heritage register date is on record, and permits issued since September 2024 name no contractor. The report shows what the public record supports and names the rest as unavailable rather than leaving a gap unexplained.
