How to check São Paulo zoning in GeoSampa

Research into use or expansion in São Paulo needs to record which rule was consulted. A zoning abbreviation copied from an old page does not by itself explain what can currently be done on a property.

Read the notice before the result

The SISZON query warns about legal changes its information does not fully incorporate and directs users to GeoSampa and Gestão Urbana. That warning is part of the evidence: do not crop it out of a screenshot to display only a favourable code.

Open GeoSampa with the lot already identified. Retain the layer name, legend, query date and referenced instrument. If multiple planning layers appear, read their descriptions before combining colours. An apparent change may result from comparing different instruments or periods rather than a change affecting this specific lot.

Formulate a project question

Separate the existing situation from the intended intervention. “Opening a shop on the ground floor” and “increasing constructed area” require different questions, even at the same address. Record the proposed activity or modification and which parameters remain unconfirmed.

If two services display conflicting information, preserve both results with their dates. Seek an explanation of that specific discrepancy before estimating additional area or revenue. Your research should let someone else reproduce the query and locate the same parcel. The map organises the question; feasibility depends on the interpretation applicable to the lot and proposal, rather than the presence of a particular colour or abbreviation.

A building for practising the distinction

The verified Terraes record represents a 188.12 m² footprint at -23.54644, -46.63997. The query on 22 September 2026 returned this Overture record, release 2026-08-19.0. This is footprint area; it does not identify an apartment or establish rights over the land. Use the example to recognise which object you are reading before applying the official query to your property.

Continue with the other local guide or the country hub. The methodology explains evidence concepts; its specific models do not automatically transfer to this case.
