SeLoger Property Data Starts With the French Use Case
SeLoger is operated by Digital Classifieds France, Groupe SeLoger. Its current legal notice identifies DIGITAL CLASSIFIEDS FRANCE as publisher of seloger.com. Its current privacy/legal context identifies AVIV Group GmbH as parent-group context. (SeLoger mentions légales)
For a property-data team, the useful first question is not simply: “Can we scrape SeLoger?” It is: “Which French property records do we need, and what permitted source path supports that use?”
A useful project should define:
- sale, rental, or new-build scope
- target cities, arrondissements, postcodes, or other French geographies
- apartment, house, land, commercial, or other property types
- search-result versus detail-page fields
- asking-price and €/m² requirements
- DPE/GES requirements
- rental charges and deposit fields where relevant
- location-precision requirements
- whether recurring observations are needed
- intended downstream use
- source authorization or licence
- destination
NenoData’s current Real Estate Data Scraping service NenoData’s current Real Estate Data Scraping service scopes projects around required sources, markets, fields, schedules, intended use, access conditions, and destination. Source support and field availability should be confirmed before implementation rather than assumed.
What SeLoger Data May Be Relevant?
The exact fields depend on the approved source, property category, page type, transaction type, and engagement scope.

| Listing identity | listing ID, source URL, source status | Source dependent |
| Transaction type | sale, rental, new-build, commercial where separately scoped | Keep explicit |
| Pricing | asking sale price, rent, €/m², source-visible charges | Preserve commercial meaning |
| Property | property type, surface area, rooms, bedrooms, floor, lift, furnishing, year built | Availability varies |
| Energy | DPE, GES, heating, energy source, estimated energy cost where displayed | Listing dependent |
| Location | city, postcode, arrondissement, neighbourhood, displayed address/location | Precision varies |
| Publisher | agency/company identity where permitted | Personal/contact data separately reviewed |
| Observation metadata | observed_at, first_seen, last_seen | Only where recurring access is approved |
| Source metadata | source URL, transaction type, original source field labels | Useful for lineage |
This is an illustrative requirements schema. It is not a guarantee that every SeLoger listing exposes every field, nor a claim that NenoData already maintains a production SeLoger dataset.
Sale, Rental, and New-Build Records Need Different Schemas
SeLoger-related data should not be flattened into one generic price record.
Sale
- asking sale price
- EUR
- asking €/m²
- surface
- rooms
- property type
- DPE/GES
- location
Rental
Current SeLoger rental pages demonstrate that fields such as loyer charges comprises, loyer hors charges, provisions pour charges, charges forfaitaires, dépôt de garantie, €/m², DPE, GES, furnishing, floor, lift, heating, and source-visible availability can appear on listings. Not every rental record supplies every one of these fields.
- rent including charges
- rent excluding charges where displayed
- provisions for charges where displayed
- fixed/forfait charges where displayed
- deposit
- furnished/unfurnished status
- surface
- €/m²
- DPE/GES
- availability
New-build: New-build or development records may require a separate project/programme structure. Do not silently model a development programme as an ordinary second-hand resale listing. A normalized master schema can exist, but the source transaction or record type must remain explicit.
French Rental Pricing Should Preserve Charge Context
A single generic field called rent can remove important French rental semantics. Where the approved source supplies the detail, preserve the relevant charge fields.
Potential schema fields
rent_including_charges_eurrent_excluding_charges_eurcharges_eurcharges_typedeposit_eurrent_per_sqm_eurobserved_atFrench rental concepts preserved
- Do not collapse those concepts into one monthly number.
- Populate them only where the approved source actually supplies them.
- Do not imply that every SeLoger rental record contains each field.
NenoData’s Rental Market Data Scraping service supports approved-source rental workflows where source availability is confirmed during scoping.
EUR and €/m² Are Different Fields
Total asking value is not interchangeable with unit-price metrics. A sale or rental record may preserve:
- total asking price or rent
- EUR currency
- €/m²
- surface
- observation timestamp
Potential schema fields:
asking_sale_price_eurasking_rent_eurasking_price_per_sqm_eurcurrencyprice_originalobserved_atIf NenoData calculates a derived €/m² value rather than using a source-displayed value: use the correct price field, use the appropriate source area field, define the calculation rule, and preserve whether the metric is source-provided or derived. Do not calculate €/m² from an ambiguous area basis.
NenoData’s Data Cleaning & Standardization service supports agreed field mapping, transformation rules, and validation for EUR and €/m² fields.
DPE Is a First-Class French Property Field
The Diagnostic de performance énergétique (DPE) is an important French property-data concept. Current SeLoger listings can expose:
Source fields (potential)
- DPE class
- GES/emissions class
- heating type
- energy source
- construction year
- estimated annual energy-cost ranges
Schema fields
- dpe_class
- ges_class
- heating_type
- energy_source
- energy_cost_min_eur
- energy_cost_max_eur
- dpe_observed_at
- Treat DPE as a source-displayed field.
- Do not infer a missing DPE class.
- Do not infer a missing GES class.
- Do not manufacture regulatory meaning beyond what the source actually displays.
DPE Data Needs Provenance
DPE data can support:
Provenance fields preserve the origin of the rating:
dpe_classges_classdpe_sourcedpe_observed_atsource_listing_idsource_urlThis lets downstream users distinguish a DPE observation shown on a listing from energy data obtained from another approved regulatory or property source.
Asking Price Is Not a Completed Transaction Price
SeLoger is a property-listing marketplace. A displayed property price should therefore be treated as an advertised or asking value, not automatically as a completed transaction amount.
A listing asking price is not a completed transaction price.
Listing asking price
- advertised/marketplace value
- set by seller or landlord
- subject to change before completion
- asking_price_eur / asking_rent_eur
- source: SeLoger marketplace page
Completed transaction price
- actual agreed sale/rent amount
- requires a separate approved source
- transaction_price_eur
- never inferred from a listing price
- keep provenance separate
Potential schema fields:
asking_price_eurasking_price_per_sqm_eurtransaction_price_eur from another appropriate sourceprice_sourceobserved_atThis distinction matters for:
A listing asking price must not be silently presented as evidence of the amount ultimately paid. If completed transaction information is required, use another approved transaction/property-record source and keep its provenance separate.
Asking Price, Market Benchmark, and Valuation Are Different Concepts
A source page may also show market context or €/m² comparison information. Keep distinct:
Potential schema fields:
asking_price_eurasking_price_per_sqm_eurmarket_reference_per_sqm_eurvaluation_eurtransaction_price_eurPopulate each only when supported by the approved source. Do not silently substitute market-reference values for the listing asking value.
Surface, Rooms, and Building Attributes Should Preserve Their Meaning
Potential property fields may include:
- Keep source meaning intact.
- Do not turn missing values into guesses.
- A structured schema can preserve both source text and normalized values.
For example: floor_original = “5ème étage” may coexist with floor_number = 5 when that transformation is unambiguous. If it is not unambiguous, retain the original value and leave normalized output unresolved.
French Location Precision Should Be Preserved
A French listing may expose:
Exact street-level location must not be assumed. Current SeLoger listings may explicitly withhold precise address information for confidentiality.
Potential schema fields:
citypostcodearrondissementneighbourhooddisplayed_locationlocation_precisionDo not:
- manufacture exact addresses
- infer exact coordinates
- turn approximate location into precise location
Location precision must remain source-aware.
SeLoger’s Current CGU Explicitly Oppose Automated Data Mining
The SeLoger CGU (effective February 26, 2026) state that Digital Classifieds France Digital Classifieds France expressly exercises its right to oppose text-and-data mining.
The CGU define that activity as automated extraction, collection, and analysis of digital text/data and explicitly include methods such as:
The opposition applies broadly to content, data, and websites made available by the company.
The same current legal framework also restricts technical extraction, substantial database extraction/use/storage/reproduction, and other unauthorized use of site/service content.
This is not:
The correct project question is: “What authorized source or use basis supports this requirement?”
NenoData does not market:
Does SeLoger Have an Official Public Listing API?
No unrestricted official public SeLoger marketplace-listing API was verified during this research.
Do not say:
- SeLoger has no API whatsoever.
- SeLoger provides a public bulk listing API.
- NenoData integrates with SeLoger’s official API.
Keep open the possibility that private, commercial, partner, or customer-specific integrations could exist under separate arrangements.
Official SeLoger Access and Third-Party Scraper APIs Are Different Things
Third-party vendors may market products as SeLoger APIs, scraper APIs, extraction APIs, or parser APIs.
Third-party products can indicate
- buyer expectations
- potential output schemas
- developer demand
- technical feasibility
Third-party products do not establish
- SeLoger authorization
- text/data-mining rights
- commercial reuse rights
- storage rights
- redistribution rights
- NenoData access
Do not describe third-party extraction products as official SeLoger APIs.
Authorized SeLoger Data Paths NenoData Can Evaluate
A SeLoger-related business requirement can remain useful even where unrestricted direct automated collection is not appropriate.
SeLoger’s CGU expressly oppose automated text-and-data mining. An appropriate authorized basis is required first.
Need French property data
Authorized basis confirmed?
Yes
Proceed within documented rights
explicit SeLoger authorization
customer-owned listings
agency/developer feed
licensed French dataset
No direct SeLoger
Re-scope to licensed, permissioned, or customer-authorized French property source
Explicit SeLoger authorization or licence
If the customer has documented permission or licensing covering the intended use, scope the workflow only to those documented rights. Confirm fields, pages/record types, geography, storage, retention, transformation, internal use, public display, redistribution, and cadence.
Customer-owned listings
Agencies, developers, owners, or property companies may already control their own property/listing information. NenoData can clean, standardize, validate, and deliver customer-controlled information without claiming access to the broader SeLoger marketplace.
Agency/developer feeds
Approved feeds can be transformed into a French property schema with explicit transaction types, price semantics, DPE/GES, location, and source attribution.
Customer-supplied files
Potential inputs include CSV, Excel, JSON, CRM exports, database exports, and property-management exports.
Licensed French property datasets
Where direct SeLoger use is unsuitable, evaluate a licensed French property dataset against the same business requirement.
Other approved French property sources
A requirement may be re-scoped to another public, permissioned, customer-authorized, or licensed property source where appropriate.
Multi-source French property workflow
Where several approved inputs are involved, map them into a common schema with field mapping, source attribution, validation, matching, deduplication, and exception handling.
NenoData’s Multi-Source Data Aggregation service supports agreed external and customer-authorized sources rather than arbitrary source use.
NenoData’s Data Sources page explicitly treats source feasibility and permitted collection method as scoping questions rather than guarantees.
Agency Identity and Contact Data Need Separate Review
Agency/company identity may be relevant for market-coverage analysis, source attribution, and listing provenance. Personal contact information is a different data class.
Personal contact information—including:
—requires review against:
Do not turn personal/contact fields into a headline SeLoger capability. Do not make an independent legal-compliance determination on the page.
One-Time Dataset or Recurring Listing Observations
Where an approved source arrangement permits repeated retrieval and retention, the workflow may use a snapshot or recurring observation model.
One-time requirements
- French housing-market research
- rental-market analysis
- DPE research
- investment screening
- listing normalization
- customer-data migration
Recurring observations
Potential observation fields:
- observed_at
- first_seen
- last_seen
- asking price
- asking rent
- source status
- DPE where source-visible
- listing availability
Recurring observations must remain conditional on approved repeated access and retention.
Do not claim:
- an existing NenoData SeLoger archive
- historical SeLoger coverage
- daily refresh by default
- hourly refresh
- real-time refresh
- a fixed SeLoger SLA
Asking-Price Monitoring Should Preserve Observation Context
Where permitted, a recurring record may include:
source_listing_idobserved_atasking_price_eurprevious_observed_price_eurasking_price_per_sqm_eurlisting_statusA change in advertised price is a marketplace listing observation, not a completed transaction-price change. Do not silently upgrade listing history into transaction history.
Delivery Depends on Source Rights
NenoData’s Custom Data Pipelines service can support:
- CSV
- Excel
- JSON
- API-ready records
- databases
- data warehouses
- webhooks
- scheduled or recurring feeds where scoped
For a SeLoger-related project confirm:
- 1.approved source
- 2.authorization/licence
- 3.permitted fields
- 4.storage rights
- 5.retention rights
- 6.downstream use
- 7.redistribution rights
- 8.privacy constraints
- 9.destination
“API-ready” means NenoData can structure records for downstream programmatic use. It does not mean NenoData has a SeLoger marketplace API relationship.
How an Authorized SeLoger Data Workflow Would Work
- 1
Define the requirement
Specify sale, rent, or new-build; target French geography; property types; required fields; DPE/GES requirements; rental-price fields; one-time or recurring requirement; intended use; and destination.
- 2
Confirm the access/rights basis
Identify whether the project uses explicit SeLoger authorization, customer-owned listings, agency/developer feeds, licensed French property data, another approved source, or customer-provided files.
- 3
Define the record model
Represent listing, transaction type, property attributes, pricing, energy, location, and observation as separate explicit fields.
- 4
Define rental-price semantics
Where supported, preserve rent including charges, rent excluding charges, charges, charge type, deposit, and €/m². Do not populate unsupported rental concepts.
- 5
Define DPE handling
Preserve source-displayed DPE, GES where supplied, heating/energy fields where supplied, provenance, and observation timestamp. Do not infer missing DPE/GES.
- 6
Define price semantics
Separate asking sale price, rent, €/m², market-reference values, valuations, and transaction data from other approved sources.
- 7
Ingest through the approved path
Use only permissioned, customer-controlled, licensed, or otherwise authorized inputs.
- 8
Normalize and validate
Apply agreed rules for EUR, €/m², property type, rooms, surface, floor, furnishing, DPE/GES, postcode, city, arrondissement, nulls, duplicate candidates, source attribution, and exceptions.
- 9
Deliver within approved rights
Prepare the permitted structured output for CSV, Excel, JSON, API-ready schema, database, warehouse, webhook, or scheduled/recurring feed where the approved source arrangement permits it.
Potential Business Requirements
These are customer requirements, not evidence that SeLoger grants unrestricted source rights.
French housing-market analysis
Normalize appropriately authorized property records across cities, arrondissements, property types, and price bands.
Rental-market research
Structure approved rent, charges, surface, furnishing, DPE, location, and observation fields.
DPE and energy analysis
Analyze source-displayed DPE/GES records without inferring missing ratings.
Asking-price benchmarking
Compare asking price and €/m² while keeping them separate from transaction evidence.
Listing monitoring
Observe approved asking-price changes, listing-status changes, and availability changes where recurring access is permitted.
Investment research
Prepare approved property records for internal screening.
PropTech workflows
Map approved French property records into search, analytics, enrichment, and internal product schemas.
Multi-source French property intelligence
Combine customer-owned, licensed, permissioned, or otherwise approved French property sources into one consistent schema with source attribution.

not unrestricted SeLoger scraping.
NenoData Is Not Affiliated With SeLoger or AVIV
NenoData does not claim affiliation with SeLoger, partnership with Digital Classifieds France, partnership with AVIV Group, official SeLoger marketplace API credentials, SeLoger authorization, an existing SeLoger dataset, an existing SeLoger historical archive, or authorized-scraper status. Only state such a relationship if it is separately documented.
