Illas: local guide and property context
A sourced introduction to Illas, its official settlement geography and the evidence used on this property-area page.
Official geography
The official INE register places Illas in Asturias province under municipality code 33030. The linked structured record provides a recorded municipal area of 25.51 square kilometres and a reference coordinate of 43.4959, -5.9681. The coordinate is a municipal reference point, not a property, parcel boundary or radius from which local claims are inferred.
Settlements and local form
The current IGN Nomenclátor extract records 11 official population nuclei for Illas. The imported source records are dated through 2025-10-20. The entry explicitly marked as the municipal capital is La Caizuela, at a recorded elevation of approximately 169 metres. Other population-bearing nuclei in the extract include La Peral (195 residents in the cited settlement record), La Llaguna (167 residents in the cited settlement record), Piñella (113 residents in the cited settlement record), Zanzabornín (61 residents in the cited settlement record), and Calavero (58 residents in the cited settlement record). Nomenclátor entries describe settlement geography; they are not listing totals, neighbourhood boundaries or evidence of homes currently available for sale.
How this guide keeps the evidence local
The data sections below keep Illas’ municipality evidence separate from wider province and regional comparisons. This prevents similarly named places in other provinces from being blended together. Where a municipality-level series is unavailable, the page labels the province fallback explicitly; current NLS asking inventory remains separate from completed-sale, demographic and cadastral evidence.

Current Catastro coverage for Illas municipality includes 806 recorded buildings and 682 recorded dwellings, with an average recorded build year of 1949. These are cadastral records, not a count of homes currently for sale.

Sources, periods and how to read this analysis
Completed-sale snapshot. Consejo General del Notariado / Penotariado aggregate for the stated scope. Price measures use 9 price-informed sales from 14 total recorded transactions. It is a current snapshot fetched 2026-08-03 21:39:29, not a historical point.
Transaction activity. MITMA quarterly housing transmissions, shown as published counts with no scaling or extrapolation.
Registered-price context. Colegio de Registradores quarterly statistics for the labelled comparison scope. Aggregate values are never relabelled as municipality or neighbourhood values.
Population and income. INE series for Illas municipality through 2023. Aggregate percentages and averages are population-weighted where appropriate.
Physical stock. Dirección General del Catastro building records. Counts describe recorded stock, not homes currently for sale.
Administrative registers. Official energy-certificate and, where available, tourism-register entries are matched to official geography; coverage is not a model of unregistered stock.
Geographic scope. Official municipality pages use their INE code. Legacy area-taxonomy pages inherit only a municipality or province scope that resolves unambiguously; no market value is derived from a listing location.
Current listings. The NLS active public inventory, shown separately as asking inventory and never blended into completed-sale statistics.
Images. Wikimedia Commons files are selected through Wikidata municipality records. Each photograph retains its creator, reuse licence and source link.
This is aggregate market context, not a property valuation, cadastral assessment, legal opinion or forecast. Non-institutional deed samples and commercial portal asking-price benchmarks are excluded from the analysis.
