Existence, property-tax payment and utility connections do not establish authorised construction or permission to extend.
Compare the building, licence and drawings
When viewing land with buildings, record what exists and request documents for each stage. Obtain licences, recognition instruments, approved drawings and amendments where available, connecting them with the property. A decision without attachments may be insufficient to establish whether it covers the terrace, upper floor or rear extension. Commission a technical comparison of authorised and actual construction, clearly identifying areas, uses and discrepancies. Do not presume regularity because the building appears in the cadastre or receives utilities; those records serve their own purposes. Where documents are missing, enquire through a legitimate channel with the responsible archive and retain the response. The initial conclusion should identify supported elements, discrepancies and outstanding questions rather than label the entire building unlawful without analysis. This inventory supports valuation of the actual property and a route for proposed works, instead of purchasing solely from photographs or assurances that everything is up to date. Keep the measured condition distinct from the legal interpretation of each discrepancy.
Understand what recognition addresses
Decree 1077 regulates recognition of existing buildings constructed without the relevant licence subject to its conditions. It should not be treated as automatic regularisation for every work or permission to build first and request documents afterwards. The professional should examine use, history, age, restrictions and technical requirements, including relevant exceptions or specific regimes. Avoid copying an online cutoff date without checking the current provision and factual situation it addresses. A recognition instrument may impose obligations that still need fulfilment; receiving it does not allow them to be ignored. It also does not replace ownership assessment or resolve neighbouring disputes. Obtain an explanation of what the procedure would cover in the actual case and what would remain outstanding. If the purchase depends on obtaining it, reflect that uncertainty in negotiation. This guide supports documentary review but cannot determine whether an authority may recognise a particular building from the seller's marketing information. The conclusion needs the complete circumstances rather than an assumption based on age alone.
Review restrictions before funding a procedure
Investigate environmental protection, risk, public space and other conditions affecting procedures for the building. Law 388 addresses protection land and determinants that do not disappear because construction has stood for years. Obtain review of recognition rules and location-specific decisions, identifying relevant exclusions or conditions. An old materials invoice is not sufficient proof of eligibility, and absence of a known sanction is not authorisation. Where orders, proceedings or requirements exist, obtain the complete documents and assess their status. An architectural quotation does not guarantee overcoming a legal restriction. If an area's boundary is uncertain, seek mapping and technical clarification before designing extensions. The result should explain which procedures can be assessed and which facts prevent a conclusion. This allows a decision on commissioning documents, changing the project or negotiating different purchase conditions without presenting an unevaluated administrative result as certain. Keep relevant restrictions connected to the particular building footprint rather than assuming a general answer covers every part of the property.
Separate existing construction from a future extension
Recognition of existing construction does not equal permission for another floor, extra room or change of use. Show present condition and proposal on separate drawings and ask the adviser to determine procedures requiring coordination. Decree 1077 distinguishes construction categories, and the current framework needs checking when applying. An extension requires assessment of municipal rules, structural capacity, access and utilities as relevant. A lot containing a small home does not automatically permit double its footprint. If the seller offers to deliver a completed upper level, include design, relevant permissions and verification in the transaction assessment. A purchaser may receive physically completed works with documentary or technical obligations still outstanding. Identify who assumes them and the result needed before the relevant payments. Separating current and proposed conditions prevents a future drawing from describing recognised work or cadastral area from being presented as remaining development capacity. The contract, valuation and technical assignment should all use the same distinction when describing what exists and what remains to be done.
Assess safety and strengthening within their own scope
Obtain technical assessment where the project changes loads, affects structure or incorporates a building with insufficient records. Law 400 establishes the earthquake-resistant framework and relevant responsibilities; a supplier visit should not become a complete structural diagnosis. Define investigation, inputs and limitations with the professional. Strengthening may require specific procedures and does not itself recognise the whole building. Decree 1448 of 2026 changes certain Decree 1077 categories, including matters requiring checking for intervention and reconstruction within the regulated situations. Do not apply an extraordinary measure to every building merely because it lies in the same department. Obtain an explanation of scope and current status before invoking it. If the report recommends works, identify design, budget, sequence and verification of performance. Do not commission the additional floor before assessing the structure. Financial decisions require understanding what can be retained and what remains dependent on studies or further interventions. The technical conclusion should be tied to the actual design rather than a general promise that reinforcement will always be possible.
Example: an extension appears for tax purposes but lacks support
A purchaser views a home with an extension adding rooms and area. The seller shows an updated property-tax bill and says it regularised everything. Review finds approved drawings for a smaller building and needs to assess the executed extension, its date, use and technical conditions. The professional requests documents and determines whether recognition, another route or adjustments should be considered without predetermining the outcome. The purchaser includes evidenced costs and timing before fixing the final price. This hypothetical case does not claim every cadastral difference is an infringement or that the extension can be recognised. It shows that tax information and planning permission serve different functions. Where the transaction depends on a building having specified records, the preliminary agreement should describe them and provide legally reviewed consequences. Area increasing commercial value needs explanation in its physical, documentary and technical dimensions. The file should also distinguish confirmed findings from questions still awaiting the relevant authority or professional conclusion.
Organise documents, costs and responsibilities
Prepare a matrix showing procedure, responsible person, input document, expected result and dependency. Include surveying, technical evaluation, municipal enquiries and other necessary evidence with current quotations. Do not invent one regularisation tariff or a guaranteed approval period. If the seller arranges documents before completion, define verification of their scope and consequences if additional works are required. Preserve versions so submitted drawings match the building and reviewed proposal. Ask who holds each procedure and which steps are appropriate when ownership changes. If an authority returns an application or requests information, examine the actual document instead of assuming another payment is enough. Separate confirmed costs from items dependent on diagnosis. An organised route may avoid duplicated work but does not make an excluded procedure available. This clarity supports comparison between purchasing with alterations, reducing the project or choosing better-documented property. The buyer should understand both the work being commissioned and the remaining uncertainty at every stage.
Verify the result and outstanding obligations
On receiving an instrument, review the building or part it covers, drawings, status and conditions. Verify required works and evidence of compliance under the relevant procedure. Store the result with title, cadastral information and sale documents while preserving their different functions. Before another extension, reassess rules and technical capacity; the previous file does not authorise every alteration. When advertising, describe existing, authorised or recognised area and material outstanding issues accurately instead of promising automatic regularisation to the next purchaser. This guide received editorial review on 14 October 2026 and considers September 2026 amendments within their factual scope. It determines neither recognition eligibility nor structural safety for a particular building. The competent authority and professionals must examine location, history, use and actual conditions. A useful result explains what is established and what must be addressed to retain, occupy or intervene in the building under the applicable framework. Keep those conclusions readable for future owners and advisers rather than scattered across unrelated certificates.
Existing-building and proposed-change worksheet
Start with what exists, then describe what you want to change. Each row separates records, recognition, enlargement and safety. This worksheet does not legalise works or establish availability of a route.
| Review question | Evidence to record | Next action |
|---|---|---|
| What exists physically, and what is documented? | Areas, levels, uses, known dates, plans, licences, recognition and observed differences between them. | Prepare a comparison for each building part; mark received, checked and still-missing information. |
| Which situation needs assessment of recognition? | Available records, location, use, restrictions and conditions requiring professional assessment. | Check eligibility and limits of the current route; age or property-tax payment does not establish recognition. |
| What does the new project add or alter? | Additional area, levels, use, structure, installations and relationship to the existing building. | Identify the procedure applying to the change; recognising existing works does not itself authorise enlargement. |
| Which technical assessment does the intervention need? | Loading programme, known condition, structural records, study scope and responsible professional. | Commission assessment before contracting an additional floor; connect strengthening, design and verification with its findings. |
| Is a special 2026 measure proposed? | Invoked provision, regulated situation, project evidence and current status checked with the adviser. | Verify amendment scope and required records; being in the same department does not establish individual eligibility. |
