Design and structure
Structural alterations, assessed and coordinated for your València home
A larger opening or changed layout starts with understanding the building. We coordinate the competent independent professionals, the agreed design and the construction team, with the required permissions and inspections identified before work begins.
Structural alterations in València: how the rules apply
Each rule below comes from a municipal, regional or national text listed in the sources. The note says what it means for this job; open a rule to read its full wording.
Permission and paperwork
- When a building project is required
An intervention that alters the overall structural system is one of the LOE's project triggers; a local opening with a designed lintel may not be. The appointed designer records which applies.[4]
Rule wording
LOE article 2 requires a project for existing-building works that alter architectural configuration, including specified substantial changes to exterior composition, volume or the overall structural system, and changes of characteristic use. It also covers interventions affecting protected elements of listed buildings; not every interior refit meets these tests.
- Compulsory college visa
If the alteration needs a LOE project, its execution project and final-works certificate carry the professional college's visa.[5]
Rule wording
For building work, a professional college visa is compulsory only on the execution project and the final-works certificate of works that need a project under LOE article 2.2, on those documents in legalisation procedures, and on demolition projects that do not use explosives (art. 2).
Community and building
- Seismic acceleration 0.06 g (NCSE-02)
With València listed in the standard's annex, the structural designer states whether NCSE-02 applies to the modified structure, given its exceptions, and records why.[6]
Rule wording
The seismic standard NCSE-02 lists València with a basic seismic acceleration of 0.06 g and a contribution coefficient K of 1.0 (Annex 1). The standard does not apply to buildings of moderate importance and has further exceptions depending on the building and its structure, so the structural designer establishes whether and how it applies.
- Notice to the community (LPH 7.1)
Notice alone never covers structural work in a block: article 7.1 bars alterations that impair the building's safety or general structure.[9]
Rule wording
An owner must notify the community’s representative before works inside a flat. Article 7.1 allows those alterations only if they do not impair the building’s safety, general structure or exterior configuration, or prejudice another owner’s rights; notice alone does not authorise changes to common elements.
- Three-fifths (LPH 17.4)
Specified structural alterations need three-fifths of all owners and participation quotas; we prepare the technical summary the administrator circulates before the meeting.[9]
Rule wording
Article 17.4 includes a three-fifths vote of all owners and participation quotas for specified structural or common-element alterations, including terrace enclosure, with affected owners’ consent where applicable. Compulsory works and other specific statutory routes must be considered separately.
On site and at handover
- Architect and technical roles
In a residential building the architect leads the project and works direction, the technical architect directs execution, and a structural engineer can contribute calculations within their competence.[4]
Rule wording
For residential building work within the LOE’s project requirements, the law assigns the architectural project and works direction to an architect, and material execution direction to a technical architect. Specialist designers and other technicians act within their legal competence and the agreed project team.
- Safety coordination
If the propping, demolition and steel installation involve more than one company or several self-employed workers, a safety and health coordinator is appointed before work starts.[7]
Rule wording
The promoter must appoint a safety and health coordinator during construction when more than one company, a company with self-employed workers, or several self-employed workers take part. Appointing a coordinator does not remove the promoter’s own responsibilities.
- Check for asbestos before disturbing materials
Opening up older construction can disturb materials of unknown composition; anything suspect is assessed before demolition starts.[8]
Rule wording
Before demolition or maintenance, employers must identify materials that may contain asbestos, using information from the owner where appropriate. Suspected material requires assessment before disturbance; covered asbestos work is subject to specialist controls, an approved work plan and company registration as applicable.
- Working hours (noise ordinance)
Breaking out masonry and cutting steel are scheduled within the ordinance's hours, and neighbours are told in advance which days they fall on.[10]
Rule wording
València’s 2023 noise ordinance allows works in buildings that affect the public domain from 08:00 to 22:00, Monday to Saturday, and from 09:30 to 22:00 on Sundays and public holidays, with exceptions for urgent or authorised work (art. 31). Noisy domestic renovation is also banned at night: 22:00 to 08:00 from Sunday to Thursday, and 22:00 to 09:30 on Fridays, Saturdays and the eves of holidays (art. 30).
- Completion records and the building book
Keep the structural calculations, the approved design, inspection records and agreed changes; a future buyer or the community may ask for them.[4]
Rule wording
For building works covered by the LOE, the completed project with approved changes, reception record, identification of participants and use and maintenance instructions form the building book delivered to users. The documents required for a smaller renovation depend on its scope and installation work.
Do you need a permit?
València’s 2026 ordinance has three routes. Which one your job takes depends on what it touches and on the building.
Declaración responsable
UR.LC.140 includes certain structural modifications that neither replace nor reinstate principal structural elements, in non-catalogued buildings and with the technical documents and direction the procedure requires. [1, 2] [1]
Licence
Work that replaces or reinstates principal structural elements is outside UR.LC.140; depending on its classification it needs a licence, or a declaration backed by the certification article 233.2 allows. A catalogued building adds its heritage route. [3, 2] [3, 2] [3]
The Ajuntament has the final word. We confirm the route for your home before we quote, and we never start works ahead of it.
Three districts, from the municipal record
The 2025 municipal housing sheet records the share of dwellings built in 1980 or earlier. It is context for the district, not a survey of your building.
District 1
70.4%[14]
Dwellings built in 1980 or earlier
Ciutat Vella
Inside the BIC historic ensemble [11], a structural change also has to respect the building's protection under the PEP catalogue [12]; we start with the catalogue sheet.
District 11
71.8%[15]
Dwellings built in 1980 or earlier
Poblats Marítims (Poblados Marítimos)
The original Cabanyal expansion is a BIC historic ensemble of about 28.5 hectares [16], with its own special plan [13]; structural work on a house there is assessed against both.
District 2
84.6%[17]
Dwellings built in 1980 or earlier
L’Eixample (Ensanche)
Most L’Eixample dwellings are recorded as built by 1980, so a proposed opening usually meets older construction that needs investigation first; inside Russafa's catalogued core, the nucleus conditions apply too [18].
Open the district page for protection rules, barrios and the questions that apply there.
Establish what the building can accommodate
Start with the proposed change and the construction it affects. A wider kitchen opening, a stair alteration or roof work can involve different design and permission requirements. UR.LC.140 includes certain structural modifications that do not replace or reinstate principal structural elements. A competent technician must establish the intervention, documentation and correct permission route before demolition; a structural change is not automatically covered by a simple interior-works declaration.[1, 2] We coordinate the assessment before treating the idea as an agreed construction scope.
The inspection should record its limitations. Where concealed construction remains uncertain, the professional team identifies whether authorised opening-up or specialist investigation is needed. A neighbouring property’s alteration is not proof that the same detail is suitable for your home.
Appoint the right professional team
Whether the change makes the job a LOE project decides the appointments. [4] [4] The written appointments identify the designer, any required technical direction and the responsibilities of the construction team. Structural calculations, the overall residential project and site coordination must be addressed by professionals acting within their competence.
The agreed design covers the permanent intervention and the requirements for carrying it out. Temporary support and the sequence of operations are not details to improvise once demolition begins. Our wall-opening guide sets out the decisions to resolve before that stage.
Resolve permission and access
The municipal route is assessed for the actual intervention, including protection where relevant. [3] In a block, the proposed effect on structure and common elements must also be considered under the community rules. [9] [9]
We coordinate the agreed submissions and the information the administrator needs. An authority’s or community’s approval remains its decision. The construction programme follows those requirements and the practical arrangements for access, materials and any affected occupants.
Build to the design and record changes
Where several companies take part, a safety coordinator is appointed. [7] The responsible team establishes the construction and inspection arrangements before the affected work begins. If opening the building reveals something different from the design assumptions, the issue is referred back to the designer before the solution is changed.
Keep the approved design, relevant inspections and agreed revisions with the project records. [4] We coordinate making good and handover within the agreed refurbishment scope, so the structural intervention is connected to the finished rooms and the documents the owner receives.
How we run it
Free estimate
Send photos or a short video, or book a call. We tell you what the job involves and give a free estimate.
Visit
We visit the property, measure up and look at the building, the installations and the community’s rules.
Design and permissions
We agree the design, coordinate any required independent architect or engineer, and check municipal and community requirements.
Fixed-price quote
You get a fixed-price quote in writing, with the official fees and IVA shown separately.
Paperwork and works
We coordinate any required filing and prior approvals before the affected works start. Your project manager tracks progress, decisions and agreed changes.
Handover
We inspect the agreed work with you, record outstanding items and hand over applicable certificates, manuals and completion documents.
Your questions, answered
Can you tell from a photograph whether a wall is load-bearing?
A photograph is not enough to establish its role. The appointed professional reviews the construction and available information and identifies any further investigation needed before a design is fixed.
Does every structural change need the same permission?
No. The route depends on the actual intervention, the building and the applicable documentation or certification. Certain alterations and work replacing principal structural elements are treated differently, so the proposal must be assessed specifically.
Who designs and signs the structural work?
The appropriately qualified independent professional within the required project team. We identify their role and appointment; a contractor's coordination service does not replace regulated design or technical direction.
Can work start before the community has considered it?
The applicable community and municipal requirements must be resolved before the affected work starts. We coordinate the information needed and the construction programme around those decisions.
