An internal renovation may be exempt from a planning licence or prior notice, yet still be far from ready to start the next day. In Lisbon, there is a practical difference between an exempt type of work and a project that has prepared the building, contractor and neighbours properly.
The point most often missed is straightforward: Lisbon City Council states that notice of the start of works must be submitted up to five days beforehand, identifying the person or company responsible for carrying them out. Use that period to settle the decisions that prevent a difficult first day: material routes, lift protection, waste removal, working hours and communication with the condominium. Check the official process for notifying the start of works before booking deliveries or demolition.
First, confirm that the work is genuinely exempt
An internal intervention may be exempt where it does not affect the building’s structural stability, alter height, change the façade or roof shape, or remove façade tiles. That can cover many replacements of finishes, kitchens, services and lightweight partitions. It does not mean that every job inside a flat is free from checks.
Ask for a precise written scope: walls to be removed or built, water points, ventilation, electrics, openings, equipment and any visible external changes. Compare it with Lisbon’s guidance on works exempt from prior control. If the proposal touches structure, façade, roof, exterior tiles or the use of the unit, do not assume it remains exempt.
Lisbon also calls for extra care around listed properties, properties under listing, protection zones and listed groups or sites. A modest-looking intervention may follow a different route. Where there is doubt about restrictions, easements, use or viability, a prior information request is designed to clarify the position before materials are ordered.
Use the five days to formalise the start
Do not leave the notice until the day before. Confirm who is named as the person or company in charge, the actual start date and the exact address of the unit. If the first activity is stripping out, protective covering or equipment installation, treat that as the real start rather than choosing a more convenient date in the programme.
Keep a shared folder with the scope, site contact details, relevant insurance, delivery schedule and photographs of common areas before work begins. This is practical evidence. If there is a question about lift damage, an out-of-hours delivery or a change to the plan, the project can be discussed from records rather than memory.
If the design develops on site, do not accept the idea that every decision can simply be made during construction. The council distinguishes changes that remain outside prior control from those requiring an amendment to a submitted licence or notice. Review the guidance on building works subject to prior notice before a finish choice turns into a change to footprint, façade or use.
Speak to the condominium before the van arrives
Notifying the council does not replace coordination with the condominium. Write to the building manager with the planned start date, estimated duration, contacts, noisiest periods, intended use of the lift and material route. Attach a short description, such as “kitchen and service replacement, with no changes to the façade or structural elements”.
Check the deed of horizontal property and the building regulations too, where they exist. Work inside a unit can still affect the architectural appearance, common parts or shared systems. An outdoor unit, a new grille, façade discharge, door alteration or work on vertical stacks should not be treated as a purely private decision.
Ask for a clear response on building rules: lift booking, required protection, permitted hours, temporary storage, daily cleaning and access to meters or service risers. For a practical approach, see our guide to protecting lifts and shared areas during a renovation.
Map the route for materials and waste
Before ordering bags of mortar, boards, cabinets or appliances, walk the route from the street to the apartment door. Measure the lift, landings, stair turns and doorways. Confirm where the crew can unload without blocking a garage, pedestrian route or another resident’s entrance.
Set the sequence as well. Protection goes in first; bulky materials arrive next; delicate items follow when there is a safe place to store them. Leaving everything in the lobby or on the pavement creates hazards, delays and disputes that an hour of planning could have avoided.
Waste needs the same discipline. Separate materials for collection by an authorised operator, set a collection frequency and do not treat common areas as temporary storage. For an organised approach from the quotation stage, read our article on renovation waste, removal and street occupation in Lisbon.
If you occupy the street, treat it as a work front
An exempt renovation may still require scaffolding, a skip, stored materials, hoarding or lifting equipment. In that case, occupation of public space has its own rules; it is not an automatic extension of permission to work inside the apartment.
The occupation plan must show how the area is arranged, the pedestrian route, safeguards, vehicle access, equipment and temporary signs. The council identifies cases where a notification may be enough, including certain scaffolds that keep the pavement clear or maintain a minimum pedestrian width of 1.50 metres. Other cases require a licence. Check the requirements and information-board rules on the council page for public-space occupation for exempt works.
Do not schedule a skip on a “we will see” basis. Confirm its location, days, size, responsible company and a fallback plan if the street is restricted. On narrow Lisbon streets, this detail can decide whether the project starts or waits.
Put the first day in writing
The day before, send the contractor and manager a short note: arrival time, site contact, agreed access, unloading point, lift arrangements, waste plan and intended work. If demolition, water shut-off or electrical isolation is involved, state the expected duration and who will be told.
Photograph the lift cabin, landings, corridor and entrance door before materials are moved. Use suitable protective coverings without blocking fire equipment, exits or signs. Keep a clear route and remove materials at the end of the day unless there is an approved storage area.
Small renovation works gain momentum when their start does not rely on improvisation. Preparing the five days beforehand does not replace design, supervision or the rules that apply to a particular building. It creates the conditions to follow them without passing the cost of disorganisation to neighbours and workers.
