Renovating for Holiday Rental in Spain: Costs, Rules, Priorities

Renovating a property for holiday rental in Spain starts with the paperwork, not the paint. Before you spend anything, confirm your town hall and your building’s owners allow tourist use. Then budget roughly €15,000 to €35,000 for a 70 m² coastal apartment, plus furnishing, and spend it on what guests see in photos and what regulators check on inspection.

This guide covers the order of work, the money, the 2026 legal and tax changes that affect your numbers, and the renovation choices that actually move bookings.

TL;DR

Check use compatibility with local zoning and your community of owners before any renovation contract. A fully renovated flat that cannot be registered is a trapped investment.
For a typical 70 m² coastal apartment, research puts renovation at €15,000 to €35,000, with tourist-ready furnishing at €4,000 to €7,500 on top.
Spend on photogenic, durable and easy-to-clean finishes, reliable Wi-Fi, climate control and self check-in, not on residential-style luxury.
Recalculate your yield with 2026 taxes in mind: no residential rental reductions, and possible municipal IBI surcharges.

Check the rules before you pick a tile

The most expensive renovation mistake is not a bad contractor. It is renovating a property that cannot legally operate as a tourist rental. Three layers decide this.

Municipal zoning and use compatibility

Andalusian tourism authorities require the property to fit the municipal urban plan before you list it. The most common reason for a refused registration is that nobody verified use compatibility first. If the town council has restricted tourist use in your zone, a perfect renovation does not fix it. Ask the town hall’s urban planning department in writing, and keep the answer.

Regional habitability conditions

In Andalusia, Decree 31/2024 sets the conditions for registering a tourist dwelling. Among them are a minimum area per guest of 14 m², a set number of bathrooms for larger capacities, and climate control (heating, cooling or both, depending on the months you operate). These conditions shape your floor plan. If you plan to sleep six in a flat that only supports four, you need to know that before demolition, not after.

A habitability certificate is a separate document that often comes up in older buildings. We explain what applies now in our guide to the certificado de habitabilidad in Andalucía. For the registration process and its benefits, see our piece on holiday home registration in Spain.

National registry and platform enforcement

Spain is rolling out a single national registry for short-term rentals under EU Regulation 2024/1028, as the Ministry of Housing explains. Enforcement is real: according to reporting on the 2026 measures, the Ministry notified platforms in February 2026 to remove more than 86,000 listings without a valid registration number. Operating without registration now means automatic takedown notices, not a quiet grey area.

Your building’s owners

Since 3 April 2025, a reform of the Horizontal Property Law gives communities of owners more control over holiday rental activity in their buildings, according to Minut’s legal guide. Read your community statutes and check the minutes of recent meetings before buying or renovating in a block. If the rules are unclear, ask a lawyer who handles horizontal property cases.

What a holiday rental renovation costs

There is no single figure, because scope drives everything. The ranges below combine the research we found for coastal Spain with the way budgets usually split.

Item	Typical range (70 m² coastal apartment)
Light cosmetic update (paint, lighting, bathroom refresh)	from about €15,000
Comprehensive upgrade including electrical and plumbing	up to about €35,000
Tourist-ready furnishing	€4,000 to €7,500
Projects, licenses and contingency	10% to 15% of the budget

All figures come from this 2026 investment analysis. Treat them as planning ranges, not quotes. Prices vary by city, building access, age of installations and finish level, so ask for an itemized budget from at least two contractors.

Two budget lines owners forget:

Contingency. Older buildings hide wiring, plumbing and damp problems. The 10% to 15% reserve for projects, licenses and surprises is not optional.
Operating costs after the renovation. If you outsource cleaning and maintenance, expect roughly 15% to 25% of monthly revenue, per the same analysis. A beautiful flat with a thin margin is still a thin margin.

What 30,000 or 40,000 euros can realistically do

Readers often ask what a fixed sum buys. On the 70 m² benchmark above, €30,000 covers a serious refresh of kitchen, bathroom, flooring, lighting and climate control, but probably not a full rewire plus replumbing plus furnishing. With €40,000, a comprehensive upgrade and furnishing come into reach on the same size of flat. Smaller units stretch further and larger ones do not. Get a technical visit before you commit to a number.

Where to spend: guests, photos and maintenance

Holiday rental renovation is not residential renovation with nicer cushions. Residential finishes aim at decades of daily use by one household. A holiday rental needs high-impact visuals for the listing, and fixtures that survive turnover every few days.

Market analysts describe the 2026 winners as experience-led: fast internet, smart locks for self check-in, and neutral but photogenic interiors. The metric that matters is the listing’s conversion rate, meaning how many people who view it actually book. That is tied directly to how good the place looks in photos after the work.

Priorities, in order

Climate control and ventilation. Required in many regions and decisive for reviews in summer. Quiet, efficient units beat cheap noisy ones.
Bathrooms. Guests judge cleanliness here first. Walk-in showers with screens, good drainage and light, wipeable surfaces.
Kitchen. Functional rather than gourmet: a real hob, fridge with freezer, dishwasher if space allows, and enough cookware for the capacity you advertise.
Beds and sleep quality. Good mattresses and blackout shutters cost little relative to the review impact.
Connectivity and access. Fiber broadband, a Wi-Fi router in a central spot and a smart lock so you are not tied to key handovers.
Lighting and finishes for photos. Warm, layered lighting and a neutral palette photograph well and age slowly.

Choose for durability and modularity

Commercial-grade textiles and modular furniture lower long-term replacement costs, which the same analysis flags as a common pitfall for new hosts. Pick items you can replace one at a time: a single sofa cushion cover, a single chair, a single bedside lamp.

Quick wins that avoid heavy work

Not every property needs a full renovation. If the structure and installations are sound, character often comes from walls. Removable decorative panels, for example, add warmth and acoustic comfort without drilling or painting, which is handy when you want to refresh a unit between seasons. Modular PET felt wall panels that install with adhesive are one option, and they leave the wall intact if you change the look later.

Taxes and yield: run the numbers after the renovation

Renovation budgets look different once you add 2026 taxation. Tax experts warn that the main strategic error this year is ignoring tax and regulatory pressure. Projects viable in 2024 on gross revenue alone now face compressed net returns.

Income tax

According to Guía Fiscal, holiday rentals are taxed as real estate capital income if you only grant use of the property. They become economic activity if you provide hospitality services. Residents pay progressive IRPF rates between 19% and 47% on net income. Non-residents generally pay 24%, or 19% if resident in the EU or EEA, through Model 210. The residential rental reduction does not apply to holiday lets, a point many owners get wrong. The tax agency’s own page on how tourist apartment rentals are taxed is the reference to check, and a Spanish tax advisor (asesor fiscal) should confirm your case.

Renovation spending itself is not a simple deduction. Improvements are generally treated differently from repairs and maintenance, and fixed costs are apportioned by rental days. Keep every invoice in your name and ask your advisor how each item is classified.

VAT

When you provide hotel-like services such as reception, periodic cleaning and linen changes during the stay, VAT at 10% applies. Cleaning only at check-in and check-out, plus maintenance, generally does not count, per the same source. The tax agency also publishes a page on whether you must charge VAT on a tourist apartment.

The new IBI surcharge

Real Decreto-ley 29/2026, dated 6 October and published in the BOE, is the newest piece. As summarized by Economist & Jurist, municipalities in stressed residential markets can add a surcharge of up to 50% on IBI for tourist dwellings, rising to 100% for owners of two or more, and to 150% for four or more. The measure is very recent, so check how your town hall applies it and what your advisor says before you finalize a business plan. Our guide to IBI in Spain explains the base tax.

A practical yield test

Before signing the renovation contract, build a simple model:

Estimate annual gross income at a realistic occupancy. One analysis suggests holiday lets can double or triple gross monthly income versus a traditional rental, only if annual occupancy stays above about 60%.
Subtract platform fees, cleaning, management, utilities, insurance and community fees.
Subtract IBI, including a possible surcharge, and income tax.
Divide the net by your total outlay: purchase, renovation, furnishing, licenses.

If the result only works with the most optimistic inputs, the project is fragile. Compare it with a long-term rental scenario too, which we cover in long-term vs holiday rentals.

Our perspective: renovate backwards from the registration number

We work with owners and investors on the Costa del Sol and in southern Spain, many of them international and non-resident. The pattern we see most is owners who start with design inspiration and discover the legal questions later. We recommend working backwards.

Start with the end state: a registered tourist dwelling that can be listed on every platform. Work out what the registration requires, what your town allows and what your building’s owners allow. Then set the renovation scope to meet those conditions with the smallest sensible budget, and spend the rest on guest-facing quality.

We also think owners underestimate presentation. The renovation is not finished until the property is photographed well and the listing describes it honestly. That is why our holiday rental management includes a professional photo book, and why we ask for a profitability study before a renovation is quoted, not after. A renovation that raises your nightly rate by less than it costs to finance is not an improvement.

Finally, we would rather you walk away from a flat than renovate one that cannot be registered. That is a conversation we are happy to have early, and it costs far less than a failed licence.

A sensible order of work

Confirm legality. Zoning, community statutes, registration conditions in your region.
Technical visit. An architect or technical expert checks structure, installations and what the licence will require.
Define scope and budget. Itemized, with a 10% to 15% reserve.
Apply for works permits where the scope requires them, and keep proof for later.
Renovate. Prioritize installations first, then finishes.
Furnish and equip. Plan for replacement, not for one season.
Obtain registration and required certificates such as the energy certificate where applicable.
Photograph, list, and test. Fix the small things reviews reveal in the first month.

Our investor-focused piece on renovation ideas in southern Spain goes deeper into scope choices, and the investment roadmap for 2026 places the renovation inside a wider plan.

FAQ

How much does it cost to renovate an apartment for holiday rental in Spain?

For a typical 70 m² coastal apartment, the research we reviewed shows about €15,000 for a light update and up to about €35,000 for a comprehensive upgrade. Furnishing adds €4,000 to €7,500, and you should reserve 10% to 15% for projects, licenses and surprises. Get itemized quotes for your own property.

Do I need a licence before renovating a holiday rental?

You need two separate things. Works that change the structure or use usually need a municipal works licence, and tourist operation needs registration with your region. Check use compatibility with local zoning first, because that is the most common cause of refusal. Your town hall and a local architect can confirm the exact requirements.

Can I apply the residential rental tax reduction to a holiday rental?

No. As of 2026, holiday lets are excluded from the reductions that apply to permanent housing rentals, according to Guía Fiscal. Residents pay IRPF at 19% to 47% on net income, and non-residents generally 24% (19% for EU/EEA residents). A Spanish tax advisor can confirm your situation.

Is it still worth renovating for holiday rental after the 2026 changes?

It can be, but only when the numbers work with higher tax and compliance costs. Model your net yield including a possible IBI surcharge, realistic occupancy and professional management. If the project only works at peak assumptions, consider a long-term rental or a different property.
