Converting a Tennis Court to Padel: Cost & ROI 2026

Converting a tennis court to padel costs €30,500 to €74,000 per court in 2026, plus €5,000–10,000 for planning and permits (Sportstättenrechner, 2026). Actual build time is four to eight weeks. From the first board meeting to the first rally, budget three to six months — most of that is the permit process, not construction.

The timing is no accident. Germany now has 1,924 padel courts across 605 facilities (Padel-Atlas, July 2026), around 350,000 people play regularly, and the court count has grown by an average of 81% per year since 2021. At the same time, the German Tennis Federation reports 1,517,087 members — its fifth consecutive growth year. Padel does not cannibalise tennis; it fills the empty slots in your booking calendar.

What does it cost to convert a tennis court to padel?

The range is wide because it depends on the base surface, the fittings, and the lighting. These line items make up a single court (Sportstättenrechner, 2026):

• Steel-and-glass structure: €15,600–27,600 — the largest single item, and what decides durability and looks
• Artificial turf surface: €3,800–9,400 — sand infill included
• LED floodlighting: €1,800–6,900 — essential if you want to sell evening slots (and you do)
• Accessories: €1,200–6,400 — doors, nets, scoreboards, fencing panels
• Starter kit: €840–1,800 — rental rackets and balls for beginners and taster sessions
• Planning and permits: €5,000–10,000 — building application, structural engineering, acoustic report

The real saving in a conversion is the base: on clay and hard courts you can usually build on the existing sub-base, which removes most of the foundation work. Build a court from scratch on open ground and the full outdoor project including foundation quickly reaches €60,000–100,000 per court.

Indoor is a different calculation. A court inside an existing hall runs €23,000–58,000, while a new padel hall with four courts costs €320,000–825,000 net. For tennis clubs sitting on an underused clay court, the outdoor conversion is almost always the cheaper way in.

How many padel courts fit on one tennis court?

A padel court measures 20 × 10 metres; a tennis court with its run-off zones covers roughly 36 × 18 metres. Depending on layout and clearance requirements, that yields two to three full-size padel courts.

But the economic lever is not floor area — it is heads per hour:

• Tennis: 2 players in singles, 4 in doubles — per court, per hour
• Padel: always 4 players per court, so 8–12 people on the same footprint
• Slot length: padel is usually booked in 60- or 90-minute slots — more turnover per day than tennis block bookings
• Barrier to entry: padel is playable much sooner, which makes taster sessions, corporate events, and member recruitment far easier

That is exactly why padel works as a membership engine: the core audience is active adults aged 25 to 55, often with a tennis, squash, or fitness background — precisely the group many clubs have been trying to win back for years.

Does the conversion pay off? A worked example

Plan around realistic occupancy: 40–60% average daily utilisation is considered stable in the industry. The example below is a rough orientation for two outdoor courts on a converted clay court — not a forecast for your site.

1. Investment: 2 courts at roughly €45,000 each + €8,000 planning = about €98,000
2. Hourly price: €20–35 per court outdoor; €28 average used here
3. Occupancy: 5 booked hours per court per day across 240 playing days (outdoor season plus mild months)
4. Gross revenue: 2 × 5 × €28 × 240 = about €67,200 per year
5. Operating costs: 25–30% for electricity, cleaning, maintenance, insurance, and the booking system
6. Surplus before depreciation: about €47,000 per year → payback in roughly 2–3 years

Run it more cautiously, at just 3 booked hours per court per day, and about €29,000 remains — the investment is then back in about 3.5 years. Conservative industry figures cite 6–10 years, because they price in a new foundation, financing costs, and weaker locations. Established operators with four courts and seven booked hours a day reach €220,000–300,000 in annual revenue.

Two factors decide where you land in that range: visibility and bookability. Courts handed out only by noticeboard and a phone list rarely clear three booked hours a day. Get online-bookable and you also sell the fringe morning slots. On RacketTogether you can list your facility for free and make courts and courses bookable online.

Permits and noise: the underrated stumbling block

Padel is louder than tennis. The ball strikes glass and walls, four people play at once, the shot frequency is higher — and unlike tennis, players talk loudly throughout. This is where projects fail, not on budget.

The governing rule is the German Sports Facility Noise Protection Ordinance (18. BImSchV). It sets immission limits by zone and time of day — in general residential areas 55 dB(A) during the day, 50 dB(A) in quiet periods, and 40 dB(A) at night. Neighbours can enforce these limits in court, and administrative courts have overturned permits for breaching the duty of consideration more than once.

What helps in practice:

• Acoustic report first, quote second: an acoustics firm calculates the height, length, and material of the required barrier — and you need that report for the building application anyway
• Check the position within your site: every metre of distance from housing and every existing building that screens the court lowers the immission values
• Cap operating hours yourself: self-imposed end times (e.g. 10 pm) and quiet-period rules are a strong argument in the permit process
• Involve neighbours early: an information evening before the application costs nothing and heads off objections that cost months
• Clarify change of use: converting an existing court is not automatically permit-free — confirm with the local building authority up front

Funding: what grants clubs can get

As a registered club, you rarely pay for the conversion alone. Grant rates from the regional sports federations (Landessportbünde) vary sharply by state:

• Thuringia: up to 60% co-financing from the LSB sports-facility grant
• Lower Saxony: a fixed grant rate of 40%
• Hesse: rate raised from 20% to 35%
• Municipal: cities and districts often add funding, sometimes via sports-facility lump sums
• Federation support: state tennis associations advise on planning and financing — start with the DTB club guidance on planning and financing

One rule on sequence matters: grant applications almost always have to be filed before you award the contract. Build first and apply later, and you lose the grant.

From clay court to padel court in 7 steps

1. Pick the court: the least-used clay or hard court with the greatest distance from housing
2. Test demand: a member survey plus a look at padel supply within 15 km — no courts there means that is your catchment area
3. Commission the acoustic report: before any purchase decision; the cost sits inside the €5,000–10,000 planning budget
4. File building and grant applications: in parallel, but the grant application must come before the contract award
5. Get quotes: at least three suppliers, compared on identical specs (glass thickness, surface, lighting level)
6. Build: 4–8 weeks of actual construction for two outdoor courts
7. Make it bookable: online booking, prices, and taster sessions from day one — empty courts pay back nothing

Step seven is the one most clubs underrate. Padel newcomers search online for a free court in their city, not for a club phone number. Make your facility visible in the facility search on RacketTogether and those are exactly the players who find you — including the ones without a membership.

Frequently asked questions about converting a tennis court to padel

What does a padel court cost in total?

An outdoor padel court costs €30,500–74,000, plus €5,000–10,000 for planning and permits. When you build over an existing clay or hard court, the foundation work drops out and total costs land at the lower end. A full new build including foundation runs €60,000–100,000 per court, and an indoor court inside an existing hall €23,000–58,000.

When does a padel court pay for itself?

At healthy occupancy the conversion pays back in 3–5 years, or 6–10 years on conservative numbers. Occupancy is the deciding factor: two courts with five booked hours a day at €28 generate about €67,200 in annual revenue. At just three booked hours it is about €40,000, and the payback period stretches accordingly.

Does the conversion need a building permit?

Usually yes. A padel court is both a structure and a sports facility, so a building application and a noise-protection assessment under the 18. BImSchV are required. Even when a tennis court is already approved, the conversion often counts as a change of use in planning law. Clarify this with the local building authority before you request quotes.

Is there funding for padel courts?

Yes, through the regional sports federations. Rates range from 35% in Hesse and 40% in Lower Saxony to 60% in Thuringia, and municipalities sometimes add more. Padel is generally treated like any regular sports-facility construction. The application must be filed before the contract is awarded — otherwise the entitlement lapses.

Outdoor or indoor — which makes more sense for a tennis club?

For most clubs the outdoor conversion on an existing clay court is the more economical entry: lower investment, no foundation work, shorter build time. Indoor courts command higher prices at €30–50 per hour and are bookable year-round, but they need a hall — a new build with four courts costs €320,000–825,000. A common strategy: start outdoor, measure demand, then decide on a roof.

The German padel market is growing faster than facilities can open — 1,924 courts for around 350,000 players means booking calendars stay full at well-located sites. If a clay court sits half-empty at your club, converting it is the most realistic way to get three to four times the players out of the same footprint.
