Al Wadi Al Kabir Industrial City, Muscat: Workshops, Rules & Setup

Al Wadi Al Kabir Industrial City is a long-established industrial and workshop district in the Wilayat of Muttrah, central Muscat. Madayn has managed it since 2022. It covers about 2.15 million m2 and hosts more than 2,670 businesses, mostly garages, workshops, warehouses and wholesale traders. It suits service and trade businesses that need to be in the capital. It is not a greenfield site for new factories.

Where is Al Wadi Al Kabir Industrial City?

Wadi Al Kabir lies between Ruwi and Muttrah, in the middle of Muscat's commercial core. Customers, government offices and banks are minutes away, and Muscat International Airport is reachable by expressway. Most commercial sea cargo for Muscat now moves through Sohar and other ports, since Port Sultan Qaboos in Muttrah was converted mainly to tourism use.

The location is the main selling point: no other Madayn estate is this close to Muscat's residential and business districts.

What changed when Madayn took over?

• 2022: Madayn completed the groundwork and began serving investors in the city, covering industrial blocks 142, 144, 146, 154 and 158. It set up a Masar service centre in the administration building near Nesto Hypermarket and moved transactions and payments online.
• Rehabilitation: Madayn tendered consultancy work to upgrade infrastructure, prepare a detailed masterplan and fix water, sewage and road networks. Road repairs and campaigns to remove abandoned vehicles have followed.
• December 2025: the OPAZ Board approved a regulatory framework for the city to improve infrastructure and services.

For existing tenants, this means more formal permits, inspections and service charges than under the previous arrangement. Check that your premises and activity comply.

What businesses fit Wadi Al Kabir?

Madayn lists:

• warehouses and storage, including chemical, oil and wood stores
• industrial workshops and small factories
• vehicle repair, maintenance and spare parts
• commercial outlets, offices, and wholesale and retail stores

It suits garages, fabrication shops, distributors and trade counters. Activities with heavy emissions, large land needs or hazardous processes are better placed in Rusayl Industrial City or Samail Industrial City.

Ownership and incentives

Up to 100% foreign ownership is possible through an Omani company registered under the Foreign Capital Investment Law, subject to the activity rules. Madayn leases carry the usual rights to sublease and transfer with approval. Because this is an urban service district, the main benefit is location rather than land incentives. There is no published rent-free period.

How to set up or take over premises in Wadi Al Kabir

1. Register the company on the Oman Business Platform with the correct workshop, trade or warehousing activity (guide).
2. Find premises. Most entries are a transfer or sublease of an existing unit, which needs Madayn's approval. New plots are occasionally offered.
3. Apply to Madayn through the e-Masar portal or the on-site Masar centre to register the lease or transfer.
4. Sign or transfer the lease agreement and settle any outstanding charges on the unit.
5. Get permits: Madayn permits for any building changes, Civil Defence approval, and environmental approval where relevant.
6. Hire staff and apply for work permits.

Documents usually required

• Commercial Registration and company documents
• Owner and signatory passport or ID copies
• The existing lease and the transferor's consent (for a takeover)
• Unit layout and a description of the activity
• Power of attorney if an agent applies for you

Cost components

Madayn does not publish a standard rent for Wadi Al Kabir. Expect:

• rent according to Madayn's rate for the plot and use
• the common area maintenance charge
• Madayn transaction and permit fees
• any key money or premium agreed privately with an outgoing tenant
• utilities, registration, chamber and labour costs

Before paying an outgoing tenant, confirm with Madayn that the unit has no arrears or violations.

Timelines

Company registration takes days. A lease transfer through Madayn usually takes days to a few weeks, depending on approvals. Fit-out of an existing unit is generally quick compared with building on a greenfield plot.

Pros and limitations

Nearby alternatives

• Rusayl Industrial City: planned plots for manufacturing near the airport.
• Knowledge Oasis Muscat: for tech and office-based companies.
• Muscat International Airport Free Zone: for air-cargo trading.
• Mainland company registration: for shops and offices outside industrial estates.

How Oman Register helps

Oman Register registers the right activity and checks the unit's status with Madayn before you sign. We handle the lease transfer, permits, work permits and visas, which matters in an area where many premises change hands privately.
