Sometimes. It is the most commonly refused request in this category, the answer varies by property and by municipality, and it is almost always discovered too late. Ask before you fall in love with a venue, and get the answer in writing rather than over the phone.
It is rarely about the ceremony. It is fire code, insurance and the physical construction of the venue. A thatched palapa roof, a wooden deck, an indoor ballroom with sprinklers and a smoke detection system, and an open beach are four completely different risk profiles, and a resort that permits a contained agni on the sand may prohibit it entirely twenty metres away under a structure.
The municipality matters too. Some jurisdictions require a permit for open flame at a commercial event regardless of the property's own view, and that permit takes time.
There are workable alternatives, and it is much better to choose one deliberately months out than to be told on the day. A flameless agni using LED and fabric is widely used and photographs convincingly. Some families hold a brief contained agni outdoors immediately before moving indoors for the remainder of the ceremony. Others move the whole ceremony to the venue that permits it, even if it was not the first choice aesthetically.
Which of those is acceptable is a conversation for your family and your Pandit Ji, not for us or the resort. Our job is to get you a definitive answer early enough that the conversation can happen calmly.
“For a Hindu wedding ceremony at [named venue] on [date], will the property permit a contained sacred fire in a kund, with an extinguisher and staff present, for approximately [duration]? If yes, please confirm in the contract. If a municipal permit is required, who obtains it and by when?” Vague questions get vague answers.
