Belize lacks accessibility regulations and many buildings are on stilts or have uneven wooden steps. You won't see many ramps for wheelchair access and there are very few bathrooms designed for visitors in wheelchairs.
More difficulties for wheelchair users come from the lack of footpaths, as well as plentiful rough and sandy ground. With assistance, bus travel is feasible, but small planes and water taxis might be a problem.
Not to put too fine a point on it – Belize is a very challenging destination for visitors with limited mobility. But while Belize definitely lacks accessible travel facilities it has no shortage of extremely helpful locals who are generally more than willing to lend a hand to assist travelers with special needs in getting around.
