Some states, from Florida to California, offer opportunities for low-cost beach ceremonies. Some couples rent a condo beside a beach, and some of those condos may allow you to use that space for a ceremony. Permission, however, is required. If you're getting married on a public beach or in a public park, most of the time you'll need to obtain permits, and those are relatively inexpensive but necessary. Of course, you also need an officiant and legal paperwork to make it official. But beachside and lakeside ceremonies can be budget-friendly.
