Growing fruit trees at home can be risky or undoable because of lack of space, or interfering plumbing structures that can contaminate fruit or become damaged by root growth. The solution to this might be to grow your fruit trees in very large pots instead of planting them directly in the soil, and then choosing the type of fruit tree wisely based on tree size.
Potted fruit tree ideas:
Meyer Lemon: This is the gold standard for container citrus. It stays relatively small, produces incredibly sweet-tart lemons year-round, and handles the local heat beautifully.
Kumquat: Specifically the "Meiwa" or "Nagami" varieties. They have deep taproots but adapt surprisingly well to large pots and are very wind-resistant. A kumquat is a small, olive-sized citrus fruit native to China that is unique because you eat it entirely whole—sweet peel and all—with a tart, tangy pulp inside
Dwarf Mango (e.g., 'Pickering' or 'Cogshall'): Mangoes love the coastal heat. The 'Pickering' variety is known as a "condo mango" because it naturally stays very compact and bushy, making it highly wind-resistant and perfect for a large planter.

The Calamansi, also known as the calamondin: A compact, heavy-producing hybrid citrus tree native to the Philippines and Southeast Asia. It is a cross between a mandarin orange and a kumquat, yielding small, round fruits with a tart, lime-like flavor and a sweet peel.
Barbados Cherry (Acerola): This is a sprawling, bushy tree that takes extremely well to pruning and container life. It is highly salt-tolerant and produces massive amounts of vitamin C-packed cherries.
Pineapple Guava (Feijoa): Extremely tolerant of salty coastal air and wind. It grows more like a large shrub, has beautiful edible flowers, and produces sweet, gritty fruit.
Dwarf Everbearing Mulberry: This tree loves being pruned, which makes it perfect for a pot. It grows fast, handles the humidity effortlessly, and continuously produces sweet, blackberry-like fruit.
Dwarf Cavendish Banana: While technically a giant herb rather than a tree, dwarf bananas do fantastic in large, heavy tubs. They love the humidity near the water, though you'll want to tuck them in a spot where the massive leaves are somewhat protected from the strongest canal winds so they don't shredb
