Mariah Bay

An established, rolling-hills Heath neighborhood on the Lake Ray Hubbard side of town

Mariah Bay is a smaller, established Heath neighborhood on the southern, Lake Ray Hubbard side of town, with roughly 83 lots. Most of its homes were built from the mid-1980s through the 1990s, and many now sit on generous lots with mature trees and landscaping that give the streets privacy and shade. It trades the resort amenities of Heath's newer master-planned communities for lower entry pricing, larger established lots, and a quiet, settled character - while keeping the same Rockwall ISD schools and the town's lakeside setting a short drive away.

Mariah Bay: Frequently Asked Questions

Is Mariah Bay in Heath a lakefront neighborhood?
Mariah Bay sits on the southern, Lake Ray Hubbard side of Heath, but it is an established inland-style subdivision rather than a row of true waterfront estates - most homes are near the lake and the town's rolling hills rather than directly on the water. If direct lakefront with a dock and sea wall is your goal, focus on Heath's peninsula estates or the lakeside sections of Heath Golf & Yacht Club, and ask which specific Mariah Bay homes, if any, sit closest to the water.
How much do homes in Mariah Bay, Heath cost?
Mariah Bay is one of Heath's more attainable established neighborhoods, with homes running roughly from the $330Ks into the mid-$500Ks depending on size, updates, and lot. Homes here range widely in square footage on generous lots, and because it is a small subdivision, inventory is limited and turns over slowly. Ask for current comps with an as-of month before setting expectations, since a handful of sales can move the range.
What school district is Mariah Bay in?
Mariah Bay is in Rockwall ISD, with older students generally attending Maurine Cain Middle School and Rockwall-Heath High School. The elementary campus depends on the exact attendance zone, which Rockwall ISD draws by area rather than by Heath's town limits, so a Heath address does not automatically fix a specific elementary. Confirm the current elementary and middle assignment with the district for the specific home before you offer.
