The Complete Grand Oaks Guide. (2026)

Executive Summary

Grand Oaks is a 524-acre mixed-use master-planned new-construction community in St. Augustine, St. Johns County, set in the World Golf Village area off I-95. Unlike a typical residential subdivision, it is planned to combine homes with on-site restaurants, shops, boutiques, and office space, a live-work-play layout, alongside an extensive amenity package and a large share of preserved natural land. It is still building out, which means buyers can get in during the community’s growth phase.

The community spans multiple home types and life stages. Its confirmed active new-construction anchor is Summer Bay at Grand Oaks, a gated 55-plus active-adult neighborhood by Pulte that is now selling, with single-family homes on 40-, 50-, and 65-foot homesites from the mid-$300,000s into the mid-$400,000s. The broader Grand Oaks community offers all-ages new homes as well, and as a phased master plan the builder roster and available neighborhoods shift over time, so current offerings are worth confirming.

Grand Oaks is zoned for the top-rated St. Johns County School District, with a 30-acre middle-school site donated to the county and elementary and middle schools planned close by. Its amenity plan is deep: a clubhouse and pool, splash park, playgrounds, sports and pickleball courts, a dog park, walking trails, and more, with roughly 30 percent of the land kept as preserve and recreation. This guide covers the neighborhoods, the builders, the homes, the amenities, the costs, and the honest trade-offs of buying new, including why you bring your own agent to the builder.

Quick Facts

Community Overview & History

A mixed-use master plan

Grand Oaks is a master-planned, mixed-use community on roughly 524 acres in the World Golf Village area of St. Augustine, in fast-growing St. Johns County. What distinguishes it from a standard subdivision is the plan to integrate homes with a town-center component: on-site restaurants, shops, boutiques, and office space, so residents can live, work, shop, and dine within the community. The design also preserves a large share of the land, with about 30 percent set aside as preserve, recreation, and open space, and it incorporates existing trees, ponds, and natural areas.

Because Grand Oaks is still building out, with the residential neighborhoods, amenities, and commercial components arriving in phases, buyers have the chance to get in during the growth phase. As the community matures and the town center fills in, that early positioning is part of the appeal, especially in a county where new amenities and schools are constantly being added to keep pace with growth.

Built for all ages, anchored by 55+

Grand Oaks is designed to serve multiple life stages. The broader community offers all-ages single-family homes, and within it sits Summer Bay at Grand Oaks, a gated 55-plus active-adult neighborhood by Pulte that is actively selling. That mix, families and active adults in one master plan with shared and dedicated amenities, gives Grand Oaks a broad appeal and a built-in sense of community, while the Summer Bay residents get their own gated, low-maintenance enclave with exclusive amenities.

Neighborhoods & Builders

Grand Oaks is a phased master plan, so the buying decision starts with which neighborhood and life stage fits, and with confirming the current active builders and inventory.

Summer Bay at Grand Oaks (Pulte 55+)

The confirmed active new-construction anchor is Summer Bay at Grand Oaks, a gated 55-plus active-adult neighborhood by Pulte, now open and selling. It offers single-family homes on 40-, 50-, and 65-foot homesites designed around conservation, lake, and park views, with open-concept floor plans and designer options. As of 2026, pricing runs from roughly $343,990, with popular models in the high-$300,000s to mid-$400,000s (for example, plans around 1,580 to 1,860 square feet). Summer Bay has its own gated entry and exclusive amenities, including a resort-style pool, pickleball and bocce courts, an outdoor firepit and fireplace, and a community garden, on top of access to the broader community.

All-ages neighborhoods

The broader Grand Oaks community also offers all-ages single-family new homes. Because it is a phased master plan in an active St. Augustine new-construction market, the specific builders and neighborhoods open at any given time change as phases release. Rather than rely on a fixed list, confirm the current active all-ages builders, available plans, and inventory at Grand Oaks before you visit, which is exactly the kind of up-to-date legwork your agent should do for you.

Quick move-in vs. to-be-built

Like most new communities, Grand Oaks carries both quick-move-in homes (already under construction or complete, faster to close, less customization) and to-be-built homes (choose the plan, lot, and finishes, more personalization but a longer timeline, typically several months). Builder incentives in 2026 have included rate buydowns and closing-cost help on select quick-move-in homes, so it pays to ask which incentives apply to which homes.

The Market & Pricing

Grand Oaks sits in a competitive, top-rated St. Johns County new-construction market, and it is positioned as a relatively accessible way into the district. The confirmed active pricing is in Summer Bay at Grand Oaks, where homes start around $343,990 and most models run from the high-$300,000s into the mid-$400,000s. The average Summer Bay home price has run in the low-to-mid $380,000s. All-ages pricing in the broader community varies by builder, plan, and phase, so confirm current numbers directly.

Several factors shape the real cost. Lot premiums for conservation, lake, and park-view homesites add to the base. Design-center upgrades move the number quickly. Builder incentives are active in the current rate environment, with rate buydowns and closing-cost contributions on select homes, so comparing homes and asking about incentives pays off. And buyers should confirm the full fee structure, the HOA dues and whether a CDD assessment applies, since a community of this scale and amenity depth may carry one.

For context, Momentum tracks the wider Jacksonville metro at a 97.98 percent sold-to-list ratio and 64 days on market for our agents, against a RealMLS market average closer to 96.73 percent and 72 days, year to date. In a new community like Grand Oaks, builder pricing, incentives, lot selection, and your representation matter more than resale comps, which is where an agent who knows the community pays off.

Who Lives Here

Grand Oaks attracts a deliberately broad mix because the master plan serves multiple life stages. Summer Bay draws active adults 55 and over who want a gated, low-maintenance, amenity-rich enclave near St. Augustine. The all-ages neighborhoods draw families and move-up buyers attracted by the top St. Johns schools, the planned town center, and the live-work-play convenience. And the mixed-use, amenity-heavy design appeals to buyers who want walkability to shops and dining as the community fills in.

Many buyers are relocating within the metro to get into the St. Johns district, or moving from out of state drawn by the St. Augustine lifestyle, the value relative to coastal communities, and the active-adult option. The combination of a 55-plus neighborhood, all-ages homes, and a future town center gives Grand Oaks an unusually wide demographic for a single community, which residents tend to see as a strength as the neighborhood matures.

Schools

Grand Oaks is served by the top-rated St. Johns County School District, consistently ranked the number one district in Florida, which is a primary draw. The master plan was designed with schools in mind: a 30-acre site was donated to St. Johns County for a middle school, and the community is planned so that elementary and middle schools are close by, a meaningful convenience for families.

Because the World Golf Village area is growing quickly and the county is constantly opening new schools and adjusting boundaries, attendance zones can shift as the community and surrounding area build out, and any school references should be treated as estimates. The Summer Bay neighborhood is age-restricted (55-plus), so school zoning matters mainly for the all-ages homes. Buyers with school-age children should confirm the exact current zoned schools for a specific Grand Oaks address directly with St. Johns County Public Schools before relying on any assignment.

Amenities & Lifestyle

Amenities are a centerpiece of Grand Oaks, with a deep package planned and built across the community plus dedicated amenities for the 55-plus neighborhood.

Community amenities

The Grand Oaks amenity plan is extensive: a clubhouse and amenity center with a pool and pool house, a splash park, playgrounds, a party pavilion, sports courts, tennis and pickleball courts, a dog park, walking paths, and recreational features such as a rose garden, croquet lawn, lawn bowling area, and a sports field for soccer and football. Roughly 30 percent of the community is kept as preserve, recreation, and open space, woven through with natural areas, ponds, and existing trees.

Summer Bay 55+ amenities

Summer Bay at Grand Oaks has its own gated, exclusive amenities for the active-adult lifestyle, including a resort-style pool, pickleball and bocce ball courts, an outdoor firepit and fireplace, and a community garden, designed to keep residents social and active. Summer Bay residents get this dedicated package on top of the broader Grand Oaks community amenities.

The mixed-use lifestyle

The planned town-center component, on-site restaurants, shops, boutiques, and office space, is what sets Grand Oaks apart over the long term. As the commercial element fills in, residents will be able to walk or take a short drive to dining, shopping, and services without leaving the community, a live-work-play convenience that is still relatively rare in the area. For buyers willing to grow with the community, that future walkability is a meaningful draw.

HOA & CDD

Grand Oaks’ cost structure should be mapped carefully, since the all-in monthly is what matters, not the base price.

Confirm whether a CDD applies. Many large, amenity-rich St. Johns County master plans use a Community Development District to finance and maintain infrastructure and amenities, with the assessment collected on the annual property tax bill. Given Grand Oaks’ scale and amenity depth, buyers should confirm directly with the builder whether a CDD assessment applies to a specific home and lot, and at what amount, before writing a contract.

There are HOA dues. As a master-planned community with shared amenities, Grand Oaks carries HOA dues, and the gated Summer Bay neighborhood has its own association arrangement for its exclusive amenities. Confirm the specific dues for the neighborhood you are considering.

Factor lot premiums and upgrades. Conservation, lake, and park-view lots carry premiums, and design-center upgrades add to the price. These are one-time costs, but they change the all-in number meaningfully.

Model the true all-in monthly. Between the mortgage, any CDD assessment, HOA dues, and the way new-build property taxes often reset upward after the first year, the all-in monthly cost can run above the base price. A good agent will help you build the real number and compare homes and incentives before you commit.

Commute Analysis

Grand Oaks’ World Golf Village location off I-95 balances a quieter St. Augustine setting with reasonable access to Jacksonville and the coast.

Grand Oaks sits near the I-95 interchange in the World Golf Village area, giving a quick commute north toward Jacksonville’s Southside (about 30 to 35 minutes) or south to historic downtown St. Augustine (about 20 to 25 minutes), with the St. Augustine Premium Outlets and World Golf Village shopping minutes away. For buyers who work on the Southside, in St. Augustine, or remotely, and who want top schools and an active-adult or family lifestyle at a manageable price, the location works well. The trade-offs are the 30-plus-minute drive to the beaches and I-95 commuter traffic at peak hours. As the on-site town center fills in, more daily errands will be doable without leaving the community.

Shopping & Dining

Grand Oaks is close to solid shopping and dining today and is planned to add its own on-site town center over time. The World Golf Village area nearby offers restaurants, shops, golf, and entertainment, and the St. Augustine Premium Outlets (about 10 to 15 minutes away) provide major outlet shopping, with grocery stores and everyday services along the corridor.

Historic downtown St. Augustine, about 20 to 25 minutes south, adds its renowned dining, boutiques, and historic charm, and the St. Johns Town Center is reachable to the north. The long-term differentiator is Grand Oaks’ planned on-site restaurants, shops, and boutiques, which, as they fill in, will give residents walkable dining and retail within the community. For a community in the growing World Golf Village area, the current access plus the future town center make for a strong shopping and dining outlook.

Pros and Cons

Grand Oaks vs. Comparable Communities

Most buyers weighing Grand Oaks are comparing it with the other St. Augustine and St. Johns master plans. Here is the honest shorthand.

Hidden Things Buyers Should Know

A few things that consistently come up once buyers get serious about a phased, mixed-use community like Grand Oaks.

You are buying into a future, not just a house

The mixed-use town center, on-site restaurants, shops, and offices, is part of the long-term value, but it arrives in phases. Ask where the commercial component and remaining amenities stand and what the timeline is, so your expectations match reality on the day you move in.

The 55+ side is the confirmed active anchor

Summer Bay at Grand Oaks by Pulte is the clearest active new-construction opportunity here, gated, amenity-rich, and now selling from the mid-$300,000s. If you are 55 or over and want a low-maintenance home in a top school county near St. Augustine, it belongs on your list, and the broader Grand Oaks amenities come with it.

Confirm the fees before you fall in love

A community this size and amenity-rich may carry a CDD on top of HOA dues. Confirm whether a CDD applies to the specific home and lot, the HOA dues, and the post-first-year tax reset, so the true monthly is clear before you commit.

Verify the current all-ages builders

Because Grand Oaks releases in phases, the all-ages builders and neighborhoods open at any moment change. Do not assume a fixed roster, confirm who is building, what plans are available, and which incentives apply right now. An agent who tracks the community will have the current picture.
