Living near Geist Reservoir means your backyard is more than just a yard — it is part of what drew you to the area in the first place. Whether you have a direct waterfront lot, a view through the trees, or simply enjoy the lifestyle that comes with being minutes from the water, a well-built deck can make the most of that setting.
But building a deck at Geist is not as simple as picking a material and calling a contractor. The reservoir area spans three counties, four municipalities, and dozens of HOA communities — each with its own rules. This guide helps you understand what to consider before breaking ground.
Why Geist Is Different: The Jurisdiction Map
Geist is not a city or a town. It is a community defined by the reservoir, and the approximately 2,200-plus homes that surround it fall into several different jurisdictions. Where your property sits determines who issues your building permit, what zoning rules apply, and what inspections are required.
| If Your Geist-Area Property Is In… | Your Building Permit Comes From… |
| City of Fishers (Hamilton County) | City of Fishers Building & Zoning — (317) 595-3160 |
| City of Lawrence (Marion County) | Lawrence Dept. of Public Works — (317) 545-8787 |
| Indianapolis / Marion County (Lawrence Twp.) | Indy BNS — (317) 327-8700 |
| Town of McCordsville (Hancock County) | McCordsville Planning & Building — (317) 335-3604 |
| Unincorporated Hancock County | Hancock Co. Planning & Building — (317) 477-1133 |
We have published detailed permit guides for several of these offices. If your home is on the Hancock County side, our guide on obtaining deck approval through the Hancock County building office is a helpful starting point.
HOA Approval: The Step Most Homeowners Underestimate
The majority of Geist-area homes are governed by a homeowners association. Many of these HOAs have architectural review committees (ARCs) that must approve any exterior change — including a new deck, a deck expansion, a screened porch conversion, or even a material change on an existing deck.
The largest association in the area, the Geist Harbours Property Owners Association (GHPOA), encompasses twelve individual communities and roughly 2,380 lots across three counties and four cities. Other prominent communities with their own HOA governance include The Springs of Cambridge, WatersEdge, Geist Overlook, Admirals Landing, and many more.
Each HOA has its own covenants, and the specifics vary. But here is what you should generally expect:
- Submit plans to your ARC before applying for a building permit. Most HOAs want to review and approve the design, materials, and placement before you go to the city or county.
- Setback and lot coverage rules may be stricter than the municipal code. Your HOA covenants can impose tighter restrictions than the local zoning ordinance requires.
- Material and color restrictions are common. Many Geist communities require specific decking materials, railing styles, or color palettes to maintain a consistent look.
- Waterfront lots may have additional restrictions. If your property borders the reservoir, there may be rules governing how close structures can be to the water’s edge, dock connections, and shoreline grading.
Bottom line: Get your HOA approval in writing before you file a permit application. Doing it in the wrong order can lead to costly redesigns, construction delays, or worse.
What Makes Waterfront Deck Projects Unique
Decks near the reservoir face conditions that typical suburban lots do not. If you are on or near the water, keep the following in mind:
- Soil and grading. Lots that slope toward the reservoir may require engineered footings or retaining walls to support a deck properly.
- Moisture exposure. Decking materials on waterfront properties are exposed to more humidity and direct water contact. Composite and PVC decking tend to hold up better in these conditions.
- View preservation. If your deck design includes a pergola, screened enclosure, or elevated structure, check whether it might obstruct sightlines from neighboring properties.
- Drainage and runoff. Geist Reservoir is managed by Citizens Energy Group as a public water supply. Large impervious surfaces can affect stormwater runoff patterns, which may require additional drainage review.
Popular Deck Features for the Geist Lifestyle
The Geist area is a premium outdoor living market. Many homeowners here go beyond a basic deck platform and invest in features that complement the waterfront setting:
- Multi-level decks that follow the natural slope of a lot down toward the water
- Screened porches for bug-free evenings during Indiana’s humid summers
- Covered outdoor kitchens with built-in grills, sinks, and countertops
- Cable railing systems that maintain an open view of the reservoir
- Integrated lighting — post cap lights, step lights, and recessed rail lighting for evening use
- Dock-connected walkways on waterfront lots with private dock access
Keep in mind that some of these features — particularly screened porches, covered kitchens, and any structure with a roof — may require additional permits beyond a standard deck permit.
Material Considerations for Central Indiana’s Climate
Central Indiana sees hot, humid summers and freeze-thaw cycles in winter. Near the reservoir, moisture levels stay higher year-round.
| Material | Pros | Cons |
| Pressure-treated lumber | Lowest upfront cost; widely available; easy to work with | Requires regular sealing; can warp, crack, and splinter |
| Composite decking | Low maintenance; resists rot and insects; wide color selection | Higher initial cost; can get hot underfoot in direct sun |
| PVC decking | Best moisture resistance; does not absorb water; lightweight | Highest cost; can feel less natural underfoot |
| Hardwood (ipe, tigerwood) | Beautiful natural look; extremely durable; long lifespan | Very expensive; difficult to cut and fasten |
For reservoir-adjacent properties where moisture is constant, composite or PVC decking is often the better long-term investment. If you want to explore the durability side further, our article on how Indiana’s freeze-thaw cycles affect deck structures in Carmel covers this in more detail.
The Permit and HOA Checklist for Geist Homeowners
| Step | Details |
| 1. Identify your jurisdiction | Determine whether you are in Fishers, Lawrence, Indianapolis, McCordsville, or unincorporated county |
| 2. Review your HOA covenants | Check for ARC requirements, material restrictions, setback rules, waterfront provisions |

| 7. Pass inspections | Footing and final inspections at minimum; additional for covered/enclosed structures |
One More Thing: Citizens Energy Group and the Reservoir
Geist Reservoir is owned and managed by Citizens Energy Group as part of Indianapolis’s water supply. If your deck project involves any work near the shoreline — grading, retaining walls, dock modifications, or construction that could affect runoff into the reservoir — you may need to coordinate with Citizens Energy in addition to your local building department. Your HOA can usually tell you whether this applies to your lot.
