Custom Home New Construction in St. Johns County & Jacksonville
Integrity Construction Co. builds custom homes on your lot in St. Johns County and Jacksonville — managing permits, trades, and every phase of construction from foundation to final walkthrough — with a Florida-licensed residential contractor, a fixed price, and an owner on site every active day.
Building a custom home is the most significant project most people will ever undertake. The right general contractor makes it the experience it should be: a process you understand at every step, a price that holds, a home built the way it was designed, and a builder who is present and accountable throughout. The wrong one makes it a years-long ordeal of unanswered calls, unexpected costs, and finishes that don't match the plans you approved.
Integrity Construction Co. is a Florida Certified Residential Contractor (CRC1334844), built by people who care. We manage the full construction process on your lot, from permit application through certificate of occupancy: site work coordination, foundation, framing, mechanical rough-ins, insulation, drywall, finish carpentry, cabinetry, tile, flooring, exterior finishes, and landscaping coordination. Every trade that works on your home is a licensed specialist who does that one craft.
An owner is on your jobsite every active day. Not a project manager who was hired after you signed. Felix or Dmitry — the principals of this company, with the license your permit is pulled under — is physically present every day construction is happening. That level of accountability is genuinely rare in new construction, and it produces a different result.
Who We Build For
Most of our custom-home work falls into a few clear buckets. A tear-down and rebuild — sometimes after a fire or another major loss, where you want to rebuild on a lot you already own and love. A build on an infill lot somewhere in the county that isn't tied to a single developer's builder program. And homes in areas like Palencia where you're free to bring your own general contractor rather than being routed through a builder the developer locked in.
It's worth being upfront about one thing: some of St. Johns County's most tightly controlled master-planned communities require you to use the builders the developer has approved — you can't bring an outside GC. If that's where you're building, your new home runs through their builder, not us. Where you have the freedom to choose your own contractor, that's where we come in.
What a Custom GC Does — and Doesn't Do
As your general contractor, we manage the construction of your home from your plans and specifications. You bring the lot (or we can assist with lot identification in St. Johns County), the architect or designer's plans, and your vision for finishes. We take that package and build it — coordinating every licensed trade, sequencing the work correctly, maintaining the schedule, and keeping the cost within the agreed scope.
We do not design the home from scratch — that is an architect's scope. But we collaborate closely with your design professional to ensure the plans are buildable within your budget before you're fully committed to a set of drawings. A common and expensive mistake in custom home building is to finalize an architectural plan without a GC's input on constructability and cost, only to discover during bidding that the as-drawn design costs significantly more than the budget. We get involved early in the process to prevent that.
The Florida Build Environment — What You Need to Know
Building in Florida — specifically in St. Johns County and Duval County — involves regulatory and environmental considerations that are different from most other parts of the country. Hurricane wind-load requirements in this coastal market are significant: windows, doors, and roofing must meet Florida Building Code wind-speed requirements for the specific zone, and impact-rated products are typically required throughout. This affects your product selection, your framing design, and your budget — and it's something we factor in from the design consultation, not discover during permit review.
Florida's humidity and moisture environment also changes how certain assemblies are built. Spray foam insulation in the attic (closed-cell or open-cell depending on the application) performs meaningfully better than blown-in fiberglass in a humid coastal climate — it seals the thermal envelope more completely and reduces the moisture load on the HVAC system. We can walk you through the options and their long-term cost implications.
Soil conditions in St. Johns County vary significantly by parcel, and some areas require engineered foundation solutions — pile systems, compacted fill, stem wall configurations. Your civil engineer or structural engineer will assess the specific site. We coordinate with that work and ensure the foundation is built to spec before framing begins.
Permitting and Architectural Review in St. Johns County
New construction in St. Johns County requires a comprehensive permit package: site plan, architectural drawings, structural engineering, MEP (mechanical, electrical, plumbing) drawings, and energy calculations. The permit process through the St. Johns County Building Department is thorough — plan review, inspections at each phase, and a final certificate of occupancy before you can occupy the home.
We manage the full permit application and all inspections. For homes in a community with an HOA or ARB (Architectural Review Board), there is also a review process that must be completed before permits are pulled. We prepare and submit the ARB package. These processes have real timelines, and we account for them in the overall project schedule from day one.
Fixed Price or Cost-Plus — Matched to Your Project
For a custom home built from a complete, finalized set of plans and selections, we quote an all-in fixed price — the number that holds. But new construction is also the kind of project where scope can genuinely evolve, especially on a complex custom design or a rebuild where conditions emerge as you go. Forcing a fixed price onto a fluid scope just means padding the number to cover the unknowns.
So for those projects we also offer Cost-Plus pricing: we set a fixed percentage for our services, show you every single invoice — materials, subcontractors, all of it — and add our percentage on top. Fully itemized, fully transparent, nothing marked up in the dark. We'll tell you honestly which structure fits your build.
Premium Finishes — Where the Value Lives
The structural and systems components of a custom home — framing, MEP, insulation, roofing — represent roughly half the cost of construction. The other half, and the part that determines whether the home feels extraordinary or merely acceptable, is finishes: the cabinetry, the stone work, the tile, the flooring, the millwork, the hardware, the fixtures. This is where our trade relationships produce results that a production builder cannot replicate.
Our custom cabinetry is built by the same dedicated cabinet shops that build our remodel work — not production-line boxes. The tile and stone work is installed by the same specialists who set marble in our highest-end bathroom remodels. The finish carpenter who does your millwork, built-ins, and trim package is a craftsman, not a general laborer. The finishes in a home we build hold up to close inspection because they are built by people who do one thing at a high level.
We work through a detailed selections process — materials, finishes, hardware, fixtures — before any material is ordered. Our allowances reflect real, current pricing for the level you've chosen, not a fiction priced at costs from years ago. If your selections come in under the allowance, the price comes down and the savings are yours.
The Build Process — From Ground Break to Move-In
Once your permit is approved and any architectural-review clearance is in hand, the sequence is: site preparation and foundation, framing, roof sheathing and waterproofing, window and door installation, MEP rough-in, insulation, drywall, paint prime, interior doors and trim, cabinetry installation, countertop template and installation, tile, flooring, finish plumbing and electrical, exterior finishes, landscaping coordination, and final inspections.
At each phase, we have a licensed inspector review the work before proceeding to the next phase — this is required by code and enforced by our process regardless. We never conceal work before it's been inspected.
An owner is present every active day. Progress is visible and reportable. You are never wondering what happened on your jobsite while you were at work.
At completion, we do a formal walkthrough — you with us — with a documented punch list. Final payment is due when the punch list is closed and you accept the home. The 12-month warranty on all materials and labor we provide and install begins at that date.
Realistic Timelines for Custom Homes in Florida
Total timeline from signed contract to certificate of occupancy on a custom home in St. Johns County is typically 12–18 months. The variables: plan complexity, the HOA/ARB review timeline for your specific community, county permit review time, and lead times on custom components (cabinetry, specialty windows, custom doors, stone). We give you a realistic schedule in the proposal — not an optimistic one designed to get the contract signed.
The front end of the project — design finalization, permitting, and material ordering — is where most custom home timelines slip. We push hard on this phase, front-load selections, and track long-lead items from day one.
The Way We Quote
Honest allowances — and the savings are yours
We don't quote bare builder-grade finishes and then turn every showroom selection into an upcharge. We quote middle-of-the-road finishes as your baseline. Choose upgrades and the price goes up; choose less expensive options and the price goes down — and we don't keep the difference. See how we quote →
Questions
New Construction — common questions
Do I need my own architect before coming to you?
It helps to have architectural plans or at least a serious concept, but you don't need finished construction documents on day one. We can recommend licensed architects and designers in the St. Johns County market who work well in the custom home process. We prefer to be involved before drawings are finalized so we can provide input on constructability and cost — preventing the common situation where beautiful plans get priced and come in 30% over budget.
What is your license, and why does it matter for new construction?
Felix Reznik holds Florida Certified Residential Contractor license CRC1334844. This is the license class required to permit and build a new home in Florida as the general contractor of record. It means the permit is pulled under a licensed contractor who is accountable to the Florida DBPR, not a handyman or an unlicensed builder working through a workaround. We are also fully insured, and certificates are available on request.
What happens if something in the plans can't be built as drawn?
We identify constructability issues during the pre-construction review — before you're permitted and before ground is broken. If something surfaces during construction that requires a field change, we document it, discuss it with you and your architect, and proceed with your approval. Changes to the scope at your direction result in a written change order. Changes required because of a build error or something we missed that wasn't flagged come out of our margin.
Do you build on any lot in St. Johns or Duval County?
We build on lots throughout St. Johns and Duval counties where you're free to choose your own general contractor — including infill lots, tear-down-and-rebuild sites, and communities like Palencia. (Some developer-controlled master-planned communities require their own approved builders.) Lot selection has real implications for the build — setbacks, soil conditions, community restrictions, flood zone designation, tree preservation requirements — and we can walk through a lot assessment with you before you commit to a parcel.
