Custom Home Building, Answered

There is no honest single number, because the lot changes the answer as much as the house does. Two identical floor plans can differ substantially in total cost depending on site work: how much fill and grading the lot needs, whether water and sewer are at the road or you need a well and septic, what your FEMA flood zone requires for finished floor elevation, and how far power has to run. On the house side, the drivers are square footage, roof complexity, ceiling heights, window and door count, and the finish level in kitchens and baths. The only way to get a number you can rely on is to price a specific plan against a specific lot. We'll walk your property and give you that, at no cost and with no obligation.

No, and there's a good argument for talking to a builder first. A lot's asking price tells you almost nothing about what it will cost to build on. Drainage problems, a missing sewer connection, a protected tree in the wrong place, or a flood zone designation can each add meaningful cost to an otherwise cheap parcel. We regularly walk listings with clients who haven't bought anything yet and give a straight read on what each one would really cost to build on. That's information a listing agent generally can't provide. If you already own your lot, we'll start there instead and work the plan around what the site allows.

A build-on-your-lot builder constructs a home on land you own or are buying, rather than selling you a house inside their own subdivision. The practical difference is that the site comes first and the home is designed to suit it, instead of a fixed plan being dropped onto a developer's lot. It usually means more say over the floor plan, materials, and siting, and it means the site conditions of your specific parcel drive both the design and the budget. Building on your own land has been our entire business since 1986, across Volusia, Lake, Marion, and Seminole counties.

Most owners use a construction-to-permanent loan, sometimes called a one-time-close loan. The lender funds the build in draws as work is completed, then the loan converts to a standard mortgage when the home is finished. If you already own your land outright, its value often serves as part or all of the down payment, which is one of the practical advantages of buying a lot first. Your lender will want to see the builder's contract, the plans, and a detailed budget before closing. We're used to supplying exactly what lenders ask for, and we can put you in touch with local lenders who handle construction loans regularly.

It depends on the specific parcel. Orange City, DeBary, DeLand, Deltona, and New Smyrna Beach each run their own municipal building departments, so plans, revisions, and inspections for lots inside those city limits go through the city rather than the county. Parcels in unincorporated Volusia County go through the county's Growth and Resource Management permit and zoning center instead. Florida Statute 553 gives a building department 30 working days to review a completed single-family residential application. Knowing which office governs your lot, and what that office tends to ask for, is part of why local builders can hold a schedule more reliably.

Yes. Rural and acreage parcels across Marion County, west Volusia, and parts of Lake County commonly need a private well and an onsite septic system rather than municipal connections, and we've built on plenty of them. It does need to be planned rather than assumed: septic requires soil evaluation and health department permitting, placement has to respect setbacks from the well, property lines, and any surface water, and both add cost and lead time compared to connecting to utilities already at the road. We'll identify what your lot needs during the site walk so it's in the budget from the beginning rather than appearing as a change order.

More than an ordinary house placed near the water. New Smyrna Beach requires 140 MPH wind design for most residential construction on the beachside and on the mainland between Riverside Drive and the railroad tracks. At that wind speed, wind-borne debris requirements apply, so windows and doors must be tested impact-rated products rather than standard units. Structural connections and roof attachment details follow from the same wind loads. The city also enforces a Coastal Construction Setback Line fifty feet west of the state line, which on oceanfront parcels can determine the buildable footprint before design begins. Salt air additionally argues for corrosion-resistant fasteners, fixtures, and equipment, which costs more up front and much less over the life of the home.

Yes. Thomas J. Mosco Custom Homes holds Florida certified residential contractor license CRC043725. We're a family-owned company that has been building in Central Florida since 1986, with more than 600 custom homes and renovations completed. You're welcome to verify the license through the Florida Department of Business and Professional Regulation, and we're glad to provide current insurance certificates on request before any work begins.

Both. Alongside ground-up custom homes, we take on kitchen and bathroom renovations, room additions, primary suite additions, interior and exterior updates including flooring, trim, windows and siding, and detached garages, workshops, and barns built to match the main residence. The same crews and subcontractors who build our custom homes do the renovation work, which is not true of every builder. If you're weighing whether to renovate what you have or build new, we're happy to look at both honestly rather than steering you toward the bigger job.

We're based in Orange City and build throughout Volusia County, including DeBary, DeLand, Deltona, New Smyrna Beach, Daytona Beach, Port Orange, and Ormond Beach. We also build across Seminole County in Sanford, Lake Mary, Longwood, and Oviedo; in Lake County including Eustis, Mount Dora, Tavares, and Clermont; and in Marion County in and around Ocala. If your lot is somewhere in Central Florida and you're not sure whether it's in range, call and ask. Being genuinely local to a project matters for scheduling and site oversight, so we're honest when something is too far to serve well.
