Key Takeaways:
The average cost to build a quality custom home is $350 to $650 per sq. ft. However, there are several moving variables that can shift the cost. Talk to an architect about your budget and goals to explore realistic home construction solutions.
The main factors that drive up costs are square footage, fixtures, and finishes. Don't cut corners on quality building materials and mechanical systems as they impact your home’s longevity and energy efficiency.
A construction feasibility study is critical for accurately estimating home building costs (you don’t want to run out of budget halfway through from unexpected expenses). The study also includes a site analysis, a zoning and regulation review, and scenario planning to guide development.
The Average New Home Construction Cost in Ithaca, NY
The average cost to build a new home in Ithaca, NY, ranges from $350 to $650 per sq. ft. or more, excluding site work or land expenses. It’s important to remember that building expenses can shift due to numerous moving variables. Your level of customization, quality of finishes, labor rates, materials, and local permitting requirements all play a role in shaping the final construction costs.
Consult an experienced architect to get a realistic and accurate custom home cost. Architects will help you explore solutions that fit your goals and budget, including options you might have overlooked. You should also ask for a home feasibility study, which outlines a preliminary construction budget and timeline.
Top Factors That Influence the Cost of Building a Custom Home
While the cost per square foot gives a general estimate, several factors significantly influence your final construction costs, including:
Total Square Footage – In general, the larger the home, the lower the cost per sq. ft. because many expenses, like the land, utility connections, and foundation work, are fixed regardless of the home size. However, a larger footprint means higher upfront costs.
Fixtures and Finishes – High-end finishes like tile, marble, and hardwood flooring can skyrocket construction costs. Couple that with luxury plumbing or lighting fixtures as well as custom cabinetry, and it’s easy to overshoot your budget.
Multiple Stories – Building a multi-story home is more complex than a ranch-style house, from the materials and engineering logistics to the labor, plumbing, and electrical work.
Sustainable Building Materials – While less impactful than square footage and finishes, sourcing quality building materials like sustainable insulation can contribute to higher construction costs. However, the environmental benefits and ease of use often justify the price.
Prefab vs Custom Design – Prefab homes with minimal modifications tend to be less expensive than custom designs because they’re efficient to build and are faster to set up. The materials may also be sourced in bulk, reducing construction costs. Custom design will almost always cost more, but it’s often worth it for the personalization options.
Remember: If you need to cut costs, reduce square footage or scale back aesthetic upgrades—but never skimp on the building envelope (walls, roof, insulation) or mechanical systems (HVAC, plumbing, electrical). These elements impact your home’s long-term comfort, efficiency, and durability.
How to Estimate Construction Costs for Your Home
The most accurate way to estimate construction costs when building a home is to ask a knowledgeable residential architect or construction company to conduct a feasibility study. Companies that provide quick estimates without a proper assessment may underestimate costs down the line, which forces the homeowner to compromise halfway through the project.
Investing in a feasibility study allows you to set a more realistic budget and avoid bait-and-switch estimates that result in unexpected costs. Beware of quotes that seem too good to be true, as they may not consider the whole picture.
What Is a Home Feasibility Study?
A construction feasibility study is a detailed planning process that assesses whether your vision, site, and budget align. The study answers whether it’s possible (and advisable) to build a home. It’s the first step in any construction project—especially for custom homes in Ithaca, NY, where terrain, zoning, and seasonal weather can all affect outcomes.
At Trade Design Build, our architects and builders work collaboratively to give a more accurate assessment of your vision than an architect or construction company alone could. Our feasibility study includes:
A consultation to understand your vision and goals
A site analysis and risk assessment
A space programming outline
A review of zoning and building codes
Preliminary construction budgets & schedule
Development scenarios
Step 1: Understanding Your Vision and Goals
The first step is always an initial conversation to discuss why you want to build a custom home, what the overall look should be, and any additional context (e.g., budget, reference photos, connection to the location, lifestyle preferences).
Aligning with your vision helps us plan ahead and ensure your home meets your needs. Tell us about your must-haves, whether you have any sustainability goals to build a net-zero home, or require accessibility adjustments.
A custom home should feel like an extension of you and your family. Share your insights, and we’ll help you plan a home tailored to you.
Step 2: Conduct a Site Analysis & Risk Assessment
During the site visit, we inspect the land and any existing structures and mechanical systems (if you’re remodeling or expanding). The goal is to understand if the land is suitable for building a structure and account for any risks.
Some of the main things we check for are:
The topography and slope of your land
Soil conditions and drainage
Accessibility for equipment and materials
Utilities (water, sewer, power)
Existing structures or vegetation
Step 3: Outline the Physical Space Programming
Physical space programming helps architects outline what you need in your home and how each room should function. This step considers your current and future space needs, in case you plan on expanding your home or foresee life changes such as starting a family, or elderly parents moving in.
In a nutshell, space programming ensures your space meets your lifestyle and goals. We go over:
Number and type of rooms
Target square footage for each space
Critical adjacencies (e.g., laundry near the mudroom)
Special technical requirements (e.g., ventilation for a workshop)
Step 4: Review Zoning Laws and Building Codes
Architects must ensure that your custom home complies with local zoning laws and building codes. Designing with these regulations from the start helps avoid costly redesigns later on. We evaluate:
Town zoning laws:
Setbacks from property lines
Height restrictions
Maximum building coverage
Local and state building codes:
Energy efficiency standards
Fire safety
Accessibility (for commercial)
Step 5: Determine the Preliminary Budgeting and Scheduling
We determine the preliminary budget and schedule, providing a dollar-per-square-foot estimate based on industry cost data and professional experience. The budget includes hard construction costs, which refer to direct expenses related to the physical construction of the building.
Typically soft costs, or additional expenses for the project, are defined but not estimated unless directed by the client. These soft costs can add up—items such as furniture, appliances, and moving costs need to be considered in an overview of a project.
Trade strives to provide realistic preliminary budgets so owners know what they’re getting into before investing in construction. Budgets may shift as the project progresses, but a good home-building cost estimate should not be lower just to mask hidden expenses.
A realistic budget also allows us to work with homeowners early on to identify solutions to meet their budgeting goals, and if lending is needed, it will help secure a loan from a banking institution.
Homeowners will also receive a timeline outlining the key project phases (design, permitting, construction) to manage expectations.
Step 6: Provide Development Scenarios
In construction, scenario planning helps homeowners predict and prepare for different outcomes based on uncertainties and risks. Think of it as a “best-case vs worst-case” outline. Development scenarios show how construction can adapt if something doesn’t go according to plan.
Risks might include:
Fluctuating material costs
Regulatory changes
Finishes & fixing availability
To reduce choice fatigue, Trade recommends the best path forward and works with you to pivot seamlessly.
Do I Need a Feasibility Study for My Custom Home?
Yes, we recommend feasibility studies for all large design and construction projects, such as a custom home or a renovation. Feasibility studies are a key part of the preconstruction phase and help homeowners accurately understand potential costs and how they align with their budgets.
Construction feasibility studies are especially important if:
You’re building on a waterfront or sloped property
The site has complex features (like poor soil or protected wetlands) that require advanced analysis
Your custom home has unique features (roofing, balconies, layout, etc.)
You’re planning an addition to an existing structure
You want to avoid costly surprises or delays
Some projects may require a GIS (Geographic Information System) report for advanced site analysis or follow different zoning laws than suburban or city homes. That’s why many local architects in Ithaca recommend feasibility studies as a best practice.
