What Northern Westchester Architects Actually Charge in 2026

WestchesterCost & BudgetWorking With Pros

Feb 6

"How much does an architect cost?" is a question with a wider answer in northern Westchester than almost anywhere else in the country. The same scope of work — say, a $600,000 addition with kitchen remodel — might come back at $42,000 from a solo practitioner working out of their home in Bedford Hills, $68,000 from a four-person boutique studio in Chappaqua, and $108,000 from a full-service residential firm in Armonk that includes interior design and construction administration. All three numbers are reasonable. They buy genuinely different services.

This is a no-spin 2026 walkthrough of what northern Westchester architects actually charge, the three main fee structures, what is and isn't included in "basic services," the phase-by-phase breakdown of where the fee gets spent, and the reimbursable categories that quietly add 3 to 8 percent on top of the headline number.

The three fee structures and when each one is used

Hourly billing — $175 to $325 per hour for a principal

Hourly billing dominates the early stages of a project and the smallest scopes. A two-hour consultation about whether to add or move, a feasibility study on a tight Pleasantville lot, or schematic ideas for a master suite addition are typically billed hourly. Principal-level architects in northern Westchester land in the $175 to $325 per hour range in 2026, with senior associates at $135 to $200 and drafters or junior staff at $90 to $150.

Hourly is the right structure when scope isn't yet defined and the homeowner is paying for thinking time, not deliverables. It becomes less useful — and less popular with both sides — once the project is committed and the scope is large enough to estimate.

Percentage of construction cost — 8 to 18 percent

For full-service residential work, percentage-of-construction-cost is the long-standing default. The architect's fee is calculated as a percentage of the actual built construction cost, typically:

8–10 percent for a basic addition or kitchen remodel where the architect produces drawings and the GC handles most of the rest.
10–14 percent for a substantial addition, gut renovation, or whole-house remodel including drawings and construction administration.
14–18 percent for high-end residential work with custom millwork, interior design integration, and detailed construction administration through closeout.

The percentage typically ticks up for smaller jobs (where fixed costs eat a bigger share) and down for larger ones. It's also higher for renovations than for new construction, because more time is spent on field measurement, existing-condition documentation, and unexpected discoveries.

Fixed fee — $25,000 to $120,000+ per project

Fixed-fee structures have become more common as homeowners ask for budget certainty. Once scope is defined, the architect proposes a lump sum tied to specific deliverables (concept, design development, permit set, construction documents, and a stated number of construction-administration site visits). Typical 2026 numbers in northern Westchester:

Smaller addition or kitchen/bath remodel: $25,000 to $45,000 fixed fee.
Major addition or substantial remodel: $45,000 to $85,000.
Whole-house gut renovation or new build: $85,000 to $120,000+, scaling with square footage and finish level.

Fixed fees come with stated assumptions and a clear change-order mechanism if scope grows. The trap is signing a fixed fee against a scope that isn't actually pinned down — both sides end up unhappy.

What "basic services" actually includes

The architect's standard scope, regardless of fee structure, is typically organized into five phases:

Schematic design (SD), ~15% of fee: programming, site assessment, two to three concept options, preliminary floor plans and massing.
Design development (DD), ~25% of fee: dimensioned plans, elevations, sections, key details, preliminary structural and MEP coordination.
Construction documents (CDs), ~35% of fee: permit-ready drawings with full notes, schedules, and details. This is where the architect produces the document set the contractor builds from.
Bidding/negotiation, ~5% of fee: assistance qualifying contractors, reviewing bids, and negotiating contract terms.
Construction administration (CA), ~20% of fee: site visits, RFI responses, submittal review, change order coordination, and punch-list at closeout.

The last phase — CA — is where homeowners often try to save fee by self-managing, and it is also where the architect's value is most concentrated. Cutting CA on a $1.2M whole-house renovation is the single most common false economy in this market.

What is NOT included in basic services

The phrase "additional services" appears in every architect's contract and it covers a meaningful list of items homeowners often assume are baked in:

Site survey: a topographic and boundary survey from a licensed land surveyor — typically $1,800 to $4,500 in this part of the county.
Structural engineering: a stamped structural design from a licensed PE — typically 15 to 25 percent of the architect's fee for the relevant scope.
MEP engineering: mechanical, electrical, plumbing engineering for projects beyond standard residential code work.
Geotechnical investigation: soil borings or test pits if foundation conditions warrant.
Landscape architecture: separate from architectural site planning; covers planting, hardscape, and outdoor living.
Interior design: millwork detailing, furniture selection, finish curation. Some firms include this; many bill it separately.
Permit expediting and zoning analysis beyond the basic level: ZBA variance pursuit, site plan defense at Planning Board, Conservation Board appearances. These often run on hourly billing in addition to basic services.
3D renderings, animations, virtual reality walkthroughs: typically additional services unless explicitly included in scope.

Reimbursable expenses — the line item homeowners forget

"Reimbursables" are the architect's pass-through costs paid by the owner separately from the fee. Typical reimbursable categories include printing and plotting (less than it used to be, but still meaningful for permit submissions), travel beyond a reasonable radius, courier and overnight delivery, application fees paid on the owner's behalf, and consultant subcontracts the architect coordinates. On a typical residential project, reimbursables run 3 to 8 percent of the architect's fee. Always ask whether reimbursables are billed at cost or with a markup (10 to 15 percent is standard for the markup case).

How firm type affects what you pay and what you get

Solo practitioner ($175–$225/hr; 8–12% of construction)

A licensed architect working alone or with one drafter — often based out of a home office in Bedford Hills, Mount Kisco, or Pleasantville. Strengths: principal involvement throughout, lower overhead, deep local relationships. Limitations: capacity to handle multiple complex projects simultaneously, occasional speed bottlenecks during high-demand seasons.

Boutique studio of 3–6 ($225–$275/hr principal; 10–14% of construction)

A small partnership or principal-led studio with one or two associates and project staff. Strengths: enough capacity to handle a substantial project's full lifecycle, design depth across rooms and details, integration with structural and MEP consultants. The most common fit for a high-quality $1M to $4M residential renovation.

Full-service firm of 8+ ($275–$325/hr principal; 12–18% of construction)

A residential firm with in-house interior design, construction administration specialists, sometimes landscape architecture. Strengths: integrated delivery across architecture and interiors, deep CA capacity, full-service white-glove project management. Higher fee reflects broader scope and deeper bench.

When the fee feels high — and when it actually is

The honest framing for homeowners: the architect's fee is one of the smallest line items in a renovation budget, and one of the highest-leverage. On a $1.2M gut renovation, the architect's basic-services fee at 12 percent is roughly $144,000. A poorly designed addition, an oversized HVAC system, an inefficient circulation pattern, or a contractor selection without proper bid review can each cost the owner the full architect fee and more. The right architect saves money in three or four places that aren't visible on the fee proposal.

The fee is too high if the firm doesn't have the right experience for the project type, doesn't return calls, hands off to junior staff after sale, or won't commit to a clear scope. The fee is fair if the principal walks the site, asks hard questions before drawing, and produces a document set the contractor can build from without repeated RFIs.

Questions to ask before signing the contract

Is this fee fixed, hourly, or percentage-based — and what triggers a change order?
Which phases are included? What does "construction administration" specifically cover, by site visit count?
Are structural, MEP, civil, and survey consultants subcontracted to you or contracted separately by me?
How are reimbursables billed — at cost, or with a markup?
Who is the day-to-day contact, and how often do I see the principal?
How many projects of similar scope are in your studio simultaneously right now?
What does your typical timeline look like from contract signing to permit submission?
Will you provide three references with similar projects in northern Westchester?

Frequently asked questions

Can I just get drawings and skip construction administration?

Yes, but understand what you're trading. CA is where the architect catches contractor errors, coordinates submittals, and resolves field conditions that almost always vary from the drawing set. Owners who skip CA on substantial projects are signing up to do that work themselves, often without the experience to do it well.

Why is renovation more expensive per square foot than new construction?

Existing-condition documentation, field verification, structural unknowns, working around what's already there, and far more decisions per drawing. The percentage-fee differential between a new build and a comparable renovation is often two to four percentage points, and it's earned.

Do I need a licensed architect, or can a designer or drafter do my project?

For projects requiring a building permit in New York State, drawings must generally be prepared and stamped by a licensed architect or licensed professional engineer. Exceptions exist for very small projects but most renovations of meaningful size need a licensed signature on the drawings.

Should I get three quotes before deciding?

Two to three is the sweet spot. More than that and the design conversation becomes shallow because the architect knows they're competing on price; fewer than two and you don't have a benchmark. Treat the proposals as buyable services, not as identical commodities — they aren't.

What is a typical retainer at contract signing?

10 to 25 percent of the basic services fee, applied as a credit against the final invoice. Some firms structure it as a non-refundable mobilization fee for early concept work.

Use a planning tool to scope architect fees against your project

The cleanest way to size an architect fee is to compare it against the realistic construction cost and the permit complexity of your project. CostWut generates 2026 construction cost estimates by project type and town, which lets you back into a realistic architect fee in dollar terms. PermitWut identifies whether your project will require Planning Board, Conservation Board, or ZBA appearances — which materially changes how much CA and additional services time the architect needs to budget for.
