- Soft costs often add roughly 15 to 25 percent to construction in 2026 planning terms, depending on scope and building.
- Most alterations are filed in DOB NOW: Build by a New York State registered architect or licensed professional engineer.
- Expediters manage paperwork and agency follow-up; they do not replace the design professional of record.
- Co-op and condo reviews, insurance certificates and landmark approvals add time and sometimes fees.
- Ask every bidder whether design, filing, expediting and board paperwork are included, excluded or allowances.
Ask five New Yorkers what their renovation cost and you will get five numbers. Ask them what portion went to architects, engineers, expediters and permits and most will pause. Those costs are real, they are often large, and they are easy to leave out of a first budget.
This guide explains what those soft costs are, who charges them, how they are structured and where they stretch in New York City, Long Island and nearby New Jersey. Figures are 2026 planning ranges as of October 2026, not quotes. When you want a bid that shows soft costs and construction in one place, you can request a free estimate.
1. What "Soft Costs" Means
Construction people split a budget into hard costs and soft costs. Hard costs are what you can touch: demolition, framing, tile, cabinets, paint. Soft costs are the professional services and approvals that make the hard costs legal and buildable.
A typical soft-cost list for a New York apartment or house renovation includes:
- Architect or engineer design fees, including drawings and specifications.
- Filing and permit fees with the Department of Buildings.
- Expediter fees for paperwork and agency follow-up.
- Co-op or condo review fees, including the building's architect or engineer.
- Insurance certificates and building deposits.
- Special inspections and testing, where required.
- Hazardous materials surveys for older buildings.
- Landmarks review costs, where the property is designated.
As a planning figure, these items together often add roughly 15 to 25 percent on top of construction. On a $200,000 construction budget, that would suggest roughly $30,000 to $50,000 in soft costs. A cosmetic refresh may need almost none. A full gut renovation with moved plumbing and a new layout may need all of them. Your own number depends on your scope, so use these ranges only to start the conversation.
2. When You Need a Design Professional
Not every project needs an architect or engineer. The question is whether the work requires a DOB filing.
In New York City, most construction work needs a Department of Buildings permit. Alterations are filed through DOB NOW: Build by a New York State registered Design Professional, meaning a licensed Professional Engineer or Registered Architect, who serves as the Applicant of Record. The DOB groups applications into types: New Building, Alteration-CO for changes to use, egress or occupancy, and plain Alteration. Some renewals and filings remain in the legacy systems.
Cosmetic work such as painting generally does not need a DOB permit. But "no city permit" does not mean "no rules." Co-ops, condos and landlords have their own requirements, and some work that looks cosmetic, like removing a wall or touching plumbing, crosses the line. The DOB's guide to obtaining a permit is the authoritative starting point, and our walkthrough of how to get a building permit for your NYC renovation covers the steps. If you are unsure, try the Do I Need a Permit tool or read the step-by-step guide on whether you need an NYC renovation permit.
Projects that usually need a filing
- Moving or adding plumbing fixtures, risers or gas lines.
- Removing, adding or relocating walls.
- Changing electrical service or adding significant circuits (see the NYC electrical permit guide).
- Structural changes, new openings and additions.
- Changes to egress, use or occupancy.
Projects that often do not
- Painting, wallpaper and minor repairs.
- Like-for-like replacement of finishes.
- Many flooring and tile changes that do not alter structure, waterproofing assemblies or systems, subject to your building's rules.
When in doubt, ask the DOB or a design professional rather than guess.
3. How Architects and Engineers Charge
Fee structures vary, and no single method is best. Knowing the options helps you compare proposals.
| Fee structure | How it works | Best for | Watch for |
|---|---|---|---|
| Flat fee | One price for a defined scope | Clear, contained projects | What counts as a revision, and what is extra |
| Percentage of construction | A percentage of the construction cost | Larger design-led projects | Fee rising as scope or finishes rise |
| Hourly | Time billed as spent | Small or uncertain tasks | No cap on total |
| Phased | Separate fees for concept, filing and construction support | Complex projects | Gaps between phases |
Whatever structure you choose, ask what is included. Typical deliverables are a field survey, existing-conditions drawings, proposed plans, filing documents, responses to DOB objections, and some construction-phase support. Site visits, shop drawing review and sign-offs may or may not be included. The difference between a low proposal and a high one is often a few paragraphs of scope.
Engineers
Some projects, especially those involving structure, mechanical systems or expansive electrical work, call for an engineer in addition to or instead of an architect. Co-ops and condos may also require review by the building's own engineer, whose fees can be passed to you.
4. What an Expediter Does, and What They Do Not
An expediter is a specialist who knows how the city's filing systems and agency procedures work. They prepare and submit paperwork, track applications, respond to objections, schedule inspections and keep the process moving.
What an expediter does not do is replace the design professional. The architect or engineer signs and seals the filing and is responsible for its content. An expediter handles the logistics around it. Some firms combine both roles, and some contractors offer both in-house.
That is how we work. We design and build in-house, and we prepare and coordinate DOB filings and co-op or condo board paperwork for clients, so you are not juggling an architect, an expediter, a contractor and a managing agent who never speak to one another. When a plan examiner raises an objection, the same team that drew the plan responds, and the same team that builds it hears the answer.
Here is what that looks like for you in practice:
- We visit and measure, and talk through your goals and your building's rules.
- We prepare drawings and, where needed, work with the registered design professional of record.
- We assemble the board package: alteration agreement, drawings, insurance certificates and schedule.
- We handle the DOB NOW filing and follow-up.
- We start work only when the approvals your project requires are in place.
Your estimate shows each of these as a line, so you can see what you pay for design and approvals separately from construction. Pricing is transparent with detailed contracts and no hidden fees.
5. Permit and Filing Costs
DOB fees depend on the type and size of the filing, and they change over time, so we do not quote a number here. Check the DOB for current fee schedules and service updates, and review the agency's service updates page for changes that may affect timing.
Beyond DOB fees, ask about:
- Costs for required inspections and sign-offs.
- Special inspections for structural or fireproofing work.
- Sidewalk shed or protection costs for exterior work. New sidewalk shed rules took effect August 13, 2026.
- Fees for Landmarks Preservation Commission applications, where applicable.
- Fees for plan revisions after an objection.
It is common for permit and filing costs to appear in a contract as a pass-through or an allowance. Make sure you know which, and who owns any refund or overage.
Rules coming down the road
As of October 2026, current rules still apply to alteration applications. Local Law 33 of 2026 enacts a new NYC Existing Building Code that replaces the 1968 code for alterations, and the DOB says it takes effect July 17, 2027. Projects filed after that date will be governed by the new code, which may change some details of design and filings. If your project straddles that date, ask your design team how it affects you. The city's construction codes page is the place to follow the details.
6. Co-op, Condo and Landlord Review Costs
If you own in a co-op or condo, the building's process is often the longest and most expensive part of soft costs.
The alteration agreement
Boards typically require a signed alteration agreement, drawings, a contractor's license and insurance, a schedule and proof of coverage. Many require approval of the contractor before the agreement is signed. Some boards charge review fees or require you to reimburse the building's architect or engineer. Industry reports say that DOB reinstated, effective January 26, 2026, a board attestation inside DOB NOW: Build confirming that alterations are board-approved. Confirm the current requirement with DOB and your managing agent.
Insurance
Buildings usually require a certificate of insurance naming the building and its managing agent. See our guide to the certificate of insurance for NYC renovations for what to ask your contractor for and how long it takes.
Time and money
Board review can add weeks, and sometimes months, between your first submission and a signed agreement. That time has a cost: carrying costs, delayed start, longer temporary housing. Build it into your plan, and ask your managing agent for the board's meeting calendar before you set a start date.
7. Landmarks and Historic Districts
Landmarked buildings and historic districts add a separate approval layer. The Landmarks Preservation Commission issues three main permit types: Certificate of No Effect, Permit for Minor Work and Certificate of Appropriateness. LPC review is required before exterior changes, and sometimes certain interior work, on landmarked properties. The LPC explains the process on its permit applications page.
Landmark work often adds roughly 15 to 20 percent to time and budget, in part because of design documentation and material requirements. If your property is in a historic district, add landmarks review to your soft-cost list and ask your design team how much of the work is exterior.
8. A Worked Example
Here is an illustrative, round-number example. It is not a quote, and it is not based on any specific project.
Imagine a two-bedroom pre-war apartment gut renovation with a new kitchen and bathroom layout. Construction is budgeted at $300,000. Using the planning range of roughly 15 to 25 percent for soft costs, the owner should expect something like $45,000 to $75,000 in design, engineering, filings, expediting, board review and testing, on top of the construction price.
| Budget line | Illustrative amount |
|---|---|
| Construction | $300,000 |
| Soft costs at 15% | $45,000 |
| Soft costs at 25% | $75,000 |
| Total at low end | $345,000 |
| Total at high end | $375,000 |
| Contingency at 10 to 20% of construction | $30,000 to $60,000 |
The point of the exercise is not the arithmetic, it is the shape. Soft costs are not rounding errors. And contingency is a separate reserve, not part of soft costs. Our guide to hidden costs in NYC renovations lists the other items worth reserving for, and the renovation cost guide gives full planning ranges for construction.
9. Why a Licensed Pro Saves Money on Soft Costs
It sounds odd that hiring a contractor who handles approvals can lower your total, but it often does, for three reasons.
Fewer handoffs. Every time a drawing, a filing or a question passes between separate firms, hours are billed and details are lost. A team that designs and builds in-house reduces that friction.
Drawings that can be built. An architect who does not build may draw something that costs more than expected or conflicts with the building's rules. A design-build team prices as it draws.
Fewer rejections and stoppages. Filings that match what is built avoid inspector objections and stop-work orders. Unpermitted work can complicate a sale, an insurance claim or a board approval, and fixing it later costs more than doing it right.
New York City requires a Home Improvement Contractor license for residential remodeling work, and the DOB requires permits for most construction. Using an unlicensed handyman for a bathroom or kitchen can leave you with work that has no permit, no insurance and no paper trail. If something leaks, the board does not care who you paid. We are licensed and insured, we prepare permits and board paperwork, and we give you one itemized estimate for the entire package. You can start with a free estimate and see the numbers.
10. Neighborhoods and ZIP Codes We Serve
Soft costs vary by building type and by who regulates it. Here is how local conditions shape them in the areas we serve.
- Tribeca (Manhattan): 10013, 10007. Cast-iron lofts, condo conversions and an LPC historic district. Strict co-op and condo alteration agreements and freight-elevator scheduling add review time. Read our page on luxury apartment renovations in Tribeca.
- Greenpoint (Brooklyn): 11222. Wood-frame row houses and new waterfront condos. Row house work often needs a DOB filing for structural or plumbing changes, while newer condos bring board rules. See luxury apartment renovations in Greenpoint.
- Ridgewood (Queens): 11385. Ridgewood Historic District brick row houses and multifamily buildings. Landmark review applies to exterior changes, and multifamily buildings may need coordination with other units.
- Annadale (Staten Island): 10312. Detached homes and townhouse complexes. Townhouse associations may have their own exterior rules on top of DOB requirements.
- Baldwin (Nassau County, Long Island): 11510. Capes, ranches and flood-prone pockets. Permits come from the responsible town or village building department, and flood-zone rules may affect design.
- Short Hills (Essex County, NJ): 07078. Large colonials and estates in Millburn. Permits come from the local construction office under the NJ Uniform Construction Code, and larger homes often involve more design work.
We serve all five boroughs, Nassau County and western Suffolk, and northern and central New Jersey within about a 50-minute drive of NYC.
11. Ways to Control Soft Costs
You cannot skip soft costs, but you can manage them.
- Define scope before you hire. A clear list of rooms and goals gets better proposals and fewer revisions.
- Ask for itemized proposals. Know what the architect, expediter and contractor each include.
- Decide on finishes early. Late changes can mean revised drawings and refiling.
- Check building rules first. Surprises from the board cost the most time.
- Avoid moving plumbing when you do not need to. Relocating fixtures often triggers filings and structural work.
- Submit complete packages. Missing documents delay board and DOB review.
- Bundle services when it makes sense. A single design-build contract can reduce handoffs.
- Plan for time. Delays cost more than fees.
Design also matters beyond cost. Thoughtful layouts, ventilation and lighting affect how a home feels and functions, which is covered in our article on home design and health. Check how upgrades affect value with the renovation ROI calculator.
