Why Hiring a Design Professional is important
In New York City, you often need a licensed architect or engineer to renovate legally. These professionals—called Registered Design Professionals or RDPs—are the only ones allowed to submit plans to the Department of Buildings (DOB). If your job needs a permit, it likely needs an RDP.
Understanding Design Professionals in NYC
In New York State, only licensed architects and engineers qualify. They can submit drawings, plans, and technical specs to the DOB. If they’re not on board, your plans won’t get approved.
-
A "Registered Design Professional" is an architect or engineer licensed and registered to practice in New York State.
These professionals are authorized to submit plans, drawings, and specifications to the DOB for approval.
For most construction projects in NYC, plans must be submitted to the DOB by a registered architect or professional engineer.*
This requirement ensures that designs meet safety standards and comply with all applicable codes.
When is Hiring a Design Professional Mandatory?
-
If your renovation touches structure, egress, or major systems, the city likely requires stamped plans from an RDP.
-
Many boards demand plans from licensed professionals—even when DOB doesn’t.
-
The more moving parts, the more likely you’ll need expert design and documentation.
Ask yourself these questions
What type of building do you live in?
Single-family? Townhouse? Co-op? Condo? Each has different rules. Architects know how to navigate them.
Where’s your property?
NYC? The Hamptons? A landmarked district? Local codes change by borough and town. An architect stays current so you don’t have to.
What kind of work are you doing?
Painting is one thing. Moving walls or reworking plumbing is another. Architects understand what triggers code reviews and permits.
Will you need DOB filings or board approvals?
Most projects in NYC need both. Architects handle the technical drawings and submissions that get approvals.
Are you changing fire safety, exits, or exterior walls?
If so, you’re in legal territory. Architects are trained to design safe, compliant plans that pass review.
Is your budget over $50,000?
If you’re investing this much, you can’t afford design mistakes. An architect helps you spend wisely and avoid costly rework.
“Generally speaking, architects aren’t just drawing plans—-that’s a draftsperson.) Architects are interpreting laws, solving spatial problems, and protecting your investment from day one.”
Navigating the Complex Building Code Landscape
New York has overlapping codes—state, city, and local. It’s easy to miss something unless you work in this every day. Architects and engineers understand:
NYC Building Code
Local zoning
Historic district rules
Accessibility laws (ADA, FHA)
Energy codes (NYCECC, ECCNYS)
They make sure your design meets the letter of the law—and catches issues before they cost you.
Outside of New York City
Even outside the city, local rules vary. Hamptons villages, upstate towns, and other jurisdictions may restrict:
Height
Setbacks
Lot coverage
Style
A local professional knows what’s allowed—and how to make your plans fit.

accessibility laws
Multi-family buildings with four or more units must meet federal access rules. In NYC, that applies to all of them. Elsewhere, it depends on whether there’s an elevator. A good design team handles this without drama.
Making Every Square Foot Count
New York defines what counts as a legal room:
At least 80 square feet for any room
At least one 150-square-foot room per unit
Bedrooms at least 8 feet wide (with exceptions)
You won’t pass DOB review if you miss these. A professional keeps you on track..
Energy Efficiency Isn’t Optional
New builds and many renovations must meet energy codes. You’ll need to show compliance. Your designer helps with:
Envelope insulation
Mechanical system sizing
Window specs
Lighting and appliance efficiency
Skip this, and your permit stalls—or your bills go up.
Design Is Full of Small Decisions
Good design isn’t just code compliance. It’s thousands of decisions: how walls meet floors, how light moves through a space, how you access storage. An architect or interior designer helps make these calls before mistakes get built.
we Also manage the Process
Hiring a professional helps with:
Code-compliant drawings
Permit applications
Contractor coordination
Site issues
Quality control
They reduce risk, catch problems early, and save time.
Boards Require It for a Reason
If you live in a co-op or condo, your board likely mandates licensed professionals. This protects:
Building structure
Shared systems
Neighboring units
Property value
Skipping this puts you—and others—at risk
Final Thought
Even if you're tempted to go it alone, most NYC projects require a professional. And even when not legally required, hiring one often saves money, time, and headaches.
If you’re unsure, ask early or check your building rules. You’ll get clarity—and avoid costly surprises later.
