Three Common Riverhead Projects Need a Closer Look
Shed
Riverhead allows a limited exception for one shed under 144 square feet on a single-family property when it is in the rear yard and at least 5 feet from property lines.
The exception may not work near wetlands, a bluff or inside the Pine Barrens Overlay District.
Fence
A conforming residential fence generally does not require a Building permit. Front-yard and street-side fencing is generally limited to 4 feet, while side and rear fencing can generally reach 6 feet.
Corner, through, wetland and bluff properties need staff review.
Pool or hot tub
New York requires permits for pools and hot tubs, including many temporary or storable pools.
The Town describes the exception as a pool designed for less than 24 inches of water depth and installed entirely above ground.
Apply for a Riverhead Building Permit in the Correct Order
Identify the property’s zoning and environmental constraints
Check the zoning district, wetlands, coastal zone, floodplain, Pine Barrens, Suffolk County Health jurisdiction, road authority and utility service.
Download the exact Town application
Riverhead publishes separate applications for residential, commercial, pools, demolition, solar, electrical, manufactured homes, signs, bulkheads, use permits and other work.
Complete the application and disclosure forms
The residential package requires a two-page Building Permit Application, Disclosure Affidavit and inspection acknowledgment checklist.
Prepare accurate plans and surveys
Provide the required building plans, plot plans or surveys, energy compliance and design-professional seals. Show existing and proposed construction clearly.
Obtain outside approvals before expecting issuance
Suffolk County Health, CAC, Planning, Fire Marshal, Highway, Water, Sewer, NYSDOT, NYSDEC and other agencies may need to approve or comment.
Submit the forms and pay the nonrefundable fee
Riverhead’s application says processing begins when all applicable forms are received and the required fee is paid.
Deliver the original notarized application
The Building Department expressly states that the original notarized application must be received before permit issuance.
Respond to review comments as one coordinated revision
Answer every Building, zoning, Planning, Fire, Health and environmental comment. Replace all affected sheets and explain each change.
Obtain the permit before beginning work
The Town’s forms state that a permit must be obtained before work begins. Starting without approval can lead to a stop-work order, additional fees and enforcement.
Documents Riverhead Commonly Requires With a Residential Application
Forms and signatures
- Two-page Building application
- Notarized Disclosure Affidavit
- Inspection acknowledgment
- Owner or applicant contacts
- Electrical application
- Project valuation
Plans and property documents

Most Building Plans Need a New York-Licensed Professional’s Seal
Sealed-plan default
Riverhead states that New York education law generally requires a New York-licensed design professional to stamp Building plans.
Plans must remain accurate, complete and drawn to scale even when a seal exception applies.
Limited alteration exception
The Town’s FAQ describes an exception for alterations costing $20,000 or less when they do not affect structural safety or public safety.
A simple basement finish without structural changes is the Town’s example, but the Building Inspector makes the project-specific determination.
Provide the Correct Insurance Certificates
Town-listed residential requirements
- General liability ACORD certificate.
- Town form lists a $2 million / $1 million minimum.
- Workers’ Compensation form C-105.2.
- Disability form DB-120.1.
- Property owner and job location shown.
- Town of Riverhead listed as certificate holder.
Owner-performed work
Use the Town’s Owner Affidavit when applicable and confirm which insurance exemption forms or state documentation the Building Department requires.
Owner-performed work does not authorize unlicensed electrical, plumbing or other regulated professional work.
Check the Zoning District, Permitted Use and Plot-Plan Requirements
Interactive zoning map
Use Riverhead’s current interactive zoning map to identify the likely zoning district.
Town zoning code
Check permitted uses, setbacks, height, lot coverage, parking, signs, accessory structures and special-permit rules.
Plot-plan detail
Riverhead’s zoning rules require plot plans showing lot dimensions, existing and proposed structures, exact locations and information needed to confirm zoning compliance.
Wetlands, Floodplain, Bluffs and Pine Barrens Can Change the Permit Route

|---|---|---|
Within 150 feet of a freshwater wetland |

Commercial Permits Commonly Depend on Several Agencies
Planning Board

Suffolk County Health
Wastewater, septic, food-service and other regulated Health Department approvals.

Riverhead Building Fees Depend on the Town’s Valuation Method
Building permit fee
Fees are calculated under Chapter 217 of the Town Code and are nonrefundable.
The Building Inspector can determine valuation using accepted linear-foot or square-foot methods rather than relying only on the applicant’s contract price.
Large-project planning figure
The Town’s Building FAQ says permit fees for large projects approach approximately 1.2% of estimated construction cost.
This is not a universal quote and does not include all separate approvals or trade permits.
Nonrefundable payment
Riverhead’s Building and CO materials state that permit fees are nonrefundable under Town Code §217-12.
