Quick answer

Buffalo exempts a single story detached shed, playhouse or similar utility building of 144 square feet or less at a one- or two-family dwelling or townhouse from a building permit and from permit fees. Anything above that area needs a permit, and the residential fee schedule sets a distinct flat fee for sheds and garages over 144 square feet and under 600 square feet. The exemption is conditional even below 144 square feet: the structure still may not alter drainage to a neighbor's detriment, violate the building code or the zoning ordinance, or create a hazard or nuisance.

Typical threshold: gross floor area of a one story detached tool or storage shed, playhouse or similar accessory building at a one- or two-family dwelling or townhouse.

How to apply in Buffalo

A residential shed permit application, once the shed is large enough to require one, is a set of construction documents that show what will be built and prove it meets the adopted residential code. In practice that means a written permit application, a scaled site plan locating the shed and its distances to the property lines, and construction documents covering the shed's foundation or anchoring system and its framing.

What most shed permit applications include:

  • A written permit application identifying the proposed work and describing the property by its address or legal description, filed with the building department before construction begins (IRC R105.3).
  • A scaled site plan showing the shed's size and location and its dimensioned distances to all property lines so required setbacks can be verified before the permit is issued (IRC R106.2).
  • Construction documents showing the shed's foundation: freestanding accessory structures at or under the code's small-structure size and eave-height limits (600 square feet and a 10 foot eave height in the model code) are exempt from continuous footings but must still be shown supported on undisturbed soil or engineered fill and anchored to resist wind-induced uplift and overturning (IRC R403.1).
  • Where the shed does sit on a continuous foundation with a wood sill plate, anchor bolt or approved strap details tying the sill plate to the foundation (IRC R403.1.6).
  • Roof framing details showing the rafter-to-wall or truss-to-wall connections, since even a shed exempt from continuous footings must be anchored to resist wind-induced uplift and overturning (IRC R403.1; R802.11).

Inspections and closing out your permit

A permitted shed is inspected in stages as it goes up: the foundation or the anchors that hold it down before they are covered, the framing before it is enclosed, and a final inspection once the shed is finished. Each stage checks the items that would be hidden or unsafe if skipped.

  1. Foundation or anchor inspection: called after any required footings, piers, or ground anchors are set and any forms or reinforcing steel are in place, but before concrete is placed, so the foundation or anchoring system can be verified before it is covered (IRC R109.1.1).
  2. Frame inspection: after the shed is framed, sheathed, and braced, the inspector checks the framing, bracing, fasteners, and the roof connections that resist wind uplift, before those elements are covered (IRC R109.1.4 frame inspection; R403.1 anchorage).
  3. Final inspection: made after the permitted work is complete and before the shed is used; work may not proceed past any inspection stage without the building official's approval (IRC R109.1.6 final inspection; R109.4 approval required).
  4. For a pre-fabricated or kit shed, the manufacturer's installation instructions must be on site at the time of inspection so the inspector can confirm the anchoring and assembly match the design (IRC R106.1.2).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Buffalo permit portal or by phone at 716-851-4290.

Can a homeowner pull a shed permit themselves in Buffalo?
Under New York law (Inside New York City: NYC Admin. Code 28-104.1, 28-105.1, 28-105.4, 28-105.5.1, 28-401.3 (definition of "general contractor"). Outside New York City: N.Y. Exec. Law 381(2); 19 NYCRR 1203.3(a)(1).): New York State sets no owner-builder rule at all outside New York City. Executive Law 381(2) puts administration and enforcement in the hands of each local government, and 19 NYCRR 1203.3(a)(1) only requires each authority having jurisdiction to make building permits mandatory for work that must conform to the codes, leaving who may apply to local law. The state licenses no general contractors and imposes no owner-builder affidavit, disclosure form or post-permit sale restriction of the kind Florida uses, so whether a homeowner may pull the permit is a question for the specific city, town, village or county. New York City is the genuine outlier. Administrative Code 28-105.1 makes the work itself unlawful without a written permit, and Administrative Code 28-104.1 bars the department from issuing that permit until it approves the required construction documents, which must be prepared by or under the supervision of a registered design professional, meaning a licensed architect or engineer, as required by the code. A homeowner therefore cannot self-prepare and file the plans for permit-requiring work in New York City even though Administrative Code 28-105.5.1 defines the permit applicant as the person who performs the work or retains a subcontractor, and even though the general contractor registration definition in Administrative Code 28-401.3 expressly excludes an individual who constructs a residential structure of no more than three dwelling units for his or her own occupancy. Note that Administrative Code 28-105.4 exempts minor alterations and ordinary repairs from the permit requirement entirely, so the design professional bottleneck applies only to work that needs a permit in the first place. Confirm how Buffalo applies this before you apply.
