Detached structures under 144 sq ft exempt. Deck construction generally requires a permit and property survey.
If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
Review the exemption criteria above. If your deck exceeds any threshold, a permit is required.
You'll need a site plan, deck dimensions, framing details, and footing specifications. Check Buffalo's specific documentation requirements.
Apply through Buffalo ePermits . Pay the permit fee at submission.
Once approved, post your permit visibly and schedule required inspections (typically footing, framing, and final).
