Small additions (200–400 sq ft) typically take 3–6 months from permit approval to completion. Permitting alone can take 1–3 months depending on jurisdiction.
For anything structural or over $10,000, a licensed general contractor is strongly recommended. They coordinate permits, subcontractors, and inspections — and carry liability coverage you'd otherwise lack.
