7 mistakes that blow addition budgets
- 1Skipping zoning & setback checks — 'we'll figure out setbacks later' is how an addition gets stopped mid-build.
- 2Ignoring what's underground — soil, rock, water table, and existing footings decide your foundation cost.
- 3Under-budgeting the structural — engineering stamps, beams, and the load path from new to existing.
- 4Forgetting the systems tie-in — extending HVAC, electrical, and plumbing is a whole second budget.
- 5Choosing a contractor on price alone — the low bid almost always costs more, especially on an addition.
- 6No clear contract or payment schedule — scope creep and disputes start here, and additions grow fast.
- 7Designing too big before pricing the square foot — every extra foot multiplies foundation, framing, systems, and finishes.
Your 5-step plan
- 1Define the addition you actually need — separate must-have square footage from nice-to-have.
- 2Set a realistic budget per square foot, including a 15–20% contingency.
- 3Check zoning, setbacks, lot coverage, and HOA / town rules up front.
- 4Choose a licensed, insured contractor with real local addition experience.
- 5Lock the scope, drawings, schedule, and payment plan in writing.
What to gather before you talk to a contractor
- A few photos of your home and lot as they are today
- A rough site plan and lot size (setbacks matter)
- Your realistic budget range
- Your must-have rooms and your 'would be nice' list
- Your target timeline — additions run weeks to months
