Find Out What Your NYC Home Addition Actually Costs
The biggest shock about home additions? Contractors who quote $80K and then demand another $60K for 'unexpected' foundation work. Zoning variances that take eight months and cost $15K in fees. Neighbor complaints that shut down your project for months. Permit delays that double your timeline.
