Sample insight
Mid-range full-gut bathroom remodels in downstate New York typically run $28,000–$55,000 per bathroom in 2026, with NYC co-op renovations commonly 25–45% above that range once alteration agreement, insurance, and after-hours work rules are accounted for. Pre-war homes routinely absorb $4,000–$10,000 in unplanned cast-iron drain or galvanized supply remediation discovered after demo. (Estimate based on 2024–2025 New York permit and bid data.)

Frequently asked
What homeowners ask before downloading.
Does the report cover co-op and condo alteration agreements?
Yes. We separate building-code scope (DOB filings, plumbing rough, electrical) from alteration-agreement scope (managing-agent fees, insurance riders, after-hours premiums, escrow) and show how the latter commonly adds 15–30% to a downstate renovation.
How are allowances for tile, vanity, and plumbing handled?
We publish realistic 2026 allowance ranges for each finish category and call out the specific places contractors under-allowance to win bids.
Will I get added to a contractor lead list?
