If you’re buying a home on Long Island and wondering what a home inspection will run you — you’re not alone. It’s one of the first questions buyers ask, and the answer depends on a handful of factors that are worth understanding before you book.
Typical Home Inspection Costs in Nassau and Suffolk County
For a standard single-family home inspection in Nassau County or Suffolk County, expect to pay between $400 and $650. The range comes down to the size of the home, its age, and any add-on services you request.
- Small homes (under 1,500 sq ft): $375–$450
- Mid-size homes (1,500–2,500 sq ft): $450–$575
- Larger homes (2,500+ sq ft): $575–$700+
- Multi-family homes: Add $75–$150 per additional unit
What Add-Ons Affect the Price?
A basic inspection covers the structure, systems, and major components of the home. But Long Island homes — especially older ones in communities like Levittown, Mineola, or Bay Shore — often have additional concerns worth testing for.
- Radon testing: $100–$150. Long Island has documented radon risk, especially in basements.
- Mold inspection: $150–$300 depending on scope. Common in older homes and post-storm properties.
- Oil tank sweep: $100–$200. Many older Long Island homes had underground oil tanks. Finding one late is expensive.
- Sewer scope: $150–$250. Older clay pipes are common in Nassau County neighborhoods.
- Pool inspection: $75–$125 as an add-on. Essential if the home has an in-ground pool.
Is It Worth Paying More for Experience?
Short answer: yes. A home inspection is not the place to find the cheapest option. A thorough inspector who knows Long Island construction — the common issues in Cape Cods in Nassau, the basement drainage problems in Suffolk, the flat-roof parapet issues in Brooklyn-adjacent neighborhoods — will find things a less experienced inspector misses.
