Katonah Real Estate Market Shock? What Happened in June 2026

Katonah-Lewisboro Real Estate Market Update: June 2026

Navigating today’s suburban real estate market requires good timing, hyperlocal data, and a clear understanding of how each community is changing. As an active real estate professional in Westchester County, I review these numbers to help buyers and homeowners better understand current conditions.

If you are looking for real estate information about Katonah, Lewisboro, and the surrounding school district, here is how the market performed through June 2026.

Living in and Around Katonah

When I am not analyzing market numbers or showing homes, you can often find me enjoying the communities of northern Westchester. On a typical Sunday morning, I enjoy walking my dog, Milo, into Katonah.

I usually park on Bedford Road, walk along Allen Place, stop for coffee at Tazza, and stroll past the local shops before turning onto the parkway. That familiarity with the streets, businesses, and character of the area is one of the reasons I enjoy working with people interested in the Katonah-Lewisboro community.

🏡 Single-Family Homes

The single-family sector continued to demonstrate substantial price appreciation, even as overall transaction volume slowed because of limited inventory.

• Median sale price: $1,430,000, up 36.8% compared with June 2025
• Unit sales: 24 homes, down 17.2% year over year
• Days on market: 28 days, down 39.1%
• Median sale price per square foot: $433, up 2.5%
• Inventory: 46 active listings, down 29.2%
• Months of supply: 3.08 months, down 31.6%
• Market activity: 92% of homes sold within 90 days, while 88% sold for more than 95% of their original asking price

These figures point to a competitive environment for buyers. I recently showed several single-family homes in the area and watched my clients face intense highest-and-best situations—even with a planned 50% down payment.

For homeowners considering a move, limited competing inventory may create a favorable selling opportunity. However, every property and personal situation is different, so pricing and timing should be evaluated individually.

🏢 Condominiums

The condominium segment experienced a substantial increase in median pricing, along with a notable reduction in the number of available choices for buyers.

• Median sale price: $551,250, up 25.3% compared with June 2025
• Unit sales: 2 condominiums, down 60% year over year
• Days on market: 11 days, down 80.4%
• Median sale price per square foot: $380, up 11.8%
• Inventory: 6 active listings, down 33.3%
• Months of supply: 4 months, down 3.7%
• Market activity: 100% of the condominiums sold within 90 days and for more than 95% of their original asking prices

Important context: Only two condominium sales were included in this period. With such a small sample, percentage changes can appear unusually large and should be interpreted cautiously.

🏘️ Multifamily Properties

There were no multifamily sales recorded in the reported area during June 2026. This type of property remains scarce in the immediate market, meaning that a new multifamily listing may attract significant attention.

The absence of sales does not establish a reliable market price or trend for multifamily properties. A longer reporting period and property-specific analysis would be needed.

🏙️ Co-ops and the Combined Market

Standalone co-op data was limited in the aggregate district report. However, the combined figures across the reported housing categories continued to show limited inventory and strong pricing:

• Combined median sale price: $1,325,000, up 38.7% compared with June 2025
• Combined unit sales: 26 properties, down 23.5%
• Combined days on market: 27 days, down 42.6%
• Combined inventory: 53 available properties, down 28.4%
• Combined months of supply: 3.2 months, down 28%

📌 What This Could Mean for Buyers and Homeowners

The June 2026 figures show a market characterized by limited inventory, rising median prices, and relatively fast sales. Buyers should be prepared before visiting properties, understand their financing, and carefully evaluate comparable sales before making an offer.

Homeowners should avoid assuming that every property increased by the same percentages shown in the broader report. Location, condition, renovations, property type, lot size, school-district boundaries, and recent comparable sales can all influence an individual home’s market value.

New York's New Lead Paint Testing Law: What Home Sellers Need to Know Before August 1, 2026

Proposed New York Lead Paint Testing Requirements: What Westchester County Home Sellers Should Know

Important Disclaimer: As of the date this article is published, the proposed lead paint testing requirements discussed below have not been passed by the New York State Legislature. Any proposed legislation, regulations, implementation dates, or compliance requirements may change before becoming law.

This article is provided solely for informational and educational purposes and is not intended to provide legal advice, environmental advice, tax advice, or real estate advice. Homeowners, buyers, sellers, landlords, and real estate professionals should consult with a qualified New York attorney before making decisions regarding lead paint testing, compliance requirements, or real estate transactions.

New York lawmakers and housing advocates have discussed new lead paint testing requirements that could potentially impact residential real estate transactions in the future. While these requirements have not been enacted as law at the time of writing, homeowners throughout Westchester County should stay informed about potential changes that may affect the sale of older homes.

Thousands of homes in New Rochelle, White Plains, Mamaroneck, Rye, Larchmont, Katonah, Bedford, Lewisboro, and surrounding communities were built before 1978 and could potentially be affected if similar legislation is adopted in the future.

What Are the Proposed Lead Paint Testing Requirements?

Proposed Effective Date

Some discussions surrounding the proposal have referenced an implementation date of August 1, 2026. However, no final legislation has been adopted as of this writing.

Properties Potentially Affected

If enacted, the proposal could apply to:

• Single-family homes built before 1978
• Two-family homes built before 1978
• Condominiums built before 1978
• Cooperative apartments built before 1978

The year 1978 is significant because lead-based paint was banned for residential use in the United States that year.

Potential Requirements for Sellers

Under various discussions surrounding the proposal, sellers could potentially be required to complete certain actions before entering into a binding contract.

These requirements could include:

• Hiring a certified lead paint inspector
• Obtaining a lead-based paint inspection report
• Providing the report to prospective buyers
• Filing documentation with state agencies
• Providing compliance records during the transaction process

Because legislation has not been finalized, homeowners should not rely on these potential requirements without consulting qualified legal counsel.

Why This Matters in Westchester County

Westchester County contains a substantial number of homes built long before 1978.

New Rochelle

Many colonials, Tudors, capes, and multi-family properties were built between the 1920s and 1960s.

White Plains

Neighborhoods including Highlands, Gedney Farms, and North White Plains contain many older homes that could be impacted by future regulations.

Mamaroneck

Numerous homes were constructed during the post-war housing boom and may warrant review if future requirements are adopted.

Katonah, Lewisboro, and Bedford

Many historic homes, farmhouses, and colonials date back to the early 1900s and may contain original painted surfaces.

How Lead Paint Could Affect a Home Sale

If No Hazards Are Found

A completed inspection may provide additional documentation and confidence during the transaction process.

If Lead Hazards Are Identified

Potential areas of concern may include:

• Window trim
• Doors
• Exterior siding
• Porches
• Railings
• Interior woodwork

Depending upon the circumstances, buyers may request:

• Repairs
• Credits
• Price adjustments

Estimated Inspection Costs

Lead paint inspections may cost approximately $300 to $1,000 or more depending upon:

• Property size
• Number of units
• Accessibility
• Scope of testing required

Homeowners should obtain quotes from qualified inspectors and discuss potential tax implications with their accountant or tax advisor.

Potential Impact on Listing Timelines

If future lead paint testing requirements are adopted, homeowners may need to begin preparing earlier in the selling process.

Suggested Timeline

60-90 Days Before Listing

• Meet with a Realtor
• Discuss pricing strategy
• Review property records
• Research inspection requirements

30-60 Days Before Listing

• Address maintenance concerns
• Gather documentation
• Prepare disclosures

Before Accepting an Offer

• Verify compliance requirements
• Consult legal counsel if necessary
• Ensure documentation is available

Lead Paint and Health Considerations

Lead exposure can present health risks, particularly for:

• Young children
• Pregnant women
• Individuals with compromised immune systems

Lead paint may be found beneath multiple layers of paint in:

• Window frames
• Door casings
• Exterior trim
• Older porches and decks

Additional Seller Documentation Buyers Often Review

• Property Condition Disclosure Statements
• Building permits
• Certificate of Occupancy records
• Well and septic records (where applicable)
• Smoke and carbon monoxide detector compliance
• Prior inspection reports

How Future Regulations Could Affect Home Values

Most real estate professionals believe that transparency and preparation generally help facilitate smoother transactions.

If lead paint testing requirements are eventually adopted:

• Prepared homes may attract greater buyer confidence.
• Documentation may help reduce transaction delays.
• Early planning may help avoid last-minute negotiations.

Tips for Homeowners Considering Selling in 2027 and Beyond

Start Preparing Early

Waiting until a buyer is found can create unnecessary stress and delays.

Gather Documentation

• Property surveys
• Permit history
• Tax records
• Inspection reports
• Maintenance records

Work With Local Professionals

A knowledgeable local Realtor, attorney, home inspector, and title professional can help you understand evolving requirements and market expectations.

Westchester County Market Perspective

Communities including New Rochelle, White Plains, Mamaroneck, Rye, Larchmont, Katonah, Bedford, and Lewisboro contain many homes built before 1978. As a result, any future lead paint testing legislation could be especially relevant for homeowners throughout the region.

The best approach is preparation. Staying informed about potential regulatory changes can help homeowners avoid surprises and position their property for a smoother sale when the time comes.
