Who We Are
Management With Purpose.
Harborstone Management provides thoughtful HOA management services designed to protect property values, strengthen communities, and make board service easier.
We are deliberately small. That means a named manager who knows your buildings, your budget, and your board — not a call center reading from a script. Experienced leadership, transparent financial management, responsive communication, and proactive maintenance are the foundation of everything we do.
- Personalized service
- Experienced leadership
- Transparent financials
- Proactive maintenance
What We Do
Full-Service HOA Management, One Accountable Team
Four disciplines that keep a community association healthy — handled by people who know your property by name.
Financial Management
Clear, accurate financial management designed to give boards and owners a better understanding of where their money is going.
Maintenance & Vendor Management
We coordinate repairs, preventive maintenance, vendors, inspections, and projects so issues don't fall through the cracks.
Compliance & Risk Management
We help communities stay compliant with governing documents, regulations, and insurance requirements to reduce risk.
Why Harborstone
The Difference Is In How We Answer.
Boards leave large management companies for the same reasons: they stopped hearing back. Harborstone was built to be the opposite — accountable, transparent, and genuinely invested in your community.
Responsive Service
Your management company should actually answer the phone — and know what's happening when you call.
Transparent Financials
Clear reporting and organized financial management help boards make confident decisions.
Proactive Management
We identify issues early, coordinate reliable vendors, and help protect your community and property.
Modern Technology
We use today's technology to make communication, reporting, and management more efficient and accessible.
Our Commitment
Your Community.
Our Commitment.
Whether you're a self-managed board or an association looking for a management partner, Harborstone is built around one simple idea:
Better management creates better communities.

Where We Work
Six Counties. One Bay.
Harborstone serves community associations on both sides of the Bay — from the Marin headlands to the Napa Valley. Local knowledge of climate, construction, and code is not a nice-to-have. It's how problems get solved before they get expensive.
