About Property

An extraordinary opportunity awaits at 160 Spring Grove Avenue where years of thoughtful planning meet a rare chance to build with confidence in one of Marin's most coveted settings. Backed by over 2.5 years of entitlement progress and Planning Department approvals, this offering is further elevated by California's SB 450, streamlining the path forward with greater certainty, reduced timelines, and minimized entitlement risk. Set within the scenic beauty of San Anselmo's Ross Valley, the approved plans envision a sophisticated 5-bedroom, 3.5-bath modern Mediterranean residence designed to harmonize timeless architecture with today's demand for light, flow, and connection to nature. This is more than land; it's a vision, ready to be realized. The homesite is a study in balance and intention. Nestled among majestic redwoods and oriented to capture sweeping mountain vistas, the design preserves the integrity of the natural landscape while maximizing privacy, usability, and views. Carefully integrated into the hillside, the project meets all setback requirements and includes thoughtful enhancements for access, safety, and neighborhood compatibility supported by a shade study confirming minimal impact on surrounding homes. Inside, the future residence is conceived for both elevated entertaining and everyday living. A grand, light-filled great room opens seamlessly to expansive outdoor spaces, including a view-facing balcony ideal for al fresco dining or quiet mornings above the valley. Spa-inspired bathrooms, flexible living areas, and a refined material palette create a home that feels both luxurious and livable. Built with performance in mind, the design incorporates prefabricated structural insulated panels for superior energy efficiency, along with durable, low-maintenance finishes and a fully electric system with radiant heating. The result is a residence that is as sustainable as it is beautiful crafted for long-term comfort and modern living. All of this, just moments from the charm and vibrancy of downtown San Anselmo, where boutique shopping, cafes, and restaurants create a true sense of community. At 160 Spring Grove Avenue, the heavy lifting has been done. What remains is the opportunity to build, to create, and to bring a remarkable vision to life in one of Marin's most special locations.

Ron represented me twice in recent years on the listing and sale of two investment properties. His vast knowledge and experience in real estate made for trouble free and expedient transactions. Ron’s communication and negotiation skills are top notch. Highlighting Ron’s genial personality, it was a pleasure to have him represent me.

— Glenn S.

Ron was a tremendous help during an extremely difficult transition for me after living in my house for 36 years.  He went far beyond what I expected in a RE Broker by helping to enhance the appeal of my house and by guiding me through all the challenges that came up from selling a rural property.  And he’s just a genuinely nice guy! His calm attentiveness and deep knowledge made the move bearable when I felt like giving up just from exhaustion. On top of that, he helped me acquire my current house which is so perfect for me during this new chapter of my life. A very happy ending!

Ron Welsh, the owner/broker of Sonoma County Properties Inc., has been nothing less than an angel in disguise when it came to the sale of my grandmothers property.

When my grandmother died at the age of 103, she left her only asset of a country property in Santa Rosa to her four children in equal shares. These are four senior citizen adults that did not typically see eye to eye. Ron was patient, understanding, unflappable, and made the process extremely easy. His experience in real estate transactions was evident and his experience in dealing with multiple obstreperous parties was clearly unmatched.

Ron kept the family apprised of every step in the process and was successful in selling my grandmothers (rather dilapidated) home in just a few days to the satisfaction of all parties. That was no easy feat.

I would highly recommend Ron and his team in any real estate transaction, whether that be buying or selling a home.

— Kathleen Pozzi

I found Ron to be the consummate professional. He is extremely skilled and accomplished at all phases of the sales process. His hard work and negotiating skills were the deciding factor in closing the sale of our home in less than 90 days at 97% of our asking price. That is a real accomplishment, as our home was priced at the upper end of the market where buyers were far and few between.

I would highly recommend Ron’s services for anybody looking to purchase or sell a home in this area.

— mwerneralsco

We were looking for a unique house with character. Ron took the time to understand our needs and was patient with us as we spent many months looking for the right house. He was always available to answer questions or tour properties, and didn’t push us to commit to something that wasn’t right. Ron was a calm, reassuring presence during our search. He knows both the real estate business and the local market. Ron is an experienced advocate you’ll be glad to have in your corner. He is the Realtor we would recommend to friends and family.

— MF Warren

We were able to hit our target date for listing and Ron had us priced right to get multiple offers within 48 hours. From that we were able to choose a strong buyer and close in under 3 weeks, still in October. What had seemed an impossible dream became our new reality thanks to Ron’s experience and ability to get us connected to the right people and complete our pre-sale tasks. Aside from all this Ron is simply a great person to know and work with. He is hands on (literally helping me tear down a false wall the tenants had erected) and was constantly extending offers to help in any way he can with the contractor and appliance deliveries. I strongly recommend Ron to anyone looking for a top quality real estate experience.

— Kevin E.

Ron has helped our family members buy two homes and sell another. I’ve also recommended him to several friends over the years – something I only do when I really trust someone to take good care of them. Everyone has really enjoyed working with him and they’ve become repeat customers of his now too. He knows Sonoma County so well and has a great mellow personality. except when you need him to really rally for you during price negotiations – the perfect combo you want in a realtor!

— Kelley K.

Ron negotiated our very challenging deal with multiple transacations and deadlines. This was definately the kind of situation the required experience. He went the extra mile to ensure that both our real estate sale and purchase closed on time. This was such a tricky process, I really don’t think it would have happened without Ron there to help us through!

— Nick S.

Ron Welsh, has been our real estate the past few months, He has conducted himself, very professional, has been very sincere in our needs of real estate. Dealing with past agents some were not very reliable, Ron was always on time with appointments. It has been a pleasure working with him.

— David & Linda R.

I’ve had 2 purchase and one sell experiences in my life so far; hands down Ron Welsh / Sonoma County Properties was best real estate experience I’ve had to date.

In the end, I felt like Ron was really on my side, advocating my position at every step. Thanks to him, our project is well on its way and we should have our new home for the next holidays.
