Meet the law firm built for rental property owners

For the better part of three decades, Bornstein Law has managed landlord-tenant relationships and handled complex real estate litigation throughout the Bay Area with a strong preference to resolve disputes as quickly and inexpensively as possible, taking into account time, risk, and attorneys fees.



When it comes to landlord-tenant law, not all attorneys are created equal.

If you are vetting attorneys, a perfectly reasonable question to ask is: do you handle landlord-tenant relationships on a daily basis? If the answer is no, you should ask the attorney to kindly refer you to someone whose core practice is specializing in this complex and ever-changing area of law.

Landlording rules are very balkanized. We have state law, a patchwork of local ordinances, and an overlay of residual tenant protections from COVID. Now is not the time to rely on legal advice from a cousin who practices personal injury law.

We think smartly and strategically about your real estate investments.
Bornstein Law approaches cases from the perspective of a business decision. As investors ourselves, your bottom line is always top of mind and the advice we impart is what we would do ourselves – we put ourselves in your shoes.

Frank, candid advice removed from the emotional fray.
We allow clients the opportunity to emote and then we get laser-focused on accomplishing the goal at hand. Being forthright and blunt, we found, is the best way to approach difficult rental relationships. When there is no easy solution, we will tell you. You’ll find our direct and sensible communication to be valuable in our dialogue with tenants or their counsel, and this sometimes requires “thick skin” in informing residents that it is time to make a chapter change in their housing.

We know what we know, and we know what we don't know.
Law has become very niche-specific and our firm refuses to spread ourselves too thinly. Managing landlord-tenant relationships is what we do on a daily basis and when a matter migrates into another area of law, we will refer you to an expert in their respective field.

Our goal is never to enlarge a dispute but resolve it as quickly and inexpensively as possible, taking into account time, risk, and attorneys' fees.
Although we are not doctors, we take the Hippocratic Oath to do no harm. When a dispute is enlarged, it costs our clients more money and we don’t like that. It’s analogous to a game of chess. We like to play five-minute chess, not a four-hour game of chess. Unlike some attorneys who feed their families by being mired in long, protracted disputes and dragging the matter on, our firm abhors a lengthy conflict.

Lowering the temperature of disputes and avoiding court if at all possible.
Litigation is not like a Warriors or an A’s game when one side wins and one side loses. It can be a costly and harrowing endeavor. Our strong preference is to resolve a matter out of court by having a leveraged discussion with the tenant or their counsel.

Zealous advocacy in a difficult set of circumstances.
We are human and sometimes, it’s hard not to be empathetic to the other party, but as professionals, we remain steadfast in accomplishing the goal you hired us to do.


We are deeply committed to educating our community about a complicated regulatory regime.

Landlording is fraught with risks and small property owners are especially vulnerable to making costly mistakes that are not compliant with a minefield of new rules.
