San Francisco Real Estate Investing: Rent Control Traps Every Investor Must Understand

Show summary

In this episode, Dzintars Grinfelds shares insights from his diverse experiences as a professional bowler, real estate investor, and digital marketing expert. Discover how dedication, social media leverage, and strategic property management can build wealth across different arenas.

Key takeaways

  • San Francisco rent control applies to duplexes and larger (2+ units); single-family homes are exempt from rent control unless the tenant moved in before 1996 — investors who miss that date can unknowingly buy a rent-controlled single-family property.
  • In rent-controlled units, annual allowable rent increases have been capped around 1.5% for the last three years; capital improvements (new roofs, patios, paint jobs that add real value, not cosmetic 'lipstick on a pig') can justify additional increases.
  • For non-rent-controlled single-family homes, Grinfelds raised rent up to the California rate cap, about 10% last year, on two properties that hadn't had an increase since the tenants moved in.
  • Noe Valley and the Castro area in San Francisco have been strong rental submarkets; tech shuttle bus stops near his properties in the late 1990s/2000s tech boom attracted tech VPs and senior management as tenants, pushing rents up.
  • Value-add in older (often Victorian, one built in 1908) San Francisco properties means custom tile work, backsplashes, period-appropriate finishes, and preserving original details (e.g., stripping paint to reveal original redwood railings) rather than standard cream-wall, white-trim units.
  • He works with one broker/family friend of 25 years who sources deals off Craigslist, Redfin, etc., and who also vets tenants for fit within a duplex/triplex, not just individual creditworthiness.
  • He prefers buying vacant properties when possible so he can control renovation and tenant placement, though he acknowledges tenant-occupied purchases offer instant income if the existing tenant situation is known and workable.
  • He treats property management as hands-on: inspecting issues like a leaking washer himself to diagnose appliance vs. hose problems rather than just dispatching a contractor, which he says most property managers skip by only 'taking phone calls and distributing workload.'

“After if anyone moved in after 1996 a single-family home doesn't have rent control. But there are investors who jump into it and don't know that date so they may be investing in a building that has someone rent controlled... it may backfire on their investment.”

“I consider myself an investor and property manager... I see it as property managers nowadays have it too easy. They just take phone calls and distribute the workload. Whereas if I take a call from somebody, I'm on site.”

Questions answered in this episode

Does rent control apply to single-family homes in San Francisco?

No, single-family homes in San Francisco are generally exempt from rent control, with one major exception: if the tenant moved in before 1996, the property can still be subject to rent control even though it's a single-family home. Investors who don't check this date can unknowingly buy into a rent-controlled situation.

How much can landlords raise rent on rent-controlled units in San Francisco?

According to Dzintars Grinfelds, the city sets an annual maximum increase, which has been about 1.5% for the last three years. Landlords can add more if they make a genuine capital improvement, like a new roof, patio, or paint job that adds real value, not just cosmetic fixes.

What neighborhoods in San Francisco are good for rental investing?

Grinfelds points to Noe Valley and the surrounding Castro area as consistent hotbeds for families and demand, noting it's effectively the heart of the city even though downtown is off to the northeast side. Tech shuttle bus stops near these properties during the tech boom also drove up demand from well-paid tech workers.

How did Grinfelds find his investment deals?

He relies on one broker his family has worked with for 25 years, who is constantly monitoring Craigslist, Redfin, and other listing sites. The broker also helps vet tenants, assessing not just individual tenant quality but how well a tenant will mesh with other tenants in a duplex or triplex.

What value-add improvements work well in older San Francisco properties?

He focuses on period-appropriate details rather than standard cream-wall, white-trim finishes: custom tile work in bathrooms, backsplashes, nice lighting, and preserving original architectural elements. On his own 1908 Victorian, he stripped old paint to reveal original redwood railings as part of a remodel.

Should investors buy rental property vacant or tenant-occupied?

Grinfelds says he'd prefer vacant properties going forward because it lets him control renovations and maintain his family's standard of finish. He acknowledges a tenant-occupied purchase offers instant income, but warns it depends heavily on who that tenant is and their rent-control status.

Dzintars is welcome to the show.

Dzintars Grinfelds (02:38)

Thanks for having me. Thanks for your invite.

Dylan Silver (02:40)

Now you’ve competed in multiple different arenas, active professional bowler, worked around major brands and have a rental portfolio in a very hot and competitive market. What mindset carries across all three worlds?

Dzintars Grinfelds (02:54)

I have to say one is dedication and competing for success. I’m always gonna be a competitor. I am always gonna be one to try to be better day by day. So yes, that applies to bowling because obviously I’m competing for money and titles every single time I’m out there. But as you said, in the kind of market that we have here in San Francisco, to be able to essentially argue for the rents that we are getting from our…

and our tenants, we have to give very hands-on services. We have to give exceptional service to everybody. So they do go hand-in-hand, the competitive aspect and then what I apply to people because no matter what, I have to be among the best.

Dylan Silver (03:36)

Do you see any advantages to being able to be active in these three worlds where you might actually reap a lesson from the social media world that’s helpful in bowling or vice versa?

Dzintars Grinfelds (03:50)

⁓ Certainly for myself, it’s using the social media background to promote my own brand as I’m now sponsored by three great companies. I have to promote them, promote myself because that all works together, of course. But having the experiences I did working in sports where I was in digital marketing and social media, but really what that also meant was I got to play with a lot of the new marketing tools that came out.

So I got to adapt ⁓ a lot of things for our business in like just creating digital receipts, how I can use ⁓ task management programs to keep ourselves ⁓ in check, make sure we’re on time, get projects lined up and done ⁓ in good order.

Dylan Silver (04:32)

Now, San Francisco and the greater San Francisco area, for folks who may not be investing in San Fran, do you have any specific neighborhoods that you like to look at deals or evaluate deals in in San Francisco?

Dzintars Grinfelds (04:46)

I appreciate the pause, we definitely don’t call it San Fran. ⁓ So, yeah, within San Francisco, there are pockets that are consistent hotbeds, and I am very lucky that our investments are in one of them. That’s Noe Valley.

Dylan Silver (04:50)

you

Dzintars Grinfelds (05:49)

It’s essentially the heart of San Francisco. Many people don’t know, but downtown is actually off to one side, northeast side. ⁓ Noe Valley, Castro, everything around

These neighborhoods are consistent for families, beautiful weather. In the late 1990s and 2000s with the tech boom, we also got incredibly lucky as investors where the ⁓ tech buses decided to set up shop around our properties. We had stops in front of at least three quarters of our properties. And that meant all of sudden we had

tech VPs, senior management coming in. So of course that affects the rent too, where there’s high demand. And as I said earlier, we’ve always had a family philosophy of having a certain level of class in what we do and what we provide. That just meant that we were bringing in people that expected more too. So rents went up for us, which was ⁓ truly beneficial, but at same time we had to up our game to match that.

Dylan Silver (06:53)

Walk me through what some of that value add looks like.

Dzintars Grinfelds (06:56)

⁓ Even showing ⁓ behind me, detail. ⁓ We really do care about adding more than just cream walls, ⁓ a white trim, know, the whole standard ⁓ unit look, right? ⁓ Of course we keep things pretty clean and basic, but we add a lot of touches like custom tile work in the bathrooms, backsplashes.

⁓ We try to make sure that we have ⁓ views of the city and things are kept tidy so that way when someone walks into a unit they can see like, wow, this is well maintained. ⁓ Nice ornaments, nice lighting. Even, we go shop at other places, not just Lowe’s. And Home Depot, not that they’re wrong. I love buying from Lowe’s as much as anybody.

As we mentioned earlier, I use apps where I get discounts off of Lowe’s and extra cash back. But what matters most is finding things that are true to the periods because a lot of our homes are Victorian.

Dylan Silver (08:01)

Now, ⁓ when you’re looking at deals, are you looking on market, off market? Do you have ⁓ broker relationships that have been fruitful for you? How do you find deals?

Dzintars Grinfelds (08:14)

We’re very lucky to have one broker we’ve worked with for 25 years and he is among those that is constantly on Craigslist and Redfin and all the sites. He’s probably one of the most prolific as well and he has been for all that time. So that just means he is truly among the best. And the best part about that relationship isn’t just that he is essentially a family friend and part of our family.

You can tell from his experience that he has that keen ability to sniff out BS from people. He can really tell who will be a good tenant. He will tell you not just if that individual tenant is good, but if they work well with the rest of the duplexes or triplexes. Because there are people that just are happy to bring in the young techie who is willing to pay a lot in rent.

but they won’t mesh well with the senior tenant down below. Now, we’ve had those kind of circumstances before, ⁓ but now having someone with his experience is just invaluable.

Dylan Silver (09:15)

So he’s not only finding and sourcing these properties, he’s also property manager.

Dzintars Grinfelds (09:18)

Thankfully, that’s where we take over. He will not be hands-on. But ⁓ I have three generations worth of experience doing all the hands-on work. I know that I consider myself an investor and property manager. I live in this space where people see it as a weird overlap. But I see it as property managers nowadays have it too easy. They just take phone calls and distribute the workload. Whereas if I take a call from somebody, I’m on site.

Dylan Silver (09:30)

Mm-hmm.

Yeah.

Dzintars Grinfelds (09:44)

and I’m analyzing what’s going on, let’s say it’s a ⁓ washer, clothes washer, that they say has sprung a leak, they don’t know, the tenant typically doesn’t know what it is that’s going on. And if I can get on site and say, well, clearly it’s coming from the appliance, I see it’s rusted out, therefore I need a new

It’s coming from the appliance, it’s coming from this one area within a washer, you know what, that’s workable. If it’s coming from the hose, I could replace the hose myself.

Having the layers of knowledge that I do is really a benefit that I think a lot of people are missing when they’re in my space.

Dylan Silver (10:53)

Now, do you prefer to be purchasing properties that are tenant occupied or vacant?

Dzintars Grinfelds (10:59)

If I was to do another purchase, I mean, probably not in the cards because I’m gonna have actually remodels coming up, probably within the next 10, 20 years, ⁓ I would much prefer something vacant. I did just make a purchase for my own new house. It will be my personal property and… ⁓

Vacant because like I said before I really do prefer keeping with our family tradition of giving it class ⁓ Giving it the extra bit of elegance here and there ⁓ I Can understand that people would want to purchase with a tenant because that’s instant income, but it depends on who that tenant is too

And in San Francisco, there are a lot of laws you have to navigate around that if for example if they were in the property before 1996 Even though it’s single-family home this rent control

After if anyone moved in after 1996 a single-family home doesn’t have rent control But there are investors who jump into it and don’t know that date so they may be investing in a building that has someone rent controlled which I’m in favor of but It may backfire on their investment

Dylan Silver (12:03)

for sure, for sure. You mentioned earlier some remodels. Are you currently active doing value add in that capacity remodeling?

Dzintars Grinfelds (12:11)

Absolutely, like I said, my own property, of course, ⁓ get to have fun with that project because it was one that was last repainted in the 1970s. Quite literally, they did all one shade of white throughout the entire house, except for the hand railing, which it is an eight inch round hand railing. It was all black and I scraped a little paint away and we found beautiful, original old redwood, like original to the house.

from the 19, I believe it was built 1908. do those little bits of work and it just brings out so much more. But like you said, it’s value added because we’re finding these kinds of details. I absolutely do think that these, especially here in San Francisco where people are willing to spend a little bit more for a comfortable life, they look for those things.

Dylan Silver (12:59)

Now, it sounds like the management of these properties in a long-term hold capacity is really where you’re building your wealth. And so when we talk about successful property management, what are the things that come to mind?

Dzintars Grinfelds (13:16)

⁓ Client care, for sure. ⁓ And that’s always going to be the most difficult one because I’ve told other podcasts, other friends that are interested or just ⁓ other students.

Not everyone’s easy handle, but you have to have that client and customer background to be able to manage that. ⁓ Knowledge and a very general knowledge of everything. I’m never going to say I’m an electrician or a plumber, but I certainly know the science behind it. I know how things work. And to be frank, there are plenty of people that are hopping onto apps such as Thumbtack.

I think one’s called Houzz, there’s Yelp. Everyone can create a new business now and I know that the metrics and data says, excuse me, the data says that there’s a lot of people now taking on blue collar jobs like plumbing and electrician, being electricians, because they can own their own business, which is fantastic. But they don’t carry some of knowledge that some of the people that have been in the trade 30 years do. So I have to watch over them a lot.

Dylan Silver (14:18)

Sure.

And I think that there are a lot of people who, like you mentioned, don’t know where to turn to. And a reliable electrician, a reliable HVAC person, a reliable contractor, handyman, what have you, these can be some of the most valuable people, not just in a long-term hold, but in a short-term rental, right? And anytime you’re managing tenants or turnover, this is huge. What’s your thought on…

rent increases? Is that something that you try to shoot for periodically or every couple of years? What goes into that arithmetic?

Dzintars Grinfelds (14:53)

⁓ So I’ll kind of separate that in two different ways here within San Francisco. ⁓ We are a rent controlled city

and the rent control only applies to duplexes plus. So two unit, three unit. The exception being single family homes before 1996. So that means that with everything that’s rent controlled in San Francisco, it’s incredibly easy. They tell us this is the number this year. That’s your maximum for the last

Three years now, it’s been 1.5%. Done. There are additions I can make if I make a capital improvement to the property, which means something that truly adds to the ⁓ value of people living there. New roofs, new patios, ⁓ paint jobs, but even then it needs to be something within reason and something that truly adds to the property. It’s not just lipstick on a pig. ⁓

So there are other ways to up the rent, but everything is, like I said, controlled and watched within the city. Now, single family homes, I can increase as much as I’d like up to the California rate, which I believe I did. ⁓ It was 10 % last year, and I did that for two properties. But that’s because we had not increased their rent for, frankly, since they had moved in, which was fine.

I’m always watching the numbers. I always do ⁓ annual charts to make sure that our budget’s on par. Plenty of the properties are ⁓ working well within their range, and I’m not worried about having to crunch, ⁓ add rent to get more out of them. But because this year our insurances went up 25 % across the board, I had to send a letter to these tenants at single family homes and say, you know what, it’s just time.

And thankfully, because we have this rapport with our tenants, they said, not a problem.

Dylan Silver (17:23)

We are coming up on time here, Dzintars. Any ⁓ new projects that you’re working on.

Dzintars Grinfelds (17:28)
