Lot Splits to Maximize Your Property Value

Take advantage of California’s new Lot Split Law to unleash your property’s value.

Creating another legal property adds $400,000-$900,000+ to your property value in just one year.

Why do a lot split:

  • Increase property value by ~25% without a tax increase
  • Create an additional real estate asset that can be developed and sold separately
  • Increase what you can build on your land (up to 4 houses)
  • Enhance estate planning & diversify assets
  • Get access to more cash

How to Lot Split Under SB9

Harf, Sonoma Business Family

Our property didn’t meet the minimum lot size for a traditional lot split but then we did SB9 and created a $1,000,000 parcel.

Don, Novato Business Family

I enthusiastically recommend Riechers Engineering. They recently completed an SB-9 lot split for our property. This is a complicated process, and I wouldn’t have wanted to do it myself. They navigated regulatory and technical obstacles, completing the job on time and on budget.

May, Napa Business Family

I hope you decide to go forward with the lot split. We have seen our property value increase. You will be in good hands with Mr. Riechers.

Steve, Corte Madera Business Family

We wouldn’t have been able to build on the steep lot. But because we did the lot split, we can build 2,000 sq ft. Highly recommend this investment.

Jerry and Patti, Napa Business Family

We had the privilege of working with Riechers Engineering. They completed the lot split with speed, met all city requirements and answered all our questions. Peter’s knowledge was exceptionally apropos for the job at hand. We were grateful that this project was in excellent hands.

Cynthia, Contra Costa Co Business Family

It's been great working with Riechers Engineering throughout this process. We were previously unaware of the opportunity and your company's expertise handled all the complexities.

CALIFORNIA’S NEW SB9 LAW

Senate Bill 9- California’s Lot Split Law explained

What is SB9?

A new law that passed in 2021 that empowers homeowners to increase the value of their parcel by splitting it into two legal properties.

Who can benefit?

Specific homeowners whose property is zoned "Single Family Residential" in the urban areas of California and meets specific environmental criteria.

What’s the rush?

Many jurisdictions are already imposing restrictions on the state law. NIMBY groups are petitioning to remove SB9 altogether on the next ballot. The window to act on this unique opportunity may be limited.

Client involvement is minimal. We take care of every process so that our client needs to do as little as possible. 

Client involvement includes: sign application documents, notarize affidavit, approve parcel line we draw up, sign the final parcel map, pay your upcoming property taxes, send payment to Riechers Engineering. From start to finish, this process will only take 3 hours or less of your time in total.

Your lot split is 100% guaranteed when you work with us. If we are unsuccessful in creating your second parcel for any reason, you will owe nothing for our time or costs incurred on your project. It is that simple: no fine print, no hidden fees. No upfront deposit for the project. We want to make this process a “no brainer” for our clients, so we’ve taken all the risk out of it for you.

The lot split price varies project to project as well as by jurisdiction. Every jurisdiction has different requirements, application fees and planning department fees. Each project has a differing level of complexity and risk. 

Here is a general cost breakdown for the lot split, all of which is included in our fee, handled by us, and GUARANTEED by our firm (e.g. if we’re unsuccessful, you don’t pay). Lastly, please note that we will agree upon a fixed price before commencing your project. Even if costs are higher than we expect, we will not raise your price at the end.

  • Boundary survey $3,500 – $12,000

The county charges T&M with a modest deposit, then calls for replenishment whenever the deposit account runs out.  There is no limit on what they could charge

The lot split requires a whole lot of work: 12 months of application prep, submission and engagement with the planning departments, organizing and performing surveys and reports, finding specialists to complete the various requirements. Because we have in-house engineers, surveyors and draftspeople, we have lower costs than if you were to hire out professionals yourself. We are also California’s leading experts in SB9 with over 50 lot split applications throughout California. We have already done all the necessary research and know how to avoid the most common pitfalls of SB9 applications. You can spend a year of your time and perhaps more than $60,000 doing it yourself, or you can hire us to do everything for you, source professionals, and take on 100% of the risk.

No, creating your two legal parcels does not require an architect.  If you choose to build on the new lot, that is when you would hire an architect. We will contact your utility companies and request “can and will serve letters” for your new parcel, however our company does not pay for the installation of new utility services.
