Client Testimonials


Working with Brick Work gives me transparency into precisely what you can potentially build on the site, if its located in an opportunity zone, and who you need to contact in the local government. The first thing I do when I am working on a potential deal is to run it thru Brick Work. Recently they helped me closed on a $35,000,000 deal in south Los Angeles, and I will continue to use them in the future.

Provide answers to questions that people ask the most.

How do you determine the buildable square feet of my lot?

Every city has its own method in determining maximum buildable square footage. Some cities like LA City use Floor Area Ratio (FAR), while some cities use Parcel Coverage.

Are hillside properties SB9 qualified?
Yes. Hillside Properties can still be qualified for SB9. However we cannot accurately determine Maximum square footage without a slope band analysis.
Do all cities allow for flag lots?
No. Not all cities allow for flag lots.
Does the owner occupancy requirement apply to all SB9 properties?
Only Lot Splits require owner occupancy.
Are the new units required to be under rent control?
If it was being rented before and built before 1979 it would be affected by rent stabilization, but if it was owner occupied and you are just building a new unit, then it would not be affected by rent stabilization.
