San Gabriel Valley
Before you sell, build, or split, find out what your San Gabriel Valley land can do.
What We Do
Services built
for the SGV
From one ADU to a multi-unit project, the advice starts from the same record: what has been approved, built, or stalled in your city.
Lot Feasibility
What your lot can hold under its zoning, state law and the density bonus, read against what your city has actually approved nearby. A plain answer before you spend on design.
ADU Consulting
End-to-end ADU services: feasibility analysis, design coordination, permitting, and construction management, from garage conversions to detached units.
Development & Project Management
Ground-up development, lot splits, and infill housing for the SGV. We coordinate the architect, consultants and the city from feasibility through completion.
Rules & Law, Explained
City zoning and ADU rules, state housing law, and real SGV projects, written for owners deciding what to do with their land.

About SGV Housing
Built on the
public record
SGV Housing helps San Gabriel Valley landowners work out what they can do with their land: sell, build, split, or hold. It is an advisory, not a brokerage: we don’t list, buy, or sell property for clients.
Independent
No listing to win and no commission on your sale. The read on your lot is the same whether you build, sell, or hold.
Grounded in the record
Every project page cites the record it came from and the date it was last checked; every article lists its sources. Advice draws on the same sources.
Full-cycle development
From initial feasibility analysis through design, permitting, and construction management, we guide projects from concept to completion.
Housing for more people
We believe the SGV needs more housing options. ADUs, lot splits, and infill development are tools we actively champion — creating rental income for owners and more homes for the community.
FAQ
Common
questions
Especially around ADUs, rent control, and what's possible on your property.
Yes. One ADU and one JADU (Junior ADU) may be built on any lot with an existing or planned single-family home. ADUs can be created through ground-up construction, a garage conversion, or a conversion of part of the existing residence.
Total area for a detached ADU may not exceed 1,200 sq ft. An ADU attached to the main residence is capped at 50% of the size of the home.
Ground-up ADUs require a 4-foot setback from the side and rear yard. Garage conversions within the existing structure footprint typically have more flexibility — contact us for a site-specific analysis.
Yes. If there is no prior building permit on record for the garage, you will need to apply for a new construction permit. If the existing garage was previously permitted, the conversion would be processed as an alteration permit. Either way, the ADU must comply with current building code.
In short — yes, if the property is in the City of Los Angeles. Adding an ADU transforms a single-family residence into a duplex or triplex, making the property subject to rent stabilization ordinances. We have a detailed flow chart on this topic and recommend consulting a real estate attorney before proceeding.
Yes. For multifamily-zoned properties, two detached ADUs can be added to the site, and portions of the existing structure can also be converted into ADUs.
If the property is within half a mile of public transportation, the single parking space requirement is waived. Two parking spaces for the existing residence must be maintained unless a garage or carport is demolished or converted to create the ADU. Replacement spaces can be uncovered, tandem, and/or within setbacks.
No. SGV Housing is an advisory, not a brokerage — we don't list, buy, or sell property for clients. We can tell you what a lot can hold and what the city has approved nearby, so you go into a sale or purchase knowing that.
