Project Overview

Project: South Los Angeles Garage Conversion

Location: South Los Angeles, CA

ADU Type: Detached Garage Conversion

Scope: 1 Bedroom / 1 Bathroom

Project Goal: Rental Unit

Key Challenge: Existing Framing Issues

Documented Result: Framing and Rough Mechanical Stages


The project involved converting an existing detached garage into a 1-bedroom, 1-bathroom residential unit. The client's goal was to transform the existing space into an additional rental unit on the property.

Turning an Existing Garage Into a Rental Unit

The project focused on giving an existing detached structure a new residential purpose.


Rather than beginning with ground-up construction, the project used the existing garage as the foundation for a 1-bedroom, 1-bathroom rental unit. This meant working with the conditions already present within the structure while adapting it for the intended residential use.

Existing Framing Required Reinforcement

Garage conversions can reveal existing structural conditions that need to be addressed as construction progresses.


For this project, the documented challenge involved issues with the existing framing. The condition required a structural response before the conversion could continue through the documented construction stages.

Reinforcing With Sister Beams & Joists


To address the existing framing issues, the team reinforced the structure using sister beams and joists.


This provided the documented solution to the framing conditions encountered during the garage conversion.

Working With the Existing Structure

The project demonstrates an important difference between ground-up ADU construction and the conversion of an existing structure.


Existing buildings can present conditions that need to be addressed as the project progresses. In this case, the existing framing required reinforcement with sister beams and joists as part of adapting the detached garage for its new residential use.


The project reflects a property-specific approach focused on responding to the actual structural conditions encountered rather than assuming the existing garage could be converted without additional work.

Project Highlights

Detached Garage Conversion

The project involved converting an existing detached garage into residential space.

1 Bedroom / 1 Bathroom

The planned residential configuration included one bedroom and one bathroom.

Rental Unit Goal

The client's objective was to create an additional rental unit on the property.

Existing Framing Challenge

Issues with the garage's existing framing were encountered during the project.

Sister Beams & Joists

The documented solution involved reinforcing the existing framing with sister beams and joists.

Construction Progress Documented

The supplied project assets document the conversion during the framing and rough mechanical stage.

Documenting the Conversion in Progress

The supplied portfolio materials capture the project during active construction rather than presenting it as a completed conversion.


The documented imagery covers the framing and rough mechanical stage, providing a look at the structural and building-system work involved as the existing garage was adapted for residential use.


Because the provided project summary does not state that the conversion was completed, the project is presented according to the documented construction stage rather than making an unsupported completion claim.

Adapting Existing Space Around a Clear Goal

The project began with a clear property objective: convert an existing detached garage into a 1-bedroom, 1-bathroom rental unit.


When framing issues were encountered, the project required reinforcement using sister beams and joists before progressing through the documented framing and rough mechanical stages.


It is an example of how an existing structure may require property-specific construction solutions as it is adapted for a new residential use.
