Garage conversions
Turn an underused garage into a home by understanding what can be retained and what needs to change. Uni Construction helps homeowners evaluate the existing space, develop a workable residential layout, and coordinate the documents and construction scope.
ADU GARAGE CONVERSIONS
Our Promise To You

A garage was designed for a different purpose than a dwelling. Its walls and roof may give the impression that most of the work is complete, but the floor, enclosure, structure, moisture protection, and systems still need evaluation. The useful comparison is the full conversion scope against other realistic options.
Collect available permit records and drawings, then compare them with current conditions. The design should address both the future resident and the main household: access, privacy, storage, laundry, utilities, and the practical effect of losing the original garage use.
Measure the space, locate openings, record visible construction and services, and review available permits. Identify concealed or uncertain conditions. Measured drawings should distinguish observed information from assumptions about foundations or framing that have not been verified.
Fit a kitchen, bathroom, living space, sleeping area, and storage into a usable plan. Evaluate floor height, moisture management, insulation, ventilation, and openings as applicable. Avoid planning the interior before understanding whether the existing shell can support it.

Clear, concise answers to your important garage conversion questions.
No. Existing condition, structural work, floor and moisture issues, utility connections, and residential upgrades can materially change the cost. Compare complete scopes on the actual property rather than assuming an existing roof and walls make the conversion inexpensive.
Start by reviewing records and current conditions with the appropriate professionals and authority. Documentation and corrective work may be required. Do not assume that an existing alteration establishes approval for residential use.
Uni Construction’s published project material includes an existing-garage conversion design in Los Angeles. The documented role is design. Share your own property information so the proposed work can be evaluated independently rather than assuming another project’s approval applies.
Ask garage conversion builders to distinguish existing conditions from proposed work. Request a scope covering structural investigation, moisture protection, kitchen and bathroom systems, insulation, openings and finishes. Compare the same scope across proposals, including permit coordination and how concealed conditions will be addressed.
A garage ADU is intended to function as an independent dwelling. To convert a garage into an apartment or convert a garage into a granny flat, first assess the existing structure and develop a residential layout with the required facilities. A sleeping room or finished garage alone does not establish an approved independent home.
