Garage Conversion ADUs in Sun Valley
When an existing garage leads the ADU plan on a Sun Valley lot, what its slab, walls and roof must prove, and how LADBS reviews egress and fire separation.
A sound detached garage behind a Sun Valley house is where our ADU construction work begins, with its conversion as the first option we price. The shell is already standing, so new foundation and long trenches may not be needed. That only holds if the slab, framing and roof test well, so the conversion is still drawn next to the other three types, with the cost of each shown.
What the garage has to prove
The slab is checked for cracks, settlement and moisture coming up from below. We measure ceiling height against what a habitable room needs, and look at whether the walls bear on a continuous footing. Rafters, ties and the roof covering are inspected for size, sag and leaks. A failure in any of these narrows the cost gap with a new detached unit, and the comparison is redrawn with that in mind. Once the structure checks out, the drawings add wall and roof insulation, an egress window for the bedroom and new framing to close the old door opening.
Heat, power and plan check
Under hard inland sun, an old garage roof with no insulation leaves the room hot, so roof insulation and ventilation are planned at the start. A new kitchen and a heat pump may push the electrical panel past its rating, which is priced before the type is chosen. Conversions in Sun Valley are reviewed by LADBS for egress, fire separation and energy compliance, and the same office handles North Hollywood, Arleta, Valley Village, Lake View Terrace and Pacoima. Each of those lots gets the same garage tests before a conversion is drawn.
