ADU Construction in Alhambra
When an ADU is the right first project on an Alhambra lot, how the unit types compare on an urban parcel, and how the city reviews the plans.
When the main house needs no changes and the missing piece is a second, self-contained home on the property, ADU construction is the first job to plan in Alhambra. A new unit brings its own kitchen, bathroom and front door without reworking the rooms you live in now. On an urban lot, the open question is which of the four types the parcel can hold.
Weighing the types on an urban lot
A detached unit needs open ground behind the house once setbacks and the required gap from the main dwelling are subtracted, so a shallow rear yard can rule it out. A garage conversion keeps an existing footprint, provided the slab, framing and roof can be brought up to current code. An attached unit joins the house along one wall, which keeps pipe and wire runs short. A JADU is formed from rooms inside the home and gains a separate entrance. We draw each candidate to scale on your parcel, so privacy, yard space and construction scope can be weighed before design begins.
City review and hookups in Alhambra
Alhambra runs its own plan check, and the reviewer measures ADU drawings against state law and the city's zoning code. Our submittal includes the structural and energy calculations, and each comment is answered on a revised sheet. Sewer and water connections are planned to the city's requirements, and the panel is sized for the added load before the electrical layout is drawn. Inspections follow the stages of the build, from footings to framing to insulation, ending with the final visit that clears the unit for use.
