ADU Construction in South Pasadena
ADU planning in South Pasadena follows the same steps we use in Alhambra, Pasadena and San Marino: measure, compare each unit type, trace utilities, draw.
Alhambra, Pasadena, San Marino, San Gabriel, Eagle Rock and Monterey Park all lie near South Pasadena, and an ADU project in any of those places moves through one sequence with us. We measure the parcel, set each of the four ADU types against its setbacks, trace the sewer and power, then draw the option that fits. From one city to the next, only the reviewing office and the conditions on the lot change.
The same steps on every parcel
The visit produces a measured sketch showing the house, the driveway, trees worth keeping and the lot lines. Onto that sketch go four layouts, from a JADU tucked into existing rooms to a converted garage, a unit built against a house wall and a cottage standing on its own. For each one we note the privacy it gives, how far its drain must travel to reach the main line and whether the panel can carry another kitchen. Seeing them side by side lets a South Pasadena owner pick with the tradeoffs in plain view, before any drawing is paid for.
What shifts once the city is South Pasadena
Plan check and inspections for a South Pasadena unit run through the City of South Pasadena, which measures the set against state ADU law plus the city zoning rules. We answer its comments directly and keep the corrected sheets in step. Inland suburban parcels see hard sun and dry wind, so the materials list leans toward a reflective roof, sealed attic vents and glazing coated to cut solar heat. If the lot slopes, the footings step with the ground and the drainage plan sends roof water clear of both buildings.
