ADU Construction in San Marino
Serving 91108 and Pasadena, South Pasadena, Alhambra
The lots here are deep and the gardens are mature, which makes an accessory dwelling both easy to place and easy to place badly. In a city that reviews how buildings look, a second unit is a design problem first: what it does to the garden, what it does to the neighbour, and what it does to the composition of a property that has looked settled for eighty years.
Real projects. Real prices.
73 finished remodels published with their final price — nothing hidden.
What our finished LA work actually cost: 27 kitchens ran $23k–$84k, median $50k; 28 bathrooms $28k–$105k, median $38k; 17 whole-home remodels $36k–$440k, median $150k. Real final prices from our own job records, not estimates.
$30,000 A deep navy wall over textured white tile, with a floating walnut vanity and matte black fittings.
$38,000 Emerald shaker cabinetry and brass hardware around a cream range and an apron sink.
$56,000 Marble-look slab walls with matte black fittings and a backlit mirror over an oak vanity.
$75,000 Wood shaker cabinetry under a full-height quartz slab, with a marble-look hall bath.
$238,000 A walnut-fronted quartz island, arched openings, and sage-green stacked tile baths.
$275,000 A broad quartz island, a curved staircase with iron balusters, marble-look baths.
Second units on large San Marino lots
Siting is the whole design
Where the unit sits decides whether both households keep a garden, whether either loses its privacy, and whether the main house still reads as the main house. It is worth several sketches before any of it becomes a floor plan.
Mature trees are not obstacles to be removed
The planting on these lots is often the oldest thing on the property and a large part of its value. We survey it and design around root zones and canopies rather than treating them as site clearance.
Design review, and how to arrive ready
A new structure visible from public view is the committee's business. Drawings that show the proposal in its setting, from the angles people actually see, answer the question the committee is asking — and the approval travels onto the plans that go to the Building Division.
