Adore Homes
Tap a star to rate
Adore Homes has positioned itself as the Bay Area's broadest-reach ADU firm by solving a problem that narrows most competitors: whether an ADU should be prefabricated or built on-site, the firm offers both. This dual capability lets Adore match the construction method to the property constraints rather than forcing every job into one template. The company holds Contractors License #1145340 and Housing and Community Development License #DL1573381, regulatory credentials that indicate state-level registration beyond basic contracting. The firm's Campbell headquarters sits in the heart of Silicon Valley's housing market, and pre-approval status across 25 jurisdictions means you can get an ADU permitted in Santa Clara County, into Sonoma, across Alameda County, into Marin, and through Napa County without needing separate municipal outreach for each city.
The two construction methods available represent a genuine trade-off, and Adore Homes' website articulates both honestly. Prefab manufacturing takes place in a factory, where components are built in controlled conditions, then delivered to the site for crane installation. The advantages are significant: factory-controlled quality, faster on-site assembly (sometimes a matter of days), predictable budgets and timelines, minimal neighborhood disruption, and reduced worker exposure to weather. The downside is that prefab units fit best on relatively straightforward lots. A steeply sloped property, a lot with constrained crane access, or a site with complex utility runs may not accommodate a prefab delivery. Site-built construction happens on the property itself, over months, with greater flexibility for unusual topography, high-end finishes, and custom designs. The trade-off is longer timelines, more weather dependency, greater neighborhood impact during construction, and less predictability on final cost.
The model lineup speaks to Adore's breadth. The Signature A is a studio at 377 square feet with one bathroom, starting around $249,000. The two-bedroom units in the Signature line range from 623 to 800 square feet. The Horizon line offers larger configurations, including two and three-bedroom options from 800 to 1,200 square feet. The Crema and Landmark lines provide mid-range options in the 500 to 700 square foot range. The Heights line goes vertically oriented, with one and two-bedroom units from 765 to 870 square feet. Across the full lineup, pricing runs from about $249,000 for studios up to approximately $395,000 for the largest three-bedroom units. This breadth of options, from tiny studios to spacious three-bedroom units, means different homeowners can find something that fits both their budget and their space needs.
The pricing structure Adore quotes is honest about what you are buying. Starting prices are real prices, though customization, custom finishes, and site-specific work can push a project higher. Choosing upgraded finishes, a different exterior material, or site preparation on a complex lot will add expense. This is more transparent than vague language that obscures the true cost of a real home. Pricing overall suggests that Adore is not the cheapest option in the Bay Area and not the most expensive; the firm is targeting homeowners who value quality and breadth of choice over rock-bottom pricing.
Adore Homes' process is documented in nine steps spanning nine to twelve months. The first step is design: you select a base model and customize it to your needs. The second is discovery, a free remote assessment where the firm determines whether your lot and zoning fit with your ADU ambitions. This early gate is important. A lot in a single-family neighborhood with strict ADU restrictions may not be feasible regardless of how much you want to build, and Adore flags that early rather than spending months pursuing a dead end. The third step is the site walk, where 3D scanning and measurements inform precise placement and utility routing. The fourth is contract review, where you get a detailed all-in price with no surprises itemized. The fifth step is permitting, where Adore handles full permit preparation and municipal submission. The sixth is site preparation: foundation work and utility installation begins on your property. The seventh is installation itself, where a prefab unit is crane-installed in hours or a site-built unit advances through framing, mechanical, and interior phases. The eighth is finishing: utilities are connected, inspections are passed, and any final details are resolved. The ninth is move-in.
Adore breaks the timeline into four phases. Site assessment and permitting take three to five months. Manufacturing takes three months for a prefab unit (or less for site-built, which runs concurrent with permits). Site preparation and installation take one month. On-site completion takes two to three months. This is a realistic timeline for the Bay Area. Compare it to the old way: design delay, design review fight, permitting delays, contractor scheduling delays, weather delay, inspection failures, and the whole thing stretches to eighteen months or more. Adore's structured process and prefab manufacturing bypass some of those delays, though permitting in Palo Alto or Los Gatos or Sonoma still moves at the municipality's pace, not the contractor's.
Geographic reach matters in the Bay Area because you need pre-approval in your specific city or you need a design-build firm that has navigated your city's process before. Adore's list of 25 pre-approval jurisdictions is extensive. Cities and counties served include San Jose, Cupertino, Fremont, Santa Rosa, and unspecified portions of Napa County, Sonoma, Alameda County, and Marin County. This breadth means if you live in one of these places, you can walk in with confidence that Adore understands your city's ADU rules and design guidelines. If you live outside the pre-approved list, the firm can still take on custom design-build work, but you will go through a longer design review cycle. The large approved area speaks to either a very busy firm that has worked in dozens of jurisdictions or a strategic focus on building relationships with major planning departments.
For a Bay Area homeowner considering an ADU, Adore Homes represents a rare combination: deep local reach, transparent pricing at multiple price points, and genuine choice between prefab speed and site-built flexibility. The firm's willingness to publish detailed model names, square footages, and starting prices is unusual in an industry where most competitors deflect pricing to phone calls. The structured nine-step process and documented timeline reduce ambiguity about what you are signing up for. The dual construction capability means the firm is not pushing prefab units on hillside properties that need site-built flexibility, nor refusing complex projects because they do not fit a manufacturing template. If you value clarity, choice, and a firm that has done this work repeatedly across the Bay Area, Adore Homes deserves a close look.
