Edri Construction
Tap a star to rate
Edri Construction operates as a full-service design-build firm serving San Francisco and Marin County, two of the Bay Area's most architecturally demanding territories. Based in the Mission District at 701 Cortland Avenue in San Francisco, the company brings together design expertise and construction capability under one roof, a model that eliminates the coordination gaps that plague projects split between separate architects and builders. With 241 verified photos and 77 reviews on Yelp, the firm has built a substantial portfolio of residential work including ADUs, complete home remodels, and garage-to-office conversions. This scale of documented work is a marker of both output volume and client satisfaction; each photo typically represents a client decision to document their completed project publicly.
What distinguishes Edri is the tighter integration of design thinking into construction. In San Francisco and Marin, where lot constraints are severe and building codes stringent, the ability to design a project with an eye toward constructability before any permits are filed makes a material difference. The firm's approach begins with a thorough site assessment, understanding the property's challenges (foundation conditions, setbacks, topography, tree preservation, utility access), and designing the ADU to work within those constraints rather than against them. That up-front design work catches problems early when they're cheap to solve, not mid-construction when a change order arrives. This is especially critical in San Francisco, where most lots are urban infill with existing structures, narrow street access, and zero room for error. Similarly, in Marin, where many properties are on hillsides with significant soils and drainage issues, the design-build approach means structural and soils engineers are engaged during design, not scrambled in later.
Edri's service range covers the full arc of a residential ADU project. The design phase produces detailed drawings, 3D renderings, and material specifications tailored to the site and the client's intentions. The permitting phase navigates the San Francisco or Marin Building and Planning Departments, a process that demands familiarity with local zoning quirks and precedent. In San Francisco, this means understanding the city's ADU-specific regulations, height planes, rear-yard requirements, and off-street parking exemptions. In Marin, it often involves navigating county-level rules while respecting municipal variations across the county's diverse jurisdictions. The construction phase handles all trades: framing, electrical, plumbing, HVAC, interior finishing, and final inspections. The firm also carries workers' compensation and liability insurance, a baseline for any legitimate Bay Area builder but one worth confirming given the number of uninsured or underinsured operations in the region. This coverage matters particularly on urban infill projects where a site accident poses liability to neighbors and the municipality.
A typical ADU build in San Francisco or Marin takes three to six months of construction time, though permitting often adds another two to four months before any ground is broken. The total project arc from initial consultation to Certificate of Occupancy frequently spans six to twelve months, depending on the complexity of the site and the responsiveness of the local jurisdiction. Edri's portfolio of 241 Yelp photos across San Francisco and Marin projects reflects sustained volume through both Planning Departments, giving the firm repeated experience with the specific code chapters, design preferences, and permitting timelines each jurisdiction demands.
The firm's portfolio reveals work across a range of property types and sizes. Some projects are new detached ADUs built on vacant portions of a lot, others are conversions of existing structures (a garage converted to an income-producing unit, a side-lot coach house built above a hillside yard). This range of project types, new-construction detached units, existing-structure conversions, sloped sites, and tight urban infill, reflects work adapted to different site conditions and owner needs. Bay Area ADU sites are rarely alike, and Edri's experience span reflects that reality. For homeowners in Marin, where many properties sit on hillsides with significant soils and access challenges, the ability to work with structural engineers and address drainage and retaining wall conditions during design is a practical advantage. The firm's structural expertise means they can design an ADU foundation that works on a slope, not one that tries to force a flat template onto uneven ground. For San Francisco homeowners, the firm's familiarity with the city's specific code chapters and the Planning Department's stance on parking, setbacks, and materials is valuable shorthand that accelerates permitting. They know which Planning Departments are receptive to certain design moves and which require more justification, allowing them to propose designs likely to sail through review rather than bounce back and forth.
Pricing for ADU work in the Bay Area typically ranges from $200,000 to $400,000 depending on size, finishes, and site conditions, though Edri, like most design-build firms, quotes on a project-by-project basis. The firm's design-build model means the price is fixed once the design is approved and the scope locked, eliminating the separate fee for an architect and the variable costs of working with an architect and builder who aren't coordinating closely. For homeowners, this can mean lower total project cost than the traditional separate-contracts approach, particularly on smaller sites where coordination losses are most acute.
The company's reach in the market is Marin and San Francisco only. For residents of the outer East Bay, South Bay, or Peninsula, Edri is not an option. The geographic focus makes sense for a firm built on design-build integration: serving both a narrow territory and a full spectrum of project types (ADUs, remodels, conversions) requires deep knowledge of local codes and relationships, and it's hard to maintain that depth across more than a few neighboring jurisdictions. This focus is a strength for homeowners in their service area but a practical barrier for anyone outside it.
Edri Construction suits homeowners who value integrated design and construction, especially those on challenging sites. It's a good fit for someone who wants a single point of contact from initial design through final walk-through, and who prefers the predictability of a fixed-price design-build contract over the variable costs of hiring an architect and contractor separately. The firm's portfolio and review count suggest proven execution; the main limiting factor is geographic reach.
