Advance Construction Company

Advance Construction Company, operating under CSLB License #1018840, was founded in 2016 by Anthony Gonzales, a lifetime San Diego native whose construction background runs deep into his family. Before launching Advance, Gonzales spent ten years working across every level of his family's construction operation, from laborer roles to management positions. That progression through the trades, where he built competence in how things are actually made and not just how they are sold, shapes how Advance approaches projects. The founding of Advance in 2016 marked a decision to specialize. Rather than remaining a general contractor, Gonzales positioned the firm as an ADU-focused builder at a moment when San Diego's housing conversation was beginning to turn toward accessory units as a practical answer to rental housing scarcity.

The company positions ADUs as a smart investment, a frame that recognizes both the utility of the unit and its economic case. An ADU produces rental income, adds property value, and provides flexibility for multi-generational living or guest housing, depending on the owner's needs. Advance positions itself as the firm that handles the full scope of that investment, from concept through construction to keys in hand. The turnkey framing matters because it acknowledges that many property owners in San Diego are not builders and are going through the ADU process for the first time. A prospective client does not need to hire an architect separately, negotiate permits on their own, or coordinate design and construction across multiple vendors. Advance coordinates design partnerships and permitting, pulling together the pieces of the project under one contract.

The firm's service area covers all of San Diego County, from Oceanside in the north through coastal communities, inland North County, the city proper, East County, and South County down to Chula Vista and National City. That county-wide reach is a logistical decision most smaller builders would not attempt. Regional specialization is common; county-wide coverage requires operations, project management, and crew coordination at a different scale. Advance's commitment to serving every subregion of the county suggests a business that has grown past the single-location model. Clients in National City looking for an ADU builder do not have many options; Advance is among them. Clients in Oceanside have more choice, but Advance being available across that geography reduces the search friction.

Advance Construction maintains a 5-star rating on Google with 15 verified customer reviews. In the construction industry, a 5-star average across a meaningful sample suggests consistent performance and reliable client communication. Reviews in this category tend to cluster around on-time delivery, staying on budget, quality of work, and responsiveness to questions. A firm with 15 verified reviews spanning a broad geographic service area is not a new startup; it is a company with enough completed projects that a representative sample can accumulate. The firm also holds BBB accreditation, which requires adherence to ethical standards and responsiveness to complaints through a formal dispute process. BBB membership is not a mark of superiority over non-members, but it is a voluntary commitment to a third-party standard and a grievance mechanism. Many San Diego contractors do not bother. Advance's decision to accredit signals accountability.

The operational structure reflects growth in the decade since 2016. A founder who started as a laborer in his family's business and then founded Advance ten years later is now running a company serving an entire county with multiple concurrent projects. That trajectory suggests a builder who understands the work intimately but has also built management competence across hiring, training, scheduling, and quality control across multiple teams. The "10+ years as Advance" claim in the company's marketing is a minor signal, a way of saying the firm has been building ADUs through multiple market cycles, regulatory changes (including San Diego's ADU bonus program and its rollback), and economic conditions.

Advance's service menu extends beyond ADUs to room additions, full home renovations, kitchen remodels, bathroom remodels, and commercial buildouts. Many successful regional builders diversify their revenue across related services rather than betting everything on a single market niche. A firm that can handle kitchen remodels is likely to have the expertise for plumbing and electrical systems. A firm capable of room additions can manage new structural framing and code compliance. This diversification means that during phases of the market when ADU demand softens, Advance is not stranded. It also means that a client who wants an ADU but has a separate kitchen remodel need can potentially hire Advance for both projects and benefit from streamlined coordination. The firm's licensing and operational capacity for multiple service lines reflects a degree of sophistication and financial stability.

Pricing for ADU projects is not listed on Advance's site as a fixed menu. This is standard across high-touch builders who price projects individually based on lot conditions, client specifications, local permitting, and market costs at the time of bidding. What Advance does communicate is flexibility around financing. The company offers multiple financing arrangements, suggesting partnerships with lenders or in-house financing knowledge that can help clients structure a project that works within their cash-on-hand situation. For a substantial project like an ADU, financing terms can determine feasibility for some property owners. A builder who can speak competently to financing options reduces a major barrier to moving forward.

San Diego's ADU regulatory environment is the operational context for every builder in the category. The city's prior bonus program, which offered density relief and parking exemptions, was a substantial incentive. The June 2025 rollback of that program re-imposed restrictions and reduced eligibility. Advance, operating since 2016, has built ADUs under the generous regime and now builds under the tighter one. Long-standing builders understand the permitting landscape, have relationships with the city agencies, and can work within the current constraints. A client wondering whether their property qualifies for an ADU or what the new restrictions mean should expect Advance, as a county-wide builder, to have informed perspective on this.

Advance Construction Company targets clients in San Diego County who have decided they want an ADU, have a property suitable for one, and want a single contractor who can handle design coordination, permitting, and construction without hiring separate firms. The firm's emphasis on turnkey service and the "smartest investment" framing positions it well for property owners approaching an ADU for the first time and seeking a straightforward path from decision to completion. The 5-star Google rating, BBB accreditation, and ten years of focused ADU experience provide tangible evidence of reliability. Clients in East County, South County, or northern San Diego County, where local option density can be lower, benefit particularly from a builder who truly serves their area rather than treating outlying parts of the county as occasional projects.
