About Us
What We Do: The Integrated Authority in Design, Advisory, and Construction
JMJ Custom Builds is built on over 25 years of design and construction execution, redefined by a commitment to strategic counsel and regulatory mastery. While we remain dedicated to superior custom construction, our expertise extends far beyond the job site. We are the trusted source for attorneys, developers, property managers, and sophisticated buyers who require unbiased technical due diligence, advanced land use strategy, and definitive dispute resolution. We don't just build projects; we provide the forensic knowledge and strategic oversight necessary to mitigate risk, maximize land value, and navigate complex regulations with absolute certainty.
At JMJ Custom Builds, we have redefined the role of the construction firm. We are not simply General Contractors in San Diego County; we are an integrated technical authority led by a unique partnership mix of licensed General Contractor with deep trade expertise, a Civil Engineering design specialist and an approach to entitlement that focuses on a Max Land Use Investment Strategy.
This unique structure allows us to eliminate the common friction points between planning, permitting, and execution, giving our clients a single, reliable point of contact for complex San Diego construction and regulatory challenges.
We provide service across four essential pillars:
Land Development
Planning Design and permitting
Construction
Advisory Services
1. Regulatory Strategy & Design
This pillar leverages our in-house expertise to ensure your Alpine, CA project is viable, permitted, and optimized for success before ground is ever broken. We solve regulatory and land entitlement problems that stop most developers and homeowners.
- Raw Land Strategy: Advanced counsel on raw land entitlement, zoning compliance, Lot Splits (SB9/SB10), and development feasibility to maximize San Diego land value.
- Permitting & Compliance: Comprehensive in-house drafting, design, and full permit processing in San Diego. We specialize in resolving active Code Case Violations and securing 'As-Built' permits to bring non-compliant structures into legal standing throughout the county.
- Site Technical Coordination: Expert management of pre-design necessities, including boundary surveys, easements, site measurements, and access to crucial San Diego County development records.
2. Technical Oversight & Due Diligence
We act as an unbiased, technical resource for investors, legal counsel, and property owners across San Diego, providing forensic analysis and counsel to mitigate financial and legal risks in real estate.
- Construction & Legal Counsel: Providing definitive answers for complex situations, including Construction Expert Witness and Testimony for San Diego Attorneys, and specialized Mediation for construction disputes.
- Quality Assurance: Unbiased 3rd Party Review of contractor estimates, scope, and contracts to protect customers. This includes multi-phase Quality of Work Inspections to ensure field execution meets code and best standards.
- Home Buyer Due Diligence: Replacing redundant home inspections with a comprehensive, contractor-grade home inspection that includes a professional, costed estimate for repairs, providing true financial clarity for buyers in the San Diego real estate market.
3. Custom Construction & Execution
This is where our expertise translates into physical reality. Our licensed General Contractor ensures that the highest standard of quality and project management rigor is applied to every build, from Alpine to the coast.
- Precision Execution: Specializing in New Custom Homes in San Diego County and Major Remodels, we apply seasoned trade expertise and critical path methodology to prevent field conflicts, eliminate delays, and guarantee schedule certainty.
- Alternative Structures: We are the regulatory bridge for unique projects, specializing in permitted and engineered Natural Building Construction methods, including Cob, Haybale, Earthbag, Air-Crete Domes, Barn-dominiums, and Permanent Foundation Tiny Homes in San Diego.
- Portfolio Services: We offer specialized support for professional property managers through our 'Fleet Services' (embedded construction management) and serve as a reliable Preferred Vendor for all contract repairs, tenant improvements, and capital additions.
Working Together
We understand honesty as a virtue that requires fearless communication throughout the entire building process. Providing realistic expectations, early and often, is how we best achieve our core values: Honesty, Accuracy & Commitment!
