Three brothers, twenty years, one license.

GW Construction Management, Inc. Est. 2006, San Diego.

GW Construction was born from our father's dream: to build spaces that endure and inspire. After his sudden passing, we, his sons, came together to carry that vision forward. Every beam we set and every nail we drive is a tribute to his life and his work. We don't just build structures; we build legacies, including our own.

We specialize in building new single-family homes, as well as additions, kitchen and bath renovations, and tenant improvements. Our mission is simple: exceed client expectations, earn their trust, and inspire the word-of-mouth referrals that have kept us busy since 2006.

Unlike many builders who only bid on completed plans, we partner with our clients every step of the way. From initial concepts and design to engineering, permits, and final construction, we ensure a seamless and stress-free experience from start to finish.

Family-owned and operated, GW Construction brings the accountability of a small team with the capability of a full-service firm.

Our purpose

To honor the legacy built before us by raising the standard of what it means to be a contractor.

Our standards

01
Build it right the first time
No shortcuts. Attention to detail, proper sequencing and proven practices that prioritize durability, safety and long-term performance.
02
Transparent communication
Consistent updates, clear expectations and honest recommendations. Good news or a challenge, you always know where your project stands.
03
Planning before building
Significant time goes into estimating, planning, budgeting, scheduling and coordination to minimize surprises and delays.
04
No corners cut
The parts you can't see — waterproofing, structural integrity, flashing, framing — are what determine how a home performs for years.
05
Ownership & accountability
We treat every project as our own, stand behind our work and hold ourselves to a higher standard than code requires.

Answers from GW

Common questions

Is this a quote?

No. It's a planning range from recent GW projects. GW prices your project after design and a site visit, and in design we work to your budget.

What happens after I book?

Cayden calls to go over your goals, then we set up a site visit. You leave with a clear next step, and a design proposal if the project fits.

Can I stay in my house during construction?

For a detached ADU, usually yes. Additions and remodels depend on the scope; GW plans the sequence with you so you know what to expect.

Do I have to be home during the work?

No. GW manages the site, and you get regular updates.

Who handles design and permits?

Studio 1904, GW's design partner, together with GW: drafting, survey, structural, Title 24 and permit facilitation. One team, one point of contact.

How long does it take?

Design is about 2 months with quick decisions. Permits usually run 5–8 months (small ADUs can be faster). Construction is 5–8 months for most ADUs.

Can I rent out an ADU?

Yes, in the City of San Diego. Short-term rentals are not allowed: stays must be 30 days or longer. The chat can walk through your options.

What's not in the price?

See the "Not in this price" list on your snapshot: solar, SDG&E meter work (carried as an allowance), City main upgrades, gas, City fees and design are priced separately.

How do I pay? Can I finance it? Ask Cayden

GW uses a milestone payment schedule written into the contract. Homeowners typically use a HELOC, a cash-out refinance or a renovation loan; GW can point you to lenders it has worked with.

Preliminary feasibility only. Not a quote, an approved plan or a code determination.
