About Hafez Zabihollahi

Decades of building houses, not just inspecting them.

Hafez Zabihollahi has spent decades in civil engineering and hands-on residential construction โ€” foundations, structural framing, and the everyday judgment calls made on a job site.

That background is the difference between reading a checklist and understanding how a house was actually put together: what a builder would worry about, what's simply cosmetic, and what's worth a closer look before you commit.

Hafez holds a Master of Science focused on building foundations and brings decades of civil-engineering and residential construction experience. He is not a California-licensed Professional Engineer.

Why a builder's perspective

A different perspective on the property.

Traditional inspections play an important role in the buying process. A Builder Walkthrough adds another perspective: decades of experience understanding how homes are constructed, how problems develop, and which observations deserve a closer look.

This matters

Findings that could affect safety, structure, or real money get flagged clearly โ€” and explained in plain terms.

This probably doesn't

Cosmetic issues that look scary but aren't get named as such, so they don't distract you from the things that deserve more attention.

Let's investigate this

Anything outside the scope of a walkthrough โ€” or that needs a specialist's tools โ€” gets an honest referral, not a guess.

We also provide independent property assessments for homeowners โ€” cracks, leaks, drainage, or contractor work you want a second opinion on. Contact us to discuss your situation.

How it works

Simple, on your timeline

1

Reach out

Call, text, or email the property address and your timeline โ€” ideally before your inspection contingency deadline.

2

Walk the property

Meet on-site for about 90 minutes. Ask questions in real time as observations come up.

3

Get a photo summary

Receive a concise, plain-language summary with photos shortly after the visit.

4

Decide with confidence

Use the summary to guide your offer, your negotiation, or your next call to a specialist.

Sample findings

Clear findings. Clear priorities.

Every finding gets a photo, a plain-language explanation of why it matters, a severity rating, and a next step.

Reinforcing steel and foundation forms at a residential construction site
Address or investigate

Foundation reinforcement, before pour

Rebar placement and spacing at this stage determine how the foundation performs for decades. Gaps, wrong spacing, or missing ties here are far cheaper to fix now than after the pour.

Recommended next step: verify spacing and ties against the structural drawings before concrete is placed.

Structural steel framing on a building under construction
Appears satisfactory

Structural steel framing

Connections are properly seated and braced, with no visible distortion or improvised fixes โ€” the kind of detail that's easy to miss without construction experience.

Recommended next step: none โ€” continue standard progress monitoring.

The two examples above use real construction photos to illustrate report format. Findings from an actual Builder Walkthrough will reflect the specific property visited.

For real-estate agents

Are you a real-estate agent?

Give your buyers another experienced set of eyes on the property. Builder Walkthroughs are designed to complement the existing inspection and disclosure process โ€” not replace it.

Fast scheduling

Designed around contingency timelines โ€” call or text and we'll find a time that works.

Buyer education

Hafez walks the property with your client and explains observations in plain English.

Independent perspective

No repair work to sell and no contractor upsell โ€” just a builder's read on the property.
