If you’re preparing to sell your home in Marin, one of the most common questions I hear from sellers is:

“What inspections should I actually get before putting my house on the market?”

The answer isn’t the same for every property. But after years of working with Marin buyers and sellers, I’ve found there are a handful of inspections that consistently make the selling process smoother, faster, and less stressful.

More importantly, they help prevent surprises that can derail negotiations later.

Here’s how I typically approach inspections with my sellers…

The Core Inspections I Recommend for Most Marin Home Sellers

For the majority of homes, I recommend starting with four key inspections:

1. General Home Inspection
2. Pest Inspection
3. Sewer Lateral Inspection
4. Roof Inspection

These inspections cast a wide net and help uncover potential big-ticket items before buyers do.

When sellers know the condition of the property upfront, they can decide whether to repair issues or simply disclose them clearly. Either way, it puts you in a stronger negotiating position.

Marin buyers also expect to see a general home and pest inspection in the disclosure package, so providing them upfront can build trust and streamline the process.

Inspections That Depend on the Property

Some inspections only make sense depending on the specific features of your home.

For example, I may recommend:

• Chimney inspection if the fireplace is a major feature or primary heat source
• Pool inspection if the property has a pool
• Septic and well inspections for homes outside municipal systems

For properties on septic or well systems, those inspections are essentially non-negotiable, since buyers and will always want to understand the condition of those systems.

Inspections I Rarely Recommend Upfront

There are also inspections that I usually leave for the buyer, because they tend to be highly specific to individual concerns.

These include:

• Mold testing
• Geotechnical or soil testing
• Property surveys

These types of inspections often depend on the buyer’s personal risk tolerance or future plans for the property.

Marin-Specific Requirements Home Sellers Should Know

One thing that makes Marin County different from other markets is that some cities and districts require specific point of sale inspections.

For example, several Marin communities require a resale inspection before a property can transfer ownership, including:

• Fairfax
• Tiburon
• Corte Madera
• Mill Valley
• San Anselmo (although this is currently under review)

Additionally, many Marin homes located in High or Very High Fire Hazard Severity Zones must complete a defensible space or fire safety inspection before closing.

Sewer lateral compliance is also important in many areas. Districts such as:

• Las Gallinas Valley Sanitary District
• Ross Valley Sanitary District
• Sausalito-Marin City Sanitary District
• Sanitary District No. 5 (Tiburon)
• City of Mill Valley

often require sewer lateral compliance as part of a sale.

Because each district has different rules and timelines, this is something I always verify early in the listing process.

The Expensive Problems Home Inspections Often Uncover

Most inspection reports will reveal at least a few issues. That’s normal. But there are a few items that tend to be the most expensive when they show up.

Some of the most common include:

Electrical Panels

Older Zinsco or Federal Pacific panels frequently appear in Marin homes. Many insurance companies require these to be replaced, which makes them a common negotiation point. Even if you aren’t selling your home yet insurance companies are still inspecting your home.

Sewer Laterals

Replacing a sewer lateral often starts around $12,000, but can be significantly higher depending on length or access.

Large Deck Repairs

Oversized decks are common in Marin hillside homes. When pest inspections identify extensive wood damage, repairs can sometimes run $20,000–$50,000 depending on the scope.

The Issues That Scare Home Buyers the Most

Not every issue carries the same emotional weight with buyers.

The two things that tend to cause the biggest concern are:

• Foundation issues
• Hillside stability

Buyers sometimes worry these could lead to catastrophic structural problems or six-figure repairs, even when the reality is more manageable.

This is why clear inspections and expert guidance can be so valuable in helping buyers understand what is actually typical for Marin homes.

Why Doing Inspections on Your Home Upfront Can Strengthen Your Sale

Providing inspections before listing often leads to faster transactions and fewer surprises.

When buyers know the condition of the property upfront, it helps set clear expectations.

For example, if the roof inspection states that the roof has 3–5 years of useful life remaining, buyers typically factor that into their offer instead of requesting a surprise credit later.

Upfront inspections can also encourage buyers to keep their investigation period shorter, which helps the transaction move more smoothly.

A Real Example: When Skipping a Home Inspection Cost the Seller $$

I once represented a buyer on a property where the seller had not completed a sewer lateral inspection ahead of time.

We were transparent that my client would conduct that inspection during the investigation period.

The result?
The sewer lateral needed to be replaced. and it was a long one. Over 300′ because it had to connect to the sewer main at the bottom of the hill.

The estimate came in at $30,000.

My buyer negotiated a credit for roughly half of that amount. The listing agent was frustrated, but the reality was simple:

If the seller had spent a few hundred dollars on the inspection beforehand, they could have controlled the narrative and pricing strategy much earlier.

Should You Fix Problems the Inspections Uncover Before Selling?

Not always.

My strategy with sellers is usually guided by three questions:

1. What repairs offer the best return on investment?
2. What issues will buyers focus on the most?
3. What could create obstacles with buyers, insurance, or lenders?

One thing I almost always recommend addressing is active leaks. Water issues can escalate quickly and buyers almost always ask about them.

Beyond that, the goal isn’t to deliver a perfectly renovated home.

Instead, it’s about presenting a property that feels well cared for and transparent, while disclosing both the repairs that were completed and any remaining issues.

In Marin’s market, buyers are paying significant prices, and homes that feel “turn-key” (or close to it) tend to attract stronger offers.

The Bottom Line

Pre-listing inspections are ultimately about reducing uncertainty.

They help sellers:

• Set clear expectations with buyers
• Avoid surprise negotiations
• Strengthen offers in competitive situations
• Move through escrow with fewer delays

And in a market like Marin, where transactions involve significant investments, that clarity can make a meaningful difference.
