Townhome Inspection Cost: What Are You Actually Paying to Have Inspected? (2026)

A townhome inspection in San Diego runs somewhere between $400 and $600. That range probably isn't surprising. What tends to catch buyers off guard is how much the cost swings based on factors they didn't think about when they budgeted for it: what the HOA covers versus what they own, the square footage, the building's age, roof access, and whether they add services like a sewer scope or mold testing.

The price tag also tends to confuse buyers who've been quoted $300 for a condo inspection and wonder why a townhome costs more. The answer is scope. A condo inspection evaluates the interior of your unit. A townhome inspection, in most cases, evaluates the interior plus the roof, the foundation, the exterior walls, the attic, the garage, and the site drainage. More components, more time, more detailed report. That's what you're paying for.

This guide breaks down exactly where your inspection dollars go, what drives the price up or down, what add-on services cost separately, and how San Diego's market compares to national averages.

National Averages vs. San Diego Reality

According to HomeGuide's 2026 home inspection cost data, a standard home inspection nationally costs $200 to $500, with the average around $340. California inspections trend toward the higher end of that range ($350 to $500) because of higher labor rates and cost of living.

San Diego sits squarely in coastal California pricing territory. A standard single-family home inspection here runs $400 to $700 depending on size. Townhomes fall at the lower end of that range because they're typically smaller than detached homes, but they cost more than a flat condo inspection because the scope is wider.

Here's how the property types compare in San Diego:

Property Type	Typical San Diego Cost	Approximate Time On-Site	Why the Cost Differs
Condo (flat/high-rise)	$300 to $500	1.5 to 2.5 hours	Interior only, no roof/foundation/exterior
Townhome-style condo (HOA covers roof/exterior)	$350 to $500	2 to 2.5 hours	Interior plus limited exterior checks
Townhome (owner owns roof/exterior)	$400 to $600	2.5 to 3.5 hours	Full scope including roof, foundation, attic, garage
Single-family home	$400 to $700+	2.5 to 4+ hours	Full property including lot, all exterior, all systems

Ranges are general estimates for San Diego County. Actual pricing varies by inspector, property condition, and scope.

What Drives the Cost Up

Square Footage

Most inspectors use square footage as the starting point for pricing. A 1,200-square-foot two-bedroom townhome takes less time than a 2,400-square-foot four-bedroom with a two-car garage and three bathrooms. More square footage means more outlets to test, more plumbing fixtures to check, more windows to evaluate, and more time on-site.

HomeGuide reports that national inspection costs by size break down roughly as follows: under 1,000 square feet costs $200 to $250, 1,000 to 1,500 square feet costs $250 to $300, and 1,500 to 2,000 square feet costs $300 to $400. In San Diego, add roughly 20% to 30% to those figures for the local market adjustment.

Ownership Scope

This is the factor unique to townhomes. If your CC&Rs say you own the roof, foundation, and exterior, the inspector evaluates all of those components, and the price reflects the additional work. If the HOA covers the roof and exterior (which happens in some townhome developments), the inspection scope narrows closer to a condo evaluation, and the price drops accordingly.

This is why telling the inspector what the CC&Rs say before booking matters. The scope, the time, and the price all follow from the ownership structure.

Building Age

Older townhomes take longer to inspect because there's more to find. A 2005 townhome in Mira Mesa has systems at or past their expected lifespans (water heater, HVAC, possibly the roof). A 2020 townhome in Otay Ranch has newer systems with fewer wear-related findings. Some inspectors charge $50 to $100 more for homes built before 1990 because of the additional time needed to evaluate aging components and materials.

Roof Type and Access

Tile roofs (extremely common in San Diego townhome developments) require more careful evaluation than composition shingle roofs. Walking on tile risks cracking them, so some inspectors use drone imagery instead of (or in addition to) walking the surface. Drone access may add $75 to $200 to the inspection cost, but it provides detailed imagery without damaging fragile tiles.

Steep roofs and multi-level configurations also add time and complexity. A three-story townhome with roof planes on multiple levels takes longer to evaluate than a two-story with a single accessible roof plane.

What's Included in the Base Price

A standard townhome inspection in the $400 to $600 range covers evaluation of all major systems your ownership includes. Here's the breakdown:

Interior systems (covered in every townhome inspection regardless of ownership scope): electrical panel and all accessible wiring, outlets, and switches. Plumbing supply lines, fixtures, drains, and water heater. HVAC system (heating, cooling, ductwork, thermostat response, condensate drainage). Kitchen appliances (dishwasher, disposal, range, range hood). Bathroom fixtures and ventilation. Windows and doors (operation, seals, hardware). Ceilings, walls, and floors (moisture, cracking, condition). Laundry connections and dryer venting.

Exterior and structural (covered when you own these components): roof surface, flashing, drainage, and penetrations. Foundation (visible portions, cracking patterns, moisture). Exterior walls (stucco, siding, sealant, paint condition). Attic (insulation, ventilation, moisture, framing). Garage (door, opener, fire separation, electrical). Site drainage and grading around the foundation. Balcony or patio (surface, drainage, railing).

The report: Every finding documented with photos, organized by system, with descriptions in plain language. Defects, safety concerns, and maintenance items identified. Recommendations for further evaluation where applicable.

What's Not Included (Add-On Services and Their Costs)

The base inspection covers the accessible, visible components. Several systems require specialized evaluation that's priced separately.

Add-On Service	Typical Cost (San Diego)	What It Covers	When to Get It
Sewer scope	$200 to $500	Camera inspection of the sewer lateral from cleanout to city main	Townhomes with individual laterals (not shared building stacks)
Mold testing	$300 to $600	Air and surface sampling for mold presence and type	When moisture conditions or musty odors suggest mold
Termite/pest inspection	$75 to $200	Wood-destroying organism inspection (WDO)	Standard in most San Diego transactions
Thermal imaging	$150 to $300	Infrared scan for hidden moisture, insulation gaps, electrical hot spots	Older townhomes or when moisture concerns exist
Drone roof inspection	$75 to $200	High-resolution aerial imagery of roof surface	Tile roofs, steep slopes, or inaccessible roof areas

The sewer scope deserves specific mention for townhomes. Unlike condos in high-rise buildings (where the sewer lateral belongs to the association), townhomes often have their own individual sewer lateral connecting to the city main. That lateral is your responsibility, and its condition is invisible without a camera. Our sewer scope inspection guide covers what the camera reveals and why it matters.

Cost vs. Value: The Comparison That Matters

The inspection costs $400 to $600. Here's what the findings can save you.

Common Finding	Typical Repair/Replacement Cost	Would Inspection Catch It?
Roof replacement approaching	$5,000 to $15,000	Yes (condition assessment, age evaluation)
HVAC at end of life	$4,000 to $8,000	Yes (age, performance testing)
Water heater past lifespan	$800 to $2,000	Yes (age, condition, safety device check)
Stucco moisture intrusion	$2,000 to $10,000+	Yes (exterior evaluation, moisture meters)
Grading directing water toward foundation	$1,500 to $5,000 to correct	Yes (site drainage evaluation)
Sewer lateral root intrusion	$3,000 to $15,000	Yes (with sewer scope add-on)
Electrical panel safety concern	$1,500 to $3,000	Yes (panel evaluation)

A single finding from that list pays for the inspection multiple times over. And documented findings give you negotiation leverage: you can request a price reduction, seller repairs, or credits that directly offset the inspection cost.

Tips for Getting the Best Value

Bundle services when possible. Most inspection companies offer package pricing when you combine the base inspection with a sewer scope, mold testing, or thermal imaging. The bundled price is typically 10% to 15% less than booking each service separately.

Know your ownership scope before booking. If your CC&Rs say the HOA covers the roof and exterior, tell the inspector upfront. You'll get a properly scoped inspection at the right price instead of paying for components that aren't your responsibility.

Don't shop on price alone. The cheapest inspection may use less experienced inspectors, spend less time on-site, or produce a thinner report. Ask what's included, how long they spend on-site, what certifications they hold (ASHI, InterNACHI), and whether the report includes photos.

Attend the inspection if you can. Walking the property with the inspector gives you context that the written report alone doesn't convey. You'll see the findings firsthand, ask questions in real time, and understand the relative severity of different items.

How We Price Townhome Inspections at 360

We don't quote a flat rate without knowing what we're inspecting. The ownership scope, the unit size, the building age, and the roof type all factor into pricing. A buyer who owns the roof and exterior gets a different scope (and a different price) than one whose HOA handles those components.

What stays consistent: we spend the time the property actually needs. We don't rush through a 2,400-square-foot townhome in 90 minutes to hit a schedule. Every system gets evaluated, every finding gets documented with photos, and the report reads like information you can act on, not boilerplate you have to decode.

For townhome buyers who also need a sewer scope, we offer that as a combined service. We also offer mold testing when moisture findings during the inspection suggest it's warranted.

Our townhome vs. condo inspection comparison explains how the property type shapes the scope, and our home inspection buyer's guide covers the full evaluation for buyers at any property type.

Frequently Asked Questions About Townhome Inspection Costs

Q: How much does a townhome inspection cost in San Diego?

Most townhome inspections in San Diego cost $400 to $600 for the base inspection. The price varies based on square footage, building age, roof type, and whether the ownership scope includes the roof, foundation, and exterior. Add-on services like sewer scope ($200 to $500) and mold testing ($300 to $600) are priced separately.

Q: Why does a townhome inspection cost more than a condo inspection?

Scope. A condo inspection evaluates the unit interior because the building belongs to the HOA. A townhome inspection typically adds the roof, foundation, exterior walls, attic, garage, and site drainage because you own those components. More systems evaluated means more time and a higher price.

Q: What's included in the base townhome inspection price?

The base price covers evaluation of the electrical system, plumbing, HVAC, water heater, kitchen appliances, bathrooms, windows, doors, ceilings, walls, floors, and (when you own them) the roof, foundation, exterior, attic, garage, and site drainage. The report with photos is included.

Q: Should I add a sewer scope to my townhome inspection?

If your townhome has its own sewer lateral (common in most townhome developments), yes. The sewer lateral is underground and invisible without a camera. A scope costs $200 to $500 and can identify root intrusion, corrosion, and structural problems that would cost $3,000 to $15,000 or more to repair.

Q: Does the inspection cost change if my HOA covers the roof?

It should. If the HOA maintains the roof and exterior, the inspector doesn't need to evaluate those components, which reduces the scope and the price. Make sure to communicate your HOA's coverage to the inspector when booking so the inspection is priced correctly.

Q: How long does a townhome inspection take?

Typically 2.5 to 3.5 hours on-site for a full-scope townhome inspection. Smaller units or townhome-style condos with narrower scope take 2 to 2.5 hours. Adding a sewer scope adds 30 to 45 minutes.

Q: Is a townhome inspection worth the cost?

The inspection costs $400 to $600. A single roof replacement runs $5,000 to $15,000. An HVAC replacement runs $4,000 to $8,000. A sewer repair runs $3,000 to $15,000. One finding from the inspection that leads to a seller credit or price negotiation covers the cost multiple times over.

Q: Can I negotiate the inspection price?

Bundling services (inspection plus sewer scope, or inspection plus mold testing) typically saves 10% to 15% compared to booking separately. Beyond that, inspection pricing is fairly standard within a market. Focus on value (scope, time, report quality, certifications) rather than the lowest price.

Q: Do I need a separate termite inspection for a townhome?

In most San Diego real estate transactions, a termite (WDO) inspection is standard and often ordered by the seller or the seller's agent as part of the transaction. If one isn't being provided, adding it costs $75 to $200 and is worthwhile in San Diego where subterranean termites are active year-round.

Q: What certifications should my townhome inspector have?

Look for inspectors certified by ASHI (American Society of Home Inspectors) or InterNACHI (International Association of Certified Home Inspectors). These certifications require training, testing, and adherence to standards of practice. Experience with attached homes and familiarity with San Diego's building stock (stucco construction, tile roofs, coastal conditions) are also important.

Where Your Money Goes

A townhome inspection isn't a commodity where cheaper is better and more expensive is a rip-off. It's a service where the price reflects the scope, the time, the expertise, and the quality of the documentation you get at the end.

$400 to $600 for a thorough evaluation of every accessible system in a property you're about to spend $500,000 to $900,000 on is not an expense. It's information. And in a real estate transaction, information is the only thing that protects your money.

Cost estimates in this article reflect general ranges for the San Diego County market as of 2026 and will vary by property size, age, inspection scope, and inspector qualifications. Always confirm pricing and scope before booking.
