Replacing a water heater is one of the most common residential plumbing jobs, and one of the most common permit inspections. It is also one of the best candidates for remote inspection. The work is repetitive, the code items are well defined and most of what an inspector needs to confirm can be seen on camera.
That is why water heaters are on California’s must-offer list under AB 1738, which requires cities and counties to offer a remote inspection option for specified residential projects by July 1, 2027. Heat pump water heaters are part of the same trend as states and utilities push electrification. Building departments, contractors and utility programs are all asking the same question: which software should we use?
This guide answers that question honestly. It explains what a water heater inspection needs to capture, which features matter most, how the main categories of software compare and why we recommend Blitzz Inspect for most water heater programs. Because this article appears on Blitzz’s site, treat the comparison as one informed perspective and run your own pilot before you decide.
The scope is narrow. A residential water heater installation has a defined set of components and code checks. An inspector can use a checklist rather than interpret a complex building.
The volume is high. Water heater replacements are frequent, often urgent and typically handled by licensed plumbers who do many installs. Even small savings per inspection add up.
The evidence is visual. Straps, piping, valves, vents, labels and clearances are visible on a phone camera when the person holding it knows where to point.
Timing matters. A homeowner without hot water wants the job closed out quickly. Waiting for an inspector can delay permit sign-off, final payment and the customer’s peace of mind.
It is part of a policy shift. AB 1738 puts water heaters on the list of projects where jurisdictions must offer a remote option. Departments need a workflow before the deadline.
Local codes and checklists vary, so your department’s checklist governs. Permit checklists from several California cities, such as Hayward, Calabasas, Elk Grove and Vacaville, show a similar set of items. These examples are California-specific, so adapt them to your jurisdiction.
| Item | What a reviewer typically needs to see |
|---|---|
| Permit and identification | Permit number, address, data plate with model, serial number, capacity and fuel type |
| Seismic bracing | Straps in the upper and lower thirds of the tank, wrapping around the heater and anchored to the wall, with the lower strap clear of the controls |
| Temperature and pressure relief valve | Valve present, discharge line in approved piping, not trapped, no valve in the line, and terminating at an approved location, often outside the building |
| Combustion air and venting | For gas units, combustion air provision, vent size, slope, connections, clearances to combustibles and the vent termination |
| Gas connection | Shutoff valve, sediment trap and connections for gas units |
| Water connections | Shutoff valve on the cold supply, unions or connectors, and insulation on the first section of piping |
| Expansion tank | Present where the system has a check valve, backflow preventer or other device that prevents pressure from dissipating into the main |
| Drain pan | Required in some locations where a leak could cause damage |
| Electrical | For electric units, a labeled disconnect within sight of the heater |
| Access and working space | Adequate access and clearances, including for attic or closet installations |
| Heat pump water heaters | Data plate, clearances, condensate drainage, electrical connection and any additional manufacturer requirements |
A good platform makes it easy to see these items clearly, record them and attach them to the permit.
Not every video tool is built for inspections. Here are the criteria that matter most for water heater work.
1. App-free access for the person on site. Plumbers, homeowners and subcontractors will not install a new app for one inspection. A browser link that works on any phone removes the biggest barrier. Blitzz’s browser-based video calling uses a unique secure link sent by SMS, email or WhatsApp.
2. Live, guided video with camera controls. The inspector needs to direct the camera. Remote zoom helps read data plates and see strap placement, and remote flashlight control helps in dark closets, garages and attics.
3. Annotation and pointing. Live pointer and markup tools let the inspector show exactly where to look or what to fix, such as “move the camera to the discharge pipe termination.”
4. Photo capture with timestamp and location. HD photo capture and GPS location data tie evidence to the permit and address.
5. Text capture from labels. OCR can extract model and serial numbers from data plates, reducing typing errors.
6. Recording and audit trail. Session recording with consent and logs support disputes, audits and training.
7. Low-signal support. Water heaters are often in garages, basements, closets and attics where signal is poor. Offline mode lets participants capture images and data without a connection and upload later.
8. Permit system integration. Departments need inspections to launch from, and sync back to, the permit record. Blitzz’s Accela integration does this, and other integrations are available.
9. Reporting. An inspection report and AI call summary reduce paperwork and standardize records.
10. Security. Sessions show the inside of homes. Look for encryption, access controls and independent audits. Blitzz describes its approach on its security page.
11. Live and recorded options. AB 1738 lets inspectors use videoconferencing or recorded photos and video, so flexibility matters.
12. Ease of use for non-technical users. The best software works for inspectors with different comfort levels with technology and for homeowners who have never joined a video inspection.
13. Scalability and cost. Programs start small, so look for pricing that fits pilots and grows with volume.
The remote inspection market includes several categories of tools. This table is a general guide based on public vendor comparisons, including comparison pages published by Blitzz and by Fora Soft. Features and pricing change, so verify with each vendor.
| Option | Type | Best for | Strengths | Watch-outs |
|---|---|---|---|---|
| Blitzz Inspect | Live, guided, app-free browser video | Building departments, contractors, insurers and utilities that want one live inspection tool | No-download access, remote zoom and flashlight, annotation, photo capture with GPS, OCR, AI summaries and reports, Accela and other integrations | Some enterprise features may be add-ons, and it is broader than a permit-only tool |
| VuSpex | Virtual inspection built around building departments | Municipal inspection programs that want deep configuration | Built for government building inspections and permit workflows, with a large set of configurable options per Blitzz’s comparison | Described as inspection-focused and less suited to other use cases such as claims |
| Fulcrum | Mobile checklist and field data capture | Teams that want structured forms with photo and video evidence | Checklist-driven capture with timestamps, location and offline capability | Guided live video is more limited than in video-first tools |
| Enterprise AR and remote assist platforms such as SightCall, Librestream and similar | Live video with AR for industrial support | Large organizations with complex equipment support | Strong AR tools and enterprise features | May be more than a water heater program needs |
| Zoho Lens and similar budget tools | General AR remote assist | Small teams on a tight budget | Low per-user cost | Not built for inspection workflows, permit integration or evidence provenance |
| Truepic and similar | Authenticated self-guided capture | Programs that rely on asynchronous photos | Authenticated capture and provenance | Not a live-guided tool |
| General video calls such as Zoom, Teams and FaceTime | General video conferencing | Informal checks | Familiar and low cost | No remote zoom or flashlight control, limited evidence capture, app or account friction |
The right choice depends on who you are. A building department that needs a heavily configured permit workflow might look closely at a municipal-specific platform. A contractor group that wants a simple tool that works across jurisdictions might prefer a lightweight checklist app. A department or contractor that wants live guided inspection with no-download access and strong evidence capture will find Blitzz a strong fit.
For most residential water heater programs, Blitzz Inspect offers the best balance of ease and capability. Here is why.
It works for the person holding the phone. A plumber on site or a homeowner can join from a link and start. That matters when the person is not a technology professional and the inspection has to happen quickly.
It gives the inspector control. The inspector can zoom into the data plate, light up a dark closet, point to the strap and mark the discharge pipe, which is what a water heater inspection needs.
It captures evidence automatically. Timestamped photos, GPS location, OCR text from labels, recordings and reports create a record that supports sign-off and audits.
It connects to permit workflows. The Accela integration launches inspections from permit records and syncs documentation back. Government teams can learn more on the government customers page.
It has a track record with building inspection work. Blitzz’s Aoka Engineering case study describes ICC-certified inspectors conducting virtual inspections for jurisdictions across the U.S., including rural areas where distance and staffing make site visits slow. The case study says real-time annotation and high-quality video help inspectors flag deficiencies and often re-inspect corrections the same day.
It extends beyond water heaters. The same platform can handle solar, HVAC, reroofs and other must-offer projects, and it serves construction and utilities and energy teams too. That means one tool for several programs. For a deeper comparison with a municipal-focused alternative, see Blitzz’s Blitzz vs VuSpex article, and for a broader overview see the guide to the best remote video inspection software.
Here is how a typical live inspection works with Blitzz Inspect.
Some of the most useful evidence is captured before the inspection. BlitzzCam field photo documentation lets plumbers and contractors capture GPS-stamped, time-stamped photos filed by job and phase. For a water heater job, that might mean the old unit before removal, the gas and water connections before they are covered, the strap installation, the discharge pipe routing and the final installed unit with its data plate.
If an inspector asks about something no longer visible, or a homeowner later has a question, the record is already there. BlitzzCam is listed as early access, so confirm availability with the Blitzz team.
Pricing changes, so check each vendor’s current terms. Blitzz publishes Inspect pricing. A third-party comparison from Fora Soft, based on pricing captured in July 2026, estimated that Blitzz’s Professional plan works out to roughly $6.70 per inspection at 600 inspections a year. Treat that as an illustrative estimate and confirm current plans, since some security and integration features may be priced separately.
To judge return on investment, compare the cost per inspection with the cost of a field visit, including inspector time, vehicle expense, scheduling delays and the contractor’s waiting time. For water heaters, which are quick inspections with high volume, avoiding even a portion of site visits can be significant. Programs in other states have reported strong savings. The Interstate Renewable Energy Council estimated that technology-enabled virtual inspections could reduce costs by more than $30,000 per inspector per year, though that figure covers inspections generally rather than water heaters specifically.
Residential water heaters are among the best first uses of remote video inspection. The checklist is clear, the volume is high and the evidence is visual. The best software makes it easy for the person on site to join, gives the inspector control of the camera and leaves behind a trustworthy record.
For most water heater programs, Blitzz Inspect offers that combination, along with the flexibility to expand to solar, HVAC, reroofs and other projects as remote inspection grows under AB 1738 and similar policies elsewhere.
