House Flip Electrical and Rental Property Electrical Inspections in San Antonio

Key takeaways

  • House flip electrical work is judged twice: by the city inspector if it was permitted, and by the buyer's inspector at resale.
  • Budget the electrical scope after a licensed electrician's evaluation, not before, because panel brand, wiring type and service size can change the number substantially.
  • Unpermitted electrical work on a flip tends to surface during the buyer's option period, when it costs you the most.
  • Rentals need working smoke alarms, carbon monoxide alarms where there is a fuel-burning appliance or attached garage, and GFCI protection in wet areas before each new tenant.
  • One licensed electrical vendor across a portfolio gives you consistent pricing, consistent reports, and one standard for every unit.

If you flip houses or hold rentals in San Antonio, electrical is the line item that most often surprises you after you have committed. House flip electrical work is judged at resale by the buyer's inspector, and a rental property electrical inspection decides whether a unit is ready for the next tenant or ready for a problem. Both come down to the same thing: knowing what is in the walls before you set the budget, and fixing it to a standard that holds up when someone else looks.

This guide is written for investors and landlords. It covers what a buyer's inspector will flag on resale, how to budget, how permits work on a flip, what tenants need from the electrical system, and why an evaluation between tenants pays for itself.

House flip electrical: what passes the buyer's inspection on resale

Your buyer will hire a home inspector who fills out the TREC inspection report. That inspector is not checking whether the house looks finished. They open the panel, test outlets, look in the attic, and compare what they find to current safety standards. Fresh paint and new fixtures do not hide a panel full of double taps or a bathroom without GFCI protection. Every item they write up becomes a repair request or a price reduction during the buyer's option period.

The items that most often appear on flips we see:

  • Federal Pacific or Zinsco panels left in place because the house had power and the lights worked.
  • Double-tapped breakers and missing or mislabeled circuit directories.
  • Three-prong outlets installed on ungrounded circuits, which test as open ground.
  • Missing GFCI protection in kitchens, bathrooms, the garage, the laundry and outdoors.
  • New light fixtures hung on old boxes without proper support, or with open splices in the attic.
  • Smoke alarms missing from bedrooms or not interconnected where the rest of the work triggered that requirement.
  • Exterior outlets without in-use covers.
  • Signs of do-it-yourself work, such as extension cord wiring, exposed cable runs, and uncovered junction boxes.

Order matters on a flip. Electrical rough-in belongs before insulation and drywall go up, because a circuit added after the walls are closed costs more and leaves patches to finish. Bring the electrician in at demolition, settle the scope while the walls are open, and schedule the rough-in inspection before the drywall crew arrives. The final inspection follows once devices and fixtures are set. On a tight hold, that sequence is what keeps electrical off the critical path, and a house that closes up on schedule is a house that lists on schedule.

None of these are expensive to correct before listing compared to what they cost in a negotiation. A buyer who sees a Federal Pacific panel on the report will often ask for more than the replacement costs, because they are pricing in uncertainty.

Budgeting the electrical on a flip

Most investors set a renovation budget from photos and a walk-through. Electrical is the line where that approach breaks down, because the expensive items are not visible. The panel brand, the wiring type, the service size, and whether earlier owners added circuits correctly all change the number. A house that looks like it needs new devices and fixtures may also need a panel and a grounding upgrade.

Get a licensed electrician's evaluation during your own option period, or before you close if you are buying another way. Ask for the findings split into three groups: safety items that must be corrected, items a buyer's inspector will write up, and optional upgrades that help the listing, such as more kitchen circuits or exterior lighting. Price each with a flat number. That turns electrical from a guess into a line in your deal analysis.

Two common scope items on flips are a panel change and a device refresh. A like-for-like panel replacement is the right answer for an outdated or flagged panel where the service size is already adequate.

In our book that is the Panel replacement, like-for-like 200A task, from $3,639, with the permit, the city inspection and CPS Energy coordination included. You approve the price before work starts and can put it straight into your budget. Starting price. Your tech confirms the final number on site before any work.

A device refresh replaces worn, painted-over, mismatched or yellowed outlets and switches throughout the house, and it adds tamper-resistant receptacles where they are required. It changes how the house reads in showings and removes a whole category of inspection items at once.

We price it as a single line. Our book lists the Whole-home device refresh task, from $849, which covers the devices, the plates, and testing every outlet as it goes in. Starting price. Your tech confirms the final number on site before any work.

See what drives panel pricing in electrical panel upgrade and replacement cost, and check our flat-rate pricing for how the book works.

Leave a contingency in the electrical line for what turns up once walls are open. Older houses hide splices without boxes, cable damaged by earlier work, and circuits that do not match the panel directory. When we find something like that, we stop, show you photos, and price the added work flat before we continue. You decide, and the budget moves only with your approval.

Permits on flips

In San Antonio, electrical permits are issued by the Development Services Department, and in Texas electrical work must be done by electricians licensed through TDLR. Panel replacements, new circuits, service upgrades and rewiring generally require a permit. Replacing a device with the same kind of device generally does not. If you are not sure, ask before the work starts, not after.

Unpermitted work on a flip is a risk that shows up at the worst time. Buyers' inspectors notice new panels with no inspection sticker. Buyers' agents look up permit history. When a buyer finds a panel swap with no permit during their option period, you are negotiating with a buyer who has just lost trust in the rest of the renovation. A permitted job comes with a city inspection record you can hand them.

We cover what needs a permit and how the process runs in electrical permits in San Antonio. On every job we do, we pull the permit where one is required and meet the inspector, so your project manager does not have to.

Rental property electrical inspection: smoke alarms, CO alarms and GFCI for tenants

A rental carries a different kind of risk. The house is occupied by people who did not choose its wiring and who will not tell you about a warm outlet until it becomes a bigger problem. Texas Property Code places specific smoke alarm duties on residential landlords, including installation and testing at the start of a tenancy. Read the requirements or ask your attorney, and treat them as the floor, not the standard.

The standard we recommend for every unit at every turnover:

  • A working smoke alarm in each bedroom, outside each sleeping area, and on each level, tested at move-in.
  • Carbon monoxide alarms where the unit has a gas furnace, gas water heater, gas range, fireplace or attached garage.
  • Alarms replaced at the end of their service life, which is printed on the alarm.
  • GFCI protection in kitchens, bathrooms, laundry areas, garages and outdoors, with every GFCI tested.
  • No open junction boxes, missing cover plates, or exposed wiring anywhere a tenant can reach.
  • A legible panel directory so a tenant or property manager can shut off the right circuit.

For units that need alarms brought up to date, our book lists the Whole-home detector set task, from $629. It covers the smoke and carbon monoxide alarms the floor plan calls for, installed and tested together, so you can document the unit as ready on move-in day. Starting price. Your tech confirms the final number on site before any work.

See smoke detector placement code for where alarms belong and smoke and CO detectors for how we install them.

A licensed electrician's inspection between tenants

Turnover is the one time the unit is empty and you have access to every room. It is also when tenant damage and tenant modifications come to light: a ceiling fan installed by a previous tenant, a broken outlet behind the couch, a GFCI someone bypassed because it kept tripping. A short evaluation by a licensed electrician at turnover catches those before the next tenant moves in.

What we check at turnover: the panel and breakers, every outlet and GFCI, every smoke and CO alarm, exterior outlets and covers, light fixtures and fans, and anything a tenant added. You get a written report with photos, signed by a Texas licensed master electrician, and a flat price for anything that needs correction. Keep the report in the unit file. If a question ever comes up about the condition of the electrical system at move-in, it is a dated record.

Schedule turnover evaluations through electrical inspections, or call us with the move-out date and we will fit the visit into your make-ready schedule.

One electrical vendor for a portfolio

Investors who own several properties often use whichever electrician is available. The result is different standards on different houses, different prices for the same job, and reports in different formats that are hard to compare. Using one licensed vendor across the portfolio fixes that. The same flat price book applies to every property, the reports read the same way, and the standard at your rental on the east side matches the one at your flip in Live Oak.

We work this way with investors and property managers. We keep a record of each property's panel, service and prior work, so the next call starts from what we already know. Pricing comes from the same published book on every job, and you approve each price before work starts. Wattsmith Electric is veteran-owned and licensed by TDLR under TECL 41806.

If you are the agent representing an investor client, send this page to them before they write the offer, so the electrical number is in the deal analysis and not a surprise in the option period. We cover properties across our service areas, including Live Oak and Converse.

Call us with the addresses in your portfolio and we will set up the first round of evaluations. For repair work as it comes up between turnovers, see electrical repair.
