Searching "demand construction" almost always means one thing: you got a quote, saw an ad, or heard a name and now you want to know if this California solar and roofing company is actually reliable. This review pulls verified license records, BBB data, and documented customer complaints into one place so you're not deciding off a sales pitch alone.
Company Overview: Who Is Demand Construction?
Demand Construction is a solar PV, energy storage, EV charging, and construction company based in San Fernando, California, operating since 2019 . The company has also done business as Demand Solar in other states and shares its San Fernando address with a business called Nation Energy Services, which Yelp lists as established in 2020 and serving California since 2019 under CSLB #1071038, TDLR #37818, and FL EC #13013034 .
That naming overlap matters for anyone trying to research this company. If complaints, licenses, or reviews are split across "Demand Construction," "Demand Solar," and "Nation Energy Services," you need to check all three names before you form an opinion.
Leadership has also been named publicly. A 2024 profile piece reported the executive team includes CEO Jorrel Patterson, President Hosep Bahlounian, CRO Karl Johnstone, CXO Nathan Roberts, and CMO Damla Bahlounian , several with prior experience at other national solar installers. Titles and staff change, so confirm current leadership directly with the company or through state business filings before it factors into your decision.
Is Demand Construction Licensed? BBB Rating & Complaint Volume
This is the part most "demand construction" searches are really after, so here's the direct answer with sources attached.
License status: Third-party license tracker BuildZoom shows Demand Construction holding a Contractor license and 3 other licenses, with the license verified as active as of June 2026 . Separately, BuildZoom records 292 building permits totaling $8,449,100, with recent work including solar photovoltaic roof-mounts and battery installs .
BBB rating: This is the number that should give you pause. The company's BBB file shows an F rating, citing failure to respond to 58 complaints filed against the business and 6 complaints that went unresolved , and Demand Construction Inc. is not BBB accredited . The license on file with BBB has an expiration date of 11/30/2026 , so confirm renewal status as that date approaches.
EnergySage status: EnergySage, one of the larger solar marketplaces, now states Demand Construction is no longer in the EnergySage network , and flags that this installer has not been screened or verified by EnergySage , despite showing a historical 3.5 rating across 225 reviews.
A license being active and a BBB rating being poor are two different things, and both are true here at the same time. Don't let one override the other. Run your own check through the CSLB license lookup tool before signing anything, since status can change between the time a review is published and the day you sign.
Services Offered
Demand Construction's core business is residential solar, paired with battery storage and EV charging. Ancillary services include roofing, HVAC, electrical work, and financing, useful if you want one company handling the whole project, though it also means your roofer and your solar installer are the same crew.
Installer certifications are worth asking about directly. A NABCEP-certified technician has passed standardized testing on PV system design and safety, and asking for that credential by name is a fast way to screen any solar contractor, not just this one.

The Good: Reported Strengths
Even with mixed overall sentiment, a few advantages show up consistently across reviews.
- Bundled permitting and paperwork. ReviewMySolar notes the company handles
permitting and paperwork, including applications, approvals, and interconnection, which is an advantage for customers who need more than just panels .
- One crew for roofing and solar. Because the company handles both trades, panels can be removed and reinstalled during a roof job without bringing in a separate roofing contractor.
- Clean installation work when it happens. One EnergySage reviewer who experienced heavy delays still noted the
work done was very clean and thorough, with panels working great and wiring clean, though delays were the main issue .
The Bad: Documented Complaints
The negative pattern here is specific and repeats across multiple independent platforms, not just one angry customer.
Extreme installation delays. One Birdeye reviewer reported a solar project took 319 days from contract signing to permission to operate , while another described being 330 days into a contract with a 60-day guarantee, with Demand Construction having received over two-thirds of the contract price without fulfilling the terms .
Payment collected before work is finished. A bestcompany.com reviewer described paying 95% of the cost a year after signing with the system still not activated, stating they felt scammed after the company collected two-thirds of payment soon after the contract . The same reviewer noted the company doesn't appear to have its own installation team and uses subcontractors, with everything moving very slowly .
Unresponsiveness after deposit. Other reviewers describe being ghosted once money changes hands. One EnergySage reviewer wrote that after requesting a refund, as soon as they indicated they wanted to cancel and get a refund, the company stopped responding to calls and messages . Another filed a formal dispute after sending a certified letter demanding installation or a refund within 10 business days, which was rejected and sent back unopened, leading to BBB complaints in three states .
Regional and operational limits. ReviewMySolar also lists recurring structural issues: a regional focus primarily in Texas, scheduling delays, mixed customer service responsiveness, pushy sales consultations, limited brand recognition, and extended timelines from combining construction and solar work .

Why Permitting Delays Often Trace Back to Underground Utility Work
Here's something the other reviews don't dig into, and it's worth understanding if you're comparing any solar-plus-construction contractor, not just this one.
One EnergySage complaint described it taking 96 days for the contractor to get plans approved by the city due to errors entering information into the city's plan system, followed by a resubmission to the Houston permitting center months later . That kind of delay is rarely just a paperwork problem. Solar-plus-battery projects usually require a buried conduit run between the main panel, the inverter, and the battery or EV charger, and that means a trench, which means a utility locate, which means another permit layer most homeowners never see coming.
We work this exact intersection every day on the water and sewer side: trenching, utility locating, and site restoration around homes that already have buried gas, water, and electrical lines. A few things we'd flag for anyone signing a solar or construction contract that includes underground conduit work:
- Ask whether the buried conduit run is included in the quote or billed as a change order later.
- Confirm who calls for a utility locate before digging, not just who pulls the building permit.
- Ask how the yard will be restored after the trench is backfilled, not just whether the panels will work.
Federal guidance on trenching hazards, including why utility locates matter before any digging starts, is outlined in OSHA's trenching and excavation safety standards. If a contractor can't answer basic questions about how they'll handle the dig, that's a red flag worth weighing as heavily as the sales pitch.
For homeowners in our own service area who need that underground portion of a project done right, from excavation services and trench digging to water line locating and yard backfilling, that's the piece of these projects we actually handle directly, separate from whoever installs your panels.

Positive Feedback
Satisfied customers most often mention clean installation work once crews actually arrived, and appreciation for the company handling permitting and interconnection paperwork rather than leaving it to the homeowner.
Negative Feedback
Recurring complaints center on month-long and year-long delays, deposits or progress payments collected well before systems were activated, and a pattern of reduced communication once money had changed hands. A Birdeye reviewer summarized months of unanswered follow-ups after a December contract date, noting being told installation would happen by end of December, then pushed to February, March, April, and May before reaching the end of August still waiting .

How to Protect Yourself Before Signing With Any Solar or Construction Contractor
Whether you ultimately choose Demand Construction or someone else, these steps apply to any contractor combining solar, roofing, and underground electrical work:
- Pull the license yourself through your state board rather than trusting a sales rep's claim.
- Ask directly what percentage of the contract price is due before any physical work begins.
- Get the permitting and utility-locate process spelled out in writing, including who is responsible for delays.
- Check BBB complaint text, not just the letter grade, since the details reveal the actual pattern.
- Confirm whether the crew installing your system is an employee crew or a subcontractor, and ask how long that sub has worked with the company.
Final Verdict
Demand Construction may suit homeowners who want bundled solar, roofing, and electrical work under one contract and who are comfortable doing their own verification on license status and BBB history first. The documented pattern of extended delays and post-payment unresponsiveness is serious enough that it shouldn't be the deciding factor you skip.

FAQ
Is Demand Construction still in business?
As of 2026, yes, though EnergySage shows the company is no longer in its network and has not been recently screened or verified by that platform . BuildZoom's license check shows activity as recently as June 2026. Confirm current operating status directly with the company before signing.
Is Demand Construction a legitimate company or a scam?
It holds active contractor licensing according to third-party license trackers, so it is not an unlicensed or fictitious operation. That said, a BBB F rating tied to 58 unanswered complaints and multiple customer accounts describing unresponsiveness after deposit are serious enough that "licensed" and "low-risk" are not the same thing here. Verify license status yourself before paying anything.
Who owns Demand Construction?
A 2024 profile piece named Jorrel Patterson as CEO and Hosep Bahlounian as President , alongside other named executives in marketing and customer experience roles. Leadership can change, so re-verify current ownership through state business registration filings if this matters to your decision.
Has Demand Construction's contractor license been revoked?
No credible source confirms a revocation. BuildZoom's most recent check shows the license as active as of June 2026 , and BBB lists an expiration date of 11/30/2026 rather than any revocation notice. Check the state license board directly for the current status before relying on any review site, since status can change quickly.
What is Demand Construction's BBB rating?
The company's BBB profile shows an F rating, driven by failure to respond to 58 filed complaints and 6 unresolved complaints , and the business is not BBB accredited.
Is Demand Construction the same company as Nation Energy Services?
They share the same San Fernando business address and overlapping branding under "Demand Solar," based on public business listings. Nation Energy Services' Yelp page lists the business as established in 2020, serving California since 2019 under the same CSLB, Texas, and Florida license numbers referenced by Demand Construction listings . If you're researching complaints, check both names.
