I got to know Uni through its five star ratings. Just as the reviews say, Min always responds to my requests quickly, and helps me revise the plan many times until the permit application is approved. Highly recommended!! Trust me, you won't regret using their services.

I highly recommend Uni Construction for architectural plans. They did a great job on my plans for a detached ADU and getting them fully approved by the city. The plans were done quickly and you can trust that the job will get done right. I will definitely use them again for future projects.

Min has been extremely helpful in helping us create plans for our project. From even before we committed to Uni, Min provided guidance and advice on what to look for when getting other quotes and how to approach things. After we started the project, Min has been quick to respond and even pushed for us to get a quicker turnaround time than anticipated, we’re grateful for the team at Uni and will continue to use their services for future projects

Find More Pros

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

To find more licensing information for your state, visit our Licensing Requirements page. Note that some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

HomeAdvisor's Screening Process

HomeAdvisor uses an extensive screening process to screen businesses and business owners/principals. We perform this screening when a business applies to join our network and, if the business is accepted, whenever concerns are brought to our attention. If you have concerns that a pro in our network doesn't meet these standards, please contact us to investigate. We're committed to maintaining a network of trusted home service businesses, and those who don't meet our criteria will be rejected or promptly removed from our network.

Criminal Background Check

Who does HomeAdvisor background check?

The owner or principal of each business in HomeAdvisor's network (with the exception of Corporate Accounts) must pass a background check. Unfortunately, we cannot perform a background check on every employee of a business—the background checks are performed only on the owner or principal. As always, we recommend that you conduct your own research on the businesses you hire, including making inquiries directly with the businesses regarding their employee background check policies.

What does the background check cover?

We use a third-party vendor to conduct a criminal records search in the county in which the business owner or principal works. Our third-party vendor uses a national criminal database ("NCD") to screen service professionals. Business owners or principals with felony arrests that carry a pending decision or who are convicted of felonies in the past 7 years ago will not be admitted to the network. Businesses or owners convicted misdemeanors or felonies, or who have dismissed charges or arrests on their records involving rape/incest, sex offenses, or lewd and lascivious behavior at any point in time will not be admitted to our network.

Our background check does not exclude service professionals unless the crime at issue is a felony.

*The comprehensiveness of the NCD varies by state. Please be aware that the reporting in the NCD is particularly limited in the following states: AL, CO, DE, GA, ID, IL, KS, LA, ME, MA, MI, MS, MT, NE, NV, NH, NM, SD, UT, VA, VT, and WY. After initial admission to the HomeAdvisor network, businesses are re-screened if a concern is reported to HomeAdvisor.

Corporate Accounts

Some businesses are employees, franchisees, dealers or independent contractors ("Corporate SP's") of larger national or "Corporate Accounts". When this is the case, we may match you with the Corporate Account or with one of their Corporate businesses. The above screening process does not apply to Corporate Accounts, as HomeAdvisor does not screen Corporate Accounts or Corporate businesses.

Verify Trade License HomeAdvisor checks to see if the business carries the appropriate state-level license. Verify Insurance As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services. Verification of State Business Filings For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located. Criminal Records Search HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business. Sex Offender Search We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located. Bankruptcy Search We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them. Legal Search for Civil Judgments We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them. Liens Search We use 3rd party data sources to check the principal/owner of the business for liens placed against them. Identity Verification (SSN) HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities. Identity Verification (Reverse Phone Lookup) We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
