Commercial Remodeling & Building Renovation – Complete Guide

 March 21, 2019

A commercial remodeling or building renovation project is both exciting and a bit worrisome.  You might be a business owner looking to expand or modernize your store space.  Alternatively, you might be a developer or investor who sees the enormous potential in renovating tired, run-down or out-of-code properties.  Happily, once you fix them up, you can either sell them (the classic fix-and-flip), or hold them for rental income.  Either way, you need to understand how commercial construction and renovation works.  You need to know how to select a good commercial renovation contractor.  How much will you spend on commercial renovation cost per square foot? Where can you obtain financing for renovating a building? If you read on, we’ll answer all these questions.

Commercial Construction and Renovation

Building renovations vary in complexity.  Specifically, some are only skin-deep, while others require changes that go down to the core structure.  Unsurprisingly, your costs will directly depend on the renovation’s scope.  Obviously, to get a handle on the size of the project, you need to do preliminary planning and work.

Preliminary Work for a Commercial Building Renovation

If you already own a commercial space, either as a landlord or as a business owner, you probably already have a handle on some preliminary work for commercial remodeling.  But, if you are an investor looking for suitable properties to buy, you have much preparation work to do, including:

Check the Certificate of Occupancy (CO)

In a commercial renovation, the CO will tell you whether the property meets applicable building codes.  Specifically, the list of violations, often available online, will reveal much about the scope of the work.  For example, a tall abandoned building that needs extensive asbestos remediation is a bigger project than one that doesn’t. 

Consequently, the purchase price should reflect this.  Bear in mind that you will need an inspector to sign off on every building violation that you fix.  In addition, the CO describes the approved use(s) of the building consistent with the local zoning ordinances.  It further tells you whether the building is suitable for occupancy.  Unfortunately, changing the permitted use of the building might be a hassle.  So, you might want to work with an expediter.  Keep in mind, an expediter knows the local politics and should be able to expedite the process.

Apply For Financing


Work with Your Architect and Engineer

If you like the property, walk through it with your architect, engineer and general contractor.  That way, you’ll get a handle on the amount of work and money it will take to correct the code violations and to reconstruct the building according to your vision.  Not surprisingly, some professionals will do this as a courtesy in hopes of landing your business. 

If the renovation is extensive, the engineer will verify that the property will physically and operationally handle the changes ordered up by your architect.  For example, let’s say that you intend to repurpose a clothing store to one selling appliances.  Your engineer will determine the requirements to reinforce the floor.  In general, you’ll want to assess the property’s mechanical, electrical and plumbing systems.  Also, the engineer will categorize walls as to whether they are load-bearing and structurally sound to handle additional weight.  In fact, your team will survey many details to establish the total scope of the project and its associated costs.

Solutions, advice, secrets, and tips for commercial remodeling of distressed property

Inspect the Building Envelope

The building envelope includes its external walls, roof, doors, windows and so forth.  Keep in mind that the structure might date back to a time before mandatory handicap access.  Therefore, you might have to reconfigure spaces to accommodate the disabled.  This might include converting steps to a ramp, enlarging doorways, updating bathrooms and much more.  Also consider whether the property resides in a historical district, or is itself a landmark.  Unfortunately, this can tie your hands regarding what changes you can make to the building.

Understand Health Code Requirements

Are you turning a store into a restaurant? Well, you’ll need to satisfy the health code laws, including the possible need to install additional bathrooms.  In fact, that’s just one example of the many possible challenges the local health codes may present.  Happily, your expediter can help you understand the rules and how you can satisfy them.

Commercial Renovation Contractors

The law requires most commercial renovation projects to hire a commercial renovation contractor to oversee the work and ensure it proceeds correctly.  The general contractor, or GC, hires subcontractors, manages the building supplies, and makes sure that all work passes inspection.  In general, the commercial renovation contractor makes sure the project runs smoothly.

What to Look for in a Commercial Renovation Contractor

If you are new to commercial construction and building renovation, you might need to select a general contractor.  And you might be doing this selection for the first time.  Since you don’t have previous experience, you’ll need to rely on the recommendations of others.  And, of course, you’ll need to conduct your own due diligence as well.  This includes:


You will likely invite several GCs to bid on your project.  Specifically, each contractor will provide a bid package containing the plans, costs and timelines for the projects.  Interestingly, one way to judge a bid is its level of detail — the more detail, the better.  Without a doubt, you must ensure that all the GC candidates bid on the same set of requirements.  You’ll do this so that you can properly compare apples to apples.   Moreover, note any work the GC excludes from the project.


You must ensure that your GC is a fully licensed commercial contractor.  Usually, this is a state and/or local requirement.  Without fail, the GC should carry a significant amount of insurance.  Therefore, you should verify the insurance policies that the GC owns, directly with the insurance company.  Doubtlessly, the amount of coverage can greatly vary among contractors, so make sure the candidate has sufficient coverage. 


It’s a clever idea to hire a commercial renovation contractor that you trust.  Importantly, one key factor is assessing the contractor’s communication style to see if it meshes with yours.  Usually, this includes frequency and type of communication as well.  For example, you might prefer daily oral updates or weekly written ones.  Truthfully, if the contractor has trouble agreeing to your communication needs, you might want to keep looking.


Does your project include highly specialized or unusual features?  For sure, a commercial renovation contractor with applicable experience is a valuable asset and worth paying a premium.  Therefore, you should verify a GC’s experience by following up with some of the principals on previous deals.  If possible, personally inspect the GC’s work and speak with the current property owner. 

Commercial Renovation Cost Per Square Foot

Your budget requirements often boil down to commercial renovation cost per square foot.  Unfortunately, costs can vary wildly depending on the project details.  Nonetheless, experience indicates certain average costs.  Generally, you should expect to pay $100 to $200 per square foot for new construction.  Furthermore, your cost for commercial remodeling will probably run about $50 to $150 per square foot.  In truth, these are, at best, ballpark figures that can differ greatly.  For example, the cost varies due to location, features, building use, building codes, historic district compliance.  Further variation factors include any special disciplines required, and other current market factors, including labor costs.  Without fail, don’t forget to include additional soft costs for project specialists, such as the architect, expediter and engineer.

Ronny was a pleasure to work with and is extremely knowledgeable. His hard work was never ending until the job was done. They handled a complex lease and guided us through entire process, including the paperwork. Not to mention a below market lease rate and more than all the features we needed in a site. We later used Assets America for a unique equipment financing deal where once again Ronny and team exceeded our expectations and our timeline. Thank you to Assets America for your highly professional service!

Highly recommend them for any type of commercial financing

My business partner and I were looking to purchase a retail shopping center in southern California.  We sought out the services of Ronny, CFO of Assets America.  Ronny found us several commercial properties which met our desired needs.  We chose the property we liked best, and Ronny went to work. He negotiated very aggressively on our behalf. We came to terms with the Seller, entered into a purchase agreement and opened escrow.  Additionally, we needed 80 percent financing on our multimillion-dollar purchase.  Assets America also handled the commercial loan for us.  They were our One-Stop-Shop. They obtained fantastic, low, fixed rate insurance money for us.  So, Assets America handled both the sale and the loan for us and successfully closed our escrow within the time frame stated in the purchase agreement.  Ronny did and performed exactly as he said he would. Ronny and his company are true professionals.  In this day and age, it’s especially rare and wonderful to work with a person who actually does what he says he will do.  We recommend them to anyone needing any type of commercial real estate transaction and we further highly recommend them for any type of commercial financing.  They were diligent and forthright on both accounts and brought our deal to a successful closing.
