If you are looking to remodel, expand or sell your home, there's a good chance you will have a close encounter with your local building code. These laws can be extensive, confusing and change frequently. The code is there for your safety, but it can still be frustrating to deal with. Older homes in particular are likely to have outdated technology that wouldn't pass a current inspection. Before embarking on a project, take time to understand what the laws are and how they can affect you.

What Is Building Code?

Just about anything you want to do to your home beyond cosmetic changes probably has a corresponding law. Building code covers a number of standards mostly related to safety, including but not limited to HVAC, the electric system, plumbing, the structural integrity of the building and fire safety. If you own a rental unit, there are probably additional standards that you are required to meet before accepting tenants.

Of course, specific housing codes vary by municipality, although most are based on models like the International Residential Code and the National Electric Code. Go to your city or town  website or visit the building department for more information. You can also look up many city and municipality codes from around the country on a website called Municode.

Is My Old Electric Wiring Safe?

The electric code is one of the most important pieces of building code, because failing to comply can endanger your home and property. Some common violations include improperly sized connections, overfilling outlet boxes, not properly grounding and not spacing outlets correctly.

Many code problems require only a simply fix, but others can be a much bigger undertaking. For example, old houses may conduct electricity on knob and tube wiring, which became obsolete in the 1940s. This type of wiring can put your home at risk and isn't equipped to handle high power loads typical in modern homes. If you still have knob and tube, you may discover an expensive upgrade is necessary when it's time to sell the house.

The laws governing electric systems are complex and confusing to many homeowners. The national code on which most cities base their own laws is 1,000 pages long -- far more than the average home DIY-er is able to digest. You could inadvertently run afoul of the law by doing something as simple as replacing a light fixture without upgrading the wiring to the most recent standards. It’s wise to consult a qualified electrician before undertaking a project  so you don’t find yourself in over your head – and on the wrong side of the law.

What if I'm Out of Compliance? 

If you have an older home that doesn't meet the current laws, don't panic. Usually older buildings are grandfathered in when the codes are updated. However, if you want to modify or replace parts of the house, you might be required to do additional work to bring any outdated aspects into compliance.

Do your research so you understand when you need to pull a permit or bring in a city inspector. Talk to local officials up front so they can help you understand how to proceed. When in doubt, hire a qualified professional experienced in local housing laws to let you know where you are up to code and in what areas you fall short.

LED sign lighting provides years of illumination and low energy costs. sign modules that consume 50mA of power each. Required materials differ depending on sign size, module size, length of wire between modules, current draw, and lumen output.

Materials:

1. First, measure your sign. Although we recommend spacing module rows 3 inches apart, it’s ultimately up to you. If you want a brighter sign, place them closer together and vice versa for a dimmer sign. With the recommended 3-inch spacing, a 4-foot square sign would need 150 modules (15 rows of 10). Again, the quantity of modules needed  is based on many factors and can differ.

These LED sign modules are available in custom lengths of up to 20 modules per strand. Order 60 feet (4 feet x 15 rows) of stranded modules, and cut the strand after every 10 modules. Each strand can be cut to make two rows.

2. Next you’ll need to order a power supply that’s rated for the combined wattage of all sign modules. To ensure that you don’t overwork the power supply, confirm that the total wattage of your modules is at least 20 percent less than the power supply’s rated wattage.

An easy way to calculate this is to multiply the total wattage of your combined lighting by 1.2. In the 4-foot sign diagram, there are 150 modules with a current draw of 50 milliamps (mA) each. Since current draw is given in milliamps, multiply that number by voltage and move the decimal 3 places to the left to get wattage. This module consumes 50 mA and has 12 VDC operation, so it consumes 0.6 watts (50 x 12 = 600). Next, multiply 0.6 by 150 to get a combined wattage of 90 and multiply that number by 1.2 (90 x 1.2 = 108) to determine which power supply you’ll need. Since the result was 108, you will need at least a 120-watt power supply.

3. Next on the list is wire to connect all your sign module stands to the power supply. For a 4-foot sign, you’ll need 4 feet of 18-gauge two-conductor wire to serve as your main line plus enough to cover the distance between your power supply and where it will be wired into an electrical system. You’ll also need dual-channel T-tap wire splice connectors for an easy connection to your main line.

Before you begin working on your sign, turn off power to the area.

4. If there isn’t one already, drill a hole in the back of your sign as an exit point for your wire.

5. Use a tape measure or ruler to plot your row spacing. Leave space on one side of the sign for your module-to-main-line connections. Mount the sign modules using their double-sided adhesive and/or screw holes.

6. Insert the end wires of each sign module row into the T-tap splice connector, and clamp the other end of the connector onto the main line. The splice connectors eliminate the need to strip wire insulation.

7. Use double-sided foam tape to secure each T-tap splice connector to the inside of your sign.

8. Reattach your sign’s front cover.

9. Connect the main line to your power supply, wire the supply into your electrical system, and restore power to the area.

Being a home owner comes with more responsibility than some people realize, and it can get overwhelming. There are certain aspects about your home that you may have overlooked, or just thought wasn’t important, like your HVAC system. Not paying attention to your HVAC can become very troublesome for your home and cause several issues.

While some might think of a garage as simply another room where you park your car and use as storage, it’s still part of your home and could be the cause of a higher energy bill. Helping make your garage more energy efficient will in turn lead to higher energy savings for your home.

Find out how to keep your garage energy efficient while saving money with our simple tips.

By insulating your garage and garage doors you can help keep the use of your HVAC down during the cold months. Garage doors tend to have several openings from which cold air can go through, causing the HVAC system to kick in more frequently than usual.

Turning down the temperature of your water heater to 120° F helps keep the water comfortably warm while reducing on unneeded energy waste. Lowering down the heat while on vacation also results in lower energy consumption.

Other tips for your water heater include purchasing a unit with a high Energy Factor (EF) rating that is more energy efficient, and routinely draining a bucket of water to help remove sediment that could cause issues.

Using warm or cold water instead of hot water to wash your clothes helps save energy up to $50 per year. Consider also investing in a front-loading washing machine, which use less water on average than traditional models.

When using the dryer, make sure to add a dry towel to help reduce the drying time. Keep yourself from running an additional cycle by not overloading your washer and dryer, which will cause your clothes to not be cleaned properly, and take significantly longer to dry. Cleaning the lint screen after every load helps keep the exhaust clean while reducing drying time and energy usage.

With the rise of energy efficient electric cars comes the need to keep a steady supply of fuel at home. Electric vehicle charging stations are a good choice, but oftentimes a faulty installation could lead to more serious problems down the line if installed incorrectly.

Having a professional and qualified electrician install EV chargers helps ensure that the correct voltage is being used and that the amperage will work best for your needs. They will also help you choose the correct model so that the installation location fits the length of the charging cable.

Garages are the perfect place for a handyman’s work station or home office and as a result, many might have power tools and various other electronics connected at all times.

As we mentioned in our energy guide for the living room, vampire appliances could result in wasted energy and time on standby mode. So if you’re using power tools or any other electronics, make sure to unplug them after use to help keep the costs down.

Light bulbs usually consume more electricity than an LED so replacing them is a wise choice. LEDs not only help reduce your carbon footprint, but they also need to be replaced less frequently and consume less energy making them a perfect energy efficient option.

Often times, the lights will be left on as you forget and move to other rooms in your home so consider investing in a light timer which can automatically turn the light off after a set amount of time.

While having a spare refrigerator or freezer in your garage might be a good idea for keeping spare food safe, it’s often wiser to get rid of it or replace it with a more energy efficient model.

If you’re not ready to get rid of the appliance, at least unplug it to help keep unneeded energy from being wasted.
