Do you need a permit to install a patio cover?

Every city and county can have different requirements but here is an example from the San Diego Building code for you to refer to. We always recommend that you check with your local codes to ensure you are compliant. Your local J&W Lumber can help you find out if you are up to your local code.

Patio cover structures that do not exceed 300 square feet of projected roof area may be exempt from a building permit in single family residential zones. Although such patio covers may still be exempt from building permit, they are not exempt from electrical, plumbing, mechanical permit requirements and other building regulations (SDMC 129.0203(a)).” Building permits for any new patio cover or repair or enclosure of an existing patio cover will be required if any of the following conditions occur:

  1. The patio structure is located on a site that contains environmental sensitive lands.
  2. The patio structure encroaches into any required side yards or established setbacks.
  3. The property is located in the Coastal Zone or any site regulated by a Planned Residential Development (PRD) permit or Planned Infill Residential Development (PIRD) permit.”

Do termites eat Redwood?

Redwood is a natural deterrent to termites. It is the “heart” of the redwood that is a repellent. The Sapwood or white part of the redwood board is not as resistant and fair game. Look at these pictures of termite damage on redwood. You will notice the “heartwood” is not even touched.

How long does stain last before it needs to be re-applied?

Depending on your deck’s exposure to direct sunlight and precipitation elements, for Fir, Cedar and Redwood we recommend re-staining every 2-3 years.

The harder the wood the more frequent the applications will be needed IPE and Mangaris may need to be re-stained every year. With the oil stains we sell follow the rule of thumb that Less is More. If you over-apply the stain the results can remain tacky and attract dirt.

What is the actual size of surfaced lumber?

Nominal sizes are not the same as actual or net sizes… Softwood lumber is customarily referred to by nominal sizes such as 1×6, 2×4, 4×4 and so on. In these descriptions, the first number represents the thickness; the second number represents the width. It is important to note that what we call a 2×4 or 1×6 is usually a piece of lumber smaller than it’s nominal size. For example, a smooth Redwood 2×4 would measure 1-1/2″x3-1/2″.
