Getting ready to built this detached shop. Should the finished concrete be on grade with the existing home, at the height of the carport and patio. Or maybe in between? This is in Tempe Az so no real flooding issues. Existing home is elevated about 8” off the soil grade. In the back yard.I marked up your site plan.
I’d try to put a garage door to the alley.It’s only 20’ wide so maybe on shop’s left side and maybe angle vehicles in. For grade, I’d make darn sure you avoid water problems.I marked up your site plan.
- In orange, it shows the over head electric (OHE). Typically the power company has an easement for this and will not want their service drop in near conflict with your proposed garage. In my area, for underground power easements (not sure about overhead easements) they are typically 10-15' wide and the power company puts their service anywhere within that region and then everybody else has to stay 3' away from it and (if an exclusive easement), no one can be in the remainder of the easement. So if the service were literally installed on the edge of the easement (happens quite a bit), then all other encroachments to the service must stay 3' away from the installed service.
- In red, it shows the building restriction lines (BRL's). On the left side it shows you have a 10' restriction and on the alley side, it shows you have a 15' restriction. In essence, no structures are allowed to be within the lot perimeter and the BRL line. You have encroached well within the 10' BRL on the left side and at the alley, you are building right up to the property line. I presume you have obtained a variance for this as normally this would not be allowed in my area.
- As to your hobby shop slab elevation question, is this a garage with a garage door off the alley, or just man doors from the house side?
- If there is a garage door from the ally, then the existing ally elevation will determine your slab height so you can have a gentle ramp approach into the garage and not bottom out.
- If just man doors from the yard, I would set the slab perhaps 6-8" above the existing finished grade so you have one step down to grade. Remember, your sill plate needs to be 8" from soil line.
Is he/she a registered architect, or a draftsman?
yes I agree. That had been an issue on a previous plumbing repair also. The city record shows the ally being 10’ wide when it is actually 20’.
The contractor has very little to do with the design, he builds to the permitted drawings. He should be a resource to give advice, but it’s not his job to research codes and ordinances.
You don’t know what you are talking about, and the “architect” you are dealing with doesn’t know much better. See this plan? The red circle show survey info for your property line. That’s the end of your yard. The blue circle … says public alley. You really should hire a competent professional.
