I designed, installed & probably over-engineered it to cover just about every nook, cranny, staircase etc.

@Alexis Morleand I’m a structural engineer and have designed and managed construction on hotels similar to the one you are considering developing (Most recent hotel was $25 million Marriott with 180 rooms in Los Angeles).

I'm wondering if I should even pay to get my license now though since I'm not planning to go full time, I really do take part in the industry.I currently have a full time job as a data engineer and do very flexible as-needed gig jobs (sign up for shifts) like valet, photographer assistant,  DoorDash, Uber, etc. 

Spend the money and have an acoustic engineer soundproof?

The cost to grade it will vary depending on a concrete demo then grade, meaning you will have some engineering cost to include soil testing, Surveying cost and a list of other test before the land is construction build ready. 4) What about the Architecture cost, Are you buying one of those already designed Duplex plan kits?

Since the I have had it cleared, soil work done, survey done, civil engineer is almost complete and I am looking for an architect.

in that sense I can think of the ideal landlord-tenant relationship as one of mutual benefit, with some goals aligned and some differing.My goal is tenants to  adhere to the contract, I do my part, they pay on-time, I have a good relationship with them (I don't tell them I'm a LANDLORD, I tell them I'm a civil engineer, an employee working for someone else, and that I have been a tenant so many times before).  

I am 18 and currently attend University of California, Irvine and am studying Civil Engineering with specialization in Structures.

If you have habitual problems where every other month you are claiming some kind of issue then they might deny giving you a credit.I have talked to engineers at the water department before and they have water flow and usage down to a science.

The foundation cement structure and bolts and septic tank and leach field and block walls were left remaining.I had to have an engineer certify that the cement was intact and could be built on.
