I was in your shoes. The building dept office didn't like anything I drew up, despite repeated attempts. They want to deal with their regular local builders. That's when I caved and got a GC. With that came all the direction for lot survey, a reputable local designer, cheap engineer (one stupid tall wall needed $500 signature), etc.
Anyway, got the GC to do the basic 'heavy lifting' to have an enclosed dry structure and dismissed him. Then I DIY'd the easier stuff (for me) like insulation & vb, boarding, garage door, electrical, etc.
We also hired a GC to dry it in and we finished the inside .
GC was fine with that .
Had a hard time finding a GC willing to do such a “small “ job though but the guy we wound up with , was about the third one reccomendd by the architect , was a great guy .
And very transparent , his fee was 10% of the cost , and he didn’t hide any invoices , most of the time he gave us the invoices and we paid his subs directly , eliminating the possibility he was severely up charging us , unless he was getting kickbacks from the subs after we paid them .
The GC got the permits and was there for all the inspections,
We had a lot of issues with weather and Covid suplly chain issues but that wasn’t the GCs fault
A local GC will have a lot of subs to use and knows which ones are reliable etc
The GC we used had six or seven houses going at any one time so kept the subs busy about half the time just with his own houses
And he didn’t do any spec houses , just remodels and custom builds
he got the grading done and the footers excavated and during Covid there was a six week lead time to get concrete, and if it rained too hard on your appointment day for your crew to do the work , you got bumped to the bottom of the six week waiting list since tomorrows concrete had already been promised to
Someone else six weeks ago .
Of course it rains on our appointment day , so a six week delay ,
That was for thw footers , then for the walls , it rained on our appointment day so a six week delay where nothing got done ,
Then it rained again on the appointment day for the slab ,
Took four months to get the foundation and slab in
Then since ours had a bend in the middle the company making the roof trusses wanted to measure it themselves , after the walls were up , then three weeks to get the trusses manufactured,
The day before our trusses were to be delivered , the warehouse caught fire and destroyed our trusses , so another six weeks to get new trusses .
Then the framers wanted ti use a crane to set them , so the GC has ti find a day when the crane company and the framers and the power company are all available since the crane operator required our power line to be taken down ,
So the day arrived and everyone is on site and it rains a little , crane operator heard some thunder and said he wasn’t gonna do anything and left .
So another four weeks to get everyone back out .
grading was done in feb
Walls got poured in mid March
Floor got poured mid April
Roof trusses got set at the end of July
Got all the siding done mid December
Not sure when the Sheetrock got done
Took about another 18 months for us to get the electrical and plumbing and insulation install the hardwood flooring
