Well, I generally get $0.60 to $0.90 depending upon how much the client grates on my nerves when we first meet.... the ones that are decisive, typically get the better rate....I never quote a PSF price...
the typical scenario is...
Client contacts me for plans, wanting quote...
I review their (typically) hand drawn plans and then based on our "interview" process I make a determination on whether this client is likely going to require a lot of changes....
I quote based on our interview typically $0.80 PSF for a set of plans that consist of
a) Four exterior elevations
b) Electrical plans
c) Dimensional plans
d) Floor framing plans
e) Roof Framing plans (if not provided by truss mfg)
f) Foundation plans
g) Sectional
h) Details as needed
i) Cover sheet w/index
I do all of the design work, sizing beams, joists, rafters, foundations, rebars, uplift requirements, point loads, fireplaces, and any other custom things the client wants or requires. I can do this typically in a couple of days and be done.
I also handle the contact with the engineer of record, who provides, structural analysis, wind load analysis, and energy calculations.
In perhaps the last 2 years that I have been doing this, I could probably count the number of deviations the engineer required on one hand....I do it all....
I can do the plumbing design, DWV and supply, but will add an additional $300 for those alone (I don't like them and if the client is willing to pay, then I am glad to take their money)
My engineer charges me $300 per plan, and my paper/copy cost is $1.00 per page...typical plans require 10 - 15 pages. The client gets 5 sets ... 3 will be sealed, 2 are for subs and general reference...they get additional copies at their expense.
I don't design interiors i.e. cabinets etc... I tell them to let the cabinet people do that...take the preliminary plan and go to a cabinet shop and have them design it for them...I'll show any deviations IF they get them to me before press time...
Changes AFTER the seal is applied are charged at $500 per event and $25 per page... typically they decide to do a field amendment...
All preliminary work is charged at $150 and includes only the basic plans and front elevations. Additional charges are incurred if the client requires all 4 elevatios from the beginning. All funds paid in the preliminary process is fully aplied to the final set of plans.
Dangit ... didn't realize it was that much info ... typical house for me is $2400 plus engineering fees... is that ok? too high? too low?
