Albuquerque, New Mexico

540 sq ft casita
with a single-pitch metal roof

Eighteen by thirty, drawn for a specific Albuquerque lot rather than pulled from the city's set. It is the plan the June 2026 quote on this site was written against, so its shell price is the quote itself and not a rate applied to a different size. The trade-off is real: the city's drawings are free and this one's are not, and the permit goes through the structural review a pre-approved plan skips.

A standing-seam metal shed roof with a deep front overhang and a continuous band of clerestory glass under the high side. More daylight and more shade, for a little more money.

The number

What this plan costs to build.

Every dollar below traces to a line item, anchored to a June 2026 Albuquerque contractor quote instead of a national average. This is the one plan on the site the quote was actually written for: the shell line below is that quote, not the rate applied to a different size. The drawings are a real line here, because the city only publishes its own.

All in, on an easy lot $145,015 Design, permits, construction, and contingency. About $269 per finished square foot.
On a harder lot $166,075 A long utility run, a new sewer connection, a tight gate, a slope, and an old slab to clear. Most lots land between the two.

The five lot questions move this number more than anything else, and a website can't answer them for you. The configurator asks them and reprices as you go.

Permit to keys

How long this takes.

01
Design and site plan

Pick a plan, walk the lot, and get the plot plan and grading drawings drawn against the pre-approved set.

2 to 4 weeks
02
Permit

Site Plan - Administrative review, public notice, then the building permit through ABQ-PLAN. Pre-approved plans skip the structural review that eats most of this window.

4 to 10 weeks
03
Site work and foundation

Clear, trench the utility run, form and pour the monolithic slab.

2 to 3 weeks
04
Frame, dry-in, rough-ins

2×6 walls at 16" on center, roof, windows and doors, then the trades.

4 to 6 weeks
05
Finishes

Insulation, drywall, stucco, cabinets, floors, fixtures, paint.

5 to 7 weeks
06
Inspections and keys

Final inspections, certificate of occupancy, walkthrough.

1 to 2 weeks

Step two runs longer on this plan. The pre-approved set is what lets a permit skip the structural review, and a custom plan does not skip it. Budget the top of that four to ten week range, not the bottom.
