One Lot, Four Drawing Sets: Staffing a Compound Project
Share this article
Key takeaways
- A compound on one lot, a main residence plus an ADU, a garage or guest house, and sometimes a pool house or site package, is several projects for drafting and permitting, not one larger house.
- Each structure on the lot gets its own complete drawing set and its own review path, so the sets often move through plan check on different clocks.
- The staffing problem a compound creates is sheet count, not square footage: four modest structures can need more drafting hours than one large house of the same total area.
- Firms that staff for 'one project' end up buried once several sets are active at once; the fix is drafting capacity that scales with how many sets are actually in production.
A compound puts a main house, an ADU, and a garage or guest house on one lot, each needing its own drawing set. Here is how firms staff for sheet count, not square footage.
A Compound Is Not a Bigger House
One lot, several structures: a main residence, an accessory dwelling unit, a garage or guest house, and sometimes a pool house or a separate site and civil package. On paper that reads like one project with a bigger scope. On a drafting schedule it reads like several projects that happen to share a property line.
That distinction matters because a firm staffs for projects, and a compound is not one project sized up, it is multiple projects running in parallel on the same lot. Treat it like a bigger house and the drafting team ends up short exactly where it counts: sheet count, not square footage.
What a Drawing Set Actually Includes
A complete architecture drawing set commonly combines site plans, floor plans, elevations, and sections, because each sheet answers a different question about the same building: where it sits, how it is organized, what it looks like from outside, and how it is built in section.
That combination is produced once per structure, not once per lot. A main house gets its own full set. An ADU gets its own full set, even though it is smaller. A garage or guest house gets its own full set too, scaled to its size but not skipped. Four structures on one lot can mean four separate sets moving through drafting and review at the same time.
Why One Lot Can Mean Four Separate Permit Paths
Each structure on a compound lot is typically reviewed on its own permit path, with its own submission, its own plan-check comments, and its own clock. ADU permit timelines are unpredictable, your staffing shouldn't be covers how much that timeline can vary for a single accessory unit. On a compound, that same variance applies separately to the main house, the ADU, and any additional structure, often with each one clearing review at a different point in the schedule.
That means a firm is not managing one review cycle with a longer list of comments. It is managing three or four review cycles at once, each with its own redlines, its own resubmission, and its own deadline pressure landing at an unpredictable moment relative to the others.
Where Compound Staffing Breaks: Sheet Count, Not Square Footage
The mistake most firms make is sizing the drafting team to the combined square footage of the compound, the way they would size a team for one large house. A 6,000 square foot single residence and a compound made of a 3,500 square foot main house, a 700 square foot ADU, and an 1,800 square foot garage with living space above can land at similar total area, but the compound needs roughly three times the sheet count, because each structure carries its own full set of site, floor, elevation, and section sheets regardless of size.
A team staffed for square footage runs fine on the single residence and falls behind on the compound, not because the drafters are slower, but because there is simply more to draft, review, and resubmit across more simultaneous permit paths.
How to Staff Drafting Capacity That Scales With Sets in Production
The fix is staffing to the number of sets actually in production at a given moment, not to the project as a whole. That means adding drafting capacity when the ADU set, the main house set, and the garage set are all moving through production at once, and scaling that capacity back once a set clears review and moves to construction documentation or closes out.
WorldTeams staffs drafting and technical capacity for more than 370 companies in the US and Canada, matching firms with professionals who are screened to the top 3 percent of applicants before being placed on a team, as outlined in 5 key architectural services your firm can offer with outsourcing. Each engagement gets a dedicated account manager, which lets a firm add or shift drafting capacity per set in production instead of running a single hiring cycle sized for a project that is really several projects on one lot, the same scaling logic covered in achieve architectural efficiency by embracing outsourcing.
Onboarding a pre-vetted drafter typically takes less than 72 hours once a firm shares its standards and the sets currently in production, and every placement carries a two week replacement guarantee, so adding capacity for one structure's set on a compound does not require committing to a permanent build-out of the team.

Frequently asked questions
Answers to the questions readers ask most about compound project staffing.
Why does a compound on one lot need more than one drawing set?
A compound is not one building, it is several: a main residence, an accessory dwelling unit, and often a garage or guest house, each sitting on the same lot but reviewed as its own structure. What a drawing set actually includes covers why each structure needs its own complete set rather than sharing one, and state-level ADU rules confirm an ADU is treated as a distinct unit for permitting purposes in most jurisdictions.
How many separate drawing sets does a typical compound project need?
A compound with a main house, an ADU, and a garage or guest house typically needs three to four full sets: one per structure, since a complete drawing set combines site plans, floor plans, elevations, and sections for one building, and that combination gets produced again for each additional structure on the lot.
Does each structure in a compound need its own permit set?
In most jurisdictions, yes. Each structure is reviewed on its own timeline, which is the same pattern covered in ADU permit timelines are unpredictable, your staffing shouldn't be: a compound just multiplies that unpredictability by however many structures are on the lot, as explained in why one lot can mean four separate permit paths.
How should a firm staff drafting capacity for a compound project without over-hiring?
Size the team to the number of sets actually in production, not to the project as a whole. How to staff drafting capacity that scales with sets in production walks through adding or shifting drafting and technical capacity per set instead of running one hiring cycle for a project with several structures, a model also covered in 5 key architectural services your firm can offer with outsourcing.
Can a flexible drafting team start on a compound project quickly?
Onboarding for a pre-vetted drafter typically takes less than 72 hours once a firm shares its standards and the active sets, and every placement carries a two week replacement guarantee, so a firm can add drafting and technical capacity for one structure's set without committing to a full build-out of the team, as covered in how to staff drafting capacity that scales with sets in production.
