Most postwar South Portland houses have no drawings anywhere, so an addition starts with measuring what is already standing. Plans here begin at $1,250 flat, and a measured existing-conditions set usually comes back in about a week.
Whole streets off Meetinghouse Hill went up fast on a few repeated layouts for shipyard workers, and the paperwork served the builder, not you. Porches got closed in and basements got finished, so even a surviving original set would describe a house that no longer exists.
Someone measures room by room, photographs the panel and the attic hatch, then drafts plan and elevations at scale with your proposed work shown alongside the existing. This is drafting and design work, not architecture: no architect's seal and no structural engineering unless you step up to that tier. Two revisions are included, and city comment rounds are not billed.
How does an existing house get measured and drawn?
The process is more ordinary than it sounds, and knowing the shape of it makes you a better client.
Somebody comes and measures. Room by room, wall by wall, running dimensions rather than a tape held once per room, so that small errors do not add up across the building. Window and door openings, ceiling heights, stair rise and run, the outside envelope.
They photograph everything, including the parts nobody looks at. The basement, the attic hatch, the panel, the meter, the outside of every wall.
Then it gets drafted into a plan and elevations, dimensioned, at scale. That is your existing conditions set.
Your proposed work is drawn on top of it, and the good sets show both. Existing and proposed, side by side, so a builder and a reviewer can see exactly what is changing.
Two South Portland details worth naming. Wide flat lots mean access is easy and a measuring visit is quick, which is genuinely not true across the bridge. And the winterized cottages at Willard Beach and Ferry Village are the harder ones, because seasonal buildings were added to in stages and almost nothing in them is a single construction.
Have the basement clear and the attic reachable on the day. An hour of moving boxes beforehand saves a second visit.
Say what you think you want before the visit, not after. Somebody measuring a house for a kitchen job looks harder at different things than somebody measuring for a second-floor addition, and a rough idea of the goal makes the field work sharper.
Expect the drawing to disagree with you about a room. Almost every set turns up something the owner had wrong, usually a wall that is not where it feels like it is. That is the process working rather than failing.
Your code office reviews the proposed work against what is there now, so ask the City of South Portland whether they want the existing conditions sheets submitted alongside the proposal. Many offices do.

How much do house plans cost in South Portland, ME?
One price list, applied the same way whether the house is fifty years old or not yet built.
| Tier | Price | Turnaround |
|---|---|---|
| Conceptual Drawings | $1,250 flat | About 1 week |
| Detailed Drawings | $2,500 flat | About 1 week |
| Architect-Sealed Plans | Custom | Varies |
Two revisions come with every tier at no charge, and if the city returns the drawings there is no limit and no bill for the rounds that follow.
An existing-house project carries the measuring work at the front, so tell us on the first call that the house is standing. It changes the schedule more than it changes the tier.
The reason this is worth paying for on a modest addition is that the alternative is a builder measuring for himself, quoting his own reading of the house, and being the only person who knows what was assumed.
That last part is the one that costs money later. When the only record of your house lives in one contractor's head, you are tied to him for every decision that follows, and you have nothing to hand a second builder if the relationship goes wrong.
A measured set puts everyone on the same page from the first quote onward. The builder is pricing your house rather than his impression of it, and you can hand the identical information to the next one without starting the conversation over.

Why does nobody have drawings of your house?
Ask ten owners of postwar South Portland houses for their plans and ten of them will look in the same empty folder.
These houses were built fast, in volume, for shipyard workers. That was the point of them. Whole streets went up to a handful of repeated layouts on a schedule nobody would attempt today, and the paperwork that existed served the builder rather than the buyer.
Whatever was drawn did not survive. Sets got thrown out at closing, lost in three changes of ownership, or kept in a basement that has since flooded. Seventy years is a long time for a roll of paper to stay with a building.
And the houses did not stay as built anyway. A porch got closed in. A breezeway became a room. Somebody finished half the basement in 1978. Even a surviving original set would now describe a house that no longer exists.
A town office will not have them either. Municipal records go back a long way for permits and rarely for drawings, and what is on file is usually a card rather than a set.
So when you decide to add a bedroom or open up the back of the house, you are not modifying a drawing. You are starting one.
That drawing is called a set of existing conditions, or an as-built, and it is the base layer everything else is drawn on top of. Walls, openings, ceiling framing direction, where the stack runs, where the panel is, which walls are carrying something.
It is not wasted money and it is not a formality. It is the difference between a designer proposing something buildable and a designer proposing something that turns out to sit on top of a bearing wall.
Almost every existing-house project we see here starts with this step, and the ones that try to skip it come back to it later at a worse moment.
Owners of postwar ranches and capes adding a bedroom, a bathroom or a family room. People opening up a closed-in kitchen who need to know what is holding the roof up.
Owners of winterized Willard Beach and Ferry Village cottages where four decades of additions have never been drawn.
Field measuring the existing house, drafting it as a dimensioned existing conditions set, then drawing the proposed work on top of it: plans, elevations, and the schedule of new openings.
On these houses, add the basement to that list. The stack, the panel and the bearing lines live down there and they decide what the floor above is allowed to do.
Allow for the measuring visit at the front. It adds a step that a new build on a bare lot does not have.
For a summer project, that means starting the conversation in winter rather than in April, because the drawings cannot begin until somebody has been to the house.
Because this is a town of existing houses rather than empty lots, so nearly every project here starts by documenting a building instead of inventing one.
A statewide fact worth carrying into your comparisons: Maine does not license general contractors or builders. Plumbers and electricians hold state licenses and nobody else does. A measured, dimensioned set is how you check a builder's assumptions against reality yourself.
What do South Portland homeowners ask about house plans?
What is an as-built drawing?
A dimensioned drawing of a house as it stands today. It becomes the base layer that any proposed work is drawn on top of.
Can you draw an addition without measuring my house?
No. Anything drawn against guessed dimensions gets caught at framing, and by then the fix costs real money.
My house has been added to twice. Does that matter?
It helps to know, and it is common here. Staged additions are exactly why the existing set has to be measured rather than assumed.
Does South Portland want the existing plans submitted too?
Often yes. Ask the city what they want with the application before the set is finalised.
How do you start a South Portland project?
Tell us the year the house went up and what has been added since. That decides how much measuring comes before any design.
