Part of Old House Projects Planning: Scope Through Closeout
Old house projects timeline: slower than owners expect
An old house projects timeline: the review cycles, permit queues, material lead times and seasonal windows that stretch the work, and how to plan around them.
What to take away
- Approval cycles, not construction, are usually the longest fixed item in an old-house schedule.
- Weather governs exterior work. Paint, masonry and roofing each have a season, and missing it costs months.
- Custom millwork, sash and matching materials carry lead times measured in weeks, sometimes in seasons.
- Build the schedule around living in the house, because you probably will be.
An old house projects timeline is not the same thing as a construction schedule. Old-house work slips for predictable reasons, and almost none of them are the contractor working slowly. Owners measure the calendar by construction alone, because that is the part they can picture. The review cycles, permitting queues, material lead times and seasonal windows that sit before and around the build are what stretch the job past the date in their head.
The fixed delays nobody can compress
Design review boards meet on a cycle, often monthly, and an incomplete submission costs a full cycle. Permit plan review takes as long as your jurisdiction takes. Utility disconnections and service upgrades sit on the utility's calendar. Specialist trades in restoration work are thin on the ground in most markets, and the good ones are booked out.
Sequential Delays to Add Up
- Review board meeting cycle
- Permit plan review time
- Utility scheduling window
- Specialist trade booking lead
- Add answers, don't assume overlap
Ask three questions before you set any date: how often does the review body meet, what is the current plan review time, and what is the earliest month the trade can start. Then add the answers together rather than assuming they overlap.
Multi-stage review is normal in preservation work, and the federal certification program is the clearest example. The program is the Federal Historic Preservation Tax Incentives program, run by the National Park Service with your State Historic Preservation Office, and it uses a three-part application from the NPS Form 10-168 series: Part 1 evaluates the building's significance, Part 2 describes the rehabilitation, and Part 3 requests certification once the work is finished. Parts 1 and 2 have to be approved before construction starts, and each part goes to the state office before it reaches the Park Service. Even where the program does not apply to you, the shape is instructive: sequential reviewers, each with a queue.
Season governs the exterior
| Work | Practical window |
|---|---|
| Exterior painting | Dry, moderate temperatures, avoid late fall |
| Repointing and masonry repair | Above freezing throughout the cure, avoid heat extremes |
| Roofing | Most of the year, avoid ice and extreme heat |
| Sash restoration off site | Any season, since the shop is heated |
| Foundation drainage | Dry ground, avoid frozen and saturated soil |
Sash work is the interesting row. Because it happens in a shop, it can fill the winter while nothing else can proceed, provided openings are closed with temporary panels. That asymmetry is the basis for phasing a window campaign across two or three seasons rather than trying to fit it into one summer.
Seasonal Windows for Exterior Work
Work
- Exterior painting
- Dry, moderate temps
- Repointing and masonry
- Above freezing, no heat
- Roofing
- Avoid ice and heat
- Sash restoration off site
- Any season, heated shop
- Foundation drainage
- Dry ground only
Practical window
- Exterior painting
- Repointing and masonry
- Roofing
- Sash restoration off site
- Foundation drainage
Read those windows as dates, not temperatures. In most of the country the exterior season opens after the last spring freeze and closes at the first hard freeze, so masonry and paint work have to be booked into the dry middle of the year. Look up your local freeze dates before you ask a painter or a mason for a start month, because a trade whose outdoor season is short books it fast.
Lead times on materials
Matching an old house means ordering items not stocked on a shelf, made to order: custom sash, turned porch parts, slate, matching brick and plaster moldings. Reproduction hardware is also made to order.
Ask for a written lead time with every quote, and treat the longest one as the true project start date.
Those written lead times belong in the same file as bids and change orders: the cost paperwork worth collecting before work starts.
Federal preservation practice takes the intervening period seriously. The Park Service's Preservation Tech Notes series covers it in "Temporary Protection of Historic Interiors," the note on temporary protection of historic interiors, which addresses exactly the situation where finished work has to survive months of ongoing construction around it.
Living in a half-finished house
Plan the sequence so a bathroom, a kitchen arrangement, and a sleeping area stay usable at all times, and stage work by floor or wing where the plan allows.
Agree in writing on daily working hours, dust barriers, and what gets cleaned at the end of each week. These terms determine whether a six-month project is tolerable or miserable.
A worked example
For a modest whole-house project: one to three months of investigation and design, one to three months of review and permitting, four to twelve weeks of material lead time overlapping that, then construction. Those first two phases alone put two to six months on the calendar before the contractor's quoted work begins, which is the gap between the schedule owners carry in their heads and the one the job follows. Construction is the phase that resists a schedule, since discovery is part of it, so treat the contractor's duration as the last number you add rather than the first. Money should be phased to match, which is covered in our restoration budgeting guide, and the full planning sequence sits in the start-to-finish project guide.
