"Caveat Emptor"

-

lee the buyer beware

-

is

the f i r s t and main rule the

buyer

nf an

older house,

or

of a n e w house f a r t h a t matter, should follow.

Once he has made his d e c i s i o n

and

signed the purchase agreement, there is

practically no way of reneging on it without substantial cost.

If the house is newly constructed by a reputable b u i l d e r , t h e purchaser

can be reasonably sure that h i s i n t e r e s t s have been protected by the

National Building Code of Canada (Part 9 Residential (=onstructfon) as Ear as

h e a l t h and s a f e t y requirements axe conmrned, and by t h e reputatton of the

h u i l d e r or hy s i t e inspectian during coastructibn by nunicipal and/or

Lnottgage company r e p r e s e n t a t Lves againat poor q u a l i t y work. Some f allures might happen, but these usually come ta light during the guaranty period and

are r e p a i r e d at no c o s t to the owner, Therefore, the prospective owner's

"new house Fnspection" d l 1 probably be aimed mure at suitability of room

layout, quality

of

f i n i s h e s , type of appliances included in t h e purchase

p r f c e , available colour schems etc., than at t h e actual construction.

Buytng an older house is another matter, The buyer, a f t e r satisfying

his concerns about the purchase price, q u a l i t y of t h e nefghbwrhood,

availability of schools, church, shopping, etc., should, before signing an

o f f e r t o purchase, i n s p e c t the Rwse (or have It inspected by a

knowledgeable person) for any faults which might

be

c o s t l y to repair later

and which might reverse h i s decision to buy.

This n o t e is an attempt to guide the buyer of an older hduse

In

making

s u c h an inspection. Attached checklists

for

emmarising your f i n d i n g s and

estimated costs f u r necessary repairs

will,

we hope, be af a d d i t i o n a l h e l p .

Be Prepared for the Inspection

L,et us presume that as a buyer, you

have

seen t h e house, you are

s a t i s f i e d as to a l l other subsidiary aspects of t h e purchase, your lawyer

has assured you that the t i t l e to the prbperty is clear, the money is in t h e bank or the mortgage is a l l prepared. B u t you s t i l l want t o gfve %t one

Last frlspectim before signing the agreement. Where do you s t a r t ? What d o you need? First

-

the building I s located on a p l a t of land. You need a

plan prepared by a registered land surveyor t o check all Ehe dimensions of

the l a n d you are a l l e g e d l y buying. You wf 11 need a tape measure t o take

dimensions, pad of paper and p e n c i l to make notes, Elashltght to see in

places where l i g h t is n o t provided, a laddsr or at l e a s t binoculars to check

the roof v i s u a l l y ,

a

knife or a w l t o a s t lumber f o r rot.

A

pair of

coveralls might n o t be a bad idea; you may need to climb into t h e a t t i c or

crawl space. If you are conducting the inspection on sowone else's b e h a l f ,

take a f l a s h camera along; i t will h e l p to document your find5ngs.

1. GROUNDS

1 . 1 Obtain registered plot p l a n prepared by lfcenced land surveyor-

Check q u a l i t y of paved driveway (including paving i n garage if any)

and entrance walkway.

A s c e r t a i n location of extsting b u i l d i n g and other structures on l o t .

If future additions are contemplated, check s e t b a c k s to lot l i n a s Eor

addition. (You may want to d i s c u s s c h i s with the m n i c i p a l zoning

of Eicer).

Check quality and material condition of adjoining decks and p a t i o s ,

Concrete elements might be damaged by frost action; wood parts might

be rotten beyond repair.

I n s p e c t the s t a t e of repair of retaintag walls if any.

Grading of land should provide

for

adequate drainage away from the

might be dangerous; they can be t o p p l e d by

wind m t o the b u i l d i n g or on overhead service wires. Check the h e i g h t

of trees and their condition. The tree root system drawing water from

surrounding so51 may cause the s o i l to ~ h r i n k in volume, r e s u l t i n g in

differential settlement and atructrlral damage, i . e . , cracked

foundation walls.

Check quality of the grsund cover

-

l a w n s and shrubbery.

2.1 Check foundation walls above grade f o r cracks and/or damaged cement

parging-

2.2 At t h e same time, check t h e e x i s t e n c e and location of the garden hose

b . Is if: t h e non-freeaing type?

2.3 What is the condition of the basement windows?

2.4 Exterior cladding

f o r rottfng wood (especially,close t o the grade, in corners and around

windows). Fresh paint might be hiding t h i s defect; test anyway.

If

siding is in bad shape, consideration c o u l d he gfven t o removing it

completely. It may be advantageous to add i n s u l a t i o n and i n s t a l l new

s l d f r ~ g over it.

2.5 Concrete exter tor s t a i r s = s t be checked €or cracks and spalling

stairs shauld he checked for p o s s i b l e settlement of footings. Check

(6)

Inspect; the windows from aurside. W i l l it be necessary to repaint

them? What is t h e s t a t e of m e t a l flashing, i f any? Cracked stone

window sills or lintels indicate some structural movement and damage.

Exterior doors s h o u l d be checked Ear quality, f i n i s h , l o c k s and

tightness, weather s t r i p p i n g . Check storm doors as well as garage

door, if any.

Evidence of efflorescence ar s p a l l i n g b r i c k s on t h e outside face of a

brick chimney means probable damage to the chimney l i n i n g . Also look

For damaged chimney cap and i n s p e c t metal flashing where t h e chfmney

structure meets the roof, If the c h l m e y is out of plumb or cracked,

a settled foundation and structural damage are indicated*

Inspect the roof surface. Missfng or c u r l e d s h i n g l e s will i n d i c a t e

necessary repair or replacemeat of roofing. Check f l a s h i n g s ac

valleys, fascia boards and soffits. Are soffit v e n t s prqvfded?

The presence of b l i s t e r s and r o o f i n g damage at perimeter flashing of a

f l a t roof will probably call f o r extensive r e p a i r s or complete

reroofing in the near future, I f not immediately. A l s o check

flashings at all prokrusibns through the roof. Check for "pending";

the roof may not be properly s l o p e d toward drafns.

Inspect all roof gutters and e x t e r i a r l i n t e r f o r drain p i p e s or drains

in a flat roof.

Check the underside of overhanging floors o r balconies. b o k

for

deteriorating finish and p o s s i b l e cracks due to overloading a r

displziremrtt.

Inspect a l l canopies over e x t e r i o r s t a i r s and porches for damage to

roofing, flashing, u n d e r s i d e f i n i s h and supports.

I n s p e c t a l l exterior r r i m f o r damage, r o t , flaking p a i n t and l o o s e

parts

3. BASEMENT

3 . 1 Check the width, headroom and handrails oE basement stairs €or

soundness,

If

you intend t o use the basement: as part of the l i v i n g

space (playroom, etc.), check whether the stair is comfortable t o use,

or can be a l t e r e d . (In older h m s e a , che haseeant s t a i r s are

sometimes more like ships' l a d d e r s , )

3.2 I n s p e c t basement w a f t s for cracks, efflorescence indicating a failed

dampness barrier or clogged perimeter d r a i n s and s i g n s of possible

basement f l o o d i n g . A mouldy s m e l l can be t h e first indication of

excessive moisture.

3.4 Basement f l o o r should be checked Eor cracks and s l o p e t o drain. Check

floor dtaFn if any.

3.5 Look f o r the sump p i t and check whether the sump pump is in working

order.

3.6 The basement g i v e s you Khe b e s t opportunity to inspect t h e q u a l i t y and

rype of materials used for plumbing. Look

for

damaged pipes and leaky

connections

.

3.7 Thesame capportunity p r e s e n t s itself t o check t h e w i r I n & r)ne

indication Chat wiring might have been upgraded is t h e presence o f

circrltt breakers on the d i s t r i h u t i o d panel.

3,s Check a l l a p p l i a n c e s

-

washer, dryer if any, laundry sink and h o t

water heater. Find out I f the water h e a t e r comes w i t h the house or I s

rented. Check

for

adequate water f l ~ w and drainage where

(7)

3 .9 To cheek the efficiency of the heating system you

will

probably need a

service man with an inspection kit. Ask for heating cost records;

t h i s might g l v e you an indication of what t o expect. Check the

furnace humidifier, if any, and

look

at the chimney cleartour

(if

there are black

streaks

around it, the chimney

will

need to be

cleaned). Check the q u a l i t y and tightness of the metal flue

connecting the furnace t o the chimney.

3.1 0 Inspect the basement wtndcms for deterioration,

s corm

windows, insect

screens, elosing/locklng devices.

3.1 1 Check first floor j a i a t a for r o t (especially at the ends) and

structural soundness (dangerously deep cuts t o aceommodate services or

drrit-yourself construction i n the basement; a sagging floor above

d g h t be the result).

3-12 Are the basement w a l l s insulated? Check insulation at top of basement

wall between the f l o o r joists.

3.13 Inspect a l l first floor beams and supportfng cc~iumns or p o s t s f o r

structural soundness.

3.14

If

the basement

is

"finished" try t o remove the f i n i s h i n g material

somewhere in a hidden corner and check behfnd i t for insulation,

dampness ( w i t h the vendor's p e r d s s i o n )

.

3.15 If the garage is located

in

the basement, check the walls and floor

s l a b for cracks, i n ~ p e c t area drainage f n f rout of garage door, floor

drain Inside garage. Door between garage and rest of the

house

mst:

have a

pr oper s e a l (we athers tripping)

.

3.16 If the house is built aver an unheated crawlspace, check the q u a l i t y

of supporting construction, i n s u l a t i o n of f l o o r and connecting pipes,

ground cover (building paper weighted down with sand or stones), screens or perimeter masonry enclosure, access t o t h e crawlspace and

its ventilation. Check for insulation of a heated crawlspace.

4.1

Check dimensions of a l l room including c l o s e t s against the s a l e s

contract: d e s c r i p t i o n . A sketch floor p l a n might be ueeful.

4.2

Inspect a l l doors for fit in frame, warpage and finish; checkthe

hardware*

4.3 Inspect a l l windms for tightness

,

weatherstripptug, f infsb, s torn

wf

ndws

,

insect screens and hardware {lacking devices). Dampness or

d i r t between panes o f double glazed

windows

indicates a damaged seal.

4.4

Check i n t e r i o r stairs for adequate w i d t h

(for

moving furniture),

headroom, q u a l i t y and soundness of r a l l % n g s , treads and s trlngers,

4.5

Inspect quality of wood floors or floor cwerings. Springy floors

might indicate problems with floor structure.

4.6 C h e c k w a l l and ceiling finishest for cracks, bulging, moisture stalns,

popplng n a i l s and other damage.

4.7 Inspect interior trim for damage, a n d q u a l i t y of

finish.

4.8 Check the kitchen for t h e quality and sLze of cupboards and counters,

note f i n i s h , type a£ kicchen aink and appliances if these are i n c l u d e d

(8)

4 . 9 Inspect bathrooms and powder room. Baw many are there? h w are

they finished? What i s the quality of bathroom fixtures? Are the

f i x t u r e s

of

w a t e r s a v i n g type? Are water faucets in good working order? U s t y streaks in

wash

b a s h and

tub

indicate

rusty

old pipes.

Is

there s u f f i c i e n t water pressure, e s p e c i a l l y at upper floors?

Is

mechanical ventilation provided?

4.10 What 1s t h e q u a l i t y of the lighting fixtures and the distributim of wall outlets throughout the house? Are f ire/smoke detectors installed

and operating? I n c o l d weather, check switches or wall wtlets

located on exterior walls for d r a f t . A cold stream of a i r coming out

of the switch

or

outlet indicates poor sealing of t h e air barrier i n

the wall.

4 , 1 1 I n s p e c t heatlng system o u t l e t s for damage, clostng and opening

devices.

4 . 1 2 Check the fireplace, i f any. Is t h e f i r e b r i c k l i n i n g in g o o d order?

Useful Hints

As mentioned before, preparing a dimensional sketch of t h e house a t t h e

time

of survey is a good idea.

It

serves several purposes. It

is

a

document of the survey, it can be used for locating various deficiencies

found in t h e course of t h e survey and f i n a l l y the new owner can use the

dimensioned sketched plans t o plan his new furniture lay-out before moving

into the house.

For example, s t a r t with Ehe elevations of the b u i l d i n g to get an i d e a

of Its overall shape.

To

have the p r o p ~ r t i o n s

of

the sketches r i g h t , f i r s t

draw a rough grid shoring the grade, imagined floor lines, eaves level l i n e ,

roof t o p line and connecting v e r t i c a l s , then f i l l i n t h e d e t a i l s , such as

door, wrlndows, and chimney. Hark f i n i s h materials on the sketch, as w e l l as

deficiencies found. A marked up photograph might s e r v e as well

(Ff

gure 1).

Then continue w i t h t h e ground floor

second floor p l a n ,

etc, It i s u n l i k e l y that you will need a section through t h e house ualass

there is something specific you would like t o show. When taking down

dimensions, first prepare a rough sketeh of the f Zoor you are measuring and

s t a r t for instance at the main entrance going clockwise a l l the w a y , so t h a t

you do n o t forget anything. It is recommended t o use running dimensions

(i.e. measure always from one fixed point

-

see sketch). Usually t h i s

requires t w o persons, one t o read the measurements fram the tape, t h e second

t o hold t h e tape in p l a c e and take notes. But it is more accurate than

single-handed, Bieasuee wall and partitfon thicknesses; d o not expect them

t o work out from other dimenalms. Watch for

v e r t i c a l

features t h a t allow

Eor

lmat3on crass check between floors such as stairway w a l l s or blocked-in stacks protruding from the wall. .Show h e i g h t oE ceiling in a c i r c l e . The

An o l d trick f o r measuring c e i l i n g height ( ~ i g u r e 3) where a

decorative cornice prevents taking measurement against the wall is t o open

the door and put a measuring rape against the door edge t o keep i t v e r t i c a l *

Another m e , shown in the

old books,

uses two measuring rode (or now

probably tapes) and an open sketch p a d t o relate insfde and outside

elevations at a ground f l o o r wludow (Figure 4 ) .

Floor-to-floor height: difference is best measured

in

the stairwell

you. Then pace back the d i s t a n c e t o the: o b j e c t and add 1.6
